运费引发的连锁反应给予氧化铝支撑

1. Report Industry Investment Rating - Unilateral: Aluminum: Cautiously bullish; Alumina: Cautiously bullish; Aluminum alloy: Cautiously bullish. Arbitrage: Neutral [8] 2. Core View of the Report - The freight - induced chain reaction provides support for alumina. Overseas supply disruptions and high LME premiums are favorable for aluminum prices. In the long - term, aluminum price increase is still expected. The short - term freight fluctuations will provide strong cost support for alumina [1][6][7] 3.

Qatar's electrolytic aluminum plant has suspended further production cuts after a 40% cut. Bahrain Aluminum has cut production by 30%. The Middle East situation persists, and the Strait of Hormuz is still blocked. Overseas inventories are declining, and the LME premium is high, which is favorable for aluminum prices. Domestic: Attention should be paid to the recovery of downstream consumption. Currently, social inventories are still increasing, while aluminum rod inventories show signs of destocking due to consumption recovery. In the long - term, the supply reduction in the Middle East and rising electricity prices are expected to drive up aluminum prices [6] Alumina - Rising freight has pressured the FOB price of Guinean bauxite. Guinea may control the supply of bauxite in the market through a quota system, and the policy is expected to take effect in the next few weeks. The Strait of Hormuz blockade continues, and the risk of freight rising due to high oil prices persists. Domestically, the oversupply situation continues, and inventories are increasing. Short - term freight fluctuations will provide cost support for alumina [7]
