Report Industry Investment Rating - The report gives a medium - term outlook of "sideways" for the black building materials industry [6] Core View of the Report - The market is in a game between reality and expectation, with prices mainly moving sideways. The downstream procurement enthusiasm for coking coal and coke has increased, and the spot price of coke has started to rise. However, coal mines are resuming production in January, and Mongolian coal imports have rebounded to a high level, so there is still high supply pressure, and the futures prices are expected to move sideways. The resumption of hot metal production and pre - holiday restocking expectations support the iron ore price, but high inventory limits the upside space. In the off - season, demand is seasonally weak. As steel mills gradually resume production, the pressure of inventory accumulation in the steel sector is becoming more obvious, and fundamental contradictions are gradually accumulating, suppressing the valuation of the steel futures market. The oversupply of glass and soda ash continues to suppress the futures prices [2]. Summary by Relevant Catalogs 1. Iron Element - Iron ore: Port inventory is continuously accumulating, and there are expectations of disturbances on the supply side. The resumption of hot metal production and pre - holiday restocking support the ore price. The supply and demand on both sides in reality still need to be verified, and it is expected to move sideways in the short term. The supply and demand of scrap steel are both weak. Steel mills have relatively high inventory, and restocking has slowed down. However, the profit of electric furnaces is acceptable, and the daily consumption is at a high level, which supports the demand. The overall fundamental contradictions are not prominent, and the spot price is expected to move sideways [2]. 2. Carbon Element - Coke: The cost side of coke has shown signs of stabilization, and the expectation of steel mill复产 still exists. As the mid - and downstream winter restocking gradually begins, and the sharp rise in the futures market may drive the entry of spot - futures and speculative demand for procurement, the supply - demand structure of coke may gradually tighten. The spot price increase is expected to be implemented, and the futures price is expected to follow the coking coal [3]. - Coking coal: As the Chinese New Year approaches, the intensity of winter restocking gradually increases, and the impulse behavior of Mongolian coal imports has improved. The overall supply pressure will be relieved, the fundamentals of coking coal will continue to improve marginally, and there is still upward momentum in the futures and spot prices [3]. 3. Alloys - Manganese silicon: The pattern of loose supply and demand of manganese silicon continues, the pressure of upstream inventory reduction is relatively large, and it is difficult to transmit costs downward. When the futures price rises to a high level, it will face selling hedging pressure. In the medium term, the futures price is still expected to gradually fall back to the cost valuation level [3]. - Ferrosilicon: Currently, the supply and demand in the ferrosilicon market are both weak, and the fundamental contradictions are relatively limited. In the short term, the futures price is expected to follow the sector [3]. 4. Glass and Soda Ash - Glass: There are still expectations of disturbances in supply, but the inventory of mid - and downstream is moderately high. Fundamentally, the current supply and demand are still in excess. If there is no more cold repair by the end of the year, the high inventory will always suppress the price, and it is expected to move sideways weakly. Otherwise, the price will rise [3]. - Soda ash: The overall supply and demand of soda ash are still in excess. It is expected to move sideways in the short term. In the long run, the pattern of oversupply will further intensify, and the price center will continue to decline, promoting capacity removal [3]. 5. Specific Varieties Analysis - Steel: The spot market trading is average. With the end of some steel mill overhauls, iron and steel production continues to increase. In the off - season, demand is seasonally weak, and the overall steel inventory has stopped falling and started to rise. The fundamental contradictions are gradually accumulating. But with the resumption of steel mills and winter restocking, the cost side still has support, and the futures price will move in a wide sideways range [8]. - Iron ore: The spot price is moving sideways. Overseas mine shipments have decreased month - on - month, and the arrivals have increased. The fundamentals on both the supply and demand sides still need to be verified, and it is expected to move sideways in the short term [8]. - Scrap steel: The supply and demand of scrap steel are both weak. Steel mills have high inventory, and restocking has slowed down. However, the profit of electric furnaces is acceptable, and the daily consumption is at a high level, which supports the demand. The overall fundamental contradictions are not prominent, and the spot price is expected to move sideways [9]. - Coke: The cost side of coke has strong support, and the spot price has started to rise. The demand for coke is well - supported by the resumption of steel mills, and the inventory of steel mills is steadily increasing. The supply - demand structure is expected to tighten, and the futures price is expected to follow the coking coal [12]. - Coking coal: The supply pressure will be relieved, the fundamentals will continue to improve marginally, and there is still upward momentum in the futures and spot prices [12]. - Glass: The supply has expectations of disturbances, but the mid - and downstream inventory is moderately high. The current supply and demand are in excess. 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 move sideways weakly [13]. - Soda ash: The overall supply and demand are in excess. It is expected to move sideways in the short term. In the long run, the pattern of oversupply will intensify, and the price center will decline [16]. - Manganese silicon: The supply - demand pattern is loose, the upstream inventory reduction pressure is large, and it is difficult to transmit costs downward. The futures price is expected to gradually fall back to the cost valuation level in the medium term [16]. - Ferrosilicon: The supply and demand are both weak, and the fundamental contradictions are limited. In the short term, the futures price is expected to follow the sector [17].
