The Persian Gulf exports approximately 18.2 million barrels of oil per day; approximately 17 million barrels per day transit through the Strait of Hormuz in tankers. Additionally, over 3.5 billion cubic feet of natural gas, approximately 18 percent of world shipments, travel through the Strait via LNG tankers.[ii] There are few alternate routes for exporting Persian Gulf oil and gas, making the Strait of Hormuz an important chokepoint.
Persian Gulf oil is shipped east to Asia, primarily to Japan, China, and India, and west to Western Europe and the United States.
