March 11th News: On March 11th, Shandong Haike Chemical Group Co., Ltd. announced the latest propylene quotation, which was lowered by 500 yuan/ton to 8,300 yuan/ton. The 60,000-ton-per-year propylene plant is operating smoothly, with normal shipments. Chempricehub analysis of propylene, long-short score: -2. Shandong Haike Chemical's reduction of the propylene quotation by 500 yuan/ton to 8,300 yuan/ton indicates ample supply in the spot market (with smooth plant operation and normal shipments) and weak demand, leading to significant downward pressure on prices, constituting a major bearish factor. Combined with the futures market, the settlement price of the propylene main contract 2605 on the Zhengzhou Commodity Exchange was 7,713 yuan/ton (2026-03-10). The sharp decline in spot prices may exacerbate the downward trend in the futures market, as the narrowing gap between spot and futures prices and the strengthening signal of oversupply are expected to put pressure on short-term futures prices.
