Chang Jiang Qi Huo· 2025-12-08 05:25
1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints - In 2026, alumina prices are expected to decline with reduced volatility due to a more relaxed ore supply and a slightly oversupplied production capacity [1][29][92] - The growth rate of domestic electrolytic aluminum production will slow down significantly as the operating capacity approaches the ceiling, and imports are expected to increase to offset the supply - demand gap. The downstream demand for aluminum is undergoing a structural transformation [2][45][92] - The price of aluminum alloy will still be pegged to the price of aluminum in 2026, but its seasonal performance will be weaker than before [3][53][93] - The price of aluminum and aluminum alloy is expected to show an upward trend in 2026, driven by factors such as global economic recovery, new - energy transformation, and power construction [3][93] 3. Summary by Relevant Catalog 3.1 2025 Market Review - In 2025, aluminum prices showed a trend of oscillating upward breakthrough, divided into three stages: oscillating upward from January to mid - March, oscillating downward from mid - March to early April, and oscillating upward from early April to November. The price fluctuations were affected by various factors such as policies, tariffs, inventory changes, and macro - events [6][7][8] 3.2 Supply Side 3.2.1 Bauxite - Domestic bauxite production increased slightly in 2025, with a growth rate of 5.2% from January to November. However, production was restricted in some areas due to safety and environmental regulations. Imported bauxite increased significantly, with imports from January to October reaching 171 million tons, a year - on - year increase of 30.4%. The price of imported bauxite decreased due to increased supply. There were some disturbances in the supply from Guinea, and the political situation in Guinea may affect future supply policies [14][16][18] 3.2.2 Alumina - In 2025, alumina production increased, with output from January to October reaching 78.222 million tons, a year - on - year increase of 9.56%. The price first declined, then rebounded, and then fell again. New production capacity was limited in 2025, mainly from Guangxi Huasheng Phase II, Shandong Chuangyuan New Materials, and Hebei Wenfeng. In 2026, new overseas production capacity will be mainly in India, Indonesia, and Vietnam. Alumina production capacity is expected to be slightly oversupplied in 2026, and prices will be determined by cost, showing an oscillating downward trend [22][24][29] 3.2.3 Electrolytic Aluminum - In 2025, the built - in and operating capacity of domestic electrolytic aluminum increased slightly, with production from January to October reaching 36.8908 million tons, a year - on - year increase of 2.57%. Many enterprises resumed production due to improved profitability, while some enterprises carried out technical upgrades and maintenance, resulting in production cuts. New production capacity mainly came from Shuangyuan Aluminum, Chalco Qinghai, and others. In 2026, new domestic production capacity will mainly come from Huomeihongjun Zhalv Phase II and Tianshan Aluminum. Overseas production capacity increased in 2025, mainly in Indonesia, Russia, and other countries, and is expected to increase by 1.8 million tons in 2026. The growth rate of domestic electrolytic aluminum production will slow down significantly in 2026, and imports are expected to increase [30][35][45] 3.2.4 Aluminum Alloy - Although the import of scrap aluminum was liberalized in 2024, there was no significant increase in 2025 due to factors such as the cancellation of export tax rebates, tariff differences, and tightened trade policies in some countries. The production of recycled aluminum alloy increased steadily, and the listing of aluminum alloy futures promoted production. After the listing of the futures, the production of cast aluminum alloy increased significantly, suppressing the price difference between ADC12 and A00, and the seasonal effect was weakened [48][50][52] 3.3 Demand Side 3.3.1 Real Estate - In 2025, the real estate market continued to decline. In 2026, the real estate market is expected to continue to bottom out, and the demand for aluminum in the real estate sector will continue to decrease. However, urban renewal and affordable rental housing will support part of the aluminum demand [54][56][58] 3.3.2 Infrastructure - In 2025, the issuance of local government special bonds increased, but part of the funds was used for debt repayment, resulting in a slowdown in infrastructure investment growth. The investment in the power grid reached a new high. In 2026, with the increase in special bond quotas and the promotion of power grid construction, the demand for aluminum in infrastructure is expected to increase by 5% [59][61][69] 3.3.3 Automobile - In 2025, the automobile market had good production and sales performance, with new - energy vehicle penetration exceeding 50%. In 2026, although consumption policies are expected to be strengthened and export demand is optimistic, factors such as the reduction of new - energy vehicle purchase tax exemption and the implementation of new battery standards may lead to flat demand for aluminum in the automobile industry [70][72][75] 3.3.4 Photovoltaic - In 2025, the new installed capacity of photovoltaic increased significantly in the first half of the year but decreased sharply after June due to the "430 New Policy" and "531 New Policy". In 2026, the new installed capacity of domestic photovoltaic is expected to decline significantly, and although the overseas new installed capacity is expected to grow at a rate of 25%, the overall demand for aluminum in the photovoltaic industry is expected to