The CSI 300 Index fluctuated widely, closing at 4463.78, up 77.66 [1]. - **Coke and Coking Coal**: On August 28, the coke weighted index weakened, closing at 1672.5, down 8.0. The coking coal weighted index fluctuated narrowly, closing at 1170.9 yuan, up 11.2 [1][2]. - **Zhengzhou Sugar**: The US sugar fluctuated narrowly on Wednesday. Affected by weak demand and lower spot quotes, the long positions of the Zhengzhou Sugar 2601 contract fell on Thursday. At night, it continued to decline slightly under short - selling pressure. As of August 27, the number of ships waiting to load sugar at Brazilian ports was 72, up from 70 the previous week, and the quantity of sugar waiting to be loaded was 2.7221 million tons, down from 2.9169 million tons the previous week [3]. - **Rubber**: The Thai Meteorological Department warned of heavy rain from August 28 to September 3, which may cause floods. Toyota's auto production and sales in July reached a record high. Affected by these factors, Southeast Asian spot quotes rose, and Shanghai rubber rose on Thursday but fell slightly at night under short - selling pressure. From January to July 2025, Vietnam's total exports of natural rubber and mixed rubber were 889,000 tons, a year - on - year decrease of 0.8% [4]. - **Soybean Meal**: Internationally, on August 28, CBOT soybean futures fluctuated. The US Department of Agriculture reported that in the week ending August 21, the net export sales of US soybeans in the current market year decreased by 189,200 tons, in line with market expectations, and the net export sales of next - year soybeans were 1.3726 million tons, higher than expected. The US soybeans are growing well, and the probability of weather speculation this year is decreasing. Domestically, on August 28, soybean meal futures weakened. The M2601 main contract closed at 3039 yuan/ton, down 0.2%. Currently, soybean crushing volume is high, and the inventory is increasing. The price of soybean meal is expected to continue to fluctuate weakly [4][5]. - **Live Pigs**: On August 28, live pig futures prices weakened. The LH2511 main contract closed at 13,590 yuan/ton, down 1.13%. There are signs of slow recovery in demand during the back - to - school season, but the support for pig prices is limited. The supply of suitable - weight pigs is sufficient, and the supply pressure in the fourth quarter of this year and the first quarter of next year remains high [5]. - **Palm Oil**: On August 28, palm oil futures declined, breaking through the previous high - level range. The main contract P2601 closed at 9414, down 0.91%.

LME copper inventory has accumulated slightly, and domestic refined copper social inventory is still at a low level. The spot processing fee for copper concentrate remains low, and the smelting end is performing well. The demand side is weak, and Shanghai copper continues to fluctuate within a range [6]. - **Logs**: On August 28, the 2511 contract of logs opened at 815, with a low of 810, a high of 825, and closed at 821.5, with an increase of 363 lots in positions. The 60 - day moving average provides support at 810 and resistance at 825. The spot prices in Shandong and Jiangsu remained unchanged. The increase in foreign quotes drove up the domestic futures price. The supply - demand relationship has no major contradictions, and the spot trading is weak [7]. - **Cotton**: On Thursday night, the main contract of Zhengzhou cotton closed at 14,270 yuan/ton. On August 29, the minimum basis quote at the Xinjiang designated delivery (supervision) warehouse of the National Cotton Trading Market was 900 yuan/ton, and the cotton inventory decreased by 139 lots compared with the previous trading day [7]. - **Steel**: On August 28, rb2601 closed at 3205 yuan/ton, and hc2601 closed at 3372 yuan/ton. From late August to early September, northern steel mills and coke enterprises will implement temporary environmental protection restrictions, and demand is expected to improve in September. Steel prices are expected to fluctuate in the short term, with limited upside and downside [7]. - **Alumina**: On August 28, ao2601 closed at 3063 yuan/ton. Alumina inventory has been steadily accumulating, with a weekly accumulation of 5 - 7 million tons for four consecutive weeks. The supply and demand of the alumina market are both at a high level and relatively stable. Without a significant reduction in supply, the oversupply situation will continue [9]. - **Shanghai Aluminum**: On August 28, al2510 closed at 20,750 yuan/ton. The supply is stable, the inventory is moderate, and the cost support is strong. The demand is stable, and the price is expected to remain stable [9]. Influencing Factors - **Coke**: Spot prices have started the eighth round of increases, and some northern coke enterprises have started production restrictions. However, due to the rapid decline in blast furnace profits, it is difficult for coke prices to continue to rise. The supply - demand gap still exists [3]. - **Coking Coal**: A coal mine accident in Fujian has raised concerns about increased safety supervision. Mine supply has recovered this week, and the operating rate of coal washing plants has declined slightly. Upstream inventory has increased again, and downstream inventory has decreased [3].

