Oil prices surge 15pc after attack on Saudi facilities hits global supply

• US gasoline futures jumped 11pc.
• Brent crude futures jumped more than 19pc to a session high of $71.95 a barrel.
• State oil giant Saudi Aramco said the attack cut output by 5.7 million barrels per day.

NEW YORK: Oil prices surged more than 15pc to their highest level in nearly four months at the open on Sunday after an attack on Saudi Arabia's oil facilities on Saturday that knocked out more than 5pc of global oil supply.

Brent crude futures jumped more than 19pc to a session high of $71.95 a barrel at the opening, while US crude futures surged more than 15pc to a session high of $63.34 a barrel. Both benchmarks rose to the highest since May.

Prices were up about 12pc by 6:29 p.m. (2229 GMT), giving up some gains after US President Donald Trump said he authorized the release of oil from the US Strategic Petroleum Reserve (SPR) if needed in a quantity to be determined because of the attack on Saudi's facilities.

State oil giant Saudi Aramco said the attack cut output by 5.7 million barrels per day, at a time when Aramco is trying to ready itself for what is expected to be the world's largest share sale.

Aramco gave no timeline for output resumption. A source close to the matter told Reuters the return to full oil capacity could take "weeks, not days."

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 surge in prices is the natural knee jerk reaction but the path ahead and ability to sustain at elevated levels remains dependent on the duration of the outage, the ability to meet export commitments through domestic drawdowns, demand elasticity at higher prices as well as government and agency policy," said Michael Tran, managing director of energy strategy at RBC Capital Markets in New York.

"Even if the outage normalizes quickly, the threat of sidelining nearly 6pc of global oil production is no longer a hypothetical, a black swan or a fat tail. Welcome back, risk premium."

The attack on plants in the heartland of Saudi Arabia's oil industry, including the world's biggest petroleum-processing facility, came from the direction of Iran, and cruise missiles may have been used, according to a senior US official.

Saudi Arabia is set to become a significant buyer of refined products after attacks on Saturday, consultancy Energy Aspects said in a note.

State oil firm Saudi Aramco will likely buy significant quantities of gasoline, diesel and possibly fuel oil while cutting liquefied petroleum gas exports.

US gasoline futures jumped 11pc, while US heating oil futures rose about 6.5pc at the open.
