March 18th News: On March 18th, the caustic soda market remained generally stable, with low inventories of 32% alkali in the Zibo market, leading to a slight increase in prices. In southwestern Shandong, the mainstream transaction price for 32% ion-exchange membrane alkali was 660-710 yuan/ton; in central-eastern Shandong, the mainstream transaction price for 32% ion-exchange membrane alkali was 650-720 yuan/ton, while 50% ion-exchange membrane alkali rose to 1220-1320 yuan/ton; in northern Shandong, the mainstream transaction price for 32% ion-exchange membrane alkali was 680-720 yuan/ton. Chempricehub's analysis of caustic soda gave a bullish-bearish score of 1.5. The low inventory of 32% alkali in the Zibo market and the slight price increase, along with the rise of 50% ion-exchange membrane alkali in central-eastern Shandong to 1220-1320 yuan/ton, indicate tight spot supply and stronger demand support, which is favorable for spot prices. Combined with futures data (such as the previous day's closing price of the 2701 contract at 2526 yuan/ton), the new information may boost market expectations, drive a rebound in futures prices, and overall benefit the market.
