Report Summary 1) Report Industry Investment Rating No relevant information provided. 2) Core Views - The finished products are expected to move in a range-bound manner, with the price center shifting downward and showing a weak trend. Attention should be paid to macro policies and downstream demand [1][3]. - The aluminum ingot price is expected to fluctuate in the short term. It is currently in the off - season with inventory accumulation, and the upward space is limited by the off - season demand pressure. Short - term support comes from the interest rate cut expectation. Focus on macro sentiment, downstream start - up, and the trend of inventory - consumption ratio [3][4]. 3) Summary by Related Catalogs Finished Products - In the Yunnan - Guizhou region, short - process construction steel production enterprises' shutdown and maintenance time during the Spring Festival is mostly in mid - to late January, and the resumption time is expected to be between the 11th and 16th day of the first lunar month, with an expected impact on the total construction steel output of 741,000 tons during the shutdown period. In Anhui Province, among 6 short - process steel mills, 1 has stopped production since January 5, and most of the others will stop production around mid - January, with a daily output impact of about 1620 tons during the shutdown [2][3]. - From December 30, 2024, to January 5, 2025, the total transaction (signing) area of newly built commercial housing in 10 key cities was 2.234 million square meters, a 40.3% decrease from the previous period and a 43.2% increase year - on - year [3]. - The finished products continued to decline in a volatile manner yesterday, reaching a new low recently. In the pattern of weak supply and demand, market sentiment is pessimistic, and the price center continues to shift downward. This year's winter storage is sluggish, providing weak price support [3]. Aluminum Ingots - Last week, the aluminum price was at a high level. The rising expectation of the Fed's interest rate cut on the macro - level boosted the basic metals, while the US imposing tariffs on India and the India - Russia aluminum cooperation agreement increased the funds' risk - aversion sentiment [2]. - In terms of supply, the operating output of electrolytic aluminum increased slightly and steadily. The total weekly cost of the electrolytic aluminum industry was 16,738 yuan/ton, and the industry still had high profits. In August, the operating capacity of alumina is expected to increase month - on - month. The bauxite shipment volume from Guinea decreased from late June to July, and the total imported bauxite from Guinea is expected to decline starting from August, while the increase in domestic bauxite supply is limited [3]. - Last week, the operating rate of domestic aluminum downstream processing leading enterprises increased slightly by 0.1 percentage points to 58.7%. Different aluminum product sectors have different operating rate trends. For example, the operating rate of primary aluminum alloy continued to rise, the aluminum cable operating rate remained stable, the aluminum profile and aluminum foil operating rates decreased slightly, and the operating rate of recycled aluminum leading enterprises remained stable [3]. - On August 11, the inventory of electrolytic aluminum ingots in domestic mainstream consumption areas was 587,000 tons, an increase of 23,000 tons compared with last Thursday and last Monday. Due to uneven arrivals, there were phased fluctuations in inventory data. In the off - season, high aluminum prices may further damage consumption, and the inventory will continue to accumulate in the short term [3].

Attention should be paid to macro - sentiment and downstream start - up, as well as macro - expectation changes, geopolitical crisis development, mine - end resumption, and consumption release [1][4] Group 3: Summary by Industry Finished Products - Yunnan and Guizhou short - process construction steel enterprises will have a shutdown and maintenance period from mid - January, with a production resumption around the 11th to 16th day of the first lunar month, affecting a total of 741,000 tons of construction steel production during the shutdown [3] - Six short - process steel mills in Anhui Province: one started to shut down on January 5, most will shut down around mid - January, and a few will shut down after January 20, affecting a daily output of about 16,200 tons during the shutdown [3] - From December 30, 2024, to January 5, 2025, the total transaction (signing) area of newly - built commercial housing in 10 key cities was 2.234 million square meters, a 40.3% month - on - month decrease and a 43.2% year - on - year increase [3] - The price of finished products continued to decline oscillatively, reaching a new low recently. In the pattern of weak supply and demand, market sentiment is pessimistic, and winter storage is sluggish, providing weak price support [3] Aluminum - In August, the operating capacity of alumina is expected to increase month - on - month, and the demand for bauxite will grow. Xinjiang Zhonghe's 2.4 million - ton alumina project is expected to be completed and put into production in the first half of 2026 [3] - From late June to July, the bauxite shipments from Guinea decreased due to the rainy season. The total bauxite imports from Guinea to China are expected to decline starting in August, and the increase in domestic bauxite supply is limited [3] - The weekly starting rate of domestic aluminum downstream processing leading enterprises increased slightly by 0.1 percentage points to 58.7%. Different sub - industries have different trends: primary aluminum alloy continues to recover but with cautious production scheduling; aluminum cable starting rate remains stable at 61.8% and is expected to rise slightly in mid - August; aluminum profile starting rate decreased slightly to 49.5%; aluminum foil starting rate decreased slightly to 68.4% and is expected to continue to shrink; the starting rate of recycled aluminum leading enterprises remains stable at 53.1% but faces downward pressure [3] - As of August 7, the inventory of electrolytic aluminum ingots in domestic mainstream consumption areas was 564,000 tons, unchanged from Monday and an increase of 20,000 tons from last Thursday.

