铝&氧化铝产业链周度报告-20250831

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Aluminum is expected to experience a weekly - level consolidation, with the price center likely to move upward. The aluminum market has entered the "traditional consumption peak season", and downstream demand is a mixed bag. The overall aluminum price still needs to break through the convergent pattern, and both the unilateral direction and volatility tend to the long - side. [3] - For alumina, attention should be paid to the spot sales pressure, and there may still be room for the price to decline. The overall price center of alumina has moved down this week, and the spot sales pressure is increasing, which may still drag down the AO futures market. [4] 3. Summary According to Relevant Catalogs 3.1 Transaction End: Spreads, Volume, and Open Interest - Term Spreads: This week, the A00 spot premium weakened, while the alumina spot premium strengthened. The average SMM A00 aluminum premium changed from 30 yuan/ton to - 20 yuan/ton, and the average SMM A00 aluminum (Foshan) premium changed from - 30 yuan/ton to - 75 yuan/ton. The Shandong alumina premium to the current month changed from 67 yuan/ton to 126 yuan/ton, and the Henan alumina premium to the current month changed from 87 yuan/ton to 166 yuan/ton. [9] - Monthly Spreads: The near - month spread of SHFE aluminum has widened. [10] - Open Interest: The open interest and trading volume of the SHFE aluminum main contract decreased slightly, while the open interest of the alumina main contract increased slightly and is at a historical high, and its trading volume decreased slightly. [12] - Open Interest - to - Inventory Ratio: The open interest - to - inventory ratio of the SHFE aluminum main contract declined, and the open interest - to - inventory ratio of alumina continued to fall and is at a historically low level. [17] 3.2 Inventory: Bauxite, Alumina, Electrolytic Aluminum, and Processed Materials - Bauxite: As of August 29, the port inventory of imported bauxite increased by 90,000 tons compared with last week, and the port inventory days remained basically the same. As of August, the bauxite inventory of 43 sample enterprises across the country increased by 1.19 million tons month - on - month, and the bauxite inventory days in alumina plants remained stable. As of August 29, the weekly bauxite shipments from Guinea and Australia ports decreased, and the floating inventory also decreased. As of August 22, the bauxite out - port volume from Australia's Weipa + Gove ports increased slightly, while that from Guinea's Boffa + Kamsar ports decreased slightly, and the bauxite arrival volume decreased. [22][27][28] - Alumina: The national total alumina inventory continued to increase. As of Thursday (August 28), the national alumina inventory was 3.497 million tons, an increase of 74,000 tons compared with last week. The alumina inventory in plants, at electrolytic aluminum plants, and at ports increased, while the inventory in yards/platforms/in - transit decreased slightly. [36][48] - Electrolytic Aluminum: The electrolytic aluminum inventory continued to increase. As of August 28, the weekly inventory of aluminum ingot social inventory increased by 31,000 tons to 610,000 tons. [49] - Aluminum Rod: This week, the downstream aluminum rod spot inventory and in - plant inventory showed a divergent trend, and the out - port volume decreased. [55] - Aluminum Profiles & Plate - Foil: As of July, the finished - product inventory ratio of SMM aluminum profiles remained basically flat, while the raw - material inventory ratio decreased significantly. The finished - product inventory ratio of SMM aluminum plate - foil decreased slightly, and the raw - material inventory ratio also decreased significantly. [57] 3.3 Production: Output, Capacity, and Capacity Utilization - Bauxite: In August, the domestic bauxite supply measured by the SMM caliber decreased slightly. Imported bauxite supply is still an important increment for the total domestic bauxite supply. In July, the bauxite output in Shanxi, Henan, and Guangxi measured by the Steel Union caliber increased slightly, while in August, the bauxite output in these three provinces measured by the SMM caliber decreased. [62][65] - Alumina: The alumina capacity utilization rate remained stable. As of August 29, the total operating capacity of alumina across the country was 94.6 million tons, with a week - on - week decrease of 1.7 million tons in the weekly operating capacity. This week, the domestic metallurgical - grade alumina output was 1.847 million tons, a decrease of 5,000 tons compared with last week, and it is still at a high level in recent years. The short - term supply - loose pattern of alumina fundamentals has not been reversed. [69] - Electrolytic Aluminum: As of July, the operating capacity of electrolytic aluminum remained at a high level, and the capacity utilization rate remained high due to profit repair. As of August 21, the weekly output of electrolytic aluminum measured by the Steel Union caliber was 848,300 tons, an increase of 400 tons compared with the previous week, and the output level remained at a six - year high. With the arrival of the consumption peak season, the aluminum - water ratio showed a seasonal increase, and the ingot - casting volume of aluminum ingots was expected to decrease month - on - month, reducing the supply pressure. [73] - Downstream Processing: This week, the output of aluminum plate - foil increased slightly by 3,800 tons compared with last week. The output of recycled aluminum rods decreased by 1,860 tons week - on - week, while the output of aluminum rods increased by 6,000 tons week - on - week. The operating rate of leading downstream processing enterprises increased slightly. The operating rate of primary aluminum alloy, aluminum profiles, and aluminum cables increased slightly, while the operating rate of recycled aluminum alloy remained flat. [75][77][82] 3.4 Profit: Alumina, Electrolytic Aluminum, and Processed Materials - Alumina: This week, the alumina profit decreased slightly, and the profit of metallurgical - grade alumina measured by the Steel Union caliber was 390.1 yuan/ton, maintaining a good level of smelting profit. The alumina profits in Shandong, Shanxi, and Henan remained stable, and the profit performance in Guangxi was better than that in other regions. [89] - Electrolytic Aluminum: The electrolytic aluminum profit remained at a high level. However, the current complex global macro - economic situation, overseas geopolitical conflicts, and changing trade policies have increased uncertainty factors, interfering with market expectations. [99] - Downstream Processing: The processing fee of aluminum rods decreased slightly by 10 yuan/ton week - on - week, and the downstream processing profit remained at a low level. [100] 3.5 Consumption: Import Profit & Loss, Export Profit & Loss, and Apparent Demand - Import Profit & Loss: The import profit & loss of alumina and SHFE aluminum has widened. [108] - Export: In July 2025, the export of unforged aluminum and aluminum products increased slightly by 52,000 tons month - on - month. The export profit & loss of aluminum processed materials showed a divergent trend, and the export demand for aluminum products was hindered by trade policy adjustments. [110][112] - Apparent Consumption Volume: The transaction area of commercial housing decreased, and the monthly output of automobiles decreased month - on - month. [117]
