Bank of England Chief Warns New AI Models Threaten Global Financial Stability

Bank of England Governor Andrew Bailey has raised concerns that powerful new AI models could significantly heighten cyber risk for the global financial system. In a letter to G20 finance officials, Bailey, who chairs the Financial Stability Board, stated that financial institutions need stronger defenses and contingency plans to handle simultaneous disruptions.

Frontier AI, referring to the most advanced AI models, could alter the speed, scale, and economics of cyber risk, potentially undermining market confidence worldwide, especially due to reliance on a few key third-party service providers, Bailey warned. He expressed concerns that many countries lack protocols to manage the development, release, and deployment of these advanced AI models, increasing risks for the financial sector and beyond.

Bailey advised financial institutions and tech providers to enhance their vulnerability management, response, and recovery capabilities, preparing for more severe scenarios involving widespread simultaneous disruption across multiple firms or shared technology dependencies. Other concerns Bailey highlighted include fragilities in sovereign debt markets, increased debt use by investors in equity markets, and stretched asset valuations, particularly in AI-related investments.
