On 13 July 2026, President Trump declared that the United States would become, in his words, “THE GUARDIAN OF THE HORMUZ STRAIT,” and that as guardian it would be “reimbursed, at the rate of 20% on all cargo shipped, for any and all costs necessary to do the job of providing safety and security to this very volatile section of the World.” He added that this was “a matter of FAIRNESS,” that “the process and formation will begin immediately,” and that the United States would reimpose its naval blockade, targeting Iranian ships while other nations’ vessels paid the fee. He declared the mid-June ceasefire over. United States forces had struck Iran on Sunday; Iran’s Revolutionary Guards said they attacked United States bases in Kuwait and Bahrain on Monday. Brent crude jumped more than five per cent toward eighty dollars, unwinding in a day much of the recovery this site tracked to seventy-two. A spokesman for Iran’s Khatam al-Anbiya said Iran “will not, under any circumstances, allow the US to interfere in the management of the Strait of Hormuz.”<\/p>\n
This site has spent nearly a hundred posts applying one consistent test to the question of who may charge for passage through the Strait of Hormuz. It applied that test to Iran’s toll and found it wanting. Intellectual honesty requires applying the identical test, without fear or favor, to the United States’ proposed twenty per cent. When we do, the result is unambiguous: the guardian’s toll fails the same test Iran’s toll failed, and it fails it more severely. This post applies the test, because the site’s credibility rests on judging the proposals by their structure rather than by their sponsor.<\/p>\n
The test this site has used throughout derives from the United Nations Convention on the Law of the Sea and from the practice of the world’s functioning chokepoint authorities. It has four parts, set out most fully in the post on tolls versus service fees<\/a>. A charge for passage through a natural strait is legitimate only if: it is payment for specific services actually rendered to the vessel, not a charge by reason of passage; it is calibrated to the cost of those services, not to the value of the cargo; it is non-discriminatory across flag states; and it is levied by a body with standing to administer the strait, meaning a riparian authority, not an arbitrary third party. Iran’s toll failed the first three tests. The guardian’s toll fails all four, and the fourth failure is the most striking of all.<\/p>\n Begin with the fourth test, because it is where the guardian’s toll is most obviously void. Iran, whatever the defects of its toll, is a riparian state. It borders the strait; its territorial waters carry part of the traffic; under UNCLOS it has at least the standing of a coastal state, however constrained that standing is by the transit-passage regime. The post on the other shore<\/a> and the post on the Iran-Oman administration<\/a> traced how the strait’s two banks, Iranian and Omani, give those two states a genuine, if limited, role in any governance arrangement.<\/p>\n The United States is not a riparian state. It does not border the Strait of Hormuz. It has no territorial sea there, no coastal-state standing, no sovereign claim to any part of the water. Its proposed toll rests not on any territorial right but on the assertion of a self-appointed role, “guardian,” backed by naval force. This is a toll levied by a great power on a waterway it does not border, justified by the military presence it can project there. There is no provision in the law of the sea, and no precedent in the practice of chokepoints, for a non-riparian state to charge for passage through a strait it happens to be able to dominate militarily. The Suez Canal is charged for by Egypt, which built and owns it. The Panama Canal is charged for by Panama, through which it runs. No third power charges for either. A United States toll on Hormuz is a toll by a state with no standing whatever, which is a category the law does not contemplate because it is the category the law exists to prevent.<\/p>\n Now the second test, calibration to cost. Iran’s toll of roughly one to two million dollars per vessel, or about one dollar per barrel, already failed this test, as the toll-versus-service-fee post showed, because it was calibrated to cargo value rather than to the cost of any service rendered. The guardian’s toll fails the same test on a scale an order of magnitude larger. Twenty per cent of all cargo shipped is, on a very large crude carrier carrying perhaps one hundred and fifty million dollars of oil, a charge of thirty million dollars per transit. That is roughly fifteen times what Iran was charging. Across the annual cargo value that transits Hormuz, twenty per cent would generate figures in the hundreds of billions of dollars a year.