供应扰动忧虑继续，基本金属大幅走高

Report Industry Investment Rating No clear industry investment rating is provided in the report. Core Viewpoints - In the short - to - medium term, the logic of weak US dollar expectations and supply disruption concerns remains unchanged. The impact of weak real - time demand is limited, and supply disruption concerns continue to drive up base metals. Opportunities for low - buying and long - positions in copper, aluminum, and tin are worth attention. In the long term, with the expectation of potential incremental stimulus policies in China and ongoing supply disruption issues for copper, aluminum, and tin, there is an expected tightening in supply - demand, and the price trends of copper, aluminum, and tin are optimistic [1]. Summary by Related Catalogs 1.行情观点 - Copper: Supply contraction expectations are strong, and copper prices are expected to remain at a high level. The macro - environment of loose liquidity supports copper prices. On the supply - demand side, copper mine supply disruptions are increasing, and the supply of refined copper is expected to contract. Although terminal demand is weak and inventory is accumulating, the supply - demand for copper is expected to tighten [7]. - Alumina: Cost support is not very effective, and alumina prices are still under pressure. High - cost production capacity has some fluctuations, but the actual supply contraction is insufficient. The market is in a strong inventory - building trend, and raw material prices are weak. The cost support is average, and there is pressure on the upper side of the price [8][9]. - Aluminum: With optimistic capital sentiment, aluminum prices have risen significantly. The macro - outlook is positive. On the supply side, domestic operating capacity and utilization rates are high, and there are constraints on medium - term supply. On the demand side, high aluminum prices have suppressed demand to some extent, and inventory has increased. In the short term, the positive macro - outlook and expected tightening of supply - demand suggest that aluminum prices will remain in a strong - side oscillation. In the medium term, the price center is expected to rise [11][12]. - Aluminum Alloy: Cost support is strong, and the market has risen significantly. The cost support from tight scrap aluminum supply is solid. Supply is restricted by factors such as raw material shortages and profit inversions. Demand is currently based on rigid needs, and the medium - term demand is expected to improve. With cost support and stable supply - demand, prices are expected to remain in a strong - side oscillation in the short and medium terms [13][14]. - Zinc: The import ore TC has not stopped falling, and zinc prices have rebounded with the non - ferrous sector. The macro - outlook may be volatile. On the supply side, zinc ore supply is tight in the short term, and smelter profits are declining. On the demand side, it is the off - season, and demand is average. In the short term, zinc prices may remain in high - level oscillation, and there is a possibility of decline in the long - term [15][16]. - Lead: With the accumulation of social inventory, lead prices are oscillating with the non - ferrous sector. On the supply side, production has decreased due to environmental protection and other factors. On the demand side, electric bicycle orders are weak, while automobile battery orders are improving. Lead prices are expected to oscillate [17][18]. - Nickel: With repeated expectations of nickel ore quotas, the market is oscillating. Indonesia will regulate nickel production quotas in 2026. On the supply side, there is pressure. On the demand side, it is in the off - season. Nickel prices are expected to oscillate, and the actual quota implementation needs to be monitored [18][20]. - Stainless Steel: With repeated expectations of nickel ore quotas, the stainless - steel market has corrected. The cost has some support. Production decreased in December, and there may be a slight increase in January. Terminal demand is cautious, and inventory may accumulate. Stainless - steel prices are expected to oscillate, and Indonesian policy changes need to be tracked [21][22]. - Tin: With continued capital games, tin prices are running strongly. Supply risks are high. On the supply side, there are disruptions in various regions, and refined tin production is difficult to increase. On the demand side, it is expected to grow due to factors such as the semiconductor industry and new energy. Tin prices are expected to run strongly in an oscillating manner [22][24]. 2.行情监测 - Copper: No specific monitoring content is provided in the given text. - Alumina: On January 5, the spot prices in different regions were mostly stable, with a slight decline in Xinjiang. The alumina warehouse receipts were 156,917 tons, unchanged from the previous day [8]. - Aluminum: On January 5, the SMM AOO average price was 23,310 yuan/ton, up 850 yuan/ton from the previous day. The inventory of aluminum ingots and aluminum rods in the main consumption areas increased. The warehouse receipts of electrolytic aluminum on the SHFE increased. An Indonesian electrolytic aluminum project started production [11]. - Aluminum Alloy: On January 5, the price of Baotai ADC12 was 22,700 yuan/ton, up 400 yuan/ton from the previous day [13]. - Zinc: On January 5, the spot premiums of zinc in different regions were reported. As of January 5, the total inventory of zinc ingots in seven regions was 114,800 tons, up 8,700 tons from December 31, 2025. In 2025, the import of zinc concentrates increased significantly [15][16]. - Lead: On January 5, the price of waste electric vehicle batteries increased, and the price of lead ingots also rose. The social inventory of lead ingots increased, and the warehouse receipts decreased slightly [17]. - Nickel: On January 5, the SHFE nickel warehouse receipts increased, and the LME nickel inventory also increased slightly. Indonesia will regulate nickel production quotas in 2026 [18]. - Stainless Steel: The latest stainless - steel futures warehouse receipts decreased. On January 5, the spot premium of Foshan Hongwang 304 was reported [21]. - Tin: On January 5, the LME and SHFE tin warehouse receipts decreased, and the SHFE tin positions decreased. The average price of 1 tin ingots increased [24].
