Identifying the determinants of housing loan margins in the Hungarian banking system

Abstract and Figures

In recent years, the average spread on newly extended housing loans above the 3-month interbank interest rate has been consistently higher compared to spreads in neighbouring countries. This paper investigates the reasons behind it by using econometric tools and simple statistical examinations. In our two-step approach, we first identify the determinants of spreads based on Hungarian transaction-level and bank-level data, and then examine the Hungarian banking system's sectoral performance relative to other European countries in the main determinants identified. Our findings reveal that the higher spreads currently mainly stem from the high proportion of products with initial rate fixation of over one year, the relatively large stock of non-performing loans, and credit losses. High operating costs in international comparison may also have an impact on the setting of spreads. According to our estimates, demand-side attributes also contribute to the emergence of high spreads, as does the low level of competition in certain regions.

In recent years, the average spread on newly extended housing loans above the
3-month interbank interest rate has been consistently higher compared to spreads
in neighbouring countries. This paper invesgates the reasons behind it by using
econometric tools and simple stascal examinaons. In our two-step approach,
we rst idenfy the determinants of spreads based on Hungarian transacon-level
and bank-level data, and then examine the Hungarian banking system’s sectoral
performance relave to other European countries in the main determinants
idened. Our ndings reveal that the higher spreads currently mainly stem from
the high proporon of products with inial rate xaon of over one year, the
relavely large stock of non-performing loans, and credit losses. High operang
costs in internaonal comparison may also have an impact on the seng of spreads.
According to our esmates, demand-side aributes also contribute to the emergence
of high spreads, as does the low level of compeon in certain regions.

Interest rate level of household loans plays a pivotal role in shaping households’
nancial decisions. The interest rate, which is in fact the cost of funding, denes
along with the loan amount and maturity the burden that debt servicing
represents for the borrower, and thus a relavely higher interest rate can hinder
a signicant poron of households from accessing credit. Given that the Hungarian
populaon tends to prefer property ownership as opposed to property rental (MNB
2016), the pricing of housing loans is of parcular importance in Hungary.
In recent years, the average spread on newly contracted HUF-denominated housing
loans has signicantly exceeded the spreads seen in other regions of Europe (in

this study, the spread refers to the dierence between the interest rate on loans
and the 3-month interbank interest rate). Although the dierence between the
average annual percentage rate (APR) on new housing loans and the 3-month
money market interest rate has narrowed materially since 2014, the spread sll
exceeds the regional average by 1.6 percentage points and the euro area average
by 1.8 percentage points (Figure 1).
Seng the interest rate is a complex process that depends both on the instuonal
background of a country and its banking system and the bank’s own aributes
(Figure 2). The interest rates applied must be capable of covering the bank’s costs
associated with lending (Buon et al. 2010).
Funding costs. Financial instuons fund their operaons through other economic
agents, and so the price of the funds they receive plays a role in seng the price at
which they lend credit. The price of funds may dier based on loan type, maturity
and type of interest rate. Deposits are generally the most stable and cheapest form
of funding for loans. In addion, covered bonds, of which mortgage bonds constute
a subcategory, also play a major role in several countries (EMF 2012). Prior to the
onset of the crisis, securisaon was on the rise across Europe (ECB 2009), however
it fell short of the degree observed in the United States. Funding costs can also be

Idenfying the determinants of housing loan margins in the Hungarian banking system
shaped by various state subsidies. Housing loan support schemes are common, for
instance, somemes in the form of liabilies side interest subsidies. Due to these
factors, it is very likely that the internaonal comparison of spreads calculated based
on interbank rates contain biases.
Interest rate risk. The diverging interest rates on assets and liabilies represents
a risk linked to, but disnct from funding costs. The various countries dier
according to (1) the interest rate characterisc of various transacons and (2) the
other unique characteriscs associated with mortgage lending within the region.
For instance, transacons with rates xed over the longer term are predominant
in Belgium, Germany and France, while products that are repriced within one year
are predominant in Portugal, Poland and Ireland. The stability over me of the
proporon of various interest-bearing products also diers: while this proporon is
relavely stable in certain countries, in others, consumers acvely switch between
oang and xed-rate products depending on which seems more benecial at the
me (Johansson et al. 2011).1 This is relevant because consequently, the spread
may dier between two banks with idencal funding structures because one of
them mainly extended loans that are re-priced every three months, while the other
extended loans with a rate xed for ten years. For the laer, there is a signicant
risk of interest rate levels rising substanally over the ten-year period, which is also
reected in future funding costs. This must be taken into account in the interest
spread of extended loans. Prepayment by customers is also a source of risk, which
compels banks to extend the prepaid amount and interest rate environment
dierently — and typically lower — than the one prevailing at the me of original
loan extension. This may be parcularly problemac in countries where the
administrave costs of switching banks and prepayment are low.2
Operang costs. The upward impact of operang costs on interest spreads has
been demonstrated by many studies using various target and control variables
(Gambacorta 2014, Valverde – Fernández 2007). The impact of operang costs
may be parcularly signicant on household loans, as households are sll primarily
served personally, which requires the maintenance of signicant infrastructure (such
as a branch oce network), and the cost of this is reected in spreads. For this
reason, the eciency at which banks use their infrastructure is relevant, because
a signicant relave price decrease (for instance through digitalisaon) may be
reected in credit spreads.
1 Badarinza et al. (2014) demonstrated that the choice between oang- and xed-rate loans is mainly shaped
by the interest spread prevailing between the two product types at a given point in me, and the spread
expected in the short run. A volale inaonary environment should also be menoned: more volale prices
are generally associated with a lower number of xed-rate loans.
2 According to Hungarian regulaons, the early repayment penalty is capped at 2 per cent of the prepaid
amount. However, the debtor may terminate and prepay his debt at the end of the interest period or the
interest spread period free of charge if the interest rate or the spread are set to increase.

Credit losses. An inherent element of bank operaon is that some debtors will
not be able to service their debt. Banks must oset the losses incurred on these
loans through their interest rate spreads (and specically, the risk spread). So
the larger the expected loss on a porolio, the higher the interest spread that
may be necessary. Expected loss is shaped partly by economic fundamentals
(unemployment, changes in GDP, housing price developments) and partly by the
eciency of the legal instuonal system. It is important to note that expected
credit losses are calculated based on historical data, as a result of which a high
volume of non-performing loans may have a lasng impact on pricing. This means
that despite a far beer quality of currently extended loans, the bank may price
them as riskier based on its experiences derived from historical data. Although the
bank may incorporate forward-looking variables in its pricing model, the samples
oen available to banks contain observaons from the crisis period, and thus these
models may possibly capture a higher average risk level.3
Banks’ legal environment also has an impact on spreads. Mortgage loans are
collateralised products, which means that in the event of late payment by the
debtor, banks can hope to recover their loss by selling the property backing the
loan. The rate of recovery depends not only on changes in property prices, but
also on the strength and eciency of the tools available to nancial instuons
for enforcing their rights on the collateral. If legislaon impedes foreclosure (for
instance through long and costly foreclosure proceedings or other administrave

Idenfying the determinants of housing loan margins in the Hungarian banking system
constraints), banks’ expected losses and thus the spreads they apply will also be
higher. The internaonal literature demonstrated this eect both by examining net
interest income (Demirguc-Kunt – Huizinga 1999) and spreads on new loans (Laeven
– Majnoni 2005). Creditor banks’ opon for changing the interest rate through
the duraon of the contract also has signicance. If a bank is able to unilaterally
amend the interest rate at any point during maturity, it does not have to include
all expected future losses into the price at the me of contracng because it has
the opon of responding exibly. These types of loans were prevalent in Hungary
prior to the onset of the crisis, but signicant steps have been taken in recent years
to even out the balance of power between consumers and nancial instuons.4
In addion to the foregoing, the interest rate must also include a prot margin
allowing the instuon to generate the return expected by shareholders. The size
of the prot margin may depend on market structure, the level of compeon, the
instuon’s market power and the level of informaon held by potenal borrowers.
If compeon is weak and future debtors have poor nancial literacy and low price
elascity, then stronger market parcipants are able to enforce costs and high
prot goals in margins. Besides the impact of compeon, Ho and Saunders (1981)
also menon the risk aversion of management, average transacon size and the
variance of interest rates. However, there are contradicng views on compeon:
Maudos and Fernández de Guevara (2004) found that increasing market power is
associated with decreasing spreads.
In the following secon, we seek to idenfy the determinants of the relavely
higher average spreads on newly extended housing loans in Hungary. To idenfy
these determinants, we used econometric methods applied to several databases
alongside simpler stascal tools.5 Unfortunately, the available databases do not
include any that could provide a direct and certain answer to our queson (“Why
are spreads on new housing loans elevated by internaonal standards?”). We are
only able to use banking system aggregates in internaonal databases, and are thus
unable to control for either creditor or borrower composion. Data available only
at a low frequency and for relavely short periods make it even more dicult to
obtain reliable results.6
4 The legislave amendment on “transparent pricing” eecve from April 2012 is one such measure, which
substanally reduced banks’ leeway to unilaterally amend contracts. In keeping with this trend, the “ethical
banking system” regulaon introduced in 2015 only allows the amendment of lending condions based on
predened indicators approved by the MNB.
5 E.g. the examinaon of the composion eect.
6 Considering the available data, it is no surprise that the target variable of most papers published on the
subject is the net interest income role of prot and loss account, rather than the interest spread of newly
extended loans (see for instance Maudos – de Guavera 2004, Demirguc-Kunt et al. 2003, Saunders –
Schumacher 2000, Valverde – Fernández 2007). Using the prot and loss account as the point of departure
enables the use of bank-level internaonal data, but from the perspecve of this study, this is too broad of
a category that also contains non-relevant informaon.

