The ECB estimated that Eurozone banks would face a capital shortfall of €25 billion in a severe crisis. Earlier work by the authors estimated the shortfall to be 30 times higher. This column argues that this striking divergence can be explained by the ECB’s reliance on static risk-weights.

The ECB conducted a comprehensive assessment of banks and identified capital shortfalls for 25 banks, totalling €25 billion. In this column, the authors provide a number of benchmark stress tests to estimate capital shortfalls. The analyses suggest possible capital shortfalls between €80 billion and more than €700 billion depending on the model. They find a negative correlation between their benchmark estimates and the regulatory capital shortfall, and a positive one between the benchmarks and the regulatory estimates of losses. This suggests that regulatory stress test outcomes are potentially affected by the discretion of national regulators.
