Iran is charging up to two million dollars per vessel to transit the Strait of Hormuz — an IRGC-controlled corridor between Larak and Qeshm islands where ships go dark on AIS tracking. The blockade didn't fail. It evolved. The military chokepoint became a fiscal chokepoint.
Iranian lawmaker Alaeddin Boroujerdi appeared on state television on March 22 and said what the market had not yet priced: "Collecting two million dollars as transit fees from some vessels crossing the strait reflects Iran's strength." He called it a new concept of sovereignty — the first Iran has asserted over Hormuz in forty-seven years, since the revolution.
The same day, Iran's parliament speaker denied that any negotiations with the United States had occurred. Two statements from the same government, on the same day, pointing in opposite directions — unless you read them together. The denial was not a rejection of diplomacy. It was a declaration that Iran does not need diplomacy. The strait is open. The toll is the price.
The Corridor
The mechanics are precise. Ships seeking transit submit ownership details, cargo manifests, and crew nationalities to the Islamic Revolutionary Guard Corps. The IRGC vets each vessel and, if approved, routes it through a controlled corridor between the islands of Larak and Qeshm — both in Iranian territorial waters. Upon entering the corridor, vessels go dark on AIS tracking systems. They reappear only after clearing the Gulf of Oman on the other side.
As of March 22, at least nine vessels had cleared the corridor. Two Indian-flagged LPG carriers. A Saudi oil tanker carrying one million barrels bound for India. A Pakistani government-owned aframax tanker. Six bulk carriers. A Turkish-owned vessel. Chinese-linked ships carrying agricultural products.
The filter is not by vessel type. It is by flag state and ownership. Ships linked to the United States or Israel are excluded. Everyone else submits to the vetting process and, reportedly, to the fee. Bloomberg reported that payments are sought on an ad hoc basis — the mechanism is not yet systematic, the currency not yet standardized. One tanker operator confirmed paying approximately two million dollars. Reports indicate payment is accepted in cash, cryptocurrency, or barter.
Meanwhile, the strait that normally handles hundreds of transits daily recorded sixteen AIS-visible crossings in the past seven days.
The Precedent
The last time a sovereign charged tolls on an international strait, enforced by the threat of cannon fire, was Denmark's Sound Dues. King Eric of Pomerania imposed the tax in 1429 on all foreign ships passing through the Øresund between Denmark and Sweden. Ships that refused to stop at Helsingør could be sunk from both shores. The toll began as a flat fee and evolved in 1567 into a one-to-two percent tax on cargo value, tripling revenue. At their peak, the Sound Dues constituted two-thirds of Denmark's state income. They lasted four hundred and twenty-eight years, abolished only in 1857 after international pressure and a compensation payment of thirty-three and a half million rix-dollars.
The parallels are structural, not decorative. A sovereign controlling a narrow waterway. A vetting process that determines who transits. Fees calibrated not to close the strait but to extract revenue from its continued operation. Military enforcement as the backstop. And the critical detail: the toll lasted centuries because it was more profitable to keep the strait barely open than to close it entirely.
Iran's parliament is reportedly drafting legislation to codify the fees permanently — transforming a wartime improvisation into a permanent fiscal instrument.
The Shift
Read the crisis chronology. On March 3, Iran closed the strait — coercion, pure denial. The Chokepoint. On March 5, insurance repricing made the closure effective even where the navy could not — the Embargo. On March 6, Trump demanded unconditional surrender — the Ultimatum. On March 15, Kuwait declared force majeure. On March 22, Iran began charging two million dollars per transit.
The progression is not escalation. It is optimization. Iran moved from denial of passage to extraction from passage. From coercion — do what we want or we close the strait — to taxation — the strait is open, and the price is two million dollars. The value proposition shifted from threat to service.
Countries are lining up. China, India, Pakistan, Iraq, and Malaysia are in direct talks with Tehran over access. Japan received a formal transit offer from Iran's Foreign Minister — the first major US ally to receive such an arrangement. France and Italy have requested talks. India's government objected publicly that international law guarantees freedom of navigation and no one can levy fees on the channel. Iran signed the United Nations Convention on the Law of the Sea. It did not ratify it.
The major container lines — Maersk, Hapag-Lloyd, CMA CGM — rerouted around Africa via the Cape of Good Hope, adding ten to fourteen days per voyage. The rerouting is expensive but avoids the toll. For oil tankers, the math is different. A two-million-dollar fee on a cargo worth a hundred million dollars is two percent — expensive but cheaper than the Cape detour for time-sensitive energy shipments.
Brent crude is trading above a hundred dollars a barrel, up forty-three percent in a month. The market dropped eleven percent on Trump's claim of productive conversations with Iran. It rebounded when Iran's parliament speaker called the claim fabricated news intended to manipulate financial and oil markets. The physical damage — two Qatari LNG mega-trains requiring three to five years and tens of billions to repair, Kuwait's refining infrastructure struck, sixteen transits per week where there were hundreds — does not respond to diplomatic rhetoric.
The toll is the signal that Iran is settling in. A blockade is temporary by nature — it costs the blocker as much as the blocked, and it invites military response. A toll is permanent. It generates revenue. It creates a constituency — every country negotiating access, every shipping company paying the fee, every intermediary facilitating the transaction — that benefits from the arrangement continuing. The sound dues lasted four hundred and twenty-eight years not because Denmark was powerful but because too many parties profited from the arrangement to challenge it.
Iran's denial of negotiations was not posturing. It was the operational signal. You do not need to negotiate when you are collecting two million dollars per ship.
