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.

Deep Analysis

In plain English

Oil is bought and sold on futures exchanges, where a price moves all day and then a single closing figure, the settlement, goes in the record. On Friday 11 September news of the attack on the Saudi pipeline pushed Brent Crude, the main global benchmark, up to around $109.98 at one point. By the close it had fallen back to $104.61, which was below Thursday's closing price. The American benchmark, West Texas Intermediate, closed at $100.05. So the market got excited and then changed its mind inside a single day. Exchanges are shut at the weekend, which means anything that happened on Saturday or Sunday has to wait until Monday to show up in a price at all.

What could happen next?

    A spike that unwinds inside one session prices a disruption to a route rather than a loss of barrels.

  • Risk

    Two days of weekend news sit unpriced, and the first settlement able to carry them is Monday 14 September.

    Immediate · Assessed
  • Consequence

    A forecaster raising its shut-in estimate while the market lowers its close leaves buyers hedging against two different views of the same quarter.

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.
Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.
Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
