Iran's Strait of Hormuz Toll Regime Is Extortion, Not a Trade Dispute

Roughly 500 merchant ships are riding at anchor in the Persian Gulf because the most important energy chokepoint on Earth now functions as a toll plaza administered at missile point. The United Nations puts the number of seafarers trapped aboard those vessels at about 6,000. Fifty people have been killed and more than 500 injured since hostilities between the United States and Iran resumed in mid-July, according to figures the UN released last week. Secretary-General Antonio Guterres called the situation one "teetering on the edge of the unimaginable." He is right, and the more uncomfortable truth is that governments and much of the shipping industry have started to process the unimaginable as a line item.

The Strait of Hormuz normally handles about 135 transits a day and carries around a fifth of the world's oil and gas, according to the UN's maritime agency. That flow has been throttled since late February, when the United States and Israel opened an air campaign against Iran and Tehran answered by turning the waterway itself into its principal weapon. The question before the world's trading nations is no longer whether the strait can be forced open by episodic airstrikes; five months of evidence says it cannot. The question is whether maritime powers will build the collective escort, insurance and diplomatic architecture that treats free transit as a public good, or whether they will quietly accustom themselves to paying rent at Hormuz.

Truce built on sand

The memorandum of understanding signed on June 17 by President Donald Trump and Iranian President Masoud Pezeshkian was supposed to end the war and the blockade together. It did neither, because it left intact the machinery Iran had constructed to control the strait. In May, Tehran established what it calls the Persian Gulf Strait Authority, a body that licenses transit for vessels flagged to governments it considers friendly, among them China, Russia, India and Pakistan, while excluding American, Israeli and allied shipping, according to the documented record of the crisis. Within days of the June signing, Iran declared the strait closed again, citing Israeli violations, and by July 8 the interim truce had collapsed after fresh strikes on commercial vessels.

CNN reported on July 11 that American forces had hit roughly 140 Iranian military targets in the third round of strikes that week, after the Islamic Revolutionary Guard Corps attacked a Cyprus-flagged container ship whose operator reported one crew member missing. The IRGC's own account, that it fired a warning shot at a vessel using an unauthorized route, is in its way the most revealing document of the entire crisis. Tehran does not deny controlling access; it advertises the fact. A route becomes unauthorized only if you claim the authority to authorize it.

This is why the June memorandum failed, and why any successor drafted on the same template will fail. A ceasefire that leaves a coercive licensing regime standing over an international waterway is not a peace. It is a fee schedule with a grace period.

Extortion, repriced as a surcharge

Markets have responded the way markets do: by pricing the outrage rather than resisting it. Brent crude pushed past $100 a barrel in March for the first time in four years and peaked near $126, according to accounts of the crisis compiled from market data. When the June memorandum briefly held, CNBC reported in late June that prices had eased back toward pre-war levels near $70 a barrel, even as analysts warned that traders were underestimating lingering shipping risk and the demand needed to rebuild depleted inventories. The July resumption of hostilities vindicated that warning.

The adjustment is visible everywhere in the freight economy. War-risk insurance premiums reportedly climbed from about 0.125 percent of hull value before the war to as much as 0.4 percent, an increment worth roughly a quarter of a million dollars on a single transit by a large tanker. Hapag-Lloyd, the world's fifth-largest container line, told Gulf News that it is "refraining from transiting the strait" until Iranian authorities provide explicit written safety guarantees and clear guidance on permitted routes. Allianz Economic Research estimates that traffic could need six months or more to recover to pre-war levels even after a durable reopening, Gulf News reported.

Each of these adaptations is individually rational and collectively corrosive. Every surcharge, every rerouting, every premium paid is a data point proving to Tehran that the model works: a state can convert geography into revenue and leverage, and the global economy will absorb the cost rather than organize against it. Chokepoint extortion, once demonstrated as viable at Hormuz, will not stay at Hormuz. The Red Sea campaign waged by the Houthis from 2024 taught that lesson once already; the strait is now teaching it at far greater scale.

Six thousand people, five hundred ships

Beneath the macroeconomics sits a humanitarian scandal that deserves more prominence than it has received. The seafarers stranded in the Gulf are civilians, drawn overwhelmingly from developing countries, and they are being killed in a war they have no part in. The head of the International Maritime Organization, Arsenio Dominguez, has pointed out that crews are not trained for combat, that merchant vessels have no defense against missiles and drones, and that about 90 percent of traded goods move by sea, according to UN News. The UN has demanded the immediate evacuation of trapped crews, regional de-mining before shipping resumes, and an end to toll charges it describes as a violation of international law.

That last point matters. The UN system, not given to bold legal pronouncements about member states, has stated plainly that charging for passage through Hormuz is unlawful. The law of the sea guarantees transit passage through straits used for international navigation. But a legal norm that is asserted and never enforced decays into a suggestion.

Escort duty is a collective obligation

Enforcement, however, should not be confused with more airstrikes. The IMO's secretary-general cautioned as early as March, in remarks reported by S&P Global, that naval escorts alone would not ensure safe transits, and the American experience since then has proven the point in the negative: roughly 140 targets struck in a single week, and the strait remained shut. Military pressure without an institutional framework produces exactly what the world now has, a cycle of attack and reprisal with the global economy as collateral.

The workable alternative has three parts. First, a genuinely multinational convoy and mine-clearance operation, assembled under the broadest possible coalition and coordinated with the IMO, so that an attack on a transit is unambiguously an attack on the international system rather than on Washington alone. Second, a public war-risk insurance backstop, modeled on state reinsurance schemes, to break the private market's incentive to simply reprice Iranian coercion. Third, sustained pressure from the governments whose ships Iran currently waves through. China and India, the principal beneficiaries of Tehran's selective permissions, hold more leverage over the future of the Strait of Hormuz than any carrier strike group, and their interest in normalized trade is real.

None of this is cheap, and all of it is slow. But the alternative on offer is not stability at $70 crude; it is a world in which the busiest oil artery on the planet has a landlord. The 6,000 people waiting at anchor deserve better, and so does every economy that runs on what their ships carry.
