1. Report Industry Investment Rating - The rating for the alumina industry is "Oscillating" [1] 2. Core Viewpoints of the Report - The alumina supply has little change after NIMBA Mining initiated the ship transfer procedure. The alumina price has a theoretical downward space, but over - speculation is not advisable. The industry is in an over - supply stage, and a bearish approach can be taken if there is a price rebound [15] 3. Summary by Relevant Catalogs 3.1 Alumina Industry Chain Weekly Overview - **Raw Materials**: Domestic ore prices remained stable last week. Shanxi 58/5 bauxite was priced at 700 yuan/ton, Henan 58/5 at 658 yuan/ton, and Guizhou 60/6 at 596 yuan/ton. After the rainy season in Shanxi and Henan, some mines are resuming production, but environmental controls in the north will reduce output. The supply of domestic ore is hard to improve in the short term. Guinea ore is priced at 71 - 72 dollars/dry ton, while downstream enterprises' purchase intention is at 69 - 70 dollars/ton. NIMBA Mining has initiated a 200,000 - ton ore ship transfer, and about 1.5 million tons of port inventory is to be exported. Some inland mines in Guinea will increase shipments in November. Newly - arrived ore was 3.845 million tons, including 2.793 million tons from Guinea and 1.052 million tons from Australia. The shipping price from Guinea to China is 23.5 dollars/ton [12] - **Alumina**: The spot price of alumina decreased last week. The ALD northern comprehensive price was 2800 - 2860 yuan/ton, down 5 yuan/ton; the domestic weighted index was 2837.5 yuan/ton, down 33.7 yuan/ton. The import port price was 2820 - 2880 yuan/ton, unchanged. Electrolytic aluminum plants are starting winter storage, and alumina enterprises are mainly fulfilling long - term contracts. The Australian alumina is priced at about 320 dollars/ton, and the cost to northern Chinese ports is about 2828 yuan/ton, with the northern theoretical import profit dropping to about - 26 yuan/ton. The domestic full - cost of alumina is 2819 yuan/ton, and the real - time profit is 89 yuan/ton. Some enterprises' roasting was suspended due to pollution warnings, while some increased production slightly. The national alumina production capacity is 114.62 million tons, with 96.85 million tons in operation, an increase of 100,000 tons from last week, and the operating rate is 84.5% [13] - **Demand**: Domestically, Xinjiang Tianlong Mining stopped 27 electrolytic cells due to pollution warnings, affecting about 20,000 tons of production capacity. Xinjiang Tianshan Aluminum plans to start 60 electrolytic cells on November 21, 2025, with a production capacity of about 66,000 tons. The domestic operating capacity of electrolytic aluminum is 44.233 million tons, a decrease of 20,000 tons from last week. Overseas demand remained unchanged, with the operating capacity at 29.551 million tons [14] - **Inventory**: As of November 6, the national alumina inventory was 4.218 million tons, an increase of 88,000 tons from last week. The inventory of electrolytic aluminum enterprises increased, the bagged inventory of alumina enterprises decreased, the northern port inventory increased temporarily, and the inventory in other places also increased [14] - **Warehouse Receipts**: The registered warehouse receipts of alumina on the SHFE were 253,654 tons, an increase of 16,487 tons from last week [15] 3.2 Weekly Key Event Summaries in the Industry Chain - **Rise in Australian FOB Price and Decrease in Import Profit**: As of November 7, the Australian alumina price was about 320 dollars/ton, up 4 dollars/ton from October 31. The cost to northern Chinese ports is about 2856 yuan/ton, up 28 yuan/ton. The domestic market declined slightly, and the northern theoretical import profit dropped to about - 26 yuan/ton. Due to overseas production cuts and upcoming Indonesian capacity, there is still pressure on overseas alumina prices [16] - **Profit and Loss of Alumina Enterprises and Production Expectations**: The alumina spot price has been falling for three months. Based on the October average price, about 28.95 million tons of the total 98.25 million tons of operating capacity of 39 alumina enterprises are in full - cost loss, accounting for 29.47%. The cash - cost loss capacity is 3.45 million tons, accounting for 3.51%. Losses are mainly in enterprises in Shanxi, Henan, Shandong, and Guizhou [16] - **Roasting Furnace Maintenance of an Alumina Enterprise in Hebei**: Affected by environmental controls, a large - scale alumina enterprise in Hebei plans to stop 2 roasting furnaces for maintenance from 18:00 on November 3 and resume on November 8. It had stopped 2 furnaces in late October due to pollution warnings and resumed on October 31 [16] 3.3 Key Data Monitoring of the Upstream and Downstream of the Industry Chain - **Raw Materials and Cost**: The report provides data on domestic and imported bauxite prices, domestic bauxite port inventory, port shipments of major bauxite - importing countries, sea - floating inventory, domestic caustic soda and thermal coal prices, and alumina production costs in different provinces [17][19][23] - **Alumina Price and Supply - Demand Balance**: It includes data on domestic and imported alumina prices, domestic electrolytic aluminum spot price, the futures price ratio of electrolytic aluminum to alumina on the SHFE, and the weekly supply - demand balance of alumina [34][38][41] - **Alumina Inventory and Warehouse Receipts**: Data on electrolytic aluminum plants' alumina inventory, alumina plants' inventory, domestic alumina yard/terminal/in - transit inventory, total social inventory, port inventory, and SHFE alumina warehouse receipts and positions are presented [44][47][49]

Group 1: Report Industry Investment Rating - No information provided in the content Group 2: Core Viewpoints of the Report - Alumina prices are under pressure due to supply - demand surplus, with potential production cuts in November. If production cuts occur, prices may rebound; otherwise, they will remain under pressure. Overall, the price trend is to sell on rebounds next year [3][99] - The shortage of global electrolytic aluminum is more prominent overseas. Macro - and micro - factors will drive the upward trend of aluminum prices to continue. In November, domestic demand may support prices, and the import loss of aluminum ingots is expected to narrow [4][103] Group 3: Summary According to the Table of Contents 1. Preface Summary - **Alumina**: Due to supply - demand surplus, prices are falling. The November spot long - term settlement price may approach the cash cost of high - cost capacity, leading to potential production cuts. If production cuts reduce the surplus, prices may rebound to around 3000 yuan/ton; otherwise, they will be under pressure. Next year, new projects will be put into production, so the overall strategy is to sell on rebounds [3] - **Electrolytic Aluminum**: The global shortage is mainly overseas. With overseas production cuts and improving domestic demand, aluminum prices are expected to rise. The recommended strategies include unilateral trading (alumina oscillating between 2800 - 3000 yuan, aluminum oscillating strongly between 21000 - 21800 yuan), arbitrage (long SHFE aluminum and short LME aluminum), and option trading (wait - and - see) [4] 2. Alumina Low - price Pressure on Cash Cost and November Supply - side Production Cut Expectations - **Raw Material End**: Domestic bauxite supply is tight, with stable prices but few transactions. Imported bauxite prices are theoretically under pressure, but spot transactions are scarce. The price of Guinea bauxite is around 72 - 73 dollars/dry ton. In September 2025, China imported 1588 million tons of bauxite, a year - on - year increase of 37.5% [7][10][11] - **Alumina Price and Production**: As of late October, the national alumina production capacity was 11462 million tons, and the operating capacity was 9765 million tons. In October, the domestic alumina supply - demand surplus was 33 million tons (considering downstream inventory) or 17 million tons (based on social inventory). The average full cost of alumina in September was 2863 yuan/ton, with an average profit of 179 yuan/ton. In November, pay attention to production cuts due to high - cost capacity approaching cash cost and the impact of heavy - pollution weather [22][23][36] - **Import and Export**: In September 2025, China exported 24.6 million tons of alumina (a month - on - month increase of 36.5% and a year - on - year increase of 82.3%) and imported 6 million tons (a month - on - month decrease of 36.4% and a year - on - year increase of 61.7%). The net export was 18.6 million tons [31] 3. Macro - and Micro - Factors Driving the Rise of Aluminum Prices - **Macro Factors**: