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.

Causes and effects
This Event
Iran publishes mine charts converting Hormuz reopening into IRGC corridor
The mine charts convert a wartime blockade into a permanent navigational authority, making the ceasefire's reopening promise a guided tour through Iran's customs architecture.

Different Perspectives
Oil markets and Lloyd's of London
Oil markets and Lloyd's of London
Brent fell to $89.25 on ceasefire probability, not new barrels, with traders voting for Trump's deed over Tehran's denial. Lloyd's has not repriced Hormuz war-risk cover because its trigger requires a UN Security Council resolution or government certification, so tanker insurance costs remain elevated regardless of the spot move.
Pakistan and Qatar mediators
Pakistan and Qatar mediators
Pakistan's Mohsin Naqvi was in Tehran for his second visit in under a week, using the Pakistan-Qatar channel that delivered April's ceasefire after an identical public-denial cycle. The channel carries both civilian and military buy-in from Islamabad, the only configuration Iran's split command cannot dismiss as a partial signal.
India
India
India summoned the US Deputy Chief of Mission after three Indian sailors were killed aboard MT Settebello, the first formal grievance from a major non-belligerent directed at US enforcement. Indian seafarers supply roughly 12 per cent of the global maritime workforce; their presence on third-flag Gulf tankers is structurally inevitable regardless of bilateral diplomacy.
Islamic Revolutionary Guard Corps (IRGC)
Islamic Revolutionary Guard Corps (IRGC)
The IRGC declared Hormuz closed on 11 June while civilian negotiators were on the same mediation channel, then issued no public comment on the MoU framework. Its silence on the framework, rather than any foreign ministry statement, is the operative approval signal; the corps' unilateral Hormuz closure shows it did not treat the diplomatic track as binding on its operations.
Iran foreign ministry (Baghaei)
Iran foreign ministry (Baghaei)
Esmail Baghaei told IRNA that reports of a finalised deal were 'merely speculation' and that Iran had 'not yet made a final decision'. The denial is structurally identical to Iranian foreign ministry statements during the April ceasefire talks, which produced a binding text within 48 hours of the same language.
Trump administration / CENTCOM
Trump administration / CENTCOM
Trump cancelled the third strike day and called the MoU 'very strong' and almost ready to sign, while CENTCOM kept tanker enforcement running in the same 24-hour window. The administration is simultaneously withdrawing the military pressure it claims drove the deal and sustaining the enforcement campaign it is trying to trade away.
