Just months after UK borrowers began to feel the benefit of falling mortgage costs, rates have snapped back above 5%, erasing recent gains and plunging the home loan market into fresh uncertainty. The catalyst is the expanding military conflict in the Middle East, which has unsettled global energy markets, raised inflation expectations, and prompted lenders to rapidly revise their product pricing. In fewer than 48 hours, the shift has undone months of cautious progress and raised serious questions about the near-term outlook for UK borrowing costs.
Leading banks and building societies have wasted little time in responding to rising swap rates, which serve as the primary pricing mechanism for fixed-rate home loans. HSBC, Barclays, Halifax, and Nationwide have all raised rates, with HSBC implementing a second round of increases effective Thursday. The scale of withdrawal activity — close to 500 residential products pulled from the market — has drawn comparisons to the financial turbulence of late 2022, though analysts note the current episode remains less extreme than the mini-budget shock that wiped out 935 deals in a single day.
The numbers tell a clear story. The average two-year fixed mortgage rate stands at 5.01% as of Wednesday, compared with 4.84% immediately before the outbreak of conflict. The five-year fixed rate has reached 5.09%. Adam French of Moneyfacts characterised the past 48 hours as among the most turbulent the UK mortgage market has experienced since the aftermath of the September 2022 mini-budget, noting that the pace of change had been remarkably swift.
At the heart of the issue is the relationship between Middle East conflict, oil prices, and inflation. Higher energy costs resulting from the war are expected to push consumer prices higher, complicating the Bank of England’s ability to continue cutting rates. The 1.8 million British households due to remortgage in 2026 had been counting on a friendlier rate environment — one that now looks considerably less likely to materialise.
Market pricing for the Bank of England’s March 19 meeting has shifted dramatically, with a rate cut now seen as almost impossible compared to an 80% probability before the conflict. The chances of a cut at any point in 2026 have fallen to 20%, from 50% only days ago. As French noted, how far and how fast mortgage rates continue to move will ultimately depend on how the geopolitical situation evolves and whether inflation pressures continue to build.
