[SMM Magnesium Weekly Review: Tight Supply and Recovering Demand Drove Magnesium Prices Steadily Higher This Week, Breaking 17,500] This week, China's magnesium industry chain as a whole held up well. On the raw material side, the dolomite market remained stable. Part of the suspended output in core production areas was supplemented by supply from surrounding regions, while stable operating rates at downstream primary magnesium smelting plants supported demand and the supply-demand balance. Affected by rising crude oil prices, subsequent delivered prices may rise slightly. The magnesium ingot market stayed firm, and both production and sales in major producing areas were strong. Geopolitical disruptions pushed up energy expectations, prompting producers to hold back sales and tightening supply. Rigid downstream demand, export order lock-ins, and a boost from industry conferences jointly drove magnesium prices higher. Offshore quotations were adjusted in line with ex-factory prices, and although bidding-based shipment prices were low at the beginning of the week, they rebounded later, while new orders declined. Magnesium powder remained firm, supported by higher magnesium ingot prices, while increased operating rates at magnesium plants ensured supply and both domestic and overseas demand recovered. The magnesium alloy market also stayed strong, with stable operating rates at top-tier enterprises, new capacity coming on stream, and downstream end-use demand being released, supported by ample orders and a supply-demand balance.

The company will strive based on the upper end of market growth, hoping to achieve more than 60 Gwh.

[SMM Silicon-Based PV Morning Briefing] Silicon metal: The silicon metal market remained in a weak stalemate. Yesterday, SMM east China oxygen-blown #553 silicon was at 9,100-9,200 yuan/mt, down 50 yuan/mt from the previous day. Weaker expectations for production cuts on the supply side weighed on market sentiment. At the start of the week, futures prices trended weaker, and the center of spot transactions for some cargoes in the market edged lower. Cost support from the raw material side remained firm, and prices may fall back into stalemate. Polysilicon: N-type recharging polysilicon was quoted at 35.5-41.5 yuan/kg. Polysilicon prices have continued to decline recently, mainly affected by market sentiment and inventory exit the market among some leading enterprises. At present, low-priced polysilicon has already fallen below the cost line of some producers, and the sentiment to hold quotes firm has strengthened somewhat. Relevant meetings still need to be monitored going forward.
