Tehran publishes Hormuz transit rules after rocky council vote, signals 60-day fee holiday

Iran's Supreme National Security Council published the operational architecture for the so-called Islamabad Memorandum of Understanding on the afternoon of 18 June 2026, in a sequence of urgent statements that ran for roughly half an hour on Iranian state-aligned channels. The council directed the Persian Gulf Waterways Authority to field transit requests, told commercial vessels to use a designated route at designated times, and — most consequentially — confirmed a 60-day fee waiver for shipping that applies during the initial implementation window.

The publication is the first concrete procedural translation of an agreement whose political substance has been debated in Tehran for weeks. The transit rules also expose an internal fault line: according to an Iranian source cited by Middle East Spectator on Telegram at 20:10 UTC on 18 June, the Memorandum of Understanding "failed during the first round of voting in the Supreme National Security Council" and was only adopted in a second round. Whether that account is accurate or contested is itself part of the story, and is examined below.

What the council actually ordered

The procedural text is short and tightly drafted. Vessels seeking to transit the Strait of Hormuz must submit their request to the Persian Gulf Waterways Authority. The Authority is to "process and respond to requests quickly and with priority" and to publish "implementation arrangements and technical details" for passage. Commercial ships, the council said, must follow the announced route at the announced time, "so that the possibility of traffic can be gradually increased."

The headline financial concession is the 60-day fee waiver. Under Paragraph 5 of the Memorandum, "no fees will be imposed on applicants for a period of sixty days," with the council noting that the Iranian government will absorb the cost of administration during the introductory period. Al-Alam Arabic broadcast the relevant statement at 18:43 and 18:44 UTC; Tasnim News English and PressTV carried the same passage at 18:42 and 18:33 UTC respectively, and Al-Alam Farsi published a summary at 18:45 UTC. The cross-platform uniformity across state-aligned outlets suggests the text was distributed from a single council press release.

The council also folded two adjacent items into the statement. On mine clearance — a longstanding operational concern in the waterway — the council said "the necessary measures will be taken in accordance with law" and, in the Al-Alam Arabic readout at 18:49 UTC, referenced Paragraph 5 of the Memorandum as the legal anchor. That detail matters: by tying mine-clearance obligations to the Memorandum rather than to a separate maritime-security instrument, Tehran is asserting that the entire transit regime, safety and revenue included, is governed by the Islamabad text.

The contested vote

The narrower political story is the council vote itself. The Middle East Spectator bulletin at 20:10 UTC quoted an "Iranian source" saying the Memorandum "failed during the first round of voting" and passed only on a second round. No wire service has corroborated the account, and the bulletin does not name the source or specify how many council members voted in each round. It is also possible that the first round referenced a different draft than the one ultimately circulated; Iranian security-council deliberations are not ordinarily minuted in public, and the body's composition includes both civilian and military principals whose internal politics are opaque from outside.

The episode nonetheless sits inside a familiar pattern. Iranian institutional ratification of major foreign-policy bargains typically involves a public endorsement long after internal haggling has concluded. The very existence of the 60-day waiver — a real fiscal cost the government has agreed to absorb — implies that the political case for the deal needed sweeteners to assemble a majority. Tehran's willingness to publish that a vote occurred, even via a third-party Telegram channel rather than in its own communiqués, signals a deliberate leak by someone inside the process who wanted the fragility of the consensus on the record.

Why the procedural detail matters

A 60-day fee holiday is not a trivial concession. The Strait of Hormuz carries a significant share of seaborne oil flows; even a temporary elimination of transit levies, however small in absolute terms relative to freight rates, reframes the political economy of the corridor. It tells international shippers, insurers and charterers that Tehran is prepared to use pricing as a sweetener to make the new regime legible in the first weeks of operation — the very period in which a single incident could harden Western suspicion and push vessels toward longer Cape of Good Hope routings.

The corridor politics are also being shaped in parallel by a separate Tehran process on the broader file. The procedural text references Paragraph 5 of the Memorandum as the governing clause for both fee policy and mine clearance, which suggests the council intends the Islamabad instrument to be read as the umbrella document for everything Hormuz-related until further notice. That is a deliberate legal posture: it denies space for a competing framework — whether a UN Security Council product, a bilateral US-Iran instrument, or an Omani-Kuwaiti alternative — to be layered on top without Iranian consent.

Counter-reads and what remains uncertain

There are at least three plausible alternative readings of the same evidence, and a careful account has to keep them visible.

First, the most sceptical read: the council vote really did fail in the first round, the Memorandum is politically weaker than its public endorsement implies, and the 60-day waiver is the price of holding a coalition together. On that reading, the procedural implementation is more fragile than the cross-outlet uniformity suggests, and any sign of internal dissent over the next weeks will matter disproportionately.

Second, the proceduralist read: the first-round reference is shorthand for a technical amendment cycle rather than a political defeat; the Memorandum was refined and re-presented, and the second-round vote was a formality. The Middle East Spectator bulletin would, on this reading, be a leaked partial truth designed to look like instability.

Third, the leverage read: the Iranian source deliberately seeded the first-round account to signal to Western interlocutors, and to Israel and the Gulf states, that the deal survived a real internal fight — and that further pressure on Tehran will be more expensive than it looks, because the consensus has already paid a political cost.

The published evidence does not adjudicate between these. The sources do not specify the council vote count, do not name dissenters, and do not detail whether the waivers and mine-clearance language survived the second round unchanged. The mine-clearance reference to Paragraph 5 is, however, the most concrete published anchor for tracking whether the legal architecture drifts in implementation.

Stakes

If the regime holds, the practical effect over the next sixty days is that commercial shippers face a lower-friction, lower-cost Hormuz transit than at any point in the recent escalation cycle, and Tehran gets a measurable uptake figure to point to when the waiver expires. If it does not hold — if a council faction withdraws consent, or a maritime incident triggers a security review — the same procedural text becomes a record of what was attempted and where it broke.

For shippers, insurers and energy desks, the operative variables for the rest of June are: whether the Persian Gulf Waterways Authority actually publishes the route and schedule details on time, whether fee invoices start to appear at the end of the sixty-day window, and whether mine-clearance language is invoked as a separate security instrument or remains bound to Paragraph 5 of the Memorandum. The first two are observable on a shipping-clerk desk; the third is observable in any future Iranian statement that departs from the present language.

Desk note: Monexus has framed this around the procedural text and the contested council vote, both of which are sourced to Iranian state-aligned channels and a single uncorroborated Telegram bulletin. Where the sources disagree or fall silent, the piece says so in plain language rather than papering over the gap. Wire coverage from Reuters, the BBC and Al Jazeera English is not yet on the record for the 18 June procedural statement and has not been used as a stand-alone factual basis here.
