Santander Confirms Second Mortgage Rate Increase, Effective Tuesday
Santander has delivered unwelcome news to its mortgage customers, confirming a second round of rate rises that will take effect from Tuesday, March 17, 2026. The banking giant announced the increases on Saturday, leaving many borrowers frustrated and concerned about their financial plans.
Details of the Rate Changes
The new rates will impact several key mortgage products, including new business first-time buyer mortgages, home mover loans, large loan products, remortgage deals, and buy-to-let mortgages. Santander is increasing these rates by up to 0.35%, marking a significant adjustment that follows a previous 0.24% increase earlier in the same week.
This latest move has sparked concern among mortgage brokers and financial experts, who warn that the cumulative effect of these increases could have serious consequences for the housing market and individual borrowers.
Industry Reaction to Santander's Announcement
Stephen Perkins, Managing Director at Norwich-based Yellow Brick Mortgages, expressed his dismay at the timing and implications of Santander's announcement. "The bad news for borrowers just keeps piling up," Perkins stated. "This news from Santander so late on a Friday suggests we can expect more of the same next week."
Perkins further explained, "The rate increases we're now seeing and their impact on potential payments are such that we may see home buying or moving plans shelved. Hopefully, this will be a short-term blip that will blow over once stability is restored in the geopolitical landscape. But for now the mortgage market is extremely volatile and lenders' nerves are fraught."
Craig Fish, Director at London-based Lodestone Mortgages, echoed these concerns, noting, "Just when brokers thought the worst was over, Halifax and Santander have torpedoed the week. We've had rate hikes across the board: new business, product transfers, buy-to-let, the lot."
Fish emphasized the significance of the increase, stating, "Up to 0.35% in a single move from Santander on top of the 0.24% earlier in the week suggests this isn't a blip. Swap rates have surged on the back of Middle East tensions and markets are rowing back hard on Bank of England rate cut expectations."
He added a stark warning about the current market conditions: "Lenders are repricing fast and furiously to protect margins. The green shoots we'd carefully nurtured through early 2026, with sub-4% deals, cautious optimism and clients finally ready to act have been torched in a matter of days. It feels uncomfortably like 2022 all over again. The advice right now is simple: don't wait, don't speculate. Act."
A Different Perspective on Santander's Actions
Not all feedback was entirely negative. Justin Moy, Managing Director at Chelmsford-based EHF Mortgages, offered a more nuanced view of Santander's approach. "Santander actually repriced downwards on that weekend of the conflict, and held some very low rates for a week and a half before the increase last Wednesday, and those announced tonight that will start from Tuesday 17th," Moy explained.
He continued, "Most lenders have suffered similar issues with pricing but at least Santander held their cheaper rates longer and have given a few days notice of this latest round of changes. Credit where credit is due to Santander."
Broader Implications for Borrowers and the Market
The consecutive rate increases from Santander reflect broader volatility in the mortgage market, driven by geopolitical tensions and shifting expectations regarding Bank of England policy. These developments are forcing lenders to adjust their pricing strategies rapidly to maintain their profit margins.
For potential homebuyers and those looking to remortgage, these changes mean higher monthly payments and potentially altered financial plans. The timing of Santander's announcement, coming late on a Friday, has added to the uncertainty facing borrowers who must now navigate these new rates effective from Tuesday.
As the mortgage market continues to experience significant fluctuations, experts advise borrowers to stay informed and consider acting promptly rather than waiting for further changes. The situation remains fluid, with industry professionals monitoring developments closely for any signs of stabilization or additional rate adjustments from other major lenders.
