As of January 8, 2026, the inventory of fixed caustic soda samples from enterprises with a capacity of 200,000 tons or more nationwide reached 495,200 metric tons (wet metric tons), marking a month-on-month increase of 1.96% and a year-on-year surge of 76.03%. Chempricehub's analysis of caustic soda indicates a bearish sentiment, with a rating of -1.5. The month-on-month rise of 1.96% in caustic soda inventory to 495,200 metric tons, coupled with a significant year-on-year increase of 76.03%, suggests oversupply and weak demand, exerting notable downward pressure on spot prices. In the futures market, considering recent contract data (e.g., the settlement price of the 2603 contract at 2,231 yuan per metric ton, up by 64 yuan), the accumulation of inventory may restrain future price increases and heighten the risk of a correction in futures prices. The overall rating of -1.5 reflects the bearish pressure stemming from high inventory levels.
