Iran’s establishment of the Persian Gulf Strait Authority in May 2026 and parliamentary approval of the Hormuz Transit Fee Law have created a legal and administrative framework for levying passage charges, with recent reports indicating the IRGC is already collecting informal fees—often around $1 per barrel for tankers or up to $2 million per transit—through intermediaries, prioritizing vessels from favored nations. Negotiations with Oman under the June 2026 U.S.-Iran memorandum continue to shape future administration and maritime services, while shipping groups and the United States emphasize freedom of navigation under international law. These developments, alongside post-conflict revenue needs and ongoing permit requirements, directly influence trader assessments of whether systematic charging will be formalized or sustained.
