Report Industry Investment Rating - Not provided in the content Core Views of the Report - This week, manganese - silicon futures prices rose due to South African manganese ore policies and union negotiation events but fell as Gemco Mine shipped its first batch of manganese ore since early 2024. Silicon - iron prices were volatile and weak due to the downward shift of raw material cost centers [3][42]. - The supply of silicon - iron decreased month - on - month, with significant production cuts in Ningxia, Shaanxi, and Gansu. The supply of manganese - silicon rebounded slightly month - on - month, and production in major producing areas was relatively stable [3][42]. - Silicon - iron inventory increased month - on - month, with obvious inventory accumulation in Inner Mongolia. Manganese - silicon inventory decreased month - on - ten - days, but Ningxia was still in the inventory accumulation state. The warehouse receipt inventory of both silicons declined from the high level [3][42]. - Blast furnace operation and hot metal production decreased month - on - month and may have peaked and declined. The seasonal performance of the demand side was better than last year [3][42]. - The cost center of silicon - iron continued to move down, while the cost center of manganese - silicon increased slightly, supporting the futures price of manganese - silicon. The cost side may loosen again after the arrival of low - cost manganese ore and Australian ore in June [3][42]. - Overall, the supply - demand pattern of both silicons has tightened marginally recently, and a tight balance may occur at the end of the second quarter. Attention should be paid to the price changes of raw materials, the production rhythm of steel mills, the subsequent shipment and arrival of global manganese ore, and the implementation of ore - end policies and strike events [4][42].
