Key takeaway

Seven ships in 24 hours is a checkpoint, not a reopening.

Seven ships transited the Strait of Hormuz on ceasefire Day 3. None were oil tankers. 325 oil tankers and more than 600 vessels remain stranded inside the Persian Gulf. Iran's toll system had reached 20 transits per day before the ceasefire ; seven is a regression, not a recovery. The pre-war baseline of 135 per day illustrates the distance to normalisation.

Iran's inspection and ban regime transforms the strait from an international waterway into a customs border. Ships linked to Israel are excluded; tolls are reportedly payable in cryptocurrency. The IRGC (Islamic Revolutionary Guard Corps) mine charts published on 9 April direct all traffic through corridors near Larak Island under IRGC naval control. Oman formally refused the toll regime, citing international maritime treaty obligations, but Omani vessels still face the same inspection process.

ADNOC CEO Sultan Al Jaber put it plainly: "Passage is subject to permission, conditions and political leverage." Goldman Sachs issued revised scenarios: $82 per barrel base if Hormuz resumes this weekend, $100+ if closed another month, $120 severe. Every day without mine clearance normalises the toll regime that preceded the ceasefire .

Deep Analysis

In plain English

Before the war, about 135 ships passed through the Strait of Hormuz every day, carrying 20% of the world's oil. On Day 3 of the ceasefire that was supposed to reopen it, only seven ships passed and none were oil tankers. 325 tankers are sitting stuck inside the Gulf waiting. Iran is charging fees, banning some ships, and controlling who gets through. The UN tried to force the strait open; Russia and China blocked it.

Deep Analysis
Root Causes

Iran's closure of Hormuz reflects a shift from opportunistic disruption to structural leverage doctrine. The toll system represents a permanent claim to sovereign authority over an internationally recognised strait — the same claim it made unsuccessfully in the 1980s. The ceasefire has preserved the toll regime rather than ending it, which is Iran's primary economic gain from the war regardless of nuclear outcome.

China and Russia's UNSC veto removes multilateral enforcement. Without that mechanism, Hormuz reopening requires either a bilateral US-Iran deal that explicitly addresses the toll regime, or unilateral US naval action. The Trump administration has so far declined both .

What could happen next?
  • Consequence

    Every day without mine clearance normalises Iranian toll authority over an internationally recognised strait, making restoration of UNCLOS freedom of navigation progressively harder to claim without confrontation.

    Short term · Assessed
  • Risk

    GL-U expiry on 19 April would recriminalise 325 stranded tankers' cargo before the ceasefire even ends, forcing operators to choose between legal jeopardy and abandoning cargo.

    Immediate · Assessed
  • Consequence

    China's tankers already transit under the toll regime; its UNSC veto locks in a competitive advantage over Japanese, South Korean, and European shippers for as long as the regime persists.

Causes and effects
Caused by
Iran publishes mine charts converting Hormuz reopening into IRGC corridor
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.
Occurred 9 Apr 2026
Read story →
Hormuz toll system carried 20 transits per day before ceasefire
The 20/day transit level reached by 5 April (ID:2119) under the toll regime has been cut further by ceasefire Day 3 conditions — the ceasefire has reduced traffic rather than increased it.

Brent rebounds as Goldman prices ceasefire risk
Oil markets repriced on ceasefire announcement (ID:2124); Goldman's $82-$120 Brent scenarios on Day 3 represent the market's updated pricing of persistent Hormuz restriction.

This Event
Seven Ships Cross Hormuz, No Oil Tankers
The ceasefire has reduced Hormuz transits rather than raised them; Iran's de facto customs authority over the strait is consolidating daily.

Monitors documented 30 women held on capital moharebeh charges in a basement prison ward, Benyamin Naqdi's death sentence with a forced-confession broadcast, and 39 political executions since February. Iran's security courts have processed protest cases at uninterrupted wartime tempo regardless of the diplomatic track.

Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent fell 19%, maintaining a structural divergence from futures pricing. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism, before de-listing the strait.
Oman (Sultan Haitham's government)

Muscat issued a mine alert in its own territorial waters while denying any Hormuz toll plan after US Treasury threatened sanctions. A suspected mine in Omani waters on the same weekend as US financial pressure forces Muscat to demonstrate sovereignty without appearing to choose sides.

Beijing sent scholars rather than its defence minister to Shangri-La for the second year running and addressed Taiwan and multilateralism without mentioning Iran. China maintains its bilateral energy corridor protection with Tehran while refusing the diplomatic exposure of a public position at multilateral forums.

The SNSC framed the unsigned MOU as a 10-point Iranian victory with enrichment already recognised, and the foreign ministry rejected Trump's nuclear conditions within hours. Tehran treats each unsigned day as validation that Iran has retained its stockpile without surrendering it.

Trump posted three non-negotiable public conditions while CENTCOM disabled a commercial ship and Hegseth threatened resumed strikes from Singapore. The administration treats the unsigned MOU as leverage to extract maximum Iranian concessions before any ceasefire instrument is committed to paper.
