1. Report Industry Investment Rating - The report does not explicitly provide an overall industry investment rating. However, the mid - term outlook for the black building materials industry is "oscillating" [6]. For individual products, most are rated as "oscillating", including iron ore, coke,焦煤, glass,纯碱, manganese silicon, and silicon iron [8][9][11][12][13][14][15][16][17][18]. 2. Core Viewpoints of the Report - After about a week of decline, the black building materials entered the lower end of the valuation range. With supply constraints on furnace materials and expectations of stricter safety supervision, prices rebounded significantly. As the off - peak and peak seasons are approaching, the apparent demand for steel remains weak, but it's not yet the time to verify terminal demand. With low inventory pressure in each link of the black industry chain and in the pre - peak season restocking window, prices are expected to have a small rebound space. Attention should be paid to future demand performance and furnace material supply recovery [2]. - Overall, after consecutive days of decline, black prices have fallen near the cost support level, and demand negatives have been gradually digested. With supply disturbances in furnace materials and downstream restocking demand, there is a driving force for price rebound. However, the weak expectation of peak - season terminal demand remains, suppressing the upside space. Future focus should be on policy implementation and terminal demand performance [6]. 3. Summary by Related Catalogs 3.1 Iron Element - Core Logic: Overseas mine shipments decreased month - on - month, and the arrival volume at 45 ports slightly declined, close to last year's level, with relatively stable total supply. On the demand side, pig iron production increased slightly, and the end - of - month production restrictions have limited impact, so iron ore demand is expected to remain high. In terms of inventory, the iron ore ports destocked this week, with a slight decrease in total inventory. There are limited bearish drivers in the fundamentals, and the price is expected to oscillate [3]. - Outlook: With high iron ore demand, stable supply and inventory, and limited bearish fundamental drivers, the price is expected to oscillate in the future [9]. 3.2 Carbon Element - Core Logic: Some coal mines in the production area have resumed production, but some are still restricted by accidents and other factors. For example, a 3 - million - ton low - sulfur lean primary coking coal mine in Xiangning, Linfen, Shanxi has been shut down for three days. On the import side, the average daily customs clearance at the Ganqimaodu Port remains above 1,000 vehicles, but there was a short - term decline in the past two days due to the Mongolian customs system. On the demand side, the eighth round of coke price increase has started again, showing regional differentiation. In some areas, coking production is restricted, and the short - term rigid demand for coking coal has slightly declined. Downstream enterprises mainly purchase on demand, and spot transactions have weakened. Some coal mines have started to accumulate inventory, but overall, there is no obvious inventory pressure. The short - term fundamental contradictions are not prominent, and the short - term disk still has support under a healthy fundamental situation [3]. - Outlook: With continuous supply disturbances and difficult significant supply increase before the parade, short - term fundamental contradictions are not prominent, and the short - term disk still has support under a healthy fundamental situation [13]. 3.3 Alloys 3.3.1 Manganese Silicon - Core Logic: Yesterday, the coking coal futures price rose significantly, and the black sector was strong, with manganese silicon oscillating strongly. Manganese silicon manufacturers stocked up on raw materials before the parade, and the restocking is nearly over. With increased arrivals and rising supply pressure, the port ore price has weakened from its high level. In terms of supply and demand, steel mills have good profits, and finished product output remains high. Under the environment of industry profit repair, the resumption of production by manufacturers continues, and the supply - demand relationship of manganese silicon may gradually become looser. In the medium - to - long - term, there may be downward pressure on the manganese silicon price [3]. - Outlook: Currently, the market inventory pressure is controllable, and the cost provides support, so the short - term downward space for the manganese silicon price is limited. But in the medium - to - long - term, as the supply - demand relationship becomes looser, the price may decline. Attention should be paid to the reduction in raw material costs [17]. 3.3.2 Silicon Iron - Core Logic: The current market inventory pressure of silicon iron is not large. In the short - term, the silicon iron price is expected to oscillate. However, in the future, the supply - demand gap will gradually be filled, and there are hidden concerns in the fundamentals. The upside space of the price is not optimistic. Attention should be paid to the dynamics of the coal market and the adjustment of electricity costs [3]. - Outlook: Currently, the market inventory pressure is not large, and the cost provides support, so the short - term downward adjustment space for the silicon iron price is limited. But the medium - to - long - term supply - demand outlook is pessimistic, and the price center is expected to move down. Attention should be paid to the coal market dynamics and the adjustment of electricity costs in the main production areas [18][20]. 3.4 Glass - Core Logic: After the glass futures price fell, the sentiment in the spot market declined, with mid - stream shipments and a significant decline in upstream production and sales. On the supply side, there is still one production line waiting to produce glass, and the overall daily melting volume is expected to remain stable. The upstream has slightly accumulated inventory, with no prominent self - contradictions but more market sentiment disturbances. Recently, the rising coal price has strengthened the cost support, but the fundamentals are still weak [3]. - Outlook: The actual demand is weak, but the policy expectation is strong, and the raw material price is strong. After the transaction of delivery contradictions, the far - month contract still gives a premium. In the medium - to - long - term, market - oriented capacity reduction is still needed, and if the price returns to fundamental trading, it is expected to oscillate downward [15]. 