Even so, US oil futures were trading at more than $61 a barrel during Asia hours — a spike of nearly 10%. Earlier, the price jumped as much as 15%. Futures of Brent crude, the global benchmark, traded at nearly $68 per barrel, an 11% increase.
Gasoline futures, meanwhile, were up about 9%.
“This is a big deal,” said Tom Kloza, chief oil analyst for the Oil Price Information Service. “It is the biggest shock to the oil markets since [Hurricane] Katrina. And like Katrina it will likely haunt us for months, at least weeks.”
Kloza said gasoline prices will likely “creep up” this fall, rather than drop steadily, as they historically have done.
Prices had been slumping
Oil prices had been in a slump. Brent closed at $60.22 per barrel on Friday, down from a high of $74.57 in April. The price closely followed in the United States, known as WTI, closed at $54.85, a 17% drop from April’s highs.
Saudi Arabia, the world’s largest oil exporter, had cut back on production of crude and other energy products as part of an OPEC effort to boost prices. The kingdom produces approximately 10% of the total global supply of 100 million barrels per day.
Saturday’s coordinated drone strikes on key Saudi Arabian oil facilities disrupted about half of the kingdom’s oil capacity, or 5% of the daily global oil supply. The location is the world’s largest oil processing plant. Saudi Energy Minister Prince Abdulaziz bin Salman said that 5.7 million barrels a day of crude oil and gas production have been affected.
Early reaction in Asia
Asian stocks also reacted to the strikes during trading hours Monday.
Airline stocks in Asia, meanwhile, tumbled. Fuel is a massive expense for airlines, so their stocks are typically hit when there is a major surge.
China’s three biggest airline operators all dropped sharply in Hong Kong. China Eastern Airlines fell more than 4%, while China Southern Airlines and Air China each fell at least 2.5%. All three trade in Shanghai, and they also fell in that market.
India is also feeling the effects. Two of the country’s state-run oil refiners were among the biggest losers on the Bombay Stock Exchange on Monday.
The shock to oil prices is already been felt, but its longterm impact has yet to be realized. Some analysts expect the rally could be relatively small in the short term if the damage to Saudi Aramco, the state-run oil company in Saudi Arabia, is minimal.
“A small $2-$3 per barrel premium would emerge if the damage appears to be an issue that can be resolved quickly, and $10 if the damage to Aramco’s facilities is significant,” Ayham Kamel of the Eurasia Group said in a research note. Others told CNN Business they believe prices could jump even higher because of the amount of saudi oil affected by the attacks.
The fallout for stocks also depends on how long it takes Saudi Arabia to resume output, said Oscar Yee, an analyst for Citi Research in Hong Kong, in a report on Monday.
Kerry Craig, global market strategist at JPMorgan Asset Management based in Australia, said the ability of oil producers to dip into stockpiles may mitigate some of the rise in prices in the near term.
But he said in a note that the “bigger issue is what premium markets will build in to reflect the risk of further attacks.”
The United States’ strategic reserve
The reserve is a complex of four sites along the Texas and Louisiana gulf coasts that have deep underground storage caverns, 2,000 to 4,000 feet below the surface. Any oil drawn from the SPR would not give an immediate boost to global supply. It has to be pulled out of storage and then sold into the marketplace of buyers and sellers, a process that could take about two weeks.
