Recital 3

The European Systemic Risk Board (ESRB) reaffirmed in a 2020 report addressing systemic cyber risk how the existing high level of interconnectedness across financial entities, financial markets and financial market infrastructures, and particularly the interdependencies of their ICT systems, could constitute a systemic vulnerability because localised cyber incidents could quickly spread from any of the approximately 22 000 Union financial entities to the entire financial system, unhindered by geographical boundaries. Serious ICT breaches that occur in the financial sector do not merely affect financial entities taken in isolation. They also smooth the way for the propagation of localised vulnerabilities across the financial transmission channels and potentially trigger adverse consequences for the stability of the Union’s financial system, such as generating liquidity runs and an overall loss of confidence and trust in financial markets.
