How the Middle East Conflict Is Pushing UK Mortgage Rates Higher — and What to Do About It

The global economic shock triggered by the ongoing Middle East conflict is having a direct and measurable impact on UK mortgage rates. Borrowers need to understand what is happening and why before deciding whether to fix, wait, or act.

UK Particularly Exposed

Both the IMF and OECD have cut the UK's 2026 growth forecast by 0.5 percentage points — the largest downgrade of any major economy. UK government bond yields rose by more than any other G7 country except Italy in March 2026, driven by rising inflation expectations and stretched public finances. The knock-on effect pushed mortgage rates up by approximately one percentage point. That is not a small number — a one percentage point increase on a £200,000 mortgage over 25 years adds roughly £100 to £130 to your monthly repayment.

Inflation Is Rising Again

The Consumer Prices Index rose to 3.3% in the 12 months to March 2026, up from 3.0% in February. This upward move in inflation reduces the Bank of England's room to cut the base rate — the tool it would normally use to ease pressure on borrowers. The Bank of England has warned that around 1.3 million more households could face higher mortgage payments by 2028 as a direct result of the conflict, bringing the total number of affected households to 5.2 million.

The Swap Rate Problem

Mortgage rates do not just follow the Bank of England base rate. They follow swap rates, which respond instantly to market sentiment. When global uncertainty rises, swap rates rise — and fixed rate mortgage pricing follows, even if the base rate itself has not moved. That is exactly what has happened in recent months. Several lenders have increased fixed rates despite the base rate remaining unchanged, because the underlying cost of funds has risen.

What Should Borrowers Do?

Those coming off fixed deals in the next three to six months should not wait for rates to fall. The trajectory in the near term is uncertain, and the risk of rates moving higher before they fall is real. Locking in a competitive fixed rate now provides certainty and protection in a volatile environment. If you are already on your lender's Standard Variable Rate, the case for switching is even more compelling — the average SVR of 7.15% is dramatically higher than the best five-year fix available today.
