Copper - Copper prices showed a strong fluctuation overnight, with domestic refined copper import windows briefly opening. The uncertainty surrounding the 10% global tariffs imposed by the Trump administration has increased global economic uncertainty [2][11] - LME copper inventory increased by 1,350 tons to 243,175 tons, while Comex copper inventory rose by 1,024 tons to 545,736 tons. Domestic social inventory increased by over 150,000 tons to 508,500 tons during the holiday period [2][11] - The core logic driving copper prices upward remains unchanged, with insufficient global copper mine capital expenditure leading to a supply gap, alongside increased demand from new energy and AI infrastructure. A potential short-term deep correction in copper prices could present a golden opportunity for long-term bullish positions [2][11] Nickel & Stainless Steel - LME nickel rose by 3.64% to $17,915 per ton, while SHFE nickel increased by 1.65% to 140,330 CNY per ton. LME inventory decreased by 378 tons to 287,328 tons [3][12][13] - The approved nickel ore production quota in Indonesia is between 260 million to 270 million tons, significantly lower than last year's targets. Supply tightness and maintenance issues are expected to impact production by 30,000 to 40,000 tons per month [3][12][13] - Despite a temporary weakening in demand, cost support remains solid, and ongoing disturbances in Indonesia's regulatory environment may lead to further supply concerns [3][12][13] Alumina, Electrolytic Aluminum & Aluminum Alloys - The first trading day after the holiday saw alumina prices weaken, with AO2605 settling at 2,837 CNY per ton, down 0.39%. SHFE aluminum also showed a decline, with AL2603 at 23,550 CNY per ton, down 0.55% [5][14] - Overseas alumina prices have risen, and domestic electrolytic aluminum plants are stockpiling raw materials for winter. However, social inventory pressures and the expiration of warehouse receipts are suppressing alumina price increases [5][14] - The overall space for aluminum price recovery is limited, and the extent of inventory accumulation will determine the rebound pace. Attention should be paid to overseas news and the pace of downstream resumption of work [5][14] Industrial Silicon & Polysilicon - Industrial silicon prices showed a slight increase, with the main contract at 8,410 CNY per ton, up 0.54%. However, polysilicon prices weakened, with the main contract at 47,000 CNY per ton, down 4.03% [6][15] - Supply-side support exists for industrial silicon, but demand constraints limit upward price movement. The market is currently in a wait-and-see mode regarding downstream demand recovery and new policy signals [6][15] - The market is expected to continue its weak adjustment, with potential risks if policy and demand expectations do not materialize [6][15] Lithium Carbonate - Lithium carbonate futures rose by 10.56% to 164,120 CNY per ton, with battery-grade lithium carbonate prices increasing by 8,250 CNY to 152,000 CNY per ton [7][16] - Supply-side production is expected to decrease by 16.3% in February, while demand for ternary materials and lithium iron phosphate is also projected to decline [7][16][17] - The first trading day after the holiday saw significant price increases for lithium carbonate, driven by expectations of continued inventory decline, which may provide substantial bullish support [7][16][17]
