1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Nickel: Under the fundamental logic, it fluctuates in a narrow range, and the long - term logic is under pressure. However, there are frequent events in Indonesia, so be vigilant against the risk of news - driven stimulation [4]. - Stainless steel: The pressure at the real - end still needs to be continuously alleviated, and the steel price fluctuates [5]. - Industrial silicon: Pay attention to the resumption rhythm of upstream factories [34]. - Polysilicon: There will be more event disturbances next week. The main idea is to go long on dips [35]. - Lithium carbonate: Supply is weak while demand is strong, and the price is strengthening [56]. 3. Summaries According to Related Catalogs Nickel - **Fundamentals**: The marginal operation of the fundamentals is relatively stable. The global refined nickel's visible inventory shows a gentle increase, dragging down the upper limit of nickel prices. The long - term low - cost supply increment may change the cost curve pattern. In the short - term and the second half of the year, the nickel price valuation may be at the window boundary of the ferronickel conversion path. The inventory at the ferronickel link has slightly decreased, slightly boosting the upper limit of the nickel price, but the amplitude is limited. The overall decline of the ore price is relatively mild, and the support has weakened slightly, but it is still difficult for the price to fall sharply. The hype of nickel ore contradictions may decrease, limiting the elasticity of nickel prices [4]. - **Market News Impact**: Indonesia may crack down on illegal mining, change the RKAB approval cycle, and re - evaluate the nickel ore HPM formula. These events increase the risk of short - selling at low levels and add uncertainty to the nickel price [4]. - **Inventory Changes**: China's refined nickel social inventory increased by 1,963 tons to 41,286 tons. LME nickel inventory decreased by 570 tons to 211,662 tons [6][7]. Stainless Steel - **Fundamentals**: The pressure at the real - end still needs to be continuously alleviated. The long - side logic focuses on the decline of inventory at a high level, the reduction of factory inventory pressure in July, and the potential reduction in supply due to policy tightening. The short - side logic comes from the actual supply - demand situation, where the alleviation of pressure needs to be continuous, and the supply elasticity may limit the upside [5]. - **Inventory and Production**: Social inventory has declined slightly for five consecutive weeks, and the factory inventory pressure in July has decreased. The stainless steel production in August is 3.25 million tons, with a marginal increase. The production in Indonesia in August is 420,000 tons [5]. Industrial Silicon - **Price Trend**: The industrial silicon futures fluctuated this week, and the spot price increased. The futures price first rose, then fell, and then rose again, influenced by other varieties and macro - sentiment. The spot prices in Xinjiang and Inner Mongolia increased [30]. - **Supply - Demand Fundamentals**: On the supply side, the weekly industry inventory decreased slightly. Factories in the southwest and northwest regions had some resumptions, but the rhythm was slow. On the demand side, the short - term demand of downstream industries increased marginally, with the polysilicon and organic silicon sectors supporting consumption [31][32]. - **Market Outlook**: Pay attention to the resumption rhythm of upstream factories. Before a large - scale resumption, the futures price may follow the coking coal futures, but the long - term fundamental direction is bearish. It is recommended to short at high levels and take profits at low levels [34]. Polysilicon - **Price Trend**: The polysilicon futures fluctuated widely this week, showing a relatively strong trend overall. The spot market had some transactions, but the price did not show obvious improvement [30]. - **Supply - Demand Fundamentals**: The short - term weekly production remained at a high level, and the upstream inventory increased. The demand from the silicon wafer side improved, and the production in August increased slightly compared with July [32][33]. - **Market Outlook**: There will be more event disturbances next week. The main idea is to go long on dips. The spot market's signing is approaching the end, and the terminal demand may decrease in September. It is recommended to take profit on the PS2511 - PS2512 inter - period positive spread and maintain the inter - period reverse spread idea [35]. Lithium Carbonate - **Price Trend**: The lithium carbonate futures price increased significantly, and the spot price also rose. The SMM basis and the spread between contracts changed accordingly [54]. - **Supply - Demand Fundamentals**: On the supply side, production in Jiangxi and Qinghai was affected, and there were concerns about future production. On the demand side, the downstream production demand in August improved significantly. The social inventory decreased slightly, and the number of futures warrants increased [55]. - **Market Outlook**: Due to supply disturbances, the lithium price is expected to remain strong for about a month. If the downstream demand in September strengthens, the price will continue to be strong. The futures main contract price is expected to range from 85,000 to 95,000 yuan/ton [56][57].

