Report Industry Investment Rating - The report does not provide an industry investment rating. Core Viewpoints - The lithium carbonate market showed a wide - range and strong - side oscillatory trend this week. In the future, the driving logic of lithium carbonate futures prices will focus on factors such as the tightness of domestic lithium ore inventory, the resumption progress of Jianxiawo, the restocking rhythm of downstream enterprises, and the production schedule of downstream in Q1. In the medium - to - long - term, the long - term value supported by the industry fundamentals remains unchanged. There are opportunities for long - position building on dips. It is recommended that investors focus on structural long - position opportunities after price corrections, anchor a reasonable valuation range based on fundamentals for batch layout, and avoid short - term volatility risks caused by blind chasing of highs [1][2]. Summary by Directory Chapter 1: Core Contradictions and Strategy Recommendations 1.1 Core Contradictions - The lithium carbonate market showed a wide - range and strong - side oscillatory trend this week. The future price of lithium carbonate futures is driven by factors including the tightness of domestic lithium ore inventory, the resumption progress of Jianxiawo, the restocking rhythm of downstream enterprises, and the production schedule of downstream in Q1. The domestic available lithium concentrate inventory is still tight. The resumption progress of Jianxiawo is a key variable. If it exceeds market expectations, it will increase lithium salt supply and suppress prices. The demand side is strong, with overall market inventory continuously decreasing, especially significant drops in downstream inventory. In December, the production schedules of downstream cathode materials and power cells increased slightly month - on - month, and market demand remained strong. However, downstream enterprises' willingness to purchase high - priced lithium carbonate decreased during the price increase period, mainly consuming their own inventory. If subsequent rigid - demand restocking needs are gradually released, the spot basis is expected to strengthen. Technically, there is significant correction pressure [1]. - Near - end trading logic (before the end of 2025): includes the tightness of domestic lithium ore inventory, the resumption progress of Jianxiawo lithium ore, and the restocking rhythm of downstream enterprises. Distant - end trading logic (after January 1, 2026): not elaborated in detail in this part [7][8]. 1.2 Industry Customer Strategy Recommendations - **Lithium carbonate futures price range**: The strong support level of the lithium carbonate main contract is 85,000 yuan/ton, with a current volatility (20 - day rolling) of 45.9% and a current volatility historical percentile (3 - year) of 78.0% [9]. - **Risk - management strategy recommendations for lithium - battery enterprises**: Different strategies are recommended for procurement management, sales management, and inventory management under different scenarios, including using futures contracts and option combination strategies, with corresponding recommended hedging ratios [9]. Chapter 2: Market Information - This week's main information includes: on December 15, the 2.4 million - ton/year mining construction project of Inner Mongolia Weilasituo Mining Co., Ltd.'s lithium - tin polymetallic ore was officially approved; on December 17, LG Energy Solution terminated a long - term battery supply contract with Ford Motor Company worth about 45.7 billion yuan; on December 18, the Ministry of Commerce stated that China and the EU are conducting consultations on the electric vehicle case; on December 19, the environmental impact assessment information of the Jianxiawo lithium ore mining project in Yichun was publicly announced [10]. Chapter 3: Futures and Price Data 3.1 Price - Volume and Capital Interpretation - **Futures trend**: This week, the lithium carbonate futures price showed an oscillatory and strengthening trend. The closing price of the weighted index contract on Friday was 111,307 yuan/ton, with a week - on - week increase of 14.28%; the trading volume was about 1.2015 million lots, with a week - on - week increase of 28.70%; the open interest was about 1.052 million lots, with a week - on - week decrease of 0.04 million lots. The LC2605 - LC2609 monthly spread showed a contango structure, with a week - on - week decrease of 720 yuan/ton; the number of warehouse receipts was 15,511 lots, with a week - on - week increase of 461 lots. In the short - term, the lithium carbonate price is in a strong - side operation, and in the long - term, it is still in an upward trend [11][12]. - **Option situation**: The 20 - day historical volatility of lithium carbonate futures showed an oscillatory correction trend in the past week, indicating that the actual price fluctuation is still at a high level. The implied volatility of at - the - money options showed an oscillatory strengthening trend, indicating that market participants expect future price fluctuations to be large. The PCR of option open interest showed an upward trend, indicating increasing bearish sentiment in the market [15][16]. - **Capital movement**: The long - position scale showed an upward trend this week [18]. - **Monthly spread structure**: The current lithium carbonate futures contract distribution still shows an overall contango structure. The resumption of production in Ningde suppresses the near - term price, and the traditional off - season in Q1 and the maintenance of material factories are expected to weaken market demand and affect the near - term price. The long - term positive logic supports the far - term price, including the growth of the domestic energy - storage industry and the increase in the penetration rate of new - energy vehicles. In the medium - to - long - term, the support for far - term contracts will be stronger than that for near - term contracts, and the contango structure is likely to deepen [20]. - **CME lithium - spodumene and lithium - hydroxide futures**: Data on CME lithium - hydroxide futures are provided, showing price changes in different months [32]. - **LME lithium - hydroxide futures**: No specific content is provided. - **Basis structure**: The basis of the lithium carbonate main contract fluctuated widely this week.
