At their 4 October 2026 meeting the seven OPEC+ countries decided to maintain September 2026 required production for November 2026, so there was no cut, according to the OPEC press release and The National.
Resolves YES if the press release published on opec.org after the 4 October 2026 meeting announces a production level for November 2026 below the October 2026 required production level. Maintaining October's level or announcing an increase resolves NO. If opec.org has not published by 6 October, the decision as reported by at least two of Reuters, Al Jazeera and BBC News suffices.
We found seven attacks since May 2019 that fit. Each hit Gulf oil sites or military bases in the weeks before OPEC+ decided how much oil to pump. For each one we checked whether the group's next decision raised output, the same question the first market asks about 6 September.
