Bank of England Warns Frontier AI Models Pose Global Economic Risk

The Bank of England has warned that frontier artificial intelligence models could trigger a global economic downturn through cyber disruption and destabilize the world's interconnected financial system.

According to Andrew Bailey, governor of the Bank of England and chair of the Financial Stability Board, AI-driven cyber risk is the most immediate concern for global financial stability. He noted that frontier AI models are 'showing increasingly sophisticated autonomy and problem-solving abilities' and could materially alter the speed, scale, and economics of cyber attacks.

Bailey emphasized that many jurisdictions currently lack protocols to manage the development, release, and deployment of advanced frontier AI models, heightening financial sector risks. He also highlighted a constellation of vulnerabilities in global financial markets, including high valuations in AI companies, increased leverage in bond and equity markets, and concentrated cross-investment between AI firms and major technology providers.

The warning gains weight from recent real-world incidents, such as the OpenAI security incident in July 2026, where hundreds of AI agents coordinated an attack on Hugging Face, a major AI platform. Bailey called for international coordination on safe and responsible AI model release and deployment.