As a result, we have opted for the following strategy: we aempt to explain
heterogeneity of Hungarian banks’ pricing behaviour using bank-level and
transaconal-level variables, and then examine the main variables idened within
the Hungarian sample in an internaonal comparison. We believe that a Hungarian
bank sets a higher spread compared to other banks based on a specic own
aribute, and then if the Hungarian banking system diers from the internaonal
average in terms of this variable, it may provide an explanaon for the higher spread
relave to other countries. However, it should be noted that this strategy is only
indicave and oers indirect evidence for the invesgaon of internaonally high
spreads, but does not provide a clear explanaon in methodological terms.
To answer our central queson, we performed esmates for three databases.
We examine the impact of bank credit supply and the contract-level aributes
of extended loans using a linear regression applied to microlevel data available
for 2014–2015 and using a panel model esmated for bank-level data between
2004–2014 for bank aributes. We then analyse the impact of demand aributes
using microlevel data available for 2015 using a mul-nominal regression. We
use various databases and methodologies in an eort to present and invesgate
the broadest range of aspects of the issue. This approach obviously comes at the
price of sacricing an in-depth examinaon of the dierent secons that would
be possible if we dedicated a separate paper to each part. We are aware of this
drawback, but nevertheless believe that this comprehensive approach will yield
the greatest benet in light of the relave underrepresentaon of the topic in the
literature.

The MNB’s public analyses (mainly the Trends in Lending and the Financial Stability
Report) generally present the dierence between the average APR of housing loans
extended during a given month and the 3-month BUBOR. However, the pricing of
housing loans may diverge substanally based on the term of interest rate xaon
by the bank for the reasons addressed in the previous chapter. Interest rates xed
for longer periods of up to 5 to 10 years currently materially exceed the inial
interest rate level of oang rate transacons that is ed to the reference rate
and thus changes relavely quickly. As menoned earlier, the main reason for this
is that economic agents generally expect interest rate hikes at the boom of the
interest rate cycle, so the cost of bank funds with rates xed for a longer period is
higher than the cost of shorter-term or oang rate funds (such as the 3-month
interbank interest rate). Banks may access funds with long-term xed rates either
directly or synthecally by interest rate swaps. In the laer case, the xed leg of
the interest rate swap represents the funding cost for the bank. If the bank nances
a xed-rate loan with oang-rate funds, the higher interest rate risk may warrant
11
Idenfying the determinants of housing loan margins in the Hungarian banking system
a higher spread. Based on the distribuon of new loans by the type of interest rate,
Hungary has a relavely high rao of loans with inial rate xaon of over one year,
especially by regional standards (ESRB 2015:28; EMF 2016).
Loans with inial rate xaon of over one year play a key role in explaining spreads
that are high even by internaonal standards. While the above-BUBOR spreads of
transacons with oang rates within one year already approached the levels of
other regional countries (Figure 3), the spreads of products with inial rate xaon
of over one year above the 3-month money market interest rate far outstripped
regional levels (Figure 4).7
7 In addion to the foregoing, there is methodological bias stemming from the fact that the spreads published
by the MNB are based on the APR, and are thus sensive to average loan contract maturity. The dierence
between the annual percentage rate and the interest rate is also shaped by other costs besides interest
(generally disbursement and loan assessment charges, handling charges), which increase APR expressed as
a percentage to greater extent if the maturity is shorter. The average maturity in Hungary in 2013 was 15
years, the shortest among EU countries. Within the region, Romania and Poland exhibit average maturies
of 25-26 years (ESRB 2015). A maturity of 10 years shorter results in an approximately 0.1 percentage point
increase in the APR characterisc of Hungary. A similar eect prevails when other costs are higher relave to
the loan amount taken out (such as nominally xed fees and lower average loan amounts), however there
is no available internaonal informaon on this.

Note: Spread above the 3-month interbank interest rate, interest rate based. This scheme does not exist
in Poland. For loans with initial rate fixation of over one year, the 3-month interbank interest rate may
diverge substantially from the actual cost of funding, so the spread presented by us may be partially
shaped by higher funding costs. Newly extended loans.

Idenfying the determinants of housing loan margins in the Hungarian banking system
Despite the relave widespread nature of products with inial rate xaon of
over one year, a signicant improvement has been observed in recent years in the
pricing of housing loans, as is also reected in the distribuon of spreads above
the BUBOR: In 2015, the distribuon of both oang rate products and products
with an inial rate xaon of over one year shied towards lower spreads relave
to 2014 (Figure 5).

Since early 2014, the MNB has compiled interest rate and other informaon on
new contracts on a transaconal basis. We therefore have a micro-level database
(with over 60,000 observaons aer cleaning the data8),9 which contains the date
of contract, the contracted amount, the maturity of the contract, the lending rate,
the type of the interest rate, the contracng bank, the loan’s subsidisaon status
and any associated collateral for all new housing loan contracts from 1 January
2014 onwards.
We were also able to associate bank aributes to individual contracts since we
have informaon on the creditor nancial instuon. In light of this, we can on
the one hand examine the impact of loan-level characteriscs on the spread while
controlling for the aributes of the creditor bank, and also analyse the paral eect
of bank aributes on spreads. It is important to stress that although we can control
for various loan contract aributes using variables of loan-level characteriscs, the
database does not include informaon on several important traits (such as income,10
collateral value, payment-to-income rao).
In order to idenfy paral eects, we use linear regression (OLS) where the
dependent variable is the spread above the 3-month BUBOR. During the esmaon
of the rst model, contract level characteriscs are given the main focus among
explanatory variables, and we control for the creditor bank using dummy variables.
In the second model, we use variables describing the bank’s operaon instead of
bank dummies in order to idenfy the paral eect of the laer. Santos (2013)
follows a similar methodology to examine the interest rates on loans to Portuguese
non-nancial corporaons. It is important to note that because the database only
8 When cleaning the data, loans extended by building sociees were also ltered out along with apparent data
errors on account of the special nature of these instuons and the schemes oered by them. In addion,
the model using bank variables does not include loans extended by cooperave credit instuons. This
is because the integraon process which cooperave banks underwent over the past two years makes it
uncertain whether individual instuonal aributes play a role in shaping spreads.
9 The main characteriscs of the database are presented in the Annex.
10 However, it is dicult to judge the customer’s income from this perspecve. The price seng of banks may
dier in terms of whether customer income only plays a role in accepng or rejecng loan applicaons, or
in the determinaon of the specic interest rate as well.

contains data for 2014–2015, the ndings can primarily be applied to these two
years. Because of the special nature of this period in various regards, we use longer
averages instead of the specic quarterly value for some of the bank variables:
Net credit losses: banks set aside provisions according to their expected losses.
However, the Selement of household loans decreased the gross value of loans
in 2015 H1, which also lowered the amount of expected loss, as the collateral
backing the loans retained its earlier value. The Selement thus decreased the
net value below the collateral value for a poron of loans, and as a consequence
wring back provisions was economically jusable in some cases. Several
instuons took advantage of this opportunity, but this development temporarily
concealed actual credit risk costs and losses in their prot and loss accounts. We
therefore use the average between 2008 and 2014 in the model.
Rao of net income from fees and commissions: the transacon fee introduced
in 2013 emerged as an “other expense” for banks, but due to the charge being
passed on to customers, its revenue side shows up among fee and commission
income. Consequently, the rao of net income from fees and commissions
increased arcially relave to interest income. In view of this, we use the average
value for the period between 2008 and 2012.
In light of the above, we esmate the following regression model that also includes
bank dummy variables:

where SPREADi is the spread above the 3-month BUBOR for contract i, i.e. the
dierence between the contractual lending rate and the average 3-month interbank
interest rate for the specic month. CONTRACT is the vector containing contract
aributes, and we include two dummy variables: one for the creditor bank and one
for controlling for me (quarter) of contracng. β0 is constant, β1, β2 and β3 refer
to the vectors of the coecients associated with dierent groups of variables, the
element number of which corresponds to the number of variables constung the
group of variables. The contractual variables used in the model are the following:
Maturity: the original duraon of maturity as specied in the contract, expressed
in months. The model also includes the square of the variable in order to idenfy
non-linear eects.
Contracted amount: the contractual loan amount expressed in HUF millions,
logarithmised. Similarly to maturity, we also included the square value.
Collateral dummy: if there is any collateral (generally real estate) associated with
the contract.

