Vessel transits through the Strait of Hormuz totaled 53 in the week through July 20, according to Lloyd's List Intelligence data, down from 157 the previous week, with tanker and gas carrier movements falling to 30 from 90. Kpler tracking showed daily crossings declining from averages above 20 vessels before July 15 to single digits by July 16 and remaining low thereafter.
These figures followed the reported start of a U.S. blockade and related maritime restrictions announced by Iranian authorities.
