Report Title - Aluminum Strategy Monthly Report, May 2025 [1] Investment Rating - Not provided in the given content Core Viewpoints - In May, alumina is expected to remain in an oversupply situation. Based on the logic of marginal oversupply and a downward - moving cost center, it is advisable to short at high prices and consider bottom - fishing in stages. Attention should be paid to the impact of the resumption rhythm in the southwest on alumina inventory dynamics. The macro - risk pricing ratio remains relatively high due to the vacillating US attitude towards tariffs on China and the possible shift in Fed policies. Aluminum demand lacks resilience after a slow decline, and inventory may reach an inflection point for accumulation. Aluminum prices are expected to be weakly volatile, with the spread between June and September having room to converge. Attention should be paid to the effects of domestic stimulus policies, tariff dynamics, and the resumption progress in Yunnan [3]. Summary by Directory Price - In April, the alumina futures fluctuated weakly, with the main contract closing at 2,846 yuan/ton on the 25th, a monthly decline of 3.1%. Shanghai aluminum also fluctuated weakly, with the main contract closing at 20,030 yuan/ton on the 25th, a monthly decline of 2.2% [5]. Spread - In April, the alumina shifted from a premium of 146 yuan/ton to a premium of 26 yuan/ton, and electrolytic aluminum shifted from par to a discount of 10 yuan/ton [5]. Supply - According to SMM, it is estimated that in April, the operating capacity of domestic metallurgical - grade alumina decreased to 8,288 tons, with a production of 7.17 million tons, a month - on - month decline of 5% and a year - on - year increase of 7.4%. The operating capacity of domestic electrolytic aluminum increased to 4,390 tons, with a production of 3.57 million tons, a month - on - month decline of 3.2% and a year - on - year increase of 1.6%. The molten aluminum ratio slightly dropped to 73% [3][5]. Demand - As the peak season is approaching its end, the cable sector is showing a late - stage boost while other sectors are gradually weakening. In April, the average operating rate of aluminum downstream processing enterprises was 62.4%, a month - on - month increase of 0.25% compared to March. Among them, the operating rate of aluminum sheets and strips decreased by 1.85% to 68.65%, the operating rate of aluminum foils decreased by 2.14% to 73.43%, the operating rate of aluminum profiles increased by 0.75% to 58.88%, and the operating rate of aluminum cables increased by 5.7% to 62.2%. The processing fees of aluminum rods increased across the board by 100 - 250 yuan/ton, and the processing fees of aluminum bars were stable with some increases, with Wuxi remaining stable and other regions increasing by 20 - 160 yuan/ton [3][5]. Inventory - In terms of exchange inventory, in April, alumina inventory increased by 29,000 tons to 236,900 tons; Shanghai aluminum inventory decreased by 42,800 tons to 190,500 tons; LME inventory decreased by 53,000 tons to 423,600 tons. In terms of social inventory, alumina inventory increased by 7,000 tons to 55,000 tons; aluminum ingot inventory decreased by 169,000 tons to 658,000 tons; aluminum bar inventory decreased by 94,200 tons to 177,800 tons [3][5].

