Global bond markets tumbled further on growing concern that fiscal and commodity pressures could force central banks to tighten policy, pushing the yield on the UK’s 30‑year gilt above 6 percent for the first time since 1998.
Investors said fears about the size and durability of the US budget deficit have contributed to the rout, prompting a reassessment of the outlook for long‑dated government debt worldwide. The move higher in UK long‑term yields, which equates to a 28‑year high, reflects broader nervousness about sovereign borrowing costs and demand for safe assets.
Market participants also pointed to persistently high oil prices as a key factor. Rising energy costs are stoking worries that inflation will pick up again, and many investors now expect central banks to respond with further interest‑rate increases to prevent higher prices from becoming entrenched.
The combination of fiscal concerns and renewed inflationary pressure has led to a reassessment of rate expectations and risk premia across fixed‑income markets. Analysts said the speed of the sell‑off has exacerbated moves in long maturities, where duration risk is greatest.
While the immediate focus is on yields and monetary policy prospects, the broader implications include higher borrowing costs for governments and potentially for businesses and households as long‑term interest rates rise. Market observers will be watching data and policy signals closely for indications of whether the sell‑off will stabilise or continue to widen.
Traders cautioned that volatility could persist as investors digest fiscal developments in the United States, oil market dynamics and any central bank commentary that might alter expectations for the path of interest rates.
