Common Questions
What is the Persian Gulf Strait Authority and why did Iran create it?
Iran created the Persian Gulf Strait Authority on 5 May 2026 to require all vessels transiting the Strait of Hormuz to register, submit documentation, and pay a transit toll. It is a domestic-law instrument asserting Iranian sovereignty over the strait, directly challenging international maritime law under UNCLOS Article 38.Source: Maritime Executive
How does the Persian Gulf Strait Authority conflict with UNCLOS?
UNCLOS Article 38 guarantees ships of all flags the right of transit passage through international straits without prior authorisation. The Persian Gulf Strait Authority requires exactly that: registration, documentation, and a paid toll before clearance is granted. Iran withdrew from UNCLOS in 2007, giving it a contested argument the convention does not bind it.Source: Maritime Executive
Can ships pay Iran's Hormuz toll without violating US sanctions?
No. OFAC General Licence W names Iranian Red Crescent, Bonyad Mostazafan and Iranian embassy accounts as toll-payment channels that trigger US secondary sanctions exposure. A vessel that pays the toll faces OFAC action; one that refuses faces declared Iranian military intervention.Source: OFAC / Maritime Executive
What does MARAD Advisory 2026-004 say about the new Iranian Hormuz permit regime?
MARAD issued Advisory 2026-004 acknowledging the Persian Gulf Strait Authority alongside the pre-existing 2026-001 advisory on Iranian seizures. It is the first written US-government recognition that Iran has produced an institution Washington's own posture cannot reconcile with.Source: MARAD

Will the Persian Gulf Strait Authority survive a ceasefire or US pause of Project Freedom?
The authority is a domestic Iranian law instrument, not a kinetic deployment. It creates an institutional fact on paper that will outlast any pause, Ceasefire or resumption of escort operations. Even if Project Freedom is suspended indefinitely, the authority remains valid under Iranian domestic law.Source: Lowdown briefing
What is the Persian Gulf Strait Authority?
The PGSA is an Iranian body created on 5 May 2026 to collect tolls and issue transit permits for the Strait of Hormuz, operating under a Majlis sovereignty law that contradicts UNCLOS transit-passage rights.Source: event
How much does it cost to transit the Strait of Hormuz now?
Lloyd's List confirmed vessels are paying up to $2 million per ship to the PGSA for transit clearance, payable in Chinese yuan.Source: Lloyd's List
Why are Hormuz tolls being paid in Chinese yuan?
Paying in yuan bypasses US dollar correspondent banking, removing OFAC's primary enforcement mechanism against sanctioned transactions.Source: event
Is paying Iran's Hormuz toll legal for foreign ships?
No, OFAC's General Licence W makes dollar payments to PGSA a sanctions violation; but refusing to pay risks Iranian military intervention, leaving non-US vessels in a legal bind.Source: OFAC / MARAD

Background

The Persian Gulf Strait Authority (PGSA) is an Iranian state body established on 5 May 2026, one day after USS Truxtun and USS Mason made the first armed escort transit of the Strait of Hormuz under sustained IRGC fire. It requires vessels to register, submit formal documentation, and pay a transit toll before receiving clearance to enter a designated corridor through the strait. Deviation from the corridor, the authority states, triggers military intervention. The naming is deliberate: by calling itself a 'Persian Gulf' rather than 'Strait of Hormuz' body, Iran rejects the international-waterway designation that UNCLOS Article 38 attaches to the strait, which guarantees transit passage without prior authorisation for ships of all flags.

The authority creates a legal bind for non-US-flagged vessels: paying the Iranian toll triggers OFAC General Licence W secondary sanctions, while refusing to pay risks declared Iranian military intervention. The US Maritime Administration issued Advisory 2026-004 acknowledging the new transit regime alongside the pre-existing 2026-001 advisory on Iranian seizures, the first written US-government recognition that Iran has produced an institution Washington's own posture cannot reconcile with.

Lloyd's List confirmed on 7 May 2026 that vessels were paying up to $2 million per ship in Chinese yuan to obtain PGSA transit clearance, routing toll payments outside the US dollar correspondent-banking system . The yuan denomination is structurally significant: it removes OFAC's principal enforcement lever, since US dollar correspondent banking is the mechanism through which Treasury blocks sanctioned payments. European P&I clubs have not yet modified their war-risk cover suspensions to account for the new variable.

The PGSA rests on the legal foundation of the 2 May Majlis Hormuz sovereignty law, which Iran's Parliament ratified to underpin the toll and corridor regime . The authority is the structural Iranian advance of the May 2026 period: a domestic-law instrument that will outlast any pause, Ceasefire or resumption of US escort operations, because it creates an institutional fact on paper rather than a kinetic one on the water.
