2、 Market analysis
The commodity analysis system shows that the price of caustic soda has been running steadily this week. The price of caustic soda in Shandong region is around 650-720 yuan/ton in the mainstream market of 32% ion-exchange membrane alkali. The price of caustic soda in Zhejiang region is stable, with a mainstream market price of 930-960 yuan/ton in 32% ion-exchange membrane alkali. The price of caustic soda in Inner Mongolia region is stable, with a mainstream market price of 2250-2350 yuan/ton (converted to 100%) in 32% ion-exchange membrane alkali. This week, the inventory of caustic soda enterprises has decreased, and external orders have continued, resulting in an increase in caustic soda prices. The periodic supply imbalance of downstream alumina has led to price increases, and the overall enterprise has a reluctance to sell. It is expected that the alumina market will fluctuate in the later stage.
Analysts believe that in the near future, the price of caustic soda has remained strong this week, and the recent rise in downstream alumina prices in China is favorable for caustic soda. The comprehensive supply-demand game predicts that caustic soda may continue to maintain a strong operating market in the later stage, depending on downstream market demand.
