Barclays has become the first major bank to reintroduce a mortgage deal with an interest rate below 4 per cent, following the surge in swap rates triggered by the Iran war. The new product offers a rate of 3.96 per cent for a two-year fixed period, but it is exclusively available to the bank's Premier customers.
In the wake of the conflict, numerous lenders withdrew hundreds of mortgage products from the market, with all sub-4 per cent deals swiftly disappearing. This left homeowners and prospective buyers who had not yet secured a rate facing significantly higher repayment expectations.
After a period of volatility, swap rates—which underpin mortgage pricing—have stabilised, prompting some lenders to lower rates again. Barclays has followed suit by cutting rates on new purchase and remortgage products. Among the offerings is a two-year tracker mortgage for new home purchases with a 75 per cent loan-to-value ratio, featuring a 3.96 per cent interest rate and a £999 product fee.
To qualify for Premier status, applicants must hold a current account and either earn £75,000 annually or have at least £100,000 in savings, investments, or a combination of both held with Barclays.
For remortgage deals, the best rate among the newly adjusted products is 4.8 per cent on a five-year fix, also carrying a £999 product fee.
Experts advise homeowners nearing their renewal date to seek tailored guidance, with 1.8 million people expected to require a new deal during 2026. Borrowers can typically secure a new deal up to six months before their current one expires, and the headline interest rate is not always the most critical factor. Product fees vary by lender, and the mortgage term length is equally important.
Paul Heywood, chief data officer at Equifax UK, noted that British households are now paying 50 per cent more on monthly repayments compared to four years ago, with further interest rate increases possible in 2026. "Average monthly repayments for new mortgage lending remain 50 per cent higher than in January 2022, and this is now compounded by central bank policymakers under pressure to address inflation and the impact of the ongoing conflict in the Middle East. This could spell disappointment for any borrowers hoping for a base rate cut," he said.
The near-term trajectory of interest rates remains uncertain, and mortgage deals will reflect this volatility. Even as Barclays reintroduces the first sub-4 per cent deal, it has also raised rates on some other products.
