UK Gilt Yields Reach Highest Levels in Decades

UK borrowing costs reached their highest in decades on 14 September 2026. Yields on 10-year gilts — UK government bonds — passed 5.4%, the highest since July 2007, while 30-year yields rose to 5.93%, the highest since March 1998. That means higher state borrowing costs ahead of Chancellor John Healey's October budget.
