1. Report Industry Investment Ratings - No industry investment ratings are provided in the report. 2. Core Views - The fundamentals of the glass industry are currently weak in the short - term, and attention should be paid to the demand during the peak season. For the soda ash industry, the fundamentals have not improved, and it will experience short - term fluctuations [1]. - For soda ash, the industry pattern has not significantly improved. Supply - side production has rebounded and remained at a high level, while demand is mostly for rigid needs. Short - term upstream inventory has increased again, and the absolute inventory level is high, which is difficult to provide sufficient support based on fundamentals. Attention should be paid to market sentiment changes and coal price fluctuations. For glass, the fundamentals have deteriorated in the short - term, and there have been frequent regulatory actions by the exchange recently. Short - term risks should be vigilant, and attention should be paid to the replenishment intensity in late August [4][36]. 3.

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core View of the Report The current soda ash market has sufficient supply and weak demand. The two major downstream industries, float glass and photovoltaic glass, are in a difficult situation, with inventory on the rise. The overall market sentiment is pessimistic, and soda ash prices may still face downward pressure in the short term [8]. 3. Summary by Relevant Catalogs 3.1 Futures Market - On June 25, 2025, for the soda ash 2508 contract, the latest price was 1171, up 3 with a 0.26% increase, the open interest was 11699, down 29, and the trading volume was 2655. Its opening price was 1166, the highest was 1173, the lowest was 1159, and the settlement price was 1166 [4]. - For the soda ash 2509 contract, the latest price was 1166, up 1 with a 0.09% increase, the open interest was 1561404, down 7874, and the trading volume was 953401. Its opening price was 1158, the highest was 1168, the lowest was 1152, and the settlement price was 1160 [4]. - For the soda ash 2601 contract, the latest price was 1159, up 2 with a 0.17% increase, the open interest was 557916, up 2848, and the trading volume was 125828. Its opening price was 1150, the highest was 1160, the lowest was 1146, and the settlement price was 1154 [4]. 3.2 Spot Market On June 25, domestic soda ash enterprises' quotes remained at a low level. The mainstream ex - factory price of light soda ash was around 1250 - 1350 yuan/ton, and the mainstream delivered price of heavy soda ash to end - users was about 1300 - 1400 yuan/ton [4]. 3.3 Factors Affecting the Market - **Supply**: Since June, the weekly output of soda ash has remained above 700,000 tons, with significant supply pressure. Although some plants have maintenance plans in the medium - term approaching summer, there are few new maintenance plans in the short term, and the overall supply is at a high level [5]. - **Demand**: The involution in the photovoltaic glass industry has led to production cuts. The price rebound of float glass is based on the expectation of supply tightening. Whether the unplanned cold repairs are realized or not, it is unfavorable for the demand of soda ash. In addition, in the demand for light soda ash, the support from lithium carbonate and daily - use glass is limited, and the substitution ratio of caustic soda is less than 5%, with limited incremental demand. Overall, the demand recovery of downstream industries for soda ash is weak, and procurement is mostly for rigid needs, with a cautious market performance [5]. - **Macro - level**: There are signs of easing in the Middle East geopolitical conflict, and the overnight crude oil futures price has declined. Although the State Council executive meeting has made targeted arrangements for the real estate market recently, the year - on - year growth rate of real estate development investment is still declining without an obvious turning point, and its role in driving the demand for the glass industry downstream of soda ash is not clear [5][6].

Group 1 - The supply of soda ash remains in excess, requiring upstream low operating rates to maintain supply-demand balance, with high visible inventory levels in the midstream and upstream sectors [1][5] - Domestic soda ash is in a capacity expansion cycle, with new capacity of 2.5 million tons expected in 2024 and an additional 900,000 tons in the first quarter of 2025, leading to an overall effective capacity growth rate of approximately 5.6% by 2025 [2][4] - From August 2024, due to domestic soda ash surplus and declining prices, the export window has opened, with some producers actively exploring overseas markets, resulting in a net export status for soda ash [2][4] Group 2 - The float glass production is currently at a low level, with significant losses reported since July 2024, leading to an increase in cold repairs and a decrease in daily melting capacity from 170,000 tons to 158,000 tons [3] - The photovoltaic glass sector is experiencing a rebound, with daily melting capacity increasing to around 100,000 tons by the end of April 2025, although inventory levels are rising, which may hinder further increases [3] - Light soda ash demand growth is projected at 7.2% for 2024, but the growth rate for 2025 is expected to be lower at around 5.2%, with a year-on-year decline of 7.8% observed from January to April 2025 [3] Group 3 - The long-term outlook for soda ash remains oversupplied, with significant new production capacity planned for 2025, including 4.05 million tons from various producers [4] - The current high levels of visible inventory in the upstream sector indicate that while there may be short-term rebounds, sustained low operating rates will be necessary to maintain balance [5] - The forecasted operating rate for 2025 is approximately 83.7%, down from 86.4% in 2024, indicating a continued oversupply situation for soda ash [4]

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - The macro - situation has improved with the Sino - US talks making progress and the NDRC improving the long - term mechanism for private enterprises to participate in major national projects and planning to launch high - quality projects worth about 3 trillion yuan. For glass, on the supply side, the profit of glass made from natural gas, coal, and oil has slightly increased due to falling raw material costs, and production remains stable. On the demand side, downstream purchasing enthusiasm is average, and enterprise inventories have increased. The futures price is approaching the production cost, so cost support may work in the short term. For纯碱, the supply is decreasing slightly with some equipment maintenance, and downstream demand is lukewarm with more wait - and - see sentiment and small - scale destocking.
