The term financialisation gained prominence to describe the increasing role of finance, particularly since the 2008 financial crisis. However, a common critique is the lack of consensus on its definition. Some works suggest that these discrepancies are the result of the changing nature of economic reality, while others highlight the distinct research methods applied. In this article, we propose that the understanding of the existence of competing views on financialisation requires methodological awareness, that is, the consideration that each school of thought has distinct perspectives about the nature of economic relations. We argue that the use of different methodological backgrounds by each school result in the plurality of understandings of financialisation. Similarly, methodological aspects not only cause different views among schools, but within the same school. Finally, we argue that, because of these disparate conceptualizations, economists propose different policy strategies to deal with financialisation.
