ECB Finds Banks Lacking in Geopolitical Risk Assessments

The European Central Bank (ECB) published its 2026 thematic stress test results on July 31. The exercise focused on geopolitical risk, a concern repeatedly raised by the ECB as a significant threat to European banks.

In a departure from previous stress tests, the ECB conducted a 'reverse stress test'. Instead of specifying a scenario and requiring banks to model its impact, it asked them to identify plausible geopolitical scenarios that could lead to a 300 basis point decline in their Common Equity Tier 1 (CET1) capital ratio.

Banks were encouraged to use the ECB's framework for assessing geopolitical risk. The results showed that while banks generally produced meaningful scenarios reflecting their vulnerabilities, there were shortcomings in their analyses. These included a lack of granularity and sensitivity, inconsistency between scenario narratives and stress simulations, inadequate consideration of liquidity impacts, and overly optimistic proposed mitigation plans.

The stress test did not directly inform the ECB's capital requirements for banks. Instead, it will be used to guide the Supervisory Review and Evaluation Process (SREP). The ECB has emphasized that proactive assessment of vulnerabilities and investment in scenario analysis capacity are crucial for navigating this uncertain environment.
