An intensifying Middle East conflict is threatening to throw the world’s energy market into disarray after weekend drone attacks destroyed parts of Saudi Aramco’s Abqaiq plant — one of the world’s largest processors of oil — and a separate nearby oil field.

On Saturday, the drone attacks, directed at Saudi Arabian oil facilities that account for nearly 10 million barrels of crude-oil production, resulted in massive plumes of black smoke emanating from the oil field, and a shutdown that could lead to about 50% of its production being at least temporarily thrown offline.

Prominent crude-oil strategist Phil Flynn at Price Futures Group told MarketWatch on Sunday that the drone strike was a “big deal” that could result in a major spike in crude-oil prices, because of the potential disruption to global supplies.

This isn’t the first such strike in the region, but this most recent attack highlights the vulnerability of Arabian Peninsula’s oil production and the far-reaching implications of political clashes in the Middle East on the rest of the world.

Here’s what investors need to know about the weekend drone strikes and the implications for global markets:

What happened?

Ten automated, aerial, combat drones launched an attack on Saudi Aramco’s Abqaiq plant in Buqyaq and the Khurais oil field on Saturday at 3:31 a.m. and 3:42 a.m. local time, according to Gulf News[2].

Saudi-led coalitions have launched military campaigns to stem the Houthis’ expansion. Over the years, Saudi-led airstrikes have killed Yemeni civilians, while the Houthis have used drones and missiles to attack Saudi Arabia and have also targeted vessels in the Red Sea. Saturday’s drone attack is being described as the biggest on Saudi Arabia’s oil infrastructure since Iraq’s Saddam Hussein in 1990s[3] fired missiles into the kingdom during the first Gulf War. On Saturday, Secretary of State Mike Pompeo blamed Iran for the Saudi attacks. However, he also said there was no evidence that the weekend’s drone strike came from Yemen. “We call on all nations to publicly and unequivocally condemn Iran’s attacks. The United States will work with our partners and allies to ensure that energy markets remain well supplied and Iran is held accountable for its aggression,” Pompeo said on Twitter[4].