New furnaces were opened in Xinjiang, Sichuan, Gansu, and Ningxia. The SMM industrial silicon social inventory decreased by 0.20 million tons, and the sample factory inventory increased by 0.11 million tons. Xinjiang's large factories have further复产 plans. Considering the remaining time of the wet season, the later - stage increase in southern production is limited. Downstream maintains rigid demand procurement. In July, the industrial silicon balance sheet showed a de - stocking of about 30,000 tons. In August, the supply side is expected to have a marginal increase of about 40,000 tons, but due to the large - scale复产 of polysilicon, industrial silicon may still de - stock [12] 3.2.2 Organic Silicon - This week, the price of organic silicon fluctuated downward. The production load of monomer factories remained stable. Hesheng's Sichuan plant plans to resume production. The overall enterprise operating rate was 77.7%, the weekly output was 51,400 tons, a 0.39% increase, and the inventory was 48,500 tons, a 2.97% increase.

The price of centralized projects showed signs of loosening, and the distributed spot price was temporarily stalemate. The production schedule is 45GW. Overseas demand decreased due to the possible policy extension. Domestic centralized power stations are still waiting and watching. The market logic may put pressure on component prices, and policy support is needed [16] 3.3 Investment Recommendations 3.3.1 Industrial Silicon - Based on the reality of Xinjiang's large factories'复产 falling short of expectations and the large - scale increase in polysilicon production, the fundamentals of industrial silicon have improved and are in a de - stocking state. However, considering the future复产 of large factories and polysilicon production cuts, the fundamentals are not optimistic. In the short term, a strategy of buying on dips is recommended, with the risk being the large factories'复产 [3][17] 3.3.2 Polysilicon - The fundamentals are bearish for the market. Middle - section deliverable enterprises are actively hedging, and more warehouse receipts will be registered. The market has strong speculative properties and is supported at 49,000 yuan/ton. In the short term, the price may range from 45,000 - 57,000 yuan/ton, and in the long term, it is expected to exceed 60,000 yuan/ton. A strategy of bullish on pullbacks is recommended, and attention can be paid to the 11 - 12 reverse arbitrage opportunity at about - 2000 yuan/ton [4][18] 3.4 Hot News - The US launched anti - dumping and counter - vailing investigations on crystalline silicon photovoltaic cells imported from India, Indonesia, and Laos.

Group 2: Supply and Demand Outlook - The core contradiction in the polysilicon market is the limited actual transaction volume despite rising prices, with strong supply and weak demand persisting [3]. - There are expectations of supply contraction due to potential production limits announced for September, which could lead to a decrease in polysilicon output [3]. - The market is currently influenced by strong expectations of policy changes, with a key meeting scheduled for August 19 that may impact market sentiment and pricing [3]. Group 3: Future Price Trends - The short-term price trajectory of polysilicon is highly dependent on the strength and timing of policy signals, with the next month being critical for potential policy implementation [4]. - If the path for capacity reduction becomes clear, prices may continue to rise; however, if policy measures fall short of expectations, market sentiment may decline, leading to a potential price drop [4]. - Currently, the driving forces for price movement in both directions are weak, suggesting that polysilicon prices may remain in a high-level fluctuation pattern in the near term [4].

