1. Report's Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The aluminum market shows a large - range oscillation tendency. After the Fed's interest rate cut in September, the macro - driving force weakens, but the US PMI stabilizes from a decline, and China's anti - involution policy continues to advance, keeping the macro - situation generally positive. In terms of supply and demand, there is an oversupply of upstream alumina and a tight balance in domestic electrolytic aluminum. In October, there is still a slight upward momentum in the peak season, and it may enter a wide - range oscillation state from November to December [5][11]. - The overall price of aluminum may be under pressure and oscillate. The macro - situation is dull, the supply is stable due to the capacity ceiling, the pre - National Day stocking demand limits the downside, but the demand gap cannot be filled by partial downstream chasing and restocking. Meanwhile, the social inventory continues to accumulate, warehouse shipments are at a low level in recent years, and the spot premium shows a discount, putting pressure on prices [11]. 3. Summary According to Relevant Catalogs 3.1 Mid - line Market Analysis - **Mid - line Trend Judgment**: The market is in a large - range oscillation. After the Fed's interest rate cut in September, the macro - driving force weakens, but the US PMI stabilizes from a decline, and China's anti - involution policy continues to advance, keeping the macro - situation generally positive. In terms of supply and demand, there is an oversupply of upstream alumina and a tight balance in domestic electrolytic aluminum. In October, there is still a slight upward momentum in the peak season, and it may enter a wide - range oscillation state from November to December. It is advisable to hold medium - term long positions below 20,000 [5]. - **Variety Trading Strategy**: - **Last Week's Strategy Review**: The support for SHFE aluminum 2511 in the coming week was about 20,800, and the resistance was about 21,400. Hold long positions with a light position [7]. - **This Week's Strategy Suggestion**: The support for SHFE aluminum 2511 in the coming week is about 20,500, and the resistance is about 20,900. Conduct short - term trading. Spot enterprises are recommended to increase inventory appropriately [8]. 3.2 Overall Viewpoints - **Aluminum Ore Market**: Recently, the price of Guinean bauxite has tightened seasonally due to the rainy - season shipping. After the rainy season ends, the ore price is expected to have a seasonal correction without unexpected events, but there is an obvious support at 70 US dollars/ton. In the fourth quarter, the domestic ore output will be marginally repaired, but the overall supply is difficult to improve significantly due to stricter environmental protection and supervision [9]. - **Alumina Market**: As of September 12, the domestic alumina production capacity was about 112.55 million tons, the operating capacity was about 96.8 million tons, and the capacity utilization rate was about 86.23% (85.21% last week), which is at a high level since 2022. Since late August, the smelting profit has slightly declined. Now the spot price has dropped to the high - marginal cost, increasing the risk of alumina plant production cuts [9]. - **Electrolytic Aluminum Production**: As of September 2025, the domestic electrolytic aluminum production capacity is approaching the policy ceiling of 45 million tons, the operating capacity is 44.1 million tons, and the operating rate is as high as 98%, with limited room for further production increase. The new production capacity in the fourth quarter only comes from 100,000 tons of Chalco Qinghai (transfer of Yunnan's quota) and a 250,000 - ton replacement project of Xinjiang Nongliushi Aluminum Industry. The net increase for the whole year is expected to be less than 500,000 tons. The domestic electrolytic aluminum output in 2025 is expected to be 43.96 - 44.5 million tons, with a year - on - year growth rate dropping to 1.5% - 2.3%. The output in the fourth quarter may remain high but is difficult to increase significantly [9]. - **Import and Export**: Currently, the theoretical loss of electrolytic aluminum imports is about 1,800 yuan/ton (about 1,400 yuan/ton last week). According to customs data, aluminum exports have generally rebounded since March this year and are currently at a relatively high level in recent years. Although the export growth rate in the second half of the year is expected to decline compared with the first half, the overall resilience is still expected [9]. - **Demand**: - **Aluminum Profiles**: The domestic aluminum profile industry's operating rate increased by 0.6 