Bond Traders Suddenly See a Fed Hike on the Table as the Iran War Pushes Yields Higher

Bloomberg and the Wall Street Journal contributed to this report.

Treasury traders went into Friday thinking about one thing: inflation. Then they spent the day reacting to something bigger — the war in the Middle East, the jump in oil, and the growing sense that the Federal Reserve’s next move might not be a cut after all. US Treasuries sold off hard, yields rose by roughly 12 to 15 basis points across maturities, and bond markets started pricing in about a 50% chance of a Fed hike by October. That is a sharp reversal from before the US attacked Iran on Feb. 28, when money markets had fully priced in two quarter-point cuts this year.

The trigger was not subtle. Traders were already nervous about sticky inflation, then the Wall Street Journal reported that the US was sending three warships and more Marines to the region. That kept the pressure on yields and reinforced the idea that a prolonged conflict could keep energy prices elevated long enough to force central banks into a tighter stance. By Friday, the 10-year Treasury yield was hovering around the mid-4.3% range, with long-dated bonds also selling off.

The market’s mood has flipped fast. Just days ago, the story was rate cuts; now, some traders are talking about hikes. Bloomberg reported that the bond market’s big 2026 Fed bet has been turned upside down by the oil surge, while Reuters said the US dollar’s rally has stalled as investors reprice hawkish central-bank risk around the world. The message from bond desks is blunt: if the war keeps oil and shipping costs high, inflation may stay too hot for the Fed to relax.

It is not just a US story either. European and UK yields have jumped too, with market watchers warning that the energy shock could force the ECB and Bank of England to consider hikes sooner than expected. That matters because it shows how quickly a war-driven oil shock can spread from commodities to global rates, and then into mortgages, borrowing costs, and equity valuations. Markets are basically pricing a world where the old “cuts are coming” script has been replaced by “maybe rates stay high, or go higher.”

For now, investors are stuck waiting on the weekend and on the war itself. If the conflict eases, some of these rate-hike bets could unwind just as quickly as they appeared. If it drags on, the bond market is telling us it expects more inflation pain, more selling in Treasuries, and a Fed that may have to lean the other way. That is a very different market than the one traders thought they were in two weeks ago.
