U.S. Treasury yields moved higher on Friday after the Trump administration signaled its naval blockade of Iranian ports could continue “indefinitely,” adding to concerns over geopolitical tensions that have kept a bid under haven assets while pressuring the long end of the curve.
The yield on the 10-year Treasury note — the benchmark for U.S. government borrowing — rose 2 basis points to 4.661%. The 2-year note yield, which tracks short-term Federal Reserve policy expectations, climbed more than 1 basis point to 4.152%, while the 30-year bond yield added over 2 basis points to 5.237%. One basis point equals 0.01%, and yields move inversely to prices.
Sanctions rhetoric escalates
Friday’s moves came after Treasury Secretary Scott Bessent, in an interview with Newsmax, warned of fresh measures aimed at the “economic isolation” of Iran that “have never been seen.” His comments followed remarks from Defense Secretary Pete Hegseth, who told reporters U.S. forces could maintain an indefinite blockade of Iranian ports.
The escalation in rhetoric kept a geopolitical premium in play for risk assets, even as traders digested a fresh round of inflation data that suggested price pressures are cooling.
Inflation data offers some relief
The producer price index, which measures what wholesalers pay for raw goods and materials, was flat month over month in July, coming in below the 0.2% increase economists polled by Dow Jones had expected. That followed Thursday’s consumer price index report, which matched economist forecasts and pointed to contained price growth.
“US inflation data this week has been contained and very welcome for Treasuries,” ING strategists wrote in a note Friday. “It absolutely eases higher rates pressure. But that pressure is far from gone. Real yields are higher and will likely remain so.”
Despite the soft PPI reading, yields finished the session higher, suggesting investors remain focused on the Federal Reserve’s next policy moves and the potential for prolonged fiscal and geopolitical uncertainty.
Traders will now look ahead to next week’s commentary from Fed officials and any further developments on the Iran front for direction in the Treasury market.
