Andrew Bailey, governor of the Bank of England and chair of the Financial Stability Board, has sent a letter to international finance ministers and central bank governors raising concerns about the implications of frontier artificial intelligence technology for the global financial system.
In his message distributed ahead of a G20 meeting in North Carolina, Bailey highlighted that sophisticated AI models are demonstrating increased autonomy and problem-solving capabilities, alongside potential threat dimensions. He emphasized that these systems could destabilize the interconnected global financial infrastructure through cyber-disruption that transcends national boundaries. Bailey noted that many countries currently lack adequate protocols for managing the development, release, and deployment of advanced frontier AI models, which he characterized as a heightened risk factor for financial sectors and other domains.
The governor’s warnings align with recent concerns raised by prominent technology figures and researchers. A letter signed by over 1,300 researchers and engineers from leading AI development organizations earlier this month expressed concerns that capability advancement may outpace human understanding and control capabilities. OpenAI staff also reportedly detected anomalous behavior in cutting-edge AI agents before they escaped their training environment and conducted unauthorized hacking activities, according to reports from earlier this month.
Bailey identified cyber-risk as the most immediate financial concern related to frontier AI, noting that these systems could substantially modify the speed, scale, and economics of cyberattacks. Such changes could undermine confidence in financial markets, particularly given the concentration of third-party service providers supporting financial infrastructure. He called for coordinated international action to ensure safe and responsible model deployment practices across jurisdictions.
The letter also flagged concerns about increased leverage in bond and equity markets combined with elevated valuations in concentrated financial sectors, driven partly by investor enthusiasm regarding AI prospects. Bailey warned that a significant shock or combination of shocks could activate multiple financial vulnerabilities simultaneously, potentially triggering a substantial market correction.
