UK Mortgage Approvals Sink to 32-Month Low as Iran War Fallout Squeezes Borrowers

Britain’s housing market is buckling under the weight of a distant war. Mortgage approvals fell to their lowest level in nearly three years in August, as the fallout from the conflict in Iran continues to ripple through household finances, pushing up borrowing costs and denting confidence among would-be buyers.

According to Bank of England figures released Tuesday, just 54,918 mortgages for new home purchases were approved in August — the weakest monthly total since December 2023 and a fresh signal that the housing market’s recovery has stalled. The seasonally adjusted data underscores how a geopolitical crisis thousands of miles away has translated into very real financial strain for people trying to buy a home in the UK.

The chain of cause and effect is straightforward, if unwelcome: since fighting broke out in Iran in late February, oil prices have surged, reigniting inflation fears and dashing hopes that the Bank of England would continue cutting interest rates. Lenders have responded by raising mortgage rates sharply, making home loans markedly more expensive at precisely the moment many households were hoping for relief.

Simon Gammon, managing partner at Knight Frank Finance, said the slowdown built steadily over the summer. “Buying activity weakened through the summer as rising energy prices pushed up borrowing costs,” he said, noting that lending to homebuyers fell 15% in August compared with the same month last year — a striking year-on-year decline that points to a market losing momentum rather than simply cooling seasonally.

Remortgaging activity, too, is losing steam. Approvals for switching or renewing existing home loans dipped to roughly 34,000 in August, down slightly from 34,600 in July. That is a curious wrinkle: normally, a wave of borrowers coming off cheaper fixed-rate deals would be expected to shop around and refinance in large numbers. Instead, many appear to be holding back, perhaps hoping rates will ease before they commit, or resigned to accepting whatever their current lender offers rather than facing the market head-on.

The numbers behind the squeeze are stark. The Bank of England found that the “effective” interest rate on newly drawn mortgages rose to 4.60% in August, up from 4.45% in July — a jump in just one month that would have been unthinkable a year ago when rate cuts still seemed plausible. Separately, Moneyfacts, the financial data firm, reported that the average five-year fixed mortgage rate climbed to 5.94%, its highest level since October 2023. Two-year fixed deals are similarly expensive, averaging 5.93%, the priciest since July 2024.

For everyday borrowers, those percentage-point shifts translate into hundreds of pounds a month in additional repayments — often the difference between a purchase going ahead and a buyer walking away from a deal altogether.

Katie Clinton, head of financial services advisory at KPMG UK, said the figures show affordability pressures are now the dominant force shaping the housing market. “A further fall in mortgage approvals in August points to affordability pressures continuing to weigh on housing demand, as the shocks from the Iran conflict push up both inflation and mortgage rates,” she said. She added that the drop in remortgaging suggests “refinancing demand softened, despite many borrowers reaching the end of existing fixed term rates” — a sign that households may be delaying decisions in the hope conditions improve, even as their existing cheap deals expire.

The government has tried to counter the gloom with its newly announced “Your First Home” scheme, aimed at helping first-time buyers onto the property ladder. But economists are sceptical that a targeted support scheme can offset the broader drag from higher borrowing costs. Paul Dales, chief UK economist at Capital Economics, warned that the prospect of mortgage rates staying above 4.5% for most of 2027 would weigh far more heavily on the market than any government initiative. “Mortgage rates staying above 4.5% for most of 2027 would have a larger influence on activity than the government’s new scheme,” he said, in effect arguing that macroeconomic headwinds will overpower policy tailwinds.

The broader picture is one of a housing market caught between geopolitics and monetary policy, with ordinary buyers absorbing the consequences of decisions made in oil markets and central bank meeting rooms far removed from their own kitchen tables. Estate agents across England and Wales have already reported a discernible cooling in activity tied to the war, and earlier this year the Bank of England itself warned that the conflict could push up mortgage payments for an additional 1.3 million households as fixed-rate deals expire and borrowers are forced onto costlier new terms.

With inflation expectations still elevated and interest rate cuts looking increasingly unlikely in the near term, few analysts expect a quick turnaround. For now, the message from the data is unambiguous: as long as the war in Iran continues to unsettle energy markets, Britain’s mortgage market — and the millions of households who depend on it — will keep feeling the strain.
