Oil retreats as U.S.-Iran tensions ease, but supply risks linger

Oil markets pulled back on Thursday morning as traders tried to read the tea leaves of a fresh U.S.-Iran confrontation that had rattled the Middle East just hours before. Brent crude, the global benchmark, dropped 43 cents to settle at $95.20 a barrel, while West Texas Intermediate—the U.S. standard—fell 24 cents to $90.77. The moves were modest, but they reflected something more interesting than simple price discovery: investors were watching to see whether the latest military exchange would actually hold or whether the region was about to slip back into open conflict.

The fighting itself had been substantial. The U.S. campaign against Iran represented the most serious exchange of fire between the two countries since July, now seven months into what had become an escalating cycle. President Trump confirmed on Wednesday that American forces had struck Iranian radar and missile systems, including new equipment Iran had positioned along the Strait of Hormuz—some defensive, some built for offense. "It was a very heavy attack last night, and we're prepared to do another one any time we want," Trump said, a statement that left little ambiguity about U.S. readiness to continue. Yet he also offered a signal that might have eased some market anxiety: the campaign would not drag on for "too long."

What mattered most to oil traders was not the rhetoric but the silence that followed. By midday Wednesday Sydney time, no new confirmed fire had been reported. That pause—tentative as it was—seemed to be what pulled prices down. Analyst Tony Sycamore at IG noted the retreat in a straightforward way: if the easing held, and he was careful to emphasize that it was a significant if, then the tanker traffic that had been disrupted would likely resume. The Strait of Hormuz, one of the world's most critical chokepoints for crude, had become a flashpoint for both military action and commercial uncertainty.

The numbers told the story of disruption. On Wednesday, only four commodity vessels transited the strait, well below the ten-day average of around thirteen. That gap mattered because the strait handles roughly one-third of all seaborne traded oil globally. The U.S. reported that 17 million barrels had moved through on Monday—the largest volume since the conflict began—but that figure seemed to be an outlier, a moment when traffic had surged before the latest strikes. Iran, meanwhile, had added more vessels to its list of ships deemed non-compliant, meaning they faced potential fines, confiscation, or detention if they attempted passage. It was a form of pressure that operated in parallel to the military dimension.

During the previous trading session, both Brent and WTI had swung wildly, gaining as much as two dollars a barrel at their highs before losing a dollar at their lows. The session highs for both benchmarks were the strongest since July 24, a sign that traders had been pricing in genuine supply disruption risk. But the pullback on Thursday suggested that the market was willing to give the de-escalation scenario a chance—at least for now. The real test would come in the hours and days ahead. If the quiet held and tankers began moving through the strait again, oil could stabilize. If the fighting resumed, prices would likely spike once more, and the fragile equilibrium that had emerged would shatter.
