Fundamentals

Supply and Production: In August, domestic silicon production increased overall. According to statistics, industrial silicon production in August 2025 was approximately 386,000 tons, a 14% increase compared to environmental protection, and a 19% year-on-year decrease. From January to August 2025, cumulative industrial silicon production reached approximately 2.597 million tons, a 20% year-on-year decrease. The August increase in industrial silicon production was primarily driven by increased production capacity in Xinjiang, Yunnan, and Sichuan. The recovery of production capacity at leading enterprises in Xinjiang drove overall production growth, while Yunnan and other market regions experienced a bumper flood season, leading to an increase in overall production capacity. silicon supply is expected to continue to increase slightly in September.

Demand: As of September 8, the downstream market for silicon continued to be dominated by just-in-time purchases, and the overall demand side was generally boosted.

Future outlook:

As of September 8, the trading atmosphere in the silicon market was light and mild, and the supply and demand transmission was relatively stable. SunSirs’ silicon data analysts predict that in the short term, the domestic silicon market will mainly be in a state of consolidation, and more attention should be paid to changes in supply and demand news.
