Surge in UK Mortgage Costs Amid Iran Conflict

Recent data indicates that the average cost of a new mortgage in the UK has surged by £788 annually within just two weeks, primarily due to the geopolitical tensions arising from the US-Israel strikes on Iran that began at the end of February. This increase affects homeowners and buyers securing a 25-year mortgage of £250,000, with the average two-year fixed mortgage rate climbing from 4.83% to 5.28%, marking its highest level since April 2025. Similarly, the average five-year fixed rate has risen from 4.95% to 5.32%, the highest since February 2025. The rapid escalation in rates has led to nearly 700 mortgage products being withdrawn from the market, representing almost 10% of available options.

The sudden rise in mortgage costs poses significant challenges, particularly for first-time buyers and those whose fixed-rate deals are nearing expiration. Adam French, head of consumer finance at Moneyfacts, noted that the current situation is reminiscent of the upheaval following the 2022 mini-budget, where a substantial number of mortgage deals were also retracted. The withdrawal of competitive sub-4% mortgage deals by major lenders such as Barclays, HSBC, NatWest, Nationwide, and Santander has further exacerbated the situation, leaving borrowers with limited options.

Critics argue that the rapid increase in mortgage rates could lead to a slowdown in housing market activity, as potential buyers may be deterred by the heightened costs. The uncertainty surrounding future interest rates, particularly in light of the upcoming Bank of England Monetary Policy Committee meeting, adds to the anxiety among borrowers. Paula Higgins, CEO of HomeOwners Alliance, noted that many households are already feeling uncertain about the direction of mortgage rates, which could lead to inaction among homeowners.
