Dariusz Karpowicz, director at Doncaster-based Albion Financial Advice, also emphasised how quickly markets - and mortgage pricing - can turn: "For weeks, the direction felt obvious: rates were falling, a Bank of England cut looked nailed on and everyone got comfortable.

"Then geopolitical risk reminded us that comfort is temporary. Coventry and HSBC repricing is likely the first domino, not the last. The real question is whether this is a blip or a shift."
