Background

The Strait of Hormuz

The strait carries oil equal to about a fifth of world petroleum liquids consumption and about a fifth of traded liquefied natural gas, and the pipelines around it hold only some 2.6 million barrels a day of spare capacity, which makes control of passage a lever long before the strait is fully closed.

The Strait of Hormuz

The Strait of Hormuz is the sea passage between Iran and Oman that connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest it is about 33 kilometres across. The US Energy Information Administration puts average oil flows through it at about 20 million barrels a day in 2024, roughly a fifth of world consumption of petroleum liquids. Around a fifth of globally traded liquefied natural gas took the same route that year, almost all of it Qatari.

Closing a chokepoint is not the only way to use one. The US-Israel war on Iran began on 28 February 2026, and Iran restricted passage to most ships from early March, in what Al Jazeera later called an effective closure. A memorandum of understanding with Washington reopened the waterway on 17 June. About 100 ships a day crossed before the war. In the first 18 days after the reopening, 513 did, on PortWatch figures reported by Al Jazeera. The question at sea is now whose permission a ship needs.

The exposure is not evenly spread. EIA tanker-tracking estimates for 2024 put Saudi Arabian crude and product flows through the strait at about 5.5 million barrels a day, Iraq's at 3.2 million, the United Arab Emirates' at 1.9 million and Kuwait's at 1.3 million. Of the crude and condensate, 84 percent went to Asian buyers, chiefly China, India, Japan and South Korea. Europe took about 0.7 million barrels a day of that crude. EIA notes that even a temporary blockage can raise shipping costs and lift world energy prices.

EIA names only Saudi Arabia and the UAE as having pipelines that move Gulf crude out without passing the strait. Saudi Aramco's East-West line carries 5 million barrels a day of capacity to Yanbu on the Red Sea, and a 1.8 million barrel line takes Emirati crude to Fujairah in the Gulf of Oman. Neither runs full, and EIA estimates only about 2.6 million barrels a day of it would be available in a disruption. Iran's Goreh-Jask line, about 300,000 barrels a day, has loaded nothing since September 2024.

The other way out is north. Ankara and Baghdad renewed the Kirkuk to Ceyhan pipeline deal on 1 August 2026, a one-year arrangement covering 750,000 barrels a day. The line's maximum is about 1.5 million; Turkish data put actual flows near 170,000. None of this settles the law. The Law of the Sea Convention says transit passage through such straits shall not be impeded and shall not be suspended. Iran wants recognised control of its side and a transit fee. Washington and many shipping lines say it must stay free.

The numbers

Oil flow through the strait, 2024
About 20 million barrels a day, the equivalent of about 20 percent of global petroleum liquids consumption, on EIA's estimate.
Share of global LNG trade, 2024
About 20 percent of traded liquefied natural gas transited the strait; Qatar shipped about 9.3 billion cubic feet a day that way, on EIA's estimate.
Spare capacity in the pipelines around the strait
EIA estimates about 2.6 million barrels a day of the Saudi and Emirati pipeline capacity could be available in a disruption, against about 20 million barrels a day that normally transits.
Transits after the reopening
513 ships transited between 18 June and 5 July 2026, an average of 28 a day, according to PortWatch data; before the war about 100 ships a day crossed.
Seafarers stranded in the Gulf
About 6,000, according to the International Maritime Organization, aboard ships unable to transit the strait safely.
Iraq's loss of exports
Iraqi oil exports collapsed by more than 80 percent in the weeks after the United States and Israel launched strikes on Iran in late February 2026, and monthly oil revenues fell from around $6bn to under $2bn.
The Kirkuk to Ceyhan pipeline
The renewed transit deal of 1 August 2026 covers 750,000 barrels a day. The line's maximum capacity is about 1.5 million barrels a day and it was carrying about 170,000, according to Turkish data.
What the law of the sea says
Article 38 of the Law of the Sea Convention gives all ships and aircraft a right of transit passage, which shall not be impeded, and article 44 states that there shall be no suspension of transit passage.

What the comparison shows

Where they agree

Nobody disputes the order of magnitude. The strait carries a fifth of world oil consumption and a fifth of LNG trade, and there is no substitute route on that scale: EIA puts spare pipeline capacity at about 2.6 million barrels a day against roughly 20 million that normally transits. Shipping analysts also agree that the damage starts well before a full closure. Diverted ships burn more fuel and spend longer at sea, which pushes operating costs up, and insurance and war-risk prices rise with them.

Where they split

Two questions split the parties. The first is whether passage through an international strait may be made conditional and priced: Iran says it intends to introduce transit fees when a 60-day transition period ends, while the United States and many shipping lines hold that passage should stay free. Oman has reportedly proposed a middle form, a joint regional mechanism with voluntary fees on the Strait of Malacca model. The second question is whether pipelines can replace the strait: Ankara and Baghdad present the Ceyhan route as a real alternative, while EIA's figures show that spare capacity around the strait is a fraction of the flows.

What nobody is saying

The mines and the insurance. Clearing mines is reported to fall to Iran, but nobody has said when it happens, who verifies that a lane is clear, or what follows if verification never comes. While that is open, the central section of the strait, where the seabed is believed to be most mined, stays largely unused. Nor has anyone set out what war-risk cover for a transit now costs. Premiums on politically exposed routes are said to have risen, but no figure for Hormuz has been published.

Who says what

Kazem Gharibabadi, Iran's deputy foreign minister for legal and international affairs

The strait cannot return to its pre-war state of free-flowing shipping. He rejects Oman's proposal for an equal division of the transit routes, saying it does not address Iran's security concerns, and proposes instead that Iran manage shipping on its own side while Muscat manages part but not all of the opposite lane. Iran, he says, will consider any action to keep control, including a resumption of the war.

Resul Serdar, Al Jazeera correspondent in Tehran

Describes the Omani compromise on the table: three separate lanes rather than a split of control, and an Iranian position more flexible behind the scenes than in its public statements.

The damage does not begin at closure. Making passage conditional on permission is enough to load costs and uncertainty onto shipping, and the danger is the precedent: if several states test the boundaries with selective enforcement, tolls or levies in international straits, outcomes are settled by bargaining power.

Cuts against the idea of a break with the old order. Using the sea to squeeze an adversary's economy is as old as naval warfare; what is new is the scale, the container volumes and the size of the world fleet, that is, how much a blockage now costs.

”Maritime action has always been an important aspect to weigh pressure on an enemy’s economy and military – there is nothing new there, but what has changed is the scale, the volume of containers, the size of the global fleet”Maritime action has always been an important aspect to weigh pressure on an enemy's economy and military, there is nothing new there, but what has changed is the scale, the volume of containers, the size of the global fleet

A route around the strait can be built. On 1 August 2026, after a meeting in Ankara with Iraq's oil minister, he announced that a transit arrangement for the Kirkuk to Ceyhan pipeline covering a daily capacity of 750,000 barrels had been implemented, while talks on a long-term agreement continue. The deal, he says, holds a more strategic position given developments in global oil markets.

An institutional counterweight to hopes placed in alternative routes. Most of the volumes that transit the strait have no other way out of the region, and spare capacity in the Saudi and Emirati pipelines runs to about 2.6 million barrels a day against roughly 20 million that normally transits.

”Most volumes that transit the strait have no alternative means of exiting the region, although there are some pipeline alternatives that can avoid the Strait of Hormuz.”Most volumes that transit the strait have no alternative means of exiting the region, although there are some pipeline alternatives that can avoid the Strait of Hormuz.