Variety Viewpoints Stock Index Futures - On August 21, A-share market's three major indexes showed mixed performance, with the Shanghai Composite Index hitting a ten-year high, closing up 0.13% at 3771.10 points; the Shenzhen Component Index down 0.06% at 11919.76 points; and the ChiNext Index down 0.47% at 2595.47 points. The trading volume of the two markets reached 2424.1 billion yuan, a slight increase of 1.58 billion yuan from the previous day [1] - The CSI 300 index had a strong oscillation on August 21, closing at 4288.07, up 16.68 compared to the previous day [2] Coke and Coking Coal - On August 21, the weighted index of coke remained weak, closing at 1661.0, down 14.7 compared to the previous day [3] - On August 21, the weighted index of coking coal was weak, closing at 1140.6 yuan, down 14.0 compared to the previous day [4] - For coke, due to an approaching major event, there are expectations of production limitations at coking plants in East China. After the seventh price increase, coking profits have improved slightly, and daily coking production has increased slightly. Overall coke inventory is decreasing, and traders' purchasing willingness is strong. The supply of carbon elements is abundant, and downstream molten iron production remains at a high level during the off - season [5] - For coking coal, the output of coking coal mines has decreased. The spot auction market has performed well, with prices mostly rising, and terminal inventory remaining flat. The total coking coal inventory has decreased month - on - month, and the decline in production - end inventory has narrowed. It is likely to continue destocking in the short term [5] Zhengzhou Sugar - Recently, the increase in refining profit has boosted the demand for raw sugar. The market expects that China's strong import pace in July may continue for at least the next few months. Supported by these factors, US sugar oscillated higher on Wednesday. Due to the start of stockpiling for the National Day and Mid - Autumn Festival, the spot price has been firm recently. Affected by the rise in US sugar and the increase in spot price, the Zhengzhou Sugar 2601 contract oscillated upward on Thursday. However, due to the large short - term increase, it oscillated and adjusted slightly lower at night. In July 2025, China's imports of syrup and premixes totaled 159,700 tons, a year - on - year decrease of 68,600 tons, but a month - on - month increase, hitting a new high for the year [5] Rubber - Thailand's meteorological agency warned of possible floods from August 21 to 26. Supported by concerns about bad weather in major rubber - producing areas, Shanghai rubber oscillated slightly higher on Thursday. At night, it fluctuated slightly. According to LMC Automotive, in July 2025, the seasonally adjusted annualized sales volume of global light vehicles rose to 94 million vehicles per year. Year - on - year, the global market sales volume increased by more than 6% to 7.46 million vehicles [6] Soybean Meal - In the international market on August 21, CBOT soybean futures rose sharply due to short - covering and bargain - hunting. The November contract of US soybeans closed at 1055 cents per bushel. During the Pro Farmer Midwest crop tour on Wednesday, the inspection team found that the soybean outlook in western Iowa was much better than average. Brazil's National Association of Grain Exporters (Anec) said that Brazil's soybean exports in August are expected to be 8.9 million tons, higher than the previous week's forecast of 8.8 million tons [6] - In the domestic market on August 21, the M2601 main contract closed at 3113 yuan per ton, a decrease of 1.49%. Chinese importers have not purchased new - crop US soybeans. All the purchased soybean orders for the fourth quarter are from South America. The increase in Brazilian soybean costs and the non - purchase of new - crop US soybeans have raised concerns about a tightening of later - stage soybean meal supply, which has significantly supported forward prices. However, currently, the supply of imported soybeans is sufficient, oil refineries' operating rates are high, which has promoted the recovery of soybean meal inventory. The abundant supply has put pressure on soybean meal prices. Future focus should be on the weather in the producing areas and soybean import situation [8] Live Pigs - On August 21, live pig futures prices oscillated weakly. The LH2511 main contract closed at 13765 yuan per ton, a decrease of 0.07%. Currently, it is the off - season for pork consumption. High - temperature weather has led to weak terminal demand. The order volume of