Core Viewpoint - The photovoltaic industry, particularly polysilicon, is at the center of the current "anti-involution" trend, with significant attention on capacity consolidation efforts among leading polysilicon manufacturers [1][2] Group 1: Industry Developments - A recent chat screenshot indicates that polysilicon companies may limit monthly output and sales starting September, with a total annual capacity cap of 2 million tons for 2026 [1] - The initial plan for capacity consolidation involves the top six polysilicon manufacturers, including Tongwei Co., GCL-Poly Energy, and others, aiming to acquire remaining production capacities [2] - In July, polysilicon prices rose significantly, with n-type re-investment material prices increasing from 34,400 yuan/ton in late June to 47,400 yuan/ton by mid-August, marking a nearly 37.8% increase [2] Group 2: Market Dynamics - The domestic polysilicon production is expected to reach approximately 125,000 tons in August and potentially 140,000 tons in September, contributing to an increase in inventory levels [3] - Current price increases are largely driven by market sentiment rather than fundamental supply-demand changes, with a warning that excessive price hikes could lead to downstream losses and reduced demand [3][4] - The industry needs to establish a balance where all segments avoid losses, which may require a long-term commitment to reducing output and managing inventory effectively [4]

Group 1: Report Overview - Date: August 15, 2025 [2] - Report Type: Polysilicon Daily Report - Research Team: Energy and Chemical Research Team [3] Group 2: Market Performance and Outlook Market Performance - The price of the polysilicon main contract continued to show high - level fluctuations. The closing price of PS2509 was 50,430 yuan/ton, with a decline of 3.08%. The trading volume was 415,544 lots, and the open interest was 127,757 lots, a net decrease of 4,706 lots [4] Market Outlook - There is no policy follow - up in the polysilicon market, and the sentiment of capital gambling on policy expectations has cooled. The spot average price (re - feeding material) is stable at 47,500 yuan/ton, which is supported by the previous anti - involution policy and provides a rigid support for the lower side of the market. The increase in the price of the industrial chain has led to a simultaneous increase in production, and the supply - demand contradiction is not intensified. However, the price increase has not been smoothly transmitted to components and end - users. From a policy perspective, high - price products are not conducive to achieving the dual - carbon goal. In August, polysilicon production increased significantly to 125,000 tons, which can meet the downstream cell demand of about 56GW. The monthly output of silicon wafers and cells decreased to about 52GW, and the overall supply - demand pattern remains loose. Overall, the futures and spot prices are rigidly supported by policies, and the market will mainly maintain wide - range fluctuations [4] Group 3: Market News - On August 14, the number of polysilicon warehouse receipts was 5,480 lots, a net increase of 330 lots compared with the previous trading day. From January to June, the cumulative photovoltaic installed capacity was 212.21GW, a year - on - year increase of 107.07%; in June, the domestic installed capacity was only 14GW. According to customs data, in June 2025, China exported about 21.7GW of photovoltaic modules, a month - on - month decrease of 3% and a 2% decrease compared with 22.1GW in June 2024. From January to June, the cumulative export of photovoltaic modules was about 127.3GW, a 3% decrease compared with the same period last year [5]

Group 1: Report Overall Information - The report is the Black Building Materials Daily on August 15, 2025, covering various black building materials such as steel, iron ore, manganese silicon, ferrosilicon, industrial silicon, polysilicon, glass, and soda ash [1] Group 2: Steel Futures Market - The closing price of the rebar main contract in the afternoon was 3189 yuan/ton, down 33 yuan/ton (-1.02%) from the previous trading day. The registered warehouse receipts on that day were 109,055 tons, a month - on - month increase of 2382 tons. The position of the main contract was 1.636544 million lots, a month - on - month decrease of 16,049 lots [2] - The closing price of the hot - rolled coil main contract was 3432 yuan/ton, down 19 yuan/ton (-0.55%) from the previous trading day. The registered warehouse receipts on that day were 78,386 tons, with no month - on - month change. The position of the main contract was 1.291831 million lots, a month - on - month decrease of 62,005 lots [2] Spot Market - The aggregated price of rebar in Tianjin was 3320 yuan/ton, a month - on - month