In the wake of the Iran war, Britons looking for new mortgages are facing markedly higher costs, with average payments climbing by nearly £800 more per year than they were before the conflict. This surge has been attributed to a phenomenon referred to as 'Trumpflation', which has led to a swift increase in mortgage rates across the UK. According to Moneyfacts, nearly 700 mortgage deals have been withdrawn by lenders as the economic implications of the war unfold, signaling a substantial shift in the housing market reminiscent of the volatility observed after the implosion of Liz Truss’s mini-budget in 2022.

Adam French, the head of consumer finance at Moneyfacts, points out that the war in the Middle East has significantly impacted UK mortgage rates, skyrocketing the average two-year fixed rate from 4.83% to 5.28%. This change represents the highest rate level since April 2025. Similarly, five-year fixed rates have increased from 4.95% to 5.32%, marking a record high since February 2025. Such dramatic shifts in mortgage rates may deter borrowers from securing fixed-rate deals, particularly challenging for those who are already struggling with financial pressures.

For homeowners or potential buyers, this increase translates to substantial financial burdens, with calculations showing that a borrower with a £250,000 mortgage over 25 years could see annual costs rise by £788 for a two-year fix, or £651 for a five-year deal. This escalation comes at a time of growing concern about financial stability amidst geopolitical events, emphasizing the interconnectedness of global issues and local economic realities. As the UK housing market adjusts, consumers will need to navigate these rising costs while the fallout from international conflicts continues to unfold.
