Washington has set an exchange rate for the Strait of Hormuz: three Iranian tankers for every two missiles
US Central Command struck three Iranian crude carriers on 5 September and published the arithmetic behind it. What began on 1 September as a “tanker for tanker” practice is now a declared policy of fleet destruction, with the target set extended by the Secretary of War as far as the Indo-Pacific Command area. The trackers watching the strait cannot agree on how much traffic is left, and the countries paying for the closure are mostly not Iran.
CENTCOM said its forces struck the vessels after the IRGC fired two ballistic missiles at two US Navy warships, and that “a U.S. aircraft carrier and guided-missile destroyer successfully evaded multiple unprovoked Iranian attacks.” It named the ships: the M/T Downy off Kharg Island and the M/T Stark 1 near Jask, both “permanently disabled,” and the M/T Kylo, also known as the Noxen, “completely destroyed” in the Gulf of Oman. The statement carried its own tariff: “If you shoot at two of our ships, we will impose an even higher economic cost — taking out three of yours.” Pete Hegseth, the US Secretary of War, has described Iran’s tanker fleet as “defenseless” and said American aircraft, warships and submarines could strike Iranian tankers across both the CENTCOM and Indo-Pacific Command areas — wording that places crude bound for Chinese buyers inside the declared target set. Iran’s foreign ministry called the strikes part of “the naval blockade and economic warfare imposed on the Islamic Republic,” a violation of Article 2(4) of the UN Charter and a war crime. The IRGC claimed it had damaged the carrier and destroyer and forced both from the engagement area; it has produced no evidence, and Army Recognition, a naval trade publication, notes CENTCOM has identified neither ship, nor the number or type of missiles fired.
No one can say with confidence how much shipping is left to price. Kpler counted six vessels through the strait on Wednesday, eleven on Tuesday and five on Monday, a ten-day average of thirteen a day — against President Trump’s claim that the United States is helping roughly thirty ships across daily. Lloyd’s List Intelligence recorded 102 transits last week against 126 the week before, and puts the pre-war figure at 130 or more a day. The unattributed straits.live tracker gives a pre-war normal of about 85 a day, which means the denominator itself is contested before anyone argues about the numerator. CBS reports that significant volumes still move because operators are running a shuttle trade down a southern route, and Energy Secretary Chris Wright has said Washington will maintain the blockade while supporting safe passage for commercial vessels — an admission that the cordon is deliberately porous. Windward’s operations centre logged one 228-metre Marshall Islands-flagged tanker u-turning off Kumzar at 02:31 UTC on 6 September, reversing into the Gulf, then turning back toward the outbound crossing twelve hours later. The vessel is unnamed in the public record.
The costs are being collected some distance from Tehran. Brent stood at $97.29 on 7 September, up 10.91 per cent on the month and 47.36 per cent on the year, though still well below its 52-week high of $126.41; the US Strategic Petroleum Reserve has fallen below 290 million barrels, its lowest since 1982. Egypt’s Suez Canal took $1.26bn in the second quarter against $1.12bn in the first, with tankers making up 1,526 of 3,580 transits — a recovery the aggregator Rio Times attributes not to a safer Red Sea but to the Hormuz closure lengthening voyages, a reading that rests on a single outlet and has not been checked against SCA or CAPMAS bulletins. Iraq, whose government spokesman now describes two million barrels a day as normal, has been pushing volumes north to Ceyhan since June precisely because the strait is shut. Kuwait’s defence ministry has counted 67 servicemembers wounded and its interior ministry two border guards killed. The blockade is a pricing mechanism, and the bill is circulating.
Assessment: Treat the battle-damage claims on both sides as unresolved. CENTCOM released tanker footage and no imagery of the missiles it says it evaded; the IRGC released a claim and nothing at all. That symmetry has not survived into the coverage, which is a separate matter and sits on the Western Media Watch desk today. On the traffic numbers, be careful whose baseline you adopt: UANI, which relays the JMIC counts, campaigns against the Iranian government, straits.live has no named editor, and Trading Economics prices are CFD-tracked rather than exchange settlement. The more useful point is structural. By publishing an exchange rate, Washington has converted an interdiction campaign into a posted tariff, which is legible, repeatable and therefore easy for Tehran to plan against — Solace Global’s assessment is that the deadlock costs Iran more and so pushes it toward escalation, not away. The Indo-Pacific reference is the untested clause. Nobody has asked what happens the first time a cargo bound for a Chinese refinery is destroyed east of Hormuz.
