1. Report's Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - The alumina futures price accelerated its decline in December due to high production, expired warehouse receipt delivery difficulties, high inventory, and falling ore prices. The overseas ore supply is the decisive factor for the future price trend [11]. - The alumina spot price is under pressure due to high production and continuous inventory accumulation. The oversupply situation is difficult to reverse without large - scale production cuts [11]. - After the rainy season, the bauxite shipping will gradually resume, and the ore price is expected to decline. The alumina smelting capacity surplus pattern is difficult to change in the short - term, but the current price is approaching the cost line of most manufacturers, and the subsequent production cut expectation is increasing. It is recommended to wait and see in the short term. The reference operating range of the domestic main contract AO2601 is 2450 - 2700 yuan/ton [12]. 3. Summary by Directory 3.1 Monthly Assessment - As of December 5, the alumina index fell 7.36% from October 31 to 2607 yuan/ton.

Price Dynamics - Alumina prices are under significant pressure, nearing the industry's average cost line, which may lead to increased expectations for production cuts among alumina producers due to compressed industry profits [4][9]. - The overall supply-demand balance for alumina remains loose, with high inventory levels, suggesting limited further downside for prices due to strong cost support [9].

1. Report Industry Investment Rating - No relevant content provided. 2. Core Views of the Report - Alumina production remains at a high level, and with the gradual inflow of imports, supply pressure persists, and price pressure on alumina remains significant. However, the alumina futures price has approached the cost line, and as the spot price continues to decline, the loss - making production capacity increases, showing support at the low - price level. The market's willingness to short further is insufficient, and the downward space for alumina is limited, with an expected weak oscillation. Attention should be paid to the situation of concentrated production cuts, when alumina may rebound [2][6]. 3.

The national weighted - average price of the spot market was reported at 2921 Yuan/ton on Friday, a decrease of 35 Yuan/ton from the previous week. - In terms of bauxite, the tight supply of domestic ore continued this week. In the northern region, the supply was tightened due to rainfall, and enterprise ore inventories were at a low level. In the southern inland, the mine operating rate remained low, the market spot circulation was limited, and the ore inventory in alumina plants was consumed, with prices remaining stable overall. Imported ore supply and demand parties were still waiting and watching regarding prices, and there was no obvious adjustment in spot ore prices. - On the supply side, alumina supply changed little. The roasting capacity of an alumina enterprise in Henan fluctuated in the short term, with a limited actual impact on production. As of October 23, China's alumina production capacity was 114.8 million tons, the operating capacity was 95.7 million tons, and the operating rate was 83.36%. - On the consumption side, the operating capacity of the electrolytic aluminum industry remained stable.

The rainy - season impact in Guinea continues, and rainfall has increased significantly compared with previous years. Floods have occurred in many places in Guinea, affecting ore road transportation and port operations to varying degrees, which has a certain impact on China's import volume, but the current supply of imported ore is sufficient, and prices are stable. On the supply side, the operating capacity of alumina has limited changes. Recently, an enterprise in Henan has short - term production cuts in roasting capacity, but the actual impact on production is limited. On the consumption side, the operating capacity of the electrolytic aluminum industry remains stable. Enterprises mainly purchase through bidding, and some aluminum plants in the northwest have started winter storage, mostly with price - pressured transactions. The warehouse receipt inventory decreased by 5 tons to 221,000 tons this week, and the factory warehouse inventory remained at 0 tons. Overall, alumina production remains at a high level, and with the gradual inflow of imports, supply pressure persists, and price pressure on alumina remains significant. However, the alumina futures price has approached the cost line, and as the spot price continues to decline, the loss - making production capacity increases, showing support at the low - price level. The market's willingness to short further is insufficient, and the downward space for alumina is limited, with an expected weak oscillation. Attention should be paid to the situation of concentrated production cuts, when alumina may rebound [6]. 3.4 Industry News - According to data from China Customs, as of September 2025, China's total bauxite imports in 2025 reached 157.637 million tons. In September, the total import of bauxite was about 15.88 million tons, of which about 10.493 million tons were imported from Guinea, showing a slight impact of the rainy season in Guinea. In Australia, the import level was relatively stable, with 3.74 million tons of bauxite imported. - Alcoa recently released its Q3 2025 earnings report.