percentage points to 54.6% this week. The operating rate of construction profiles remains low, while industrial profiles have received more new orders recently in the traditional peak season of September, supporting the operating rate. Most enterprises have not determined the National Day holiday arrangements, and some enterprises in Sichuan and Shandong plan to take about 3 days off [10]. - **Aluminum Sheets, Strips, and Foil**: The operating rate of leading aluminum sheet enterprises decreased by 0.4 percentage points to 68.2% this week. In the short term, the operating rate of leading aluminum sheet enterprises is expected to remain stable or oscillate upward. The operating rate of leading aluminum foil enterprises remains stable at 71.9%, and the slowdown of leading enterprises is obvious. In the short term, supported by the peak - season effect, the operating rate of leading aluminum foil enterprises is expected to oscillate between 72% - 75% [10]. - **Aluminum Cables**: The operating rate of the aluminum cable industry remained stable at 65.2% this week. All leading manufacturers are busy. As the National Day holiday approaches, the purchasing intensity of downstream manufacturers is expected to increase further, and the operating rate is expected to rise slowly next week [10]. - **Alloys**: The operating rate of the primary aluminum alloy sector decreased by 0.2 percentage points to 57.4% this week, and the industry's production capacity release has slightly converged. Although the industry's operating rate is oscillating and adjusting in the short term, SMM still has an optimistic expectation for the peak season. The operating rate of leading recycled aluminum enterprises increased by 0.4 percentage points to 55.9% this week, mainly benefiting from the alleviation of raw material procurement pressure and the moderate recovery of orders. The short - term industry operating rate will maintain a slight upward trend, but raw material shortages and policy factors will continue to suppress the capacity recovery elasticity [10]. - **Inventory**: - **Electrolytic Aluminum**: The social inventory of electrolytic aluminum ingots is 640,000 tons, an increase of about 3% from last week and about 14% lower than the same period last year, continuing the inventory - building trend since mid - July. This week's inventory increase is mainly due to the decrease in warehouse shipments, but the inventory of electrolytic aluminum plants has decreased. The increase in electrolytic aluminum social inventory is expected to be limited in the near future. The aluminum rod inventory is 130,200 tons, basically stable compared with last week and about 9% higher than the same period last year. The LME aluminum inventory has risen again, continuing the inventory - building pattern since the end of June. As there are signs of the Russia - Ukraine war ending through negotiations, the previous market's hidden inventory is gradually becoming explicit, and the LME inventory is still likely to accumulate in the future [10][16]. - **Alumina**: The overall alumina inventory continues to accumulate, and the increase mainly comes from the inventory of electrolytic aluminum plants and alumina plants. The port inventory is still at a low level in recent years [16]. - **Profit**: - **Alumina**: The average full - cost of the Chinese alumina industry is about 2,840 yuan/ton, and the profit is about 200 yuan/ton (about 270 yuan/ton last week) [11]. - **Electrolytic Aluminum**: The average production cost of domestic electrolytic aluminum is about 17,200 yuan/ton, and the theoretical profit is about 3,600 yuan/ton (3,700 yuan/ton last week). The profit is at a relatively high level [11]. - **Market Expectation**: The macro - situation is dull, the supply is stable due to the capacity ceiling, the pre - National Day stocking demand limits the downside, but the demand gap cannot be filled by partial downstream chasing and restocking. Meanwhile, the social inventory continues to accumulate, warehouse shipments are at a low level in recent years, and the spot premium shows a discount, putting pressure on prices [11]. - **Personal View**: After the Fed's interest rate cut in September, the macro - driving force weakens, but the US PMI stabilizes from a decline, and China's anti - involution policy continues to advance, keeping the macro - situation generally positive. In terms of supply and demand, there is an oversupply of upstream alumina and a tight balance in domestic electrolytic aluminum. In October, there is still a slight upward momentum in the peak season, and it may enter a wide - range oscillation state from November to December. The aluminum price may still be under pressure and consolidate in the coming week. The support for SHFE aluminum 2511 is about 20,500, and the resistance is about 20,900 [11]. - **Key Concerns**: 1. Changes in domestic social inventory. 