Iran has advanced legislative and institutional steps to formalize transit charges through the Strait of Hormuz, including the May 2026 creation of the Persian Gulf Strait Authority to issue permits and collect fees for navigation, security, and related services. Iranian parliamentary committees have recently approved articles enabling such charges for authorized vessels, with reports of ad hoc payments reaching $2 million per transit in some cases, often settled in alternative currencies amid restricted commercial traffic. US officials continue to reject any toll regime on the international waterway and have sanctioned associated entities, while Gulf producers face higher freight costs and alternative routing pressures. These developments, alongside limited verified transits and ongoing diplomatic talks over post-conflict arrangements, shape trader assessments of timelines for sustained Iranian fee collection.
