Market Factor Analysis

Production Side: Overall Stable Operations

Xinjiang region's silicon utilization rate is approximately 69%, showing a slight increase from the previous week. Ahead of month-end, plans to restart additional furnaces in Xinjiang suggest a potential rise in utilization.

Northwest region's utilization rate remains stable at 77%, unchanged from last week.

Yunnan region's utilization rate holds steady at 65%.

Sichuan region's utilization rate is around 52%, slightly down from the previous week due to some production cuts, though most enterprises maintain steady operations; future rates are expected to remain stable.

Supply Side: Stable Current Supply with Anticipated Increase Current silicon production facilities are operating smoothly, maintaining a stable overall supply. However, with plans for new restarts in Xinjiang by late September, a moderate increase in supply is expected toward the end of the month.

Demand Side: Early "Golden September" Effects Boost Demand Slightly

Downstream polysilicon operations remain consistent, while organic silicon shows minor fluctuations; overall demand for silicon is stable.

Aluminum-silicon alloy enterprises are experiencing a modest uptick in utilization rates, driven by the initial "Golden September" seasonal effect. Improved downstream orders are supporting higher operational rates and a slight increase in raw material demand.

Outlook

The silicon market currently features moderate trading activity. With an anticipated supply increase, a looser supply environment is expected to persist. However, downstream demand is showing a narrow upward trend, with decent supply-demand transmission.

As of today, September 23, 2025, Business Society silicon analysts predict that the domestic market will likely experience range-bound oscillations in the short term. Future developments will depend on ongoing monitoring of production rates and changes in supply-demand dynamics.

Chart Representation

Conclusion

The silicon market is benefiting from stable production and early seasonal demand growth, supporting a bullish price trend. While supply is expected to increase slightly, the balance with rising demand suggests continued upward pressure in the near term. Close attention to production adjustments and demand shifts will be key to forecasting future market movements.
