Report Industry Investment Rating - Not provided in the given content Core Views - The alloy market shows a pattern of increasing supply and demand. However, the recent rapid increase in supply and limited further growth in demand suggest potential weakening in the supply - demand balance. Iron alloys can be considered as short - side allocation in the industrial chain [5]. - As the "anti - involution" trading calms down, commodity performance is expected to diverge. Products with actual production cuts and policy support will likely remain strong, while others will be driven more by their own fundamentals [5]. Summary by Directory Chapter 1: Comprehensive Analysis and Trading Strategies Comprehensive Analysis - **Supply**: The production of ferrosilicon and silicomanganese continued to rise this week, and the operating rates in recent weeks have shown an accelerating upward trend [5]. - **Demand**: The molten iron output of 247 steel mills slightly increased, but the apparent demand for steel, especially for rebar, decreased more than seasonally. Combined with the poor macro data in July, there is a risk of a decline in the demand side [5]. - **Cost**: The electricity price remained stable this week, and the price of port manganese ore increased slightly [5]. - **Market sentiment**: "Anti - involution" leading varieties such as polysilicon and coking coal are oscillating at high levels. As the "anti - involution" trading calms down, commodity performance will diverge. Iron alloys' supply - demand is currently stable but may face pressure from the accelerating supply increase [5]. Trading Strategies - **Single - side trading**: Due to the recent accelerating increase in supply, iron alloys can be used as short - side allocation in the industrial chain [6]. - **Arbitrage**: When the basis is low, cash - and - carry arbitrage can be considered [6]. - **Options**: Hold a wait - and - see attitude [6].

Report Date - The report is dated August 15, 2025 [1] Report Industry Investment Rating - No investment rating is provided in the report Core Views - **Steel**: After the coal mine safety meeting, the hype sentiment for coking coal cooled, leading to a correction in the black sector. This week, the supply of the five major steel products increased while demand decreased, and inventory accumulation accelerated. The fundamentals of steel are weakening, but overall inventory is low, and there is support from low - price buyers. The short - term market optimism has cooled, and the upper resistance for the rebar October contract is between 3250 - 3300. However, due to the expected supply contraction, the downside space is limited, with support at around 3100 for the rebar October contract (around 3350 for hot - rolled coils). The short - term disk is expected to be oscillating weakly [3] - **Iron Ore**: Market supervision has tightened, and speculative sentiment has declined. The price of iron ore was dragged down by the sharp drop in coking coal. The fundamentals of iron ore are currently stable, with short - term supply being neutral and iron - making water production expected to remain stable. Production restrictions have a limited impact on near - month demand. Steel mill profits are expected to remain at a good level, supporting the price. The price is expected to be in a range - bound pattern [19] - **Coking Coal and Coke**: There have been frequent reports of supply disruptions in Shanxi coal mines. The "anti - involution" in the coal industry will be the trading focus in the third quarter. However, the incremental substitution effect of imports cannot be ignored. The supply - demand of coking coal has returned to a tight - balance pattern. The long - term outlook for coking coal and coke is not pessimistic, and attention should be paid to macro - risk events [29] - **Ferroalloys**: The price trend of ferroalloys mainly follows the price fluctuations of coal. Currently, steel mill profits are good, and high iron - making water production supports ferroalloy demand. In the long term, the real - estate market is sluggish, and the support from the home appliance and automotive industries depends on policy stimulus. The supply of manganese ore is relatively sufficient, and the support from the ore end for ferromanganese is weak. In the short term, the "anti - involution" trading sentiment has subsided, but the market still has expectations for supply - side contraction [46] - **Soda Ash**: The supply of soda ash is expected to remain high, with daily production fluctuating around 106,000 - 107,000 tons. The demand for soda ash is expected to remain weak, and the upper - middle stream inventory has reached a new high, putting pressure on the spot price. The cost has increased slightly with the strong coal price. The pattern of strong supply and weak demand remains unchanged [56] - **Glass**: The near - term trading has returned to industrial reality, and policy expectations may fluctuate. The daily melting volume of the supply side is stable at around 159,000 - 160,000 tons. The cumulative apparent demand for glass has declined by 7%. The market is in a weak - balance state. The downstream inventory is at a high level, and the spot price is under pressure. Attention should be paid to policy guidance and short - term sentiment changes [82] Summary by Related Catalogs Steel - **Futures Prices**: On August 15, 2025, the closing price of the rebar 01 contract was 3269 yuan/ton, the 05 contract was 3314 yuan/ton, and the 10 contract was 3188 yuan/ton.

