On January 15, the total inventory of domestic soda ash manufacturers reached 1.575 million tons, an increase of 10,300 tons from Monday, representing a rise of 0.66%. This includes 837,000 tons of light soda ash inventory and 738,000 tons of heavy soda ash inventory. PriceSeek's analysis of soda ash indicates a long-short score of -1.5. The total inventory of soda ash manufacturers increased to 1.575 million tons on January 15, up by 10,300 tons month-on-month (a 0.66% increase), with light soda ash inventory at 837,000 tons and heavy soda ash inventory at 738,000 tons. The rise in inventory suggests increased pressure on the supply side and relatively weak demand, which may lead to downward pressure on spot prices. Combined with futures market data, the main soda ash contract, such as 2605, closed at 1,193 yuan per ton (down 17 yuan), and the 2603 contract closed at 1,160 yuan per ton (down 15 yuan), indicating a general decline in recent prices. Changes in open interest reflect strong bearish sentiment in the market. The news of increased inventory may reinforce the downward trend in futures prices, exerting a generally bearish influence on the long-short balance.
