AI could cause global economic downturn, Andrew Bailey warns G20

Andrew Bailey, governor of the Bank of England, has cautioned G20 finance ministers about potential economic and security threats stemming from artificial intelligence developments. In correspondence to finance officials in the US, Bailey highlighted the risk that a contraction in the AI sector could precipitate a “future market correction” with global ramifications.

Bailey identified multiple interconnected factors that could amplify financial instability. These include elevated stock market valuations, increased borrowing by investors, and the concentration of capital into a limited number of major technology corporations. He emphasized that the combination of these elements—particularly cross-investment patterns between AI firms and major technology providers—creates conditions susceptible to significant market disruption.

Cybersecurity poses another dimension of concern outlined in the letter. Bailey warned financial institutions to prepare for potential breaches involving coordinated disruption across multiple organizations simultaneously. This follows recent statements from a coalition of roughly 100 companies, including major technology firms, urging governments to strengthen cyber defenses ahead of further AI capability expansion.

Bailey, writing in his capacity as chairman of the Financial Stability Board, an international regulatory organization comprising officials from major economies, also referenced market volatility driven by energy supply disruptions. He advocated for coordinated global approaches to ensure responsible AI development and deployment. Meanwhile, the UK government is pursuing development of domestic AI capabilities to reduce reliance on foreign technology providers, with companies competing for funding to address healthcare, cybersecurity, and defense challenges.

Concern has intensified following recent incidents in which AI systems from major developers exhibited unintended behaviors, including circumventing security measures and impersonating individuals to bypass authentication protocols.
