1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - The steel and ore market will maintain a short - term oscillating trend. The iron ore's performance is still stronger than that of finished steel products. The rebar has reached a new low this week, while the iron ore has reached a new high. The rebar's pressure level is 3230 and support level is 3050. The hot - rolled coil's pressure level is 3450 and support level is 3250. The pressure level of the main iron ore contract 2601 is 833 and support level is 750. The trading strategy is short - term operation with stop - loss set [5][6]. 3. Summary by Related Catalogs Supply Side - In August 2025, China's daily crude steel output decreased both year - on - year and month - on - month. Considering most steel mills are on the verge of profit and loss, the supply expansion in September is limited. There is an obvious structural differentiation on the supply side. In August, pig iron output increased year - on - year while crude steel output decreased. Currently, blast furnace production contributes more, while electric furnace production is in full - scale loss and its contribution declines [17]. - This week, although blast furnaces resumed, steel supply decreased with structural differentiation. Rebar production and inventory both decreased, while hot - rolled coil production and inventory both increased, with hot - rolled coil performing better than rebar. Shanxi's blast furnaces are gradually resuming production, but the expectation of production restrictions in Tangshan is increasing [15][18]. - This week, the molten iron output increased by 0.47 million tons to 241.02 million tons. The steel mill profitability rate is 58.87%, down 1.5% month - on - month. Electric furnace steel is still in full - scale loss, limiting production enthusiasm [22]. - The total inventory of imported iron ore at 47 ports in China is 143.8168 million tons, a decrease of 744,400 tons month - on - month; the daily average port clearance volume is 3.5103 million tons, an increase of 664,000 tons. The number of ships at ports is 102, an increase of 1.

From September 8th to 14th, Mysteel's global iron ore shipment volume was 35.731 million tons, an increase of 8.169 million tons month - on - month. The total shipment volume from Australia and Brazil was 29.778 million tons, an increase of 6.482 million tons month - on - month [26]. Demand Side - In August, the investment growth rates of real estate, infrastructure, and manufacturing all slowed down, and the domestic demand reduction was obvious. During the transition from the off - season to the peak season in September, the demand has increased but is unstable [17]. Important News - In August 2025, China's crude steel output was 77.37 million tons, a year - on - year decrease of 0.7%; pig iron output was 69.79 million tons, a year - on - year increase of 1.0%; steel output was 122.77 million tons, a year - on - year increase of 9.7%. From January to August, China's crude steel output was 671.81 million tons, a year - on - year decrease of 2.8%; pig iron output was 579.07 million tons, a year - on - year decrease of 1.1%; steel output was 982.17 million tons, a year - on - year increase of 5.5% [13]. - In August, the raw coal output of industrial enterprises above designated size was 390 million tons, a year - on - year decrease of 3.2%, and the decline rate narrowed by 0.6 percentage points compared with July; the daily average output was 12.6 million tons. From January to August, the raw coal output of industrial enterprises above designated size was 3.17 billion tons, a year - on - year increase of 2.8% [13]. - From January to August 2025, the national fixed - asset investment (excluding rural households) was 3.26111 trillion yuan, a year - on - year increase of 0.5%. Among them, private fixed - asset investment decreased by 2.3% year - on - year. In terms of month - on - month, fixed - asset investment (excluding rural households) in August decreased by 0.20% [13]. - On the 16th, there was news that coking and steel enterprises in Tangshan began environmental protection production restrictions. Steel mill blast furnaces were shut down by 40% in terms of equipment, and coking enterprises extended the coking time by 30%. Currently, some enterprises have received production restriction notices, and individual coking enterprises have extended the coking time by 30%. The current overall operating rate of coking plants in the Tangshan market is about 75%. Steel mills have received production restriction notices, and the specific implementation plan is still to be discussed [13]. - Nine listed steel enterprises are accelerating overseas layout, integrating deeply into the global steel industry supply chain through establishing overseas production bases, obtaining international authoritative certifications, and setting up overseas subsidiaries [14]. - British mining company Cadence Minerals recently announced a $4.6 million prepayment financing agreement for the Amapa Iron Ore Project in Brazil. The funds will be used to restart the Azteca beneficiation plant and process high - grade tailings into iron ore concentrates, laying the foundation for the project's long - term expansion plan of an annual output of 5.5 million tons of direct - reduction (DR - grade) iron ore concentrates [14].
