Key takeaway

Iran has declared the strait's pre-war status permanently over, not conditionally suspended.

The IRGC (Islamic Revolutionary Guard Corps) stated that mines remain in the Strait of Hormuz and that the waterway "will never return to its previous status." Commercial traffic sits at roughly 8.0% of the pre-war daily baseline: Kpler data shows 5 to 11 transits per day against a pre-war norm of 120 to 140 .

More than 600 vessels, including 325 oil tankers, remain stranded inside the Gulf, according to Lloyd's List Intelligence. Iran is vetting each vessel individually before granting passage, a process that analysts expect will cap throughput at 10 to 15 ships per day even if the vetting posture loosens. At that rate, clearing the backlog alone would take weeks.

The IRGC's language is worth parsing carefully. "Will never return" is not a negotiating position; it is a declaration of a new permanent status. It aligns with Iran's Islamabad proposal, which sought to impose fees on every vessel passing through the strait, reportedly $1 to $2 million per ship. If formalised, that would create a precedent for every maritime chokepoint globally.

For consumers, the blockade's persistence translates directly. Roughly 20 million barrels per day of oil that normally passes through Hormuz is absent from global supply. Oxford Economics projects that disruption will cut world GDP growth by 1.2 percentage points in 2026. That cost is accumulating daily while the strait stays effectively closed.

Deep Analysis

In plain English

Before this war, about 120 ships a day passed through the Strait of Hormuz carrying oil to Asia, Europe, and North America. Now fewer than 10 a day are getting through, and Iran is choosing which ones. The IRGC, Iran's elite military force, has now said publicly that the strait 'will never return to its previous status'. That is a statement that even after any deal is done, they intend to keep some form of control over who passes through. There are also naval mines still in the water that Iran says it placed there, and some of which Iran itself cannot locate. Those mines are a physical danger to any ship trying to transit, separate from the political question of permission.

Deep Analysis

Root Causes

Iran's 'will never return' framing reflects a strategic objective that predates the current conflict: control over Hormuz transit has been an IRGC doctrine since the 1980s Tanker War, when the corps first demonstrated it could enforce selective passage. The ceasefire did not alter that doctrine; it merely paused its full implementation.

The $1-2 million per-vessel toll demand, reportedly already being charged informally, represents an attempt to monetise the closure into a permanent revenue stream. If institutionalised, Hormuz tolls would provide the IRGC with an independent hard-currency revenue source that bypasses sanctions on oil exports.

What could happen next?

Precedent
If the IRGC's 'will never return' declaration stands unchallenged, it establishes the first successful post-1945 precedent for a coastal state permanently altering the legal status of an international strait, with implications for the Bab el-Mandeb, Malacca, and Taiwan Strait.
Long term · Medium
Consequence
The 325 stranded oil tankers represent approximately 16 days of total OECD oil reserve draw-down at current consumption rates; the longer they remain trapped, the greater the probability of strategic reserve releases that would cap but not eliminate the price spike.
Short term · High
Risk
Iran's acknowledged inability to locate all its own mine placements means the risk of an unintentional mine detonation by a commercial vessel is non-trivial and independent of any political or diplomatic development.
Immediate · High

Primary parallel: The 1956 Suez Crisis saw Egypt nationalise and physically block a major global waterway; the precedent it set is that a coastal state can in practice control an international waterway if it is willing to bear the military and diplomatic costs. Egypt eventually reopened Suez under a face-saving formula. Iran's position is structurally analogous.

Counter-parallel: The 1979-1989 Nicaragua v. United States ICJ case ruled that mining international waters without notice violated customary international law, but the US simply withdrew from ICJ compulsory jurisdiction rather than comply. Iran has no ICJ compulsory jurisdiction either, which means the legal framework provides zero enforcement.

The Kpler baseline of 120-140 daily transits carrying roughly 20 million barrels of oil represents approximately $1.9 billion in daily oil value at $95/barrel. At $1-2 million per vessel, a toll regime on even 50 transits daily would generate $18-37 billion annually for whoever controls collection.

For shipping insurers, the IRGC's mines declaration has triggered 'additional war risk' premiums that Lloyd's of London war risk market sources have estimated at 0.5-1.5% of vessel hull value per voyage, adding $1-5 million per Panamax tanker transit on top of the proposed toll. Those costs are ultimately passed through to consumers via higher oil prices.

Consensus view: Just Security's analysis of UNCLOS customary law and Kpler's shipping data both point to the same conclusion: the IRGC's 'will never return' declaration transforms Hormuz from a temporary military closure into a claimed permanent sovereign chokepoint, which has no precedent in post-1945 international maritime law and no enforcement mechanism short of military action.

Counter-view: Iranian maritime law scholar Nasser Katouzian's school of interpretation, reflected in IRGC statements, holds that Iran's 12-nautical-mile territorial sea extends to both shores of the strait and that transit passage rights under UNCLOS are contingent on state security, not absolute. Under this reading, rejected by Western legal scholars but operationally asserted by Iran, the current posture is Iran's legal right.

Key tension: No international court has jurisdiction to compel Iran's compliance with UNCLOS transit passage rules; the UN Security Council route is blocked by Russia and China's veto . The only enforcement available is military, which is precisely what the ceasefire is meant to prevent.

Different Perspectives

Sanctions compliance officer reviewing a Lukoil International GmbH bid

OFAC's amended FAQ 1224 gives a compliance desk its first published standard: full severance from Lukoil and a US-jurisdiction blocked account for sale proceeds. The conditions name neither ISAB nor Italy, so a Priolo Gargallo-linked bid answers a different question than a Neftochim Burgas or Petrotel Ploiesti one.

Managed-money funds on Brent Last Day

CFTC data for the week to 21 July showed managed money flipping 74,400 contracts to a net long of 15,665 against 1,410 short on the Brent Last Day contract, code 06765T. A fund that held that short through July has now covered it, and the spent short base raises the bar for the next leg higher.

Saudi crude exporters

Saudi-linked tanker transits through Bab el-Mandeb fell to about 7.5 a day after the 24 July underwriting withdrawal, pushing more barrels onto the longer route round the Cape or through the Yanbu terminal. Every diverted barrel ties up a ship for longer, and a fleet that turns slower charges more.

Tanker owners on the Bab el-Mandeb route

Lloyd's-market syndicates withdrew war-risk cover from Saudi-linked hulls on 24 July, leaving owners of that class of vessel to sail Bab el-Mandeb uninsured or not at all. Tanker transits on the route fell to roughly 7.5 a day, and cover, once withdrawn, does not return on a shipowner's timetable.

Eni

Eni's board approved second-quarter results on 29 July, swinging refining EBIT to a EUR0.08bn profit from a year-earlier loss even as group profit doubled, and named Red Sea freight cost as a cap on that improvement. A refiner absorbing higher shipping costs on Saudi-linked crude while its numbers improve treats the freight line as a drag, not a crisis.

Asian buyers (India, Japan, China, South Korea)

Asian refiners are absorbing 62% of Yanbu's 3.75m b/d flow, the bulk of Saudi Arabia's rerouted crude now clearing east rather than into the Atlantic basin. That destination split leaves Asian buyers more exposed to any single Yanbu-specific disruption than under the kingdom's normal multi-terminal export pattern.