<\/p>\n Set that against the stated justification: reimbursement for “the costs necessary to do the job of providing safety and security.” The cost of providing that security is the cost of a naval mission. The thirty-eight-nation demining and escort mission the post on clearing the residue<\/a> examined costs, generously estimated, a few billion dollars a year. A toll that generates hundreds of billions to reimburse a cost of a few billion is not reimbursement. It is a levy on cargo value dressed as a security fee, and the gap between the twenty per cent charge and the actual cost of the service is the measure of how far it departs from a genuine service fee. The word “reimbursed” implies recovery of costs incurred. Twenty per cent of cargo recovers those costs many times over, which means it is not reimbursement but taxation, and taxation of passage is precisely what the law forbids.<\/p>\n The third test, non-discrimination, the guardian’s toll also fails, and openly. The proposal explicitly distinguishes Iranian vessels, which are blockaded, from other nations’ vessels, which pay the twenty per cent. A charge that applies to some flags and not others, coupled with a blockade of one state’s shipping, is discriminatory by design. This is the same defect the post on Iran’s sovereignty law<\/a> identified in the Iranian framework, which discriminated against vessels of states Iran deemed hostile. Both proposals sort ships by the political identity of their flag rather than treating all traffic on equal commercial terms, and both thereby convert a transit charge into an instrument of coercion. The guardian’s toll is not a neutral fee for a service available to all. It is a fee for some and a blockade for others, which is the opposite of the equal-access principle that makes a chokepoint authority an authority rather than a weapon.<\/p>\n The first test, that the charge be payment for a specific service rather than a charge by reason of passage, is where the guardian framing does its work, and it is worth seeing through. By calling the United States the “guardian” and the toll a “reimbursement” for “safety and security,” the proposal casts the charge as payment for a protective service. But the service being charged for is protection of the very passage being charged for. This is the structure of a protection arrangement in which the party controlling access charges for safe passage through the danger its own control creates. The post on the strait as hostage<\/a> described how an ungoverned chokepoint becomes a lever; the guardian’s toll is that lever monetized. Charging twenty per cent for “safety and security” through a strait one has militarized, while blockading a rival’s ships to demonstrate the danger, is not the provision of a service freely contracted. It is a charge by reason of passage with a security label, and the label does not change what it is.<\/p>\n The tragedy of the guardian’s toll is what it displaced. In the days before Trump’s announcement, Iran and Oman had presented the United States with a joint proposal to administer the strait, and that proposal, whatever its flaws, was the closest anyone had come to the legitimate answer this site has argued for. Under the Iran-Oman plan, fees would be collected in consultation with the international community and through the International Maritime Organization, shared between the two riparian states, and used for environmental-risk assessment, rescue, and technical support, explicitly on the model of the Strait of Malacca cooperative mechanism that this site has repeatedly named as the template. Bordering states cooperating to provide navigational safety and environmental protection, with users contributing to the associated costs, is the Article 26 service-fee model done correctly, by the states with standing to do it.<\/p>\n The Iran-Oman plan had one genuine flaw, and it is the familiar one: Oman insisted the payments be voluntary, preserving the principle of free navigation, while Iran insisted they be compulsory, and reportedly believed the system could generate forty billion dollars a year. On the law, Oman is right. A voluntary contribution to the cost of navigational services is lawful under Article 26; a compulsory charge by reason of passage is not. The disagreement between Muscat and Tehran was precisely the line between a legitimate service fee and an unlawful toll, and it was a resolvable disagreement, because it was a disagreement within the correct framework. The United States response was not to help Iran and Oman resolve it on the lawful side of the line. It was to blow up the framework entirely and assert a twenty per cent toll of its own, by a non-riparian power, at fifteen times the rate, with none of the Malacca-model legitimacy the Iran-Oman plan at least reached for.