An attack on September 14 damaged Saudi Aramco's Abqaiq processing plant and Khurais oil field, cutting Saudi output sharply. Brent and WTI posted their largest single-day gain in a decade on September 16, and Saudi Aramco said Abqaiq was back to 2 million bpd with full capacity expected by end-September.
The outage removed a large share of global supply and widened risk premiums, lifting crude and gasoline prices; the fast restoration plans then pulled prices back, so the outcome depends on how quickly output returns.
