碳酸锂大跌9%，封跌停板，后市怎么看？

Core Viewpoint - The recent sharp decline in lithium carbonate prices is attributed to multiple factors, including market sentiment, policy adjustments, and demand expectations for the electric vehicle sector [6][7][10]. Market Overview - On November 21, the main contract for lithium carbonate futures on the Guangzhou Futures Exchange hit the limit down, with a drop of 9%, closing at 91,020 yuan/ton [2]. - Spot prices also fell significantly, with battery-grade lithium carbonate at 92,900 yuan/ton, down 2,500 yuan/ton from the previous day [4]. Trading Volume and Positioning - Trading volume for the main lithium carbonate futures contract decreased to 1,595,600 lots, while open interest fell by 23,500 lots to 479,600 lots, indicating a strong willingness among investors to liquidate positions at high levels [4]. Policy Adjustments - The Guangzhou Futures Exchange announced adjustments to trading fees and limits for lithium carbonate futures contracts, effective November 24, 2025, which may have contributed to the cooling market sentiment [5][7]. Supply Side Analysis - The supply of lithium remains tight, with processing fees for lithium salts at low levels (18,000-19,000 yuan/ton) due to fierce competition among producers [8]. - Current production rates are not expected to increase significantly, as lithium salt plants are operating at nearly full capacity [8]. Demand Side Analysis - Demand for lithium carbonate has been strong, particularly in the energy storage sector, with expectations for global energy storage shipments to reach 560 GWh this year and 780 GWh next year, reflecting a 40% year-on-year growth [9]. - However, concerns about potential demand weakness in the first quarter of next year due to earlier demand pull-forward have emerged [10]. Market Sentiment and Future Outlook - Market sentiment remains cautious, with expectations of a potential decline in demand for electric vehicles due to subsidy reductions in China [10]. - Analysts suggest that while the current supply-demand balance is tight, any recovery in production from key lithium mines could lead to a more relaxed supply situation in December [17][18].
