1. Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "oscillating" [6][7][8] 2. Core Viewpoints of the Report - On October 20, 2025, the main economic indicators for September were announced. Data in real estate, infrastructure, and other fields related to black building materials remained poor. The prices of leading sector varieties dropped from their intraday highs and remained under pressure at night. The demand side of the industry continued to be weak. With the "15th Five - Year Plan" meeting underway, the market still expects policy benefits to boost confidence [1][2] - Entering late October, the traditional peak season is ending, and with tariff disturbances, the demand side is unlikely to perform well. Although high molten iron still supports the furnace charge in the short term, the market's negative feedback expectation strengthens as the peak season ends. Attention should be paid to the possibility of the "15th Five - Year Plan" meeting releasing sector benefits [3] 3. Summary by Related Catalogs 3.1 Iron Element - Iron Ore: Overseas mine shipments rebounded slightly, and the arrival volume at 45 ports dropped from a high level. The demand side saw a slight decline in the average daily output of sample molten iron and the steel mill profitability rate, but molten iron remained at a high level. Port inventories continued to accumulate. The fundamentals of iron ore weakened marginally, but the overall pressure was not prominent. Policy expectations may cause fluctuations, and steel demand improved slightly. The future of Sino - US trade relations is uncertain, so short - term prices are expected to oscillate [2][8] - Scrap Steel: The arrival volume at steel mills decreased, and the electric furnace profit improved slightly. The fundamentals of scrap steel have no obvious contradictions. With the current pressure on finished product prices and poor electric furnace profits, short - term prices are expected to follow finished products [2][10] 3.2 Carbon Element - Coke: The short - term supply and demand of coke remained tight. With rising costs, the second price increase was initiated, but steel prices were still weak. The price increase needs time to be implemented, and coke prices are expected to oscillate [2][11][13] - Coking Coal: Supply disturbances continued, and the production increment space of coal mines was limited. With low inventories, the fundamentals were healthy. Coking coal prices are expected to oscillate [2][11][12] 3.3 Alloys - Manganese Silicon: Short - term high costs, peak demand season, and policy expectations support the price, but the market's supply - demand expectation is pessimistic, and there is still room for the price center to decline in the future [3][15] - Silicon Iron: Short - term peak demand season, policy expectations, and firm costs support the price, but the supply - demand relationship is becoming looser, and there is still downward pressure on prices [3][16] 3.4 Glass and Soda Ash - Glass: Spot sales and production are weak. After the negative feedback between futures and spot, short - term prices show an oscillating and weakening trend. In the long term, market - oriented capacity reduction is needed, and prices are expected to oscillate downward [3][12] - Soda Ash: The supply surplus pattern remains unchanged. It is expected to follow macro - changes and oscillate widely. In the long run, the price center will decline to promote capacity reduction [3][14] 3.5 Steel - The fundamentals of steel still have contradictions. After the National Day, the demand for five major steel products recovered to a limited extent, and the inventory level is still moderately high. With the domestic important meeting this week, attention should be paid to policy disturbances, and short - term prices are expected to oscillate at a low level [7] 3.6 Commodity Index - On October 20, 2025, the comprehensive index of CITIC Futures commodities showed that the commodity 20 index was 2533.64, down 0.15%; the industrial products index was 2183.97, up 0.37%. The steel industry chain index was 1976.21, up 0.55% on the day, up 0.13% in the past 5 days, down 1.65% in the past month, and down 6.26% since the beginning of the year [102][104]
