Iran's IRGC Declares Mandatory Shipping Routes in Strait of Hormuz

Iran's Islamic Revolutionary Guard Corps Navy warned on 25 June 2026 that vessels outside Iranian-designated routes in the Strait of Hormuz face restricted access to the waterway carrying roughly 20% of global petroleum. The formal declaration converts sporadic threat into structured compliance demand, forcing shipowners to either follow Iranian corridors or absorb heightened physical and insurance risk.