Report Industry Investment Rating - Not provided Core Views - The finished products are expected to move in a range-bound manner, with the price center shifting downward and showing a weak trend. The aluminum ingots are expected to show a short-term strong and volatile trend, with the price mainly moving at a high level in the short term, and subsequent attention should be paid to the inventory-to-consumption trend [1][2][3] Summary by Relevant Catalogs Finished Products - The short - process construction steel enterprises in the Yunnan - Guizhou region will have a shutdown and maintenance period during the Spring Festival from mid - to late January, and the resumption time is expected to be around the 11th to 16th day of the first lunar month, with an estimated impact on the total construction steel output of 741,000 tons during the shutdown. In Anhui Province, 1 out of 6 short - process steel mills stopped production on January 5, and most of the remaining mills will stop production around mid - January, with an estimated daily impact on output of about 16,200 tons during the shutdown [1][2] - From December 30, 2024, to January 5, 2025, the total transaction (signing) area of newly built commercial housing in 10 key cities was 2.234 million square meters, a month - on - month decrease of 40.3% and a year - on - year increase of 43.2% [2] - The finished products continued to decline in a volatile manner yesterday, reaching a new low in the recent period. In the pattern of weak supply and demand, the market sentiment is also pessimistic, leading to a continuous downward shift of the price center. The winter storage this year is sluggish, providing weak support for prices [2] Aluminum - Macroscopically, after the July employment data was weaker than expected, traders bet that the number of Fed rate cuts this year would exceed previous expectations, and the US dollar weakened. The domestic new - issue Cailian Press "C50 Wind Direction Index" shows that the market expects that government bonds in July will support the year - on - year increase in new social financing, and the substitution effect may turn the new loan scale negative, but the growth rate is still high [1] - In terms of the supply side of aluminum, the port shipping in Guinea was suspended due to the previous mining rights issue, which drove the alumina futures price up slightly, but the impact on futures is relatively limited. In August, the operating capacity of alumina is expected to increase month - on - month, and the demand for bauxite will grow. Xinjiang Zhonghe's 2.4 - million - ton alumina project is expected to be completed and put into production in the first half of 2026. Affected by the rainy season, the shipping volume of Guinea's bauxite decreased from late June to July, and the total amount of bauxite imported from Guinea by China is expected to decline starting from August, while the increase in domestic bauxite supply is limited. The inventory accumulation of bauxite in China is expected to slow down gradually starting from August, and the total bauxite inventory is expected to reach an inflection point from August to September [2] - In July, the domestic electrolytic aluminum output increased by 1.05% year - on - year and 3.11% month - on - month. The operating capacity of domestic electrolytic aluminum increased slightly month - on - month in July, mainly due to the commissioning of the second - phase replacement project of Shandong - Yunnan's electrolytic aluminum. As of August 7, the inventory of electrolytic aluminum ingots in the domestic mainstream consumption areas was 564,000 tons, unchanged from Monday and up 20,000 tons from last Thursday [2] - Currently, the inventory is accumulating in the off - season, and the off - season pressure on the demand side limits the upward space. Be vigilant about the increased pricing of macro risks. The rate - cut expectation provides short - term support for prices. Pay attention to the promotion of domestic policies. The aluminum price is expected to mainly move at a high level in the short term, and subsequent attention should be paid to the inventory - to - consumption trend [3] Later Concerns - For finished products, pay attention to macro policies and downstream demand [2] - For aluminum, pay attention to changes in macro expectations, the development of geopolitical crises, the resumption of production at the mine end, and the release of consumption [4]

