Group 1: Report Investment Rating - No information provided Group 2: Core View - The continuous rebound of alumina prices still faces triple pressures, and attention should be paid to domestic and foreign policy changes [2][3] Group 3: Summary by Directory 1. Smelting End - Focus on Domestic Policy Implementation - On December 26, 2025, the National Development and Reform Commission's article raised market expectations for alumina supply contraction policies, leading to a significant rebound in futures prices [6] - The latest weekly alumina production is 183.8 million tons, and the weekly inventory is 517 million tons, with a weekly increase of 5.7 million tons. Since July, production has remained high, and demand is close to the policy ceiling, resulting in continuous oversupply. To achieve supply - demand balance, about 2.6 billion tons/year of production capacity (2.8% of the total) needs to be cut. In 2026, with 13.4 billion tons of planned projects, the oversupply pattern may intensify [7] 2. Ore End - Focus on Guinea's Price - Support Willingness - The short - term oversupply at the smelting end is difficult to change, and the bauxite price at the cost end is the core contradiction. After the rainy season in Guinea, ore shipments increased, and the restart of the AXIS mine in early December exacerbated the bauxite oversupply. The latest sea - floating inventory of bauxite reached 15.01 billion tons, and the port inventory was 26.02 billion tons. High inventory and shrinking downstream profits drove the bauxite price down. A large Guinean mine will lower the Q1 2026 long - term price by $7.5 to $66.5/ton [14] - The reversal of bauxite prices depends on large - scale overseas supply contraction. The FOB cost of Guinean bauxite is in the range of $20 - $50/ton, and the sea freight from Guinea to China is $20 - $25/ton. The CIF price of $60 - $65/ton is expected to be a strong support, corresponding to an alumina cost support of 2450 - 2550 yuan/ton. If the price falls below this range, the Guinean government may have a strong willingness to support prices [15] 3. Futures Warehouse Receipts - Need to Be Digested - The standard warehouse receipts of alumina have a 180 - day validity period. The concentrated expiration of warehouse receipts in December, January, and February may drive the futures price to be at a discount for delivery, suppressing the short - term sharp rebound of futures prices [23]

Core Viewpoint - The alumina market is facing multiple bearish factors, leading to a weak price trend, with a focus on smelting cost support and the willingness of the smelting industry to reduce operating capacity in the future [1] Group 1: Alumina Supply and Demand - In September, China's bauxite imports reached 15.88 million tons, a year-on-year increase of 38.14%, but a month-on-month decrease of approximately 2.41 million tons, indicating a seasonal decline [1] - Cumulatively, 157 million tons of bauxite were imported in the first nine months of the year, a year-on-year increase of 32%, with Guinea accounting for 118 million tons (40.3% increase) and Australia 27.71 million tons (5.4% decrease) [1] - As of October 17, domestic bauxite port inventory was 28.69 million tons, a week-on-week increase of 653,000 tons, indicating a high supply level [1] Group 2: Alumina Production and Inventory - Domestic alumina production capacity was 112.55 million tons, with an operating capacity of 96.8 million tons, a week-on-week decrease of 1.4 million tons [1] - The weekly alumina production as of October 17 was 1.861 million tons, significantly higher than the same period last year, while electrolytic aluminum production was 852,900 tons, maintaining a supply surplus [1][3] - As of October 17, domestic alumina inventory was 4.639 million tons, with a week-on-week increase of 63,000 tons, indicating ongoing accumulation since late May [3] Group 3: Pricing and Profitability - The FOB price for Australian alumina was $323 per ton as of October 17, unchanged from late September but down $45 from late August, reflecting a weaker overseas price trend [3] - The production cost of alumina was 2,854.3 yuan per ton, with an average profit of 135.4 yuan per ton, indicating a continuous contraction in smelting profits since early August [3][6] - The expectation of further declines in alumina prices may lead to losses in high-cost regions, increasing the likelihood of voluntary production cuts in the smelting industry [3][8]
