March 30th News: Major alumina manufacturers in Shandong have raised the purchase price of 32% ion-exchange membrane caustic soda by 20 yuan/ton starting March 29th, with the ex-factory price set at 630 yuan/ton. Chempricehub's analysis of caustic soda indicates a bullish-bearish score of +1.5. The increase in the purchase price of 32% ion-exchange membrane caustic soda by major alumina manufacturers in Shandong by 20 yuan/ton to 630 yuan/ton ex-factory reflects strong downstream demand and tight supply, directly benefiting the spot price of caustic soda. In the futures market, the main caustic soda contract, such as SH2605, recently settled at 2,461 yuan/ton (data as of March 27th). However, this price adjustment event may boost market expectations and drive futures prices upward. A score of +1.5 indicates a significant positive impact, as the price adjustment is reasonable and involves a core downstream industry. However, attention should be paid to subsequent changes in supply and demand.
