工业硅周报：光伏行业再传“自律性”减产-20250622

Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - This week (June 13 - June 20, 2025), the spot price of industrial silicon started to stop falling and rise slightly, with the benchmark spot price reaching 7,635 yuan/ton on June 20, 2025, up 1.3% from 7,537 yuan/ton on June 13. In the futures market, the main contract of industrial silicon continued to rebound but did not break through last week's high, with the highest transaction price at 7,565 yuan/ton and the latest transaction price at 7,390 yuan/ton, a weekly increase of 1.51%. The main contract's open interest was about 305,500 lots, and trading volume increased[8]. - The supply of industrial silicon has increased. In the southwest region, some enterprises do not plan to start furnaces due to low market prices and high inventory, while a few enterprises with electricity subsidies have increased furnace starts. In the northwest region, the number of silicon furnaces has increased, mainly due to increased production by large enterprises. Overall, the total number of furnace starts has increased this week, and the market supply is sufficient, mainly in the northwest region. There is still pressure on the supply side, even though most 99 - grade silicon producers have shut down for maintenance[8]. - The demand for industrial silicon is weak. The photovoltaic industry association has reported "self - disciplined" production cuts, which is a significant negative for the end - market. Most polysilicon producers are operating at reduced loads, with mixed production schedules. The silicon powder market has few tenders, and the purchasing enthusiasm is low, so the industrial silicon price has limited room for increase. The aluminum alloy industry's demand for industrial silicon is average, and exports have decreased. In May 2025, China's industrial silicon exports were 55,600 tons, a month - on - month decrease of 8.02% and a year - on - year decrease of 22.47%. From January to May 2025, China's total industrial silicon exports were 272,300 tons, a year - on - year decrease of 10.31%[8]. - The overall production cost of industrial silicon is stable, and it is expected that the electricity cost in various regions will further decline in July. The spot profit is stable, and the futures profit has increased due to the rising futures price[8]. - This week, the standard warehouse receipt inventory was mostly in a destocking state. Silicon powder enterprises made small - scale stockpiling, but due to the rising futures price, some silicon powder factories reduced their demand. Due to the adjustment of the current spot - futures basis, there was a small release of 421 - grade warehouse receipts[8]. - Looking ahead, the overall production in the southwest region has slightly increased, downstream demand remains weak, and there is a supply - demand mismatch for different grades. It is expected that the price will still be more likely to fall than rise[8]. - The report suggests that investors should short the 2509 contract on rallies or sell out - of - the - money call options when volatility is low. Traders or upstream enterprises are advised to sell call options to protect their inventory[8]. Summary by Relevant Catalogs 1. Week - on - Week Views and Hot News - Hot News: The China Photovoltaic Industry Association is discussing "production cuts to maintain prices," with expected production cuts of 10% - 15% in the third quarter. Strict policies against "below - cost sales" and "substandard product sales" will be implemented. The National Development and Reform Commission's governance ideas for "involution - style competition" are in line with the current difficulties in the industrial silicon industry. There are rumors that Tongwei is promoting measures such as capacity acquisition and storage, and the government may introduce policies to re - position photovoltaics as energy products. In 2025, the US - China tariff war continued, and the National Energy Administration released the "2025 Energy Work Guidance Opinion"[7]. - Week - on - Week Views: As mentioned above, covering price trends, supply, demand, cost - profit, inventory, outlook, and trading strategies[8]. 2. Industry Structure - The industrial silicon industry chain includes raw materials such as petroleum coke, charcoal, and silicon ore, and downstream products such as organic silicon, polysilicon, and aluminum alloy, which are widely used in electronics, construction, and other industries[11]. 3. Spot and Futures Markets - Multiple charts show the spot prices of different grades of industrial silicon (such as 553 and 421) in different regions (e.g., Tianjin Port, Kunming Port), as well as the closing and settlement prices of continuous and active futures contracts[13][24][33]. 4. Inventory - Charts display the inventory of industrial silicon in the industry, factories, the market, and futures, with data sources from Baichuan Yingfu and the research institute[48][50]. 5. Cost and Profit - Charts show the comprehensive profit and cost of industrial silicon, electricity prices in major and non - major production areas, the prices of raw materials such as silicon ore, petroleum coke, and electrodes, and the cost and profit of polysilicon[57][61][93]. 6. Supply - Charts present the weekly and monthly production of industrial silicon, the operating rate, and monthly production capacity. There are also plans for new production capacity in multiple enterprises in Xinjiang, Yunnan, and Inner Mongolia, with a total planned new capacity of 3 million tons[110][114][117]. 7. Demand - Charts show the consumption breakdown and structure of industrial silicon, the production, price, inventory, and cost - profit of polysilicon, the price, production, cost, and profit of organic silicon, the production, inventory, and operating rate of aluminum alloy, and the production and price of solar cells[120][124][133]. 8. Import and Export - Charts display the import and export volumes of industrial silicon and polysilicon, with data from the General Administration of Customs[174][179].
