Treasury yields fall as Iran deal cuts Fed hike odds

The two-year Treasury yield dropped five basis points to 4.03 per cent on Monday after a US-Iran framework agreement pulled oil-shock fear out of the market and sent traders back into government bonds.

Buying spread across the curve, with the benchmark 10-year yield down five basis points at 4.43 per cent. Swaps traders put the chance of a quarter-point Federal Reserve hike by December at about 60 per cent, down from about 80 per cent on Friday, Bloomberg reported. For a market that had spent days trading the war through crude, the first clear response was in rates.

The front end had the most to unwind. Traders had been paying for protection against the risk that higher energy prices would feed into the inflation data facing Fed Chair Kevin Warsh. Once crude broke lower, two-year notes had room to rally because they sit closest to expected Fed policy.

Brent crude fell 4 per cent after the deal news, easing the inflation premium that had built while markets watched the Strait of Hormuz. The CNBC cross-asset snapshot also showed the US dollar index down 0.32 per cent to 99.483, a weaker-dollar move that put the de-escalation trade into currencies as well as bonds.

Matthew Haupt, a hedge fund manager at Wilson Asset Management, said the Treasury reaction reflected a positioning clean-out after investors had sold rates during the conflict. “Some of the short positioning in rates will be taken off,” Haupt said.

The policy channel is narrow but important. Lower oil prices reduce the chance that energy costs pass into consumer prices, which gives Warsh and other Fed officials more room to wait before tightening again. Bond traders had been carrying the risk that a Middle East supply shock would force the central bank to lean harder against inflation. Monday’s rally suggested that risk was no longer the base case.

What changed in rates

Billy Leung, investment strategist at Global X ETFs, told CNBC the move was about the inflation risk premium built since the Strait closed. “The most immediate implication is a repricing of the inflation risk premium that markets have been carrying since the Strait closed,” Leung said.

That repricing sits at the centre of the Fed trade, even if the yield move was not large by historical standards. A five-basis-point drop in the two-year yield matters because the front end is where rate-hike expectations show up most directly. It showed traders were less willing to pay for protection against another Warsh-led tightening step in the second half of 2026, and more willing to treat the oil shock as a tail risk rather than the main path for inflation.

The deal is not final.

The Financial Times said the framework would extend the ceasefire by 60 days, reopen the Strait of Hormuz and start a new round of nuclear negotiations. CNBC said investors were still treating the announcement cautiously because Washington and Tehran had not signed the agreement and continued to differ on details.

That leaves the relief trade exposed to implementation risk. Andrew Ticehurst, cited by Bloomberg, warned that markets could face a nervous interval before the Strait reopens on Friday. Tanker flows resuming on schedule would help the bond rally lean on lower inflation expectations. A delay would give the Treasury shorts covered on Monday a reason to rebuild quickly.

For now, the bond market has shifted the debate away from oil-shock inflation and back toward whether the Fed already has rates high enough. Monday’s yield move showed traders less convinced that another hike is coming, but the trade still depends on a geopolitical timetable rather than only on the next inflation print.
