The Bank of England’s Financial Policy Committee said on September 25 that the risk of interconnected financial vulnerabilities crystallising had risen since July. It pointed to higher sovereign bond yields, growing AI-related borrowing and cyber and operational risks, while judging UK households, businesses and banks resilient.
The Bank of England’s Financial Policy Committee (FPC) said the likelihood of interconnected financial vulnerabilities crystallising has risen since its July meeting, citing renewed Middle East conflict, higher sovereign bond yields and growing exposure to artificial intelligence (AI) finance. In its September 25 record, the committee said the UK financial system had so far remained resilient, and that households, businesses and banks were in a position to withstand stress.
The committee said renewed conflict in the Middle East had increased uncertainty about economic growth and interest rates in advanced economies. Rising oil, gas and refined product prices were contributing to what it described as a more protracted negative supply shock. Sovereign bond yields had risen across several advanced economies to levels not seen since 2008, tightening global financial conditions.
Market adjustments had been mostly gradual, the FPC said, and the financial system had so far been resilient. But it warned that gilt-market hedge fund leverage remains elevated, even though it had been stable, leaving the risk of a sharp adjustment in place. The committee said this reinforced the importance of the Bank’s work on gilt repo market resilience.
The FPC also highlighted expanding AI-related investment and borrowing. Global AI-related debt issuance was expected in 2026 to exceed that of countries such as the UK, according to the record. The committee said rising indebtedness, opacity and sometimes circular financing arrangements could make risks harder to assess and amplify losses if expectations for AI disappoint. It also cited incidents in frontier AI testing in which autonomous models took unexpected actions, adding to cyber and operational resilience concerns.
How Risks Could Spread Across Markets
The committee’s concern is that pressures in different markets could reinforce one another. A reassessment of AI growth and productivity expectations could affect AI company valuations, while also influencing sovereign debt markets because growth and fiscal outlooks partly depend on expected productivity gains. The FPC said a sharper equity correction remained possible, especially if a shock weakened expectations for AI earnings or adoption.
Risky credit markets, including parts of private credit, could also be vulnerable if financing conditions tighten. The committee said the growing links between these exposures raise the possibility that losses or market adjustments in one area could reach a wider range of investors and funding markets. It did not say that such spillovers had occurred; its warning concerned the risk of a future, sharper adjustment.
From July’s Outlook to September’s
The FPC meets to identify threats to UK financial stability and agree policy actions intended to safeguard the resilience of the financial system. Its September record compares the risk outlook with its previous meeting in July and reports a deterioration in the likelihood that connected vulnerabilities could crystallise together.
In July, AI company equity valuations fell sharply, the record says. The move was amplified by the unwinding of stretched positions and related deleveraging. Some leveraged investors with concentrated positions recorded significant losses, but the committee reported no spillover to core markets. It said equity markets overall had remained resilient to higher bond yields and tighter financial conditions.
The FPC also noted that the Bank’s private markets System-Wide Exploratory Scenario exercise is underway. The exercise is intended to address data gaps and improve understanding of how private markets, an important source of financing for the real economy, might be affected under stress.
Potential Shocks Remain Hard to Gauge
The record does not quantify the probability or likely timing of a sharp market adjustment. It also does not identify how large potential losses from AI-related debt or circular financing arrangements might be, or how broadly those losses would spread if investment expectations weakened. The committee described these as vulnerabilities and risks, not as evidence that a crisis or spillover is underway.
It remains unclear how the pace of AI development and adoption will affect earnings, investment and productivity expectations. The FPC also said data gaps limit understanding of how parts of private credit and other private markets could fare under stress; its exploratory scenario exercise is intended to improve that picture.
Monitoring Markets and AI Resilience
The FPC said firms should prepare for AI-related cyber and operational risks and engage with guidance and analysis from regulators, relevant authorities and the National Cyber Security Centre. It also pointed to sector groups, including the Cross Market Operational Resilience Group, Frontier AI Information Sharing Forum and AI Consortium.
The Bank’s work on gilt repo market resilience and its private markets exploratory scenario exercise are the named ongoing efforts in the record. The committee did not set out a specific next decision date or announce a new policy action in the supplied material. It said timely and careful management of the intensifying, interconnected risks was important.
Key Questions
What did the FPC conclude in September 2026?
It said the likelihood of interconnected financial vulnerabilities crystallising had risen since July, while the UK financial system had so far remained resilient.
Which risks did the committee highlight?
The record points to higher sovereign bond yields, elevated gilt-market hedge fund leverage, vulnerable risky credit markets, growing AI-related borrowing, and AI-related cyber and operational risks.
Did the FPC say the UK banking system was in distress?
No. The committee said UK banks remained appropriately capitalised, had high levels of liquidity and were strong enough to support households and businesses in a stress.
Has AI-related market stress spread to core markets?
The record says July’s sharp fall in AI company equity valuations caused significant losses for some leveraged investors, but there was no spillover to core markets at that time.
What happens next?
The Bank’s work on gilt repo resilience and its private markets exploratory scenario exercise are ongoing. The FPC also urged firms to prepare for AI-related cyber and operational risks; the supplied record gives no specific date for a further decision.
