Chempricehub's analysis of caustic soda indicates a bearish score of -1.5. The report highlights that the spot price of 32% ion-exchange membrane caustic soda in the Shandong region has declined by 10–30 yuan/ton, reflecting ample market supply or weak demand, which constitutes a significant bearish factor for spot prices. Combined with recent trends in caustic soda futures (e.g., the closing price of the main contract 2607 on the Zhengzhou Commodity Exchange was 2,075 yuan/ton, down 16 yuan from the previous day), this event is expected to reinforce bearish expectations in the futures market, potentially leading to further downward pressure on futures prices. The score of -1.5 reflects a moderate bearish signal, as the price decline is significant but not extreme.
