USOIL War Premium Cracks as Trump Signals Iran Ceasefire
Oil's war premium is cracking. The USOIL perp reversed 14.72% in under 24 hours after Trump signaled the Iran conflict could end soon, unwinding much of the historic run driven by the Strait of Hormuz closure. USO swung from an intraday peak near $124 back to $104, testing whether the market overpriced a prolonged supply disruption.
Mover Brief
The Reversal
USO swung from an intraday high of $124.07 to $104.33 on Monday, erasing most of the war premium that had accumulated over the previous week. WTI crude dropped 9.36% to $85.90; Brent fell 9.75% to $89.31.
The trigger: Trump told CBS News the Iran conflict was "very complete, pretty much" and would end "very soon," though he clarified it wouldn't wrap up within the coming week. Putin also presented peace proposals during a phone call with Trump. The market, which had just priced in a prolonged Hormuz disruption, immediately began repricing ceasefire probabilities.
What Built the Premium
The run that's now unwinding was historic. WTI posted its largest weekly gain ever — 35.6% — after US-Israeli strikes on Iran on February 28 killed supreme leader Ali Khamenei. The IRGC declared the Strait of Hormuz closed, tanker traffic dropped to effectively zero, and 20% of global daily oil supply was suddenly at risk.
The physical toll compounded fast. Iraq cut southern oilfield output by 70% to 1.3 million barrels per day, Kuwait declared force majeure, and Saudi Arabia reduced production. By March 8–9, oil had cleared $100 for the first time since Russia's 2022 Ukraine invasion, with WTI briefly touching $120.
Ceasefire Odds vs. Supply Reality
The selloff is pricing in a faster resolution, but the physical supply picture hasn't changed yet. The Strait of Hormuz remains effectively closed — Iran's latest position bars ships linked to the US, Israel, and Western allies. Iraqi and Kuwaiti production cuts are still in effect.
OPEC+ agreed on March 1 to a modest 206,000 b/d increase for April, but that barely dents the gap left by Gulf disruptions. IG Markets' Tony Sycamore expects crude to trade in a wide $75–$105 range in the sessions ahead. The question is whether Trump's rhetoric translates into an actual ceasefire — or whether this is just a dip before the Hormuz premium reasserts itself.