<\/p>\n Step back and see the whole. The strait now has three would-be toll collectors: the Persian Gulf Strait Authority’s unilateral Iranian charge, the Iran-Oman joint plan, and the United States guardian toll, and the ceasefire that was supposed to resolve the question has collapsed into renewed strikes and a reimposed blockade. This is the outcome the post on the ending crisis<\/a> warned of when it argued that the vacuum would outlast the calm. The vacuum did not merely persist. It produced a scramble. With no legitimate authority governing the strait, the waterway has become a prize that each powerful actor present claims the right to tax, and the claims now collide: Iran’s, Iran-and-Oman’s, and the United States’. The absence of an institution has not left a neutral gap. It has left a contest, and the contest is now armed.<\/p>\n This is the deepest vindication of the argument the site has made from the beginning, and the least welcome. When there is no recognized authority to charge for a chokepoint on legitimate terms, the charging does not stop. It multiplies, and it goes to whoever can enforce it. The guardian’s toll is what tolling looks like when might replaces right: not a service fee set by a civilian authority accountable to the users, but a levy set by the strongest military present, justified by the danger that military itself embodies. The post on the precedent problem<\/a> warned that tolling a natural strait would set a precedent every chokepoint state could invoke. The guardian’s toll sets a worse one: that any great power able to dominate a strait may tax the world’s passage through it. If that precedent holds at Hormuz, it is available at Malacca, at Bab-el-Mandeb, at every chokepoint a great power can reach.<\/p>\n The site’s position is the same one it has held throughout, applied without exception. A charge for passage through the Strait of Hormuz is legitimate only if it is a cost-based service fee, levied by a riparian authority, on equal terms for all flags, for services actually rendered. Iran’s toll failed that standard. The Iran-Oman plan approached it and stumbled on the voluntary-versus-compulsory line. The United States guardian toll fails it completely, on every one of the four tests, and adds to the failure the absence of any riparian standing at all and a rate fifteen times Iran’s. The site opposed the Iranian toll on principle. It opposes the guardian toll on the identical principle, and the principle does not bend for the sponsor.<\/p>\n The answer remains what it has always been: a treaty-backed, civilian, equal-access, cost-based transit authority, administered by the riparian states in cooperation with the users and the maritime community, on the Malacca model that the Iran-Oman plan reached toward. Such an authority is the only configuration under which the strait is charged for legitimately or not charged for at all, and it is the only alternative to the armed scramble now under way. The comparison page<\/a> sets out that authority. The rate schedule<\/a> prices a transit at the cost-based service-fee level, a small fraction of twenty per cent of cargo. The calculator<\/a> prices a specific transit against it. The guardian’s toll is not the institution the strait needs. It is the clearest proof yet of what the absence of that institution produces: a waterway that the powerful line up to tax, each in turn, until the strongest wins and the world pays.<\/p>\n Sources: CNBC, “Trump proposes 20% toll on cargo through Strait of Hormuz; restarts Iran blockade,” 13 July 2026; Bloomberg, “Trump Says US Will Be Reimbursed 20% Rate For Hormuz Traffic,” 13 July 2026; Al Jazeera, “Trump says US will become ‘guardian’ of Strait of Hormuz and collect tolls,” 13 July 2026; Al Jazeera, “Oil prices jump as US and Iran trade attacks over Strait of Hormuz,” 13 July 2026; Newsweek, “Trump Floats US Tolls as Control Fight Over Hormuz Strait Deepens”; NBC News, “Iran and Oman propose fee plan for Strait of Hormuz, sources say”; France 24, “Iran, Oman mull charging Strait of Hormuz ‘maritime service fees,'” 23 June 2026; SAFETY4SEA and The Week on the Iran-Oman voluntary-versus-compulsory dispute and the forty-billion-dollar estimate; statements by President Trump and Iran’s Khatam al-Anbiya spokesman; United Nations Convention on the Law of the Sea, 1982, Articles 26 and 37-44; this site’s prior analyses on tolls versus service fees (14 June), the precedent problem (16 June), the other shore (1 June), the Iran-Oman administration (16 June), the sovereignty law (23 May), the strait as hostage (23 June), clearing the residue (29 June), and the ending crisis (30 June).<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" On 13 July 2026 Trump declared the US ‘Guardian of the Hormuz Strait’ and claimed a 20% toll on all cargo as ‘reimbursement’ for safety and security, reimposing the blockade and declaring the ceasefire over.
