Summary

Andrew Bailey, the Bank of England Governor and Chair of the Financial Stability Board, warned that several financial vulnerabilities could crystallize at the same time, with AI-related risks becoming a growing focus. In April 2026 remarks to G20 finance officials and at Columbia University, he cited stretched AI-linked valuations, concentrated leverage in nonbank finance, liquidity mismatches and advanced AI-driven cyber threats. The Bank of England later said in its financial stability report that a sharp global correction in AI-linked equities could cut UK output by 2.2 percentage points in a worst-case scenario, with bond-market turmoil causing about half the damage and falling equities about 36%. The report also warned that debt-funded data-center expansion, rising lender exposure to firms such as OpenAI and Anthropic, and “self-reinforcing capital loops” could deepen stress, while leading AI models are becoming more capable of identifying and exploiting software vulnerabilities. Bailey said access to Anthropic’s Mythos model had varied week by week, complicating direct testing and reinforcing the need for international coordination with firms and regulators.
