ChemPriceHub Key Alert: Surge in Caustic Soda Inventory Puts Downward Pressure on Prices

As of January 15, 2026, the inventory of fixed liquid caustic soda samples from enterprises with a capacity of 200,000 tons and above nationwide reached 512,100 tons (wet tons), representing a month-on-month increase of 3.41% and a year-on-year surge of 99.64%. PriceSeek's analysis of caustic soda indicates a bearish sentiment with a score of -2. As of January 15, 2026, the inventory of caustic soda sample enterprises nationwide reached 512,100 tons (wet tons), marking a month-on-month increase of 3.41% and a year-on-year surge of 99.64%. The significant rise in inventory pressure suggests oversupply or weak demand, posing a major bearish factor for spot prices and potentially leading to price declines. The settlement prices of the main caustic soda futures contracts (such as 2603 and 2605) have continued to fall recently (e.g., the settlement price of the 2603 contract dropped by 41 yuan per ton to 2,102 yuan per ton). The news of the sharp inventory increase is expected to reinforce market bearish expectations and exacerbate the downside risks for futures prices.
