Homeowners face another rise in mortgage costs this week as three major high street lenders increased their rates.
Nationwide and Halifax Adjust Rates
Nationwide has raised several fixed and tracker mortgage rates by up to 0.3 percentage points. Its lowest two‑year fix has moved from 4.2% to 4.5% with a £1,499 fee. The lowest five‑year fix now stands at 4.65%, up from 4.45%, also with a £1,499 fee attached.
For a £200,000 mortgage over 25 years, the increase means a change from around £1,106 a month to £1,129.
Halifax will also increase rates across all its fixed‑rate mortgage products from tomorrow. Earlier this week, HSBC raised rates too, including what had been the market’s lowest two‑year fix at 4.01%.
Impact on Borrowers and Remortgages
Rising mortgage rates continue to affect both new buyers and those remortgaging.
According to UK Finance, around 1.8 million households are due to remortgage this year, many coming off historically low fixed deals.
Since late February, the cheapest two‑year fixed rates have moved from roughly 3.5% to 4.15%, and the lowest five‑year fixes have seen a similar rise.
Mortgage Market Volatility and Lender Repricing
Experts note that lenders are adjusting rates frequently due to volatile market conditions. Some have even paused lending products to reprice.
Currently, lenders such as Barclays, TSB, and NatWest have two‑year fixes around 4.3%, while HSBC and NatWest are offering five‑year fixes near 4.5%.

Why Are Mortgage Rates Rising?
Fixed‑rate mortgage pricing is closely tied to SONIA swap rates, which reflect the cost of bank‑to‑bank lending and expectations of future interest rate movements.
When SONIA swaps increase, fixed mortgage rates usually follow. These rates have risen sharply since unrest in the Middle East led to fears of higher energy costs and inflation.
Traders who previously expected interest rate cuts are now anticipating possible rate hikes.
-
Two‑year swap rates have risen from 3.36% to 4.2% since late February.
-
Five‑year swaps have climbed from 3.41% to 4.15% in the same period.
Although markets briefly calmed following reports of diplomatic progress, uncertainty remains high.
Continuing Uncertainty
Some analysts believe mortgage rates could rise further until global markets stabilise. They suggest that while political developments may cause short‑term dips, sustained stability is needed before mortgage pricing steadies.
