Brent fell below $100 on 22 September 2026, to a low of $97.43 according to The Guardian, and the next day's Guardian report puts Brent up $2.3 at $101.61, which places the 22 September settlement at about $99.3. The ICE Futures Europe page and the Reuters settlement report could not be read by script, so this rests on The Guardian.
The Brent market resolves on the settlement price for front-month Brent crude reported by ICE Futures Europe on any trading day up to and including 9 October 2026; a single settlement below $100.00 resolves YES, and an intraday dip that does not carry into the settlement does not count. Where the exchange figure is not to hand, the price reports in the Guardian, Reuters or the BBC are the backup, and two of them must agree.
Brent has risen back above $100 a barrel eight times since 2011, counting only rises reported by the publications we use. Five of them came this year, during the war with Iran. For each one we checked whether the price fell below $100 again within 30 days.
