1. Report Industry Investment Rating - The report provides a mid - term outlook for each variety, with most rated as "oscillating". The rated varieties include steel, iron ore, scrap steel, coke, coking coal, glass, soda ash, ferrosilicon, and silicomanganese [7][8][9][10][11][13][14] 2. Core View of the Report - The black building materials market has strong supply contraction expectations and continues to show a relatively strong trend. Although the fundamentals have not changed significantly and inventory pressure is not high, factors such as upcoming production restrictions and potential macro - positive news may drive price increases. After the market rallies to a high level, volatility increases, and it is recommended to wait and avoid risks. Future focus should be on policy implementation and terminal demand [1][6] 3. Summary by Variety Iron Element (Iron Ore) - Overseas mine shipments increased month - on - month, and the arrival volume at 45 ports decreased. Steel mill profitability increased, but iron water production decreased in some areas due to rainfall. Iron ore inventories at 45 ports, berthing areas, and factories decreased. With high demand and inventory reduction, the price is expected to oscillate after a slight decline [2] Carbon Element (Coking Coal and Coke) - **Coking Coal**: Overall supply is temporarily stable. Mongolian coal imports at the Ganqimaodu port reached a high this year. Coke production is stable, and coking coal demand is strong. Although the spot market sentiment has cooled, upstream mines are still reducing inventory. Future attention should be paid to regulatory policies, mine resumption, and Mongolian coal imports [2] - **Coke**: The price has been continuously raised, and the cost support for manganese silicon has been strengthened. The manganese ore market is in a wait - and - see state, and port ore prices remain firm. The downstream demand for manganese silicon is resilient, but the supply - demand relationship may become looser. The supply - demand relationship of ferrosilicon is healthy, and both are expected to oscillate [3] Alloys (Manganese Silicon and Ferrosilicon) - **Manganese Silicon**: The cost support is strengthened due to the continuous increase in coke prices. The downstream demand is resilient, but the supply - demand relationship may become looser. The price is expected to oscillate in the short term [3] - **Ferrosilicon**: Production may increase rapidly, and downstream demand is resilient. The supply - demand relationship is healthy, and the price is expected to oscillate in the short term [3] Glass - In the off - season, demand declines, deep - processing orders decrease, and inventory days increase. The supply is expected to remain stable, and the market is mainly affected by sentiment. It is expected to oscillate widely in the short term and decline in the long term [3][11] Soda Ash - The supply surplus situation remains unchanged. After a rapid short - term price decline, it is expected to oscillate. In the long term, the price center will decline to promote capacity reduction [6][11] Steel - Affected by coking coal supply disturbances, the futures market is strong. Spot trading is average, and inventory is accumulating. With low inventory and potential production restrictions, the fundamentals may improve, and the price is likely to rise. Future focus should be on production restrictions and terminal demand [7] Scrap Steel - Steel mill arrivals have decreased, and the spot price has risen slightly. Supply and demand are both strong, and the price is expected to follow the trend of finished steel [8]

Core Viewpoint - The price of soda ash has stabilized since late July, with market dynamics shifting towards a supply increase and weaker macro expectations, leading to a forecast of a weak price trend in the short term [1] Supply Dynamics - Domestic soda ash market is experiencing weak supply and demand, with a weekly production of 699,800 tons as of July 31, a decrease of 24,000 tons or 3.32% from the previous week [1] - Several soda ash production facilities are set to resume operations in early August, which may lead to an increase in production to approximately 733,600 tons per week [1] - New production capacity exceeding 2 million tons has been added this year, with an additional 3.5 million tons planned for the second half of the year, indicating potential future supply pressure [1] Inventory Trends - As of July 31, total inventory of domestic soda ash manufacturers decreased to 1.7958 million tons, a decline of 3.69% [2] - The reduction in inventory is attributed to a shift from manufacturer stock to trader warehouses rather than an increase in actual market consumption [2] - Social inventory has increased, indicating that supply pressure may rise as production capacity is gradually released [2] Price Pressure - Recent trading activity has seen new orders for soda ash increase by 50 to 150 yuan, but weak downstream demand has led to a cautious market sentiment [3] - The main contract price for soda ash futures on August 3 closed at 1,247 yuan, down 161 yuan or 11.43% from July 24 [3] - Analysts predict that the soda ash market will continue to operate under pressure due to weak downstream demand, with price estimates ranging from 1,220 to 1,300 yuan [3] Demand Conditions - Overall demand for soda ash remains weak, particularly due to declining production in the photovoltaic glass sector, which affects soda ash usage [4] - The construction sector, a key application area for soda ash through float glass, has seen a 20% year-on-year decline in new housing starts, limiting future demand growth [4] - The profitability of photovoltaic glass is currently negative, further constraining demand for soda ash in the short term [5]

