供应扰动风险仍存，新能源金属高位宽幅震荡

Report Industry Investment Rating - Industrial silicon: Oscillating [6] - Polysilicon: Oscillating [7] - Lithium carbonate: Oscillating on the strong side [10] Core Viewpoints - The risk of supply disruptions in the new energy metals market persists, leading to high - level and wide - range oscillations. Although short - term negative impacts on supply - demand expectations have driven a sharp decline in lithium carbonate prices, supply - demand is likely to enter a phase of relative tightness, which supports lithium prices. In the medium - to - short - term, the expected contraction of supply and rising costs support new energy metal prices. For lithium, supply disruptions may continue to push up prices in the medium - to - short - term. Industrial silicon and polysilicon face high production capacity and output, with weakening supply - demand and limited upward price momentum, showing an oscillating trend. In the long - term, if there is no substantial contraction in supply or significant improvement in demand, silicon prices may decline, and high growth in lithium carbonate supply will limit the upside of lithium prices [1]. Summary by Directory 1. Industrial Silicon - Market Situation: As of August 21, the spot price of industrial silicon fluctuated. The latest domestic inventory decreased by 0.02% month - on - month. In July, the monthly output increased by 3.2% month - on - month and decreased by 30.6% year - on - year. The export volume in July increased by 8.3% month - on - month and 36.7% year - on - year. In June, domestic photovoltaic new installations decreased by 38.45% year - on - year [6]. - Main Logic: Supply is on the rise, with silicon plants in the southwest resuming production faster due to the wet - season advantage and price rebound, and some large enterprises in Xinjiang resuming production after maintenance. Demand has improved slightly, with polysilicon enterprises driving up demand, the organic silicon industry maintaining rigid procurement, and the aluminum alloy sector having stable demand. Inventory is expected to accumulate further, and market pressure needs attention [6]. - Outlook: In the short - term, silicon prices will continue to oscillate due to macro sentiment and coal prices. If large enterprises resume production intensively, prices may be further pressured [7]. 2. Polysilicon - Market Situation: As of a certain period, the成交 price of N - type re - feedstock polysilicon was in the range of 45,000 - 52,000 yuan/ton, with an average price of 47,900 yuan/ton, up 1.05% week - on - week. The number of warehouse receipts increased. In July, exports decreased by 3.92% month - on - month and 63.14% year - on - year, while imports increased by 5.11% month - on - month. From January to June 2025, domestic photovoltaic new installations increased by 107% year - on - year [7]. - Main Logic: Macroscopically, anti - cut - throat competition sentiment is fluctuating, and coal prices have declined, resulting in wide - range oscillations in polysilicon prices. In terms of supply, production capacity in the southwest has increased with the wet season, and production is expected to continue rising in August. In terms of demand, photovoltaic installations in the first five months had high growth, but it has weakened since June, and future demand may continue to decline. Overall, supply - demand is under pressure, and price fluctuations have increased [8]. - Outlook: Anti - cut - throat competition policies have significantly boosted prices. Future price trends depend on policy implementation, and if policy expectations fade, prices may reverse [9]. 3. Lithium Carbonate - Market Situation: On August 21, the closing price of the lithium carbonate main contract increased by 2.2% to 82,760 yuan, and the total open interest decreased. The spot prices of battery - grade and industrial - grade lithium carbonate decreased by 500 yuan/ton, and the average price of lithium spodumene concentrate was 950 US dollars/ton, equivalent to 79,800 yuan/ton of lithium carbonate. The number of warehouse receipts increased by 275 tons [9][10]. - Main Logic: The initial impact of the mine shutdown has subsided. The current trading focuses on actual supply - demand shortages and potential mine shutdowns. Fundamentally, a supply gap is emerging, with weekly production declining, especially for mica - based production. Imports declined significantly in July but are expected to recover in the fourth quarter. Demand is relatively stable in August and is expected to enter the peak season in September. Social inventory has decreased slightly, and warehouse receipts are gradually recovering. However, high prices may stimulate supply release. Market sentiment is volatile, and price extremes may occur [10]. - Outlook: The supply - demand gap caused by mine shutdowns is expected to keep prices oscillating on the strong side [10].
