钢铁供给快速恢复，加剧炉料与成品材分化

1. Report Industry Investment Rating - The report gives a "Neutral" rating to the black building materials industry, with a mid - term outlook of "Oscillation" [7]. 2. Core Viewpoints of the Report - As the traditional peak season deepens, the failure of the building materials peak season has intensified the differentiation between furnace materials and finished products. Furnace materials are stronger than building materials due to strong real - demand and restocking expectations, and provide cost support for building materials. The intra - sector differentiation and overall price support are expected to remain [7]. - The steel inventory is at a moderately high level, and the fundamental contradictions are still accumulating. The fundamentals of rebar are weaker than those of hot - rolled coils. The market is still cautious about the peak - season demand. However, with the restoration of hot metal and pre - National Day restocking demand, it may support the futures prices, but rebar is expected to perform weaker than hot - rolled coils [8]. 3. Summary by Relevant Catalogs 3.1 Iron and Steel - Core Logic: The spot market trading volume of steel is weak, with rigid - demand purchases at low prices. The trading volume of building steel is weaker than that of hot - rolled coils. Due to shrinking profits, some steel mills have shut down for maintenance. The production of rebar has decreased, and demand has declined, with inventory pressure in Hangzhou. The supply and demand of hot - rolled coils have returned to pre - parade levels, with improved downstream purchasing sentiment and inventory destocking. The supply of the five major steel products has decreased while demand has increased, and inventory is still accumulating but at a slower pace [8]. - Outlook: The steel inventory is moderately high, and fundamental contradictions are accumulating. The fundamentals of rebar are weaker than those of hot - rolled coils. The market is cautious about peak - season demand. However, with the restoration of hot metal and pre - National Day restocking demand, it may support the futures prices. It is recommended to pay attention to the strategy of going long on hot - rolled coils and short on rebar [8]. 3.2 Iron Ore - Core Logic: Port trading volume has increased. Overseas mine shipments and arrivals at 45 ports have decreased, mainly due to port maintenance in Brazil, which is expected to have little impact on annual shipments. The hot - metal production has recovered to over 2.4 million tons per day, supporting short - term demand. The port inventory has increased, the berthing inventory has decreased, and the in - plant inventory has slightly replenished, with the total inventory slightly decreasing and the overall inventory at a moderate level [9]. - Outlook: The demand for iron ore has recovered to a high level, and the in - plant inventory is low. There is an expectation of pre - festival restocking in the middle and late period. The fundamentals are healthy, but the peak - season demand of the finished - product end needs further verification, limiting the upside space of iron ore. It is expected that the price will oscillate in the short term [9]. 3.3 Scrap Steel - Core Logic: The supply of scrap steel has slightly decreased, and the demand has increased slightly. The total daily consumption of scrap steel in both long - and short - process production has increased slightly, and the factory inventory has slightly decreased, with the available inventory days at a low level [11]. - Outlook: The fundamental contradictions of scrap steel are not prominent. The pressure on finished - product prices has led to low EAF profits, but resources are still tight. It is expected that the price will oscillate in the short term [11]. 3.4 Coke - Core Logic: The supply and demand of coke have both increased, with daily production reaching a three - month high and total inventory slightly increasing. Although the supply is becoming more relaxed, the current supply - demand contradiction is acceptable. Steel mills still have restocking needs during peak - season production. After the futures market has priced in two rounds of price cuts, the price is expected to oscillate in the short term [3]. - Outlook: The supply of coke has recovered more than expected, but the hot - metal production has also recovered rapidly. Steel mills still have restocking needs during peak - season production. After two rounds of price cuts have been priced in the futures market, the price is expected to remain oscillating in the short term. Attention should be paid to the restocking situation of downstream steel mills and the hot - metal production during the peak season [12]. 3.5 Coking Coal - Core Logic: The supply of coking coal has basically recovered, with domestic coal mines resuming production and high - level imports from Mongolia. The demand for coking coal is high due to the high - level production of coke. However, after the previous restocking, the current procurement is mostly on - demand, and the spot market is under pressure. Attention should be paid to the extent of coal - mine复产 [12]. - Outlook: After the parade, coal mines have quickly resumed production and are expected to maintain a stable production rhythm. With the arrival of the downstream demand peak season and high - level coke production, the on - demand restocking will still support the coking coal price [13]. 3.6 Glass - Core Logic: The sentiment in the domestic commodity market has weakened, and the fundamental logic has returned as the delivery approaches. The demand is in the off - season, and the downstream lacks restocking ability. Although some upstream manufacturers have promoted sales by raising prices, the supply uncertainty has increased due to potential production - line ignitions and possible shutdowns in the Shahe area. The fundamentals are still weak, and the spot price decline may be limited, with a moderately high futures valuation [13]. - Outlook: The actual demand is weak, but there are expectations of the peak season and policies. After the mid - stream destocking, there may be another round of oscillations. In the long - term, market - oriented capacity reduction is still needed, and if the price returns to fundamental trading, it is expected to oscillate downward [13]. 3.7 Soda Ash - Core Logic: The upstream inventory of soda ash has decreased, but the supply is still at a high level. The long - term supply pressure remains due to un - cleared production capacity. The demand for heavy soda ash is stable with a slight increase, while the downstream of light soda ash has weak restocking sentiment. After the resolution of shipping issues, the mid - stream inventory has accumulated, and the downstream's willingness to accept goods is weak [16]. - Outlook: The oversupply situation of soda ash has not changed. After the futures price decline, the spot - futures trading volume has increased slightly. It is expected to oscillate widely in the future. In the long - term, the price center will decline to promote capacity reduction [16][20]. 3.8 Alloys (Manganese Silicon and Ferrosilicon) - Manganese Silicon - Core Logic: A new round of steel procurement has started, and the first - round inquiry price in September has decreased by 400 yuan/ton compared to the previous month. The fundamentals lack upward drivers, and although the cost and peak - season expectations support the futures price in the short term, the market supply - demand outlook is pessimistic in the long - term [4]. - Outlook: The short - term cost and peak - season expectations support the futures price, but there is significant downward pressure on the price in the long - term. Attention should be paid to the decline in raw - material costs [17]. - Ferrosilicon - Core Logic: The first - round inquiry price in September has decreased by 330 yuan/ton compared to the previous month. The supply has increased, and the demand from the metal - magnesium market is weak. The market supply - demand relationship has hidden concerns [4][18]. - Outlook: The stable cost of semi - coke and electricity provides short - term support for the ferrosilicon price. With peak - season expectations, the downward space of the futures price may be limited, but the price center is expected to decline in the long - term. Attention should be paid to the adjustment of electricity costs in the main production areas [18].
