Impact of the Iran War on the UK Mortgage Market

The ongoing war in Iran, which began on February 28, 2026, is significantly affecting the UK mortgage market. In response to escalating oil prices and inflation concerns, lenders have withdrawn over 1,500 mortgage products from the market within a short span, leading to a sharp increase in mortgage rates. For instance, two-year fixed mortgage rates have surged from approximately 4.8% to around 5.5%. This shift translates to an additional £90 in monthly payments for borrowers with a £200,000 mortgage over 25 years, resulting in nearly £1,000 more in annual costs.

The conflict in the Middle East is disrupting oil production, impacting a region that supplies about one-third of the world's oil and 20% of its liquid natural gas. This disruption has led to higher energy prices, which in turn affect various sectors, including transport, food, and manufacturing. The rising costs of energy and fertiliser—due to supply bottlenecks—are contributing to an anticipated inflation rate of around 4% in the UK, up from a previous estimate of 2.5%. Such inflationary pressures complicate the Bank of England's efforts to maintain stable interest rates.

UK government bonds, or gilts, are also experiencing increased yields as investors adjust their expectations regarding inflation and interest rates. Higher gilt yields raise the funding costs for commercial banks, which are subsequently passed on to consumers through elevated mortgage rates. Prior to the conflict, financial markets had anticipated a gradual decline in interest rates throughout 2026; however, current expectations now include a potential increase in the Bank of England's base rate by the end of the year.

The UK's economic vulnerability is exacerbated by its reliance on energy imports, with approximately 44% of its energy sourced externally. This dependency makes the UK particularly susceptible to global price fluctuations. As a result, the combination of rising mortgage costs, stagnant income growth, and reduced job opportunities is likely to create a prolonged squeeze on disposable income for many households. Even if the conflict were to cease immediately, the economic ramifications are expected to linger.

Critics argue that the government's economic policies have not adequately prepared the UK for such external shocks. They contend that the reliance on imported energy and the slow growth of the domestic economy have left households vulnerable to global market fluctuations. This situation raises concerns about the long-term sustainability of the UK’s economic health in the face of ongoing international conflicts.
