Key takeaway

Hormuz is delivering fewer transits under ceasefire than under Iran's own toll regime.

Kpler recorded 5 vessel transits through the Strait of Hormuz on 9 April and 7 on 10 April, against a pre-war baseline of 120 to 140 daily ¹. The ceasefire is delivering fewer movements than the 20 transits per day Iran's own toll regime was carrying on 5 April . More than 600 vessels remain stranded inside the Gulf, including 325 oil tankers.

Sultan Al Jaber, chief executive of ADNOC (Abu Dhabi National Oil Company), told reporters on Friday that "the strait of Hormuz is not open. Access is being restricted, conditioned and controlled" ². Ana Subasic, a Kpler analyst, projects a ceiling of 10 to 15 transits per day even if the ceasefire fully holds.

That ceiling is roughly one-tenth of the pre-war baseline and half of Iran's own toll volume last week. It implies structurally tight oil throughput regardless of Brent's headline price , and no single-day breakthrough is likely to restore pre-war flow. The Gulf is moving at a trickle because the physical problem in the water is larger than the political problem in the hotel in Islamabad.

Deep Analysis

In plain English

Before the war, 120 to 140 ships passed through the Strait of Hormuz every day carrying oil from Gulf states to the rest of the world. In the three days since the ceasefire, that number has fallen to five or seven — not much more than zero. The ceasefire stopped the bombing, but it did not clear the sea mines, lift the shipping insurance bans, or dissolve the Iranian inspection system. A political peace agreement does not automatically move oil.

Deep Analysis

Root Causes

The trickle is not a ceasefire failure in the usual sense. It reflects three compounding physical constraints that the diplomatic process cannot resolve: uncharted Iranian mines making navigation hazardous, the IRGC corridor system restricting passage to specific channels near Larak Island, and the withdrawal of war-risk insurance coverage from standard commercial operators.

The UN Security Council's 11-2 vote for a Hormuz reopening resolution was vetoed by Russia and China — both of whom benefit from the toll architecture their own tankers already use. The multilateral route to maritime normalisation is therefore closed, leaving only bilateral US-Iran negotiation or unilateral force, neither of which resolves the physical mine problem.

What could happen next?

Consequence
Brent crude will remain structurally elevated at 40-60% above pre-war levels until mine clearance and insurance normalisation occur, regardless of which diplomatic outcome Islamabad produces.
Risk
GL-U expiry on 19 April would simultaneously criminalise the 325 stranded tankers' cargo under US sanctions while they remain physically unable to move, creating a compound maritime-legal crisis.

Primary parallel: During the 1984 Tanker War phase of the Iran-Iraq War, Iranian mining and attacks on Gulf shipping reduced commercial transit by roughly 25% before the US Navy began Operation Earnest Will escort missions in 1987. Full insurance-market normalisation took 18 months after the 1988 ceasefire. The structural dynamic — physical threat persisting after political agreement — is directly analogous.

Counter-parallel: After the 1990-91 Gulf War, Kuwait's offshore oil export infrastructure recovered within six months of hostilities ending because US and UK mine-clearance teams were pre-deployed and the field was shallower, more confined, and better-charted. The Hormuz Strait presents a harder clearance problem at greater depth and with no admitted mine charts from the laying force.

The 325 oil tankers stranded inside the Gulf represent approximately 650 to 700 million barrels of combined capacity at typical VLCC loads — roughly seven days of global oil demand sitting immobile. Each additional day of immobility adds demurrage costs that insurers ultimately price into war-risk premiums, compounding the blockage.

The structural mismatch is stark: pre-war Hormuz carried 20 million barrels per day. At 7 transits per day with standard VLCC cargo, throughput is under 14 million barrels per day less than pre-war baseline — roughly equivalent to removing Saudi Arabia's entire daily export volume from global supply. GL-U expiry on 19 April would add a sanctions layer on top of the physical constraint, making the stranded tankers legally as well as operationally immobile.

Consensus view: Ana Subasic at Kpler and Goldman Sachs (Q2 forecast at $90 with $100+ flagged if Hormuz stays at current throughput) both assess that even under a best-case ceasefire scenario, Hormuz cannot return to pre-war throughput until the mine threat is eliminated and war-risk insurance is lifted — two conditions that no current diplomatic process addresses .

Counter-view: The Carnegie Middle East Center notes that the shadow-fleet architecture built during the Iran-sanctions period before the war can absorb a fraction of stranded cargo: vessels that transited under IRGC toll conditions remain technically capable of transiting again, and Chinese and Russian tankers have shown willingness to operate at elevated insurance cost.

Key tension: Whether the 10 to 15 daily transit ceiling is a temporary operational trough or the new structural normal for Hormuz throughput, with insurance markets holding the deciding vote.

Causes and effects

Caused by

Hormuz toll system carried 20 transits per day before ceasefire

The 5 and 7 vessel transit counts on 9-10 April are far below the 20 transits per day the toll regime was producing on 5 April, showing the ceasefire has produced fewer transits than the blockade.

This Event

Hormuz trickle: five then seven vessels

The ceasefire has so far produced fewer transits than the blockade it was supposed to end, implying insurance and oil markets will hold war-risk pricing indefinitely.

Led to

IRGC declares Hormuz will never reopen

Kpler's Hormuz transit data (ID:2205) underpins the IRGC's effective blockade and the IRGC's claim the strait 'will never return to previous status.'

Different Perspectives

China

Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.

Israel

IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.

Bahrain

The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.

Qatar

Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.

Kuwait

Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.

United States

Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
