US Imposes 20% Toll on Strait of Hormuz Shipping

Three weeks ago the United States told the world that nobody may charge for passage through the Strait of Hormuz. Marco Rubio said it plainly when Tehran floated a transit fee: Iran has no right to tax the sea. On Monday Donald Trump announced that the United States would be reimbursed at a rate of 20 percent on all cargo shipped through the same waterway, in return for providing what he called safety and security, and that America would henceforth be known as the guardian of the Hormuz strait. He wrote it in capital letters. The principle Washington condemned in June is now American policy, with the rate written into it.

It is worth being precise about how strange this is. Iran at least borders the strait. The United States does not. James R. Holmes, who holds the chair of maritime strategy at the US Naval War College, made the legal point about Iran's version of the scheme in terms that apply with more force to Trump's: there is no provision in international law, he said, for a coastal state charging for passage through a natural waterway, whether you call it a toll or a fee or whatever. The right of unobstructed and untolled transit has been the settled rule since the Law of the Sea convention took effect in 1994, and for four decades before that it was the thing the US Navy existed to enforce. Freedom of navigation was never a favour Washington did for its allies. It was the load-bearing wall of a trading system the United States built and profited from more than anyone. This week the wall acquired a meter.

None of this is really about Iran. It is about money. The White House asked Congress on 24 June for $87.6 billion to keep this war going — $67 billion of it for the Pentagon, including $21 billion for munitions alone, with $11.1 billion for farmers hurt by the fallout stapled on to help it pass. That request is still sitting there. The Pentagon had wanted something closer to $200 billion in March and was refused. Republicans facing midterm elections in four months are being asked to vote more money for a war their voters have soured on, and they do not want to. A 20 percent levy on the fifth of the world's oil that moves through Hormuz is what a war looks like when the legislature will not pay for it and the president decides the cargo will. Trump has found a revenue source that requires no vote.

Whether a single dollar of it is ever collected is a different question. The strait is now claimed by two rival toll authorities, each insisting the other's is illegitimate. Iran's Revolutionary Guard struck the Cyprus-flagged container ship GFS Galaxy for taking what it called an unauthorised route, and Tehran's Persian Gulf Strait Authority now says vessels that decline its preferred lane forfeit any guarantee of safe passage; Iran then declared the waterway closed until American interference ends, a closure US officials flatly deny is in effect. Both of these are protection rackets with a flag on them. The shipping industry has drawn the obvious conclusion and stopped going: six vessels crossed the strait between Thursday and Friday, against the eighteen to twenty-two a day that were transiting earlier this month. Brent settled at $78.82 on Monday, its highest since 22 June and up about 5 percent on the week — a number that says the market believes this is bad but survivable, and that it has priced far worse before. The traffic figure is the one to watch, not the price. A toll on a waterway nobody dares enter collects nothing.

The most damning verdict on all this came from the smallest party to it. Oman has drafted a plan, reported by CNN while Iran's foreign minister was in Muscat, to split the strait into two corridors: a southern lane through Omani territorial waters where navigation would run on prewar terms, and a northern lane through Iranian waters that would need Tehran's approval. The detail that matters is the one Muscat wrote in explicitly — under the Omani plan, no tolls would be charged on either route. The one government in this story with no navy worth the name, and the most to lose from a closed strait, has produced the only proposal that actually complies with the law of the sea. Iran's delegation could not approve it in Muscat and went home to think. Washington, which used to write plans like that, is now the reason one is needed.

The war itself got harder to end in the meantime. American forces hit dozens of Iranian targets over the weekend, including the refinery city of Abadan, and used one-way attack sea drones in combat for the first time — a milestone that will be studied in every navy that expects to fight in a narrow sea, and one that quietly hands Iran's own asymmetric playbook back to it. Iran fired on US bases in Kuwait, Bahrain, Jordan, Oman and Qatar. Washington's ambassador to NATO summed up the diplomatic mood by describing Iran as a country controlled by crazy people. And new satellite imagery shows Iran rebuilding damaged nuclear infrastructure at the Parchin military complex — the very thing the June memorandum was written to prevent. That memorandum, which was supposed to end the fighting and lift the naval blockade, has now been hollowed out from both ends at once: Tehran is rebuilding what it promised to abandon, the blockade is back, and Trump's careful gloss on it — that it stops only Iran's own ships and its customers — is a distinction that will be lost on any shipowner deciding whether to send a hull through the Gulf.

