Overview
- Moneyfacts estimates a worst-case increase of roughly £280 to £300 a month, or about £3,380 a year, for a £250,000 mortgage over 25 years if the Bank rate reaches 5.25%.
- The Bank of England’s stress test links a US–Iran conflict to oil above $120 a barrel and UK inflation near 6.2%, which would force multiple rate rises to curb prices.
- Mortgage pricing usually sits 1.5 to 1.75 percentage points above the Bank rate, so a 5.25% base rate would push typical mortgage rates above about 6.5%.
- Markets have already shifted toward higher rates and lenders have pulled cheaper deals, with average two-year fixes up from 4.83% to 5.77% and five-year fixes from 4.95% to 5.68%.
- The BoE says average monthly payments are expected to rise by about £80 over the next three years, and Moneyfacts advises borrowers to consider locking in a new deal up to six months early.
