Iran Says Strait of Hormuz Blocked After Supertanker Hits Mine

The significance here is less the vessel loss than the claim of closure itself: the IRGC is asserting control over the world's most important oil chokepoint, which puts the burden on shippers, insurers and navies to either test or accept that claim. Anyone moving crude, LNG or dry bulk through Hormuz now faces a war-risk calculus that reprices by the hour. The open question is whether the Guards' declaration is matched by enforcement, and whether commercial traffic halts or reroutes on its own — that, not the statement, is what determines the real disruption.
