Iran has closed the Strait of Hormuz following attacks by the United States and Israel but continues to export large volumes of crude oil to China, according to a CNBC report published Wednesday. Satellite data from TankerTrackers shows that since the war began on February 28, Iran has shipped at least 11.7 million barrels of crude through the strait, all bound for China. Kepler, another shipping intelligence firm, estimated the figure at around 12 million barrels. The International Maritime Organization reported that at least ten vessels have been attacked in the strait since the conflict began, leaving seven sailors dead.

Despite threats to attack any vessel attempting passage, Iran has maintained exports mainly through its Kharg Island terminal, which handles 90 percent of its shipments. Tehran has also resumed loading at the Jask terminal on the Gulf of Oman, seen as a potential alternative route. Analysts noted that China remains Iran’s main crude buyer, with February exports reaching 2.16 million barrels per day, the highest since 2018. China’s crude imports rose 15.8 percent year-on-year in the first two months of the year as it built up reserves.

Global oil prices surged to record levels amid fears of supply disruption, while U.S. President Donald Trump urged ships near the strait to proceed despite Iranian threats.
