硅:工业硅供需过剩，多晶硅聚焦整合

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Industrial silicon is in a slow destocking phase, with supply increasing slightly at a low level and limited demand growth. Its price is expected to remain in a low - level oscillation, supported by cost at the bottom [2][44][47]. - For polysilicon, the storage platform is advancing, supply is gradually matching demand, and photovoltaic installations are maintaining high - level oscillations. The futures price is expected to stay in a high - level range, and attention should be paid to the progress of the anti - involution policy in the photovoltaic industry [2][47]. Summary by Relevant Catalogs 1. Market Review - In 2025, the silicon energy market had two phases. In the first half, due to deteriorating supply - demand and intensified competition, industrial silicon and polysilicon prices dropped below the cost line. In the second half, with the anti - involution policy, prices rebounded. The industrial silicon weighted index dropped by 36.3% from January 1st to June 4th, then rebounded but faced high - inventory pressure [8]. - Polysilicon's 06 contract rose in the first three months due to pre - Spring Festival restocking and strong terminal demand. After April, it declined because of US tariffs and reduced terminal demand. In the second half, it rebounded strongly and then maintained high - level oscillations [9]. 2. Cost - side Rigid Support and Seasonal Fluctuation of Hydropower - In the first half of 2025, industrial silicon costs collapsed due to weak demand. In the second half, with the anti - involution policy and the arrival of the wet season, raw material prices recovered. Electricity cost is crucial. Xinjiang has low thermal power costs, while Yunnan and Sichuan have seasonal cost fluctuations due to hydropower [11]. 3. Significant Decline in Production and Xinjiang's Largest Production Share - In 2025, the national industrial silicon开工率 decreased significantly. From January to November, the output was 356.98 million tons, a 19.1% year - on - year decrease. Xinjiang is the largest producer, accounting for 52.7% of the national capacity. Inner Mongolia and Gansu had increased output, while Yunnan and Sichuan decreased [11][14]. - In the future, as the dry season raises electricity prices in Sichuan and Yunnan, production will decrease in the south and increase in the north. In 2026, industrial silicon supply will rely on industry self - discipline, and overall supply pressure remains [15]. 4. Polysilicon Industry Chain - From January to November 2025, polysilicon output was 119.48 million tons, a 30% year - on - year decrease. In December, a platform company was established, planning to limit the capacity to 150 million tons [18]. - Polysilicon prices fluctuated greatly in 2025. They rose in the first quarter, declined from April to June, and rebounded in the second half due to the anti - involution policy [19]. - In 2025, from January to October, China imported 1.61 million tons of polysilicon (a 52.4% year - on - year decrease) and exported 2.02 million tons (a 33.3% year - on - year decrease). The export market is under pressure due to US sanctions [24]. - In the photovoltaic industry, although the anti - involution policy improved the situation in the second half, downstream over - capacity still exists. In 2025, domestic new photovoltaic installations are expected to reach 275GW, similar to last year, with a significant slowdown in growth. Overseas, different countries have different demand situations, and future global new installations may grow weakly [29][34]. 5. Silicone Industry Chain - In 2025, silicone prices first rebounded and then declined. After the industry's joint production - cut meeting in November, prices rose to 13,700 yuan/ton. The production profit also fluctuated accordingly [34]. - As of November 2025, the silicone DMC capacity was 344 million tons with no new capacity. Downstream demand is diversified, with traditional construction demand decreasing and emerging fields increasing. In the future, terminal demand growth is limited, and the industry plans to cut production by 30% [35]. 6. Aluminum Alloy Industry Chain - In 2025, aluminum alloy prices were relatively stable, oscillating around a high level. From January to May, the output was 15.76 billion tons, a 15.7% year - on - year increase. New energy vehicles are the main growth point for silicon - aluminum alloy demand, but future growth is limited [39]. 7. Slight Year - on - Year Decline in Exports - From January to October 2025, industrial silicon exports were 607,000 tons, a 1.2% year - on - year decrease. Overseas procurement is demand - based, and exports are expected to remain high - level oscillating next year [43].
