Core Viewpoint - The current core issue in the soda ash market has shifted from simple price fluctuations to a cost competition among different production processes [1][14]. Market Dynamics - As of December 16, 2025, the main contract for soda ash (SA401) closed at 1463 yuan/ton, down 2.66%, indicating ongoing volatility around the cost line [2]. - The price range of 1160 to 1190 yuan/ton has been observed, with total domestic soda ash inventory at 1.4943 million tons, remaining historically high despite a slight decrease in social inventory [5]. - The supply side has seen reduced operating rates due to losses and maintenance, while demand from the float glass industry has weakened due to ongoing losses [5][6]. Cost Structure - The production of soda ash is primarily divided into three processes: ammonia-soda process, soda-lime process, and natural soda process, with significant cost differences [14]. - The natural soda process can maintain costs below 1000 yuan/ton, while the soda-lime process has a cost center around 1050 to 1200 yuan/ton, and the ammonia-soda process exceeds 1300 yuan/ton [14]. - Companies using the ammonia-soda process are facing severe losses, leading to difficult decisions regarding production and maintenance [15]. Market Behavior - Low-cost producers are adopting strategies to increase market share, while high-cost producers are caught in a "prisoner's dilemma," where reducing production could lead to loss of market share [16]. - The industry consensus is forming around the need for high-cost capacity to exit the market to restore supply-demand balance [17]. Trading Strategies - The trading logic is evolving due to the lack of clear trends, with participants focusing on basis, price spreads, and process profits [19]. - Companies are shifting to dynamic and proportional hedging strategies, adjusting their positions based on price movements relative to production costs [20]. - The options market is becoming more active, providing new tools for companies and investors to manage uncertainty [21].

Report Industry Investment Rating No relevant information provided. Core Viewpoints - After the Central Economic Work Conference, the macro - positive factors faded, and pricing returned to fundamentals. Steel supply is reducing, but the recovery of steel mill profits may slow down the reduction speed. Demand is seasonally weak, and steel exports are expected to tighten. Steel inventories show different trends, with short - term prices fluctuating weakly [3]. - After macro events, trading logic returned to fundamentals. Iron ore supply from major mines is restricted, and steel mills have a need to replenish inventory. Iron ore demand is seasonally declining but is expected to rebound in January. Falling coking coal prices provide support, and the downside price space is limited [21]. - Coking coal supply has limited marginal changes, but due to pressure on steel mill profits and unexpected reduction in hot metal production, coking coal supply exceeds demand. Coke production decreased slightly last week due to environmental restrictions. With the decline in coking coal costs, coke prices are likely to continue to fall [31]. - The fundamentals of ferroalloys are weak, but news from the SASAC and the National Development and Reform Commission led to a price rebound today. However, price increases may stimulate enterprises to hedge and suppress prices [47]. - With the strengthening of new production capacity expectations, the expectation of soda ash oversupply is intensifying. The acceleration of glass cold - repair weakens the demand for soda ash. Although exports are high, high inventories restrict prices [65]. - From December to before the Spring Festival, some glass production lines are expected to undergo cold - repair, which may affect long - term pricing. Near - term contracts will follow the delivery logic, and currently, high intermediate inventories and weak end - market demand put pressure on spot prices [88].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The overall sentiment in the commodity market was weak last Friday, and the prices of finished steel products showed a weak and volatile trend. The terminal demand remains weak, and the inventory pressure of hot-rolled coils is prominent. Steel prices are expected to fluctuate in the bottom range. With the approaching of winter storage, attention should be paid to winter storage policies and price guidance [2]. - The supply of iron ore has slightly increased, while the demand has decreased, and the inventory has continued to rise. The price of iron ore is expected to fluctuate weakly, and attention should be paid to the support level of 750 yuan/ton for the weighted contract [5]. - The market is relatively optimistic about the black sector and domestic policies. It is recommended to pay attention to whether there are any unexpected situations, as well as the inflection points of sentiment and prices [9]. - The supply and demand pattern of manganese silicon is not ideal, while that of ferrosilicon remains basically balanced. The future market trends of these two products will be mainly influenced by the direction of the black sector and cost increases [10]. - The price of industrial silicon is expected to be weak in the short term, and it may rebound if the sentiment of "anti-involution" related commodities improves. Attention should be paid to new supply-side disturbances in the northwest [14]. - The price of polysilicon is expected to be affected by the "anti-involution" policy and the weak supply and demand situation. Attention should be paid to the pressure level of 60,000 yuan for the futures contract [16]. - The float glass market is in a state of weak supply-demand balance and is expected to continue to show a narrow-range fluctuation trend in the short term [19]. - The price of soda ash is expected to continue to decline under pressure in the short term.

The price is expected to be weak in the short term and may rebound if the sentiment of related commodities improves [14]. - The production of polysilicon is expected to continue to decline in December, but the decline may be limited. The downstream demand is weak, and the inventory pressure is difficult to relieve. Attention should be paid to the pressure level of 60,000 yuan for the futures contract [16]. Glass and Soda Ash Market Quotes - The glass main contract closed at 964 yuan/ton on Friday afternoon, a decrease of 2.03% (-20).
