Report Summary 1. Market Analysis - On June 18, 2025, the main lithium carbonate contract 2509 opened at 60,000 yuan/ton and closed at 59,880 yuan/ton, a 0.02% decrease from the previous day's settlement price. The trading volume was 181,046 lots, and the open interest was 306,885 lots, a decrease of 450 lots from the previous day. The total open interest of all contracts was 604,974 lots, a decrease of 7,855 lots from the previous day. The total trading volume of the contracts decreased by 12,486 lots from the previous day, and the overall speculation degree was 0.43. The lithium carbonate warehouse receipts were 29,967 lots, a decrease of 1,746 lots from the previous day [1]. - According to SMM data, on June 18, 2025, the price of battery - grade lithium carbonate was 59,900 - 61,000 yuan/ton, and the price of industrial - grade lithium carbonate was 58,350 - 59,350 yuan/ton, both remaining stable from the previous day. The lithium carbonate market still shows a pattern of oversupply, with the supply side having relatively sufficient available quantities and the demand side being relatively weak. Downstream material enterprises have low procurement willingness and mainly replenish inventory on a just - in - time basis [1]. 2. Inventory - According to the latest SMM statistics, the spot inventory is 133,500 tons, including 57,700 tons in smelters, 40,700 tons in downstream enterprises, and 35,200 tons in other inventories [2]. 3. Strategy - Overall, the fundamentals are weak, but there are still many positions in the near - month contracts, and many warehouse receipts have been cancelled, resulting in certain market games. Attention should be paid to the risks caused by position reduction and delivery games. If there is a significant rebound, short - selling hedging can be considered at an appropriate time. - For single - side trading, sell on rallies for hedging; for inter - period, inter - variety, spot - futures, and options trading, no strategies are proposed [3].

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The overall supply - demand of lithium carbonate remains in excess, but the warehouse receipts have been continuously decreasing recently. Attention should be paid to the downstream's willingness to accept warehouse receipts after the 07 contract warehouse receipts are cancelled, and there may be some short - term games. The fundamental situation is weak, and there is a possibility of a decline in the consumer side in the future. Hedging opportunities brought by delivery games can be focused on, and upstream enterprises can choose the opportunity to sell and hedge at high prices [1]. 3.

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The spot prices of industrial silicon and polysilicon have stabilized, and the futures market has rebounded this week. The supply side is under pressure, and cost support has weakened recently. With the approaching of the wet season in the southwest, there is a possibility of production resumption. The demand side is mainly based on rigid procurement, and consumption remains relatively weak. Polysilicon may further reduce production, and organic silicon enterprises face high cost pressure. The overall industry inventory and warehouse receipt pressure are still relatively high, and attention should be paid to the production resumption in the southwest wet season and the impact of macro - sentiment [2] - The recent polysilicon futures market is affected by the game between weak fundamentals and warehouse receipt delivery, resulting in intensified market fluctuations. The increase in warehouse receipts yesterday was significant, and attention should be paid to the sustainability of this increase [6] 3. Summary by Related Catalogs Industrial Silicon Market Analysis - On May 15, 2025, the industrial silicon futures price showed a weak and volatile trend. The main contract 2506 opened at 8450 yuan/ton and closed at 8410 yuan/ton, a change of - 30 yuan/ton (- 0.36%) from the previous settlement.

The price of East China oxygen - passing 553 silicon was 9000 - 9200 yuan/ton, 421 silicon was 9700 - 10300 yuan/ton, Xinjiang oxygen - passing 553 silicon was 8200 - 8400 yuan/ton, and 99 silicon was 8200 - 8400 yuan/ton. The prices of mainstream silicon in many other regions also remained stable, while the price of 97 silicon decreased in some cases [1] - The consumption side showed signs of improvement. The domestic high - temperature rubber downstream and terminal enterprises started to purchase. The main reason was that the volume of foreign trade orders increased due to the reduction of trade war tariffs, the domestic downstream production started to increase, the willingness to purchase raw materials strengthened, and the trading volume recovered [1] Strategy - Not provided in the content Risk - Not provided in the content Polysilicon Market Analysis - On May 15, 2025, the main contract 2506 of polysilicon futures maintained a wide - range fluctuation, opening at 38100 yuan/ton and closing at 37920 yuan/ton, a change of - 0.68% from the previous trading day.
