What is driving the global bond sell-off—and how does it reach the wider economy?

The US 10-year Treasury yield reached 5.34%, its highest since 2002, after recording its biggest quarterly increase this century, while selling pressure spread through France, Britain and Japan.[1][4] The yield later retreated toward 5.25% as bargain buyers entered the market and Federal Reserve officials signaled patience over additional rate increases; US stocks consequently recovered from early losses to close slightly higher.[3][5][6] Why it matters: Higher sovereign yields raise financing costs for governments, companies and mortgage borrowers, tighten financial conditions and reduce the relative appeal of stocks; advanced economies already paid more than $3.3 trillion in interest on internationally traded government bonds over the past year.[4][5] Key insights: The sell-off has several reinforcing drivers: elevated oil prices are feeding inflation concerns, AI and data-center construction are increasing demand for capital, and resilient economic activity is supporting expectations that interest rates will remain higher for longer.[1][4] | Europe is a particular pressure point: French 10-year borrowing costs approached 5%, the spread over German debt was near its widest since the euro-zone debt crisis, and Britain’s 30-year yield exceeded 6% for the first time since 1998.[4] | The reversal showed how sensitive equities are to bond yields: the S&P 500 recovered from a two-week low and closed 0.2% higher after the US 10-year yield pulled back, while AI-linked shares provided additional support.[5][6] | Near-term Federal Reserve expectations have softened despite the long-term yield surge: markets assigned a roughly 28% probability to an October rate increase, down from about 69% a week earlier.[2][6] Cheatsheet facts: What changed: The US 10-year yield touched 5.34%, its highest since 2002, before retreating toward 5.25%; comparable selling pushed borrowing costs in France, Britain and Japan to multi-decade highs.[1][3][4] | Why now: Higher energy costs, persistent input-price pressure, strong economic activity, government borrowing needs and capital demand from AI infrastructure are collectively increasing inflation and interest-rate expectations.[1][4][5][6] | Watch next: Track the published US payroll, unemployment and wage-growth figures, alongside oil prices and the US 10-year yield; markets are using those observable indicators to judge whether the Federal Reserve can delay further tightening.[2][3]
