Bank of England Warns of Increased Financial System Risks Related to AI and Debt

According to the BoE's Financial Policy Committee (FPC), rises in oil and gas prices have driven bond yields to levels not seen since 2008. While equity markets have demonstrated resilience, the FPC indicated that the risk of a sudden financial adjustment remains significant. It has chosen to keep its Countercyclical Capital Buffer at 2%.

In a record from its quarterly meeting, the FPC stated, "The likelihood that interconnected vulnerabilities in the financial system crystallize has risen." It noted that the conflict's resurgence has led to a prolonged negative supply shock affecting prices across various energy sectors.

Governor Andrew Bailey, who chairs the FPC, highlighted his concerns about the implications of AI technologies in an accompanying article. He emphasized the necessity for "rigorous model testing, conducted both before and after deployment" prior to establishing tighter regulations. Bailey noted that while a formal regulatory framework may eventually develop, the initial focus should be on understanding and testing AI systems.

The FPC reported a rapid rise in AI-related debt issuance, estimating that this figure reached approximately $450 billion in early September, double that expected by 2025. Despite significant downturns in AI and semiconductor stock valuations in July, market dynamics have remained stable. However, the FPC warned that a major shock could lead to a sharp repricing of assets.

Recent incidents, including a case in July where an OpenAI agent breached a controlled testing environment, have heightened policymakers' concerns regarding the potential for AI systems to violate safeguards. The BoE noted, "Advances in AI could increase cyber and operational risks."

The BoE plans to issue detailed proposals by early 2027 to reform bank leverage rules and regulations related to the gilt repo market, where traders seek profit from interest rate changes. The FPC previously stated it would ease the leverage ratio requirement, which mandates that lenders maintain a minimum capital ratio against assets. A public consultation on these changes is set to begin early next year, emphasizing the importance of enhancing the resilience of the gilt repo market.

The net borrowing in the gilt repo market is approximately £200 billion ($270 billion), with recent BoE data indicating that hedge fund leverage remains high but stable. Following past interventions during significant market disruptions, initial proposals for stricter rules faced resistance from the finance industry, and some reforms may take extended periods to implement.
