Report Industry Investment Rating - Not provided in the content Core View of the Report - The current soda ash market lacks strong drivers. Under the pressure of high supply and expected future capacity increase, price rebound is weak. In the short term, it is expected to maintain a weak and volatile trend. Attention should be paid to the transfer of the main contract and changes in macro - sentiment. [7][37] - In terms of operation, it is recommended to treat it with a short - term oscillatory mindset. Considering shorting lightly on rebounds for single - side trading, temporarily observing for arbitrage, and buying put options to replace short positions for options trading. [38] Summary by Relevant Catalogs Soda Ash Supply and Demand Situation Production and Capacity Analysis - As of December 11, 2025, the weekly domestic soda ash production was 735,400 tons, a week - on - week increase of 31,500 tons or 4.48%.

Compared with the previous Thursday, it decreased by 44,300 tons or 2.88%. Year - on - year, it decreased by 140,200 tons or 8.58%. [14] Shipment Situation Analysis - As of December 11, the weekly shipment volume of Chinese soda ash enterprises was 779,700 tons, a week - on - week increase of 3.59%. The overall shipment rate of soda ash was 106.02%, a week - on - week decrease of 0.91 percentage points. [16] Profit Analysis - As of December 11, 2025, the theoretical profit (double - ton) of the co - production process of Chinese soda ash was - 49 yuan/ton, a week - on - week increase of 50.25%. The cost decreased due to stable raw material salt prices and falling power coal prices, while the soda ash price was stable and the by - product ammonium chloride price increased. [19] - As of December 11, 2025, the theoretical profit of the ammonia - soda process of Chinese soda ash was - 67.60 yuan/ton, a week - on - week increase of 1.31%.

[30] Comprehensive Analysis - Last week, the main contract of soda ash futures continued to decline in a volatile manner, and the overall market sentiment was weak. The fundamental situation was a multi - factor intertwined pattern of "increasing supply, stable demand, and inventory reduction". [37] - On the supply side, after the maintenance of some devices was completed, the weekly production and capacity utilization rate increased significantly, indicating that the high - supply state remained unchanged. [37] - There was still rigid demand support, and the shipment of enterprises was acceptable, driving the continuous decline of the total inventory of manufacturers for several weeks, and the year - on - year change had turned negative, which gave soda ash manufacturers a certain price - holding mentality. [37] - However, the absolute level of inventory was still high, and the expectation of new capacity in the future continued to suppress the market. The trading atmosphere in the spot market was average, and downstream procurement was mainly for low - price rigid demand, with insufficient intention for large - scale stockpiling. [37] - On the cost side, the decline in power coal prices improved the profit of the co - production process, but the industry as a whole was still in the loss range, which formed a bottom support. [37]

The inventory days were 26.8 days, a 0.7 - day decrease from the previous period [32]. 3.5 Comprehensive Analysis - **Market Situation**: This week, the price of the main soda ash futures contract declined under pressure, with a significant weekly decline, and generally maintained a narrow - range oscillating pattern at a low level. The core market contradiction lies in the game between future production increase pressure and the marginal improvement of the current fundamentals. - **Negative Factors**: The supply pressure is the main suppressing factor. The production increased slightly week - on - week, especially after some large - scale plants ended maintenance, the supply recovered. In addition, the market's expectation of the gradual release of new production capacity in Inner Mongolia is increasing, which suppresses the far - month contracts and the overall market sentiment. - **Positive Factors**: The total inventory of manufacturers continued to decline this week, and the inventory of heavy soda ash decreased significantly, alleviating the supply - demand pressure in the short term. At the same time, the industry as a whole is still in a loss state, and the profit of the ammonia - soda method has further declined, providing strong cost support for the price and limiting the downside space. 3.6 Operational Suggestions - **Single - side Trading**: Adopt a short - term oscillating mindset, and it is recommended to sell high and buy low within the oscillating range, and avoid chasing up or selling down. - **Arbitrage**: Temporarily wait and see. - **Options**: Consider selling the wide - strangle option strategy when appropriate [40].
