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]

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The short - term macro environment for steel is positive, with supply contraction expectations, stable cost support, and the steel futures market may show a volatile and upward - biased pattern. The long - term trend depends on the actual demand during the peak season [3]. - Iron ore prices are bounded, with short - term stable fundamentals and long - term focus on hot - rolled coil inventory pressure. The current oscillation needs macro changes to break [20]. - For coal and coke, although there are import substitution effects, considering policy expectations and support for finished product prices, the medium - to - long - term trend is not pessimistic [29]. - The price of ferroalloys follows coal price fluctuations. In the short - term, there are still expectations of supply contraction, and in the long - term, demand support may weaken [45]. - The supply of soda ash exceeds demand, with high inventory and weak demand. Attention should be paid to cost fluctuations and price cuts by alkali plants [55]. - The glass market is in a weak balance, with high intermediate inventory and weak sales. Attention should be paid to policy guidance and short - term sentiment changes [80]. Summary by Directory Steel - **Supply**: Coal mine over - production governance and the "276 - working - day" policy support costs. There are expectations of supply contraction due to restrictions during the Tangshan parade [3]. - **Demand**: Steel export orders have improved slightly, but the price inversion still exists. The market depends on the actual demand during the peak season [3]. - **Price Data**: On August 13, 2025, the closing prices of steel futures contracts such as rebar and hot - rolled coil decreased compared to the previous day.
