Iran Denies Trump's Deal Claims as Oil Swings 14% — Hormuz Still Shut
Brent front-month futures last closed at $100.17 and WTI at $88.45 per Yahoo Finance as of 23 March 2026 14:18 UTC, with both benchmarks posting steep session losses after President Trump announced "very good and productive conversations" with Iran and ordered a five-day postponement of military strikes against Iranian energy infrastructure. Brent whipsawed from an intraday high above $113 to a session low of $96 before partially recovering, while WTI briefly touched $84 before rebounding — a range that reflects the full weight of the diplomatic uncertainty per Detroit News as of 23 March 14:01 UTC.
Iran's foreign ministry and state-affiliated media explicitly disputed Trump's claim that talks had taken place, with the Iranian Revolutionary Guard Corps warning that the Strait of Hormuz "will be completely closed" should any strikes proceed per CNN as of 23 March 10:16 UTC. The denial drove a partial price recovery off session lows, signalling that markets are treating the diplomatic narrative as unconfirmed. The Strait remains effectively closed, with Goldman Sachs estimating flows at only 5% of normal levels per CNBC as of 23 March 06:07 UTC.
Two additional supply-side developments are intensifying the pressure. Saudi Arabia has slashed crude exports to Asia from 7.1 million barrels per day in February to approximately 4.355 million barrels per day in March due to Strait constraints, with Aramco attempting to reroute flows through Yanbu on the Red Sea per OilPrice.com as of 23 March 11:30 UTC. Separately, Ukraine struck Russia's Primorsk oil export terminal — one of Russia's largest, handling approximately one million barrels per day — igniting fires at at least four storage tanks per New York Post as of 23 March 13:56 UTC, adding a second concurrent supply disruption to an already severely stressed global market.
Trump's five-day strike pause did real work in deflating the immediate war premium — the swing from $113 to sub-$88 intraday illustrates exactly how much escalation risk had been baked into prices. But the structural supply deficit is entirely unchanged: the Strait of Hormuz remains at just 5% of normal flows, Saudi export volumes to Asia have been cut by roughly 2.75 million barrels per day, and the IEA has characterised damage to over 40 regional energy assets as "severe or very severe" — meaning even a ceasefire would not restore supply quickly. Goldman Sachs has raised its Brent forecast to an average of $110 for March and April, and warned that if Hormuz flows remain at 5% through April 10, prices are likely to exceed the 2008 record of approximately $147 per barrel.
Iran's explicit denial of negotiations is the single most critical forward-looking variable: if the five-day window closes without verifiable diplomatic progress, the risk premium that was just ejected from prices has a clear and immediate catalyst to re-enter. The simultaneous strike on Primorsk introduces a second, non-Iran supply disruption that limits the downside for prices even in a genuine de-escalation scenario. Meanwhile, the US Treasury's one-month sanctions waiver allowing Chinese state refiners to purchase Iranian crude is unlikely to attract meaningfully new buyers, given that independent Chinese teapots were already purchasing sanctioned barrels at a discount — leaving the waiver's price-dampening effect in serious doubt.
