UK mortgage resets move to the center of the bond selloff

Mortgage pricing has followed the curve higher

UK mortgage pricing is closely tied to two- and five-year swap rates, rather than the long fixed-rate mortgage structures common in the US and parts of Europe.³ That makes UK households unusually sensitive to shifts in market expectations for Bank Rate and funding costs.

The selloff has been large enough to reprice both the gilt curve and mortgage shelves. Thirty-year gilt yields topped 6% on October 1 for the first time since 1998 before easing. After a rally in gilts, two-year yields were still around 4.69% and 10-year yields around 5.32% on October 2.⁴ Reuters also cited a 27 basis-point monthly rise in the two-year SONIA swap rate to 4.68%, adding roughly a third of a percentage point to fixed-rate funding costs.³

Mortgage trackers show that repricing is reaching borrowers. Rightmove’s October 2 data put the average two-year fixed mortgage rate at 5.54% and the average five-year fixed rate at 5.51%, both up 5 basis points on the week and roughly 1 percentage point higher than a year earlier.¹ HomeOwners Alliance, citing Moneyfacts, put the average two-year fixed rate at 5.93% and the five-year fixed rate at 5.95% on October 1.²

The most important shift is not just the average rate. It is the disappearance of cheaper refinancing options. HomeOwners Alliance said the number of sub-5% products had collapsed from about 630 two-year fixes and 638 five-year fixes at the start of September to just five and seven, respectively, by September 30.² PropertyWire also reported that major lenders had been withdrawing products below 5%, with average two-year rates at their highest since July 2024 and average five-year rates at their highest since October 2023.⁷

The refinancing pipeline is now a macro variable

The UK mortgage market has a built-in lag. Many households fixed at very low rates during the pandemic and feel the shock only when those deals expire. That means the economic impact of higher yields arrives in waves.

The Bank of England estimate cited by Reuters — more than 5 million households facing higher repayments by the end of 2028 — is the broad pipeline.³ The more acute group is the roughly 750,000 borrowers resetting from pre-2022 fixed rates this year, with an average increase of £170 a month.³

Annualised, that is about £2,040 of additional mortgage cost per affected household. Across 750,000 households, the cash-flow drag is roughly £1.5 billion a year before allowing for any further rate increases or larger individual shocks.

That estimate is deliberately narrow. It covers the acute 2026 reset cohort cited by Reuters, not the full group due to face higher payments by the end of 2028. It also excludes indirect effects such as weaker housing turnover, lower spending by prospective buyers saving for larger deposits and tighter affordability tests.

For equity investors, the key point is that refinancing pressure acts like delayed tightening in household financial conditions. It can continue even if the Bank of England is on hold, as long as swap rates and gilt yields keep mortgage funding costs elevated.

Housing demand is already softening

The housing channel is the first place to look. Higher mortgage rates reduce affordability, lower the maximum loan size available under lenders’ stress tests and make potential sellers more reluctant to move if doing so means giving up an old cheap mortgage.

Reuters reported that UK mortgage approvals have fallen to their lowest level since the end of 2023, signalling weaker demand as borrowing costs rise.³ Nationwide data reported by Reuters showed house prices unexpectedly fell 0.2% month on month in September, while annual growth slowed to 0.8% from 1.6% in August, the weakest pace since December 2025.⁶

The risk is not necessarily a sharp nominal house-price fall. Supply shortages may cushion prices, and Capital Economics still expected UK house prices to rise 2.5% in 2027, according to Reuters.³ The larger near-term risk is lower transaction volumes.

That matters for estate agents, portals, housebuilders, furniture retailers, DIY chains, mortgage lenders and insurers — the broader housing ecosystem whose revenues depend on activity, not just prices.

Consumer spending is the second-round effect

The second channel is consumer demand. A £170 average monthly increase for 750,000 resetting borrowers is a direct hit to discretionary cash flow.³ The effect is likely to be uneven. Higher-income households may absorb the increase through savings, while highly leveraged households and first-time buyers may cut spending more aggressively.

The backdrop is not benign for margins. The Bank of England’s September Decision Maker Panel showed firms still expected year-ahead own-price inflation of 3.7%, annual wage growth of 4.0% and year-ahead wage growth of 3.4%. It also found that 70% of firms expected lower profit margins over the next 12 months as a result of the recent energy shock.⁸

That combination — higher household debt service, sticky prices and pressure on business margins — is awkward for domestic-facing equities. Retailers, pubs, restaurants, leisure operators and small-cap consumer cyclicals are exposed to any fall in discretionary spending. Banks may benefit from higher rates in theory, but mortgage affordability constraints, lower loan growth and credit-risk concerns can offset that benefit.

UK equities are already pricing part of the transmission

The equity market has started to connect the dots. Reuters reported that the FTSE 100 fell 2.2% for the week ended October 2, its steepest weekly drop since April, as the bond rout dented risk appetite.⁵ The FTSE 250 — a better gauge of domestically oriented UK earnings — ended the week marginally lower, while rate-sensitive homebuilders bounced only after a previous 5% drop.⁵

Banks also remained under pressure, with the UK lenders index suffering its biggest weekly decline since April.⁵ That is consistent with a market beginning to view higher yields as a mixed earnings signal: positive for asset yields, negative for loan demand, affordability, credit quality and housing volumes.

The distinction matters. If rising yields were only a gilt-market event, equity investors could treat the shock mainly as a discount-rate adjustment. If rising yields become a household cash-flow event, the earnings channel broadens to domestic consumption, mortgage volumes, arrears risk, housing transactions and small-cap demand sensitivity.

What to watch next

The most important indicators are now household-facing rather than purely market-facing. Two- and five-year swap rates will show whether lenders have room to reintroduce cheaper fixed deals. Mortgage approvals and housing transactions will reveal whether buyers are stepping back. Retail sales, card spending and consumer confidence will indicate whether refinancing pressure is bleeding into broader demand.

For markets, the risk is that the gilt selloff has already moved from balance sheets to bank accounts. The refinancing wall through 2028 means the UK economy may continue to absorb the yield shock long after the most dramatic moves in the gilt curve have passed.