3.5 Steel - Core Logic: There are still contraction disturbances in the supply of coking coal and iron ore. Under the background of high pig iron production, the cost has an upward driving force, and the disk has strong support. The overall spot steel transactions are average, mainly at low prices, and the market sentiment is still cautious. Last week, the production of rebar decreased, and the production of hot - rolled coils increased. As the off - peak season ends, mid - and downstream enterprises are restocking before the parade. The apparent demand for rebar has improved month - on - month, and inventory accumulation has slowed down. The demand for hot - rolled coils remains highly resilient, and inventory continues to accumulate under high production. The supply - demand fluctuations of medium - thick plates and cold - rolled products are limited, with both supply and demand of the five major steel products increasing, and the inventory accumulation speed slowing down [8]. - Outlook: As the off - peak season ends, steel inventory continues to accumulate, and the market is still cautious about the peak - season demand. Both supply and demand will be affected before and after the parade. The blast furnace production restriction situation needs to be tracked, and there may be shutdowns of construction sites and factories in Beijing and surrounding areas. The pre - parade restocking of raw materials may end. Recently, there are continuous disturbances in the cost supply side. The short - term disk is expected to oscillate widely. Future focus should be on steel mill production restrictions and terminal demand performance [8]. 3.6 Coke - Core Logic: In the futures market, the eighth round of coke price increase has started again, combined with continuous rumors of production restrictions and strengthened cost support from coking coal, coke prices were strong yesterday. In the spot market, the quasi - first - grade coke price at Rizhao Port is 1480 yuan/ton (+10). On the supply side, the seventh round of price increases has been fully implemented, and coking enterprise profits have quickly recovered. As the parade approaches, coking production in some areas is gradually restricted, while others maintain normal production. On the demand side, downstream steel mills have good profits and are actively producing. Affected by the parade, transportation in some areas is restricted, so local steel mill inventories are still low, and some coking enterprises have started to accumulate inventory. Currently, the inventory of upstream coking enterprises is still at a low level, and under simultaneous production restrictions on coking and steel, the short - term supply - demand remains tight [12]. - Outlook: As the parade approaches, the expectation of coke production restrictions may be stronger than that of steel mills. The short - term tight supply situation will continue. With the start of the eighth round of price increases and strengthened cost support from coking coal, the short - term disk has strong support [12]. 3.7 Scrap Steel - Core Logic: The average tax - excluded price of crushed scrap in East China is 2174 (+5) yuan/ton, and the rebar - to - scrap price difference in East China is 1032 (+24) yuan/ton. In terms of supply, the arrival volume of scrap steel decreased month - on - month this week. In terms of demand, the profit of electric arc furnaces is low due to the pressure on finished products recently. The profit and loss of electric arc furnaces during off - peak electricity hours in East China is at a tight balance, and there are losses in many other areas during off - peak hours. The daily consumption of scrap steel in electric arc furnaces has decreased month - on - month. In the blast furnace sector, pig iron production has slightly increased, and the daily consumption of scrap steel in long - process production has also slightly increased. The total daily consumption of scrap steel in both long - and short - process production has increased slightly. In terms of inventory, the factory inventory has slightly increased, and the available inventory days have dropped to a relatively low level [10]. - Outlook: The fundamental contradictions of scrap steel are not prominent. The pressure on finished product prices has led to low electric arc furnace profits, but resources are still tight. The price is expected to oscillate in the short - term [10]. 3.8 Sodium Carbonate - Core Logic: The delivered price of heavy - quality sodium carbonate in Shahe is 1230 - 1280 yuan/ton (-). The domestic commodity market sentiment has improved, and as the delivery approaches, the fundamental logic returns, with a neutral macro - environment. On the supply side, the production capacity has not been cleared, and there is still long - term suppression. The production is at a high level, and supply pressure remains. There is no short - term disturbance to production, and production is expected to continue to increase. On the demand side, heavy - quality sodium carbonate is expected to maintain rigid - demand procurement. There are still ignition production lines that have not produced glass, the float glass daily melting volume is expected to be stable, and the daily melting volume of photovoltaic glass is expected to bottom out initially, currently at 86,500 tons. The demand for heavy - quality sodium carbonate is flat. In the light - quality sodium carbonate sector, downstream procurement is flat, but the overall downstream restocking sentiment is weak, and there is resistance to high prices. Sentiment affects the disk. As the shipping problem eases, mid - stream inventory accumulates, and downstream acceptance is weak [16]. - Outlook: The oversupply pattern remains unchanged. After the disk price drops, there is a small increase in spot - futures transactions. It is expected to oscillate widely in the future. In the long - term, the price center will continue to decline to promote capacity reduction [16].