BoE warns AI leverage and crowded debt trades risk crystallising
The Bank of England’s Financial Policy Committee has warned that a cluster of vulnerabilities—spanning highly leveraged AI equities, stressed private credit, and crowded sovereign debt trades—has become more likely to crystallise simultaneously following Middle East turmoil.
The Bank of England’s Financial Policy Committee has warned that the probability of multiple financial vulnerabilities crystallising at the same time has increased since December. Geopolitical tensions in the Middle East triggered sharp rises in energy prices and sovereign bond yields, exposing underlying fragilities across global markets. Additionally, rapid advances in frontier artificial intelligence capabilities have introduced new cyber and operational resilience risks to the financial system.
A substantial increase in leverage within equity markets is a primary concern for regulators. The FPC noted that rising equity prices, particularly for a narrow set of AI-related companies, have been supported by significant hedge fund borrowing and rapid growth in leveraged exchange traded funds. This creates interconnected risks through prime brokers and sovereign debt markets.
The unprecedented pace of AI investment is also spilling over into credit markets at an accelerating rate. AI-related companies are drawing heavily on public markets, private credit, and structured finance, often employing complex and opaque debt structures. A reassessment of long-term earnings prospects could trigger a sharp equity sell-off, amplifying risks tied to this corporate debt.
Separate stresses are building in riskier credit markets, where investor sentiment had already weakened prior to the Middle East conflict. Several retail funds have faced elevated redemption requests and implemented limits, underlining liquidity mismatches and valuation concerns. Furthermore, sovereign bond markets face historically high issuance with shorter maturities, dominated by a small number of highly leveraged hedge funds using similar strategies.
The recent period of gilt market volatility demonstrated how these dynamics interact under pressure. Moves in UK sovereign yields were amplified by hedge fund deleveraging during the peak of the conflict. The FPC emphasised that market participants must better understand the concentration and interconnections of their exposures to manage the risk of a disorderly unwind.
Systemic resilience
Despite these threats, the UK’s core financial infrastructure has held up. A US-Iran memorandum of understanding has since pulled energy prices back to just above pre-conflict levels, reducing immediate dangers. The Bank's second system-wide exploratory scenario is currently examining how stress propagates in these vulnerable credit markets.
The FPC confirmed that UK banks remain appropriately capitalised with high liquidity, while household and corporate aggregate indebtedness stays low relative to historical averages. Past stress tests demonstrate the banking system can absorb severe energy price shocks while continuing to lend to the real economy.
