新能源及有色金属日报：氧化铝交割升水调整-20250905

1. Report Industry Investment Rating - Aluminum: Cautiously bullish [8] - Alumina: Neutral [8] - Aluminum alloy: Cautiously bullish [8] 2. Core Viewpoints of the Report - For electrolytic aluminum, the macro - environment drives the rise in non - ferrous metal prices, with a weak spot market. Supply remains stable, consumption shows improvement, and the inventory build - up rate slows, with expected destocking. Overseas consumption is strong, and there is an increased expectation of interest rate cuts [6]. - Regarding alumina, the adjustment of Xinjiang delivery premium may create arbitrage opportunities. The cost side has support, and although the supply - demand balance is slightly in surplus, considering multiple factors, the price should be treated neutrally [6][7]. - For aluminum alloy, scrap aluminum supply is tight, but production profit has recovered, indicating consumption recovery. The increase in social inventory is due to the transformation of invisible inventory to visible inventory [7]. 3.
