Fresh analysis reveals that customers seeking mortgages across the United Kingdom are confronting significant new challenges as major financial institutions have transformed the lending landscape since early March. According to data from Moneyfactscompare.co.uk released on Tuesday morning, a reduction to the Bank of England Base Rate (BBR) now appears increasingly improbable, with ongoing turmoil in mortgage repricing resulting in the complete disappearance of sub-4% fixed mortgage deals from the market.
Major Banks Withdraw Key Mortgage Products
Outlining the present circumstances, Moneyfactscompare stated that the selection of lenders providing sub-4% fixed rate deals had suffered what they described as a "significant blow." All major banking institutions, including Barclays, HSBC, Lloyds Bank, NatWest and Santander, have systematically raised their mortgage rates since the beginning of March.
The comprehensive analysis warned that sustained market uncertainty "can lead to further rate increases or product withdrawals." Specifically, Barclays, HSBC, NatWest, Nationwide and Santander no longer offer any sub-4% fixed deals, which were readily available to borrowers as recently as last week. Throughout the entire mortgage market, the last occasion when the lowest two-year and five-year fixed rates were priced above 4% occurred over a year ago, in February 2025, based on first-of-month data comparisons.
Average Rates Climb Above 5% Threshold
While year-on-year average mortgage rates across the two-year, five-year and ten-year fixed sectors have shown overall declines, recent increases have now driven the average two-year and five-year rates beyond the five per cent threshold. The Bank of England Base Rate was previously reduced to 3.75% in December 2025, providing some temporary relief to borrowers.
Since that reduction, the average standard variable rate (SVR) has dropped by 0.14%, moving from 7.27% to 7.13%. On a year-on-year basis, the BBR has decreased by 0.75%, but the average SVR has only fallen by 0.55%, indicating a widening gap between base rates and what consumers actually pay.
The Moneyfacts Average Mortgage Rate has declined over the past year from 5.33%; last month the rate stood at 4.90%, but it has recently surpassed the 5% mark, reflecting the current upward pressure on borrowing costs.
Finance Expert Explains Market Dynamics
Rachel Springall, a finance expert at Moneyfactscompare.co.uk, provided context for these developments: "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 their margins very carefully, so it would be unwise to price their deals too low if expectations are for interest rates to rise, even over the short term."
Springall continued: "The mortgage market needs stability and, realistically, borrowing costs remain lower than in recent years. We have enjoyed sub-4% deals on the shelves for over a year since February 2025. While many of the biggest lenders no longer offer a sub-4% fixed deal, this represents a cautious and prudent decision."
Global Pressures Drive Rate Increases
"Mortgage rates are rising due to global pressures rather than UK fiscal policy specifically," Springall explained. "While not ideal for borrowers, these rate increases do not mirror the 'mini-Budget' fiasco that occurred in 2022."
In an unprecedented turn of events, ongoing unrest in the Middle East has led directly to rising swap rates, which have subsequently inflated mortgage rates and caused numerous deals to be pulled from sale, some temporarily. These global developments have effectively scuppered expectations that the Monetary Policy Committee would vote for a cut to the Bank of England Base Rate, making a hold on current rates much more likely this week.
Future Uncertainty and Borrower Advice
Springall offered a sobering assessment of potential future developments: "If such uncertainty is prolonged, and indeed if inflation spikes significantly, we could even see an increase to BBR before the year is over. It really is too early to predict what might happen with certainty, but borrowers searching for a new deal should seek professional financial advice if they are concerned about rising costs."
The finance expert emphasized: "It remains critically important to secure a fixed deal compared to reverting to a high standard variable rate. Our calculations show that nearly £300 could be saved each month in repayments by choosing a fixed product. Additionally, existing borrowers could potentially lock into a new deal up to six months in advance of their current term ending."
Moneyfactscompare stated that the £300 saving figure was calculated using the average standard variable rate (SVR) currently at 7.13%. These calculations were based on a £250,000 mortgage over a 25-year term on a standard repayment basis. Specifically, SVR repayment would cost approximately £1,787 monthly, compared to just £1,502 monthly on a 5.28% two-year fixed rate product.
