Report Industry Investment Ratings - Industrial Silicon: Oscillating [5] - Polysilicon: Oscillating [6] - Lithium Carbonate: Oscillating [9] Core Views of the Report - Exchange position limits and repeated supply - side expectations have led to significant fluctuations in new - energy metals. For lithium in Jiangxi, without official confirmation of production cuts, caution is needed when using futures to bet on long or short positions. Options can be used to cautiously bet on potential lithium price increases. For industrial silicon and polysilicon, if there is no substantial contraction on the supply - side or significant improvement on the demand - side, prices may fall [1]. - Market sentiment for industrial silicon has cooled, leading to a sharp decline in prices; a significant drop in coal prices has caused polysilicon prices to fall; market sentiment for lithium carbonate has been volatile, with the contract hitting the daily limit down [2]. Summary by Relevant Catalogs 1. Market Views Industrial Silicon - Information Analysis: As of July 28, SMM data shows that the spot price of oxygen - passing 553 in East China is 9950 yuan/ton, and 421 is 10200 yuan/ton. The latest domestic inventory is 442,900 tons, with a month - on - month increase of 0.1%. In June, the monthly output was 327,000 tons, a month - on - month increase of 6.5% and a year - on - year decrease of 27.7%. In June, exports were 68,323 tons, a month - on - month increase of 22.8% and a year - on - year increase of 11.6%. In June, domestic photovoltaic new installations were 14.36GW, a year - on - year decrease of 38.45% [5]. - Main Logic: On the supply side, large northwest factories' previously overhauled furnaces have recently resumed production, and southwest factories are accelerating resumption. On the demand side, it is still weak year - on - year but shows marginal improvement. The reduction in the northwest still dominates short - term supply changes, but domestic supply may gradually recover. The inventory of warehouse receipts provides some support, but the speed of reduction has slowed down [5]. - Outlook: Market sentiment decline, rapid coal price drop, and further supply recovery have weakened price support, suppressing the upside space [6]. Polysilicon - Information Analysis: According to the Silicon Industry Association, the transaction price range of N - type re - feedstock is 45,000 - 49,000 yuan/ton, with an average price of 46,800 yuan/ton, a week - on - week increase of 12.2%. In May, exports were about 2,097.6 tons, a month - on - month increase of 66.2% and a year - on - year decrease of 30%. In May, imports were about 793 tons, a month - on - month decrease of 16.9%. From January to June 2025, domestic photovoltaic new installations were 212.21GW, a year - on - year increase of 107% [6]. - Main Logic: The significant decline in coal prices last Friday led to a drop in polysilicon prices. On the supply side, production capacity in the southwest is rising with the arrival of the wet season. On the demand side, although photovoltaic installations increased significantly from January to May, it has overdrafted the demand for the second half of the year, and subsequent demand may weaken [7]. - Outlook: Anti - involution policies have significantly boosted polysilicon prices. Attention should be paid to policy implementation. If the policy expectations are false, prices may fluctuate in the opposite direction [8]. Lithium Carbonate - Information Analysis: On July 28, the closing price of the main lithium carbonate contract decreased by 9.19% to 73,120 yuan, and the total contract positions decreased by 107,784 to 800,394 hands. The SMM battery - grade lithium carbonate spot price increased by 1000 yuan to 73,900 yuan/ton, and the industrial - grade increased by 1000 yuan to 71,700 yuan/ton [8]. - Main Logic: Current supply - demand drivers are weak, and market sentiment affects prices. Fundamentally, there are few changes. In the third quarter, domestic supply - demand is generally balanced, but high prices may stimulate supply. The core factors affecting the market are anti - involution sentiment and the progress of mining license issues. Before the result of mine shutdown is clear, if market sentiment recovers, prices may rise. There is high short - term uncertainty, and options are recommended for speculation [9]. - Outlook: In the short term, warehouse receipts and sentiment support prices, and prices are expected to oscillate [9].
