新产能持续释放 烧碱重心将逐步下移

Core Viewpoint - The caustic soda market is expected to face a structural oversupply in 2026, with supply growth outpacing demand growth, leading to a continued downward pressure on prices [1][5][6] Supply and Demand Dynamics - In 2025, the price of caustic soda fell from a peak of 3332 CNY/ton to 2098 CNY/ton, a decrease of 1234 CNY/ton, primarily due to an imbalance between capacity expansion and demand growth [1] - Domestic caustic soda production capacity increased by 210 million tons in 2025, contributing to a long-term oversupply situation [1] - The aluminum oxide industry, which accounts for 30%-40% of caustic soda demand, is expected to add approximately 11 million tons of capacity in 2025, theoretically increasing caustic soda demand by 1.2 million tons, but actual production is limited by bauxite supply constraints [1][2] - In 2026, the planned new capacity for caustic soda is about 2.19 million tons, with total domestic production expected to reach 43.86 million tons [2] - The overall demand growth for caustic soda in 2026 is projected to slow down compared to 2025 [3] Inventory and Market Pressure - By the end of 2025, caustic soda inventories exceeded 3 million tons, indicating a persistent oversupply [1] - In 2026, inventory pressure is expected to increase significantly, with most companies maintaining inventories above 450,000 tons [2] Cost Factors - The cost support for caustic soda prices is weak, with electricity and raw salt being the main cost components, accounting for 50%-60% and 25% respectively [4] - The price of liquid chlorine, which is produced alongside caustic soda, fluctuated between -650 to 275 CNY/ton in 2025, affecting the pricing dynamics of caustic soda [4] Policy Implications - The "anti-involution" policy proposed by the Ministry of Industry and Information Technology aims to eliminate outdated capacity, potentially impacting caustic soda supply if effectively implemented [5][6] - The actual execution and impact of this policy remain uncertain, and its development will be crucial for the market in 2026 [5][6]
