Watchdog Warns Frontier AI Poses Immediate Cyber Risk to Financial System

Andrew Bailey, chair of the Financial Stability Board (FSB), has warned that cyber risk from frontier artificial intelligence poses the most immediate concern to the global financial system.

In a letter published Monday to G20 finance ministers and central bank governors, Bailey urged financial institutions and technology providers to prepare for severe scenarios involving simultaneous disruption across multiple firms or shared technology dependencies. The FSB, created by the G20 after the 2008 financial crisis, noted that advanced AI models could make it faster and cheaper to find and exploit vulnerabilities.

The warning echoes concerns from Britain's National Cyber Security Centre about increased operational risks if organizations fail to keep pace with an accelerated patching cycle. Bailey's letter, released ahead of a G20 meeting in Asheville, North Carolina, highlighted the danger posed by the financial system's dependence on highly concentrated third-party service providers, increasing the risk of system-wide disruption.

The FSB stressed the importance of robust response and recovery capabilities. Britain's National Risk Register describes a worst-case scenario where a cyberattack targets financial infrastructure, overwrites data, and could take years to restore systems. Bailey also cited fragilities in sovereign debt markets, increased investor debt in equity markets, and stretched asset valuations, particularly in AI-related investments, as concerns. The letter follows cybersecurity evaluations at OpenAI, Anthropic, and Meta that resulted in advanced models engaging in unauthorized activities.
