需求稳中偏弱，供给弹性增强

1. Report Industry Investment Rating - The investment view is bearish on glass (FG) and soda ash (SA) [1] 2. Core View of the Report - In 2025, the demand for glass and soda ash was weak, and the supply was high, leading to a continuous decline in prices and a compression of industrial profits. In 2026, the weak demand will continue to suppress the upward drive of prices, but the supply elasticity will increase significantly under the influence of profit compression and policies. The fundamentals of glass and soda ash will remain loose, and prices may be more affected by supply changes [3][85][86] 3. Summary by Relevant Catalogs 3.1 Market Review 3.1.1 Glass - In 2025, glass prices were under pressure and continued to decline. The annual average price of 5mm glass in the Shahe area was about 1,100 yuan, a year - on - year decrease of 21.4%. The price fluctuations were mainly divided into three stages: continuous decline from the beginning of the year to the end of June, a rise and then a fall in the third quarter, and a continued decline under pressure in the fourth quarter. The futures price showed a contango structure, and the basis and inter - month spreads had obvious characteristics. The glass factory's profit was under pressure and fluctuated at a low level [4][7][14] 3.1.2 Soda Ash - In 2025, the supply of soda ash was strong and the demand was weak, and the price center of gravity continued to move down. The annual average price of heavy soda ash in the Shahe area was about 1,286 yuan, a decrease of 32.2% compared with 2024. The price fluctuations mainly went through four stages: a slight rise before and after the Spring Festival, a sharp decline in the second quarter, a rise and then a fall in the third quarter, and a continued decline and a new low in the fourth quarter. The basis and spreads fluctuated slightly, and the annual structure was in backwardation. The alkali factory's profit was under pressure and decreased [24][28][32] 3.2 Glass Fundamental Analysis 3.2.1 Supply Analysis - In 2025, the glass supply was mainly stable, with a slight increase followed by a decline. The production profit was under pressure, and the industry clearing was slow. In 2026, the glass factory's production profit will continue to be under pressure, and the industry may accelerate the clearing. The daily melting volume and start - up rate are expected to decline, but the reduction may still be insufficient [42][43] 3.2.2 Demand Analysis - In 2025, the glass demand was weak, with a slight improvement in stages. Real estate demand continued to decline, while manufacturing demand was resilient. In 2026, the overall demand will remain weakly stable, with real estate demand still under pressure and manufacturing demand maintaining a certain degree of support. The inventory is expected to remain at a high level and fluctuate [53][54][62] 3.3 Soda Ash Fundamental Analysis 3.3.1 Supply Analysis - In 2025, the soda ash supply was at a high level, and the new production capacity was put into operation. In 2026, the production capacity expansion will slow down, and the production capacity will start to clear in the medium and long term. The supply elasticity of alkali factories is relatively strong, and the price will continue to fluctuate greatly due to supply disturbances [64] 3.3.2 Demand Analysis - In 2025, the demand for soda ash was weakly stable, with a downward trend. The demand from float glass and photovoltaic glass was weak, while the demand for light soda ash was relatively good. In 2026, the demand for soda ash will still be an important driving factor. The demand from float glass and photovoltaic glass is expected to weaken, but the overall demand still has strong resilience [74][75][84] 3.4 Summary and Outlook - In 2025, the downstream demand for glass and soda ash was weak, and the supply was high, resulting in an imbalance in fundamentals and a continuous decline in prices. In 2026, the weak demand will continue to suppress the upward space of glass and soda ash prices, and the industrial profits will continue to be under pressure. The prices may be more affected by supply changes, and the overall fluctuation range is limited [85][86]
