Crude prices whipsawed on Thursday after President Donald Trump vowed new strikes on Iran and proclaimed that America would seize Kharg Island, the heart of Iran’s oil export network. Brent futures briefly traded at $93.72 a barrel, extending earlier gains, while West Texas Intermediate also advanced. The immediate trigger was a dramatic escalation in the war of words: Trump warned of attacks “tonight” and Iran retaliated by declaring the closure of the Strait of Hormuz, through which roughly a fifth of the world’s seaborne crude passes.

Viewed from Washington, the combative pledge to take control of foreign energy assets marks a belligerent turn in the stand-off, prompting alarm among diplomats and commodity strategists alike. In Tehran, officials framed the Hormuz declaration as a defensive necessity, though analysts in London observe that similar threats have rarely been executed and naval traffic was still moving on Thursday. From trading floors in New York and Singapore, the market’s focus was narrowly fixed on whether the military exchanges would translate into an actual supply outage; so far, tankers continued to transit the strait, and the early price spike deflated as scepticism set in.

The oil market’s seesaw reflected a balancing act between geopolitical alarm and underlying fundamentals. Beyond the headlines, investors were also scrutinising the latest OPEC monthly report, which offered a sobering background of ample supply and uncertain demand growth. Equity markets mirrored the skittish mood: a cautious bounce on Wall Street faded after Trump’s fresh threats, with the S&P 500 struggling to retain early gains. The pattern underscored how the Iran confrontation now dominates sentiment, yet without a concrete disruption, risk premiums remain brittle.

Looking forward, the trajectory of crude prices hinges on whether the rhetorical brinkmanship escalates into a genuine choke on exports. Should Iran follow through on a Hormuz closure, or should US forces interdict operations at Kharg, the supply shock would be severe and prices could leap by double-digit percentages. For the moment, however, the market treats such scenarios as tail risks. As one veteran analyst noted, traders have learnt to price in threats but only respond forcefully to facts. The coming hours will test whether this crisis signals a real rupture in Middle Eastern energy flows or merely another chapter of coercive diplomacy.
