On January 12, Shandong Huifeng Petrochemical Co., Ltd. announced a new external ex-factory price for propylene, raising it by 50 yuan/ton to 6,000 yuan/ton. The downstream 150,000-ton/year PP unit was shut down on March 22, with the restart time yet to be determined. PriceSeek Analysis: Propylene, Bull-Bear Score: 1 The ex-factory price of propylene was raised by 50 yuan/ton to 6,000 yuan/ton, directly reflecting tight supply in the spot market or rising costs, which is favorable for propylene spot prices. The increase of approximately 0.83%, though not substantial, is significant, indicating strong price support from the company, likely driven by raw material costs or short-term demand. Polypropylene, Bull-Bear Score: 1 The shutdown of the downstream 150,000-ton/year PP unit, with an undetermined restart time, will reduce polypropylene supply, benefiting spot prices. Additionally, combined with polypropylene futures data (e.g., the closing price of the main contract 2605 at 6,514 yuan/ton), the supply disruption may drive up futures prices, as the shutdown intensifies market expectations of tightening supply-demand balance.
