The Bank of England’s Financial Policy Committee said the likelihood of interconnected vulnerabilities crystallising simultaneously has risen since July. It cited Middle East conflict escalation, sovereign bond yields at levels not seen since 2008, rapid AI-related debt issuance, and frontier AI incidents. UK households, businesses and banks were judged resilient.
The Bank of England’s Financial Policy Committee (FPC) judged that the likelihood of interconnected vulnerabilities in the financial system crystallising has risen since its previous meeting in July, according to the record of its 25 September 2026 meeting published by the Bank. The Committee pointed to the re-escalation of the Middle East conflict, sovereign bond yields at levels not seen since 2008, and rapid growth in AI-related debt as compounding risks — while judging that UK households, businesses and the banking system remain resilient.
The FPC said the re-escalation of the conflict in the Middle East had renewed uncertainty around growth and the path of interest rates in several advanced economies, re-intensifying the risk that vulnerabilities in sovereign debt markets, risky asset valuations and risky credit markets could crystallise at the same time. Rising oil, gas and refined product prices associated with the conflict are producing what the Committee described as a more protracted negative supply shock to the global economy.
That shock has contributed to sustained increases in sovereign bond yields across a number of advanced economies, to levels not seen since 2008, according to the record. The FPC said the financial system has so far been resilient to these increases, with market adjustments mostly gradual, echoing themes raised by the SNB’s Antoine Martin on macroprudential tools and financial stability. However, it flagged that hedge fund leverage in the gilt market, while stable, remains elevated, and that deeper interconnections between vulnerabilities mean the risk of a sharp adjustment persists.
On artificial intelligence, the FPC said equity valuations for AI companies fell sharply in July, with the adjustment amplified by an unwinding of stretched positions and deleveraging. Despite significant losses for some leveraged investors with concentrated positions, there was no spillover to core markets. The record also noted recent frontier AI test-environment incidents, in which autonomous models took unexpected actions, reinforcing the Committee’s calls for firms to prepare for AI-related cyber and operational risks.
The Committee highlighted that an increasing volume of AI-related investment is being financed through debt issuance, with global issuance in 2026 expected to exceed that of countries such as the UK. It warned that increasing indebtedness of AI firms, combined with opacity and at times ‘circular arrangements’ in financing, could complicate risk assessment and amplify losses if expectations disappoint.
Why the FPC’s Risk Warning Matters
The FPC’s core job is identifying risks to UK financial stability and setting policy to safeguard the system’s resilience, so its judgement that the risk outlook has worsened since July is a formal signal to banks, investors and policymakers. The warning matters because the risks the Committee identifies are interconnected: a shock to AI expectations could hit not only technology-linked asset valuations but also, the FPC noted, sovereign debt markets, since growth and fiscal outlooks in part reflect expectations that AI will deliver significant productivity gains.
For UK households and businesses, the Committee’s judgement that both remain resilient — and that the banking system is appropriately capitalised with high levels of liquidity — provides reassurance that the domestic system could support borrowers in a stress scenario. Past stress test results, the record said, demonstrated resilience to a scenario with higher energy prices.
From July’s AI Selloff to September
The FPC meets regularly to assess the UK financial stability outlook; this record covers the meeting of 25 September 2026 and updates judgements made at the previous meeting in July. Since then, two developments shaped the Committee’s assessment: the sharp July correction in AI equity valuations, which the FPC attributed partly to unwinding stretched positions and concerns about the sustainability of AI-related earnings and capital expenditure growth, and the re-escalation of the Middle East conflict, which lifted energy prices and sovereign yields.
The Committee also referenced ongoing Bank of England work already in train, including efforts on gilt repo market resilience and the private markets System-Wide Exploratory Scenario (PM SWES) exercise, which is designed to fill data gaps on private credit — a market the FPC said remains vulnerable to a tightening in financing conditions.
Risks the FPC Says Could Still Bite
Several judgements in the record are explicitly conditional. The FPC said the risk of a sharper equity correction persists, notably if there is a more significant shock to earnings expectations tied to concerns about the pace of AI development or adoption. The risk of a sharp adjustment in the gilt market also persists, given elevated hedge fund leverage and deeper interconnections between vulnerabilities.
It is not yet clear how the Middle East conflict or energy prices will evolve, and the record does not quantify the potential impact on UK growth or interest rates. The full picture of AI-related financing also remains unclear: the Committee noted that opacity and ‘circular arrangements’ complicate risk assessment, and the PM SWES exercise is still underway to fill data gaps in private credit markets.
Upcoming FPC Actions and Exercises
The FPC said it would continue to monitor the interconnected risks it identified, with the gilt repo market resilience workstream and the private markets System-Wide Exploratory Scenario exercise both ongoing. The Committee urged firms to engage with guidance from regulators, the National Cyber Security Centre, and sector groups including the Cross Market Operational Resilience Group, the Frontier AI Information Sharing Forum and the AI Consortium, to prepare for AI-related cyber and operational risks.
The FPC’s next scheduled meeting and record will provide an updated judgement on whether the risks flagged in September have crystallised, eased, or intensified — particularly the path of sovereign yields, AI-related debt issuance and developments in frontier AI.
Key Questions
What is the Financial Policy Committee?
The FPC is a Bank of England committee that meets to identify risks to UK financial stability and agree policy actions aimed at safeguarding the resilience of the UK financial system.
Why does the FPC think financial stability risks have risen?
According to the September 2026 record, the re-escalation of the Middle East conflict, rising energy prices, sovereign bond yields at their highest levels since 2008, elevated hedge fund leverage in the gilt market, and rapid AI-related debt issuance have all raised the likelihood of interconnected vulnerabilities crystallising at the same time.
Is the UK banking system at risk?
The FPC judged that the UK banking system remains appropriately capitalised with high levels of liquidity, and that past stress tests demonstrated resilience to a scenario with higher energy prices. Households and corporates were also judged resilient.
What did the FPC say about AI risks?
The Committee highlighted rapid AI-related debt issuance, opaque and sometimes ‘circular’ financing arrangements, the sharp July fall in AI equity valuations, and frontier AI test-environment incidents where autonomous models took unexpected actions. It urged firms to prepare for AI-related cyber and operational risks.
Were there losses from the July AI valuation fall?
Yes. The FPC said some leveraged investors with concentrated positions suffered significant losses, but there was no spillover to core markets, and equity markets in aggregate remained resilient to rising bond yields.
