2、 Market analysis
According to the commodity analysis system, the price of caustic soda has been relatively stable this week. The price of caustic soda in Shandong region has risen, with the mainstream market price of 32% ion-exchange membrane alkali being around 610-690 yuan/ton. The price of caustic soda in Zhejiang region remains stable, with the mainstream market price of 32% ion-exchange membrane alkali being around 760-820 yuan/ton when delivered to Xiaoshan. The price of caustic soda in Inner Mongolia region has stabilized, with the mainstream market price of 32% ion-exchange membrane alkali being around 1900-1950 yuan/ton (converted to 100%). This week, the price of caustic soda is mixed with long and short positions. On the positive side: In the later stage, there will still be chlor alkali enterprises undergoing maintenance, resulting in a decrease in production and a positive performance in enterprise inventory. Downstream alumina manufacturers are actively stocking up, providing favorable support for caustic soda prices. On the negative side: caustic soda companies have accumulated inventory, and downstream demand for non aluminum continues to be sluggish. They tend to purchase on demand, but there is no positive improvement, putting pressure on the market.
Analysts believe that in the near future, caustic soda prices have been weak this week. Downstream alumina shipments in China have been good recently, and the current alumina procurement prices are good. The inventory of caustic soda enterprises has decreased, supporting the price of caustic soda. However, due to the general acceptance of non aluminum enterprises, the comprehensive supply-demand game predicts that caustic soda may tend to consolidate, depending on downstream market demand.
