After the US-Iran agreement, dozens of ships will go through the Strait of Hormuz

Most of the tankers that crossed the coast a few days ago were linked to Iran as part of the deal following the lifting of the US naval embargo.

At least 30 tankers have left the Gulf loaded with Iranian oil and petrochemicals since the deal was reached, said Jemima Shelley, senior research analyst at the Joint Nuclear Iran Campaign and Monitoring Group.

The US Treasury has eased decades of sanctions by allowing Iran to sell crude oil, petrochemicals and other oil products until August 21.

On Monday, at least five tankers under U.S. sanctions for ties to Iran moved off the coast, carrying up to four million barrels of oil, according to ship tracking data.

“That said, ‘normal’ trading has also increased,” said Martin Kelly of crisis management firm EOS Risk Group.

Four liquefied natural gas tankers were spotted on ship tracking platforms en route to Qatar’s Ras Laffan port on Monday, and at least three tankers and three cargo ships left the Gulf on Tuesday.

All of these shipments were made through Iran’s authorized northern route through Iranian waters, rather than the southern route near the coast of Oman, through Iranian waters.

And, ship tracking data shows, more than 250 tankers and 440 cargo ships are still in the Gulf, based on their last reported locations. More than 80% of tankers are stationary or at anchor and one in six appears to be carrying cargo.
