Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - During the policy "vacuum period" and with stable industrial operations, the prices of black building materials oscillated. The iron ore, which had a relatively large decline earlier, rebounded significantly. At night, the sector continued to oscillate, and the coking coal and coke futures prices weakened due to the fourth round of coke price increase negotiations [2][3]. - Currently, the contradictions in the industrial chain are not prominent, and there are no new changes in the macro and policy aspects to affect market expectations. Therefore, the black building materials prices lack a clear trend and are expected to remain volatile in the short term. If there are more favorable policies in the future, there may be a phased upward opportunity [3][7]. Summary by Relevant Catalogs Iron Element - **Iron Ore**: Port trading volume was 98.8 (-9) million tons. The spot price was strong. Overseas mine shipments were relatively stable but decreased month - on - month. The arrival of goods decreased week - on - week. The daily average molten iron was stable in the short term, but there was an increasing expectation of seasonal decline. The port inventory continued to accumulate, but the marginal supply - demand might improve. It is expected that after a rapid price decline, it will oscillate strongly in the short term [9]. - **Scrap Steel**: The average price of crushed scrap in East China decreased by 4 yuan/ton. The supply of scrap steel decreased, and the demand was weak. The overall supply - demand of scrap steel was weak, and it is expected that the spot price will oscillate with the finished products in the short term [10]. Carbon Element - **Coke**: The futures market oscillated at a low level. The spot price in Rizhao Port increased by 10 yuan/ton. The supply was difficult to increase, and the demand was stable in the short term. After three rounds of price increases, the steel mills were resistant to further increases, but the fourth - round price increase was likely to be implemented. The coke price is expected to oscillate with the coking coal [10][12]. - **Coking Coal**: The supply was still tight, and the Mongolian coal import increase was limited. The spot price was strongly supported, but the futures price was suppressed by the finished products. It is expected that the coking coal price will oscillate [13]. Alloys - **Manganese Silicon**: The short - term cost supported the price, but the supply - demand was loose, and there was insufficient driving force for price increase. It is expected to operate at a low level around the cost [3]. - **Silicon Iron**: The short - term cost was strong, but the supply - demand was loose, and the upward driving force was insufficient. It is expected to operate at a low level around the cost [3]. Glass and Soda Ash - **Glass**: The national average price decreased by 3 yuan/ton. The supply might be disrupted, and the mid - and downstream inventories were moderately high. The current supply - demand was in surplus. If there was no more cold repair by the end of the year, the price would be under pressure; otherwise, it would rise [4][14]. - **Soda Ash**: The cost increased, and the bottom support was obvious. However, the supply - demand surplus suppressed the price increase. Recently, the weakening of the glass price dragged down the soda ash price. It is expected to oscillate in the short term and decline in the long term [4][15]. Steel - The spot market transactions were weak. The steel mills' profitability decreased, and the production decreased. The demand declined, and the overall inventory continued to decrease, but it was still higher than the same period last year. The fundamentals had contradictions. It is expected that during the off - season, the demand will weaken, and the price will have limited downward space. Pay attention to the potential upward driving force from the macro and policy [9]. Commodity Index - On November 12, 2025, the comprehensive index, the commodity 20 index, the industrial products index, and the PPI commodity index all increased. The steel industry chain index increased by 0.63% on that day, decreased by 1.21% in the past 5 days, increased by 1.24% in the past month, and decreased by 5.87% since the beginning of the year [98][99].
