SINGAPORE (Reuters) - Four liquefied natural gas tankers controlled by Qatar were heading into the Strait of Hormuz on Monday 22 June 2026, despite a fall in ship traffic after Iran announced that it had again closed the waterway over the weekend, shipping data showed.

The tankers, Wadi Al Sail, Mekaines, Al Sadd and Mesaimeer, were entering the strait via the Iranian route for the first time since the (United States) US-Israeli war with Iran started, ship-tracking data from analytics firm Kpler showed.

QatarEnergy, whose LNG exports have been heavily curbed since the war began on 28 February 2025, did not immediately respond to a request for comment.

The Marshall Islands flagged dry bulk vessel Summit Success also entered the Gulf on Monday, LSEG data showed.

Five vessels passed through the strait on Sunday 21 June 2026, down from 26 ships spotted a day earlier, Kpler data showed. These included three Very Large Crude Carriers carrying 2 million barrels (about 318 million litres) of Saudi crude and fuel oil each, one of which was heading to Japan.

There could be more ships plying the strait with their transponders switched off.

Iran lifted its effective blockade of Hormuz last week after agreeing with the US to extend an April ceasefire for 60 days to allow for peace negotiations, but Tehran's Islamic Revolutionary Guard Corps on Saturday declared the waterway shut once again, in response to Israeli strikes in Lebanon.

Oil exports moving

The US Central Command said 55 merchant ships transited the strait on Saturday 20 June 2026 with more than 17 million barrels of oil for global markets.

Among the ships that exited the strait on Saturday, there were three VLCCs carrying crude from the United Arab Emirates, Kuwait and Iraq, and there were three tankers carrying various oil products, the data showed.

There were 13 ships that entered the strait on Saturday, including two VLCCs, the data showed.

Over 25 million barrels of Iranian oil have passed through the virtual blockade line since Monday, the head of the National Iranian Oil Company, Hamid Bovard, told state TV on Sunday.

Gulf producers Abu Dhabi National Oil Co and Kuwait Petroleum Corp have issued tenders selling crude with the option of loading from inside and outside the Strait of Hormuz.

Two vessels operated by South Korea also passed through the strait after the US and Iran signed their interim peace deal last week, Seoul's Ministry of Oceans and Fisheries said on Monday, without naming them.

Meanwhile, two ADNOC controlled LNG tankers were delivering cargoes to India on Monday, having exited the strait recently, Kpler and LSEG data showed.

The Al Hamra tanker was discharging at the Ennore LNG terminal, while the tanker Mubaraz was set to offload its cargo at the Kochi terminal on June 23, the data showed. Both tankers were last seen in ballast and east of the strait in late May to early June 2026, before reappearing on ship-tracking data over the weekend, located off the coast of India loaded with cargoes.

ADNOC did not immediately respond to a request for comment.

Al Hamra and Mubaraz have each now completed two "dark" voyages out of Hormuz since the war started.
