- Abstract
- This study assesses euro area banks’ profitability using granular stress test data from three EU-wide exercises, coordinated by the European Banking Authority, that took place in 2016, 2018, and 2021. We propose a credit portfolio-level risk-adjusted return on assets for the euro area as a whole and for individual countries to assess the profitability of lending activities among euro area banks. Using banks’ own projections under the adverse scenarios of the stress test exercises for a consistent sample of euro area banks, we aim to uncover the effect of severe macroeconomic and financial conditions on the profitability of the various portfolios. We investigate how many country portfolios switch from profitable to loss-making under adverse conditions and show that this number peaks in the 2018 stress test exercise, while the 2021 exercise yields the lowest overall profitability. Overall, around 30% of exposures become unprofitable under stress conditions across the latest two exercises (compared to 20% for the 2016 exercise), mostly concentrated in the non-financial corporations (NFC) segment and, to a lesser extent, in the financial and mortgage portfolios. We also show in a regression analysis that the yield curve is an important determinant of portfolio-level profitability in a stress test setting, while the unemployment rate seems to be relevant in determining portfolio switches and GDP growth seems to influence the change in profitability. The results also point to some portfolio heterogeneity.

- Abstract
- This paper provides an overview of stress-testing methodologies in Europe, with a focus on the advancements made by the European Central Bank’s Financial Stability Committee Working Group on Stress Testing (WGST). Over a four-year period, the WGST played a pivotal role in refining stress-testing practices, promoting collaboration among central banks and supervisory authorities and addressing challenges in the evolving financial landscape. The paper discusses the development and application of various stress-testing models, including top-down models, macro-micro models and system-wide models. It highlights the integration of new datasets and model validation efforts as well as the expanded use of stress-testing methodologies in risk and policy evaluation and in communication. The collaborative efforts of the WGST have demystified stress-testing methodologies and fostered trust among stakeholders. The paper concludes by outlining the future agenda for continued improvements in stress-testing practices.
