On 22 June CENTCOM, the US military command covering the Gulf, counted 55 merchant ships transiting the Strait of Hormuz while Kpler, the Paris-based cargo tracker, logged only 121. A 43-ship gap between a military count and a commercial tracker is too large to be measurement error. Kpler reads transits from the AIS transponders ships are meant to broadcast; CENTCOM counts hulls it can see. Supply-chain analyst Behrouz Bakhtiari attributed the gap to AIS-dark vessels routing along the Omani shoreline, transiting independently of both the framework and IRGC enforcement2.
That is a third operating mode for the strait, neither open nor closed, that no prior update has named. It sits underneath the headline status the screens chase: the IRGC says shut, CENTCOM counts movement, and a dark corridor runs between the two. About 515 vessels stayed anchored region-wide on 22 June, most of them waiting for the insured route rather than the strait itself, while low-volume dark transits continue3.
For the freight desk this complicates the read on the forward curve. If barrels move dark, the insured and flagged spot premium the TD3C spot rate captures overstates the real supply loss, because the cargo crossing the Omani shore pays no war-risk freight and shows up in no benchmark. No price instrument captures a compliance-blind corridor cleanly, so it sits underneath the headline transit count as a structural variable. The closure politics belong to Iran-conflict-2026; the flow implication, that the visible count and the true volume have come apart, is the trade here.
