Group 1 - Copper prices showed a slight increase in the morning and rose further in the afternoon, reaching a peak of 93,300 yuan, closing up by 1.54% [1] - Concerns about tight supply at the mining level and potential impacts on the smelting sector have intensified, coupled with low inventories in non-US regions, providing strong support for copper prices [1] - Codelco, the Chilean state-owned copper company, has set a historical high for copper premiums to US customers, exceeding $500 per ton above the London Metal Exchange (LME) [1] Group 2 - The LME copper cancellation warrants surged by nearly 60,000 tons last week, indicating a growing supply gap outside the US, which is expected to support copper prices in the long term [1] - Despite rising copper prices, downstream purchasing willingness remains low, disrupting the pace of domestic refined copper inventory reduction [1] - Concerns about future copper supply have resurfaced due to unfavorable negotiations for concentrate and refined copper long-term contracts, along with increased maintenance shutdowns at smelting companies [1] Group 3 - The LME copper price has significantly increased, reaching new historical highs, while domestic copper prices remain stable but weaker than LME, leading to expectations of substantial exports in the first quarter [1] - Current short-term macroeconomic and fundamental issues have been overshadowed by concentrate shortages, high premiums for long-term contracts, and inventory liquidity concerns, with market sentiment shifting towards external market dynamics [1]

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - **Copper**: Overnight, both domestic and international copper prices fluctuated within a narrow range, with the loss on domestic refined copper spot imports widening. The employment market shows resilience, and the expected interest - rate hike by the Bank of Japan may put pressure on global risk assets. LME copper registered warrants are being converted into cancelled warrants, indicating tight LME inventory and a structural problem in global visible inventory. The market sentiment is evolving towards an external squeeze, and the performance may remain strong [1]. - **Aluminum**: Overnight, alumina fluctuated weakly, while Shanghai aluminum and aluminum alloy fluctuated strongly. The market's expectation of environmental production restrictions on northern alumina plants did not materialize, and new production and restarting occurred, leading to a correction in the futures market. Aluminum prices have supported demand, but the demand impulse is difficult to sustain, and the upside space depends on the bulls' response to subsequent macro - dynamics [1][2]. - **Nickel**: Overnight, LME nickel rose slightly, while Shanghai nickel fell slightly. Nickel inventory increased, and the nickel - iron stainless - steel industry chain is weak. In the new - energy industry chain, raw materials are tight, but the production of ternary precursors is expected to decline in December. It may be considered to buy at low levels, but beware of macro - disturbances and overseas industrial policy adjustments [2]. 3. Summary According to Relevant Catalogs 3.1 Research Views - **Copper**: In terms of macro, the initial jobless claims decreased significantly, and the Bank of Japan's expected interest - rate hike may impact global risk assets.

The SMM alumina price fell, and the aluminum ingot spot discount widened. The aluminum rod and aluminum alloy processing fees showed different trends. The lack of expected environmental production restrictions led to a correction in the market, and the demand impulse is difficult to sustain [1][2]. - **Nickel**: LME nickel rose 0.07%, and Shanghai nickel fell 0.03%. LME and SHFE nickel inventories increased. The nickel - iron price center decreased, and the stainless - steel inventory decreased slightly. Raw - material support in the new - energy industry chain is weakening, and the production of ternary precursors is expected to decline in December [2]. 3.2 Daily Data Monitoring - **Copper**: On December 4, 2025, the price of flat - water copper increased by 2270 yuan/ton.
