Iranian parliamentary committees have advanced legislation since August 2026 authorizing service fees for navigation, security, insurance, and environmental measures in the Strait of Hormuz, following the expiration of a 60-day toll-free period under the June 2026 U.S.-Iran memorandum of understanding. Ad-hoc payments of up to $2 million per transit have been reported through IRGC-linked intermediaries, with priority passage granted to vessels from certain nations, while Iran coordinates with Oman on potential shared revenue mechanisms and a new maritime authority. U.S. officials continue to reject formal tolls on the international waterway, and the IMO maintains there is no legal basis for such charges under conventions governing straits used for international navigation. These steps, alongside ongoing post-conflict talks and draft bills finalized in recent weeks, shape trader assessments of when any mandatory, officially enforced fee system will take effect by specific deadlines.
