US officials say Hormuz oil flows reaching half of pre-war levels The  US  Navy is escorting dozens of vessels through the Strait of Hormuz each night, carrying millions of barrels of oil, senior US officials said on Friday. US Energy Secretary Chris Wright said vessels under US protection were carrying about seven million barrels of oil per day through the Strait of Hormuz - a substantial amount, roughly half of what was transiting the waterway before the  US-Israeli war on Iran  began on 28 February. “Flows today are approaching half of the gap, and they’re rising,” Wright told the Bloomberg Energy Security Executive Briefing in Houston, Texas.
