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.
Led to
Seven Ships Cross Hormuz, No Oil Tankers
IRGC mine charts published 9 April (ID:2121) forced all ships into IRGC-controlled Larak Island corridors, directly suppressing Day 3 transit count to seven ships with zero oil tankers.

Different Perspectives
US money managers (CFTC-tracked)
US money managers (CFTC-tracked)
US money managers had trimmed WTI net long positioning into July's rally, doubting the Hormuz premium would hold without freight or war-risk confirmation, and the crude stock build reported for the week to 17 July gives that scepticism a fundamentals basis. The 25 July CFTC data will show whether Brent's move above $100 changed their calculus.
Asian distillate buyers (Singapore)
Asian distillate buyers (Singapore)
Singapore's distillate holders kept retaining middle-distillate barrels as the East-West arbitrage window narrowed further this week, a pattern that sharpened as Fujairah light distillates hit a record low. Cargoes are being held rather than released west into the tightening Mediterranean market.
Bulgaria
Bulgaria
Bulgaria secured the removal of Lukoil founder Vagit Alekperov and Patriarch Kirill from the 21st package, with President Rumen Radev calling a personal listing 'shooting ourselves in the foot'. Sofia is protecting its position in Lukoil's EUR 3bn compensation claim over the 2023 Neftohim Burgas nationalisation.
Russia
Russia
Russia loses the roughly $14 a barrel of legal headroom the price-cap formula would have released toward $58, even as Urals continues trading below Moscow's $59 budget floor. The shadow-fleet insurance workaround that lets sanctioned crude clear above $44 in practice remains untouched by the freeze itself.
European Union
European Union
The EU adopted its 21st sanctions package on 23 July, freezing the $44 Russia oil cap for 12 months rather than letting the formula drift it toward $58, and listed shadow-fleet support vessels for the first time. The package cleared only after three failed Coreper votes.

Marine war-risk underwriters (Lloyd's-linked syndicates)
War-risk syndicates lifted southern Red Sea hull premiums 150% to about 0.75% of hull value after the 20 July blockade declaration, still a seventh of the roughly 5% Hormuz band. Underwriters reset on realised loss, not declared threat, so the 23 July Encelia and Layla strikes set up the next re-mark.
