Treasury Yield Curve Steepens as Traders Avoid Long-Term Debt

Long-maturity Treasury yields reached the highest levels in a month Thursday as investors demand compensation for the risk that tariffs will spur US inflation.

Though the increases were pared in New York trading after US economic data provided no fresh catalyst for higher yields, the Trump administration’s late-Wednesday announcement of a 25% tariff on foreign-made cars next month saw the 30-year Treasury yield reach 4.75%, the highest level since Feb. 20.

Treasury Curve

The 30-year exceeded the five-year Treasury yield by more than 63 basis points, the widest gap since early 2022. The spread continued to widen as five-year yields led the retreat, aided by block trades in futures. Shorter-maturity Treasury yields have been curbed by the prospect of Federal Reserve interest-rate cuts later this year in response to signs of slowing US economic growth. Investors increasingly favor the five-year to capture the benefit of Fed rate cuts.

“The tariffs are weighing on the bond market,” said Tom di Galoma, a managing director at Mischler Financial Group. “The supply this week is a also a factor, as well as the coming month- and quarter-end, with some shift during this period back into equities. All of this is affecting bonds.”

An auction of seven-year Treasury notes Thursday drew a yield slightly higher than indicated in trading just before the bidding deadline, a sign that demand fell short of expectations.