months, the dummy is 1; otherwise it is 0.

the rules dened in the state interest subsidy decree eecve in 2014-2015.11

In the second model, besides the above variables, we also include the following
bank variables (instead of bank dummy variables) (BANK_CHARACTERISTIC vector):
Proporon of liquid assets: the proporon of liquid assets (cash, selement
accounts, central bank bonds and deposits, government securies) relave to
the balance sheet total. We also include the square of the variable in the model.
Size of the capital buer: the dierence between the consolidated capital
adequacy rao (also factoring in Pillar II requirements) and the minimal regulatory
requirement. We also include the square of the variable in the model.
Operang cost to assets: the proporon of operang costs (personnel costs, other
administrave costs, depreciaon) relave to the balance sheet total.
Loan loss provisioning to assets: the average annual amount of the lending losses
relave to assets between 2008 and 2014.
Rao of branch oces: the rao of network units of a bank/banking group relave
to the aggregate banking system branch oce network.
Rao of net income from fees and commissions: the rao of net income from

The rst model using bank dummies gives an indicaon of the impact of contract
aributes on spreads. Based on the results of the model (Table 1, model (1)), the
higher the contract amount and the longer the maturity, the smaller the spread
above the BUBOR. However, this eect only applies unl a certain level, as shown
by the posive sign of the squared variables. The signicance of the loan amount
11 The subsidy is dierenated depending whether the loan’s purpose is to purchase used or new property.
In the laer case, the number of children in the household also inuences the subsidy. However, these
two pieces of informaon are not available, so we assumed that every loan was contracted to purchase
a used home. Based on aggregate stascs, this assumpon will not lead to any signicant errors, in view
of the fact that only a small fracon of newly extended loans were used to purchase new homes in 2014-
2015 (MNB 2016).

is presumably explained partly by the impact of income as an unobserved variable:
wealthier borrowers, represenng a lower risk tend to purchase larger properes
which calls for higher loan amounts. Economies of scale consideraons may
also have an impact: every loan contract comes with certain xed costs (such as
communicang with the customer, handling payment dicules), which requires
a higher spread on smaller credit amounts. However, above a certain level, potenal
loss rises and this is reected in the spread. For maturity, the negave coecient
may capture the eect of shrinking credit risks through the decreasing payment-to-
income rao. This eect however is oset by growing liquidity risks for loans with
very long maturies, so as the maturity grows longer, a higher spread is warranted.
As suggested by intuion, the collateralized nature of a loan decreases the spread,
while interest rate xaon of over one year increases the spread above the
interbank rate. Based on the esmate, the state subsidy also has a relevant impact.
In the database, we were able to observe the total interest rate received by the
bank, which incorporates state subsidies received as well. We are able to esmate
the approximate size of the subsidy based on the rules of the Home Creaon
Scheme being in eect in 2014–2015, and thus are also able to observe whether
the bank prices subsidised loans dierently depending on the amount of subsidy.
Our ndings show that for 1 percentage point of state subsidy, banks apply interest
rates that are over 0.3 percentage points higher on average, ceteris paribus. The
customer sll fares well, geng the loan at a spread that is 0.6 to 0.7 percentage
point smaller than the market rate in case of a 1 percentage point subsidy, while the
bank “keeps” 30–40 per cent of the subsidy. This nding may also give an indicaon
of the level of compeon.12
Based on the coecients idened above, changes in the general contract
characterisc of newly extended loans over the past two years have pointed towards
a reducon in spreads above the BUBOR. Since 2014, both the average of the
contracted amount and the average maturity have increased, while the proporon
of subsidised loans and the amount of state subsidy have connuously decreased,
due to the characteriscs of the pertaining regulaon,13 falling to minimal levels
by 2015 (from February 2015, the average market interest rate was below the 6
per cent corresponding to the lower threshold of the state subsidy). These three
12 Besides a low level of compeon, it may of course reects the impact of unobserved variables characterising
various bank porolios, that has been le out from the model. For example, if a bank specically targets
risky, lower-income customers with its state subsidised schemes, the higher spreads are indeed warranted.
However, the fact that borrowers are aware of state subsidy opons and may specically seek them out
irrespecve of their income status decreases the probability of this distoron. However, the restricons
of subsidisaon pertaining to property value increase the risk of bias.
13 According to the rules of the Home Purchase interest subsidy, the interest rate payable by the customer
must be no less than 6 per cent, so the subsidy can only lower the interest rate to this threshold. Given
that market interest rates approached and even dipped below this level, the state subsidy lost much of its
relevance compared to earlier, reected in the shrinking rao of subsidised loans.
17
Idenfying the determinants of housing loan margins in the Hungarian banking system
characteriscs have all fostered a reducon in transaconal interest rates, and
thus spreads.
For the model supplemented with bank variables, the signs of the coecients
discussed so far do not change, and they retain similar orders of magnitude (Table
1, models (2)-(7)). For bank variables, the credit losses of recent years and higher
operang costs were generally associated with larger spreads, which is in line with
our preliminary expectaons and the ndings of the internaonal literature. The
rao of net income from fees and commissions within net income of interest,
fees and commissions has a negave coecient, which suggests that banks which
generate income through other channels — for instance by selling other services
alongside loans — may take this into account by decreasing spreads. The rao of
liquid assets relave to total assets had a negave impact on spreads in the two
years under review, which may capture the price-reducing eect of growing credit
supply, while the posive coecient of the capital buer coecient may reect the
impact of higher cost of capital. The laer variable, however, loses its signicance
in the broadest specicaon. For both variables, the square values mostly have an
opposite sign (with the excepon of the capital buer, where the sign is the same
in the broadest specicaon, albeit the value of the coecient is parcularly low),
so these eects also only apply up to a certain level. The rao of branch oces
within the banking system branch oce network has a posive coecient, which
may capture market power: banks with relavely more branch oces may have
nearly exclusive presence on a greater amount of local markets, which they may
then enforce in their pricing. We address this eect in depth in the secon on the
model examining demand paerns (Chapter 5).

We also used a panel database for our analysis, compiled from Hungarian banking
system data that includes data on the major banks involved in housing lending in
Hungary between 2004 Q1 and 2014 Q4 (OTP Bank, MKB Bank, Budapest Bank,
FHB Bank, Cetelem Bank, Erste Bank, Raieisen Bank, CIB Bank, Unicredit Bank
and K&H Bank).14 Our approach was to use a regression model expressed for the
dierences of the dependent variable and that of the explanatory variables (3).
We esmated a model using xed eects broadly employed in the literature15, and
a dynamic model also containing the dependent variable’s lag, used more rarely
(e.g. Valverde – Fernández 2007).16
Because the presence of unit root processes could not be ruled out for level me
series and because error terms exhibited autocorrelaon when applying the xed
eect model, we instead chose to use a stac model containing the rst dierenal
of the variables:

Where Δy
it
is the annual change in housing loan margins, ΔX

is the annual change in
explanatory variables and δ
t
is the me xed eect . Because our panel is balanced,
the calculaon of dierences did not cause any signicant data loss. In the following
secon, we present the ndings of the model esmates, which proved relavely
robust for several specicaons.

