碳酸锂：高位强势运行，关注供需边际变化成材，重心下移偏弱运行

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core View of the Report - The report believes that lithium carbonate will operate strongly at a high level, and attention should be focused on cost and marginal changes in supply and demand [2][4] Group 3: Summary According to Related Catalogs Lithium Carbonate Futures and Spot Market - Last week, the main contract of lithium carbonate futures closed at 181,520 yuan/ton. The net short position of the main funds continued, the long - short ratio decreased month - on - month, and the warehouse receipts decreased slightly by 730 tons to 28,156 tons. The average price of SMM electric carbon was 171,000 yuan/ton. The trading market was active last week. In the spot market, upstream producers were more willing to sell, with some still holding back supply. Downstream buyers had a mix of inventory building and waiting, and scattered purchases slowed down after the price increase. Overall, transactions were mainly based on demand [2] Supply and Demand Fundamentals - Supply side: Last week, the raw material market showed a differentiated trend. Overseas lithium spodumene remained stable with a slight increase, while domestic spot lithium ore prices generally declined. The total weekly operating rate of SMM lithium carbonate was 50.99% (- 1.7%), and the operating rate of each process route decreased month - on - month due to maintenance plans. The total output was 22,217 tons (- 388 tons), with a slight decrease in supply [3] - Demand side: There was a significant structural differentiation. Last week, the output of SMM lithium iron phosphate and ternary materials decreased slightly month - on - month, and inventories were reduced. The output of SMM power cells decreased slightly. As of January 18, the penetration rate of new energy vehicle sales increased to 55.6%, and the production schedule of energy - storage cells increased slightly to support demand [3] - Inventory: Last week, the social inventory of the four - place sample of SMM increased by 2% (+ 860 tons) month - on - month, the sample weekly inventory decreased slightly by 0.7% (- 783 tons) month - on - month, and the total inventory days were 27.8 days. The inventory days of the upstream and downstream increased to 5.1 days and 9.6 days respectively, and the inventory days of other links decreased to 13.1 days, showing a significant differentiation in the inventory structure [3] Macro - policy Level - Demand side: Multiple incentives such as subsidies for car trade - ins and battery export tax rebates stimulate terminal consumption and improve macro - liquidity - Supply side: On January 15, the National Development and Reform Commission proposed to introduce management measures for the comprehensive utilization of new energy vehicle power batteries, which will improve the recycling threshold and eliminate backward production capacity, optimize the domestic supply structure in the long term, and raise the cost support center - Industrial planning: The industrial plan for Qinghai Salt Lake, the key points of the "15th Five - Year Plan" for energy storage, and a series of deployments at the Central Economic Work Conference have formed synergistic benefits to support long - term supply - demand balance. The central bank's structural interest rate cut indirectly strengthens the long - term macro - positive atmosphere [4]
