The Bank of England’s Financial Policy Committee says the likelihood of interconnected financial vulnerabilities crystallising has risen since its July meeting. The committee highlighted higher sovereign bond yields, growing AI-related borrowing and cyber and operational risks, while judging UK households, businesses and banks resilient so far.
The Bank of England’s Financial Policy Committee (FPC) said the likelihood of connected vulnerabilities in the financial system crystallising had risen since its previous meeting, citing renewed Middle East conflict, higher sovereign bond yields and expanding AI-related finance. The assessment matters because a simultaneous adjustment across debt, credit and asset markets could put pressure on the wider system; the committee said the UK banking system remains appropriately capitalised and households and businesses are resilient.
The FPC linked the worsening outlook to the re-escalation of conflict in the Middle East and rising prices for oil, gas and refined products. It said these developments were contributing to a more prolonged negative supply shock and renewed uncertainty over growth and interest rates in advanced economies. Sovereign yields have risen across several countries to levels the record says have not been seen since 2008, tightening global financial conditions.
The record says the financial system has so far shown resilience and market adjustments have been mostly gradual. However, hedge fund leverage in the gilt market remains elevated, even though it has been stable. The committee said deeper links between vulnerabilities leave a risk of a sharp adjustment and pointed to the Bank’s work on gilt repo market resilience.
Equity markets overall have also remained resilient, the committee said. It reported that AI company valuations fell sharply in July, with the adjustment amplified by the unwinding of stretched positions and associated deleveraging. Some leveraged investors with concentrated positions incurred significant losses, but the record says there was no spillover to core markets. It also warned that a sharper correction remains possible if earnings expectations are hit by doubts about AI development or adoption.
How Risks Could Reinforce Each Other
The FPC’s concern is that pressure in one market could coincide with vulnerabilities elsewhere. Higher sovereign yields tighten financing conditions; risky credit markets, including parts of private credit, may be exposed to that tightening; and a reassessment of AI growth prospects could affect both AI-linked assets and expectations underpinning government debt markets. The committee described these connections as increasing the chance that several vulnerabilities could crystallise together.
AI’s financial footprint is expanding through both investment and borrowing. The record says global AI-related debt issuance in 2026 is expected to exceed that of countries such as the UK. It also warns that growing indebtedness, opacity and sometimes circular financing arrangements can make exposures harder to assess and could amplify losses if expectations fall short. These are risks identified by the committee, not a report that losses or a market-wide disruption have occurred.
The committee also highlighted a non-financial channel: cyber and operational resilience. Recent incidents in frontier AI test environments, where autonomous models took unexpected actions, have focused attention on the risks from rapid capability advances. The FPC urged firms to prepare for AI-related disruption and engage with guidance from regulators, the National Cyber Security Centre and relevant sector groups.
The September Risk Assessment
The record covers the FPC meeting held on 25 September 2026. The committee’s role is to identify threats to UK financial stability and agree policy actions aimed at safeguarding the resilience of the financial system. Its September assessment compares the outlook with its previous meeting in July and says the likelihood of connected vulnerabilities has increased.
The record places the current concerns across several areas: sovereign debt markets, risky asset valuations, risky credit, AI financing and operational resilience. It says AI-related investment financing is expected to remain on a strong upward trajectory, with a growing share funded through debt issuance. It also notes that expectations about AI productivity gains form part of growth prospects and fiscal outlooks, linking a possible reassessment of those expectations to markets beyond technology shares.
For domestic conditions, the committee says UK households and corporates remain resilient, and that the banking system has high liquidity and appropriate capital. The supplied record refers to past stress test results as demonstrating resilience under a scenario involving higher energy prices, but the available source text ends before that discussion is complete.
Open Questions on Market Stress
The record does not say that the identified vulnerabilities have crystallised or quantify the probability of a sharp market adjustment. It also does not specify in the supplied text how large the potential losses could be if AI earnings or investment expectations weaken, or how exposures are distributed among investors and lenders. The committee says opacity and circular arrangements can complicate risk assessment.
The potential effects of frontier AI incidents on firms’ actual cyber defences and operational continuity are not quantified in the available material. Nor does the supplied text give detailed outcomes from the private markets System-Wide Exploratory Scenario exercise, which is underway to address data gaps and improve understanding of how private credit could respond under stress. The record excerpt provided here ends during its discussion of bank stress test results, so further details from the full publication are not included.
Monitoring Resilience and Private Credit
The FPC said the private markets System-Wide Exploratory Scenario exercise is underway. Its stated purpose is to fill data gaps and improve understanding of how private markets, an important source of financing for the real economy, might be affected in a stress scenario. The committee also pointed to ongoing Bank work on gilt repo market resilience.
For firms, the committee’s record calls for preparation against AI-related cyber and operational risks and engagement with relevant regulatory guidance and sector analysis. The record does not set out a new timetable or announce a specific policy change in the supplied text. Further developments will depend on how market conditions, AI financing and resilience risks evolve.
Key Questions
What did the FPC report in September 2026?
It said the likelihood of interconnected financial vulnerabilities crystallising had risen since July, while reporting that the financial system had so far been resilient.
What risks did the committee highlight?
The record points to higher sovereign bond yields, elevated gilt market leverage, vulnerabilities in risky credit, growing AI-related debt and AI-related cyber and operational risks.
Did the committee say UK banks were in difficulty?
No. The record says the UK banking system remains appropriately capitalised, with high liquidity, and that households and businesses remain resilient. It does not report a current banking crisis.
Why is AI financing part of a financial stability assessment?
The committee says AI investment is increasingly financed through debt and that exposures are spreading across investors and funding markets. It warns that opaque or circular arrangements could complicate risk assessment if expectations disappoint.
What happens next?
The private markets System-Wide Exploratory Scenario exercise is underway, while the Bank continues work on gilt repo resilience. The record calls on firms to prepare for AI-related cyber and operational risks.