The database allows the examinaon of bank-specic factors shaping banks’ pricing
decisions such as operang and funding costs, economies of scale and bank strategy.
Because similarly to the previous database, the sample only includes Hungarian
14 The housing loans oered by one bank are special in that they are pically unsecured transacons concluded
for “other” loan purposes, and as such, can be regarded as consumpon rather than housing loans. For
this reason, we also made the esmate with the omission of this bank and our results proved to be stable.
15 Based on the tests performed using the xed eect model, we cannot exclude the presence of unit root
processes for certain variables, so we rejected this approach due to potenal spurious regression bias.
16 Including the dependent variable lag may be movated by the raonale that when determining bank
lending spreads, earlier periods may serve as an anchor, and addionally, banks are not really capable of
reacng exibly when pricing loans due to market circumstances. Another advantage of this approach is
its capacity to address the endogeneity stemming from reverse causality, which in our case may emerge
in the variables related to bank porolio structure or in the NPL rao. But because the Blundell-Bond and
Arellano-Bond type methods available for short me series can be applied eecvely mainly with large
cross secon element numbers, in our case, esmang too many instruments created issues. Although we
tried out dierent dynamic models, we encountered troubles with model diagnoscs every me.

data, there is sll no way to conduct a direct internaonal comparison. However,
the 10-year horizon allows us to control for country-level cyclical macroeconomic
developments. In order to capture macroeconomic developments, we included
annual GDP in the model and also included me xed eects in an alternave
specicaon (Model 2). Among the variables used, the ones capturing credit losses,
such as the rao of non-performing loans, the loan-to-value rao and loan loss
provisioning, can be considered as cyclical as well. We also included indicators
represenng market power for the sake of capturing structural eects: the size of
bank branch networks and bank market share within household lending.
The ndings of the esmated model have limited reliability. The sign of key variables
is generally idencal to the ones dictated by economic theory, but signicance levels
are not stable across the dierent specicaons. Because banks are oen unable to
adapt on a quarterly horizon, we consider the ndings of the model expressed for
annual variables as the most convincing, so the following secon addresses these
in detail (Table 2). Overall, from our ndings indicave conclusions can be drawn
on the factors that shape housing loan spreads in the Hungarian banking system.

Variables: operating cost to balance sheet total, non-interest income/interest income, liquid assets/
balance sheet total, capital adequacy ratio expressed as a percentage, the share of fixed loans multipli-
ed by the slope of the yield curve (5-year government security yield 3-month BUBOR) taken into
account after 2010, the share of external liabilities within the sum of deposits (households and corpora-
te) and external liabilities, GDP growth expressed in percentage points, loan value to the property
pledged as collateral expressed as a percentage, share of non-performing loans in proportion to house-
hold and corporate loans, loan loss provisioning in the given period in proportion to the balance sheet
total expressed as a percentage, market share within the stock of outstanding household loans. We
included the annual change of each factor into the model. Because it takes different amount of time for
the changes of various factors to become incorporated into spreads, we applied an annual lag for ope-
rating costs and a quarterly lag for the capital adequacy ratio, the non-performing loan ratio and the
provision.

The individual bank factors capture, among others, the dierence between
banks’ business models. The coecient of the share of operang costs to balance
sheet total is not signicant, so in this model, we are unable to reliably conrm
the intuion that banks compensate higher operang costs with seng higher
prices.17 However, this result can also be distorted by the change in the rao’s
denominator (e.g. as a result of deleveraging aer the crisis). The rao of other
income to interest income is also not signicant at the usual signicance levels.
We featured this variable in the model to be able to control for bank strategies
that place greater emphasis on net income from fees and commissions, allowing
the bank to oer more aracve lending rates. The posive sign of the share of
liquid assets to the balance sheet total and the capital adequacy rao suggest
that banks incur addional costs to maintain excess liquidity and excess capital
which they compensate with higher prices.18 We examined the rao of xed rate
loans on variable interest rate loans for the post-crisis period in interacon with
the slope of the yield curve. Based on our expectaons, at those banks where the
rao of xed interest rate loans is higher, the aggregated spread is sensive to
the slope of the yield curve which captures the higher cost of funding and/or the
interest rate risk. This impact was signicantly idened during the panel esmate
on Hungarian banks. We included the variable of the share of external liabilies
to corporate and household deposits in the regression in order to control for the
dierence in business models among banks which are relying on and those which
are not relying on external funds. This variable is not signicant, that is, the results
of the regression do not suggest that banks would price dierently as a result of
their reliance on external funds.
Among cyclical variables, we go into detail about the impact of both the macro
variables and that of the individual bank variables related to the cyclical posion.
The negave coecient esmated for GDP capturing the economic performance
suggests the pro-cyclical nature of spreads. In the case of an economic contracon,
spreads increase in line with high risks as a sign of decreasing credit supply, which
further aggravates the contracon of the economy, while during a boom period,
banks lend with more moderate spreads, thereby further strengthening growth. The
LTV rao entered in the regression with a posive sign. The higher LTV rao reects
higher risk, since in the case of default the bank may migate or avoid credit loss by
selling the collateral. It should be noted that banks can compete not only in price,
17 What makes the idencaon of the impact of operang costs more dicult is that prior to the crisis
several banks gained market share through agent sales, the cost of which — as opposed to operang
their own branch network — did not appear among their operang costs. Considering that following the
onset of the crisis, agent sales decreased signicantly, this may also be the reason why operang costs sll
appear as a signicant factor in the case of a micro-level database only building on data from 2014-2015.
18 In the case of liquidity, this result contradicts the result of the esmaon conducted on the micro-database.
However, t the laer database covers only a two-year period while the panel database processes the data
of one decade, which means a dierence. On the other hand, the impact of capital adequacy is in line with
the results of the micro-database.

but also in lending condions, which may cause endogeneity for the LTV variable,
that is, in this case, the underesmaon of the coecient, especially if we examine
newly issued loans. The non-performing loan rao within the loan porolio of the
private sector (NPL) also correlates with the economic cycle: during the period of
an economic boom the share of the NPL porolio is generally low, while during
recession, this rao increases. The high NPL captures both already wrien-o and
potenally expected lending loss; accordingly, the sign of the variable is posive
in the esmated model. Similarly to the non-performance rao, provisioning also
reects the risks, but this indicator only includes the loss already wrien o by the
bank. The sign of the impairment is also posive in the model.
Because the development of economic growth in other countries was similar to the
Hungarian trend, the cyclical variables probably only explain some of the dierence
between spreads in the region. In our view, some structural reasons are also causing
the high spreads. We aempted to capture these factors by the share of the number
of bank branches and the banks’ market share on the household credit market. The
share of the number of bank branches in comparison to the number of branches
of the banks included in the model not only takes into account the bank’s own
branch network, but also the size of that branch network compared to that of the
competors. This variable is signicant and it is featured in the model with a posive
sign which suggests that banks operang a large branch network are able to use
their dominant posion on the market when dening the spreads on mortgage
loans. In our view, the role of the branch network is indeed relevant because the
majority of the populaon can select only from a limited number of banks located
near their place of residence, which decreases compeon between banks. The
market share variable is not signicant, so this simple control variable does not
conrm our impression that banks strive to use their dominant posion on the
market in their pricing.19
It may be a queson whether the levy on banks increased margins aer it was
introduced. We are unable to analyse this impact on the micro data due to the short
me period available, but we have included it in the panel model as an explanatory
variable. Based on our results, the impact of the bank levy is not apparent among
new loans, which also conrms the ndings of the literature according to which
banks have averted this extra cost by modifying the interest rate of their exisng
loan porolios (Capelle-Blancard – Havrylchyk 2013).
19 We can see in the correlaon matrix included in the annex that there is high correlaon between the
share of branches and the market share variable. For this reason, we decided to apply the model without
this laer variable, and the signicance level and the coecient of the branch-proporon variable did not
change signicantly either.

Along with supply factors, it is important to examine whether the demand side
supports the existence of a compeve market or whether there are any fricons
that could result in less compeon. As part of this invesgaon, we developed
a model which belongs to the family of discrete choice models. This allows us
to examine the factors that inuence consumers in bank selecon. During the
modelling, we relied on the Central Credit Register database which contains detailed
loan analycs for new disbursements, including customer characteriscs, from 2015
onwards. The nal model contains the data of seven major banks, covering more
than two thirds of the mortgage loan market. In the following, we present the
intuion behind the model and the main steps of the esmaon (esmang interest
rates and restricng the choice set) and we summarise the results of the esmaon.
We applied a mulnomial regression model for the analysis, placing consumers’
individual choices into the focus of the invesgaon. Factors inuencing the
decisions of consumers can be classied into three groups. First, the condions of
the selected loan product and the characteriscs of the selected bank play a key
role. Beside the interest rate, we can menon the factors that capture the quality
of bank services and that a past relaonship with a given bank may also be an
important aspect. Second, the customer’s taste also maer as the popularity of
the banks may dier in the various segments of the society. Third, the customer-
specic factors which are not observable by the researcher show up in the error
term of the esmate. Based on the above, following Train’s demonstraon (2002),
the ulity of the customer by choosing a given bank can be wrien as:
Uij =Vij xij ,si

Where U
ij
is the ulity of consumer i if he chooses bank j, x
ij
is the vector containing
variables which are customer- and also bank-specic (e.g. transaconal interest
rate). s

is the vector that contains solely customer characteriscs (e.g. age, income)
while ε
ij
is the model’s error term, which follows an i.i.d. extreme value distribuon
by assumpon. The model’s starng point is that customers strive to maximise their
ulity, that is, they opt for the oer promising the highest level of ulity compared
to other oers.

