Chempricehub's analysis of caustic soda indicates a bearish sentiment with a score of -1. The month-on-month increase of 4.93% and year-on-year rise of 14.28% in inventory suggest oversupply and weak demand, exerting downward pressure on spot prices. The settlement price of the main futures contract 2605 stood at 2,521 yuan per ton, down by 60 yuan, while open interest decreased by 4,801 lots, reflecting a strengthening bearish sentiment in the market. Short-term prices are likely to remain under pressure.
