Why are UK mortgage rates rising now?

Mortgage rates are rising because UK swap rates jumped after renewed Middle East tensions lifted inflation and risk premiums. Higher swaps increase lenders’ hedging costs, which then feed into fixed mortgage pricing. The shift happened quickly, so banks and building societies moved to reprice deals to protect margins in a volatile market.

How do swap rates influence fixed mortgages?

Swap rates reflect future policy rate and inflation expectations. Lenders use swaps to hedge fixed loans. When swaps rise, hedging becomes more expensive, so lenders lift fixed mortgage rates or tighten products. When swaps fall and stay low, lenders can cut pricing, though competition and funding mix also play a role.

What should I do if my fixed deal ends soon?

Start early. Secure a new offer up to six months ahead, then keep checking in case rates drop before completion. Compare total cost, including fees and incentives. Consider flexibility, such as trackers without exit fees, but stress test payments. If budgets are tight, a longer fix may offer better protection.

Will the Bank of England cut rates on 19 March?

A cut is possible later in 2026, but the 19 March meeting may prioritise data dependence given sticky services inflation and recent swap moves. Officials will need clearer signs of cooling wages and prices. Markets now see a slower start to easing, so any shift will hinge on near‑term inflation and labour data.
