January 16th News: On January 16th, Shandong Huifeng Petrochemical Co., Ltd. announced a new external ex-factory price for propylene, raising it by 70 yuan/ton to 6,220 yuan/ton. The downstream supporting 150,000 tons/year PP unit was shut down on March 22nd, with the restart time to be determined. Chempricehub Analysis: Propylene, Bull-Bear Score: 1 The ex-factory price of propylene has been raised by 70 yuan/ton to 6,220 yuan/ton, indicating tight spot market supply or strengthened demand support, which directly benefits spot prices. The shutdown of the downstream PP unit may reduce propylene demand, but the current price increase dominates the positive sentiment, and spot prices are expected to strengthen in the short term. Polypropylene, Bull-Bear Score: 1 The shutdown of the downstream PP unit will reduce market supply, benefiting polypropylene spot prices. At the same time, combined with the recent performance of polypropylene futures (e.g., the main 2605 contract closed at 6,592 yuan/ton, settled at 6,606 yuan/ton, up 30 yuan, with open interest increasing by 7,306 lots), the expectation of reduced supply and the upward trend in futures form a resonance, which is bullish for futures prices.
