The recent turbulence in the UK bond market is stoking concerns about higher borrowing costs for households, with fixed-rate mortgages the most immediately exposed. Because such mortgages are priced off wholesale "swap rates" rather than the Bank of England's base rate, the sharp rise in government borrowing costs has already prompted Coventry Building Society to announce increases for new and existing borrowers, with other lenders expected to follow suit. This matters most for anyone remortgaging soon or buying their first home, though experts note the reaction so far is milder than after the 2022 mini-budget crisis.

On Thursday, average rates stood at 5.59% for two-year fixes and 5.63% for five-year fixes, up from 5.9% and 5.78% respectively in April, and advisers are urging borrowers to lock in offers now. Pension savers are less uniformly affected: those under 50 are typically invested in equities rather than bonds and could even benefit from a lower FTSE, while retirees drawing fixed gilt income are largely insulated. The greatest risk falls on those nearing retirement under "lifestyling" strategies that shift pensions into bonds, who may want to review their holdings, whereas savings account holders could see some upside from the wider market shifts.
