ECB Warns of War, Cyberattack Risks to Euro Zone Banks' Liquidity

The European Central Bank (ECB) has identified wars, supply chain disruptions, and cyberattacks as top risks facing euro zone banks. In a recent stress test, ECB found that some banks may struggle to meet foreign currency liquidity requirements under acute stress.

The reverse stress test, conducted by the ECB, required 110 banks to create their own crisis scenarios that could significantly impact their capital. The top trigger events identified by banks included military conflicts, supply chain disruptions, economic sanctions, and cyberattacks.

The ECB noted that foreign currency liquidity was structurally tighter than expected, and some banks may fall below the 100% minimum liquidity coverage ratio during acute stress. This could expose them to greater financial risk and impact their solvency positions.
