This followed attacks on Friday on Saudi Arabia, which Riyadh blamed on Iranian-backed fighters in Iraq, that disrupted the country's East-West pipeline, which allows oil exports to bypass the blockaded Strait of Hormuz, through which about a fifth of global oil supplies previously passed.
Saudi Arabia could exhaust crude available for export within days unless the East-West pipeline resumes operations, according to buyers and traders. The pipeline strike threatened up to 4% of global oil supply.
"The recent attack may be more severe and could threaten the remaining 2mb/d of recent Yanbu exports, with the latest repair assessments ranging from 'very soon' to eight weeks," Goldman Sachs said in a note.
The attacks on oil infrastructure marked a meaningful escalation of the conflict and increased the probability of Brent rising above $120 a barrel, Goldman Sachs said, citing a scenario in which average Gulf oil output in 2027 remains 4 million barrels per day below pre-war levels.
Commodity vessel traffic through the Strait of Hormuz dropped to four on Monday, down from 10 a day earlier, preliminary data from Kpler showed on Tuesday, raising concerns about a route that carried about a fifth of global oil supplies before the U.S.-Israeli war on Iran kicked off on February 28.
"In the absence of an adjustment in demand or greater oil flows through the Strait of Hormuz, several weeks of the East-West pipeline being closed could lift Brent crude prices towards $130 per barrel," Hussain said.