decrease of 30 yuan/ton; the aggregated price in Shanghai was 3320 yuan/ton, a month - on - month decrease of 40 yuan/ton [2] - The aggregated price of hot - rolled coils in Lecong was 3450 yuan/ton, a month - on - month decrease of 30 yuan/ton; the aggregated price in Shanghai was 3450 yuan/ton, a month - on - month decrease of 20 yuan/ton [2] Market Analysis - The overall atmosphere in the commodity market was weak yesterday, and the prices of finished products showed a weak and volatile trend. This week, the export volume declined slightly, and the overall export remained weak [3] - In terms of fundamentals, the demand for rebar decreased significantly this week, production was basically the same as last week, and the inventory accumulation rate increased. For hot - rolled coils, demand rebounded significantly, production was basically the same as last week, and the inventory accumulation rate slowed down. Currently, the inventories of both rebar and hot - rolled coils are on the rise marginally, steel mills' profit levels are good, and production remains high, but the demand side's ability to absorb is obviously insufficient [3] - With the Politburo meeting concluded and the "anti - involution" sentiment gradually cooling down, market sentiment has become more rational, and the futures price trend has started to weaken. If the subsequent demand cannot be effectively repaired, steel prices may not be able to maintain the current level, and the futures price may gradually return to the supply - demand logic [3] Group 3: Iron Ore Futures Market - Yesterday, the main contract of iron ore (I2601) closed at 775.00 yuan/ton, with a change of - 2.52% (-20.00), and the position changed by - 462 lots to 452,000 lots. The weighted position of iron ore was 907,500 lots [5] Spot Market - The price of PB fines at Qingdao Port was 771 yuan/wet ton, with a basis of 44.12 yuan/ton and a basis rate of 5.39% [5] Market Analysis - In terms of supply, the latest overseas iron ore shipments and arrivals both decreased. On the shipment side, shipments from Australia continued to decline month - on - month due to mine maintenance, shipments from Brazil increased month - on - month, and shipments from non - mainstream countries decreased slightly month - on - month [6] - In terms of demand, the latest daily average pig iron output according to Steel Union data was 2.4066 million tons, a month - on - month increase of 0.34 million tons, mainly due to the increase in the utilization rate of the production capacity of previously restarted blast furnaces [6] - In terms of inventory, port inventories increased slightly, and steel mills' imported ore inventories increased significantly. Terminal data showed that the apparent demand for the five major steel products continued to weaken this week, and the decline in rebar consumption data was obvious [6] - From a fundamental perspective, the current supply side is in the traditional shipment off - season for overseas mines, and the pressure is not significant. The profitability rate of steel mills has started to decline after raw material prices reached a relatively high level. Due to the slight weakening of terminal demand, the short - term upward increase in pig iron may be limited [6] Group 4: Manganese Silicon and Ferrosilicon Futures Market - On August 14, the main contract of manganese silicon (SM509) fluctuated weakly, closing down 0.40% at 6050 yuan/ton. The spot price of 6517 manganese silicon in Tianjin was 5950 yuan/ton, with a basis of 90 yuan/ton [8] - The main contract of ferrosilicon (SF509) continued to weaken, closing down 0.86% at 5744 yuan/ton. The spot price of 72 ferrosilicon in Tianjin was 5900 yuan/ton, with a basis of 156 yuan/ton [8] Market Analysis - From a daily - line perspective, the futures price of manganese silicon is still above the short - term rebound trend line since early June. It is recommended that investment positions remain on the sidelines, while hedging positions can still participate at the right time [9] - For ferrosilicon, the futures price is also above the short - term rebound trend line since early June. Similar to manganese silicon, investment positions are advised to wait and see, and hedging positions can participate as appropriate [9] - Since the Central Financial and Economic Commission's Sixth Meeting on July 1, the "anti - involution" trading has affected the market. As the sentiment of Supply - side 2.0 cools down, the market is squeezing out the over - valued part, driving prices down. Currently, sentiment still has a significant impact on the futures price [10] - In the short - term, it is not recommended that speculative funds participate excessively, and it is better to wait and see. However, hedging funds can seize hedging opportunities