Sub-4% Mortgage Availability Crashes Amid 'Trumpflation' Fears
The availability of fixed-rate mortgage deals below 4% has experienced a dramatic collapse, with financial experts attributing the sharp decline to "Trumpflation" pressures stemming from the US war with Iran. This geopolitical conflict is now directly impacting UK consumers, as lenders rapidly withdraw products and increase rates in response to volatile financial markets.
Mortgage Market Sees Dramatic Product Withdrawal
According to financial information website Moneyfactscompare.co.uk, the number of available fixed-rate mortgage deals below 4% has plummeted from 490 on March 9 to just nine by Tuesday morning. This represents one of the most significant contractions in mortgage product availability in recent memory.
Across the broader mortgage market, the situation remains concerning with 689 fewer products available compared to just days earlier. Banks and building societies are responding to rising swap rates – the rates lenders use to price mortgages – by both increasing interest rates and completely withdrawing products from the market.
Borrowers Face Substantial Cost Increases
Financial experts warn that new borrowers could now pay hundreds of pounds more annually compared to just weeks ago. Adam French, head of consumer finance at Moneyfacts, provided specific figures illustrating the dramatic shift.
The average two-year fixed rate has surged from 4.83% at the beginning of March to 5.28% today – representing its highest level since April 2025. Similarly, the average five-year fix has increased from 4.95% to 5.32%, reaching its highest point since February 2025.
For a borrower with a £250,000 mortgage over 25 years, these rate increases translate to paying £788 more per year on a two-year fixed deal, or £651 more annually on a five-year arrangement compared to just a fortnight earlier.
Expert Analysis and Market Outlook
Rachel Springall, a finance expert at Moneyfactscompare.co.uk, explained the market dynamics: "Borrowers looking for the lowest fixed rates will be disappointed to see the demise of sub-4% mortgages, but they are not sustainable with swap rates increasing. Lenders examine margins very carefully, so it would be unwise to price their deals too low if expectations point toward rising interest rates, even over the short-term."
Springall further suggested that if inflation experiences a significant jump, there could potentially be an increase to the Bank of England's base rate "before the year is over." She advised concerned borrowers to seek professional financial advice when searching for new deals.
Bank of England Decision Looms
The Bank of England is scheduled to make its next base rate announcement on Thursday, though expectations for any potential rate cut have diminished substantially in recent days. Market volatility triggered by the Middle East conflict has altered the economic landscape significantly.
French concluded with a sobering warning: "Choice continues to fall as lenders pull deals and reprice in response to rapidly rising funding costs. Borrowers may need to brace for further volatility in the weeks ahead as the global economy prepares for a 'Trumpflation' wave."
The term "Trumpflation" refers to inflationary pressures resulting from policies and geopolitical actions associated with the US administration, which are now reverberating through international financial markets and directly affecting UK mortgage borrowers.
