Key takeaway

Hormuz reopening produced 4 ships and mine charts, not free passage

Donald Trump promised a 'COMPLETE, IMMEDIATE, and SAFE OPENING' of the Strait of Hormuz. On ceasefire Day 1, Kpler counted four bulk carriers transiting the strait. Zero crude tankers. Zero LNG carriers. More than 800 vessels remain stuck in the Persian Gulf 1.

The pre-war baseline was 135 transits per day. Iran's toll system, legislated in late March , had lifted traffic to 20 per day across 11 flag states by 5 April . The ceasefire cut that to four. Fewer ships crossed on Day 1 than on any day of the blockade.

ISNA and Tasnim, both linked to the IRGC, published maritime charts on 9 April showing a 'danger zone' over the main Traffic Separation Scheme lanes, dated from 28 February to 9 April 2. The charts direct all vessels to corridors near Larak Island under IRGC naval control 3. The implication: the main shipping lanes are mined. The mines, real or implied, force all traffic through Iran-controlled corridors.

Trump's two-week pause promised SAFE passage. The IRGC's charts promise the opposite: passage is SAFE only where Iran says it is.

Deep Analysis

In plain English

Trump said the strait was reopening. On Day 1, four cargo ships got through, zero oil tankers. Iran published charts showing the main shipping lanes are too dangerous and ships must use routes Iran controls. Eight hundred ships are stuck waiting. The reopening gives Iran more control, not less.

Deep Analysis
Root Causes

Iran's toll legislation in late March codified the blockade before any ceasefire. The mine charts are the physical enforcement layer of a legal framework already in place.

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.
Protection-and-Indemnity insurers

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.
IRGC Persian Gulf Strait Authority
IRGC Persian Gulf Strait Authority
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.
Israeli Cabinet

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.
US Vice President JD Vance

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.
