Iran has maintained de facto control over transit through the Strait of Hormuz amid a crisis that began in late February 2026, establishing the Persian Gulf Strait Authority in May to issue permits and collect service fees covering navigation, insurance, safety, and related support. Parliamentary committees advanced legislation in September authorizing charges for authorized vessels, while reports indicate ad-hoc payments reaching $2 million per ship have occurred on a selective basis. International bodies including the IMO have rejected any legal basis for tolls, and diplomatic efforts involving the US, Oman, Qatar, and others continue over corridors, permits, and postwar arrangements. Traffic remains severely restricted, with traders monitoring legislative progress, enforcement consistency, and negotiation outcomes through the resolution window.
