Iran has established the Persian Gulf Strait Authority to vet, tax, and control all vessel passages through the Strait of Hormuz [1, 2].
This move tightens control over one of the world's most critical maritime chokepoints, where the Persian Gulf meets the Gulf of Oman. Because the waterway is essential for global energy shipments, any restriction on navigation risks disrupting international trade and increasing shipping costs.
The new government agency implements a “pay-to-pass” protocol, requiring vessels to pay a fee for passage through the strait [3]. Under these tightened navigation rules, the authority is tasked with approving and taxing ships before they can proceed [2, 4].
Iranian officials said the measures are intended to safeguard national sovereignty and generate revenue [2, 3]. The government also said it needed to respond to heightened tensions with the U.S. regarding regional security and sanctions [2, 3].
Reports regarding the enforcement of these rules are conflicting. One report said that Iran fired on a tanker that attempted to transit the waterway without complying with the new protocols [5]. However, other reports focused on the resulting shipping logjam and did not mention any vessel being shot at [6].
The Persian Gulf Strait Authority now maintains a vetting process for all ships, effectively ending the previous status of unrestricted transit for commercial vessels [1, 4].
“Iran established a new government agency to vet, tax, and control all vessel passages through the Strait of Hormuz.”
The creation of the Persian Gulf Strait Authority signals a shift from sporadic interference to a formalized, institutionalized system of maritime control. By implementing a fee-based transit model, Iran is leveraging its geographic position to create a new revenue stream and exert political leverage over the U.S. and its allies. The discrepancy in reports regarding military action against tankers suggests a volatile environment where the threshold for escalation remains low.