For aluminum, it is expected to operate in a short - term range, and attention should be paid to macro - sentiment and downstream start - up [2][3]. 3) Summary by Related Catalogs Building Materials - **Production Disruptions**: Yunnan - Guizhou short - process building steel producers' Spring Festival shutdown is expected to affect 741,000 tons of building steel output. In Anhui, 6 short - process steel mills, 1 stopped production on January 5, and most others will stop around mid - January, with an estimated daily output impact of 16,200 tons during the shutdown [1][2]. - **Real Estate Transaction**: From December 30, 2024, to January 5, 2025, the total transaction area of newly - built commercial housing in 10 key cities was 2.234 million square meters, a 40.3% week - on - week decrease and a 43.2% year - on - year increase [2]. - **Market Situation**: Building materials prices continued to decline, hitting a new low. In the supply - demand weak pattern, market sentiment is pessimistic, and winter storage is sluggish, with weak price support [2]. Aluminum - **Alumina**: As of Thursday, the total built - in capacity of metallurgical alumina in China is 110.32 million tons/year, and the operating capacity is 90.92 million tons/year. The weekly alumina operating rate increased by 2.02 percentage points to 82.41%. There are both restored and newly - added maintenance capacities in the South, and some northern alumina plants increased their operating capacity due to profit [2]. - **Electrolytic Aluminum**: In July, China's electrolytic aluminum output increased by 1.05% year - on - year and 3.11% month - on - month. The operating capacity increased slightly in July, mainly due to the start - up of the second - phase replacement project in Shandong - Yunnan. On July 31, the inventory of electrolytic aluminum ingots in major consumption areas was 544,000 tons, an increase of 11,000 tons from Monday and 34,000 tons from last Thursday. The weekly出库 volume was 92,500 tons, a significant decrease of 15,700 tons from the previous week, reaching a new low this year [2]. - **Market Outlook**: In the off - season, inventory is accumulating, and demand pressure restricts the upside. Short - term aluminum prices are expected to be range - bound, and attention should be paid to the inventory - consumption trend [3].

Group 1: Report Industry Investment Rating - Not mentioned Group 2: Core Views - The finished products are expected to move in a shock and consolidation manner [3] - Alumina spot prices are expected to gradually peak, and aluminum ingot prices are expected to be strong in the short - term range, focusing on the inventory - consumption trend [3][4] Group 3: Summary by Related Catalogs Finished Products - Yungui region's short - process construction steel enterprises' Spring Festival shutdown time is mostly in mid - to late January, with a predicted impact on building steel production of 741,000 tons during the shutdown. In Anhui Province, 1 out of 6 short - process steel mills started to shut down on January 5, and most of the rest will shut down around mid - January. The daily output affected during the shutdown is about 16,200 tons [3] - From December 30, 2024, to January 5, 2025, the total transaction (signing) area of newly - built commercial housing in 10 key cities was 2.234 million square meters, a 40.3% decrease from the previous period and a 43.2% increase year - on - year [3] - The finished products continued to decline in shock yesterday, with prices hitting a new low. In the pattern of weak supply and demand and pessimistic market sentiment, the price center continued to move down, and this year's winter storage is sluggish, providing weak price support [3] Aluminum Ingot - Macroscopically, domestic "anti - involution" policies drove industrial metals up, and the long - term tone of "promoting consumption and stabilizing growth" remains unchanged, while overseas macro uncertainties still exist [2] - Some enterprises will start maintenance in late July, which may lead to a decline in the local alumina operating capacity. Some electrolytic aluminum capacity replacement projects in the southwest region are about to be put into production, driving up the demand for alumina in the region. However, from a national perspective, alumina supply is still relatively loose, and the weekly inventory of alumina in national electrolytic aluminum plants has increased by about 25,800 tons this week, which is expected to put pressure on the spot price [3] - On July 21, the inventory of electrolytic aluminum ingots in domestic mainstream consumption areas was 498,000 tons, an increase of 6,000 tons from last Thursday and a decrease of 3,000 tons from last Monday. The reduction of aluminum rods at the end of the month led to a decrease in the expected proportion of aluminum water in July, an increase in ingot casting volume, and a significant increase in the supply of aluminum ingots. The increase in arrivals became the core driver of inventory accumulation in the off - season, but the recent inventory performance has been fluctuating [3] - The off - season inventory fluctuates, and the pressure on the demand side in the off - season limits the upward space. With the increase in macro - risk pricing, attention should be paid to the promotion of domestic policies. Driven by short - term policies, metal prices have risen. Aluminum prices are expected to be strong in the short - term range, and follow - up attention should be paid to the inventory - consumption trend [4]

Aluminum Ingots - Macroscopically, the minutes of the Fed's last meeting boosted market optimism, with most policymakers believing that interest rate cuts later this year are appropriate. However, policymakers are still worried about the inflationary pressure brought by Trump's tariffs, and only a few officials think a rate cut could happen as early as this month [2]. - As of Thursday, the total built - in production capacity of metallurgical - grade alumina in China is 110.82 million tons/year, and the total operating production capacity is 88.57 million tons/year. The weekly start - up rate of alumina has decreased by 0.05 percentage points to 79.92% compared to last week, with some enterprises in Shandong and Guangxi undergoing maintenance and a decline in operating production capacity. As of the end of June, the inventory in alumina enterprises' factories increased by 81,000 tons [3]. - Affected by factors such as the high - temperature off - season, high aluminum prices, insufficient profit margins, and weak downstream demand, the start - up rate of the aluminum processing industry decreased by 0.1 percentage points to 58.6% compared to last week [3]. - On July 10, the inventory of electrolytic aluminum ingots in the main domestic consumption areas was 466,000 tons, a decrease of 12,000 tons from Monday and 8,000 tons from last Thursday.
