Part of situation: UK gilt market volatility and economic risk (11 clusters)

UK gilt yields surge to highest levels since 1998

UK gilt yields government bonds borrowing costs inflation UK Budget

UK government borrowing costs have surged as gilt yields reached multi-decade highs. On October 1, 2026, the yield on 30-year government bonds climbed above 6%, the highest level recorded since January 1998. Additionally, the 10-year gilt yield rose to approximately 5.51%, marking its highest point since July 2007.

The spike in yields is attributed to a global bond market sell-off driven by persistent inflation concerns, high energy prices, and uncertainty regarding future interest rate paths. This volatility has also impacted equities, causing the FTSE 100 Index to drop by 2%.

The rising costs present significant fiscal challenges for Chancellor John Healey ahead of his upcoming Budget. Increased yields are expected to raise government debt interest payments, with economists suggesting a one percentage point rise in rates could add £15bn in costs by 2031. Some analyses indicate these rising rates could reduce the government's fiscal headroom by approximately £9bn. The Bank of England has also noted potential market vulnerabilities, including high leverage among certain hedge funds and growing debt associated with the artificial intelligence sector.
