The U.S. military has helped more than 660 million barrels of crude oil pass through the Strait of Hormuz since early May, assisting about 1,300 commercial vessels, U.S. Central Command said. The operation has restored limited traffic through a southern channel along Oman after the passage was largely closed since late February, but estimates of current flows vary widely. U.S. officials said 40 tankers crossed Friday night and that about 16 million barrels had reached global markets, while other estimates put daily traffic at only three or four vessels in August or suggest flows of roughly 3 million to 5 million barrels per day. Those levels remain below the roughly 20 million barrels per day of crude and petroleum products that moved through the strait before the war. Brent crude stood at $94.39 a barrel going into the week, up from the prior week, as President Trump warned of an "economic D-Day" and a "crushing" operation against Iran. The U.S.-led effort relies on about 20 Navy warships in the Gulf of Oman, including two aircraft carrier strike groups, along with air defenses and scheduled convoys. Analysts say the mission may prevent an even sharper oil-price surge, but its limited throughput, substantial resource demands and potential to provoke Iranian attacks could undermine its strategic value.
