Coventry Building Society has become the first mainstream UK lender to confirm mortgage rate increases, responding to rising bond yields and swap rates that are squeezing lenders' funding costs. The mutual announced hikes across its entire fixed-rate mortgage range, marking a significant shift in the housing market.
The move comes after Prime Minister Andy Burnham's recent speech, amid reports that investors fear a Liz Truss-style market meltdown unless he presents a credible plan to fund his agenda. UK borrowing costs have surged to multi-decade highs this week as part of a global bond market sell-off, with investors warning of further spikes unless the government outlines tax rises or spending cuts.
Market Pressure and Fiscal Concerns
According to The Telegraph, investors are particularly concerned about Burnham's fiscal agenda ahead of his first Budget next month. At his first Prime Minister's Questions on Wednesday, Burnham refused to rule out increasing borrowing despite the recent market turmoil.
Mortgage brokers say the rate rises were widely anticipated. Justin Moy, Managing Director at Chelmsford-based EHF Mortgages, said: "The warning most mortgage brokers gave at the start of the week has come true, with mortgage lenders having little choice but to raise mortgage rates as borrowing costs rise."
Moy added: "It's become a race to the top; borrowers need to be aware and act quickly to secure deals, especially those looking to remortgage in the coming months, particularly those on 1-2% rates from 2022. There is little to suggest improvements are on the horizon. The October Budget needs to be a belter to save 2026, and the government."
Broker Reactions and Borrower Advice
Stephen Perkins, Managing Director at Norwich-based Yellow Brick Mortgages, said: "Coventry's move is another reminder that fixed mortgage rates can change quickly as wholesale funding costs move. Borrowers approaching the end of a deal should review their options early, but not panic."
Perkins added: "Securing a suitable rate in advance can protect against further increases while still leaving time to reassess if the market improves. One lender moving doesn't mean every lender will do the same, so comparison remains important."
Harry Goodliffe, Director at Winchester-based HTG Mortgages, said: "Coventry has done everyone a favour by going first. Swaps have jumped as bonds climb and the Middle East kicks off again, so the sums behind last week's deals simply stopped working."
Investor Warnings and Outlook
Goodliffe continued: "Coventry moving now tells borrowers what the next fortnight looks like before the bigger names admit it. Expect a run of repricing notices over the coming days, and rate offers already secured will look very good very quickly."
Al Cattermole, a portfolio manager at Swiss private bank Mirabaud, said: "If you have a lack of credibility about your spending plan and how that will be funded, then you would get spikes in yields similar to [what] we saw during the Liz Truss episode. That was about unfunded fiscal spending. And if you get that again, then there is concern about that."
The October Budget will be a key test for Burnham's fiscal credibility, with investors closely watching for concrete funding plans. Meanwhile, borrowers with fixed-rate deals expiring soon face higher costs as lenders adjust to the new market conditions.
