Barclays has become the biggest UK lender so far to cut mortgage rates as the continued uncertainty caused by US tariff policy raises expectations of interest rate cuts this year.
Barclays is reducing the rate on certain fixed-term deals to 3.99%, joining several other lenders who have cut mortgage rates this week.
US President Donald Trump has brought in import taxes on dozens of countries since re-entering the White House, although on Wednesday he paused the higher rate on some of them.
But concerns that tariffs may cause an economic slowdown has led to many analysts predicting the Bank of England will reduce borrowing costs by more than expected this year in order to boost growth.
Barclays is cutting rates on several of its products, including its two-year and five-year fixed deals, from Friday.
However, these fixed rates of below 4% are only available to borrowers with a 60% loan-to-value and an £899 fee applies.
Coventry Building Society, TSB, the Co-operative Bank and Bank of Ireland are among those to have cut rates this week.
According to the financial data company Moneyfacts, the average two-year fixed mortgage rate ticked down on Thursday from 5.3% to 5.29%. The average five-year fix dipped from 5.15% to 5.14%.
