UK Mortgage Market Enters Turbulent Phase as Geopolitical Crisis Bites
The first quarter of 2026 has delivered a stark lesson in volatility for UK mortgage borrowers, with a rapid shift from competitive lending to market uncertainty. This dramatic change has been driven by escalating geopolitical tensions and their economic repercussions.
Market Conditions Deteriorate Rapidly
Where lenders were recently competing with sub-4% deals, March has witnessed hundreds of residential mortgage products withdrawn from the market. This reversal stems from two primary factors: the ongoing conflict involving Iran impacting the UK economy, and rising swap rates as speculation grows about potential interest rate hikes.
Ryan Brailsford, director of sales at Pepper Money, explains: "Rising energy prices and geopolitical tensions have pushed up swap rates, which lenders use to price fixed-rate mortgages. Several high street lenders have already responded by increasing their rates."
According to Moneyfacts data, average mortgage rates climbed above 5% in March, reaching their highest level in seven months and approaching 5.5% as April approaches.
Forecasting Becomes Increasingly Difficult
Craig Fish, founder of broker Lodestone Mortgages, describes the current environment as "the most unpredictable forecasting environment in recent years." This uncertainty makes forward planning exceptionally challenging for both existing homeowners and prospective first-time buyers.
The timing is particularly significant as the Financial Conduct Authority estimates approximately one million fixed-rate mortgage deals are due to expire between April 1 and the end of September 2026. This expiration wave will likely trigger substantial demand for new mortgage agreements.
Bank of England's Dilemma
The Bank of England's base rate currently stands at 3.75%. Prior to the latest Middle East developments, forecasters had anticipated a rate cut as early as March. However, rising oil prices and the threat of renewed inflation have shifted expectations toward maintaining current rates.
Jonathan Samuels, chief executive of Octane Capital, emphasizes: "Mortgage rates can shift far more quickly than many borrowers realize because they are influenced not just by the Bank of England base rate, but by wider economic sentiment and global events."
Fish adds further context: "If energy prices remain elevated through the coming months, inflation will prove stickier than the Bank of England had hoped, reducing both the room and appetite for further base rate cuts." However, he notes that if the conflict stabilizes, "the underlying UK picture of weak growth and rising unemployment still gives the Monetary Policy Committee good reason to cut, and reductions by September remain plausible."
Expert Predictions for 2026
As of early March, Moneyfacts data shows the average two-year fixed rate mortgage across all loan-to-value ratios was 4.82%, with the average five-year fix at 4.94%. Looking ahead to the third quarter of 2026, industry experts provided cautious forecasts.
Based on mean figures from representatives at Jackson-Stops, JLL, Lodestone Mortgages, Pepper Money, and SPF Private Clients, the average two-year fixed rate could reach approximately 4.7% by September, with the five-year rate potentially at the same level.
Nick Leeming, chairman of Jackson-Stops, cautions: "Whilst we had anticipated small rate reductions throughout 2026, the international conflict and geopolitical environment have changed radically. As such, any predictions are very difficult."
Despite the current volatility, some experts see relative stability in the longer term. Marcus Dixon, director of UK residential research at JLL, observes that current rates "remain more competitive than borrowers could secure this time last year, which will, we expect, bring more buyers to the market in 2026."
Sharief Ibrahim, head of residential at CBRE, adds: "The Bank of England may find it harder to start easing rates because of the risks around inflation. That said, our latest residential forecasts suggest a relatively steady outlook for mortgages over the next 18 months."
Practical Advice for Borrowers
In this uncertain environment, experts recommend specific strategies for mortgage seekers. Paula Higgins, chief executive of HomeOwners Alliance, advises working with a mortgage broker who "can help you find the right deal for you, secure a rate in advance, and keep it under review in case a better option appears before you complete."
Mark Harris, chief executive of SPF Private Clients, suggests proactive measures: "We could see lenders increase mortgage rates to reflect higher swap rates if they continue to rise. Borrowers planning to take out a fixed-rate mortgage in the next few weeks or months may wish to secure a product now."
Harris explains the rationale: "This will give you peace of mind, and if rates fall by the time you come to take out the mortgage, you should be able to switch onto a cheaper deal at that time. However, if rates have risen, you will be glad you took action when you did."
The UK mortgage market faces continued uncertainty through 2026, with geopolitical developments and economic indicators creating a complex landscape for both lenders and borrowers seeking stability in turbulent times.