The overall wind direction change of the commodity market should be noted [2] - The iron ore futures price is expected to oscillate at a high level, with limited fundamental contradictions currently [3] - The coke futures price has a high short - term volatility, with the price being greatly affected by the "anti - involution" policy expectations [4] - The coking coal futures price has a large short - term volatility, and the price is greatly affected by the "anti - involution" policy expectations [6] - The silicon manganese price bottom is gradually rising, and the price is greatly affected by the "anti - involution" policy expectations, mainly following the coking coal trend [7] - The silicon iron price is mainly affected by the "anti - involution" policy expectations and follows the silicon manganese trend [8] Summary by Industry Steel - This week, the apparent demand for thread decreased significantly, production declined slightly, and inventory accumulation accelerated. The apparent demand for hot roll improved, production increased slightly, and the inventory accumulation rhythm slowed down [2] - The molten iron production declined moderately but remained at a high level. With low inventory, the market negative feedback pressure is not large. As the parade approaches, attention should be paid to the production restriction intensity in Tangshan and other places [2] - From the downstream industries, real estate investment continued to decline significantly, infrastructure growth slowed down, the manufacturing prosperity degree slowed down, and the overall domestic demand was still weak, while steel exports remained at a relatively high level [2] Iron Ore - On the supply side, the global iron ore shipment is stronger year - on - year, and there is an expectation of seasonal recovery in the future. The domestic port inventory has stabilized and rebounded, and there is no obvious inventory accumulation pressure even under high port clearance [3] - On the demand side, this week's steel apparent demand declined, but the proportion of profitable steel mills is at a high level, and currently there is insufficient motivation for active production reduction. Iron ore demand is still supported by high molten iron. Future attention should be paid to the progress of policy - based production restrictions [3] - At the macro level, the Sino - US tariff extension, domestic demand still needs policy support, and the market sentiment has cooled down due to the coking coal position limit [3] Coke - The coking plants in East China have expectations of production restrictions again as a major event approaches. The sixth round of coke price cuts has been implemented, profits have improved, and daily coke production has increased slightly [4] - The overall coke inventory is in a downward trend, and the purchasing willingness of traders is good. The supply of carbon elements is abundant, and the downstream molten iron remains at a high level in the off - season. The market sentiment has been boosted by coal over - production inspection [4] Coking Coal - The new version of the "Coal Mine Safety Regulations" mainly pushes up the cost per ton of coal. The production of coking coal mines has decreased, the spot auction market has improved, the transaction price has mainly increased, and the terminal inventory has remained flat [6] - The total coking coal inventory has decreased month - on - month, and the production - end inventory has continued to decline significantly. It is likely to continue de - stocking in the short term. The supply of carbon elements is abundant, and the downstream molten iron remains at a high level in the off - season. The market sentiment has been boosted by coal over - production inspection [6] Silicon Manganese - The demand side has a molten iron production of over 240, still maintaining a high level. The weekly silicon manganese production has continued to increase, but the production increase rate is lower than expected, providing some support for the price [7] - The manganese ore price has increased slightly this week. It is judged that the manganese ore will mainly accumulate inventory in the second half of the year. In July, supply exceeded demand, and the on - balance - sheet inventory continued to be depleted. Attention should be paid to when the on - balance - sheet silicon manganese inventory starts to increase [7] Silicon Iron - The molten iron production has decreased slightly but remained above 240. A large northern steel mill's tender price increased by 430 compared with the previous round, with a tender price of 6030 yuan/ton and an inquiry price of 5700 yuan/ton [8] - The export demand remains at about 30,000 tons, with a marginal impact being small. The metal magnesium production has decreased slightly month - on - month, and the secondary demand has declined marginally. The overall demand is acceptable [8] - The silicon iron supply has increased significantly, the market transaction level is average, and the on - balance - sheet inventory has increased slightly [8]

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]
