新能源及有色金属日报：原油价格回落引发氧化铝价格波动-20260401

1. Report Industry Investment Rating - Aluminium: Cautiously bullish [9] - Alumina: Cautiously bullish [9] - Aluminium alloy: Cautiously bullish [9] - Arbitrage: Neutral [9] 2. Core View of the Report - The issue in the Middle East is tending to ease, but the reduction of electrolytic aluminium production in the Middle East has actually occurred, and there is still a possibility of further production cuts. Overseas consumption has not been substantially affected, and domestic aluminium rod and alloy inventories are declining, laying the foundation for future aluminium ingot destocking. The long - term outlook for fundamentals and macro - expectations remains optimistic [6]. - The export limit policy of bauxite in Guinea is yet to be clearly introduced. Although it is not clear whether it will cause a supply shortage, the policy - oriented price limit strengthens the support for alumina prices. The alumina supply - demand situation remains in surplus, and the price fluctuates with crude oil prices in the short term and will shift upward in the long term due to raw material disturbances [7][8]. 3.