To esmate the model, we also need theorecal interest rate data that show the
interest rate at which the customer would have received a loan had he chosen
another bank instead of the observed choice. We esmated these theorecal
interest rates using linear regression, so that we created a unique model for every
bank where the dependent variable is the interest rate and the explanatory variables
can be classied into two groups. First, we included in the models the characteriscs
of customers who actually borrowed from the specic bank (age, locaon, income)
and second, we also controlled for the transacon aributes (value of the mortgage,
maturity, loan type). The explanatory powers of the models are high (R
2
around 0.9)
and their standard error is low (around 0.3 percentage points).
22
Despite the good
model stascs, the fact that this esmaon may be biased is an issue. The potenal
bias stems from the fact that the esmaon sample is not random, because banks
may be chosen by customers with strongly diverging characteriscs (self-selecon
bias). However, it is important to stress that this esmaon procedure is similar
to the procedure applied by banks, because banks themselves dene their pricing
models based on relaonships esmated with regard to their own clientele. In our
view, our esmated models feature acceptable accuracy and esmate for a sample
similar to banks’ samples, so these esmates provide a good approximaon of the
theorecal interest rate that banks have oered to prospecve borrowers.
Aer esmang theorecal interest rates, we also examined whether the
assumpon that households can choose from the oerings of all banks is well-
founded. We found that households faced both geographic and nancial constraints,
so it is likely that they can only choose from a narrow range of banks when making
mortgage loan decisions. The geographic constraints are reected in the fact that
22 R 2 (0.32) is low for a single bank interest rate model, however this model also yielded an esmate with
a low error (RMSE 0.33).

no more than two of the eleven major banks are present in half, and no more than
four are present in three-fourths of Hungary’s districts (Figure 6).23
Figure 7 captures the dierences in banks’ business strategies through the
distribuon of customer income associated with the loans extended in 2015. The
gure clearly shows that the banks marked by black mainly serve low-income
customers, while those marked by red mainly target higher-income customers and
barely lend to lower-income segments, or not do not lend to these segments at all.
The distribuon of loan size or the value of the property to be purchased shows
a similar picture. We used these ndings within the models to restrict the group of
banks that customers may choose from.
23 The distribuon of bank presence as a funcon of the populaon would be an interesng addion. More
than a quarter of the Hungarian populaon lives in a district where there are no more than two banks,
and nearly 40 per cent lives in a district where there are no more than four banks present from among
the eleven major banks. Only half of the populaon has access to at least six major banks in their region.

We run the nal model in eight specicaons; the results are listed in Table 3. In the
rst specicaon, we neither controlled for choice sets nor included demographic
variables (A1). The ndings of this esmate are not in line with expectaons,
because for example the interest rate coecient is posive, which is dicult to
interpret, as it suggests that consumers like high interest rates. This nding also
suggests that endogeneity distorts esmates, which may be because the impact of
demand and supply is not adequately disnguished in this specicaon.
For the sake of ruling out endogeneity, we implemented three changes in the
model. First, we incorporated demographic variables and bank dummies (A2, A4,
B2, B4), second, we restricted the choice sets (B1-B4), and third, we incorporated
a variable that captures previous relaonship with banks (A3, A4, B3, B4). We
obtained intuive results in each case, and the sign of the interest rate is negave,
which is in line with a negavely sloping demand curve.
In the models that included demographic variables and bank dummies (A2, A4,
B2, B4), the issue of endogeneity was signicantly reduced. The procedure applied
addresses the typical problem of a bank taking advantage of its strong brand and

lending at high interest rates in response to strong demand. Another key nding
is that by including demographic variables, clearly outlined taste paerns can
be idened. A good example of such paern is that based on the esmated
coecients, older age groups tend to prefer banks that have an established
presence on the Hungarian market, while younger age groups prefer newer market
entrants.
The models esmated by narrowing the choice set (B1-B4) may yield a more realisc
picture because banks that are not potenal choices for customers are le out of
the calculaons. Thus for instance, in the case of a low-income customer, obtaining
a loan from a bank that exclusively targets an auent clientele and oers low
interest rates is not a realisc opon. If we leave out this bank from the customer’s
potenal opons, it would lead to the false conclusion that although the customer
could borrow at a low interest rate, he instead chose to borrow at a higher rate. This
eect may be present in specicaon A1, where we did not control for the choice
sets. A key nding is that narrowing the opons alone results in the esmaon of
a demand curve with a negave slope (B1).
We also included a variable in the models that shows whether the customer has
borrowed from a specic bank (in the past eight years). This variable is signicant
and posive in every specicaon (A3, A4, B3, B4), which suggests that customers
prefer banks that they are familiar with in their borrowing decisions.
In every model, we included a variable among explanatory variables that shows
the number of branch oces that the bank has in the region where the customer
resides. This variable is also signicant and posive in almost every specicaon,
meaning that an expansive branch network is valued by customers.
Overall, the esmaon results suggest that the Hungarian populaon tends
to choose from a specic and narrow range of banks when making borrowing
decisions. This is partly due to the geographic distribuon of banks’ branch networks
and partly to the taste paerns prevailing within society; banks’ business models
are also relevant. These limitaons and paerns allow banks to price their products
according to oligopolisc compeon. These ndings conrm the outcomes of the
bank panel model invesgang supply eects, i.e. that the distribuon of branches
plays a key role in determining spreads. Finally, these esmates demonstrate that
structural factors play an important role on the Hungarian mortgage market.

In previous secons we listed a number of characteriscs that may potenally
explain the high Hungarian spreads. In line with our research strategy, in the
rst step we aempted to explain the heterogeneity of Hungarian banks’ price
seng behaviour by using bank-level and customer-level variables. The next step
is to examine the performance of the Hungarian banking sector compared to
internaonal examples with respect to the signicant variables idened in the
models esmated on the Hungarian sample.

Our main ndings, as presented in previous secons, were the following:
Through a composion eect, the higher share of contracts with an inial interest
rate xaon of over 1 year may account for the higher level of Hungarian spreads.
The slope of the yield curve may also contribute to the relavely high cost of
xed-interest loans.
An increase in GDP typically reduces spreads, while recession raises them.
Credit losses and the higher share of nonperforming loans may inuence the
spreads through higher risk costs, partly as a result of banks’ propensity to build
on historical credit experiences involving past – poor quality – loans.
Higher operang costs have been coupled with higher spreads in recent years.
The lower share of prots from fees and commissions may induce relavely higher
spreads.
Similarly, banks’ capital adequacy (capital requirement) may also exert upward
pressure on spreads.
There is a posive correlaon between the average loan-to-value rao of the
loans disbursed and the spread imposed.
Banks represenng a higher share in the branch network of the banking sector
applied, ceteris paribus, higher spreads.
The lack of a sucient number of market parcipants in certain regions and
debtors’ taste paerns may lead to the emergence of an oligopolisc market.
Unfortunately, owing to the limited availability of data, only some of these items
can be analysed in internaonal comparison. In the following, we focus our research
on items that – in light of the internaonal literature and/or our esmated models
– appear to be especially important, and for which relevant internaonal data are
also available. The laer may pose a problem mainly in relaon to the results of
the demand model; indeed, there is praccally no informaon available at the
internaonal level on debtors’ income status, their taste and on the distribuon of
branches. We will not go into detail about the topic of liquid assets and the loan-
to-value rao because – although we found some evidence that these indicators
and the size of the spreads are posively correlated – internaonal literature does
not provide clear guidance on the impact of such aributes on spreads.

As pointed out above, the outstandingly high Hungarian spreads observed at the
end of 2015 and in early 2016 can be primarily aributed to the higher spread on
loans with an inial interest rate xaon of over 1 year. The spread between these
lending rates and the interbank rate is partly determined by the yield curve; indeed,
in the case of a steeper (and upward sloping) yield curve, the creditor bank will
also face increased costs of funds when borrowing funds with a long-term inial
rate xaon and consequently, this premium will be priced into the bank’s lending
rate. If the bank relies on short-term and/or oang rate funds to nance loans
extended with a long-term rate xaon, the interest rate risk thus incurred by the
bank juses an increase in the spread. Based on Eurostat data, the yield curve is
relavely steep in Hungary compared to other EU countries. At the end of 2015,
the spread between the ten-year government bond yield and the three-month
interbank interest rate took the h highest value in Hungary.

