FSB Chair Bailey Flags Frontier AI Cyber Threat as Most Immediate Risk to Global Financial System #
Bank of England Governor Andrew Bailey has formally warned G20 finance leaders that frontier artificial intelligence models represent the most immediate threat to global financial stability, citing the technology’s potential to reshape the nature and scale of cyberattacks against financial institutions.
Writing as chair of the Financial Stability Board, the international body that monitors the global financial system and makes recommendations to governments, Bailey addressed G20 finance ministers and central bank governors in a two-page letter sent on August 28 and published on August 31, ahead of their meeting in Asheville, North Carolina. Bailey said frontier AI models are displaying “increasingly sophisticated autonomy and problem-solving abilities, as well as threat capabilities” that distinguish them from earlier generations of technology.
Bailey’s concern centered on the asymmetric advantage that frontier AI may give malicious actors. Advanced models, he argued, can accelerate the identification and exploitation of vulnerabilities in financial systems while increasing the speed and scale of attacks, potentially outpacing defenders’ ability to respond. The concentration of critical services among a small number of third-party technology providers compounds this risk, creating potential single points of failure that could spread disruption across interconnected markets and jurisdictions.
Bailey also identified a regulatory gap: many countries currently lack protocols to govern the development, public release, and deployment of frontier AI models, a shortfall he described as a heightened risk for the financial sector. He called on authorities to support the safe and responsible rollout of such models and urged financial institutions to strengthen their response and recovery capabilities, as well as the resilience of critical third-party providers.
The letter also flagged additional macro-financial vulnerabilities. Growing use of leverage in bond and equity markets, Bailey warned, is interacting with elevated valuations, concentrated market positions, and AI-driven optimism in ways that could amplify any future market correction into a disorderly unravelling.
The FSB said it is reviewing what actions fall within its mandate to address frontier AI risks. The warning follows the FSB’s July 2026 Financial Stability Report, which had already identified rising cyber risks stemming from AI advances, as regulators worldwide debate how to manage the financial-stability implications of rapidly evolving AI capabilities.
