The Strait of Hormuz has lurched into open crisis as Iran’s Islamic Revolutionary Guard Corps (IRGC) announces it has “taken control” of the chokepoint, warning U.S.‑linked tankers they now sail “under the shadow of our missiles,” even as Donald Trump orders American warships to escort them through.

Fast‑attack boats flying IRGC flags have been filmed swarming around crude carriers near the narrowest stretch of the strait, while drones and coastal missile batteries track every move from the cliffs above. At least one US‑chartered tanker reported warning sH๏τs landing within metres of its bow after refusing an IRGC demand to divert into Iranian waters for “inspection.”

From Washington, Trump has authorised an emergency convoy operation: destroyers, cruisers and minesweepers forming steel corridors around outbound tankers, helicopters overhead and electronic‑warfare aircraft jamming Iranian radars. “Any missile fired at our ships or our tankers,” he declared from the White House lawn, “will be treated as an attack on the United States itself.”

Oil markets reacted instantly. Prices spiked, war‑risk insurance doubled overnight, and several European and Asian shippers ordered vessels to hold position outside the Gulf rather than run the gauntlet between IRGC boats and US escorts.

Tehran insists it is merely enforcing “security and sovereignty” after weeks of US–Israeli strikes on Iranian ᴀssets. But for crews staring at armed speedboats through binoculars—and for a world that gets a fifth of its oil through this narrow waterway—the reality is starker: the Strait of Hormuz is no longer just a shipping lane, but the front line of a showdown where one misread signal could set the global economy on fire.
