UK 30-Year Gilt Yields Hit 6% as Global Bond Market Sell-Off Intensifies
A severe sell-off across international bond markets has intensified, sending government borrowing costs sharply higher in Britain, the United States, and Asia. Prices for sovereign debt have fallen rapidly, pushing the yield on Britain's 30-year gilts to 6% for the first time since 1998. Yields on shorter-dated UK government debt also increased, mounting financial pressure on Chancellor John Healey as preparation continues for the upcoming budget.
The bond market rout is being propelled by renewed inflation anxieties linked to energy market disruption. Ongoing conflict in the Middle East continues to constrain regional oil supplies, while reports that Chinese refiners have suspended exports of petroleum products outside Hong Kong and Macau have exacerbated supply fears. International crude prices rose steeply in response, with Brent crude advancing 2.7% to reach $100.66 a barrel. Adding to European market concern are reports that the US administration has requested Germany and France draw down emergency diesel stocks to stabilize prices or face potential restrictions on US diesel exports.
In the United States, 10-year Treasury yields rose to their highest level since 2002. Bond yields remained elevated despite softer US inflation readings, as market participants maintained expectations that the Federal Reserve will hold interest rates higher for longer to combat stubborn price pressures.
The Guardian reportedly quoted Axel Rudolph (chief technical analyst at investing and trading platform IG) as saying: “US bond yields are refusing to budge, with the 10-year yield hitting its highest level since 2007 despite softer-than-expected inflation. While the latest data has reduced expectations of an October Fed rate hike, investors remain wary that persistent inflation and higher oil prices could keep rates elevated for longer.”.
Slowing manufacturing and currency pressure
Domestic economic indicators offered little relief to British markets. S&P Global reported that output growth across UK manufacturing slowed for a second consecutive month in September, reaching its weakest expansion rate in six months amid modest order and export growth. Crucially for debt markets, factory operators reported that input price inflation accelerated for the first time in four months, forcing manufacturers to raise their own prices.
The Guardian reportedly quoted Rob Dobson (director at S&P Global Market Intelligence) as saying: “A disappointing September PMI saw the rate of increase in UK manufacturing production slow further.”.

Equity and currency markets reacted sharply to the fixed-income volatility. The US dollar strengthened against a basket of currencies, surging to a three-month high and driving the euro down to a 17-month low below $1.13. On the London Stock Exchange, the FTSE 100 experienced broad losses, led by declines in tabletop gaming company Games Workshop alongside housebuilders and banking stocks.