As at end-2015, data reveal that in Hungary, the share of products with a rate
xaon of over 1 year was high even though Hungary recorded one of the highest
interest spreads between xed and variable rate products (Figure 8). It should
be noted that, if the interest rate spread between two product types reects
the expected interest rate path, in theory, choosing between the two products
would not make any dierence for a raonal consumer, provided that his interest
expectaons coincide with market expectaons. Experience, however, shows
that instead of looking at the interest rate path as a whole, consumers are far
more concerned about the interest rate spread prevailing at the me of the loan
disbursement and during the short period that follows (Johansson et al. 2011;
Badarinza et al. 2014; Holmberg et al. 2015). It should also be remembered that,
as noted in the introducon, it is oen the given country’s lending “tradions”
or instuonal background that determine consumers’ decisions as they select
from the product types available. Having said that, since the surge in household
lending at the beginning of the 2000s, it has only been observed in recent years

Idenfying the determinants of housing loan margins in the Hungarian banking system
that households are more likely to become indebted with xed interest rates, on
a market basis (without any state subsidy).
We also analysed the gure above aer adjusng the interest spread by the
dierenal between the 5-year interest swap relevant to the given currency and
the short-term interbank interest rate. Our goal was to exclude, as far as possible,
the eect of interest rate path expectaons from the premium shown in the gure,
in order to obtain a beer approximaon of the “pure” dierenal concerning the
raonal consumer.
24
Based on the values thus received, in Hungary the premium on
xed-interest loans is higher than would be warranted by the dierence between
funding costs; consequently, we sll cannot consider the increase in the share of
xed-rate loans as being trivial (Figure 9).
We believe that the substanal share of xed-rate products suggests that the
Hungarian populaon is more risk averse than borrowers in other countries; indeed,
Hungarian customers are willing to pay a much higher premium for a xed interest
rate. This, in itself, does not imply that this premium (or at least a part of it) is
not jused; it is an interesng development, however, that Hungarian household
debtors are apparently more likely to pay a considerably larger sum in exchange
for a smaller deviaon in monthly payments. In our opinion, this may also reect
households’ negave experiences with foreign currency loans and the extremely
volale instalment amounts associated with them. Banai and Vágó (2016) also
conrm that foreign currency lending gave rise to precauonary moves among
households: based on data derived from the Austrian central bank’s Euro Money
Survey, the authors provided evidence that the negave experiences associated
with foreign currency lending clearly set back credit demand. It is also conceivable
that the “demand” problems presented in Secon 5 can be perceived more strongly
– possibly because of the limited number of acve market parcipants – in the
market of xed-interest loans. The picture appears somewhat more complex once
we consider that the high rao of xed-interest products has partly resulted from
the acvity of building sociees issuing xed-interest loans. Nevertheless, it is also
true for these instuons that the interest rate they impose exceeds the interest
level of variable-rate products; in other words, the customers of building sociees
will also pay the premium between the xed rate and the variable rate in exchange
for a predictable interest rate.
24 However, this method should be viewed as an approximaon only; indeed, the dierenal between the
average interest rate on actually disbursed xed-rate loans and the interest rate on variable-rate loans can
also be inuenced by composion eects, especially when a parcular product has gained dominance in
the given country. Various sub-markets may be dominated by dierent creditors and borrowers and the
dierent characteriscs of these market parcipants may also be reected in aggregate interest rates.
Consequently, the “pure premium” could not be presented even on the second gure.

Model esmates have demonstrated that the rao of credit losses and non-
performing loans play a prominent role in credit spread developments. In calculang
their rate of return, banks should consider the probability of a borrower’s falling into
delinquency during the term of the loan, and calculate the expected recovery rate
on the collateral in case of the borrower’s delinquency. The calculaon of expected
losses is based on historical data; consequently, a substanal non-performing
porolio may have a long-term impact on price-seng. Based on the distribuon
of NPL raos, Hungarian banks are among the more aected instuons of the
region, which may have contributed to the emergence of higher spreads (Figure 10).
Collateral recovery and the eciency of enforcement proceedings play a key role in
credit loss developments. Hungarian legislaon has signicantly hampered banks in
the acquision and sale of real estate property in recent years. Moreover, the legal
environment protecng debtors movated even performing debtors to suspend
their monthly payments, generang even more credit losses for banks (Dancsik
et al. 2015).

Operang costs have an intuive role in the evoluon of spreads, as banks need to
set a price that allows them to achieve prots. Banks’ lower eciency and higher
costs may also call for higher spreads. We demonstrated this eect successfully in
the model featuring microdata; however, we did not receive signicant results in
the panel model. This may be partly aributed to the costs of agent sales preceding
the outbreak of the crisis, as they were not part of banks’ operang costs.
Based on the internaonal data available, the Hungarian banking sector is among
the less cost-ecient banking systems (Figure 11). Obviously, the magnitude of
operang costs cannot be fully separated from non-performing loans; indeed several
items related to the management of the NPL porolio raise the costs incurred by
banks. Such costs include, for example, the need for personal treatment in the
case of a bad loan, or the connuous safeguarding and potenal upkeep of already
recovered collateral.

applied by the bank (standard or IRB method), but for lack of internationally available data, we are
unable to assess the magnitude of this effect. In certain countries, there were few banks for which infor-
mation was available and the distribution might only reflect the data of a single institution or an ext-
remely limited number of institutions.

According to the ndings of the internaonal literature, banks are more prone
to set lower interest rates if they also collect income from services other than
loan contracts. Although this was conrmed by the esmates we performed on
microdata, it was not a signicant variable according to the results of the panel
model. In Hungary, the rao of net income from fees and commissions is relavely
small compared to other European countries (Figure 12), which may also contribute
to higher spreads.

Our models demonstrated that a higher stock of capital is generally associated
with higher spreads. This eect has been idened in the internaonal literature
as well. Based on the CET1 (Common Equity Tier 1) rao – which is composed of
the best capital elements – Hungarian banks cannot be deemed overcapitalised by
European standards (Figure 13). It hinders data comparability – especially in the case
of CEE countries – that the capital posion of a bank largely depends on the capital
allocaon strategy pursued by the non-resident parent bank, i.e. in which country
the bank holds the buer set aside on top of its consolidated capital requirement.

Idenfying the determinants of housing loan margins in the Hungarian banking system
It is not only the size of the capital buer that is relevant to a bank’s capital posion,
but also the expected minimum statutory adjustment to its level. In parallel to the
development of macroprudenal strategy, regulatory authories have gained access
to several new discreonary instruments in recent years that exert an impact on
banks’ capital posion (systemic risk buer, countercyclical capital buer, capital
buer applicable to systemically important instuons). In Hungary, the level of the
countercyclical capital buer has remained at zero per cent since its introducon,
but the other two instruments have higher levels. In our opinion, however, these
rules cannot be a signicant factor in the deviaon of Hungarian spreads from the
internaonal average; rst, because they are also used in other countries (ESRB
2016:52) and second, because banks are only required to comply with these two
rules, for the rst me, from 2017, which means that their eect must have been
rather muted during our review period (2014–2015 and 2005–2014).

long me horizon, we aempted to idenfy the determinants of the spreads on the
basis of Hungarian bank and transacon-level data. In the last step, we examined
the Hungarian banking system’s sectoral performance relave to other European
regions with respect to the main determinants idened.
Our results showed that the spreads diverging from those of the region are primarily
caused by the higher spreads applied for loans extended with an inial interest rate
xaon of over 1 year, while the spread on loans with short-term variable rates has
already approached the regional average. Although the dierence between the
interest rates on variable and xed-rate loans is relavely high in Hungary (partly
as a result of the steeper yield curve), the share of loans with an interest rate
xaon of over 1 year within newly disbursed loans is over 50 per cent. This means
that borrowers are willing to pay a high premium in exchange for a xed interest
rate, even when adjusted for the higher costs associated with xed-interest funds.
Households’ negave experiences during the period of foreign currency lending
may have been an important contributor to this risk aversion.
The rao of non-performing loans, which is also high by internaonal standards, may
have been another factor in the emergence of high spreads. Banks set their spreads
in consideraon of the credit losses incurred, and higher credit risks are typically
coupled with higher spreads. Through collateral recovery rates, the eciency of
the legal enforcement system may also play a role in the evoluon of the spreads.
According to our esmates, the high share of operang costs may also induce
higher spreads. Banks’ expected rate of return will warrant higher spreads if their
cost-eciency is inadequate. The relavely small impact of other net income items
may also play a role: banks are more prone to set higher interest rates if they do not
collect income from any other services. We could only demonstrate these last two
eects in our esmates performed on microdata. Even in terms of these variables,
the performance of the Hungarian banking sector is worse than the internaonal
average.
Our analysis also suggested that, owing to customers’ limited price exibility and
the geographical distribuon of branches, compeon is inadequate in the eld
of housing loans. Our demand model showed that, on the one hand, customers
face geographical limitaons: only a strictly limited group of banks has presence in
many Hungarian administrave districts and customers tend to choose the easily
accessible banks. On the other hand, banks’ business models also reduce the
number of instuons that are perceived by consumers as potenal opportunies;
indeed, the banks which target auent customers do not make eorts to serve
low-income customers.
Thirdly, certain taste paerns suggest that customers rely on an extremely limited,
preferred group of banks in making their borrowing decisions, and are only willing
39
Idenfying the determinants of housing loan margins in the Hungarian banking system
to compare the oers of these chosen banks. These factors, overall, enable banks
to set their prices in the context of oligopolisc compeon. It is also a sign of weak
compeon that banks do not pass on to customers the full subsidy in the case of
subsidised loans as they – according to our esmates – overprice these loans by
about 30–35 per cent of the subsidy.

