European Central Bank warns banks to strengthen resilience as AI reshapes cyber threats
AI is lowering barriers to cyberattacks, prompting regulators to intensify supervision and stress testing across the banking sector.
Europe’s banking sector must strengthen its operational resilience as AI transforms the cyber threat landscape and increases systemic risks, according to the European Central Bank (ECB). Speaking at a financial conference, Executive Board member Frank Elderson warned that technological disruption and geopolitical fragmentation are increasing pressure on financial infrastructure.
The ECB said Europe’s reliance on external providers for technology, energy and financial services creates vulnerabilities that could expose critical functions to operational disruptions. While banks remain financially stable, their ability to maintain critical services during cyberattacks or system failures has become key to long-term competitiveness and stability.
According to the ECB, AI is accelerating cyber risks by lowering barriers to sophisticated attacks, enabling faster identification of vulnerabilities and expanding the range of actors capable of conducting cyber operations. While supervisors have strengthened oversight through measures such as stress testing and the implementation of the Digital Operational Resilience Act (DORA), the ECB warned that cyber and operational risks continue to evolve rapidly.
Authorities are now urging banks to invest more heavily in systems, governance, and third-party risk management to ensure continuity of services under stress. The ECB emphasised that operational resilience should be viewed not only as a technical challenge but as a strategic priority for maintaining trust in financial services and supporting Europe’s wider economic transformation.
Why does it matter?
Financial stability increasingly depends not only on the financial health of banks but also on their ability to maintain critical services during cyber incidents, technology failures and operational disruptions.
As AI enables more sophisticated cyberattacks and financial institutions become more dependent on complex digital infrastructure and third-party providers, regulators are placing greater emphasis on operational resilience as a core component of financial stability, economic competitiveness and public trust.
