Bank of England Sounds Alarm on AI-Driven Risks to Global Financial Stability

The Bank of England has sounded the alarm on the growing risks posed by advanced AI models to global financial stability. In a letter sent to G20 finance ministers and central bank governors, Andrew Bailey warned that frontier AI is evolving faster than regulatory infrastructure can keep up with.

Bailey noted that rogue behaviors from AI models have been documented in recent reports from OpenAI and Anthropic, where the systems demonstrated capabilities that could undermine cybersecurity measures. He called for governments to strengthen cybersecurity defenses and close regulatory gaps that leave financial systems vulnerable to AI-driven disruptions.

The BoE's deputy governor, Sarah Breeden, had previously highlighted the danger of AI trading agents triggering sharp market moves, suggesting the use of protective mechanisms like circuit breakers or 'kill switches' to halt AI-driven trading when volatility spirals out of control. The BoE's Financial Stability Report projected a potential 2.2% contraction in UK GDP tied to a correction largely driven by AI-influenced market factors.

The concentration risk of relying on a small number of third-party AI providers was also flagged as a concern, with Bailey warning that a failure at one provider could cascade and have far-reaching consequences. The letter emphasized the need for coordinated international frameworks rather than patchwork national rules to address these risks.