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report 2.1 Weekly Summary - PX prices fluctuated upward this week due to cost support. International oil prices showed a slight upward - fluctuating trend, and the domestic PX devices operated stably. The demand side of PTA performed well, and the polyester industry maintained high - level operation. Also, news of possible naphtha production cuts in South Korea and petrochemical industry policy news boosted the PX price [9]. - PTA prices went up due to cost support and unplanned device shutdowns. The news of possible naphtha production cuts in South Korea pushed up the PX market, which was beneficial to PTA. A 5 - million - ton PTA device in South China shut down unexpectedly, leading to inventory reduction from August to September. Traders were reluctant to sell, and the spot basis strengthened. Meanwhile, the polyester industry gradually increased its operation rate in anticipation of the peak demand season [9]. 2.2 Future Market Forecast - Strategy recommendation: Stay on the sidelines. - Crude oil: Geopolitical conflicts will increase market uncertainty, and the market will mainly choose to wait and see. Oil prices are expected to fluctuate widely. - PX: A total of 1.6 - million - ton PX devices in South China are planned to start operation successively this week. The rigid demand for spot purchases from newly - put - into - operation PTA devices will support PX demand. - PTA: A 2.2 - million - ton PTA device in East China will restart, but it cannot offset the impact of the shutdown of a 5 - million - ton PTA device in South China. In addition, the low processing fees of PTA continue, and there may be other unplanned device overhauls. - Polyester: There is no clear plan for polyester device overhauls next week. As the traditional peak demand season approaches, manufacturers' tolerance for inventory increases, and the market supply pressure of polyester factories will be low in the future. - Weaving: Demand is marginally improving, and there are expectations for the peak season. - Overall: PX will fluctuate strongly in the range of 6,850 - 7,050 yuan/ton; PTA will also fluctuate strongly in the range of 4,750 - 4,950 yuan/ton [11][12]. 3.

1. Report Industry Investment Rating No information provided in the report regarding the industry investment rating. 2. Core Viewpoints - The overall demand for steel products is weak, with the inventory accumulation rate accelerating, and the steel mills' profit is gradually shrinking. If the demand fails to improve effectively, the price may continue to decline. Attention should be paid to the potential impact of safety inspections and environmental protection restrictions [3]. - For iron ore, although the supply pressure is not significant during the traditional shipping off - season, the contradiction between high hot metal production and weak terminal demand needs attention. The price is expected to fluctuate strongly in the short term [6]. - For ferrous alloys, the prices are affected by emotions in the short term. It is not recommended for speculative funds to participate excessively. Hedging funds can seize opportunities according to their own situations. The fundamental problems of over - supply in manganese silicon and silicon iron still exist [10][11]. - For industrial silicon and polysilicon, industrial silicon is expected to fluctuate strongly, and polysilicon will maintain a pattern of "weak reality, strong expectation" and high - volatility operation [16][17]. - For glass and soda ash, glass is expected to fluctuate weakly in the short term, and soda ash is expected to fluctuate. In the long term, the price center of soda ash may gradually rise, but the upward space is limited [19][20]. 3.

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Views of the Report - The pure benzene market maintains a pattern of increasing supply and demand. The supply is driven by the stable operation of refineries and the recovery of hydrobenzene plants, while the demand shows a mixed performance. Overall, the short - term fundamentals have marginally improved, but the contradiction between high latent inventory and insufficient terminal demand remains [3]. - The styrene market rebounded with the cost in the short - term. However, the medium - term trend depends on the implementation of maintenance and the recovery of terminal demand. The supply is currently high, and the demand improvement is limited, but the situation may marginally ease in September [4]. Group 3: Summary of Each Section 1. Daily Market Summary (1) Fundamentals - **Price**: On August 21, the styrene main contract closed up 0.05% at 7289 yuan/ton with a basis of 26 (+36 yuan/ton), and the pure benzene main contract closed down 0.08% at 6200 yuan/ton [2]. - **Cost**: On August 21, Brent crude closed at 62.7 (+0.9 dollars/barrel), WTI at 66.8 (+1.1 dollars/barrel), and the spot price of East China pure benzene was 6110 yuan/ton (+5 yuan/ton) [2]. - **Inventory**: Styrene sample factory inventory was 20.3 tons (-0.3 tons, -1.1% MoM), Jiangsu port inventory was 16.2 tons (+1.3 tons, +8.5% MoM), and pure benzene port inventory was 14.4 tons (-0.2 tons, -1.1% MoM) [2]. - **Supply**: Styrene production may decrease in late August due to plant maintenance. Currently, the weekly output is 37.1 tons (+0.2 tons), and the plant capacity utilization rate is 78.5% (+0.3%) [2]. - **Demand**: The capacity utilization rates of downstream 3S vary. EPS is 61.0% (+2.9%), ABS is 71.1% (+0%), and PS is 57.5% (+1.1%), showing a continuous increase [2]. (2) Views - **Pure benzene**: The supply is relatively stable with some increase, and the demand shows a mixed trend. The cost is supported by the short - term oil price rebound, but the long - term oil price may face pressure. Overall, the short - term fundamentals improve, but problems remain [3]. - **Styrene**: It rebounded with the cost in the short - term. The supply is high, and the demand improvement is limited. In September, the supply may contract due to maintenance, and the demand may enter the peak season, which may ease the supply - demand contradiction [4]. 2.
