The 12-article statute behind the PGSA, ratified by Iran’s National Security and Foreign Policy Committee on 21 April, formalises the legal architecture: rial-denominated fees, Israeli vessels banned, hostile-flag SNSC approval, 20 per cent cargo confiscation for non-compliance. This post reads each substantive provision against the equivalent at the Suez Canal Authority and the Panama Canal Authority, and shows where the legal-architecture choice produces a sovereignty-asserting state-security instrument rather than a chokepoint authority.

On 18 May 2026, Iran formally announced the Persian Gulf Strait Authority, the institutional body administering its toll-booth corridor through the Strait of Hormuz. Tehran has built a chokepoint authority. It is not, on its present design, the configuration the operator class, the United States, China, the GCC, or the site has been arguing for. This post reads the PGSA in detail and identifies the six features that separate it from a treaty-backed authority on the Suez or Panama model.

On Persian Gulf Day, April 30, Iran’s Supreme Leader announced a new framework for managing the Strait of Hormuz: rial-denominated proceeds, surcharge for sanctions countries, the General Staff of the Armed Forces as administering body, and an invitation to GCC participation. Set side by side with treaty-backed practice at Suez and Panama, the framework is a unilateral authority claim that clarifies, rather than closes, the institutional gap.

The US Treasury has stated this week that payments to Iran or the IRGC for Hormuz passage, direct or indirect, are not authorised for US persons or US banks. Walked through at desk level for tanker owners, charterers, correspondent banks, and refiners, the rule closes the dollar payer set for the current toll arrangement. The four-leg architecture of the regime is now complete from the US compliance side.

Phemex analysis confirms the Strait of Hormuz is now a Bitcoin and stablecoin tollbooth. One dollar per barrel, up to 2 million per VLCC, settled in USDT on Tron and Bitcoin on Lightning. Public estimates run to 7.5 billion dollars a year at full scale. The infrastructure is operational. The question is not whether tolls can be collected. Iran has proven they can. The question is under what governance.

On Sunday 19 April, USS Spruance fired on and disabled the Iranian flagged cargo ship Touska in the Gulf of Oman. Marines boarded and took custody. First seizure of the crisis. Tehran has vowed retaliation. The line between blockade and seizure has been crossed, and it is structurally difficult to walk back.

Over the seven days ending 19 April, named vessels including Atokos, Serifos, Cospearl Lake, He Rong Hai, Rich Starry, Kashan, Rayan, Daisy, Golbon, G Summer, and Hong Lu completed IRGC cleared transits. Fees paid in yuan via CIPS, Bitcoin, and USDT. The Hormuz Tollbooth is scaling, not speculative.

On 19 April, a spokesperson for Iran’s Central Headquarters of the Holy Prophet announced the official operating rule for the Strait of Hormuz: vessels that pay faster get priority, vessels that do not are delayed. Iran has built, unilaterally and under international rejection, a working toll system. Every design choice is the inverse of what makes Suez and Panama legitimate.

The IRGC fired on a tanker and a projectile struck a container vessel in Hormuz today. Two of the ships are Indian flagged. India summoned Iran’s ambassador. CENTCOM has now turned back 23 vessels in the Gulf of Oman. A strait with a multilateral authority could have prevented all of this by design.

At 19:00 GMT on Friday, Iran’s foreign minister declared the strait ‘completely open’ for the ceasefire. By Saturday morning, the IRGC said control had returned to ‘its previous state.’ Brent crude traded 11.5 percent below Thursday in the interim. The whipsaw is exactly what an institutional authority is designed to prevent.
