市场供需较稳，煤焦延续反弹态势

1. Report Industry Investment Rating - Most of the black building materials are expected to oscillate, including steel, iron ore, scrap steel, coke, coking coal, glass, soda ash, ferrosilicon, and ferromanganese [2][6][8][9][10][11][12][13][14][15][16] 2. Core Viewpoints - The black series as a whole has rebounded, driven by the rebound of coking coal and coke. However, due to the approaching off - season in the domestic construction and manufacturing industries, demand is hard to increase. With the large increase in iron ore shipments and the lack of obvious improvement in the supply of coking coal and coke, the market is expected to oscillate in the future [1][2][6] 3. Summary by Relevant Catalogs Iron Element - Overseas mines are expected to increase shipments seasonally before early July, but the year - on - year increase is limited. Steel mills' profitability and hot metal production have slightly decreased, but are expected to remain high in the short term. Last week, the arrival decreased, leading to a slight decline in inventory. With the seasonal increase in overseas shipments, there is an expectation of a small - scale phased increase in ore inventory, but the amplitude is expected to be limited. The overall supply - demand contradiction is not prominent, and the iron ore price is expected to oscillate [2][8] Carbon Element - The number of coal mines shut down due to inventory pressure and environmental inspections has increased, and coking coal production has declined, but the overall market supply is not tight. Coke production has declined from a high level, and there is an expectation of further decline. During the price cut cycle, coke enterprises' enthusiasm for raw material replenishment is poor, and the upstream inventory of coking coal remains at a high level in recent years. The supply contraction is limited, and the downstream demand in the off - season tends to decline. The coking coal price lacks a driving force for a trending increase in the short term [3] Alloys - Silicon Manganese: There was a rumor about a mine dam failure, but it was verified that production and transportation are normal. Manganese ore prices have stabilized, and traders are reluctant to sell at low prices. A factory in Inner Mongolia plans to put new production capacity into operation in the second half of the month, and silicon manganese production may continue to increase. With the off - season approaching, the supply - demand of silicon manganese tends to be loose, and the manganese ore price is expected to loosen. The futures price is expected to oscillate in the short term [3][15] - Silicon Iron: Affected by the improvement in the energy sector, the silicon iron futures price rose from a low level. The supply is expected to increase slightly, and the downstream is about to enter the off - season, with a strong willingness to destock. The market sentiment is still cautious. The futures price is expected to oscillate in the short term, and attention should be paid to steel procurement and production [16] Glass and Soda Ash - Glass: In the off - season, demand is declining, deep - processing demand is weakening, and the spot price is falling. There is a production line planned for cold repair, and 5 production lines are waiting to produce glass. The supply pressure remains. The market is expected to be weakly oscillating in the short term [6][13] - Soda Ash: The supply surplus pattern remains unchanged. After the resumption of maintenance, the short - term is expected to oscillate, and the price center will decline in the long term [6][13] Individual Commodity Analysis - Steel: The domestic policy is in a vacuum period, and the war between Iran and Israel has repaired the valuation of overseas commodities. The overall supply and demand of steel have weakened this week, but inventory is still being depleted. The steel price is expected to oscillate in the short term [8] - Scrap Steel: With the deepening of the off - season for building materials, the apparent demand for rebar has decreased. The supply of scrap steel is tight, but the market is pessimistic about off - season demand. The scrap steel price is expected to oscillate [9] - Coke: Terminal steel demand is in the off - season, and downstream procurement is cautious. The supply has decreased, but the upstream inventory is high, and the demand is expected to decline. The coke price is under downward pressure [10][11] - Coking Coal: The spot market is pessimistic, and the supply remains loose. The production decline is limited, and the downstream demand in the off - season is expected to fall. The coking coal price increase is restricted in the short term [12]
