DUBAI, United Arab Emirates (AP) — Global energy prices spiked Monday by a percentage unseen since the 1991 Gulf War after a weekend attack on key oil facilities in Saudi Arabia caused the worst disruption to world supplies on record, further fueling heightened tensions between Iran and the U.S.
American officials released satellite images of the damage at the heart of the kingdom’s crucial Abqaiq oil processing plant and a key oil field, alleging the pattern of destruction suggested Saturday’s attack came from either Iraq or Iran — rather than Yemen, as claimed by Iranian-backed Houthi rebels there. A Saudi military spokesman later made the same accusation, alleging “Iranian weapons” had been used in the assault.
Iran rejected the allegations, with a government spokesman saying now there was “absolutely no chance” of a hoped-for meeting between Iranian President Hassan Rouhani and President Donald Trump at the U.N. General Assembly next week.
For his part, Trump sent mixed signals, saying his “locked and loaded” government waited for Saudi confirmation of Iran being behind the attack while later tweeting that the U.S. didn’t need Mideast oil, “but will help our Allies!”
The tensions have led to fears that action on any side could rapidly escalate a confrontation that’s been raging just below the surface in the wider Persian Gulf in recent months. There already have been mysterious attacks on oil tankers that Washington blames on Tehran, at least one suspected Israeli strike on Shiite forces in Iraq, and the downing of a U.S. military surveillance drone by Iran.
Those tensions have increased ever since Trump pulled the U.S. out of Iran’s 2015 agreement with world powers that curtailed its nuclear activities and the U.S. re-imposed sanctions on the country that sent its economy into freefall.
Benchmark Brent crude gained nearly 20% in the first moments of trading Monday before settling down to over 10% higher as trading continued. A barrel of Brent traded up $6.45 to $66.67.
That spike represented the biggest percentage value jump in Brent crude since the run-up to the 1991 Gulf War that saw a U.S.-led coalition expel Iraqi dictator Saddam Hussein’s forces from Kuwait.
U.S. benchmark West Texas crude was up around 10%. U.S. gasoline and heating oil similarly were up.
The attack halted production of 5.7 million barrels of crude a day, more than half of Saudi Arabia’s global daily exports and more than 5% of the world’s daily crude oil production. Most of that output goes to Asia.
At 5.7 million barrels of crude oil a day, the Saudi disruption would be the greatest on record for world markets, according to figures from the Paris-based International Energy Agency. It just edges out the 5.6 million-barrels-a-day disruption around the time of Iran’s 1979 Islamic Revolution, according to the IEA.
Though the world’s overall energy demands in the past were smaller, the Saudi outage has sparked concern among analysts of prices pushing to $80 a barrel and beyond. Publicly traded airlines, whose major costs include jet fuel, suffered globally. That could in turn push up prices on everything from travel to a gallon of gas at the pump.
Saudi Arabia has pledged that its stockpiles would keep global markets supplied as it rushes to repair damage at the Abqaiq facility and its Khurais oil field. However, Saudi Aramco has not responded publicly to questions about its facilities.
Yemen’s Houthi rebels, who have been targeted by a Saudi-led coalition since March 2015 in a vicious war in the Arab world’s poorest country, maintain they launched 10 drones that caused the extensive damage. They reiterated that Saudi oil sites remained in their crosshairs, warning foreign workers to stay away.
U.S. officials say that the damage done to the north-facing parts of the facilities suggest the attack instead came across the Persian Gulf from Iraq or Iran. American officials have yet to offer substantial evidence to support their claims, though Iran in the past has relied on hard-to-attribute attacks or proxy forces to launch assaults against its enemies.
At a news conference Monday night, Saudi military spokesman Col. Turki al-Maliki said the kingdom’s initial investigations showed “the terrorist attack did not come from Yemen as claimed by the Houthi militia.”
“This terrorist attack is a large-scale cowardly act, and as I said, targets the global economy and not just the kingdom,” al-Malki said. “All the indications and operational evidence, and the weapons that were used in the terrorist attack, whether in Buqayq or Khurais, indicate with initial evidence that these weapons are Iranian weapons.”
Al-Maliki offered no immediate evidence to support his allegations, which came after Trump said the U.S. awaited word from Saudi Arabia about who it suspected launched the attacks.
Iraqi Premier Adel Abdel-Mahdi said he received a call Monday from U.S. Secretary of State Mike Pompeo, who confirmed that the attack didn’t come from Iraq. The State Department did not immediately acknowledge what was discussed. Iraq is home to Iranian-backed Shiite militias who aided it in its fight against the Islamic State group.
Iranian Foreign Ministry spokesman Abbas Mousavi again denied the U.S. claims Monday, telling journalists the accusation was “condemned, unacceptable and categorically baseless.” Government spokesman Ali Rabiei meanwhile said a Trump-Rouhani meeting in New York as of now wouldn’t happen.
“Currently we don’t see any sign from the Americans which has honesty in it, and if the current state continues there will be absolutely no chance of a meeting between the two presidents,” Rabiei said.
Russia’s Foreign Ministry, while expressing “grave concern” about the attack, warned against putting the blame on Iran, saying that plans of military retaliation against Iran are unacceptable.
U.S. satellite photos released overnight Monday appeared to show the attack on Abqaiq, the world’s largest oil processing facility, may have struck the most sensitive part of the facility, its stabilization area. The Washington-based Center for Strategic and International Studies has said the area includes “storage tanks and processing and compressor trains — which greatly increases the likelihood of a strike successfully disrupting or destroying its operations.”
Stabilization means processing so-called sour crude oil into sweet crude. That allows it to be transported onto transshipment points on the Persian Gulf and the Red Sea, or to refineries for local production.
Fernando Ferreira, the director of geopolitical risk at the Washington-based Rapidan Energy Group, said rebuilding that infrastructure “will take many months.”
Saudi Aramco did not respond to questions from The Associated Press regarding damage at Abqaiq and the satellite images.
