Crude oil-linked futures fell sharply on Monday, August 3, 2026, after reports emerged of renewed negotiation signals between the United States and Iran, according to 同花顺财经. The energy complex saw broad losses, with fuel oil dropping more than 4% at one point during the session, as reported by 新浪财经.
Polysilicon futures were the standout gainer, touching the 9% daily price limit, 同花顺财经 reported. The sharp divergence between energy and polysilicon markets highlighted a session driven by geopolitical headlines rather than broad macroeconomic data.
The move in oil came after earlier reports suggested the US-Iran talks had taken an unexpected turn, per 新浪财经. That followed a period in which international oil prices had already "braked sharply" and domestic chemical-energy futures had cooled significantly, according to cs.com.cn. The latest headlines appeared to accelerate that downward trend.
Elsewhere in the commodities complex, lithium carbonate futures fell more than 3% to a fresh stage low, according to 金融界. That decline continued a slide that had already pushed the contract below the 140,000 yuan per ton threshold on July 31, as reported by 东方财富. Container shipping (欧线) futures had rallied quickly in the afternoon of that same session, per the same outlet, though that strength did not carry over into the broader complex on Monday.
The session underscored how quickly sentiment can shift in commodity markets when geopolitical headlines change. With US-Iran talks still in flux, traders will likely watch for further updates on negotiations, as well as any follow-through in oil inventories or supply data, to gauge whether the energy selloff extends or stabilizes.
