Oil prices surged on Monday, with Brent crude posting its biggest intra-day percentage gain since the Gulf War in 1991, after an attack on Saudi Arabian oil facilities on Saturday shut over 5 percent of global supply.
But prices came off their peaks after U.S. president Donald Trump authorized the use of the country’s emergency stockpile to ensure stable supply.
Brent crude futures, the international benchmark, rose by as much as 19.5% to $71.95 per barrel, the biggest intra-day jump since Jan. 14, 1991. By 0633 GMT, the front-month contract was at $66.31, up $6.09, or 10.1%, from its previous close.
U.S. West Texas Intermediate (WTI) futures climbed by as much as 15.5% to $63.34, the biggest intra-day percentage gain since June 22, 1998. The front-month contract was at $59.80, up $4.95, or 9%.
Saudi Arabia is the world’s biggest oil exporter and the attack on state-owned producer Saudi Aramco’s crude processing facilities at Abqaiq and Khurais has cut output by 5.7 million barrels per day. The company has not given a timeline for the resumption of full output.
A source close to the matter told Reuters the return to full oil capacity could take “weeks, not days.”
“We think the attacks would be a wake up call for investors, who have failed to price in risk within the price of crude. Although global supply will contract in the near term, the United States has the ability to supply this contraction,” said Hue Frame, managing director at Frame Funds in Sydney.
Countries which are major importers of Saudi crude, such as India, China and Indonesia, will be the most vulnerable to the oil supply disruption, Frame said.
Saudi Arabia’s oil exports will continue as normal this week as the kingdom taps into stocks from its large storage facilities, an industry source briefed on the developments told Reuters on Sunday.
“The attacks on critical Saudi oil infrastructure over the weekend are unlikely to reduce the kingdom’s oil exports dramatically and the markets will likely look beyond short-term supply-demand dislocations,” Barclays said on Monday.
“However, a re-pricing of supply-side tail risks will likely provide a more sustained boost to oil prices.”
President Trump said he approved the release of oil from the U.S. Strategic Petroleum Reserve (SPR) if needed in a quantity to be determined.
Trump also said the United States was “locked and loaded” for a potential response to the attack on Saudi Arabia’s oil facilities.
