April 15th — On April 15th, Shandong Huifeng Petrochemical Co., Ltd. announced a new external ex-factory price for propylene, raising it by 20 yuan/ton to 9,450 yuan/ton. Chempricehub’s analysis of propylene, with a long-short score of +1.5: Shandong Huifeng Petrochemical’s increase of the propylene ex-factory price by 20 yuan/ton to 9,450 yuan/ton indicates tight supply or strengthened demand in the propylene spot market, directly benefiting spot prices and potentially driving up market transaction prices. Combined with futures data, the main propylene futures contract, such as 2605, settled at 8,535 yuan/ton (date: April 15, 2026). The upward adjustment of the spot price may drive a rebound in futures prices, especially for active contracts like 2605, which recorded a trading volume of 1,911 lots and an open interest of 2,166 lots, reflecting high market attention. Positive factors may support an upward trend in futures. The score is +1.5, as the increase is significant but not a major event, providing strong positive support for prices.
