For a month Washington told the world that no nation may charge for passage through the Strait of Hormuz. The week its war with Iran reopened, it named itself the strait's Guardian and claimed a fifth of every cargo crossing the water. The toll lasted days before Washington let it lapse, and the lapse is the disclosure. A principle a great power invokes against its enemy and drops the moment the war makes it useful was only ever a lever, held in reserve until the price of pulling it fell.
On July 14, hours after the ceasefire with Iran collapsed into open fighting, the President of the United States announced that his country would from that point be known as the Guardian of the Strait of Hormuz. As Guardian, he wrote, it would be reimbursed at twenty percent on all cargo shipped through the water. He offered no method of collection. He named no legal authority for the demand.
Three weeks earlier his own Secretary of State had drawn the opposite line, and drawn it in absolute terms. Standing with Gulf partners and answering Iran's push for transit fees, he said that no country on Earth has the right to charge for the use of international waterways, and that such fees would never form part of any deal. Between the two statements nothing shifted in the law of the sea. The thing that shifted was the war.
The rule both men were speaking about is old and plain. The narrow version permits one thing and forbids a broader one. A state bordering a strait may bill for a real service it renders, a pilot aboard, a tug, a berth, at the same rate for every flag that passes. Charging for the bare right of passage falls outside it. A levy of one part in five on the value of the cargo is a toll on passage wearing the coat of a service fee. Shipping veterans told reporters that no state has tried to charge for transit through a strait in the modern era. By mid-July two of them had, in the same week, standing on opposite banks of the same conflict.
The American line had a seam in it from the beginning. Five days before the Secretary of State called the charge illegitimate for anyone, the President had already reserved it for the United States, promising no tolls in Hormuz unless they were imposed by and for America as the strait's protector. The Guardian toll pulled the thread on a position that was conditional the day it was announced, and the collapse of the ceasefire is what drew the thread tight.
Then, within days, the toll was gone. Washington let it lapse under legal exposure and the plain arithmetic of a market that had already sent freight and insurance costs climbing. Tehran, over the same stretch, traded its formal toll for a fee it now calls environmental protection. Both powers reached for the tollbook and both, for the moment, set it back down.
A principle that binds would have held under the test. This one was raised the week it turned useful and lowered the week it turned costly. That is the motion of a lever. For a month this analysis tracked Iran converting the strait into a sorting machine, a discount for friends and a mandatory fee and a missile for everyone off the list. The month's closing entry is that the country calling itself the strait's Guardian keeps the same tollbook in the same drawer, and opened it the first week the war made the reach worthwhile.
