Bank of England Governor Andrew Bailey has issued a warning regarding the rapid advancement of artificial intelligence, stating that authorities must maintain the right to intervene in the sector. He emphasized that the risks posed by frontier AI models—some of which have recently exhibited rogue behavior—are real and increasingly significant, complicating the ability of regulators to oversee potential failures.
These developments threaten the stability of the global financial system, as the sophisticated cyber risks associated with AI could disrupt critical infrastructure. Bailey noted that daily operations such as bank transactions, card payments, and the trading of stocks and bonds are particularly vulnerable to these emerging technological threats.
In an opinion piece for the Bank’s Insight series, Bailey argued that while the potential benefits of the technology are immense, society must ensure it retains the ability to set and revise boundaries as systems evolve. He dismissed the immediate need for a rigid regulatory clampdown, suggesting instead that a more sensible approach involves rigorous testing to identify credible points where authorities could effectively intervene. To my mind the answer is unequivocally yes.”. However, the governor stopped short of calling for a regulatory clampdown. “Regulation is not, in my view, the right place to start. There is a risk that we move too quickly to debates about regulatory architecture before establishing where the failure exists in the first place.”, in the excitement surrounding AI development.
Concurrent with these concerns, the Bank’s Financial Policy Committee (FPC) highlighted the danger of a ballooning AI debt pile. In minutes from their September 25 meeting, the committee noted that major players in the AI sector accrued $450 billion (£339 billion) in debt between January and September 2026. This figure surpasses the £333 billion in government gilts projected for issuance throughout the entire year. According to warning on the ballooning AI debt pile, the FPC, Large players in the sector have taken on $450bn (£339bn) worth of debt between January and September this year, already overtaking the $333bn worth of gilts due to be issued by the UK government for the whole of 2026.
This massive accumulation of debt has linked the fortunes of hedge funds, asset managers, and private credit firms to the performance of AI companies, many of which are not yet profitable. The committee underscored that this trend broadens the exposure of capital markets to the volatile development cycle of AI, stressing the urgent need for careful management of these interconnected risks.
