Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Industrial silicon is in a slow destocking phase, with supply increasing slightly at a low level and limited demand growth. Its price is expected to remain in a low - level oscillation, supported by cost at the bottom [2][44][47]. - For polysilicon, the storage platform is advancing, supply is gradually matching demand, and photovoltaic installations are maintaining high - level oscillations. The futures price is expected to stay in a high - level range, and attention should be paid to the progress of the anti - involution policy in the photovoltaic industry [2][47]. Summary by Relevant Catalogs 1. Market Review - In 2025, the silicon energy market had two phases. In the first half, due to deteriorating supply - demand and intensified competition, industrial silicon and polysilicon prices dropped below the cost line. In the second half, with the anti - involution policy, prices rebounded. The industrial silicon weighted index dropped by 36.3% from January 1st to June 4th, then rebounded but faced high - inventory pressure [8]. - Polysilicon's 06 contract rose in the first three months due to pre - Spring Festival restocking and strong terminal demand. After April, it declined because of US tariffs and reduced terminal demand. In the second half, it rebounded strongly and then maintained high - level oscillations [9]. 2. Cost - side Rigid Support and Seasonal Fluctuation of Hydropower - In the first half of 2025, industrial silicon costs collapsed due to weak demand. In the second half, with the anti - involution policy and the arrival of the wet season, raw material prices recovered. Electricity cost is crucial. Xinjiang has low thermal power costs, while Yunnan and Sichuan have seasonal cost fluctuations due to hydropower [11]. 3. Significant Decline in Production and Xinjiang's Largest Production Share - In 2025, the national industrial silicon开工率 decreased significantly. From January to November, the output was 356.98 million tons, a 19.1% year - on - year decrease. Xinjiang is the largest producer, accounting for 52.7% of the national capacity. Inner Mongolia and Gansu had increased output, while Yunnan and Sichuan decreased [11][14]. - In the future, as the dry season raises electricity prices in Sichuan and Yunnan, production will decrease in the south and increase in the north. In 2026, industrial silicon supply will rely on industry self - discipline, and overall supply pressure remains [15]. 4. Polysilicon Industry Chain - From January to November 2025, polysilicon output was 119.48 million tons, a 30% year - on - year decrease. In December, a platform company was established, planning to limit the capacity to 150 million tons [18]. - Polysilicon prices fluctuated greatly in 2025. They rose in the first quarter, declined from April to June, and rebounded in the second half due to the anti - involution policy [19]. - In 2025, from January to October, China imported 1.61 million tons of polysilicon (a 52.4% year - on - year decrease) and exported 2.02 million tons (a 33.3% year - on - year decrease). The export market is under pressure due to US sanctions [24]. - In the photovoltaic industry, although the anti - involution policy improved the situation in the second half, downstream over - capacity still exists. In 2025, domestic new photovoltaic installations are expected to reach 275GW, similar to last year, with a significant slowdown in growth. Overseas, different countries have different demand situations, and future global new installations may grow weakly [29][34]. 5. Silicone Industry Chain - In 2025, silicone prices first rebounded and then declined. After the industry's joint production - cut meeting in November, prices rose to 13,700 yuan/ton. The production profit also fluctuated accordingly [34]. - As of November 2025, the silicone DMC capacity was 344 million tons with no new capacity. Downstream demand is diversified, with traditional construction demand decreasing and emerging fields increasing. In the future, terminal demand growth is limited, and the industry plans to cut production by 30% [35]. 6. Aluminum Alloy Industry Chain - In 2025, aluminum alloy prices were relatively stable, oscillating around a high level. From January to May, the output was 15.76 billion tons, a 15.7% year - on - year increase. New energy vehicles are the main growth point for silicon - aluminum alloy demand, but future growth is limited [39]. 7. Slight Year - on - Year Decline in Exports - From January to October 2025, industrial silicon exports were 607,000 tons, a 1.2% year - on - year decrease. Overseas procurement is demand - based, and exports are expected to remain high - level oscillating next year [43].