In October, the overseas macro - market sentiment was first depressed and then improved. The expected further reaching of tariff agreements between the US and other countries and the Fed's interest - rate cut expectation will support LME aluminum prices, but the US government shutdown may bring uncertainty [41][46] - **Electrolytic Aluminum Supply - side Changes**: - **Overseas**: There are both increases and decreases in overseas electrolytic aluminum production capacity. Some projects are in the process of being put into production, while some factories have reduced production due to accidents or power - supply issues. For example, the Icelandic electrolytic aluminum plant reduced production by about 21 million tons, and the Mozambique plant may reduce production by 37 million tons in March 2026 [51][52] - **Domestic**: As of late October, the domestic electrolytic aluminum production capacity was 4523.2 million tons, and the operating capacity was 4441.4 million tons. The profit of electrolytic aluminum remains high, and capacity replacement is ongoing. In September, the average full cost of electrolytic aluminum was 15977 yuan/ton. In September, the import of aluminum ingots was 24.68 million tons, and the export was 2.9 million tons [61][62][63] - **Inventory and Consumption**: - **Domestic**: At the end of October, the total social inventory of aluminum ingots and aluminum rods was 91.13 million tons. It is expected that the inventory will decline in November - December, and low inventory will support prices. The export profit of aluminum products is increasing, and consumption is expected to be resilient [66] - **Overseas**: The LME inventory is stable, and the spot is mostly at a premium. The global shortage of aluminum is more prominent overseas, and low inventory supports LME aluminum prices [69] - **Domestic Terminal Consumption**: - **New Energy Demand**: The production of photovoltaic modules is still relatively low year - on - year, with limited impact on aluminum demand. The use of aluminum in transportation is expected to increase year - on - year, and the use of aluminum in the power sector is also growing. The State Grid's investment in 2025 will exceed 650 billion yuan, and the sample capacity of domestic aluminum rods has increased [73][76][79] - **Traditional Industries**: The demand for aluminum in the real - estate industry is still weak, and the production of household appliances in November is expected to decline year - on - year. In September, the export of aluminum products was 87.01 million tons, and the impact of tariffs on international trade is gradually weakening [81][91][94] 4. Future Outlook and Strategy Recommendations - **Alumina**: Low prices are pressuring high - cost capacity. In November, there are expectations of production cuts. Next year, new projects will be put into production, so the overall strategy is to sell on rebounds. The cost in November can refer to that in September - October [99] - **Electrolytic Aluminum**: Macro - and micro - factors will drive the rise of aluminum prices. Overseas supply shortages will support prices, and domestic demand is resilient. In November, the import loss of aluminum ingots is expected to narrow, and the export of aluminum products is expected to increase [103]

Group 1: Report Industry Investment Rating - The investment rating for the alumina industry is "Oscillation" [1] Group 2: Core Viewpoints of the Report - The domestic ore supply has tightened, and the spot price of alumina has risen slightly. The alumina market is currently in a state of slight oversupply, and short - term price trends are expected to oscillate. It is recommended to approach it with an oscillatory mindset in the short term [1][15] Group 3: Summary by Directory 1. Alumina Industry Chain Weekly Overview - **Raw Materials**: Domestic ore prices remained stable last week. In Shanxi, Shandong, and Guizhou, the prices of different - grade bauxite were stable. In Shanxi, inspections continued, and in Henan, rainfall limited mining, leading to supply shortages and firm prices. In Guangxi, illegal mining inspections were strengthened. Imported bauxite long - term agreement prices were between $74 - 75 per dry ton, and shipments might decrease in the second half of the third quarter. Newly - arrived ore was 4.436 million tons, with 3.555 million tons from Guinea and 0.594 