The market was weak in October, and the price center fell slightly
According to the SunSirs commodity market analysis system, the overall domestic silicon spot market showed a weak downward trend in October, with a slight drop in the market center. On October 27, the market price of Tongyang 553# silicon in East China was around 9,300 to 9,400 RMB/ton, and the market price of 441# silicon in Kunming was around 9,700 to 9,900 RMB/ton. The market price of 441# silicon in Huangpu Port was 9,500 to 9,700 RMB/ton, the market price of 441# silicon in Tianjin Port was 9,400 to 9,600 RMB/ton, and the market price of Tongyang 553# in Xinjiang was around 8,600 to 8,800 RMB/ton.
Market Factor Analysis
Supply side
As of October 27, silicon supply was experiencing significant differentiation. With the approaching dry season in the southwest region, silicon producers in Yunnan and Sichuan were reducing production, with some companies anticipating further reductions by the end of this month. Overall operating rates in the southwest region were expected to continue to decline. However, overall operating rates in the northwest region had increased, with the resumption of work at major factories in Xinjiang driving an overall increase in regional operations. While supply complements that of the southwest, overall market supply pressure remained.
Demand side
Overall demand for silicon downstream was weakening. First, overall operating rates in the downstream organosilicon market had declined, providing limited support for raw material silicon procurement. Second, while overall polysilicon production had increased slightly, market sentiment remained cautious, with cautious raw material purchases. Finally, only the downstream aluminum alloy market remained stable, and this, coupled with small exports, provided slight support for raw material silicon procurement.
Market outlook
As of October 27, the cost support of silicon was still acceptable, forming a bottom support for the market situation, but high supply and low demand still revealed the supply and demand game. The silicon data analyst of SunSirs predicts that in the short term, the domestic silicon market will mainly fluctuate within the range, and more attention should be paid to the changes in the news on the supply and demand side.
