Oil swings $30 in a single session

Brent hit $119.50 — the highest since 2012 — then crashed below $90 on a single presidential comment. The most volatile crude session in decades reveals a market trading on words, not barrels.

Brent Crude hit $119.50 per barrel on Monday morning — the highest since 2022 and a 77% rise from $67.41 on 27 February, the day the war began. WTI reached $119.48. By the US close, Brent had settled at $98.96, sinking below $90 in after-hours trading. WTI settled at $94.77. The $30 intraday reversal was driven by Trump's 'very soon' language on ending the war and profit-taking on overcrowded long positions.

The $30 swing dwarfs normal oil market volatility. Brent's average daily range through 2025 was approximately $2. Even during the 2020 pandemic price collapse, intraday moves rarely exceeded $10. Last Friday, US crude futures posted a 35.63% weekly gain — the largest since the contract began trading in 1983. Qatar's energy minister warned of $150 per barrel if Hormuz remains closed. The market touched $119 and flinched — but the flinch was triggered by a presidential remark, not by any change in the physical supply picture. Brent had been at $116.08 just three days ago, itself a 72% rise in under two weeks. The 1990 Iraqi invasion of Kuwait doubled oil prices over two months; this war achieved the same effect in ten days and then gave back a third of it in an afternoon.

The underlying supply disruption has not changed. Tanker traffic through Hormuz remains down approximately 70%. Kuwait's force majeure removed 300,000 barrels per day from export markets. Combined with Iraq's curtailments of approximately 1.5 million barrels per day, roughly 3.5 million barrels per day of Gulf production capacity is shut in or unable to reach market. No tanker insurance has been restored. No diplomatic off-ramp for Hormuz has materialised. The fundamental imbalance — supply removed, demand unchanged — is identical to what it was at $119 in the morning. What moved was sentiment, and sentiment moved on words.

The question for Tuesday's Asian open is whether $90 or $100 becomes the new floor. If $90 holds, the oil shock remains a market event — painful but absorbable for import-dependent economies, even those already strained (South Korea's KOSPI triggered two circuit breakers in four sessions). If $100 holds, it crosses into macroeconomic damage: compressed industrial margins, inflationary pressure on food and transport costs across Asia and Europe, and political pressure on governments to release strategic petroleum reserves or seek bilateral supply deals outside The Gulf. The market is not pricing oil. It is pricing the probability that one man's 'very soon' means what it says.

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 (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.
Korea Shipowners' Association

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.
