Shipping data shows vessels clustering on both sides of the Strait of Hormuz, but only one transit

President Donald Trump on Monday said in a Truth Social post that ships are "starting to move" out of the Strait of Hormuz. 

The waterway is vital to the global petroleum trade, and it's been under blockades by both the U.S. and Iran for months. Vessel-tracking data on Monday showed no significant tanker crossings aside from a liquefied natural gas carrier, Reuters reported. 

Ships have been transporting oil along Oman's coast since the conflict began at the end of February, sailing with U.S. naval escorts and their transponders off. 

The tracking data only captures ships reporting their location, and dozens of tankers remain clustered on both sides of the strait. 

Jyske Bank, an analyst with Haider Anjum, said in a client note that ships are heading toward the strait, but companies will likely need more assurances of safety before they begin resuming regular transits. 

Trump announced that the U.S. and Iran have agreed to a peace deal, and a formal signing ceremony is planned for Friday in Geneva, Switzerland. 

"The shipping companies probably want to wait until it is clear that the agreement holds, as we have already had Hormuz 'open' for a very short time twice before," Bank said.
