The headline number is 20% on all cargo shipped through the Strait of Hormuz, framed as reimbursement for American protection. The legal objections write themselves and have already been written. The more interesting question is who the levy actually lands on, and the answer is not Iran.

It lands on Qatar.

The Only Cargo That Cannot Escape

Around 93% of Qatar’s LNG exports and 96% of the UAE’s leave through the Strait of Hormuz. There is no alternative route. Crude has partial escapes — Saudi Arabia and the UAE hold somewhere between 3.5 and 5.5 million barrels a day of pipeline bypass capacity, enough to matter at the margin. Gas has none. You cannot put liquefied natural gas on a truck, and no pipeline exists that can move Ras Laffan’s output to a non-Gulf loading point at any volume worth discussing. Qatari LNG goes through the strait or it does not go.

A bulk carrier was struck by an unknown projectile on Sunday morning approximately 23 nautical miles northeast of Doha, igniting a fire aboard the vessel, the United Kingdom Maritime Trade Operations Centre confirmed. The fire was subsequently extinguished. No casualties or environmental damage were reported.

The attack is the latest in a sustained campaign of maritime strikes across the Persian Gulf following the shaky ceasefire that halted direct US-Iran combat operations. No party has formally claimed responsibility, but the strike follows explicit warnings issued hours earlier by Brigadier General Amir Akraminia, spokesman for the Iranian Army, who stated that countries enforcing sanctions against Iran “will certainly face problems passing through the Strait of Hormuz.”

Before February 2022, European energy security analysis treated the Persian Gulf as a significant but secondary concern. The primary vulnerabilities ran through Ukrainian pipeline corridors and Russian supply decisions. Hormuz was a risk to Asian energy markets, to oil prices globally, and to a residual flow of LNG from Qatar to a handful of European regasification terminals that had been built for flexibility rather than baseload supply. The invasion of Ukraine changed this with a speed that European energy planners had not fully modeled. By the end of 2022, Europe was competing in global LNG markets for volumes that included substantial Qatari supply, and its exposure to events in the Persian Gulf had become structurally different from anything its policy frameworks had anticipated.

Beneath the shallow waters of the Gulf, shared between Qatar and Iran, lies the North Field — the largest single natural gas reservoir on earth. The Qatari portion is developed. The Iranian portion, called South Pars, is partially developed and severely constrained by sanctions and investment restrictions. What happens to the gas that Qatar extracts from its side of the reservoir determines energy supply conditions for electricity consumers in Japan, industrial gas buyers in South Korea, and power generators across Europe. All of it moves through Hormuz.
