Brent Crude spiked intraday to roughly $109.98 on Friday 11 September 2026, around 6 per cent higher overnight on news of the attack on the Saudi east-west crude line and its highest since early May, then settled the same session at $104.61, down 2.81 per cent1. West Texas Intermediate, the US benchmark, settled at $100.05, down 2.37 per cent2.
Both numbers are Friday's, and both close a session that began with the pipeline news. Brent settled at $71.99 on 26 June, and Friday's close sits far above that on the same benchmark. The US Energy Information Administration had raised its forecast for Middle East production shut in during the fourth quarter and pushed its recovery date into 2027 two days earlier, on 9 September.
A spike that unwinds inside a session says traders priced a disruption to a route rather than a loss of barrels. Saudi crude still reaches the water, and the Ministry of Energy has named neither a damaged segment nor a restart date, so the quantity actually removed from the market is unknown to the people pricing it. Futures markets do not trade on Saturday or Sunday. Monday 14 September is the first settlement that can price anything that happened over the weekend.
