Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core View of the Report Last week, the soda ash market showed a pattern of weak supply and demand but with marginal improvement. The supply - side pressure reappeared as weekly production and capacity utilization increased. The demand was dull, with downstream industries purchasing on a just - in - time basis. Although the enterprise inventory decreased, the absolute level was still high, and the profit situation worsened. The core market contradiction lies in the game between high supply, high inventory, and weak demand. In the short term, the market lacks a clear directional driver and is expected to continue the oscillatory pattern. Key factors to watch include the sustainability of inventory reduction, the strength of downstream demand recovery, and whether industry losses will lead to more production cuts. [40] 3.
