Two more big lenders have announced increased fixed rates on mortgages this morning, with NatWest and Santander following Halifax's move at the end of last week.
Natwest has announced a hike across the full range of residential and buy-to-let products from tomorrow and Santander also unveiled a suite of rate increases for both fixed and tracker by up to 0.25% from Tuesday too.
NatWest said rates on new business would move up to 0.22% higher.
Later in the day Nationwide made it three of the UK's 'big six' lenders, with the building society announcing up to 0.25% of higher mortgage rate increases across its fixed rate range, for movers and remortgages, plus those for existing borrowers looking for a new deal.
The hikes were not unexpected, following more rises from rivals in recent weeks, said Justin Moy of EHF Mortgages.
"With the likelihood of base rate cuts becoming less likely in 2024, longer-term swap rates have continued to increase over the past few weeks, lenders have had little choice other than to follow," he said. "Where will this stop? Low inflation and a general election don't seem enough to make a difference."
Stephen Perkins, managing director at Yellow Brick Mortgages, added: "The market is doing its best to douse the remaining optimism of potential buyers, hopefully this will not extinguish their hope in buying a property."
The news is grim for householders trying to get their budgets under control, said Gary Bush, a financial adviser at MortgageShop, saying this "doesn't seem likely in the short term sadly. Hang onto your hats homeowners the bumpy ride continues."
