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.

Different Perspectives
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
