The yield on the US 30-year Treasury bond surged past 5.33% on Tuesday, reaching its highest level since 2007 and capping a global bond selloff that has sent shockwaves through financial markets worldwide. The milestone marks the apex of a months-long climb in long-dated borrowing costs driven by stubborn inflation, an expiring Middle East ceasefire, and deepening concern about the US fiscal trajectory. The 10-year yield also pushed higher, settling near 4.74%, its highest since early 2025.
Why Yields Are Surging
Analysts pointed to a confluence of factors behind the sell-off. The 60-day US-Iran ceasefire expired Monday without a successor deal, sending crude oil higher and reviving fears that energy-driven inflation could prove stickier than central banks had hoped. “Investors priced in a more extended closure of the Strait of Hormuz due to a lack of progress on a US-Iran deal,” said Jim Rid, a strategist at Deutsche Bank. Oil’s rally has amplified concerns that inflation, which has run above the Federal Reserve’s 2% target for five straight years, may re-accelerate just as the Fed was expected to begin easing policy. The CME FedWatch Tool now prices roughly a 70% probability of at least one rate hike before year-end, up sharply from a week ago. The US fiscal picture has added fuel. The Treasury reported a $432.3 billion deficit in July alone, pushing the year-to-date shortfall to nearly $1.8 trillion. With the national debt approaching $40 trillion and annual interest payments topping $1.2 trillion, investors are demanding ever-higher compensation to hold long-dated government paper.
Global Spillover
The selloff is decidedly global. Japan’s 10-year government bond yield climbed to 2.93%, its highest level in roughly 30 years, as the Bank of Japan continues its slow exit from ultra-loose monetary policy. The prospect of Japanese institutional investors repatriating capital from overseas bond markets to capture rising domestic yields is adding further pressure on US Treasuries. Germany’s 30-year Bund yield hit its highest level since 2011, while France’s comparable yield reached a post-2008 high. The synchronized move reflects a broader reassessment of sovereign risk and inflation expectations across advanced economies. “Bond markets are warning that inflation could prove much stickier than many investors anticipated,” said Nigel Green, CEO of deVere Group.
Stock Markets Under Pressure
Equities have borne the brunt. The S&P 500 fell for a third straight session on Monday, closing at 7,745, while the Dow Jones Industrial Average dropped 273 points. The Nasdaq Composite shed 0.32%. In Asia on Tuesday, South Korea’s KOSPI briefly surged above 7,000 before reversing sharply, closing at 6,870 after a 428-point intraday swing driven by the yield spike. Tech stocks were hit hardest, with memory chipmakers SK Hynix, SanDisk, and Western Digital each falling more than 5% on fears that rising borrowing costs could slow data center expansion. “Inflation remains in the driver’s seat for stocks,” said Kevin Gordon, head of macro research at Schwab’s Center for Financial Research. He noted that bond yields and stocks now have the most negative correlation since 1997, meaning when one rises the other falls.
Gold, Dollar, and the Week Ahead
Gold traded near $4,471 per ounce, up from its year-to-date low of $3,955 in July but well below the 2026 high of $5,627. The precious metal has struggled to maintain its traditional safe-haven role as rising real yields increase the opportunity cost of holding non-yielding assets. The US Dollar Index slipped to 99.59, off recent highs above 101. Market attention now turns to the release of FOMC meeting minutes on Wednesday afternoon, which could shed light on whether Fed officials discussed the possibility of a rate hike. Earnings from Walmart, Target, Lowe’s, and Alibaba later this week will provide further clues on consumer resilience and corporate margin pressures.