major pig enterprises is low, and the operating level remains low, which has put some pressure on prices. In August, production capacity is being realized intensively, the supply of suitable - weight pigs has increased, and the monthly slaughter plans of group pig enterprises have increased. Currently, the live pig market is in a situation of abundant supply and demand. Future attention should be paid to policy regulation trends, pig slaughter rhythm, and weight changes [8] Palm Oil - On August 21, palm oil futures continued to oscillate slightly at a high level. The main contract P2601 closed with a small upper - shadowed negative line, with a high of 9636, a low of 9480, and a closing price of 9500, down 0.57% from the previous day. According to foreign media reports, data from the Indonesian Palm Oil Association (GAPKI) on Thursday showed that despite increased production and accelerated exports, Indonesia's palm oil inventory at the end of June decreased by 13% month - on - month to 2.53 million tons. As the world's largest palm oil producer and exporter, Indonesia's palm oil exports in June reached 3.61 million tons, a month - on - month surge of 35.4% driven by the soaring demand from major buyers such as China and India. In June, the production of crude palm oil increased by 15.8% month - on - month to 4.82 million tons; the total production (including palm kernel oil) in the first half of this year reached 27.89 million tons, a year - on - year increase of 6.5% [9] Shanghai Copper - The main contract of Shanghai copper showed a narrow - range oscillation pattern. Fundamentally, the arrival of domestic refineries has increased, and the supply pattern of electrolytic copper has turned abundant. However, as the seasonal off - season ends, downstream demand is expected to pick up. At the macro level, the expectation of a Fed rate hike in September has decreased, which has supported copper prices. In the short term, Shanghai copper may continue to oscillate in the range of 78,000 - 79,500 yuan. If it breaks through the key resistance level of 79,000 yuan, it may open up an upward space. In the spot market, domestic copper is still being warehoused, and affected by imported low - price goods, the spot premium of Shanghai copper may further decline. However, downstream purchasing sentiment may be strong, and the decline is expected to be limited [10] Cotton - On Thursday night, the main contract of Zhengzhou cotton closed at 14045 yuan per ton. According to the China Cotton Information Network on August 22, at the Xinjiang designated delivery (supervision) warehouses of the National Cotton Exchange, the lowest basis quotation was 1070 yuan per ton, and the cotton inventory decreased by 120 lots compared to the previous day. According to the US weather forecast, the drought area in the US will increase from August to October [10] Iron Ore - On August 21, the 2601 main contract of iron ore oscillated higher, with a gain of 0.98% and a closing price of 772.5 yuan. The global shipment and arrival volume of iron ore have both increased this period, and port inventory has continued to rise. Molten iron production has increased slightly. However, as environmental protection policies in the north become stricter before the September military parade, there are expectations of a decrease in molten iron production. In the short term, iron ore prices are in an oscillating trend [10] Asphalt - On August 21, the 2510 main contract of asphalt oscillated higher, with a gain of 0.38% and a closing price of 3465 yuan. The capacity utilization rate of asphalt has decreased month - on - month this period. Terminal demand is limited by rainfall and funds, and there has been no significant improvement in demand. Without obvious one - way driving factors, asphalt prices will oscillate in the short term [11] Logs - On August 20, the 25091 contract opened at 804, had a low of 803, a high of 812, and closed at 804.5, with a decrease of 825 lots in positions. Attention should be paid to the support at 800 and the resistance at 820 [11] - On August 21, the spot price of 3.9 - meter medium - grade A radiata pine logs in Shandong was 750 yuan per cubic meter, unchanged from the previous day; the spot price of 4 - meter medium - grade A radiata pine logs in Jiangsu was 780 yuan per cubic meter, also unchanged from the previous day. Customs data on the 18th showed that in July, log imports were 2.5 million cubic meters, a year - on - year decrease of 17.7%. The cumulative imports from January to July decreased by 11.7% year - on - year. The increase in overseas prices has driven up