million tons from Australia. The shipping cost from Guinea to China dropped to $18.5 per ton [12] - **Alumina**: The spot price of alumina rose slightly last week. In the domestic market, the ALD northern comprehensive price and the domestic weighted index increased. The import port price remained flat. Market transactions were average. Overseas, 30,000 tons of alumina were traded in Western Australia. The domestic alumina production capacity increased slightly, with a construction capacity of 112.92 million tons, an operating capacity of 93.55 million tons (up 400,000 tons from last week), and an operating rate of 82.9% [3][13] - **Demand**: Domestically, Guizhou Huangguoshu Aluminum increased production by 20,000 tons to 100,000 tons. The domestic electrolytic aluminum operating capacity was 44.103 million tons, an increase of 20,000 tons week - on - week. Overseas demand remained unchanged, with an electrolytic aluminum operating capacity of 29.571 million tons [13] - **Inventory**: As of July 3, the national alumina inventory was 3.162 million tons, an increase of 25,000 tons from last week. Electrolytic aluminum enterprises' alumina inventory increased, with different inventory trends among various entities. Alumina enterprises' inventory was at a low level, port inventory fluctuated significantly, and delivery inventory decreased [14] - **Warehouse Receipts**: There were 21,314 tons of registered alumina warehouse receipts on the Shanghai Futures Exchange, a decrease of 9,005 tons from last week. The domestic futures price oscillated last week. The bauxite price in Guinea was stable in the third quarter, and the domestic alumina supply was slightly in surplus, suppressing the price. It is recommended to view alumina from an oscillatory perspective in the short term [15] 2. Summary of Key Events in the Industry Chain during the Week - On July 5, 30,000 tons of alumina were traded in East Australia at a FOB price of $363 per ton from Gladstone Port for shipping in early August [16] - On July 4, 10,000 tons of alumina were traded in Guangxi at an ex - factory price of 3,250 yuan per ton. Supply in the local market was tight due to production cuts and maintenance [16] - On July 2, 300 tons of alumina were traded in Henan at an ex - factory price of 3,150 yuan per ton, purchased by a trader for delivery to a northwest aluminum plant [16] 3. Monitoring of Key Data for the Upstream and Downstream of the Industry Chain - **Raw Materials and Cost**: This section includes data on domestic and imported bauxite prices, domestic bauxite port inventory, shipping volume from major bauxite - importing countries, sea - floating inventory, domestic caustic soda and thermal coal prices, and alumina production costs in different provinces [17][19][24] - **Alumina Price and Supply - Demand Balance**: It covers domestic and imported alumina prices, domestic electrolytic aluminum spot prices, the futures price ratio of electrolytic aluminum to alumina on the Shanghai Futures Exchange, and the weekly supply - demand balance of domestic alumina [31][33][39] - **Alumina Inventory and Warehouse Receipts**: It involves the alumina inventory of electrolytic aluminum plants, alumina plants, domestic alumina in storage/on the platform/in transit, port inventory, total social inventory, and the quantity and holding volume of alumina warehouse receipts on the Shanghai Futures Exchange [41][44][49]

Report Industry Investment Rating - Not provided in the content Core Viewpoints - The US economy shows some resilience with the May unemployment rate in line with expectations and non - farm payrolls slightly exceeding expectations, leading to a reduced expectation of interest rate cuts and a slight rebound in the US dollar index. The ongoing US - Japan trade negotiations have no results, and internal US uncertainties are increasing, which is expected to have a significant impact on the global economy [6]. - Overseas tariff policies and US internal instability factors are increasing, which will likely affect global assets. In the short term, the market will return to fundamentals. Domestically, demand is entering the off - season, putting upward pressure on prices in the medium term. However, the social inventory is decreasing and at a low level, and spot merchants are eager to support prices, with high premiums providing strong support for the market. It