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Viewpoints - Southwest's hydropower-rich season with lower electricity prices will drive production resumption, weakening the effect of northwest production cuts. Meanwhile, the marginal improvement in downstream demand is limited. It is expected that industrial silicon will continue to bottom out in May, with the lower support coming from the cash cost line of large Xinjiang manufacturers and the upper pressure from high inventory and marginal increments. - In May, the adjustment flexibility of polysilicon production is high, and the one - way decline space is limited. It will mainly show weak range - bound fluctuations, and opportunities for the convergence of near - and far - month price spreads can be considered. Attention should be paid to whether large - scale infrastructure or mandatory photovoltaic installation assessment policies are newly introduced after the decline of distributed photovoltaics, which may trigger an oversold rebound [3]. 3. Summary by Directory 3.1 Futures Prices - In April, polysilicon futures fluctuated weakly. As of the 25th, the main contract 2506 closed at 39,390 yuan/ton, with a monthly decline of 11.67%. Industrial silicon futures also fluctuated weakly. As of the 25th, the main contract 2506 closed at 8,865 yuan/ton, with a monthly decline of 9.73% [5]. 3.2 Spot Prices - Spot prices continued to decline. The Baichuan reference price was 10,178 yuan/ton, with a monthly decrease of 502 yuan/ton. Among them, the price of non - oxygenated 553 decreased by 750 yuan/ton to 9,350 yuan/ton, oxygenated 553 decreased by 600 yuan/ton to 9,950 yuan/ton, and 421 decreased by 600 yuan/ton to 10,350 yuan/ton [5]. 3.3 Price Spreads - In April, the price spread between 553 widened, the spread between high - and low - grade products remained stable, the regional spread of 553 widened, and the regional spread of 421 widened. The industrial silicon spot changed from a discount to a premium of 2,110 yuan/ton, and the polysilicon spot discount narrowed to 65 yuan/ton [5][17]. 3.4 Supply - According to Baichuan, the estimated domestic industrial silicon production in April was 290,600 tons, a year - on - year decrease of 17% and a month - on - month decrease of 9.5%. The monthly number of open furnaces decreased by 15 to 219, and the furnace opening rate decreased by 1.88% to 27.48%. In the north, large manufacturers in Xinjiang started maintenance, with 9 new furnace shutdowns in Xinjiang, 2 in Gansu, and 3 in Inner Mongolia. In the southwest, there was no change in the operation in Yunnan, and 2 furnaces were ignited in Sichuan silicon plants. In other regions, one furnace was shut down each in Ningxia, Shaanxi, Henan, and Liaoning [3][5]. 3.5 Demand - In April, polysilicon production decreased by 6,000 tons to 96,000 tons, a year - on - year decrease of 49.3% and a month - on - month decrease of 5.9%. The production of DMC increased by 10,800 tons to 167,500 tons, a year - on - year increase of 31.7% and a month - on - month increase of 6.9%. The monthly price of P - type polysilicon remained stable at 33,800 yuan/ton, while the N - type decreased by 20,000 yuan/ton to 40,000 yuan/ton. The terminal rush - to - install subsided, the component market cooled down rapidly, downstream surplus materials were abundant, order delivery periods were postponed, and the pre - May Day stocking volume was low. The monthly price of organic silicon decreased significantly by 2,500 yuan/ton to 12,000 yuan/ton. Downstream buyers maintained a wait - and - see attitude during the tariff turmoil, with weak purchasing power. New orders from monomer plants were still mainly for essential and small - volume needs, and the overall inventory pressure increased significantly. Subsequently, they may return to the state of shutdown and maintenance [3][5]. 3.6 Inventory - On the exchange side, the overall inventory of industrial silicon decreased by 435 tons to 348,400 tons in April, while polysilicon inventory increased to 300,000 tons. In the social inventory, industrial silicon inventory increased by 1,400 tons to 409,100 tons, among which factory inventory decreased by 1,600 tons to 244,100 tons; the inventory at Huangpu Port remained stable at 52,000 tons, Tianjin Port's inventory increased by 3,000 tons to 65,000 tons, and Kunming Port's inventory remained stable at 48,000 tons. Polysilicon inventory decreased by 3,800 tons to 26,770 tons [3][5].

