1. Report Industry Investment Rating - No information provided 2. Core View of the Report - The current iron ore supply is relatively abundant, with the iron - water production on the demand side continuously declining and the rigid - demand procurement weakening. However, there is still an expectation of steel mill restocking. In the short term, the market will maintain a volatile operation. Attention should be paid to the restocking demand of steel mills for winter storage and changes in macro - sentiment. The trading strategy is range - bound [4][5]. 3.

Demand - In the week of December 19th, the daily average iron - water production was 226,550 tons, a week - on - week decrease of 26,500 tons. Due to more annual and environmental maintenance of steel mills and stricter environmental restrictions in Hebei, the iron - water production continued to decline, and the rigid - demand support was weak [4]. - The profit of steel mill blast furnaces increased slightly [66]. Inventory - The inventory of imported ore continued to increase, the number of ships at the port increased by 4 to 111, the port congestion increased, and the port inventory continued to accumulate and remained at a high level. The steel mill inventory continued to decline at a low level, and the winter - storage restocking demand had not started yet, with expected games still existing [4]. - The port dredging volume declined from a high level, the inventory of Australian ore increased slightly, the inventory of Brazilian ore declined from a high level, the coarse powder inventory fluctuated at a high level, and the lump ore inventory increased slightly.