decrease [76][79][82] 3.3.5 Aluminum and Aluminum Product Exports - In 2025, the net export of aluminum products decreased, mainly due to the cancellation of export tax rebates and the imposition of tariffs. The export of aluminum products increased. In 2026, due to the continuation of policies and the strengthening of the domestic aluminum price, the net export of aluminum and aluminum products is expected to decline [83][85][86] 3.4 Inventory and Supply - Demand Balance - In the first half of 2025, aluminum inventories decreased significantly, while in the second half, they increased seasonally. In 2026, the domestic electrolytic aluminum market is expected to have a shortage of 100,000 tons [88][90][91] 3.5 2026 Outlook - Alumina prices are expected to decline with reduced volatility; the growth rate of domestic electrolytic aluminum production will slow down, imports will increase, and downstream demand will transform; the price of aluminum alloy will be pegged to aluminum with weaker seasonality; the price of aluminum and aluminum alloy is expected to rise [92][93]

Core Viewpoint - The aluminum oxide futures market has experienced a significant decline, with the main contract closing at 2590 yuan/ton, marking a new low and falling below the cash production cost line for most domestic producers [1][2]. Group 1: Market Conditions - The recent drop in aluminum oxide prices has created a "double kill" scenario, where both futures and spot prices have plummeted, leading to widespread losses for market participants [1]. - The current futures price is below the marginal cash cost range of 2850 to 2950 yuan/ton, with total costs estimated between 3070 and 3170 yuan/ton, indicating that approximately 90% of domestic production is unprofitable [2]. - The inventory situation is critical, particularly in Xinjiang, where the delivery warehouse is nearing full capacity, exacerbating supply-demand imbalances and putting further downward pressure on prices [2]. Group 2: Demand Dynamics - The demand for aluminum oxide is constrained by the overall capacity limits in the downstream electrolytic aluminum industry, with only limited incremental demand expected [3]. - The opening of import channels has led to an influx of aluminum oxide, further intensifying domestic supply pressures [3]. Group 3: Industry Outlook - The decline in prices is prompting concerns about potential production cuts among high-cost aluminum oxide producers, particularly in northern regions [4]. - Falling prices below cash costs are leading to increased likelihood of "passive production cuts" as smelters face profitability issues [5]. - The market is transitioning from a previously tight balance to structural oversupply, driven by both domestic price pressures and uncertainties in overseas markets [6]. - Future challenges include rising production capacity, new investments, and increased imports, which may counteract any potential positive impacts from policy measures aimed at limiting capacity [7].

1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core Viewpoints of the Report - The current labor market in the United States is weak, and the decline in ADP employment data in November has further increased the expectation of the Federal Reserve to cut interest rates. The economic sentiment in China is generally stable, and attention should be paid to the upcoming Central Economic Work Conference. In the aluminum industry, the supply of domestic bauxite is tight, while the overseas supply may be relatively loose. The operating capacity of alumina is slightly decreasing at a high level, and the price may fluctuate at a low level. The production of electrolytic aluminum in October increased year - on - year, but the downstream processing start - up rate is decreasing. The inventory of domestic and foreign exchanges has declined, and the social inventory has slightly increased. In terms of the market outlook, it is recommended to be bullish on aluminum prices after the correction, and for aluminum alloy, wait for the opportunity to buy on the correction [5][11][14]. 3. Summary by Directory 3.1 Report Summary - The latest ADP employment data shows that private enterprises in the United States reduced 32,000 jobs in November, the largest decline since March 2023, far lower than the market expectation of an increase of 10,000. The US manufacturing PMI index in November decreased by 0.5 points to 48.2, continuously below the boom - bust line of 50 for nine months, with the new order index and backlog orders showing significant contractions. Domestically, the economic sentiment is generally stable. In the aluminum industry, the operating capacity of domestic electrolytic aluminum has little change, the supply side is stable, and the demand side shows a weakening trend. The start - up rate of downstream processing enterprises has decreased, and the social inventory has slightly increased. It is recommended to be bullish on aluminum prices after the correction, paying attention to the results of the Federal Reserve's interest rate cut in December and the subsequent interest rate cut path prediction [5]. 3.2 Multi - empty Focus - **Bullish factors**: The operating capacity of domestic electrolytic aluminum has little change; the expectation of the Federal Reserve to cut interest rates is rising; the overseas aluminum supply - demand tension still exists [8]. - **Bearish factors**: The downstream's fear of high prices has resurfaced, and the social inventory has turned to a slight accumulation; the terminal market has entered the off - season [8]. 3.3 Data Analysis - **Bauxite**: In October, the domestic bauxite output was 4.7723 million tons, a month - on - month decrease of 2.2% and a year - on - year decrease of 6.9%.
