At least five supertankers carrying a total 10 million barrels of Saudi oil loaded from Ras Tanura have exited the Strait of Hormuz, with Saudi Aramco switching to spot pricing to speed sales in Asia, according to trade sources and shipping data, Reuters reports.

Saudi Aramco resumed loadings from Ras Tanura, the world’s largest oil port, on Friday after a halt of nearly four months.

The Saudi national oil company is ramping up loadings and shipments to Asia, adding to a prompt glut that has depressed Brent crude to about $70 a barrel from close to $120 in March following the interim US-Iran peace deal.

In addition to using its Bahri tanker fleet to deliver the cargoes, the world’s top oil exporter has offered the crude to its Asian customers on a spot pricing basis to attract demand as competition among suppliers heats up, say several trade sources who have declined to be named due to the sensitivity of the matter.
