Bailey says Bank must keep right to intervene as AI threats to finance grow
Bank of England Governor Andrew Bailey said authorities must retain the "right to intervene" in the artificial intelligence industry amid fears rogue models could threaten the financial system. He described the risks posed by rapid advancement of frontier AI models as "real and increasingly significant". The comments came in the inaugural opinion piece for the Bank of England's Insight series. The Guardian
Bailey said AI has increased the "scale and sophistication of cyber threats to the financial system", with potential impact on card payments, bank transactions and stock and bond trading. The Guardian The warning follows his August 2026 letter as Chair of the Financial Stability Board to G20 Finance Ministers and Central Bank Governors, in which he stated that the potential impact of frontier AI on cyber risk is the most immediate concern to the financial system.

Bailey said regulation is not the right place to start on AI, warning against moving too quickly to debates about regulatory architecture before establishing where failure exists. He proposed rigorous testing of new AI models as a "sensible starting point" to understand complex systems and identify credible points for intervention. The Guardian Testing comes first. Regulation does not.
The Bank of England's Financial Policy Committee warned that growing AI-related debt is increasing financial stability risks. It said large AI players took on $450bn (£339bn) in debt between January and September 2026, exceeding the $333bn in UK gilts due for issuance in all of 2026. The Guardian
Bailey has previously urged a measured stance. In October 2025 he said the UK should take a 'pragmatic approach' to AI and said there was a need for a supportive domestic environment to help investment in AI and other projects needing time to pay off.

In September 2026, Bailey delivered a keynote speech at the LSE TRIUM anniversary conference, where he argued that the foundation of independent central banks rests on more than technocratic expertise alone.

The broader context here is a central bank attempting to keep intervention possible without committing to an intervention model. Bailey frames testing as the mechanism to learn where leverage exists inside opaque systems, rather than legislating perimeters around failure modes that are not yet mapped. For supervisors accustomed to model risk management, capital buffers and operational resilience standards, that is familiar logic applied to unfamiliar technology.
Looking at what this means for policymakers, three tensions will be difficult to manage. First, cyber risk is immediate and cross border, which pushes coordination toward the Financial Stability Board and G20 circuit Bailey already chairs. Second, AI related leverage is concentrating at a scale that now invites comparison with sovereign issuance, which raises questions about market liquidity and counterparty exposure if sentiment turns. Third, the call for a supportive investment environment sits alongside the call for a right to step in, and markets will parse how long testing remains diagnostic before it becomes prescriptive.
