The yield on the 10-year U.S. Treasury note climbed to 5.34% on Thursday morning, its highest level since April 2002, signaling that borrowing costs for consumers and businesses are set to rise further. The yield has since eased slightly to around 5.32% by midmorning, but remains up roughly 3 basis points from Wednesday's close.
The surge in yields over the past seven months has been driven by a combination of persistent inflation, elevated energy prices, and growing government debt. The 10-year yield closed at 3.96% on Feb. 27, the day before the U.S. and Israel launched military action against Iran. That conflict has disrupted shipping through the Strait of Hormuz, pushing energy prices higher and adding to inflationary pressures in the U.S. economy.
According to the Bureau of Economic Analysis, the annual inflation rate as measured by the personal consumption expenditures price index stood at 3.4% in August. Meanwhile, AAA data shows the national average price for a gallon of regular gasoline is approximately $4.41, a jump of $1.43 from two days before the conflict began.
The federal government's ballooning debt is also contributing to the global rise in bond yields. The national debt surpassed $40 trillion in August and now stands at roughly $40.1 trillion, increasing the supply of Treasuries that must be absorbed by the market.
The 30-year Treasury bond, which typically offers a higher yield than shorter-term securities, has also risen on Thursday, trading at about 5.67% as of midmorning—its highest level since April 2002. This upward movement in long-term yields is pushing up borrowing costs across the economy, including for home mortgages. The average 30-year fixed-rate mortgage hit 7.03% last week, exceeding 7% for the first time since January 2025, according to Freddie Mac.
Federal Reserve officials have pointed to another factor behind the bond market sell-off: the rapid expansion of artificial intelligence data centers and models. Wall Street's recent rebound has been tempered by these persistent yield pressures. Fed Governor Lisa Cook noted on Monday at a technology conference in Oakland, California, that "data center investment relies on inputs, like construction labor and energy, that are broadly used in many sectors in the economy. As a result, increased AI investment could introduce price pressure to those other sectors."
The implications for U.S. households are significant. Higher yields on Treasuries translate directly into more expensive loans for homes, cars, and business investments. With inflation still running above the Fed's 2% target and energy costs elevated, the central bank faces a delicate balancing act between curbing price growth and avoiding an economic slowdown.
Investors are also watching how the political debate over fiscal policy and spending might affect the trajectory of government debt. The combination of high debt issuance, persistent inflation, and AI-driven energy demand suggests that bond yields may remain elevated in the near term, keeping pressure on borrowers and policymakers alike.
