Traffic through the strait has fallen to an average of 15 vessels a day in August from about 130 before the war, according to ship trackers, amid Iranian attacks and a U.S. blockade on Iran’s ports. Iran and the U.S. have sought to establish separate routes through the international strait, with Iran’s route near its shoreline and the U.S. channel following the Omani coast, where most attacks have occurred. Despite predictions that the closure would push oil above $150 a barrel, prices remain around $80, while gasoline has risen to about $4 a gallon from $2.98 before the war. The gap reflects alternative ways to move oil out of the Persian Gulf and the extent to which China has reduced its oil imports.
