UK 30-Year Gilt Yields Surge Past 6% for First Time Since 1998

Britain's 30-year government bond yields climbed above 6% on October 1, 2026, marking the highest level since January 1998, according to reports from the Daily Mail. The longer-dated gilt yield reached as high as 6.029%, reflecting a broader global selloff in bond markets that has also pushed up US Treasury yields.

The increasing cost of borrowing is a significant concern for the UK government, particularly for Chancellor John Healey as he prepares to deliver his inaugural budget. Higher yields translate to increased government expenditure on debt financing, potentially limiting funds available for public services such as defense, social care, and housing.

Analysts note that the rising yields are exerting pressure on equity markets as well. The FTSE 100 index saw a significant drop, falling 1.7% in early trading, while the FTSE 250 also experienced a decline. Similar downturns were observed in European markets, with Germany's Dax and France's Cac indices both falling.

This development follows a recent 10-year gilt auction where the government paid the highest yield since 1999, underscoring the growing expense of government borrowing. Experts suggest that sustained high yields could further constrain the Chancellor's fiscal flexibility when outlining spending plans.

The bond market selloff is occurring even as oil prices have stabilized due to renewed hopes for an end to the Iran war. The UK already faces some of the highest borrowing costs among G7 nations, with its 10-year gilt yield climbing to 5.509%, its highest point since July 2008. The 5-year gilt yield also reached an 18-year high.