according to their own situations [10] - Fundamentally, the over - supplied industrial pattern of manganese silicon has not changed due to "anti - involution." For ferrosilicon, there has been no obvious change, and it is expected that in the future, there will be a marginal weakening of demand for manganese silicon, ferrosilicon, or the entire black sector [11] Group 5: Industrial Silicon and Polysilicon Industrial Silicon - Yesterday, the main contract of industrial silicon (SI2511) closed at 8675 yuan/ton, with a change of + 0.87% (+75). The weighted contract position changed by - 14,051 lots to 535,123 lots [13] - In the spot market, the price of 553 non - oxygen - permeable industrial silicon in East China was 9200 yuan/ton, with no month - on - month change, and the basis of the main contract was 525 yuan/ton; the price of 421 was 9750 yuan/ton, with no month - on - month change, and the basis of the main contract was 275 yuan/ton [13] - The futures price of industrial silicon is expected to fluctuate weakly in the short term. The problems of over - capacity, high inventory, and insufficient effective demand have not fundamentally changed. In August, the operating rate of industrial silicon is expected to increase, and downstream demand can provide some support, but new inventory pressure may occur [14] Polysilicon - Yesterday, the main contract of polysilicon (PS2511) closed at 50,430 yuan/ton, with a change of - 1.68% (-860). The weighted contract position changed by - 4414 lots to 310,109 lots [15] - In the spot market, the average price of N - type granular silicon according to SMM was 44.5 yuan/kg, with no month - on - month change; the average price of N - type dense material was 46 yuan/kg, with no month - on - month change; the average price of N - type re - feeding material was 47 yuan/kg, with no month - on - month change, and the basis of the main contract was - 3430 yuan/ton [15] - In July, "anti - involution" and the expectation of a polysilicon industry capacity integration plan drove prices up rapidly. In August, polysilicon is expected to increase production, and downstream silicon wafer production has increased to some extent, but silicon materials are likely to accumulate inventory. The price of downstream distributed components has increased and then回调, and whether the price increase chain in the industry can be smoothly transmitted to the end - user remains to be seen [16] Group 6: Glass and Soda Ash Glass - On Thursday, the spot price in Shahe was 1164 yuan, unchanged from the previous day; the spot price in Central China was 1120 yuan, also unchanged from the previous day. As of August 14, 2025, the total inventory of national float glass sample enterprises was 63.426 million weight boxes, a month - on - month increase of 1.579 million weight boxes (+2.55%), and a year - on - year decrease of 5.94%. The inventory days were 27.1 days, an increase of 0.7 days from the previous period [18] - After the Politburo meeting, market sentiment cooled down, and glass prices回调 significantly. Currently, the market sentiment has basically been digested. Glass production continues to increase, inventory pressure has increased, and downstream real - estate demand data has not improved significantly [18] - In the short term, glass is expected to fluctuate, and its valuation should not be overly underestimated. In the long term, glass prices will fluctuate with macro sentiment. If there are substantial policies in the real - estate sector, futures prices may continue to rise; otherwise, supply - side contraction is needed for significant price increases [18] Soda Ash - The spot price was 1280 yuan, a month - on - month increase of 20 yuan. As of August 14, 2025, the total inventory of domestic soda ash manufacturers was 1.8938 million tons, an increase of 17,600 tons (0.94%) from Monday. Among them, the inventory of light soda ash was 760,000 tons, a month - on - month increase of 18,700 tons, and the inventory of heavy soda ash was 1.1338 million tons, a month - on - month decrease of 1100 tons [19] - The downstream float glass operating rate increased slightly, and the photovoltaic glass operating rate decreased and then stabilized. Downstream buyers are waiting and seeing, and procurement enthusiasm has slowed down. Soda ash production facilities are operating stably, and inventory pressure has increased, but heavy - soda ash inventory has decreased slightly [19] - In the short term, soda ash prices are expected to fluctuate. In the long term, under the "anti - involution" logic, supply - side and market sentiment will have a greater impact on prices, and the price center is expected to gradually rise, but the room for price increases will be limited due to the slow improvement of downstream demand [19]
