供应扰动风险仍存，新能源金属整体延续强势

Report Industry Investment Ratings - Industrial silicon: Oscillating [5] - Polysilicon: Oscillating [6] - Lithium carbonate: Oscillating and bullish [10] Core Viewpoints of the Report - Supply disruption risks still exist, and new energy metals as a whole continue to be strong. Lithium supply disruptions are expected to push up lithium prices in the short and medium term, and a bullish view on lithium prices is advisable. Silicon prices are showing an oscillating trend, and there is a risk of decline in the long term [1]. - For industrial silicon, coal prices are fluctuating, leading to continuous volatility in silicon prices. For polysilicon, market sentiment is fluctuating, resulting in wide - range price volatility. For lithium carbonate, the battle between bulls and bears continues, and the price is oscillating and correcting [2]. Summary by Relevant Catalogs 1. Market Views Industrial Silicon - Information Analysis: As of August 19, the spot price of industrial silicon fluctuated. The latest domestic inventory decreased by 0.02% month - on - month. In July 2025, the monthly output increased by 3.2% month - on - month and decreased by 30.6% year - on - year. From January to July, the cumulative output decreased by 20.0% year - on - year. In June, exports increased by 22.8% month - on - month and 11.6% year - on - year. From January to June, cumulative exports decreased by 6.6% year - on - year. In June, domestic photovoltaic new installations decreased by 38.45% year - on - year, and from January to June, cumulative installations increased by 107.07% year - on - year [5]. - Main Logic: The supply of industrial silicon continues to rise. In August, the supply pressure may continue to increase. Demand shows some improvement signs, but the inventory is expected to accumulate further [5]. - Outlook: Silicon prices will continue to oscillate in the short term, and the resumption of production by large factories will be the key [5]. Polysilicon - Information Analysis: The成交 price of N - type re - feedstock ranges from 45,000 to 49,000 yuan/ton, with an average price of 47,400 yuan/ton, a week - on - week increase of 0.42%. The number of polysilicon warehouse receipts increased. In June, exports increased by 5.96% month - on - month and decreased by 39.67% year - on - year. From January to June, cumulative exports decreased by 7.23% year - on - year. In June, imports increased by 40.3% month - on - month. From January to June, cumulative imports decreased by 47.59% year - on - year. From January to June 2025, domestic photovoltaic new installations increased by 107% year - on - year [6]. - Main Logic: Macro factors and coal price fluctuations lead to wide - range price oscillations. Supply is expected to increase in August, and demand may weaken in the future [6][8]. - Outlook: Anti - cut - throat competition policies have a significant impact on prices, and attention should be paid to policy implementation [8]. Lithium Carbonate - Information Analysis: On August 19, the closing price of the lithium carbonate main contract decreased by 1.9%, and the total position decreased by 16,876 lots. The spot price of battery - grade lithium carbonate increased by 1,100 yuan/ton, and the price of industrial - grade lithium carbonate also increased by 1,100 yuan/ton. The average price of lithium spodumene concentrate was 1,045 US dollars/ton. The warehouse receipts increased by 60 tons [9]. - Main Logic: The supply shortage caused by mine shutdowns will gradually emerge, but high prices may stimulate supply. The current domestic supply and demand are generally balanced [10]. - Outlook: The supply - demand gap caused by shutdowns is expected to keep prices oscillating and bullish [10]. 2.