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The fundamental situation of soda ash shows strong supply and weak demand, and the sentiment of policy benefits has faded. In the short term, it is expected to mainly fluctuate weakly [2]. - The main logic is that the supply of soda ash is at a high level, the terminal demand is declining, the inventory is at a high level in the same period, and the mismatch between supply and demand in the industry has not been effectively improved [5]. 3. Summary by Relevant Catalogs 3.1 Soda Ash Futures Market - The closing price of the main contract of soda ash futures was 1,271 yuan/ton, a rise of 1.44% from the previous value; the low - end price of heavy soda ash in Shahe was 1,250 yuan/ton, a rise of 0.81%; the main basis was - 21 yuan/ton, a rise of 61.54% [6]. 3.2 Soda Ash Spot Market - The low - end price of heavy soda ash in the Hebei Shahe market was 1,250 yuan/ton, up 10 yuan/ton from the previous day [12]. 3.3 Fundamental - Supply - The production profit of heavy soda ash has rebounded from a historical low, with a profit of - 22.90 yuan/ton for the North China ammonia - soda process and 56.50 yuan/ton for the East China co - production process [15]. - The weekly industry operating rate of soda ash was 80.27%, and the operating rate is expected to decline seasonally. The weekly output was 69.98 tons, with 39.87 tons of heavy soda ash, and the output was at a historical high [18][20]. - From 2023 to 2025, there were large - scale new production capacity plans for soda ash, with 640 tons in 2023, 180 tons in 2024, and a planned 750 tons in 2025 (actual production of 100 tons) [21]. 3.4 Fundamental - Demand - The weekly production and sales rate of soda ash was 109.83% [24]. - The daily melting volume of national float glass was 15.96 tons, and the operating rate was stable at 75% [27]. - The price of photovoltaic glass continued to fall. Affected by the "anti - involution" policy, the industry cut production, and the daily melting volume in production decreased significantly [30]. 3.5 Fundamental - Inventory - The national soda ash inventory in factories was 179.58 tons, a decrease of 3.69% from the previous week, and the inventory was running above the five - year average [33]. 3.6 Fundamental - Supply - Demand Balance Sheet - The report provided the annual supply - demand balance sheet of soda ash from 2017 to 2024E, including data such as effective production capacity, output, operating rate, imports, exports, net imports, apparent supply, total demand, supply - demand difference, capacity growth rate, output growth rate, apparent supply growth rate, and total demand growth rate [34]. 3.7 Influencing Factors - **Positive factors**: The peak summer maintenance period is approaching, and production will decline [3]. - **Negative factors**: Since 2023, the production capacity of soda ash has expanded significantly, and there are still large production plans this year; the downstream photovoltaic glass of heavy soda ash has cut production, and the demand for soda ash has weakened; the sentiment of the "anti - involution" policy has faded [5].

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The overall atmosphere in the commodity market remained weak yesterday, with the prices of finished products showing a weak and volatile trend. Although the short - term market sentiment has improved, the overall fundamentals are still weak, and the futures prices may gradually return to the real - trading logic. The current static fundamental contradictions are not obvious, and the Politburo meeting has no new statements on real estate, so the policy direction is expected to continue the previous strict control of incremental trends. Attention should be paid to the actual repair rhythm of terminal demand and the support strength of the cost side for finished product prices [3]. - The price of iron ore may fluctuate with the prices of downstream products and mainly show a volatile trend. The supply growth is limited, and the port inventory is trending downward. The demand support still exists, but the market divergence remains, and risk control is necessary [6]. - For manganese silicon and ferrosilicon, it is recommended that investment positions mainly adopt a wait - and - see approach, while hedging positions can seize opportunities according to their own situations. In the long - term, both may face the situation of weakening marginal demand [9][10]. - The price of industrial silicon may be weak in the short term, and the price of polysilicon may show a high - level volatile trend. The price increase chain of polysilicon needs to be further observed whether it can be smoothly transmitted to the downstream [14][15]. - The prices of glass and soda ash are expected to be volatile in the short term. For glass, if there are substantial real - estate policies, the futures price may continue to rise; for soda ash, it is recommended to wait and see in the short term and look for short - selling opportunities in the long term [17][18].