is expected that the main 07 contract will fluctuate within the range of 19,600 - 20,200 yuan/ton, with a higher probability of short - term weakness. Attention should be paid to the long - short game around 20,000, and industrial players are advised to purchase as needed [8]. Alumina - Industry Fundamental Summary Supply - In May, the in - production capacity increased by 2.1 million tons month - on - month, and the operating rate rose slightly. The domestic arrival volume of ore remained normal, and the departure volume from Guinea was also normal [9]. - In April 2025, China's alumina net exports were 249,300 tons, a slight month - on - month decrease, with 13 consecutive months of net exports. Import shifted to a small profit [9]. Demand - The in - production capacity of electrolytic aluminum increased slightly and remained at a high level, so the short - term demand for alumina was relatively stable [9]. Profit - The current smelting cost of alumina is 3,046 yuan per ton, with a profit of 269 yuan per ton. The cost increased slightly, and the profit decreased slightly. The latest price of caustic soda is 3,730 yuan/ton, a weekly increase of 30 yuan/ton [9]. Suggestion - The impact of Guinea's ore - end policy on sentiment has eased, and the market has fallen after a surge. It is recommended to take a long - position in the 09 contract on dips and a short - position in the 07 contract on rallies. The position volume of the variety is 450,000 lots, with 320,000 lots in the 09 contract. Although the funds have flowed out compared to the previous week, the volume is still relatively high, and large fluctuations are expected [9]. Electrolytic Aluminum - Industry Fundamental Summary Supply - In May 2025, China's electrolytic aluminum in - production capacity was 44.139 million tons, a year - on - year increase of 2.65% and a month - on - month increase of 40,000 tons. The capacity utilization rate was 98.22%, a slight month - on - month increase [45]. - In April, China's electrolytic aluminum net imports increased significantly both year - on - year and month - on - month. The net import in April was 236,800 tons, a year - on - year increase of 30,600 tons and a month - on - month increase of 23,700 tons [54][56]. - In April, China's scrap aluminum imports were 190,000 tons, a year - on - year increase of 5.5% and a month - on - month increase of 7,000 tons. The cumulative scrap aluminum imports from January to April were 697,000 tons, a year - on - year increase of 6.7% [63]. Demand - In April 2025, China's aluminum product output was 5.764 million tons, a year - on - year increase of 0.3%. The cumulative output this year was 21.117 million tons, a year - on - year increase of 0.9% [65]. - In April 2025, China's aluminum alloy output was 1.528 million tons, a year - on - year increase of 10.3%. The cumulative output this year was 5.76 million tons, a year - on - year increase of 13.7% [68]. Cost - The domestic alumina spot price declined slightly from the high level and remained volatile at a high level, while the overseas spot price was stable in the short term [71]. - The pre - baked anode price was 5,675 yuan/ton, a weekly decrease of 15 yuan/ton, about 0.26% [74]. - The price of dry - process aluminum fluoride was 9,710 yuan/ton, a weekly decrease of 230 yuan/ton, about 2.3%. The price of cryolite was 8,520 yuan/ton, a weekly increase of 260 yuan/ton, about 3.15% [77]. Profit - The current electrolytic aluminum smelting cost is 17,021 yuan/ton, a weekly decrease of 6 yuan/ton. The overall profit is 3,279 yuan/ton, a weekly decrease of 54 yuan/ton [80]. - The current import loss of electrolytic aluminum is 1,132 yuan/ton, a weekly slight narrowing of 5 yuan/ton [83]. Inventory - As of June 5, the social inventory of electrolytic aluminum was 503,000 tons, a weekly decrease of 6,000 tons and a decrease of 17,000 tons within the week. The inventory is at a historically low level, and the de - stocking speed has slowed down [86]. Basis - The spot price of aluminum in East China is in the range of 20,100 - 20,340 yuan/ton, a weekly decrease of 60 yuan/ton. The spot price fluctuates with the market, and as downstream demand enters the off - season, the upward pressure on prices increases, and the spot premium decreases slightly. However, due to the low social inventory, spot merchants still have the will to support prices [92].

