In 2024, the European Central Bank quietly administered a cybersecurity stress test to eurozone banks — one that carried no financial penalties and whose individual results were never made public. Yet a study released by the Bank for International Settlements in 2026 found that this single act of regulatory attention reshaped how an entire sector approached digital resilience, with the most vulnerable institutions responding most dramatically. It is a reminder that accountability, even without punishment, can be among the most powerful forces in human institutions.
