What are the key drivers behind the sharp intraday plunge and subsequent rapid recovery in the crude oil futures market, and how will the trend unfold going forward?
On Wednesday, the crude oil front-month contract fell first and then rebounded, with trading volume expanding notably. As of the close on October 21, 2026, the crude oil 2612 contract settled at 716.5 yuan per barrel, down 10.8 yuan per barrel, or 1.48%, from the previous trading day's settlement price. What were the core drivers behind the dramatic intraday selloff followed by a swift rebound, and how will the market evolve from here?
Drivers: Pulse Pricing of Geopolitical Rumors and Structural Support from Supply Gaps
The sharp intraday drop and rapid recovery stemmed from the quick release and subsequent debunking of rumors regarding US-Iran mediation progress. According to reports, the market briefly circulated news that the US and Iran had preliminarily accepted a Pakistan-brokered proposal, causing Brent crude to plunge from intraday highs, but diplomats later clarified that "a deal is imminent" was untrue, and oil prices recovered their losses. News of a compromise plan between Qatar and Pakistan initially fueled expectations of eased shipping restrictions through the Strait of Hormuz. Still, Iran denied approaching a deal, and Iran's Revolutionary Guard claimed a tanker struck a mine and caught fire in the Strait of Hormuz, rapidly dismantling the bearish narrative. The intraday decline was essentially a pullback of rumor-driven premium, while the rebound reflected a repricing of the reality of supply disruptions.
The rebound's staying power came from the hard gap in strait transit rather than mere sentiment recovery. Kpler data indicated that transport volumes through the strait had fallen significantly from pre-war benchmarks, with increased vessel attack incidents and strait traffic below normal navigation levels. The collapse in logistics efficiency pushed up shipping costs, making the contraction in delivered availability an independent bullish variable. EIA and API inventory data simultaneously showed drawdowns in US commercial crude and refined product stockpiles, providing empirical evidence for supply anxiety.
Upside constraints came from a directional easing of US sanctions on Russia. Trump's executive order exempted most provisions of the Graham Act, Novak stated that Russian diesel could return to traditional export destinations, and the IEA accelerated diesel reserve releases. However, while Russian oil clearance capped the upper price limit, the supply loss from the strait was not reduced as a result, and oil prices thus exhibited a pattern of initial decline followed by recovery amid high volatility.
Outlook
Looking ahead, short-term crude oil pricing power remains anchored to Strait of Hormuz transit volumes and the official stance on US-Iran mediation. Unconfirmed "deal near completion" type news will continue to create pulse-style selloffs, but before verifiable substantive recovery in strait transit emerges, the hard supply gap will constrain the depth and sustainability of declines. Intense news-driven maneuvering means oil prices will oscillate repeatedly. Should diplomatic mediation achieve substantive progress, geopolitical premium could dissipate rapidly, so chasing highs should be done cautiously with vigilance against high-level pullbacks.
Within the range, the frequency of long-short transitions remains elevated, and the odds of unilateral chasing of either rallies or declines are unfavorable. The relatively certain opportunity lies in elevated volatility itself, with repeated tests of range boundaries providing structural windows for swing trading with strict stop-loss discipline. Follow-up monitoring should focus on whether Strait of Hormuz transit volumes show a trend of recovery, whether the US and Iran release officially confirmed negotiation progress, and the actual pace of US strategic reserve lending. These factors together determine whether the current high-level oscillation tilts toward "premium giveback" or breaks through in the direction of "gap repricing."