... The APRC was 4.49 per cent for loans with an interest rate fixation of 1-5 years, 5.22 per cent in the case of 5-10 year fixation and 5.66 per cent over 10 years. 5 Based on the data, however, banks set substantially different spreads for these two product types for a long time; in other words, the spreads on loans with an initial interest rate fixation of over 1 year were higher than justified (Aczél et al. 2016;MNB 2017). This discrepancy could be observed up until 2018, when the two spreads converged (MNB 2018b). ...
... The estimated coefficients of the models of the total banking sector are shown in Table 6. 20 The direction of the coefficients estimated by the model is consistent with the intuition and with the model results estimated by previous studies (Aczél et al. 2016;Mérő and Vágó 2018). The explanatory power of the models amounts to 44 per cent in the case of the banking sector estimate (based on R 2 statistics), and ranges between 8 per cent and 72 per cent in the case of individual bank estimates. ...
... The methodological implementation of our analysis, which focuses on the impact of energy efficiency on interest rates, is based on the previous studies in the Hungarian literature in which the authors aimed to identify factors explaining lending rates (see, for example Aczél et al. 2016;Dancsik -El-Meouch 2019). In addition to the explanatory variables used in the literature, we also include variables controlling for the location and quality of the property, based on the ING database, in order to accurately estimate the partial effect of the energy performance certificate. ...

The real estate market is a key component of the green transition, and thus it is worth examining the pricing and financing costs of modern residential buildings in Hungary. In our study, we investigate a) whether a significant price premium can be identified for green properties based on new housing projects in Budapest, and b) whether banks finance residential buildings with more advanced energy technologies at lower interest rates. Based on our regression estimation, the green price premium is clearly evident in the Budapest new housing market: on average, homes with an energy rating of BB or better are 5.1 per cent more expensive than homes with an energy rating of CC. Based on our estimate of housing loan interest rates, no significant difference can be identified in the interest rates on loans granted to finance properties with a certificate higher than CC compared to loans granted for properties with CC certificate, i.e. banks do not yet factor energy aspects into the pricing of loans.
... The BIRS also plays an important role in determining the interest rate and its changes with respect to Hungarian housing loans, because these interest rates also serve as the basis for several "fair bank" indicators used for repricing. 5 For a detailed summary of the main institutional and banking factors shaping interest rates, see Aczél et al. (2016).

In the Hungarian banking system, newly disbursed, fixed-rate housing loans are typically repriced with a lag of several months after a change in the interbank rates, which can be viewed as the cost of funds for institutions. This paper examines the number of months it takes for a change in the interbank rates to pass through to the interest rates of newly disbursed housing loans with an initial interest rate period of over one year. The two-step analysis looks at the repricing practices observed for Certified Consumer-Friendly Housing Loans (CCFHLs) employing a descriptive approach, and then a vector autoregressive model is used to estimate the speed at which interbank rates pass through to aggregate housing loan rates. Based on the authors’ estimate drawing on aggregate interest rate statistics, the changes in interbank rates are incorporated into the mortgage rates applied by Hungarian banks in approximately four months; however, according to the interest rate condition data of institutions’ CCFHL announcements, banks’ repricing practices vary, leading to differences in the speed and extent of the interest rate changes following a shift in the cost of funds.
... In the case of mortgage lending using real estate as collateral, the purpose of the loan is usually the purchase or construction of the property itself, which also serves as collateral for the loan. Real estate collateral provides the debtor with more favourable credit terms compared to an unsecured loan (Aczél et al. 2016), as it reduces the lender's risks by allowing the value of the collateral to be used to satisfy the debt in case of default, and therefore plays a significant role in lending; accordingly, knowing value of the collateral is of paramount importance. For decades, financial regulation has been challenged by the issue of accurately determining (estimating) the value of the property that is the collateral behind a mortgage loan, which is constantly changing depending on a number of macroeconomic and financial indicators. ...

The valuation of real estate collateral is a long-established area of the lending process that is currently undergoing increasingly dynamic development and in which the use of statistical valuation methods is becoming more and more common instead of on-site valuations. The legal conditions for this have been created by amendments to European and national legislation in the past year, but for the method to be truly widely used and operational and to ensure the accuracy of the resulting valuations, access to detailed, accurate, up-to-date and regularly checked data on real estate must be also created. As the databases currently available for Hungarian real estate are very fragmented, in our study, we propose to create a central database that would provide a uniform, up-to-date set of data, by harmonising the existing separate databases. Such a database would help create a level playing field in the market and automate data transfer in a cost-effective, fast and reliable manner. This would greatly facilitate the uptake of statistical valuation methods, supporting the further spread of digitalisation, increasing banking competition, speeding up administration and reducing the cost of lending for all parties.

This paper analyses the fundamental determinants of the household borrowing decisions in Hungary and Poland, using the Euro Survey data conducted by the Austrian central bank. The previous researches, based on the Euro Survey, are supplemented and enhanced in several respects. It bears utmost importance that instead of using simple ad hoc methods to manage the problem of missing data we got more reliable results by applying multiple imputation technic. We show that former relations of different factors change in the crisis, so different periods should be examined individually as well. According to the results, credit demand was determined in both countries by the trust in the institutional system, the financial awareness/education and the economic expectations. However, the impact of the various socio-demographic variables differs in the two countries. E.g. in Hungary households in poorer regions tend to have higher credit demand before the crisis and lower demand in the crisis. The paper also presents that in Hungary the negative experiences related to foreign currency loans have a major effect on the borrowing decisions. Finally, it is demonstrated that self-selection has a material role in household lending as well, i.e. the customers who assume that they are not creditworthy, do not even try to apply for loans.

The severity and longevity of the recession caused by the 2007 financial crisis has highlighted the lack of a reliable macro-based financial regulation framework. As a consequence, addressing the link between the stability of the financial system as a whole and the performance of the overall economy has become a mandate for policymakers and scholars. Many countries have adopted macroprudential tools as policy responses for safeguarding the financial system. This paper provides a literature review of macroprudential policies, its objectives and the challenges that a macro-based framework needs to overcome, such as financial stability, procyclicality, and systemic risk.

The form of the interest rate on newly issued mortgages, namely whether they are adjustable-rate mortgages (ARMs) or fixed-rate mortgages (FRMs), varies considerably both across countries and over time. We attempt to uncover the sources of this variation in the "ARM share" of ARMs issued, relative to total mortgage issuance. Our emphasis is on drawing inferences about how household mortgage choice is affected by households' reactions to movements in interest rates. We complement newly assembled panel data from nine countries on the ARM share and mortgage interest rates with a panel instrumental variables approach in which we test exclusion restrictions that are implied by alternative explanations for variation in the ARM share. We uncover strong evidence in favour of current cost minimization as the proximate driver of household mortgage choice.

This report analyses the main developments in housing finance in the euro area in the decade, covering the period from 1999 to 2007. It looks at mortgage indebtedness, various characteristics of loans for house purchase, the funding of such loans and the spreads between the interest rates on loans granted by banks and the interest rates banks had to pay on their funding, or the return they made on alternative investments. In addition, the report contains a comparison of key aspects of housing finance in the euro area with those in the United Kingdom and the United States. At the end, the report briefly discusses aspects of the transmission of monetary policy to the economy.

