Hormuz as hostage: the strange arithmetic of a strait nobody is allowed to close

By the time Iranian negotiators touched down in Switzerland on the evening of 20 June 2026, the diplomatic theatre had already been written. President Donald Trump told Iranian state television that no toll would be charged in the Strait of Hormuz unless the United States itself imposed one. Reuters reported the remarks at 22:16 UTC; Al Jazeera's breaking desk had them on the wire three hours earlier in slightly different form. The same evening, a Reuters dispatch noted that Washington was publicly disputing Iranian claims about closing the waterway as the delegations prepared to sit down. The New York Times framed the meeting as "the next phase of talks to end the war in Iran" — a phrase that, in passing, tells the reader this publication is now living inside an active war it had not been covering as such two months ago.

The pattern, in plain terms, is this: a narrow stretch of water has become the central negotiating asset in a conflict over the future of the Iranian state, the price of oil, and the credibility of American guarantees. Everyone at the table knows the strait matters. Nobody at the table is willing to say, on the record, what closing it would actually cost — or what reopening it would be worth.

A waterway with a price tag

The Strait of Hormuz carries roughly a fifth of the world's traded oil. Any sustained disruption moves spot prices within hours. That gives whoever threatens to close it, or whoever promises to keep it open, a leverage that exists independent of any tank, missile, or ballot box. Trump's statement — relayed by Two Majors via Telegram on 20 June at 22:37 UTC — was designed to make that leverage look like a gift. No toll, he said, unless Washington itself decides there should be one. It was an offer to Iran and a warning to everyone else. The offering hand and the clenched fist were the same gesture.

Iranian counter-claims, the Reuters dispatch from 00:10 UTC on 21 June notes, assert the opposite: that Tehran retains the ability to close the strait, and that any "memorandum of understanding" with Washington is provisional. Al Jazeera's reporting on the same memorandum — published 21:54 UTC the previous day — confirms a 60-day initial window in which no tolls are levied, but explicitly states the document "does not rule out future tolls in the strait." So both readings of the same text are accurate. That is not a diplomatic failure. It is the point of a memorandum.

Why the West can't say what it means

The official Western line — voiced through the State Department and echoed in the Reuters wires — is that Iran cannot lawfully close an international waterway to commercial traffic, and that any attempt to do so would meet a military response. That is the line the press is reporting. It is also a line the press is not, generally, asked to scrutinise. The legal case for treating the strait as a global commons is genuinely strong, and the case for treating it as a chokepoint that an aggressor state might exploit is genuinely serious. But the framing leaves out the middle fact: that for forty years the United States has, in effect, run the strait's security as an extension of its own naval posture in the Gulf, and that the current crisis is at least in part a product of that posture.

If the strait is genuinely a neutral global commons, then the question of who sets the price of passage is a question for the international community, not for Washington and Tehran alone. If it is a chokepoint that America has chosen to police as part of its wider regional role — and that choice is, on the evidence, exactly what it has been since the 1980s — then the current argument is not about legality at all. It is about who pays for the policing, and who gets the diplomatic credit for it.

The Iranian position, stated flatly

Iranian state media, including outlets like PressTV and Tasnim, are reporting that Tehran regards any future toll regime as a sovereign prerogative, and that the current 60-day arrangement is a confidence-building measure rather than a permanent concession. That position is, on the face of it, easier to defend inside Iran than the American one is inside the United States: a country that has just fought a war is, by definition, a country that has bought the argument that it can be denied something. The Trump framing — "no toll unless we impose one" — concedes more than it appears to. It concedes that a toll is a normal instrument of policy. It only reserves the right to set the rate.

This publication reads the sequence as follows: the strait is being used as a hostage in a negotiation whose real subject is the shape of the Iranian state after the war. The two sides are not arguing about whether the waterway should generate revenue. They are arguing about who gets to decide.

What it costs if the arithmetic fails

The honest risk picture is not hard to draw. If the memorandum holds and the 60-day window passes without incident, the question of tolls returns to the table with whatever leverage each side has managed to accumulate in the interim. If the memorandum collapses — and the conflicting Iranian and American claims about its terms are themselves a sign of strain — then the strait becomes a live military question within hours. Brent and Dubai benchmarks will move before the diplomats have finished their post-mortems. Insurance war-risk premia for Gulf shipping will follow within a day. The downstream effect on import-dependent economies in Asia and the Mediterranean is then mechanical, and falls hardest on the buyers who can least absorb it.

What remains genuinely uncertain, on the sources available to us, is whether the Swiss talks are intended to produce a political settlement or merely to manage a phase. The New York Times piece describes them as "the next phase of talks to end the war," which is a phrase that could mean either. The Reuters reporting from 00:10 UTC on 21 June records the American pushback on Iranian closure claims as the talks begin, not as a position arrived at after them. The memo's silence on what happens after 60 days is, in the end, the most honest description of where this stands: a confidence-building measure that builds confidence only as long as both sides agree, in private, not to test it.

This piece treats the Strait of Hormuz as a financial and diplomatic instrument first, and as a military question second — a frame the wires have so far been reluctant to adopt on their own.
