Bank of England Warns Iran Conflict Could Trigger UK Financial Crisis

The Bank of England has issued a stark warning that Britain faces a heightened risk of financial crisis in the wake of the Iran conflict, cautioning that the instability could leave households contending with elevated borrowing costs and surging prices for an extended period.

The Bank’s Financial Policy Committee (FPC), which holds responsibility for monitoring systemic financial stability, confirmed that the conflict has already contributed to a significant expansion in the number of mortgage borrowers facing increased repayments. Approximately 5.2 million borrowers, representing more than half of all mortgaged homeowners, are now projected to face higher payments by 2028; a figure that stands markedly above the 3.9 million estimated prior to the outbreak of hostilities.

The escalation in mortgage costs follows a period of acute market disruption, during which hedge funds were compelled to unwind approximately £19bn in bets positioned on interest rate reductions. As the prospect of lower borrowing costs receded, the resulting volatility in short-term rates drove lenders to withdraw more than 1,500 mortgage deals from the market, placing immediate pressure on prospective borrowers and those seeking to remortgage.

Bank of England Governor Andrew Bailey sought to temper some of the more aggressive market expectations, stating that investors were “getting ahead of themselves” in pricing interest rate rises. Markets are currently anticipating two rate increases before the year’s close, having previously expected as many as four; a recalibration that nonetheless reflects the degree to which the conflict has reshaped the interest rate outlook.

The FPC’s assessment of the broader macroeconomic picture is sobering. The closure of the Strait of Hormuz, through which approximately one fifth of global oil and gas exports ordinarily transit, has driven energy prices sharply higher and prompted serious warnings regarding the prospect of a global recession. Rising petrol and diesel costs are already squeezing household finances, yet Chancellor Rachel Reeves signalled that targeted support for struggling families is unlikely to materialise before September.

Policymakers characterised the conflict as having rendered the global economy “materially more unpredictable,” at a juncture when equity valuations were already stretched and vulnerabilities in private credit markets and highly indebted sovereign states were already cause for concern. The FPC warned explicitly of “large, frequent and potentially overlapping shocks and periods of intense volatility,” underscoring the systemic nature of the risks now in play.

Governor Bailey drew particular attention to the private credit market, a USD 18tn (GBP 13.5tn) sector in which private equity funds extend lending to businesses outside the traditional banking system. Bailey described current conditions in this space as reminiscent of the prelude to the 2008 financial crisis, referencing the recent collapse of UK lender Market Financial Solutions (MFS) as an unsettling signal. Drawing a parallel to the subprime mortgage crisis, he cautioned against dismissing isolated lender failures as idiosyncratic events, noting that such reasoning proved deeply flawed in the lead-up to the last global financial meltdown. Several funds in the private credit space have already moved to restrict investor withdrawals, a development that carries its own connotations of systemic fragility.

The FPC also flagged the growing correlation between equity and gilt markets, driven in large part by hedge fund activity across both asset classes. A sharp correction in equity markets, the committee cautioned, could transmit stress directly into the gilt market, amplifying instability across the broader financial system.

At the sovereign level, the outlook is equally concerning. The UK is forecast to spend in excess of £100bn on debt interest servicing alone in the current fiscal year, a burden that materially constrains the government’s capacity to deploy fiscal stimulus in response to future economic shocks. The FPC stated that the conflict has worsened the global sovereign debt outlook, with the potential to suppress growth, sustain elevated interest rates, and intensify spending pressures simultaneously. Should multiple vulnerabilities crystallise concurrently, the committee warned, the amplified effect on financial stability, and on the provision of core financial services to UK households and businesses, could be severe.

While the FPC noted that household debt remains relatively contained by historical standards and that immediate risks appear broadly manageable, the tone of the committee’s latest communiqué leaves little doubt that policymakers are acutely alert to the possibility of a more disruptive scenario materialising. The convergence of geopolitical disruption, tightening financial conditions, and pre-existing structural vulnerabilities across credit markets and sovereign balance sheets presents a risk configuration that warrants close and continuous monitoring by investors.
