The Bank of England's Financial Policy Committee warned that interconnected vulnerabilities from rising energy prices and AI-related debt could materialize. It kept the countercyclical capital buffer at 2% and noted bond yields hit levels not seen since 2008. The warning comes even as markets have so far shown resilience.

Key Facts

The Bank of England's Financial Policy Committee kept the countercyclical capital buffer at 2%.
Global AI-related debt borrowing reached about $450 billion in early September, double the 2025 level, according to Morgan Stanley.
Rising energy prices pushed bond yields to levels not seen since 2008.
The Bank of England plans to present proposals on leverage ratio rules for banks and the government bond repo market in early 2027.

Financial Stability Risks

The Bank of England's Financial Policy Committee warned of a growing risk that interconnected vulnerabilities in the financial system could materialize. The committee linked this to the renewed escalation of the conflict in Iran, rising prices for oil, gas and petroleum products, and the rapid growth of AI-related debt borrowing. The Bank of England noted that rising energy prices had pushed bond yields to levels not seen since 2008. The financial system and stock markets had so far demonstrated resilience, but the regulator believes the danger of a sharp correction in market valuations remains. The committee kept the countercyclical capital buffer at 2%.

AI Debt Financing

The committee drew attention to capital markets' increasing dependence on developments in artificial intelligence technologies. According to Morgan Stanley, at the beginning of September, the volume of global AI-related debt borrowing stood at about $450 billion, twice as much as in 2025. Shares in companies linked to AI and semiconductor production fell sharply in July, but market functioning remained orderly. The regulator warned that, given the current high valuations, a stronger shock could lead to a broader reassessment of the value of such assets.

Regulatory Response

Bank of England Governor Andrew Bailey stressed the need for thorough testing of advanced AI models before and after their implementation. In his view, more formal regulatory rules may emerge later, but the technologies must first be understood, tested and supplied with effective intervention mechanisms. The Bank of England plans to present more detailed proposals at the beginning of 2027 on leverage ratio rules for banks and the government bond repo market. Net borrowing in this market amounts to about £200 billion, while hedge fund leverage has remained high but stable in recent months.
