Saudi Arabia is offering to sell oil from off the coast of Oman, a sign that the kingdom may be following the United Arab Emirates in shuttling more barrels through the Strait of Hormuz.

State oil company Saudi Aramco is offering cargoes on a so-called ship-to-ship basis from locations including Sohar in the Gulf of Oman, people familiar with the matter said, asking not to be identified because the information isn’t public. The grades being marketed are Arab Medium and Arab Heavy, something that means it’s highly likely the barrels came from inside the Persian Gulf.
