FPC’s April Warning: Private Markets Under Stress, AI Risks Escalate

The Bank of England's Financial Policy Committee published its record for the 27 March 2026 meeting in April, and while the headline is that the UK banking system remains resilient, the detail tells a more nuanced story. Three themes dominate: private markets stress, mortgage book re-pricing, and the rising systemic risk of advanced AI in financial services.
Private Markets: Opacity Meets Volatility
Before the Iran conflict, the FPC had already identified worsening vulnerabilities in private credit and risky credit markets. Some sharp moves in technology-focused equity valuations had rattled investors. The conflict's supply shock has now intensified those pressures: higher rates increase debt servicing costs for leveraged borrowers, lower growth erodes asset quality, and energy-intensive industries face refinancing risk as their operating economics deteriorate. The FPC's language here is notably blunt, concerns about opacity, valuation methodologies, and structural liquidity mismatch are flagged as central to recent redemption episodes in private markets.
The FPC flagged that UK private markets are 'heavily dependent on overseas investors', which means a flight to safety triggered by global instability carries direct transmission risks to domestic credit conditions.
Mortgage Market: Repricing in Real Time
The FPC noted 'some withdrawal and repricing of mortgage products' in response to swap rate movements. That is an understated description of what happened: fixed rates jumped sharply in a week, first-time buyer demand fell, and house prices softened, particularly at the prime end where London transaction volumes fell over 30% year-on-year in some segments. The FPC emphasised that the banking system remains well-capitalised and is not restricting lending, but the operational stress on mortgage operations teams, managing product withdrawals, repricing pipelines, and customer communications has been significant.
AI: A Systemic Concern Moving Up the Agenda
Perhaps the most forward-looking part of the FPC record is its treatment of advanced AI. The Committee asked the Bank and the FCA to undertake specific work on agentic AI. This refers to AI systems that act autonomously in payments and financial markets. The request followed the Committee’s conclusion that, although AI has not yet been adopted in ways that present systemic risk today, the trajectory is changing quickly. The concentration risk in AI service providers (the top three cloud providers account for 73% of AI infrastructure across financial firms) is already a supervisory concern. The FPC's 2026 joint AI survey with the FCA will be a key data gathering exercise and its results should be watched closely by any firm deploying AI in trading, credit decisions, or customer operations.
