Report Title - Manganese Silicon Weekly Report (August 18 - August 22) [1] Report Industry Investment Rating - Not provided Core Viewpoints - In the cost aspect, the centralized pre - procurement of northern alloy plants is nearing completion, port activity has decreased, high - price offers from miners are reducing, and the "buy on rising" sentiment in the market has increased with strong wait - and - see mood and cautious procurement. Coke has been stable recently, and the current spot cost has little change [2]. - Regarding the supply side, the overall start - up of the north and south markets has little fluctuation.

Due to the weak operation of the silicon - manganese futures market and cost inversion, alloy plants are reluctant to lower prices, and many are not quoting prices, with a rising bearish sentiment in the market [2]. - From the demand side, affected by the decline of the silicon - manganese futures market, the new steel tender prices have dropped significantly after the HeSteel tender, with acceptance pricing concentrated around 5850 - 5900 yuan/ton, and the acceptance of silicon - manganese alloy is average. The approaching military parade production restrictions in northern steel mills are expected to temporarily suppress the demand for silicon - manganese alloy [2]. - Overall, the sentiment in the silicon - manganese market has cooled slightly recently. The silicon - manganese price stabilized after a mid - week decline, and the future price trend still depends on the futures market fluctuations and changes in supply - demand fundamentals.
