Ship-tracking data puts Hormuz traffic at a fraction of the volume Washington claims to be escorting

Al Jazeera, citing the commodity-tracking firm Kpler, reported on 3 September that just six vessels crossed the Strait of Hormuz on Wednesday, 11 on Tuesday and five on Monday, putting the ten-day average at 13 vessels a day — against the roughly 30 daily transits the US president says American forces are helping through. The independent tracker straits.live, updated on 5 September, describes the strait as effectively closed to commercial shipping, logging six transits on 30 August against a pre-war baseline near 85 a day. The Joint Maritime Information Center’s figures, republished by the advocacy group United Against Nuclear Iran — attribute both — record 877 transits between 18 June and 2 September, and 1,490 since the war began, with a single-day high of 54 on 24 June. UANI also reports that as of 1 September US forces had “redirected 84 commercial vessels trying to run the blockade, disabled 3 that didn’t comply, and boarded 2 to ensure total compliance”.

The pricing follows the traffic. Reuters reported that Brent futures rose $4.16, or 4.6 percent, to settle at $94.65 a barrel on 1 September, with WTI up $4.46 to $90.22 — the highest closes since 24 and 23 July respectively. straits.live carried Brent at $95.83 on Friday. The Windward Maritime Intelligence Operations Center assessed on 4 September that US forces had struck the engine rooms of two Iranian government tankers at anchor on 1 September in direct retaliation for the attacks on the Sidr and the Senegal Prosperity — its judgement, not a finding, but one that establishes the precedent for the 5 September strikes. NPR describes a six-month war that has spiked oil prices and roiled the global economy. Trump, speaking on Friday, called the war “small potatoes” for the United States, a day after Vice President JD Vance declined to describe the conflict as a war at all.

Assessment: The gap between 13 and 30 is not a rounding error, and it is the most useful single indicator on this desk. An escort claim is a claim about control; transit counts are the audit. Note who publishes what: Kpler and the JMIC are counting hulls, UANI is an advocacy organisation republishing them, and straits.live is an aggregator whose $2bn war-risk figure needs an insurer source before anyone quotes it. The “small potatoes” framing and the Labor Day fuel-price coverage sitting in the same live blogs describe the actual constraint on Washington — not Iranian missiles, but the price of a barrel through an American autumn.