Report Information - Report Title: Cast Aluminum Alloy Industry Chain Weekly Report - Report Date: December 21, 2025 - Research Institute: Guotai Junan Futures Research Institute, Non-ferrous and Precious Metals Group - Analysts: Wang Rong (Chief Analyst/Assistant Director), Wang Zongyuan (Contact Person) [1] Industry Investment Rating - Not provided in the report Core Viewpoints - This week, aluminum prices first declined and then rose, with the overall center of gravity shifting upward. Cast aluminum alloy prices fluctuated at a high level, reaching a high of 21,395 on the night of Friday. On the supply side, as the weather turns cold in winter, the output of social scrap aluminum gradually decreases, the market circulation of goods tightens, and holders increase their price support and reluctance to sell. Near the Spring Festival stockpiling, some enterprises face difficulties in replenishing stocks, and their in-plant raw material inventories are low. On the demand side, the demand in the automotive industry has weakened marginally. Constrained by insufficient orders, the operating rate of downstream die-casting factories has declined, and they mainly purchase on a just-in-time basis. Overall, the shortage pattern of scrap aluminum supply remains unchanged, and there are still constraints on imports and recycling. The rigid cost provides some support for prices, but the lack of demand weakens the upward momentum of prices. In the short term, prices may fluctuate at a high level. [6] - As of December 19, the combined inventory of aluminum alloy ingot factories and social warehouses decreased by 0.06 million tons from the previous week to 13.02 million tons, and the visible inventory remained at a high level. From December 1 - 14, the retail sales of the national passenger car market were 764,000 vehicles, a year-on-year decrease of 24% and a month-on-month increase of 2%. The cumulative retail sales this year were 22.247 million vehicles, a year-on-year increase of 5%. Due to the continued boom in the automotive market in December last year, the automotive market showed weak performance this December under the high base effect, and the demand is gradually under pressure. At the same time, in some regions, the national subsidy funds are relatively scarce, which has created a large overdraft effect, and some consumers face the absence of subsidy policies. The market still has good expectations for automobile consumption next year. The Central Economic Work Conference emphasized that next year, the implementation of the "two new" policies will be optimized, which means that the national subsidy policy for consumer goods will continue to be promoted.

Report Industry Investment Rating No relevant content provided. Core Views of the Report - In 2026, the Fed will gradually slow down the pace of interest rate cuts, and the US government's vision to revitalize traditional manufacturing will restrict the growth rate of the global photovoltaic industry. China is expected to implement an expansionary fiscal policy and a moderately loose monetary policy, aiming for a good start in the 15th Five - Year Plan [3][57]. - In terms of supply, Xinjiang's production share has increased this year, while Sichuan and Yunnan's operations are generally low. New production in Inner Mongolia and Gansu has been released steadily. The number of operating furnaces has decreased, and social inventory is high. Silicon enterprises' production profits turned positive in the second half of this year. The planned new production capacity in 2026 is only 700,000 tons. Domestic cumulative production is expected to drop to 4.15 million tons this year and further to 4 million tons in 2026, a year - on - year decrease of 3.6% [3][57]. - In terms of demand, with the establishment of a new polysilicon platform company, a new sustainable industry ecosystem will be built. The production capacity of downstream battery and component markets will be further compressed, and photovoltaic terminal installations will enter a self - adaptive deceleration period. The silicone industry will enter a new balance cycle through production cuts. The aluminum alloy industry's production growth is limited due to the decline in construction and building materials demand. The overall demand growth rate of industrial silicon will continue to slow down in 2026, with a projected 3% decline in consumption growth [3][58]. - In 2026, the supply - demand structure of industrial silicon is expected to improve. The anti - involution policy will be further implemented. The photovoltaic industry will shift from high - growth to high - quality development, and the futures price center may stabilize and recover. The main operating range of industrial silicon in 2026 is expected to be between 8,000 - 11,000 yuan/ton [3][58]. Summary by Directory 2025 Market Review - In 2025, the industrial silicon market showed a trend of bottoming out and rebounding. The futures price dropped from a maximum of 11,130 yuan/ton at the beginning of the year to a minimum of 6,990 yuan/ton in early June, a decline of 37.2%. In the second half of the year, due to supply contraction and improved market sentiment, the price gradually recovered. By December 12, the main contract SI2605 closed at 8,390 yuan/ton, a significant drop of 2595 yuan/ton compared to the end of last year, a decline of 23.6%. The annual price fluctuated between 6,990 - 11,130 yuan/ton [8]. Macroeconomic Analysis Fourth Plenary Session Focuses on High - Quality Development and Domestic Demand - China's traditional manufacturing faces internal and external pressures. The "15th Five - Year Plan" proposes requirements for economic development, including promoting high - quality development, technological