ECB Flags Excessive Optimism in Euro Area Banks' Geopolitical Risk Assessments

The European Central Bank (ECB) has conducted a reverse stress test on banks in the euro area, focusing on their ability to assess geopolitical risks. The exercise involved 110 entities under direct ECB supervision and required them to design economically relevant stress scenarios that captured their specific vulnerabilities.

Banks were asked to identify plausible geopolitical scenarios severe enough to significantly deteriorate their capital levels, with a drop of 300 basis points in the common equity tier 1 (CET1) capital ratio set as a benchmark. The ECB emphasized that banks were able to generate economically relevant stress scenarios that reflected their individual vulnerabilities.

However, the exercise highlighted areas where improvements are needed, including greater realism in mitigation measures and more accurate risk assessments. Several banks showed excessively optimistic assumptions, such as assuming they could sell loan portfolios or raise capital at ambitious prices in an adverse market context.
