节前需求回落，盘?表现承压

1. Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "oscillation" [8] 2. Core View of the Report - As the holiday approaches, the inventory of steel products accumulates rapidly, the fundamentals lack highlights, and the futures market shows weakness. The total inventory pressure of iron ore continues to increase, and the current market has average expectations for post - holiday demand, causing the futures market to face pressure. There are disturbances on the coal supply side, with more coal mines taking holidays before the Spring Festival, but the coal - coke replenishment is coming to an end, and the demand support is limited, resulting in wide - range oscillations at a low level in the futures market. The oversupply of glass and soda ash suppresses the futures prices. Overall, the winter storage of furnace materials is coming to an end, the fundamentals in the off - season are lackluster, and there is short - term downward adjustment pressure in the futures market, but there are still macro disturbances before the Two Sessions, and the downward space of the futures market is limited [3][4] 3. Summary According to Relevant Catalogs 3.1 Iron Element - Iron ore: The inventory pressure of iron ore continues to increase, and there are still expectations of weather disturbances on the supply side. The current market has average expectations for post - holiday demand, causing the futures market to face pressure. However, important meetings will be held after the holiday, and there are still macro expectations. After the rapid decline of the futures market, the pressure has been released. Attention should be paid to market sentiment changes. The supply and daily consumption of scrap steel are expected to decline seasonally, and the steel mill replenishment is basically completed. It is expected that the spot price will oscillate before the holiday [3] 3.2 Carbon Element - Coke: The subsequent growth space of coke supply is limited, while the expectation of downstream steel mill resumption still exists. The coke supply - demand structure will continue to be healthy, but the bullish driving force of the fundamentals is also limited. The spot is expected to remain stable for the time being, and the futures market is expected to follow the coking coal on the cost side [4] - Coking coal: Before the Spring Festival, the supply and demand of coking coal will continue to decline. After the Spring Festival, the resumption of coal mines will still be restricted. The fundamentals of coking coal may continue to be healthy. The spot is expected to oscillate, and the futures market is expected to oscillate widely due to the influence of capital sentiment [4] 3.3 Alloys - Manganese silicon: The manganese silicon market has strong supply and weak demand, and the upstream de - stocking pressure is increasing. 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 manganese silicon contract will oscillate around the cost [4] - Ferrosilicon: The ferrosilicon market has weak supply and demand, and the fundamental contradictions are limited. The market transactions are light around the Spring Festival, and the upward driving force of the futures market is insufficient. It is expected that the ferrosilicon futures price will run at a low level around the cost [4] 3.4 Glass and Soda Ash - Glass: There are still expectations of disturbances in glass supply, but the inventory of the middle and downstream is moderately high. From the perspective of fundamentals, the current supply and demand are still in surplus. If there is no more cold - repair before the end of the year, the high inventory will always suppress the price [4] - Soda ash: The overall supply and demand of soda ash are still in surplus. It is expected to oscillate in the short term. In the long run, the oversupply pattern will further intensify, and the price center will still decline, promoting capacity de - stocking [4] 3.5 Specific Product Analysis - Steel: Before the holiday, the supply and demand are both weak, and the futures market shows weakness. The spot market transactions are weak, the steel mill resumption rhythm is accelerating, but the five major steel products' output is decreasing month - on - month. The demand is seasonally weakening, and the inventory is accumulating rapidly. There is short - term downward adjustment pressure in the futures market, but there are still macro disturbances before the Two Sessions, and the downward space is limited [10] - Iron ore: The hot metal output has slightly rebounded, and the port inventory has decreased. The global shipment volume has slightly declined month - on - month. The supply is expected to be relatively loose, the demand is stable, and the overall inventory pressure is still accumulating. The futures market is under pressure, and attention should be paid to market sentiment changes [10] - Scrap steel: The supply and demand are seasonally decreasing, and the steel mill replenishment is basically completed. The supply and daily consumption are expected to decline seasonally, and it is expected that the spot price will oscillate before the holiday [12] - Coke: The supply has slightly increased, and the replenishment is basically completed. The supply has increased month - on - month, the demand is supported by rigid demand, and the inventory is in a healthy supply - demand structure. The spot is expected to remain stable, and the futures market will follow the coking coal [13][14] - Coking coal: The middle and upstream are de - stocking before the festival, and the price is oscillating with low volatility. The supply is expected to decline before the holiday, the import is at a high level, the demand is decreasing, and the price is oscillating with low volatility. The spot is expected to oscillate, and the futures market is expected to oscillate widely [15][16] - Glass: The contradictions before the holiday are limited, and the inventory has increased month - on - month. The supply has disturbance expectations, the demand is weak, the inventory is high, and it is expected to oscillate in the short term [17] - Soda ash: The supply remains at a high level, and the inventory has increased month - on - month. The supply has rebounded month - on - month, the demand is weakening, the supply and demand are in surplus, and it is expected to oscillate in the short term and decline in the long term [17][19] - Manganese silicon: The cost is firm, and the post - holiday inventory is expected to increase. The upstream inventory is high, the cost is increasing, the demand is weakening, and the supply is strong. It is expected that the futures price will oscillate around the cost [19][20] - Ferrosilicon: The supply - demand contradictions are not significant, and the cost support still exists. The cost support is strengthening, the demand is weakening, the supply is at a low level, and it is expected that the futures price will run at a low level around the cost [21]
