The UK government has paid the highest interest rate on 10-year debt since 1999 at a bond auction, with investors demanding a yield of 5.383%. This milestone reflects growing concerns over inflation and fiscal policy, impacting mortgages and rate cut expectations.
UK Government Pays Highest Yield Since 1999
At today's auction, the Debt Management Office sold debt maturing in 2036 at an average yield of 5.383%, the highest since 1999. This surge in borrowing costs signals investor reluctance to hold long-term UK debt amid economic uncertainty.
Evelyne Gomez-Liechti, a strategist at Mizuho International, noted, "The auction was on the weaker side, adding to the narrative that investors continue to be reluctant to add duration here despite attractive yield levels."
Impact on UK Mortgages and Homebuyers
Demand for UK mortgages has slumped to a 32-month low, with only 54,918 new home purchase mortgages approved in August—the lowest since December 2023. Rising mortgage rates, linked to the war in Iran and soaring oil prices, have deterred buyers and dashed hopes of interest rate cuts.

- Mortgage approvals plummet: 54,918 in August, a 32-month low.
