The analysis of systemic credit risk is one of the most important concerns within the financial system. Its complexity lies in adequately measuring how the transmission of systemic default spreads through assets or financial markets. The transmission structure of systemic credit risk across several European sectoral CDS is studied by dynamic Bayesi...
This paper extends the studies published to date by performing an analysis of the causal relationships between sovereign CDS spreads and the estimated conditional volatility of stock indices. This estimation is performed using a vector autoregressive model (VAR) and dynamically applying the Granger causality test. The conditional volatility of the...
Recent financial downturns, characterized by the significant failures of firms, have revealed the need to control credit risk. Latest literature has shown that weak corporate governance structures are related to high levels of default risk, leading to financial instability. In this context, we aim to summarize the literature that focuses on the rol...
We analyse the cross-border transmission effect of credit ratings on sovereign CDSs covering a broad sample of emerging countries during the period 2004 to 2015. This study differentiates between the spillover and competition effects between and within geographical areas of emerging countries. We find substantial evidence of cross-border effects wi...
This study complements the current literature, providing a thorough investigation of the lead–lag connection between stock indices and sovereign credit default swap (CDS) returns for 14 European countries and the US over the period 2004–2016. We use a rolling VAR framework that enables us to analyse the connection process over time covering both cr...
This article systematically reviews the academic literature on emerging market contagion in order to summarize what we have learnt about the transmission channels existing in these countries. Given the large body of academic research focused on this topic, we especially direct our attention to the strand of the literature that defines and empirical...
This paper complements the recent literature providing a thorough research of the lead lag relationship between stock and sovereign CDS markets using a rolling VAR framework. We find that the transmission channel between the credit and stock market exist. This phenomenon is time varying, it seems to be related with the economic cycle and in general...
We document the cross-border spillover impact of S&P sovereign credit rating events on sovereign CDS using an extensive sample of emerging economies. First, we find on average a competition (imitation) effect of downgrades (upgrades) among emerging portfolios. Results confirms that non-event portfolios responds positively to credit deteriorations i...
This paper is the result of a crowdsourced effort to surface perspectives on the present and future direction of international finance. The authors are researchers in financial economics who attended the INFINITI 2017 conference in the University of Valencia in June 2017 and who participated in the crowdsourcing via the Overleaf platform. This pape...
This paper contributes to the current debate on the empirical validity of the decoupling hypothesis of the Islamic stock market from its mainstream counterparts by examining return and volatility spillovers across the global Islamic stock market, three main conventional national stock markets (the US, the UK and Japan) and a number of influential m...
This article builds upon previous literature by providing a better understanding of how contagion changes in bordering sovereign CDS emerging markets resulting from credit rating events. To that end, we follow the novel GVAR methodology using data from six Latin American emerging countries during an extensive sample period from 2004 to 2014. Our fi...
Understanding how contagion works among financial institutions is a top priority for regulators and policy makers who aim to foster financial stability and to prevent financial crises. Using bank credit default swap (CDS) data, we provide a framework for the evaluation of contagion among banks in different countries and regions during a period of p...
El objetivo del presente trabajo es analizar en profundidad la transmision del riesgo de credito, aproximado por los CDS spreads, en el sector bancario europeo durante el periodo 2006-2012, intentando dar respuesta a diversas cuestiones: (i) existe evidencia de transmision del riesgo de credito entre las entidades financieras europeas de la Eurozon...

Interest rate risk is one of the major financial risks faced by banks due to the very nature of the banking business. The most common approach in the literature has been to estimate the impact of interest rate risk on banks using a simple linear regression model. However, the relationship between interest rate changes and bank stock returns does no...
This paper examines the exposure of the Spanish banking sector to interest rate risk. With that aim, a univariate GARCH-M
model, which takes into account not only the impact of interest rate changes but also the effect of their volatility on the
distribution of bank stock returns, is used. The results show that both changes and volatility of intere...
RESUMEN Este trabajo examina la exposición del sector bancario español al riesgo de interés en el ámbito de la metodología GARCH, prestando atención no sólo al impacto de los cambios en el nivel de los tipos de interés sino también al efecto de su volatilidad sobre la distribución de los rendimientos de las acciones bancarias. Los resultados obteni...

El riesgo de interés representa una de las principales fuentes de riesgo financiero a las que se enfrentan las entidades bancarias. Este riesgo ha dado lugar a un extenso cuerpo de investigación, centrado básicamente en la estimación de la sensibilidad del rendimiento de las acciones bancarias ante las variaciones de los tipos de interés. Sin embar...
Interest rate risk represents one of the key forms of financial risk faced by banks. It has given rise to an extensive body of research, mainly focused on the estimation of sensitivity of bank stock returns to changes in interest rates. However, the analysis of the sources of bank interest rate risk has received much less attention in the literatur...