innovation, and the development of strategic emerging industries such as new energy and new materials. The development of artificial intelligence is also emphasized in multiple aspects [11][12]. Dual Loose Monetary and Fiscal Policies for Stable Economic Growth - China's Q3 GDP grew by 4.8% year - on - year, and the cumulative GDP in the first three quarters increased by 5.2% year - on - year. The official manufacturing PMI in November was 50.2. The economy has maintained a stable and progressive development trend, with rapid industrial growth, stable employment, and increasing resident income. In 2026, China is expected to implement an expansionary fiscal policy and a moderately loose monetary policy [14]. Fundamental Analysis Increasing Northern Production Share and Profit Turnaround in Southwest - In November 2025, China's industrial silicon production was 401,700 tons, a year - on - year decrease of 11.2%. From January to November, the cumulative production was 3.868 million tons, a year - on - year decrease of 14.7%. Xinjiang's production showed a trend of low - to - high, while Sichuan and Yunnan increased production from the dry season to the wet season. The new production capacity in Inner Mongolia and Gansu was limited. In the context of anti - involution policies, the supply side has contracted [16]. Only 700,000 Tons of New Production Capacity Planned in 2026 - As of now, China's total industrial silicon production capacity is 7.879 million tons, with an effective capacity of 7.846 million tons. The new and expanded production capacity projects from the second half of 2025 to 2026 have significantly slowed down. The planned new production capacity in 2026 is only 700,000 tons, a significant drop compared to 2025. It is expected that the total production capacity in 2026 will reach about 8.3 million tons, with a decreasing growth rate [27][30]. High Social Inventory and Stable Export Growth - As of December 12, the social inventory of industrial silicon reached 561,000 tons, a 4.6% increase from the end of last year. The exchange's average warehouse receipt inventory was between 150,000 - 180,000 tons. From January to October, the export volume was 607,000 tons, a 1% year - on - year decrease. In 2026, the domestic social inventory is expected to be high in the first half and low in the second half, and the export growth rate is expected to be 5 - 8% [36][37]. Industrial Silicon Demand Analysis New Polysilicon Platform Company and Anti - Involution in Photovoltaic Industry - From January to November 2024, China's polysilicon production was 1.206 million tons, a 27.3% year - on - year decrease.

Silicone Industry Enters a New Ecosystem - From January to November 2025, China's silicone DMC production was 2.272 million tons, a 4.6% year - on - year increase. After the industry's anti - involution meeting in November, enterprises reached a consensus on a 30% production cut and joint price support. The DMC price has rebounded from 11,050 yuan/ton to 13,600 yuan/ton. In 2026, the silicone production is expected to grow limitedly and enter a sustainable development model [44]. Limited Growth in Aluminum Alloy Production - From January to October, China's aluminum alloy production was 15.76 million tons, a 15.7% year - on - year increase. Affected by the real estate industry, the demand for aluminum processing products was weak. In the fourth quarter, there were both production increases and decreases in different regions. It is expected that the aluminum alloy production will maintain a low growth rate in 2026 [46]. Slowing Demand Growth but More Balanced Supply - Demand in 2026 - In 2026, the demand growth rate of industrial silicon will continue to slow down, but the supply - demand structure will be more balanced. The consumption growth rate is expected to decline by about 3% [47][48]. 2026 Market Outlook - In 2026, the Fed will slow down the interest rate cut, and the US government's policy will restrict the global photovoltaic industry. China will implement expansionary fiscal and monetary policies. The supply of industrial silicon will contract, and the demand growth will slow down. The supply - demand structure is expected to improve, and the futures price may stabilize and recover, with a main operating range of 8,000 - 11,000 yuan/ton [57][58].

Aluminum and Alumina - Alumina supply is in an oversupply situation, with high inventory suppressing prices. It is expected to oscillate at the bottom, with the main contract reference range of 2450 - 2700 yuan/ton. Aluminum prices are expected to be strong in the short - term but may face a pullback. The main contract of Shanghai Aluminum is expected to oscillate between 21700 - 22400 yuan/ton [12]. Zinc - Zinc prices are oscillating. The supply side is gradually shifting from loose to tight, and demand has shown structural improvement. The short - term Shanghai zinc price may be stronger than the London zinc price. Attention should be paid to the inflection point of TC and changes in refined zinc inventory, with the main contract support at 23000 - 23200 yuan/ton [15]. Copper - Copper prices are oscillating at a high level. The high price is driven by supply - inventory imbalance and macro factors. The supply side may face tightness, and the demand is being suppressed. The price is expected to have limited downside space, with the main contract support at 90000 - 91000 yuan/ton [16]. Aluminum Alloy - Cast aluminum alloy prices are oscillating strongly, with strong cost support but weak demand. The price is expected to oscillate narrowly at a high level, with the main contract reference range of 20700 - 21400 yuan/ton. Attention should be paid to the improvement in scrap aluminum supply and downstream purchasing rhythm [18]. 3.
