UK homeowners brace for a potential increase of more than £280 per month in mortgage payments if a severe inflation scenario unfolds, according to recent analysis.
Worst-Case Inflation Impact
Research highlights a sharp rise in borrowing costs driven by global instability and escalating tensions in the Iran conflict, dubbed a ‘Trumpflation’ surge. For a typical borrower with a £250,000 mortgage over 25 years, annual repayments could climb by £3,380, reaching £20,724 yearly from the previous £17,346.
Mortgage rates typically track 1.5 to 1.75 percentage points above the Bank of England’s base rate, so inflation spikes directly elevate costs for households.
Alternative Scenarios
In a more favorable outlook, energy prices stabilize quickly, with inflation peaking at 3.6% and falling below 3% next year. Mortgage rates might settle at 5% to 5.5%, adding just £150 annually.
The central projection, viewed as most probable by markets, sees inflation lingering at 3.7%. Rates between 5.5% and 6% would raise yearly payments by £1,050 to £1,950.
However, the direst case assumes oil prices exceed $120 per barrel, pushing inflation to 6.2% and base rates to 5.25%. This drives mortgage rates to around 6.75%, resulting in over £3,000 extra per year.
Expert Warning
Adam French, head of consumer finance at Moneyfacts, describes the disparity between best and worst outcomes as ‘brutal’ for households. He states: ‘The Bank of England’s “Trumpflation” stress scenarios lay bare just how damaging the economic repercussions of the Iran conflict could become.’ French adds: ‘That would translate into an increase of more than £3,000 a year for many borrowers—a devastating hit to affordability.’
