Why British homeowners feel rate rises faster than anyone

Two-year gilt yields are climbing toward 5.5 per cent, their highest since 2008, and British homeowners are feeling it faster than borrowers almost anywhere else in the rich world. Monetary policy rarely bites evenly across advanced economies. In Britain it bites the household first, and the reason is the short life of the typical mortgage.

A half-point surprise

The latest leg of the sell-off began with the inflation data. Consumer prices rose 8.7 per cent in the year to May, and core inflation climbed to 7.1 per cent, its highest since 1992. The Bank of England responded on 22 June by lifting Bank Rate by half a point to 5 per cent, a bigger step than most economists had expected. Markets took the move as a sign that more was coming and repriced the whole short end of the gilt curve upwards.

The two-year yield matters to households because it anchors the swap rates that lenders use to price fixed-rate mortgages. When it jumps, banks and building societies reprice their products within days, and some pull them from sale altogether while they work out new rates. Borrowers saw the same thing last autumn, when the September mini-budget sent gilt yields soaring and hundreds of mortgage products vanished overnight. This time the cause is domestic inflation rather than fiscal credibility, which makes the adjustment harder to reverse.

Two-year fixes, quick pain

American homeowners locked in thirty-year mortgages at three per cent. British borrowers depend almost entirely on fixed deals lasting two to five years. When those deals expire, hundreds of thousands of households roll straight onto whatever the market now charges. The jump in monthly payments comes directly out of spending money. It skips corporate profits altogether and lands on the high street.

The mechanics are brutal for anyone who fixed during the era of near-zero rates. A borrower who took a two-year deal in mid-2021 was paying a rate that began with a one or a two. The replacement deal on offer this summer carries a rate several points higher, and on a typical repayment mortgage that can add hundreds of pounds a month. Those who fail to arrange a new deal in time drop onto their lender's standard variable rate, which is higher still.

Why America is insulated

The contrast with the United States is not an accident of taste. American mortgage finance rests on long fixed-rate loans that can be refinanced without penalty when rates fall, backed by government-sponsored agencies that buy and guarantee them. Millions of households refinanced in 2020 and 2021 at rates close to 3 per cent and will keep those rates for decades unless they move. For them, the Federal Reserve's tightening shows up mainly as a reason not to sell their house.

That shields American consumption but freezes the housing market, since owners with cheap loans are reluctant to give them up. Britain has the opposite problem. Its housing market keeps turning over, but each turnover and each refinancing drags current rates into household budgets. The same policy rise that trims American spending over years trims British spending over months.

Lessons from 1990

Britain has been here before, in a harsher form. At the end of the 1980s most British mortgages were on variable rates, and when base rates reached 15 per cent in 1989 and stayed there for a year, payments rose almost immediately. Repossessions surged in the early 1990s, house prices fell for several years, and consumer spending contracted. The rise in fixed-rate lending since then has been partly a response to that experience.

The current episode is milder because the fixes buy time and because lenders have been obliged since the post-2008 reforms to check that borrowers could cope with considerably higher rates. The time bought is short, however. A market built on two- and five-year fixes spreads the shock across a few years rather than absorbing it, and the queue of expiring deals is long.

Who feels it, and who does not

The heaviest burden falls on younger households who bought recently with large loans relative to income, often in London and the South East. Buy-to-let landlords with interest-only mortgages face an even sharper rise in costs, and many will try to pass it on in rents, spreading the pain to tenants who own no property at all. Outright owners, disproportionately older, are untouched and may even benefit as savings rates climb.

The government has so far resisted direct subsidies. Instead, the Chancellor, Jeremy Hunt, agreed a mortgage charter with the main lenders in late June that lets struggling borrowers switch temporarily to interest-only payments or extend their terms, and delays repossessions. Those measures ease cash flow at the margin. They do not change the price of money, and a longer term means more interest paid in total.

The argument for resilience

There is a fair counterargument. Households built up savings during the pandemic, employment remains high, and a large share of owner-occupiers have no mortgage at all. Many borrowers have also moved to five-year fixes in recent years, which means a smaller slice of the stock reprices in any single year than the two-year model implies. On this view the squeeze will be real but manageable, a drag on growth rather than a recession.

That is plausible for the economy as a whole, but it misses where the spending comes from. The households rolling off cheap fixes are disproportionately working-age families who spend most of their income, and their extra mortgage costs come out of restaurants, clothes and holidays rather than savings. The aggregate figures will soften the story; the retail and hospitality data are likely to tell it more plainly.

The signals to watch are the monthly inflation figures, the Bank's August decision, mortgage approvals, and UK Finance's figures on arrears. Because British mortgages reset every few years, a rise in policy rates reaches household budgets almost at once, and high-street spending will take the hit well before it does in America. The damage should show up in retail sales and consumer confidence over the second half of this year, with younger mortgaged families and their landlords' tenants paying most of it.
