有色整体回落，铜价触底回升

Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Views - 沪铜: Opened higher in the morning and fluctuated throughout the day with little change in open interest. After Freeport's copper mine production cut announcement on September 24, copper prices rose with increasing positions and market attention. Downstream industries showed low acceptance of the sharp price increase, and domestic pre - holiday stockpiling ended, leading to a weaker spot premium, which suppressed copper prices. With the upcoming National Day and Mid - Autumn Festival holidays in China, overseas market volatility risks should be noted [4]. - 沪铝: Traded strongly with a slight decline in open interest. Affected by the sharp rise in copper prices last week, aluminum prices stabilized and rebounded but with weak momentum. Before the domestic holiday, there were signs of inventory reduction in electrolytic aluminum, providing support. With a loose macro - environment and an improved supply - demand balance in the peak season, aluminum prices are expected to continue to stabilize and rise [5]. - 沪镍: Traded in a range with a decline in open interest. The sector effect driven by copper prices faded, and nickel prices dropped back to the level at the beginning of last week. The long - term oversupply of nickel elements continued to suppress nickel prices, but in the short term, the slowdown in port nickel ore inventory accumulation and the reduction of SHFE nickel inventory provided support. With the overall decline of non - ferrous metals in the short term, technical support at the late - September low should be monitored [6]. 3. Summary by Section 3.1 Industry Dynamics - Copper: On September 28, eight departments including the Ministry of Industry and Information Technology issued the "Work Plan for Stabilizing Growth in the Non - Ferrous Metals Industry (2025 - 2026)". The plan aims to promote project construction in an orderly manner, avoid low - level redundant construction, and improve investment efficiency. It also emphasizes strengthening resource exploration and utilization, including implementing a new round of ore - finding breakthrough strategies, improving resource recovery and utilization rates, and promoting the comprehensive utilization of recycled resources [8][9]. - Nickel: Reuters analysis pointed out a serious disconnect in the key minerals market. Despite the expected surge in long - term demand for energy transition, the current situation is one of oversupply and weak prices. New capacity investments, especially in Indonesia, have led to a significant oversupply of nickel. As of September 29, the SMM1 electrolytic nickel price was 120,700 - 123,300 yuan/ton, with an average price of 122,000 yuan/ton, down 450 yuan/ton from the previous trading day. The average premium of Jinchuan 1 electrolytic nickel was 2,300 yuan/ton, down 50 yuan/ton [10]. 3.2 Relevant Charts - Copper: The report presents charts on copper basis, monthly spreads, domestic and overseas exchange inventories, LME copper cancelled warrant ratio, and SHFE warrant inventory [11][13][14]. - Aluminum: Charts include aluminum basis, monthly spreads, domestic social inventory, overseas exchange inventory, alumina inventory, and aluminum bar inventory [24][26][28]. - Nickel: Charts cover nickel basis, LME nickel inventory and cancelled warrant ratio, LME nickel price trend, SHFE inventory, and nickel ore port inventory [36][37][40].