Europe drew its conclusions within forty-eight hours. On Monday in Paris, Emmanuel Macron hosted Volodymyr Zelensky and the leaders of Denmark, Germany, Italy, the Netherlands, Norway, Spain, Sweden and the United Kingdom to sign a joint declaration establishing an Integrated Anti-Ballistic Missile Coalition, with the stated goal of building a shared ballistic-missile defence capability for Europe and with Ukraine's Freya air-defence project as its first beneficiary. Germany, in the same stretch of days, moved to buy American Tomahawks. That pairing looks like European weakness: still shopping in Washington while talking about autonomy. It is the opposite. Europe is buying the American weapons it needs now and building the architecture it needs later, because it has just watched the United States put a price tag on a security guarantee that was supposed to be a principle. You do not construct your own missile-defence architecture with nine partners because you trust that someone else's will be there. You do it because the guarantor has started itemising the bill, and you have understood that next time the item could be you.

The most instructive thing in the week, though, is not happening in the Gulf at all. Ukraine has never had a guarantee to lose, and it spent the week demonstrating what a country does instead. On Monday Ukrainian drones blacked out the entire occupied Crimean peninsula — two and a half million people, an area the size of Wales — after striking the transition point that lands the Kuban-Crimea power bridge, fourteen and a half kilometres of undersea cable, along with eleven other energy nodes. Its unmanned forces have been methodically emptying the Sea of Azov: the shadow-fleet anchorage north of the Crimean bridge held around a hundred vessels on 1 July and roughly twenty by the 8th, with thirteen more struck in a single night. And on 10 July Oleksandr Syrskyi reported that Russia's much-heralded 2026 offensive had failed to take any of its objectives despite an almost two-to-one advantage in men and equipment; the number of active fronts has fallen from thirteen to six or seven, the rate of Russian advance has more than halved, and Russia is losing about 32,000 killed and wounded a month. None of this was granted to Ukraine at a summit. It was manufactured, largely at home, and Washington's most useful contribution in the same week was a licence letting Kyiv build Patriot interceptors itself.

Set the two campaigns side by side and the contrast is brutal. Both Washington and Kyiv spent this month trying to choke an adversary's oil. The United States put a fleet across the world's most important waterway, told every shipowner on earth to pay a fifth of the value of their cargo, and has so far mostly succeeded in emptying the strait. Ukraine, with drones costing a rounding error of the $67 billion the Pentagon is asking for, simply destroyed the refineries: Russian crude processing fell to 3.91 million barrels a day this month, the lowest in twenty-one years, more than 1.4 million barrels below last year's average, after at least 194 strikes on refining in the first half of 2026. Petrol shortages now run at about a third of demand and reach some 50 million Russians. One campaign taxes the world to pressure an enemy. The other costs the world nothing and has taken 40 percent of that enemy's refining capacity offline. Whatever else Europe's defence ministers learned in Paris this week, they can read that ledger.

That is the lesson everyone in Paris has now absorbed, and it is the thread that runs from the Azov Sea to the Strait of Hormuz. The last global brief argued that the West can win its wars but cannot make its ceasefires hold, and that only what someone is willing to physically enforce stays put. This week the United States agreed — and then decided to charge for the enforcement. What it has not reckoned with is that the ability to enforce is exactly the thing its allies are now learning to build for themselves, and that the toll booth on the Hormuz strait is the most persuasive argument for European and Ukrainian self-reliance that anyone has made in years. Watch the transit counts in the Gulf, and watch whether Asia — which needs that strait far more than America does — pays, protests, or quietly starts hedging. The bill for the guardian is going to be presented to the countries least willing to accept that America is the one holding the ledger.
