Iran's parliament is considering legislation that would bar vessels linked to the United States, Israel and other "hostile countries" from passing through the Strait of Hormuz until those countries compensate Iran for war damages. The move would also see other commercial shipping charged a toll of up to 7% of cargo value, with a 20% fine for vessels that breach Iran's conditions. The strait is one of the world's most important shipping corridors for crude oil, liquefied natural gas and other goods, so any restriction on transit risks pushing up global fuel and fertiliser prices and disrupting supply chains far beyond the region.

The proposal follows a war that began on 28 February 2026, during which the US imposed naval blockades on Iran in April and July; a temporary agreement reached in mid-June collapsed within weeks. A US official rejected Iran's toll plan, saying any temporary routes negotiated would carry "no approvals or permissions and no tolls or charges." Iran has separately finalised alternative shipping route agreements with Oman covering northern and southern corridors, while regional tensions have deepened further, with Pakistan, Saudi Arabia and Turkey signing a mutual defence pact and Iran-backed Houthi forces attacking Saudi Arabia, injuring 11 people.
