Commodity vessel traffic through the Strait of Hormuz slowed on Thursday as uncertainty continued to affect Middle East shipping amid stalled U.S.-Iran peace talks, according to ship-tracking data from Kpler.

Seven commodity ships were recorded sailing through the waterway, half the tally reported on the previous day. Four vessels entered the strait and three exited.

The Strait of Hormuz handled nearly one-fifth of global crude oil and liquefied natural gas shipments before the war began in February. Thursday’s movements did not include any very large crude carriers or LNG tankers.

Kpler data did, however, show that one very large gas carrier transited out of Hormuz using the Iranian route. The vessel was carrying propane and butane.

Shipping activity also eased at the Bab el-Mandeb strait on Thursday compared with the preceding two days. A total of 23 commodity vessels transited the waterway, down from 34 on each of the previous two days.

Of Thursday’s total at Bab el-Mandeb, 16 ships entered and seven exited. Two of the outbound vessels were Suezmax crude oil tankers. The Stoic Warrior was carrying crude destined for Vietnam, while the Dokos was transporting a crude cargo bound for India.

No very large crude carriers or LNG tankers were recorded passing through Bab el-Mandeb during the day.

The figures reflect vessels visible through ship-tracking systems. Ships navigating either waterway with their transponders switched off are not included in Kpler’s data, meaning the reported totals may not capture all maritime movements.
