Chempricehub Analysis of Caustic Soda, Bull-Bear Score: 1.5 The price increase of Shandong Luxi Chemical's liquid caustic soda to 650 yuan/ton indicates tight supply or increased demand in the spot market, directly benefiting spot caustic soda prices. Combined with the latest futures data, the main caustic soda contract, such as the 2605 settlement price of 2,161 yuan/ton (up +11 yuan), shows that changes in open interest reflect strengthened market bullish sentiment, with futures prices expected to continue their upward trend.