2. Whether there are disturbances at the Guinean ore end. 3. The implementation of China's anti - involution - related policies [11]. 3.3 Important Industry Link Price Changes - This week, bauxite prices remained stable. As the rainy season in Guinea is approaching recovery and there are frequent policy - related disturbance news, and the long - term contract price in the fourth quarter has not been finalized, the increase in the supply of imported bauxite has become the focus of the market. Coal prices rose slightly, driven by pre - holiday stocking. Under strict current production capacity control, the pit - mouth price is resistant to decline. Seasonally, the single - electricity price in Yunnan is about 0.382 yuan, and it is more likely to rise in October. This week, the alumina price continued to decline slightly. Due to oversupply and inventory accumulation, the spot price is under pressure [12]. 3.4 Important Industry Link Inventory Changes - This week, the domestic port bauxite inventory slightly rebounded, continuing to accumulate to a recent high since the beginning of 2025 and stabilizing at a high level after August. However, the bauxite inventory of alumina plants is still increasing. According to DISR's forecast, the export volume of Australian bauxite is expected to remain stable in the fourth quarter, and the domestic bauxite supply is abundant. The overall alumina inventory continues to accumulate, and the increase mainly comes from the inventory of electrolytic aluminum plants and alumina plants, while the port inventory is still at a low level in recent years [16]. 3.5 Supply and Demand Situation - **Profit**: The average full - cost of the domestic alumina industry this week is about 2,840 yuan/ton, the profit is about 200 yuan/ton (about 270 yuan/ton last week), the theoretical import profit of alumina is about 150 yuan/ton (120 yuan/ton last week); the electrolytic aluminum production cost is about 17,200 yuan/ton (about 17,500 yuan/ton last week), the theoretical profit is about 3,600 yuan/ton (3,700 yuan/ton last week); the theoretical import loss of electrolytic aluminum is about 1,800 yuan/ton (about 1,400 yuan/ton last week) [18]. - **Downstream Processing**: The operating rate of domestic leading aluminum downstream processing enterprises increased by 0.1 percentage points to 62.2% this week, 1.3 percentage points lower than the same period last year. The operating of leading primary alloy enterprises is stable, but small and medium - sized enterprises' operating rates have adjusted due to demand fluctuations; the operating rate of sampled aluminum sheet enterprises decreased slightly this week; the operating rate of aluminum cables remained stable; the operating rate of profiles increased slightly, mainly because industrial profiles are supported by orders from the automotive and photovoltaic industries; the demand for packaging foil is rigid but has limited growth; the operating rate of the recycled aluminum industry increased slightly. The weekly operating rate of downstream aluminum processing is expected to continue to increase slightly next week [22][23]. 3.6 Futures - Spot Structure - The current Shanghai aluminum futures price structure is weak [28]. 3.7 Spread Structure - This week, the spread between aluminum ingots and ADC12 is about - 2,040 yuan/ton, compared with - 1,940 yuan/ton last week. The current spread between primary aluminum and alloy is at a relatively low level in recent years, and the current spread has a moderately strong impact on electrolytic aluminum [35][36]. 3.8 Market Capital Situation - **LME Aluminum**: After remaining stable for the previous four weeks, the net long position of funds in the latest period has significantly increased, mainly related to the Fed's interest rate cut in September. According to the dot - plot, there will be two more interest rate cuts this year, and the overall market is still bullish [38]. - **SHFE Electrolytic Aluminum**: This week, the net long position of the main contract slightly declined, and both the long and short camps slightly reduced their positions; the net long position of funds mainly for financial speculation slightly reduced. The funds mainly from mid - and downstream enterprises changed from a slight net long position to a slight net short position and have been in a stalemate between long and short recently. Judging from the performance of the current main funds, the market may oscillate and be under pressure in the coming week [41].