1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - The supply of the pig market continues to put pressure on pig prices, but the decline in the first quarter was weaker than expected. The second quarter will continue to focus on supply pressure, and there is a risk of compression in pig prices and breeding profits [3][4]. - Policy support for the corn market is nearing its end, and in the fourth quarter, it will be tested whether downstream consumption can support prices [5]. - In the first quarter of 2025, the global oilseed and fat market first rose and then fell, with the domestic market outperforming the international market. The second quarter will continue to be troubled by trade uncertainties, and attention should be paid to changes in biodiesel policies [7]. 3. Summaries According to the Table of Contents First Part: Factors Affecting the Pig Market in the Second Quarter - Pig prices in the first quarter were stronger than expected, but supply pressure still exists. The terminal demand entered the off - season after the Spring Festival, and pig prices oscillated at a low level [3][4]. - Affected by the change in the mentality of the breeding side, the price of piglets first rose, then fell, and then rose again in the first quarter [3]. - The inventory of breeding sows decreased for two consecutive months. If this trend continues, the supply pressure in the second half of the year will be substantially improved [3]. - In the first quarter, the slaughter weight of pigs first decreased and then increased. The import volume of pork decreased as domestic pig prices were at a low level [3][4]. - The breeding profit of self - breeding and self - raising decreased, while that of purchasing piglets increased. The slaughter opening rate was higher than the same period last year, but it was not driven by the increase in terminal demand [4]. - In the futures market, pig prices stabilized and rebounded in the first quarter. In the second quarter, the supply pressure of increased inventory will continue to affect spot pig prices and long - term trading sentiment [4]. Second Part: Analysis of Factors Affecting the Corn Market - From January to March, the prices of US wheat and corn first rose and then fell. Affected by weather, policy, and other factors, the CBOT grain futures prices declined jointly [5]. - The spot price of domestic corn rose with the futures price. By the end of March, the average domestic corn spot price increased by 163 yuan/ton compared with the beginning of January. After mid - March, due to multiple negative factors, the futures and spot prices of corn fell back [5]. - The 5 - month contract of corn oscillated repeatedly at the 2300 - yuan integer mark, and the market was worried about the lack of upward space in the future. Pay attention to the price performance of the 5 - month corn futures price at the previous support level of 2260 [6]. - The supply of new - season corn is expected to increase, and the inventory in the quarterly report at the end of March decreased by 2.4% compared with the same period. The ratio of US soybeans to corn is at a low level, which is conducive to the expansion of corn planting area [15][29][39]. - Affected by policies and other factors, the import of corn and its substitutes decreased in 2025, which increased the consumption of domestic corn. In the second quarter, the problem of limited supply of imported corn and substitutes will still appear periodically [52]. - In early April, the average price of wheat in the main producing areas decreased. The price of wheat followed the rise of corn in March and continued to oscillate weakly in April. The supply of wheat was relatively abundant, and the downstream demand was weak [55]. - In mid - April, the operating rate of the corn starch industry decreased, and the processing in Shandong was in a state of loss. The contradiction in the starch market was prominent, and the support from the demand side was insufficient [56]. Third Part: Analysis of Factors Affecting the Soybean Meal Market - The global oilseed and fat trade pattern has changed. Brazil supplies soybeans to China, the EU, etc., the US supplies soybeans to other regions, and Canadian rapeseed competes for the US soybean market [105]. - China's pig industry has strong demand for replenishment, which increases the demand for feed. The price is strong in stages, and the supply pressure is postponed [112]. - From January to February 2025, the feed output increased year - on - year, and the consumption of soybean meal also increased [116]. - The inventory of soybeans in China showed an inflection point in April, but the soybean procurement of oil mills from June to September was slow [119]. - The spot basis of soybean meal weakened, and the inter - month spread changed from backwardation to contango [121]. Fourth Part: Outlook for the Future Market - In the second quarter, pay attention to tariffs and weather for the US corn market. The policy support of CGC is nearing its end, and it will be tested whether downstream demand can accept high - priced raw materials [66][68]. - Russia's corn production has decreased, and the toxin content in domestic corn is high. The CBOT corn has emerged from the trough. In the future, Sino - US relations will determine the country of import and the rhythm [70]. - In the first quarter, the price of US corn rebounded to the profit range. The market expects an increase in the sown area of new - season corn, and the area will be confirmed in June [77]. - In the first quarter, the spot price of corn rebounded, and the futures price followed. The basis of the 3 - month and 5 - month contracts returned to normal. In the second quarter, the market will speculate on the sowing and cost changes of new - season grain [84]. - In 2024, the cost of corn planting decreased by 15 - 20%. The market expects the cost of corn planting in the new year to decrease by 100 - 150 yuan/ton [90]. - The by - products of starch rose and fell alternately. In 2024, the spread between starch and corn mainly widened. In 2025, pay attention to starch exports and the substitution of tapioca starch [97]. - In 2024, the supply of corn exceeded demand, and the price declined all the way.
