Iran Launches Official ‘Persian Gulf Strait Authority’ Account, Declares Unauthorized Hormuz Transit ‘Illegal’

The Iranian-backed Persian Gulf Strait Authority (PGSA) has officially launched a public presence on X, signaling a significant escalation in regional maritime security control. By declaring unauthorized transit through the Strait of Hormuz illegal, Tehran is attempting to formalize its jurisdiction over this critical chokepoint. This development directly impacts commercial shipping routes near Bandar Abbas and the Persian Gulf, forcing vessel operators to navigate an increasingly complex geopolitical landscape while monitoring potential interference with international freedom of navigation protocols.

From a regulatory perspective, this unilateral declaration challenges the established framework of the United Nations Convention on the Law of the Sea (UNCLOS), specifically regarding transit passage rights. Compliance departments must now reconcile these regional demands with existing IMO conventions, including SOLAS Chapter V on safety of navigation and the ISPS Code requirements for vessel security. Failure to adhere to these emerging local mandates could trigger detentions or security incidents, complicating insurance coverage and classification society audits for tankers and bulk carriers operating within these high-risk zones.

Masters and navigating officers must exercise heightened vigilance when transiting the Strait of Hormuz. These rank groups are now tasked with updating voyage risk assessments and maintaining constant communication with company security officers to verify the latest transit requirements. It is essential to monitor official maritime safety information broadcasts and ensure that all bridge teams are briefed on potential boarding protocols or reporting procedures mandated by the PGSA to avoid unnecessary operational delays or security confrontations.
