Iran Launches Hormuz Toll Agency, Charges $2M Per Ship

Iran has formally established the Persian Gulf Strait Authority, a new administrative body that will collect transit tolls of up to $2 million per commercial vessel passing through the Strait of Hormuz, according to reporting by Maritime Executive and CNN. The move transforms what had been ad hoc IRGC naval harassment into an institutionalized revenue mechanism — and instantly creates a compliance crisis for every shipping company, insurer, and charterer operating in the Persian Gulf.

The strait carries roughly 20 percent of global oil trade. As of Friday, Brent crude settled at $101.73 and WTI at $94.81, with the Energy Information Administration estimating 14 million barrels per day disrupted — the largest sustained supply shock since the 1970s. The PGSA announcement sent insurance underwriters scrambling to reprice war-risk coverage that had already doubled since March.

How the PGSA Works

Iranian authorities framed the Persian Gulf Strait Authority as a sovereignty exercise, asserting that the Strait of Hormuz falls within Iranian territorial waters and that transit fees are a lawful exercise of jurisdictional rights under international maritime frameworks. IRGC Navy units will serve as the enforcement arm — the same force that has seized four tankers since March and disabled two others.

Under the published fee schedule, tolls range from several hundred thousand dollars for smaller vessels to $2 million for very large crude carriers. Vessels are required to submit transit notices 48 hours in advance through a new online portal operated by the PGSA and to carry an Iranian-issued transit certificate aboard. Failure to comply, Iranian authorities stated, would result in boarding, inspection, and potential detention.

The IRGC Navy’s recent operational record gives the threat credibility. The M/T Ocean Koi, seized earlier this week, became the fourth tanker detained by Iranian forces since late March. U.S. naval assets disabled the tankers Sea Star III and Sevda in response to earlier Iranian seizures, a tit-for-tat exchange that has left multiple vessels stranded and their crews in legal limbo.

The Compliance Trap

Shipping operators now face mutually exclusive legal obligations. Paying the PGSA toll creates exposure under U.S. sanctions law. Refusing it risks vessel seizure by IRGC forces. There is no path through the strait that does not carry significant legal or physical risk.

The U.S. Treasury Department’s Office of Foreign Assets Control made that tension explicit Friday, announcing sanctions against 10 entities across China, the UAE, Belarus, and Europe in what officials called an “Economic Fury” campaign targeting Iranian UAV and missile procurement networks. The designees include Hitex Insulation Ningbo, accused of supplying carbon fiber composites to IRGC weapons programs; Hong Kong-based Mustad Limited, cited for facilitating IRGC financial transactions; and Belarus-based Armoury Alliance LLC.

Buried in the Treasury press release was explicit language threatening secondary sanctions against any entity — including foreign shipping companies, insurers, and financial institutions — that remits payment to Iran’s new Persian Gulf Strait Authority. OFAC characterized toll payments as material support to a Specially Designated Global Terrorist organization.

That language puts European and Asian carriers in direct conflict with their home regulators. Several EU member states have indicated they cannot instruct national companies to violate Iranian maritime law while simultaneously transiting waters Iran controls. Legal advisers contacted by shipping industry publications described the situation as “jurisdiction collision” with no clean resolution.

War-risk insurance, already strained by three months of tanker seizures and U.S. Navy engagements, is the pressure point most likely to break first. Lloyd’s of London syndicates have informally suspended new coverage for Hormuz transits pending legal analysis of the PGSA toll structure and OFAC’s secondary sanctions threat. Without insurance, most major charterers cannot legally move cargo — rendering the strait economically closed even if it remains physically navigable.

Economic Fury Meets Diplomatic Deadlock

The OFAC designations and the PGSA announcement landed against a backdrop of failed diplomacy. Secretary of State Rubio’s 14-point memorandum of understanding, delivered to Iranian authorities last week, carried a response deadline that passed without a formal reply. Iran’s parliament publicly dismissed the document as “Operation Trust Me Bro,” with lawmakers arguing the MOU contained no sanctions relief timetable and no security guarantees.

The Project Freedom naval escort mission, which had been providing U.S. warship accompaniment to non-Iranian commercial vessels, was paused May 6 amid diplomatic signals suggesting talks were still possible. That pause now looks premature. With the PGSA operational and OFAC sanctions expanded, the conditions that justified the pause no longer appear to hold.

The physical-to-futures oil price spread has widened further since the PGSA announcement, as spot buyers in Asia price in the toll cost and insurers add surcharges. Analysts at two major commodity trading houses told industry publications Friday that the effective cost of a Hormuz transit — toll, insurance surcharge, and legal indemnification — could exceed $4 million per VLCC voyage, making alternative routes economically attractive for the first time in years.

Suez Canal traffic is already up sharply, and the Cape of Good Hope route, adding 10–14 days to Asia-bound voyages, is being rebooked at rates that would have been unthinkable in January. Neither alternative clears the bottleneck; both push delivered energy costs higher into an already strained global economy.

What Comes Next

Three variables will determine how this resolves.

First, whether any major shipping company tests the PGSA compliance framework — either by paying the toll and accepting OFAC exposure, or by refusing and losing a vessel. The first test case will clarify how seriously Iranian authorities intend to enforce collections and how aggressively OFAC pursues secondary sanctions.

Second, whether Project Freedom resumes. U.S. naval escorts had provided practical deterrence against IRGC boarding actions. Their absence since May 6 is the operational window in which the PGSA launched. A Project Freedom restart, combined with the tanker seizure and disablement pattern already established, would test whether Iran enforces tolls against escorted convoys.

Third, whether the MOU process revives. The Rubio deadline passed without a formal response, but Iranian officials have not publicly closed the channel. A backchannel communication — or a formal counterproposal — would likely prompt another Project Freedom pause and could delay PGSA enforcement pending the outcome of talks.

The satellite imagery of the Kharg Island oil slick released earlier this week suggests Iranian export infrastructure has taken damage that Iranian authorities have not publicly acknowledged, adding a domestic economic pressure that may or may not influence decision-making in Tehran.

For shipping operators, insurers, and energy traders, none of those variables resolve the immediate problem: a vessel approaching Hormuz today faces legal exposure regardless of the choice it makes. That is not an accident. It is the architecture of the crisis.
