Rubio's Strait of Hormuz Problem Is a Problem for Everyone

On 22 May 2026, Secretary of State Marco Rubio announced that the United States and Iran had made "clear improvements" during ongoing negotiations. Hours later, speaking in separate remarks about the same body of water, he ruled out any future in which Iran might charge for passage through the Strait of Hormuz. No country, he said, would agree to pay. The statements sat uneasily alongside each other — not as a communication failure, but as a structural contradiction that runs through the entire US posture toward the Persian Gulf.

The Strait of Hormuz is not a metaphor. Roughly 20 percent of the world's oil and 20 percent of its liquefied natural gas pass through the 34-kilometre-wide channel between Oman and Iran each year. For four decades, the United States Navy has positioned itself as the guarantor of that flow — not out of disinterested generosity, but because controlling the chokepoint is a core instrument of dollarised petrodollar architecture and the sanctions regime that follows from it. Iran's Revolutionary Guard Navy, which physically patrols the strait's Iranian half, sees the arrangement differently: it has just announced that 35 vessels, including oil tankers and container ships, transited safely in the past 24 hours under its coordination and escort. The implication is not subtle. Iran is arguing that passage is not free — it is maintained, at risk, by Iranian military resources, and that work has value.

What Rubio described on 22 May — Iran's attempt to establish a toll system and to persuade Oman to participate — is therefore not a shakedown. It is a governance claim. Iran is asserting that the current arrangement, in which the US Navy provides security and the global shipping system pays nothing extra to the littoral state through whose waters it flows, is not a natural law. It is a political outcome, one that serves US interests, and it is open to renegotiation.

The UAE official who told Middle East Eye on the same day that there was a "50-50" chance of a US-Iran agreement on the Strait understood this perfectly. Oman and the UAE both sit on the strait's northern shore. Both benefit from the current open-seas regime. Neither can afford to be seen as a participant in a Iranian toll system backed by Washington, nor as an opponent of one Tehran is determined to pursue. The 50-50 framing is not hedging. It is an honest assessment of a genuine impasse: the US cannot agree to Iran's terms without undermining the sanctions architecture that depends on Hormuz's dollarised transit, and Iran cannot accept continued free passage without conceding the one leverage point it holds.

Rubio's insistence that "no country is ready to pay" for Hormuz passage is technically correct in the short term. No flag-of-convenience tanker operator wants a new line item. But it mistakes the negotiating position for the structural reality. The structural reality is that Iran already extracts value from the strait — not in tolls, but in the geopolitical overhead the United States pays to keep the waterway open and sanctionable. Every US carrier group rotation in the Gulf, every diplomatic mission to Riyadh or Abu Dhabi, every freeze of Iranian central bank assets at home and abroad — all of it is the price of a transit system that costs Tehran nothing in fees and a great deal in sanctioned isolation. Iran is proposing to make explicit what is currently implicit: if the US security guarantee is the price of free passage, then Iran will offer security, and someone will pay for it.

The problem for Washington is that the negotiation Rubio announced progress on cannot advance without addressing exactly this question. A diplomatic agreement with Iran that leaves the Hormuz governance structure untouched is an agreement that resolves nothing of substance — it manages the crisis, it does not resolve the underlying dispute about who controls the waterway and to whose benefit. If the talks are serious, they will eventually arrive at the toll question. And when they do, the choice will not be between paying and not paying. It will be between a toll denominated in dollars, enforced by US sanctions and US Navy presence, and a toll denominated in something else — perhaps a bilateral clearing arrangement, perhaps a genuinely multilateral fee collected through Oman — that reflects Iran's actual role in keeping the strait open.

Gulf monarchies are watching closely. Oman has historically positioned itself as the back-channel between Washington and Tehran; its potential participation in any Iranian toll framework would not be ideological solidarity with the Islamic Republic. It would be a cold-eyed calculation that a system with Iranian security guarantees and Omani administrative cover is more stable, and more durable, than one that depends on US goodwill which the past four years of maximum-pressure failure has demonstrated cannot be taken for granted. The UAE, Saudi Arabia, and Kuwait all have existing agreements with Iran on fisheries, pollution, and offshore demarcation. The Strait of Hormuz toll is a larger version of problems they have already solved at smaller scale.

Rubio's contradiction on 22 May — progress in negotiations, no tolerance for paying transit fees — is therefore not a messaging problem that a better communications shop can fix. It is the contradiction at the centre of US Iran policy, which has always wanted to extract Iranian concessions while offering nothing that Iran actually wants in return. The Hormuz toll is Iran's price. Washington can pay it in dollars, in institutional legitimacy, or in continued confrontation. It cannot avoid the bill forever.

What remains genuinely uncertain is whether the 50-50 odds cited by the UAE official reflect a real opening or the diplomatic fiction that all parties maintain while preparing for continued stalemate. The sources available on 22 May do not establish whether the Omani mediation has produced a written framework or remains at the level of exploratory signal. What they do establish is that the United States and Iran are talking, that the Strait of Hormuz sits at the centre of what they are talking about, and that Rubio's own public statements contain a contradiction he has not yet resolved. The talks may succeed. They may also be the most elaborate way of managing failure that both sides have found.

Monexus led with Rubio's announcement of diplomatic progress; the wire emphasis was on the positive framing of US-Iran engagement. This piece foregrounds the Hormuz governance question that the progress announcement necessarily raises.