Core Viewpoint - The commodity market is experiencing mixed trends, with aluminum oxide futures showing a notable increase while black building materials continue to decline. The recent three consecutive days of gains in aluminum oxide futures have drawn significant attention, reflecting market concerns over production cuts and future ore supply [1][2]. Group 1: Market Dynamics - After the May Day holiday, many aluminum oxide-related enterprises are undergoing maintenance, leading to production disruptions. For instance, a 1 million ton capacity line in Shanxi has halted due to ore supply issues, and another 800,000 ton capacity line in Guangxi will be under maintenance for 15 days [2]. - The aluminum oxide futures market is transitioning to the 2509 contract, with traders focusing on the anticipated production cuts during the rainy season in Guinea [2]. - Despite the rise in futures prices, domestic aluminum oxide spot prices have remained relatively stable, with an average price of 2895.86 yuan/ton as of May 8, 2025 [2]. Group 2: Supply and Demand Factors - The aluminum oxide industry has seen its production capacity increase from 82.45 million tons at the beginning of the year to over 90 million tons, outpacing demand growth and contributing to price declines [3]. - Social inventory of aluminum oxide has increased from 3.7 million tons at the start of the year to 4 million tons by late April, but has recently decreased to 3.946 million tons due to production cuts [5]. - The dependency on imported bauxite is high, with approximately 75% of China's bauxite sourced from abroad, primarily Guinea [6]. Group 3: Price Trends and Projections - The price of aluminum oxide is heavily influenced by supply and demand dynamics, with a significant surplus expected in the market due to rapid capacity expansion [9]. - The cash cost of aluminum oxide production is a critical indicator, with current costs around 2669 yuan/ton, which may serve as a short-term price support level [11]. - Future price movements are anticipated to face resistance around the 3000-3100 yuan mark, with potential downward pressure if bauxite prices continue to decline [12].

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - The alumina futures price is expected to maintain a weak oscillation in the short - term due to new production pressure, despite the rebound driven by supply disruptions in Guinea and the overseas price increase. The spot price has stopped falling in the short - term but is unlikely to rebound significantly. The supply of bauxite is becoming more abundant, and its price may continue to face downward pressure. The alumina supply is in a long - term surplus, while the demand from electrolytic aluminum remains stable. The export window remains closed, and short - term trading is recommended to be on the sidelines. The reference operating range for the domestic main contract AO2505 is 2650 - 2950 yuan/ton [10][11][12]. 3. Summary by Directory 3.1 Week - on - Week Assessment - As of 3 p.m. on April 18, the alumina index oscillated narrowly, falling 0.92% to 2800 yuan/ton this week, with positions decreasing by 21,000 lots to 410,000 lots. The basis widened, with the Shandong spot price at a premium of 66 yuan/ton over the main contract. Most regional spot prices stopped falling, except for slight drops in Guizhou and Shandong. The social inventory increased by 0.6 tons to 400.1 tons, and the SHFE warehouse receipts decreased by 0.4 tons to 28.77 tons. The bauxite supply is loosening, and its price may decline. The alumina production decreased by 3.7 tons to 164.4 tons this week due to smelter maintenance. The electrolytic aluminum operating capacity and operating rate increased in March [10][11]. 3.2 Spot and Futures Prices 3.2.1 Spot Price - Most regional alumina spot prices stopped falling this week, with Guizhou and Shandong prices dropping 15 yuan/ton and 10 yuan/ton respectively. Short - term stability is due to smelter maintenance and overseas price rebound, but significant rebounds are unlikely [19]. 3.2.2 Futures Price and Basis - As of April 18, the alumina index oscillated narrowly, falling 0.92% to 2800 yuan/ton this week, with positions decreasing by 21,000 lots.

1. Report Industry Investment Rating - The investment rating for the alumina industry is "Oscillation" [1] 2. Core Viewpoints of the Report - Alumina prices continue to decline, and the industry is facing cost - profit pressure. However, with the reduction in operating capacity and potential demand recovery, the price may gradually enter a bottom - grinding stage [13][15] - The supply of bauxite is affected by policies and market factors, with domestic prices in a downward trend but limited downside space, and overseas supply facing uncertainties [2][12] 3. Summary by Directory 3.1 Alumina Industry Chain Weekly Overview Raw Materials - Domestic ore prices are in a downward channel.
