Ship-tracking firm Windward said just six vessels crossed the Strait of Hormuz on the night of 9-10 July, compared with 18 to 22 a few days ago.
This was the third night of reduced traffic in the critical waterway, where Iranian attacks on ships led to a renewed wave of US strikes and Iranian counterattacks on the neighbouring Gulf nations.
Outbound sailings have nearly stopped, just one vessel last night, against 15-21 on 5-7 July, Windward said in a post on X.
Windward said “dark transits”, where vessels turn their transponders off to hide their locations, are climbing and now account for nearly 40 percent of all traffic, the highest in six days.
Strait of Hormuz traffic dropped sharply overnight. Just 6 vessels crossed between 18:00 UTC July 9 and 06:00 UTC July 10, down from a normalized 18-22 earlier this month. That’s the third straight overnight drop, now near a quarter of early July levels.
