商品情绪转弱，盘?波动加剧

1. Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "Oscillation" [5] 2. Core View of the Report - In the off - season, the pressure of inventory accumulation in the steel sector is gradually emerging, the fundamentals lack highlights, and the futures market follows the market sentiment and weakens. The resumption of production in steel mills is slow, and the iron ore market is under pressure from high shipments and high inventory, while pre - holiday restocking in the demand side supports the ore price. The first round of price increase for coke has been implemented, Mongolian coal imports remain at a high level, but there is an expectation of supply tightening for coking coal before the Spring Festival, and the futures market fluctuates sharply. There are disturbances in the glass supply, but the oversupply situation continues to limit the upside space of the glass futures market. Overall, the off - season fundamentals are lackluster, there is pressure above the futures price, but the restocking intensity before the Spring Festival still exists, and the subsequent resumption of production by steel enterprises is expected to further boost the restocking expectation, and the cost side still has support. It is expected that the sector will oscillate widely at the bottom, and attention should be paid to macro - policy disturbances [1][2][5] 3. Summary of Each Category 3.1 Iron Element - Iron Ore: Overseas mine shipments increased month - on - month, and arrivals continued to weaken. Due to the impact of weather, there is an expectation of supply disturbances. On the demand side, iron - making water production decreased slightly month - on - month, steel mills' profitability weakened, rigid demand was stable, and steel mills' restocking accelerated before the Spring Festival, but the support for prices may gradually weaken as restocking progresses. Port inventory continued to accumulate, and the overall inventory pressure is increasing. It is expected to oscillate in the short term, and attention should be paid to market sentiment changes [6][7] - Scrap Steel: Both supply and daily consumption are expected to decline seasonally. As restocking nears the end, the overall fundamentals will weaken marginally, and it is expected that the spot price will mainly follow the finished products [8] 3.2 Carbon Element - Coke: The first round of price increase has been fully implemented, and coking profits have improved significantly. The overall supply change is limited. On the demand side, steel - mill blast furnaces are in a state of both resumption and maintenance, and iron - making water production remains high, with strong rigid demand support. The inventory in steel mills has increased steadily. The supply growth space is limited, and the downstream steel - mill resumption expectation still exists. The supply - demand structure will remain healthy, but the fundamental bullish driving force is also limited. The spot is expected to remain stable for the time being, and the futures market is expected to follow the cost side (coking coal) [10][11] - Coking Coal: The domestic supply is temporarily stable, and Mongolian coal imports remain at a high level. The downstream winter - storage restocking is still in progress, and the upstream coal - mine inventory is being continuously digested. As the winter - storage inventory gradually reaches the target, the spot - market sentiment has cooled down, and the online auctions show mixed results, with the overall coal price weakly stable. The futures market oscillates due to the impact of capital - sentiment fluctuations. Before the Spring Festival, domestic coal - mine production will gradually decline, the fundamentals will remain healthy, but the fundamental bullish driving force is limited. The spot is expected to oscillate before the Spring Festival, and the fluctuation of the futures - market sentiment remains to be observed [12] 3.3 Alloys - Manganese Silicon: The market continues to be in a state of loose supply and demand, and the upstream has great pressure to destock. When the futures market rises to a high level, it will face selling - hedging pressure. It is expected that the futures price of the main contract will mainly oscillate around the cost valuation. Attention should be paid to the adjustment range of raw - material prices and the change in manufacturers' production - control intensity [15] - Silicon Ferrosilicon: The supply - and - demand situation is weak, and the fundamental driving force is limited. The low trading activity before the Spring Festival suppresses the upside space of the futures market. It is expected that the futures price will mainly oscillate around the cost valuation. Attention should be paid to the adjustment range of semi - coke prices and settlement electricity prices, as well as the production - control trends in the main production areas [16] 3.4 Glass and Soda Ash - Glass: The supply has an expectation of disturbances, but the inventory of the middle and lower reaches is moderately high. Currently, the supply - and - demand situation is still in oversupply. If there is no more cold - repair by the end of the year, the high inventory will suppress the price, and it is expected to oscillate weakly; otherwise, the price will rise [13] - Soda Ash: The daily production is continuously at a high level, and restocking is nearing the end. The overall supply - and - demand situation is still in oversupply. It is expected to oscillate in the short term. In the long run, the oversupply situation will further intensify, and the price center will continue to decline to promote capacity reduction [13]
