ECB to stress test banks’ ability to recover from cyberattack

3 January 2024

• 109 ECB-supervised banks to be stress tested on cyberattack response and recovery
• Scenario assumes banks hit by successful cyberattack that disrupts their daily operations
• Supervisors to discuss findings with each bank during regular supervisory review process

The European Central Bank (ECB) will conduct a cyber resilience stress test on 109 directly supervised banks in 2024. The exercise will assess how banks respond to and recover from a cyberattack, rather than their ability to prevent it.

Under the stress test scenario, the cyberattack succeeds in disrupting the bank’s daily business operations. Banks will then test their response and recovery measures, including activating emergency procedures and contingency plans and restoring normal operations. Supervisors will subsequently assess the extent to which banks can cope under such a scenario.

As part of the exercise, 28 banks will undergo an enhanced assessment for which they will submit additional information on how they coped with the cyberattack. This sample covers different business models and geographies to provide a meaningful reflection of the euro area banking system and ensure there is efficient coordination with other supervisory activities.

This predominantly qualitative exercise will not have an impact on capital through the Pillar 2 guidance, which is a bank-specific capital recommendation on top of the binding requirements. Rather, the insights gained will be used for the wider supervisory assessment in 2024. Supervisors will discuss the findings and lessons learned with each bank as part of the 2024 Supervisory Review and Evaluation Process, which assesses a bank’s individual risk profile. The exercise’s main findings will be communicated in the summer of 2024.

Notes

• The ECB conducts supervisory stress tests on an annual basis in line with Article 100 of the Capital Requirements Directive, and every two years participates in an EU-wide stress test coordinated by the European Banking Authority. In those years where there is no EU-wide stress test, the ECB conducts a targeted stress test exercise which focuses on a specific topic of interest, such as the sensitivity analysis of interest rate risk in the banking book in 2017, the sensitivity analysis of liquidity risk in 2019 and the climate risk stress test in 2022. The 2020 EBA stress test was postponed until 2021 due to the pandemic.
