China’s COSCO and CMES pull oil tankers out of Hormuz and Bab el-Mandeb

Two of China's biggest state shippers have pulled their oil tankers out of the two waterways that carry the world's crude. COSCO Shipping Energy Transportation and China Merchants Energy Shipping stopped sending tankers through the Strait of Hormuz and the Bab el-Mandeb in late July, according to Reuters and industry sources. The freeze was picked up by tanker trackers and confirmed on 18 August.

Between them the two firms control more than 100 VLCCs. Each holds about two million barrels. Before the Iran war they moved roughly half of China's Middle East crude imports, apart from sanctioned Iranian oil.

Reuters reported that about two dozen of their tankers are booked to load outside the Persian Gulf from August through mid-September. The loading points sit at Fujairah and Omani anchorages. Chinese-linked crews are also using STS transfers in the Gulf of Oman, and those runs ran above 600,000 barrels a day in June and July. That is a lot of oil outside the choke point.

The rerouting followed calls from Chinese central authorities. Daily earnings for a VLCC on these routes have jumped to around $110,000, from $30,000 to $40,000 before the war, so the alternative loading also pays.

The Strait of Hormuz still carries about a fifth of the world's seaborne oil in normal times. Traffic through it has thinned as the conflict has widened. Fujairah is filling in as the swap point.

The pattern is not a one-off diversion. It is a settled change of course by the largest state shipping firms in the biggest oil buyer, and it says a lot about Beijing's read of the risk.
