Moneyfacts’ rate watch data shows severe increases since last Friday, but the movements have not yet been as steep as they were following the Liz Truss mini-Budget.

Back then, in September 2022, average two-year fixed rates jumped by 181bps in a single week.

Over the past week, the average two-year fixed has climbed 40bps higher to reach 5.75%.

This is 92bps higher than it was just before the outbreak of war in Iran.

The average five-year fixed is 30bps higher than last Friday, at 5.69% today.

Average three-year fixed rates at 65% LTV saw the steepest weekly increase, of all categories, rising by 58bps to 5.19%.

Average two-year fixed rates at 50% LTV soared by 57bps to 5.48%.

Most other product tiers saw week-on-week increases of 40-50bps.

The Chancellor met with the six largest lenders to confirm mortgage support for borrowers amid the ongoing turmoil.

Moneyfacts head of consumer finance Adam French says: “Rates aren’t moving as quickly as we saw in response to the mini-Budget.

“However, the longer the conflict grinds on and global supply chains remain heavily disrupted the closer we may get to reaching the levels of increases we saw then but over a longer timeframe.

“The average rate on a two-yr fix has only increased by around half the amount it did over a similar timeframe in response to the mini-budget. 

“Back then rates calmed and fell away a bit before rising again as Base Rate rose over the next couple of years. 

“The path to a calmer market today is less clearcut.”

He adds: “Rapid repricing, withdrawals and the selective relaunching of products all point to a market still scrambling to keep pace with higher funding costs. 

“Mortgage pricing is moving quickly and does not wait for the Bank of England to act. 

“As long as the money markets continue to price in higher interest rates due to the ongoing conflict in the Middle East, lenders will need to keep adjusting their ranges.”
