镍：纯镍累库与矿端矛盾博弈，中期波动率或增加不锈钢：短线供需与成本博弈，钢价震荡运行

Report Industry Investment Rating - Not provided in the content Core Views - Nickel: The contradiction between pure nickel inventory accumulation and mine - end issues may increase medium - term volatility, and short - term prices may continue to oscillate within a range [4] - Stainless steel: Short - term supply - demand and cost factors are in play, steel prices will oscillate, and long - term buying at low prices has better cost - effectiveness [5] - Industrial silicon: Market sentiment has cooled significantly, and attention should be paid to the downward driving force of the market [27] - Polysilicon: Upstream inventory is accumulating, and attention should be paid to the policy implementation time [27] - Lithium carbonate: The increase in imported ore has slowed down the destocking of lithium carbonate, and prices will oscillate within a range [61] Summary by Related Catalogs Nickel and Stainless Steel Market Conditions - Nickel: The Shanghai nickel futures price closed at 121,380 yuan/ton, with a weekly decline of 1,610 yuan/ton; the stainless steel futures price closed at 12,840 yuan/ton, with a weekly decline of 90 yuan/ton [12] Fundamental Analysis - Nickel: Indonesian nickel mine issues have increased market concerns, while global refined nickel inventory has increased steeply. The supply of pure nickel is increasing while demand is weak, and the price is under pressure [4] - Stainless steel: Demand is suppressed by tariff pressure and weak real - estate consumption, while supply is expected to increase. The surplus has narrowed, but the upstream inventory is still high, and the steel price lacks upward momentum but has limited downside space [5] Inventory Changes - Refined nickel: Chinese refined nickel social inventory decreased by 959 tons to 40,440 tons, while LME nickel inventory increased by 1,680 tons to 230,124 tons [7] - Nickel - stainless steel: SMM nickel - iron inventory decreased by 14% month - on - month to 28,652 tons, and stainless steel factory and social inventories showed different trends [7] Market News - Indonesia plans to shorten the mining quota period, and some nickel - iron smelting plants have suspended production due to losses. China has suspended a non - official subsidy for importing copper and nickel from Russia [8][9][11] Industrial Silicon and Polysilicon Market Conditions - Industrial silicon: The futures price has fallen from a high, and the spot price has risen. The SMM - reported Xinjiang 99 - silicon price is 9,000 yuan/ton (up 200 yuan/ton week - on - week) [27] - Polysilicon: The futures price first fell and then rose, and the spot price remained stable. The futures price closed at 52,700 yuan/ton on Friday [27] Fundamental Analysis - Industrial silicon: Supply: The weekly output decreased slightly, and the inventory decreased slightly. Demand: Downstream polysilicon and organic silicon support consumption, while the aluminum alloy and export markets are stable [28] - Polysilicon: Supply: The short - term weekly output remains high, and the upstream inventory is accumulating. Demand: The silicon wafer production is expected to decrease, and the next restocking may occur in mid - October [29][30] Market Outlook - Industrial silicon: Market sentiment will decline, and the price may test the cost line of Xinjiang small factories. It is recommended to short at high prices, with an expected price range of 8,500 - 9,100 yuan/ton next week [31][32] - Polysilicon: Policy expectations have cooled, and the market has returned to fundamentals. It is recommended to wait and see, with an expected price range of 49,000 - 52,000 yuan/ton next week [32] Lithium Carbonate Market Conditions - The lithium carbonate futures price oscillated within a range. The 2511 contract closed at 72,880 yuan/ton, down 1,080 yuan/ton week - on - week, and the spot price rose 100 yuan/ton to 73,600 yuan/ton [61] Fundamental Analysis - Supply: The weekly output reached a new high of 20,516 tons, and the Australian ore shipment increased significantly [62] - Demand: The domestic energy - storage market has exceeded expectations, and the cathode materials are accumulating inventory [62] - Inventory: The weekly inventory decreased to 136,800 tons, and the destocking speed has slowed down for three consecutive weeks [62] Market Outlook - The price will oscillate within a range. It is expected that the futures price will be between 70,000 - 76,000 yuan/ton. It is not recommended for arbitrage, and upstream factories are advised to increase hedging [63][64][66]
