April 21, News: On April 21, Shandong Huifeng Petrochemical Co., Ltd. announced the latest ex-factory price for propylene, which was raised by 200 yuan/ton to 9,300 yuan/ton. Chempricehub's analysis of propylene, with a long-short rating of 1.5: On the spot side, the ex-factory price of propylene increased by 200 yuan/ton to 9,300 yuan/ton, indicating that suppliers proactively raised prices due to strong demand or cost pressures, directly benefiting the spot market and suggesting tightening supply or a recovery in downstream demand. On the futures side, considering the recent downward trend in propylene contracts on the Zhengzhou Commodity Exchange (e.g., the settlement price of the 2605 contract was 8,339 yuan), the strong upward momentum in spot prices may drive improved expectations in the futures market, leading to a rebound in the main contract. The comprehensive rating of +1.5 reflects a significant positive effect, but attention should be paid to the sustainability of subsequent demand.
