Last week the count went up; this week it meets its first enforcement mechanism. Saturday's tally of UK Maritime Trade Operations reports logged 103 hulls entering the Strait of Hormuz and 89 leaving — a 27 percent weekly rise registered in the middle of a blockade war, as this paper documented. [1] The next count arrives after Treasury's sanctions rollout landed Monday, which changes what the number measures.

Sanctions of this species work through insurance certificates, charter-party clauses and protection-and-indemnity renewals — exactly the desks that produced last week's rise by deciding one risk premium beat another. [1] If the rollout names enforcement machinery rather than categories, expect underwriters to reprice and the count to sag. If it lands as announcement without mechanism, traffic resumes climbing, because the market will have confirmed that threats are a cost-free genre. Tehran, meanwhile, advanced a toll draft through a parliamentary commission that would charge ships for the passage, adding a second layer of paperwork to the same water. [2]

The caveats still apply. Lloyd's List Intelligence, counting only cargo carriers above 10,000 deadweight tons over complete weeks, logged 73 transits in the August 10-16 window, down from 91 the week before — a falling series beside the rising one. [3] Different fleets, different windows, different light. Neither number is the strait.

So the watch item is boring and decisive: this weekend's tally, read against insurance quotes rather than communiqués. The market, not either ministry, files the honest report. [1]
