Iran has begun charging for passage through the Strait of Hormuz by political alignment. China, named a friendly country, is offered a discount. Everyone outside the friendly list pays full mandatory fees and risks attack for using any route Iran does not authorize. The world's most important oil chokepoint is turning into a sorting machine, and the terms of transit now depend on where a flag stands with Tehran.


On July 4, Iran's ambassador to China said Beijing would receive "special considerations" on the cost of transit through the Strait of Hormuz, because China is a friendly country. The phrasing is deliberately dull. What it describes is a decision to price a waterway by friendship.

Iran's foreign minister had already published the guest list. China, Russia, India, Iraq and Pakistan are the friendly states whose vessels may pass. The toll works like a schedule keyed to each country's standing with Tehran. Friendly flags get a rate. Everyone else gets a mandatory fee and the standing threat that runs underneath all of it.

That threat is no longer theoretical. Between July 2 and 3, at least eight vessels tried to leave the strait along the Omani coast, using the legal alternative route, and turned back. They resumed transit through Iran's own traffic separation scheme within a day, almost certainly after being threatened. When the UK and France announced they would work with Oman to keep that alternative open, Iran's deputy foreign minister warned both governments against any military activity in the strait. The instruction is consistent. Use the route Iran designates, or do not sail.

There is a mundane reading of the discount, and it deserves stating. A monopolist charges its largest and most mobile customer less, charges its captive customers more and calls the arithmetic strategy. China has other ways to get oil. Western-linked traffic has fewer. Price discrimination is ordinary commerce, and a sanctioned economy protecting the handful of buyers it cannot afford to lose is doing something very old. That reading holds. It also does not touch the part that matters.

Whatever the motive, the structure is now visible. Transit through a chokepoint that carries over a fifth of the world's oil and gas is being sorted into tiers by political alignment, and the West is sitting on the wrong one. A flag's cost of passage has become a readout of its relationship with Iran.

Keep the strait's real weight in view. By total trade value Hormuz is smaller than the Malacca and Taiwan Straits, each of which carries around a fifth of all seaborne trade. Hormuz still moves over a fifth of the world's oil and liquefied natural gas. Its leverage comes from control. One state can physically close Hormuz, and has chosen to. The volume flowing through it is almost beside the point.

The model is already travelling. After Iran started tolling Hormuz, Indonesian officials floated tolling the Malacca Strait, then backed off under the rule that international straits must stay open. The proposal surfacing at all is the signal. A second coastal state looked at a chokepoint it borders and reasoned exactly the way Tehran did, out loud, within months.

Each friendly transit at a discount does one quiet thing. It records a country accepting that Iran sets the price. The tolls may or may not ever be collected in full. The tiering is doing its work regardless, sorting the world's shipping into those who pay Iran's rate willingly and those made to.
