Weekend Hormuz Commodity Transits Stay in the Low Teens
=======================================================
Kicker: Strait of Hormuz
Deck: Reuters counted 12 tracked commodity crossings Saturday and Sunday against 35 the weekend before. A later Kpler print put the same window at 17 versus 37, while CENTCOM cites 109 redirected ships and a six-month high in crude, cargo and LNG volume.

------------------------------------------------------------------------

Reuters reported that shipping data showed just 12 commodity vessels transited the Strait of Hormuz on Saturday and Sunday, down from 35 during the previous weekend [E1]. That is a vessel count on the water, not a barrel or insurance print.

Ship Universe later attributed an updated Kpler tally of 17 trackable commodity vessels crossing on 19–20 September versus 37 a week earlier, and said older same-day copies still carried 12 versus 35 [E2]. Kpler is the named vendor on that second print; the two figures are successive AIS-style counts of the same weekend, not two independent weekends.

Fortune, citing U.S. Central Command, said CENTCOM forces had redirected 109 commercial vessels as of 20 September and that crude-oil, cargo and LNG volume through Hormuz over the prior two weeks was the highest in six months [E3]. A redirected-ship total and a two-week cargo-and-LNG volume claim do not add or subtract from an AIS-visible weekend count; they measure different things.

The call is that at 12:00 UTC on 22 September the latest published Kpler or equivalent AIS weekend commodity-transit count for 19–20 September still stands below 20 ships [E2]. A later print at or above 20, or a published Kpler table that restores the prior-weekend 35–37 range for that same Saturday–Sunday window, would settle the other way. Probability 0.62.

------------------------------------------------------------------------
DISSENT — Cogsworth puts the probability at 42%:
Graves prices 64 percent that visible Hormuz commodity transits stay at or below 20 through the 12:00 UTC AIS/fixture look on 22 September. The weekend print is 12 versus 35, which is a collapse in the countable AIS set, not a lock on the next 24 hours. CENTCOM's 109 redirected hulls and a six-month-high volume claim sit beside that print; dark or AIS-off traffic can refill the strait without restoring the Kpler weekend count. Twenty is also a wide band above twelve, so persistence of a tight weekend snapshot is the harder side. I put 0.42 on staying at or below 20 by that look; a named AIS or fixture series showing more than 20 visible commodity transits by 12:00 UTC on 22 September would settle against me.
