Interest rates were on the rise long before Mr Kwarteng’s fiscal statement. On January 31st the average rate on new mortgages was 1.59%; by August 31st that had risen to 2.56%. But recent increases have been much faster. Between September 1st and October 3rd expectations for where the Bank of England’s base rate, which influences mortgage rates, will be in two years rose by 1.5 percentage points. Andrew Wishart of Capital Economics, a consultancy, expects average new mortgage rates of 6% in the first quarter of next year (see chart). That would be the fastest annual jump since 1989.
The risk is that this jump in rates will set off a nasty downward spiral. Some people may be unable to keep repaying their mortgages, prompting a rise in repossessions. Mr Wishart predicts arrears to rise from 0.7% of mortgages now to 1.6% in 2024. Rather than falling behind on dearer mortgage payments, other households will pull back on spending elsewhere. Prospective buyers will find themselves unable to afford what they could before. That, combined with a darkening macroeconomic backdrop, will push down house prices, making homeowners feel poorer and further crimping their spending.
Some reassurance comes from the fact that lending standards have been relatively stringent, at least compared with those before the global financial crisis of 2007-08. For example, stress-testing to see if borrowers can withstand a big change in their mortgage rate has been much more common. Because house prices have risen by over 25% since June 2020, it would take a large correction to propel lots of borrowers into negative equity. Those unfortunate enough to be struggling with their interest payments should get a sympathetic reception from their banks, who do not want the bad press of evicting people.
Even so, higher interest rates will hurt. Mr Wishart expects average mortgage costs to grow from 2% of total household income to over 5% by mid-2024. That shock will be concentrated on the third of British households that have an outstanding mortgage on a home they own. Neal Hudson of Residential Analysts, a consultancy, reckons that currently around 300,000 mortgages each quarter are coming to the end of their fixed-rate period, rising to 375,000 in the second quarter of next year. Yet even for those who do not have to remortgage immediately, spending now will be dampened in anticipation of much higher bills in future.
