For the first time in the crisis, we can read the actual text of what the deal says about the Strait of Hormuz, rather than inferring it from official characterisations. According to United States officials briefing the reporting, the memorandum of understanding provides that Tehran “will allow the safe passage of commercial ships without tolls for 60 days only.” It then provides that, following the sixty-day period, Iran “will conduct dialogue with the Sultanate of Oman to define the future administration and maritime services in the Strait of Hormuz in discussion with other Persian Gulf littoral states in line with the applicable international law and the sovereign rights of coastal states of the Strait of Hormuz.” Iran’s accompanying position is that “under international law, it is not possible to levy a toll on passage through the Strait of Hormuz, but charges for services provided will be collected.”
This is a remarkable passage, and reading it carefully cuts two ways. On the one hand, the text adopts — almost verbatim — the institutional framework this site has argued for since April. On the other, it contains a sunset that turns the whole arrangement into a sixty-day bridge to an undefined destination. This post reads the text in both directions, because the deal’s treatment of the strait is best understood as a vindication of the site’s framework wrapped around a deferral that the framework warns against.
The vindication: the text speaks the site’s language
Consider the vocabulary of the operative clause. “Future administration and maritime services.” “In discussion with other Persian Gulf littoral states.” “In line with the applicable international law.” “The sovereign rights of coastal states.” And, from the Iranian position: “it is not possible to levy a toll… but charges for services provided will be collected.” Every one of these phrases is a phrase this site has been using, and arguing for, across forty-odd posts.
“Maritime services,” not tolls, is the UNCLOS Article 26 distinction the site has drawn from the start: a natural strait may not charge for passage but may charge for specific services rendered. The text adopts that distinction explicitly. “In discussion with other Persian Gulf littoral states” is the joint-riparian, multi-state framework the Iran-Oman administration post argued the two-bank geography requires, and which the precedent-problem post located in the Strait of Malacca cooperative model. “In line with applicable international law and the sovereign rights of coastal states” is the UNCLOS framework the founding UNCLOS-vacuum post identified as the governing standard.
The Iranian government, in the text it signed, has abandoned the vocabulary of the unilateral framework — the rial-denominated, sanctions-differentiated, IRGC-administered toll of the twelve-article statute analysed in the sovereignty-law post — and adopted the vocabulary of a lawful, multilateral, services-based chokepoint authority. That is a real movement, and the site should acknowledge it plainly: the deal’s text describes the institution the site has been arguing for, in the site’s own terms. The framework has, at the level of language, prevailed.
The deferral: “for 60 days only”
But read the structure, not just the vocabulary. The text does two distinct things. First, it grants no-toll safe passage “for 60 days only.” Second, it commits Iran to a dialogue, after those sixty days, to “define” the future administration and maritime services. The no-toll guarantee is temporary and explicit; the permanent regime is undefined and deferred. The text does not establish the institution. It establishes a sixty-day window of free passage and a promise to negotiate the institution during or after it.
The phrase “for 60 days only” is the critical one. It means the free passage that has allowed the reopening to begin is not a permanent right; it is a sixty-day concession. On day sixty-one, absent a concluded agreement on “future administration and maritime services,” the legal basis for no-toll passage lapses, and the question of what Iran may charge — and how, and to whom — reopens with no settled regime in place. The text guarantees free passage exactly long enough to get the strait reopened and the war ended, and no longer. What replaces it is a dialogue whose outcome the text does not specify.
Two ways the sixty days can end
The site reads two possible destinations for the sixty-day bridge, and the difference between them is the difference the whole crisis has been about.
The first destination is the institution. The sixty-day dialogue, conducted by Iran and Oman with the other Gulf littoral states, under international law, produces a constituted joint chokepoint authority — civilian, equal-access, charging a genuine Article 26 service fee calibrated to the cost of navigation and safety services, settling in convertible currency, integrated with the thirty-eight-nation security mission as its security layer. On this path, the sixty-day no-toll window is the bridge to the permanent institution, and the vocabulary of the text becomes the substance of a working authority. This is the outcome the site has argued for, and the text leaves it fully available.
The second destination is the relapse. The sixty-day dialogue stalls — perhaps because, as the nuclear-basket post warned, strait management is entangled with the nuclear file and the nuclear file deadlocks; perhaps because the Gulf states and Iran cannot agree terms; perhaps because the political will that the Lucerne walk-out showed to be volatile simply fails. On this path, day sixty-one arrives with no constituted authority, the no-toll guarantee lapses, and Iran reverts to the position the text papered over: that it controls the strait and may charge for “services” on its own terms, through the sanctioned Persian Gulf Strait Authority, in the bifurcated configuration the bifurcating-strait post documented. The vocabulary remains lawful; the substance reverts to unilateral.
The text accommodates both destinations because it defines the bridge but not the far bank. It is, precisely, a sixty-day deferral of the institutional question, dressed in the vocabulary of the institutional answer.
Why the sunset matters for behaviour now
The “for 60 days only” sunset is not just a future risk; it shapes behaviour during the sixty days. Consider the operator class and the underwriters. A shipowner deciding whether to commit a vessel to a Hormuz transit, and an underwriter deciding whether to cut the war-risk premium the freight-tail post documented at four thousand times the pre-crisis level, both have to reckon with the fact that the no-toll, safe-passage regime is guaranteed for only sixty days. They cannot treat the reopening as permanent, because the text does not make it permanent. They have to price the risk that on day sixty-one the regime changes — that tolls or restrictive “service fees” appear, that the bifurcation returns, that passage becomes conditional again.
This is why the reopening is a trickle rather than a flood, and why the freight and insurance numbers normalise slowly. A sixty-day guarantee does not support the multi-year commercial planning that routine high-volume transit requires. Long-term charters, sustained capacity deployment, and normalised premiums all depend on a durable regime, and the text provides a temporary one. The sunset is, in effect, a sixty-day question mark hanging over every commercial decision about the strait, and the operator class is responding to it rationally, by waiting to see what day sixty-one brings.
The deliverable the sixty days needs
The constructive reading is clear and the text makes it achievable. The sixty-day dialogue should produce the institution — a constituted joint Iran-Oman-Gulf chokepoint authority, on the Malacca cooperative model, charging a genuine Article 26 service fee, that converts the temporary no-toll window into a permanent equal-access regime. The text’s own vocabulary describes that authority; the sixty-day dialogue is the venue to build it; the only thing missing is the decision to treat the dialogue as institution-building rather than as a placeholder.
The site has argued throughout that the strait needs an institution, not an agreement. The deal’s text is, in a sense, the closest the crisis has come to conceding the point: it adopts the institution’s vocabulary and commits to a dialogue to define it. What it does not do is build it, and it puts a sixty-day clock on the space in which it could be built. The vocabulary has been won. The substance is a sixty-day question. What happens on day sixty-one depends on whether the dialogue the text promises produces the authority the text describes. The comparison page sets out that authority. The rate schedule prices the service fee the text authorises. The calculator prices a transit. The deal speaks the site’s language; whether it builds the site’s institution is the work of the next sixty days.
