Millions of UK homeowners face significant mortgage cost increases as rates have surged from below five per cent to above that threshold in just a matter of weeks.
The rapid rise comes amid growing geopolitical instability, with data revealing that a typical mortgage now costs £788 more annually than before the Iran conflict began.
Jinesh Vohra, CEO of Sprive, said: “Data showing that a typical mortgage is now £788 a year more expensive than before the Iran war began underlines just how sensitive the market is to global events.”
Lenders have responded swiftly to the volatile conditions by repricing deals and removing their most attractive products from the market.
The uncertainty has made timing the market virtually impossible for borrowers hoping to secure favourable terms.
Kevin Mountford, personal finance expert and co-founder of Raisin UK, warned that the consequences of Middle East hostilities are now hitting households rapidly.
“The knock-on implications of war in the Middle East are starting to come through thick and fast,” he said.
“In the last few days we’re seeing major jumps in mortgage rates. For anyone coming to the end of a fixed deal, the risk is not just a higher rate, but a sudden increase in monthly repayments at a time when wider living costs are still under pressure.”
Market turbulence combined with forecasts that inflation will climb to four per cent this year

GETTYMarket turbulence combined with forecasts that inflation will climb to four per cent this year, up from three per cent currently, has heightened concerns about financial security.
Mr Mountford stressed the importance of taking action promptly, noting that many borrowers can lock in new rates before their existing arrangements expire, offering protection against further market movements.
John Fraser-Tucker, Head of Mortgages at Mojo Mortgages, advised that the traditional approach of holding off for better deals has become increasingly risky.
“The ‘wait and see’ approach has become riskier,” he stated. “With swap rates (the price lenders pay for money) increasing already, the window for locking in a lower fixed rate may be narrowing.”

The broker has observed a 50 per cent surge in customers moving from initial enquiries to full applications, reflecting widespread urgency to beat further increases.
Approximately 1.8 million homeowners are scheduled to remortgage during 2026, and Mr Fraser-Tucker recommends those within three to six months of their deal ending should secure a rate now.
Most lenders permit borrowers to reserve a rate while retaining the option to switch if cheaper alternatives emerge later.
Mr Vohra emphasised that borrowers feeling the squeeze from elevated costs should concentrate on factors within their control rather than attempting to predict market movements.
First-time buyers may encounter slightly reduced competition for properties as market activity cools

GETTY“For those who can afford to, making small, regular overpayments remains one of the most effective ways to reduce the overall cost of a mortgage,” he said.
“Even modest contributions can help offset higher rates, shorten the mortgage term and save thousands in interest over time.”
First-time buyers may encounter slightly reduced competition for properties as market activity cools, though monthly payments will likely exceed expectations from earlier in the year.
Those on tracker mortgages, which follow the Bank of England base rate, face a different challenge: while an immediate rate hike appears unlikely, the anticipated path down to three per cent has almost certainly been pushed back.
