Core Viewpoint - The silicon wafer market remains stable with no significant price fluctuations this week, as both supply and demand sides exhibit cautious behavior [1][2]. Group 1: Silicon Wafer Prices - N-type G10L monocrystalline silicon wafer (182*183.75mm/130μm) average transaction price is 1.2 yuan per piece, unchanged from last week [1]. - N-type G12R monocrystalline silicon wafer (182*210mm/130μm) average transaction price is 1.35 yuan per piece, unchanged from last week [1]. - N-type G12 monocrystalline silicon wafer (210*210mm/130μm) average transaction price is 1.55 yuan per piece, unchanged from last week [1]. - The overall market transaction volume is weak, with increased negotiation between buyers and sellers, leading to fewer purchasing orders [1][2]. Group 2: Market Dynamics - On the supply side, silicon wafer manufacturers are maintaining prices due to high raw material costs and a strong pricing stance [1]. - On the demand side, despite recent price increases in silicon materials and wafers, the price trend has not effectively transmitted to the terminal component segment, limiting acceptance of high-priced wafers [1]. - The export demand for batteries is beginning to decline due to the lack of implementation of export tax rebate policies and previous large-scale overseas order stockpiling [1][2]. Group 3: Production Rates - The overall industry operating rate shows no significant changes, with two leading companies operating at 50% and 46% respectively, while integrated companies operate between 50%-80% [1].

Price Trends - The transaction price range for n-type re-investment polysilicon this week is between 45,000 to 49,000 yuan per ton, with an average transaction price of 47,400 yuan per ton, reflecting a week-on-week increase of 0.42% [1] - The transaction price range for n-type granular silicon is between 44,000 to 45,000 yuan per ton, with an average price of 44,500 yuan per ton, showing a week-on-week increase of 0.45% [1] - The overall average price of polysilicon has slightly increased due to a significant order volume from leading companies and a reduction in inventory levels [1] Production and Supply - The number of operating polysilicon enterprises remains at 9, with an estimated domestic production of 125,000 tons in August and a potential increase to around 140,000 tons in September [2] - Despite the increase in production, polysilicon inventory is expected to rise by over 50,000 tons, exacerbating the supply-demand imbalance [2] - Some polysilicon companies are planning to implement production limits to alleviate supply pressure, which may stabilize output in September [2] Market Dynamics - The current market pricing is primarily supported by production costs, with limited impact from supply-demand fundamentals [2] - The prevailing order model in the market is largely based on dual distribution or high cost-performance procurement, indicating a lack of return to a rational market purchasing state [2] - It is anticipated that current prices are nearing a temporary peak, and without significant changes in industrial policy or terminal demand, polysilicon market prices are expected to stabilize gradually [2]

Core Viewpoint - The domestic industrial silicon market is experiencing price stability in the spot market, while futures prices have slightly declined, indicating a cautious market sentiment amid conflicting supply and demand expectations [1][2]. Price Trends - The main futures contract closed at 8600 CNY/ton, down from 8700 CNY/ton, reflecting a 1.15% decrease. The national average price remains stable at 9196 CNY/ton, with specific grades priced as follows: 553 at 8764 CNY/ton, 441 at 9174 CNY/ton, and 421 at 9875 CNY/ton. Regional prices include Xinjiang at 8840 CNY/ton, Yunnan at 10020 CNY/ton, and Sichuan at 9900 CNY/ton [1][3]. Market Dynamics - The market is currently in a contradictory state, with government policies providing positive guidance for the medium to long term, while industry expectations for short-term supply and demand remain pessimistic. Major domestic producers are gradually resuming production, with operating rates in Sichuan and Yunnan increasing by 50% and 30%, respectively. However, most production is hedged through futures contracts, limiting immediate sales volume and willingness to lower prices [1][2]. Demand Insights - Although downstream polysilicon and organosilicon companies are increasing their operating rates, their purchasing intentions are low as they anticipate lower prices for procurement [1][2]. Future Outlook - The market is expected to maintain a weak balance with both supply and demand increasing in August, leading to a slight downward trend in prices [2].
