Brent climbed toward $113 a barrel, while West Texas Intermediate briefly topped $100. Trump said Iran must “fully open,” the waterway within 48 hours, or have its power plants bombed. In reply, Tehran warned it will target “all energy, information technology, and desalination infrastructure belonging to the US and the Israeli regime in the region” if fuel and energy sites were hit.

Global benchmark Brent has surged by more than 50% since the strikes by the US and Israel on Iran in late February.

And Iran is clearly able and willing to match any escalation.”

With maritime traffic through Hormuz at a standstill — apart from a handful of transits agreed to by Tehran — Persian Gulf crude producers have been forced to lock in millions of barrels of daily supply, or turn to limited, alternative export routes. The International Energy Agency has warned the global oil market is facing its largest-ever shock, even as it presided over a major release of emergency stockpiles from member nations.

Part of the growing challenge for investors — beyond fatigue and extraordinary levels of volatility — has been Trump’s lack of coherent messaging on the conflict. Shortly before his two-day ultimatum, the president had said he was considering “winding down” US military efforts against Iran.

“Feels like we’ve shifted from reacting to headlines to waiting for confirmation, so the next real move needs something tangible, and not just escalation rhetoric,” said Haris Khurshid, chief investment officer at Karobaar Capital LP in Chicago. “It will probably take more broader issues with shipping or insurance before prices start moving more aggressively,” he added