This book describes the new generation of discrete choice methods, focusing on the many advances that are made possible by simulation. Researchers use these statistical methods to examine the choices that consumers, households, firms, and other agents make. Each of the major models is covered: logit, generalized extreme value, or GEV (including nested and cross-nested logits), probit, and mixed logit, plus a variety of specifications that build on these basics. Simulation-assisted estimation procedures are investigated and compared, including maximum simulated likelihood, method of simulated moments, and method of simulated scores. Procedures for drawing from densities are described, including variance reduction techniques such as anithetics and Halton draws. Recent advances in Bayesian procedures are explored, including the use of the Metropolis-Hastings algorithm and its variant Gibbs sampling. No other book incorporates all these fields, which have arisen in the past 20 years. The procedures are applicable in many fields, including energy, transportation, environmental studies, health, labor, and marketing.
Article
Using a Merton model framework (consistent with Basel II formulas), we develop a methodology for point-in-time (PIT) and through-the-cycle (TTC) probability of default (PD) decomposition in credit risk classification systems, primarily for corporates. Such a methodology is important for reducing the procyclicality of the capital requirement. We mathematically define the degree of PIT of a rating model and the state of the economic cycle. Simple analytical expressions for full PIT PD and TTC PD are derived, which allow easy implementation of the methodology in a bank's IT system. Furthermore, we discuss different methods for estimation of parameters as well as possible implications for risk adjusted profitability and steering.
Technical Report
The report investigates how structural features of, and cyclical developments in, residential real estate (RRE) markets in the EU may affect financial stability and how related risks can be addressed. The report is structured in four main sections covering: (i) an analysis of the structural features of RRE markets in Europe, (ii) the historical experience in Europe as regards financial stability risks emerging from the real estate sector, (iii) an investigation into the possible role of structural features of RRE markets in such risks, and (iv) the policy instruments that can be used to address the risks stemming from residential property markets. i) Analysis of the structural features of RRE markets The structural features of RRE markets can be usefully grouped into demand-side, supply-side and institutional factors. Demand-side factors include household income, credit availability and interest rates, home ownership rates, and demographic factors. Supply-side elements encompass factors such as residential investment, housing construction and construction costs. Institutional factors include housing taxes and subsidies, mortgage contract features (e.g. variable vs. fixed rate contracts), as well as foreclosure and insolvency procedures. The report shows how EU Member States differ widely in terms of these structural features. For example, in the Netherlands and Estonia, housing taxes decrease the marginal cost of acquiring a house, while in France and Greece they increase the costs substantially; in Sweden the average mortgage maturity is more than 40 years, while in Hungary it is only 15 years. ii) Historical experience of RRE markets and financial stability risks The report develops a conceptual framework of how the housing market, real economy and financial sector are interlinked. Tight links tend to reinforce feedback loops between the financial sector and the real economy. Structural features of national RRE markets may further amplify or dampen the transmission channels. Several indicators relevant for a financial stability analysis of RRE markets are explored conceptually and empirically. An existing ESRB database is used to identify real estate-related banking crises, with the report also exploring several measures of the depth of a crisis. The report identifies possible indicators that might be particularly relevant during the build-up of financial stability risks in RRE markets and investigates how they behaved prior to the recent financial crisis. Different indicators may be useful depending on the phase of the real estate cycle. Possible early warning indicators of a real estate boom include cyclical indicators of credit and/or real estate prices, combined with their corresponding structural indicators (such as bank credit-to-GDP and price-to-rent ratios); relevant indicators for the bust phase include decreases in loan supply and house prices, and rising non-performing loans and bankruptcy rates. Finally, the similarities and differences between the most recent crisis and the real estate-related banking crises of the 1990s are explored. The analysis of real estate indicators has highlighted that comparable high-quality data on some key metrics for financial stability monitoring and policy-making are still not available. The expert group therefore recommends that harmonised definitions of key indicators, such as LTV, LTI, DTI and DSTI, be developed, at least for monitoring and cross-border comparison purposes. These harmonised indicators should not prevent national authorities from continuing to use indicators based on their own definitions to accommodate national specificities. An analysis of the time-series behaviour of key cyclical real estate-related indicators around crisis events leads to some interesting conclusions. Crises tend to be preceded by lower funding costs, better access to credit, rising debt levels and an underestimation of risks. Risks and vulnerabilities accumulate in the form of external imbalances, booming construction activity, excessive bank credit growth, higher private sector leverage, and overvalued RRE prices. iii) Structural features of RRE markets and financial stability risks The analysis points to sharp differences across countries both in the incidence and depth of RRE-related crises. The report provides a first analysis of the potential interplay between structural and cyclical features of European RRE markets and financial stability risks using both graphical and econometric analysis. Structural market features may increase vulnerabilities before real estate-related banking crises and can exert an amplifying or dampening effect when the crisis materialises. However, the role of structural features of real estate markets in shaping the real estate cycle and how they affect financial stability is difficult to assess. The report finds preliminary empirical evidence that structural features do matter for financial stability. Initial results highlight the role of structural features, such as high LTV ratios, a favourable tax treatment of housing and high levels of bank leverage, in increasing the vulnerability of countries to real estate-related distress events. Empirical work suggests that high shares of new lending granted at a variable rate, by contrast, are associated with a lower probability of upcoming distress, though this result is likely to depend crucially on the evolution of the interest rate environment. While structural market features may indirectly influence cyclical developments in the build-up phase, they are likely to directly influence the depth of a crisis. Imbalances and structural developments during the upturn phase are perhaps more likely to affect resilience to a negative shock, rather than influencing the likelihood of that shock occurring. Future research would be needed to analyse more closely the depth of real estate-related banking crises, and the role of cyclical and structural characteristics in shaping the impact of crises. iv) Policy instruments to address financial stability risks Real estate macroprudential instruments can be grouped into those tackling three “stretches”, notably relating to borrowers’ income, the underlying collateral backing loans and banking system resilience. In recent years, instruments related to income stretch (LTI and DSTI caps, affordability requirements, amortisation requirements), collateral stretch (LTV caps, amortisation requirements), and banking system stretch (sectoral capital requirements) have been introduced in a number of Member States. The report provides guidance on the design and use of instruments drawing both on analytical work and emerging experience across countries. A careful design of instruments is crucial for enhancing their effectiveness and avoiding any potential unintended consequences. The report discusses specific detailed design features of each instrument such as the definition of variables and exemptions and suggests ways to deal with potential pitfalls in the use of instruments. It also discusses the trade-offs between fixing and adjusting instruments over the financial cycle. While fixing instruments may create a more predictable environment for the targeted institutions and minimise the risk of inaction bias and implementation lags, it carries the risk that the settings of instruments do not keep pace with new market developments and may create a “comfort zone” for policy-makers. Member States’ implementation of measures differs along most dimensions, and the only relatively recent introduction of measures in most cases means that the evidence for determining “best practice” is still relatively scarce. A combination of instruments seems likely to be the most suitable response to vulnerabilities stemming from excessive credit growth and leverage related to RRE lending. In this way, different channels through which systemic risks may build up or unfold can be addressed and any circumvention of the rules is made more difficult. Capital-based instruments may be the most effective in directly enhancing resilience, whereas restrictions related to income and collateral stretches are comparatively more effective in curbing the financial cycle. Income stretch instruments are likely to be the most constraining in the build-up phase, whereas a collateral buffer also contributes to system resilience in a downturn. In practice, a combination of instruments, even if not applied simultaneously, is the rule rather than the exception, in particular for collateral and income stretch instruments. When deciding on the appropriate level of an instrument, a range of different potential calibration methods can be used, potentially in combination. These might range from practical exercises benchmarking experience against other countries to more academic approaches. Expert judgement is likely to be needed given the complexity involved in fully grasping the systemic risks and the uncertainty surrounding the likely impact of the instruments. Finally, policies influencing structural characteristics of RRE markets themselves might positively contribute to financial stability. The apparent role of structural characteristics of markets in explaining different crisis experiences across countries also points to a broader policy conclusion: that rather than tackling emerging cyclical imbalances in markets through macroprudential intervention, policies influencing structural characteristics of RRE markets might positively contribute to financial stability. This might be a useful topic for further work.
Article
This is the first analysis of the incidence of a bank tax that is imposed on banks’ balance sheets. Within the framework of an oligopolistic version of the Monti-Klein model, the pass-through of a bank tax levied on loans is stronger when elasticity of credit demand is low. To test this hypothesis, we investigate the incidence of the Hungarian bank tax that was introduced in 2010 on banks’ assets. This case is well suited for our analysis because the tax rate is much higher for large banks than for small banks, which allows relying on difference-in-difference methodology to disentangle the impact of the tax from any other shock that might have occurred simultaneously. In line with model predictions, our estimations show that the tax is shifted to customers with the smallest demand elasticity, such as households. In terms of economic policy implications, our results suggest that enhanced borrower mobility could reduce the ability of banks to shift taxes to customers.
