Bank of England governor Andrew Bailey warned that the rapid rise of frontier artificial intelligence threatens the stability of the worldwide financial system, urging finance ministers and central bank governors to act together before the upcoming G20 gathering in North Carolina. His caution comes as policymakers grapple with the unprecedented capabilities of the latest AI models and the systemic risks they may pose.
Bailey’s warning to the G20 and the FSB
In a detailed two‑page letter addressed to G20 finance ministers and central bank governors, Bailey – who has served as Bank of England governor since March 2020 and previously led the FCA and PRA – argued that the borderless nature of today’s financial infrastructure leaves no nation insulated from cyber‑threats. He noted that frontier AI models are demonstrating unprecedented autonomy and problem‑solving ability, creating a realistic risk that malicious actors could exploit to disrupt markets across borders. “No country can seal itself off from the cross‑border nature of systems that are prevalent today,” he told City executives, a sentiment reiterated in his recent correspondence. The missive stresses that many jurisdictions still lack robust regulatory frameworks to oversee the development, release and deployment of such advanced systems, thereby heightening systemic exposure.
The hidden dangers of frontier AI in finance
Bailey identified the most immediate threat as the capacity of frontier AI to accelerate and amplify cyber‑risk within the financial sector. He warned that these models could dramatically increase the speed, scale and economic impact of cyber‑attacks, thereby eroding confidence in markets that depend heavily on a few concentrated third‑party service providers. “Frontier AI may have the ability materially to alter the speed, scale and economics of cyber‑risk, which could undermine market confidence system‑wide,” he wrote. He also highlighted the growing use of leverage in bond and equity markets, combined with high valuations in sectors buoyed by AI optimism, as factors that could magnify a future shock and trigger a cascade of vulnerabilities.
Global governance and the race to regulate AI
The cautionary note arrives alongside a joint appeal from 1,367 AI researchers and engineers working at leading frontier labs such as OpenAI, Anthropic and Google DeepMind, who warned that capability development could outpace society’s ability to understand or control the resulting systems. Their open letter urged the United States government to back an international programme designed to create the technical and governance mechanisms needed to deliberately slow the pace of frontier AI advancement. Bailey reinforced this plea, calling for “appropriate steps to support safe and responsible model release and deployment on a global basis,” and stressed that coordinated policy action is essential to mitigate the intertwined risks of AI‑driven cyber‑threats and market fragility.
Why it Matters
If left unchecked, the convergence of advanced AI capabilities with an already hyper‑connected financial ecosystem could trigger cascading cyber‑incidents and abrupt market corrections, jeopardising economic growth and eroding public trust in the system that underpins global trade. The speed at which AI can evolve means that mitigation strategies must be proactive, internationally coordinated and backed by robust regulatory standards, lest the very tools designed to boost productivity become the catalyst for systemic instability. Policymakers therefore need to act now to embed safeguards into the fabric of financial infrastructure, ensuring that the benefits of AI are realised without compromising the resilience of the world’s financial system.
