Hormuz open to friends, shut to enemies

Iran's foreign minister told Japanese media the strait is blocked only for hostile nations — the first official articulation of a selective blockade doctrine designed to fracture the coalition arrayed against Tehran.

Key takeaway

Selective passage weaponises transit rights as diplomatic currency while denying opponents a unified casus belli.

Iranian Foreign Minister Abbas Araghchi told Japan's Kyodo News: "the strait is closed only to ships belonging to our enemies, countries that attack us. For other countries, ships can pass through the strait." The audience was deliberate. Japan depends on Hormuz for more than 90% of its Middle Eastern crude imports and was granted passage the same week. Araghchi's statement codifies what the IRGC toll system had already established in practice — a selective blockade distinguishing between hostile and non-hostile nations.

Under international maritime law, all vessels hold transit passage rights through straits used for international navigation. A blanket Hormuz closure would unite maritime powers against Tehran and provide clear legal grounds for military enforcement. A selective closure divides them. Nations that joined the 22-country demand for reopening but pledged no warships NOW have a route to continued energy access — provided they keep their commitments rhetorical. Iran's doctrine rewards the gap between words and action that has characterised the international response. The seven-nation statement from 19 March produced no vessels; the expanded 22-nation version tripled the signatories and still produced none .

Araghchi's framing is consistent with Iran's broader negotiating posture. Days earlier, he told The National that Iran does not "believe in a ceasefire" and set conditions including removal of all US bases from the region and reparations . The selective blockade is not a de-escalation offer. Tehran maintains the military closure against US-aligned shipping while building bilateral dependencies with non-aligned states — dependencies that give each country an individual reason to resist joining any enforcement Coalition. For Washington, the structural problem is plain: every nation that secures bilateral passage from Iran has less incentive to challenge Iran's control of the strait.

Deep Analysis

In plain English

International law normally guarantees all ships the right to pass through major straits like Hormuz. Iran is claiming that, because it is at war, it can decide who gets through based on whether their country is an enemy. It has told Japan it may pass; US-allied countries cannot. This is legally contested — UNCLOS does not permit this discrimination — and it is deliberately designed to split potential opponents by giving some of them a reason not to enforce the rules.

Deep Analysis
Synthesis

By communicating the policy to a Japanese outlet rather than through formal diplomatic channels, Iran simultaneously sends three distinct messages: to Tokyo (passage is available), to non-aligned states (apply for your own exemption), and to the US (the closure has third-party legitimacy). The choice of venue is itself a diplomatic instrument.

Root Causes

Iran's selective blockade doctrine exploits a structural gap in UNCLOS enforcement: no automatic mechanism exists for enforcing transit passage rights, and enforcement depends entirely on state initiative and collective political will. A selective closure — which gives major powers a financial reason not to enforce — is specifically calibrated to paralyse that will.

Escalation

The public articulation of the doctrine locks Iran in. Araghchi's statement to Kyodo News — a deliberate choice of non-Western media venue — makes selective closure official Iranian policy. Iran cannot quietly reopen the strait to all shipping without a visible public concession, raising the political cost of de-escalation for Tehran regardless of military outcome.

What could happen next?
  • Precedent

    If Iran's selective blockade doctrine is tolerated, it establishes that belligerent states may discriminate among shipping by flag-state political alignment, rewriting the legal architecture of international straits passage.

    Long term · Assessed
  • Consequence

    Non-aligned states granted passage acquire a covert dependency on Tehran: passage can be revoked if their political alignment shifts, creating permanent ongoing Iranian leverage over their energy security.

    Medium term · Suggested
  • Risk

    The explicit public statement forecloses quiet diplomatic resolution — Iran cannot reopen the strait to all shipping without a public concession that signals domestic weakness.

Causes and effects
This Event
Hormuz open to friends, shut to enemies
By drawing an explicit distinction between hostile and non-hostile nations, Iran converts a military closure into a diplomatic instrument that penalises coalition membership and rewards strategic ambiguity.
Different Perspectives
G7 Leaders (ex-US)
G7 Leaders (ex-US)
Kananaskis ended without a joint communique for the first time in the body's history; Macron credited G7 pressure with speeding the ceasefire while Trump publicly denied the summit played any role. The split between US and European G7 partners over what the memorandum means for sanctions relief was the direct cause of the text failure.

London-based P&I mutual clubs declined to underwrite Hormuz crossings while the IRGC Strait Authority remained operational, making the passage commercially impassable regardless of the memorandum's terms. Shipping operators said they would wait weeks for on-water conditions to change before routing tankers through.

P&I mutual insurers declined to underwrite Hormuz crossings on 15-16 June while the IRGC's Strait Authority remained in operation, reducing actual transits to two vessels against a pre-war daily rate of 94. The corps' revenue-generating toll mechanism, created 5 May and collecting $1.5-2 million per VLCC in crypto, has not been stood down and cannot be dissolved by Ghalibaf's signature.

Netanyahu admitted he had not seen the memorandum's text but confirmed IDF forces would stay in southern Lebanon; Finance Minister Smotrich called for ten Beirut buildings destroyed per Hezbollah drone and National Security Minister Ben-Gvir said the agreement 'does not bind us in any way'. Israel signed nothing in Islamabad and is the central unresolved variable in the Lebanon clause.

Around 60 MPs signed a letter demanding Ghalibaf explain the memorandum; Paydari faction MP Sabeti said the deal violates the Supreme Leader's red lines, and MP Aboutorabi argued the document carries binding obligations 'that cannot be resolved by simply changing the name'. President Pezeshkian defended the negotiators against accusations of betrayal, confirming the fracture inside Iran's political class.

Vance signed on 15 June and said the memorandum was 'not conditioned on Israel withdrawing from Lebanon' while also saying it 'envisioned a ceasefire that covers both Iran and Lebanon'. The two formulations are incompatible and hand Iran's foreign minister a ready-made violation claim before Geneva.