the domestic futures price. There is no major contradiction in the supply - demand relationship, with a game between strong expectations and weak reality. Spot trading is weak. Attention should be paid to the spot price during the peak season, import data, inventory changes, and the support of macro - expectations and market sentiment on prices [13] Steel - On August 21, rb2510 closed at 3121 yuan per ton, and hc2510 closed at 3375 yuan per ton. As steel prices have fallen for several consecutive days, the purchasing enthusiasm of downstream buyers has increased slightly, and the sales of low - price resources have improved. At the same time, most steel mills in Tangshan have maintenance plans, and it is expected that the supply - demand pressure will ease at the end of August and early September. The market should not be overly bearish. In the short term, steel prices will have limited fluctuations and may oscillate in a narrow range [13] Alumina - On August 21, ao2601 closed at 3124 yuan per ton. Fundamentally, the positive factors in the alumina market have faded. The 10.7% month - on - month increase in bauxite imports in July shows that the supply of imported ore has not been significantly affected by the rainy season. Domestic operating capacity remains high, and the import window opens intermittently. The pattern of oversupply will continue in the second half of the year. The alumina warehouse receipt inventory on the Shanghai Futures Exchange has continuously increased to 72,000 tons, alleviating liquidity concerns and dampening bullish sentiment. Alumina is in an oscillating adjustment [14] Shanghai Aluminum - On August 21, al2510 closed at 20590 yuan per ton. In terms of inventory, domestic electrolytic aluminum inventory is 571,000 tons, an increase of 23,000 tons from last week, and it has been accumulating for five consecutive weeks, but the support from low inventory still exists. In the short term, the main contract of Shanghai aluminum has changed to al2510. It is restricted by demand above and supported by macro - stimulus and low inventory below. It will continue to oscillate. If the electrolytic aluminum inventory accumulates rapidly, aluminum prices may be under pressure [14]

Core Viewpoints - On August 19, A - share major indices oscillated, with the Shanghai Composite Index down 0.02%, Shenzhen Component Index down 0.12%, and ChiNext Index down 0.17%. The trading volume of the two markets shrank by 175.8 billion yuan compared to the previous day. Different futures varieties showed diverse trends, affected by various factors such as supply - demand, policies, and international events [1]. 3. Summary by Variety **Stock Index Futures** - On August 19, the A - share major indices oscillated. The Shanghai Composite Index closed at 3727.29, down 0.02%; the Shenzhen Component Index closed at 11821.63, down 0.12%; the ChiNext Index closed at 2601.74, down 0.17%. The trading volume of the two markets was 2588.4 billion yuan, a decrease of 175.8 billion yuan from the previous day. The CSI 300 index adjusted and consolidated, closing at 4223.37, down 16.04 [1]. **Coke and Coking Coal** - Coke: Due to an approaching major event, there is a renewed expectation of production restrictions in coking plants in East China. After the seventh price increase, coking profits have improved, and daily coking production has slightly increased. The overall coke inventory is decreasing, and traders' purchasing willingness is strong. The carbon element supply is abundant, and the high - level of downstream hot metal during the off - season, along with the market sentiment on coal over - production inspection, drives the coke price. The coke futures price is affected by the "anti - involution" policy expectation [2]. - Coking Coal: The output of coking coal mines has decreased. The spot auction market is doing well, with rising transaction prices. The terminal inventory remains flat. The total coking coal inventory has decreased month - on - month, and the decline in production - end inventory has narrowed. It is likely to continue destocking in the short term [2]. **Zhengzhou Sugar (Zheng Sugar)** - Brazil exported 1,883,277.33 tons of sugar in the first two weeks of August, with an average daily export volume of 171,207.03 tons, a 4% decrease compared to the average daily export volume in August last year. Affected by the concern of decreased demand, US sugar oscillated and declined on Monday. Due to the decline of US sugar and the relatively large import volume in July, the short - sellers pressured the Zheng Sugar 2601 contract, which oscillated downward on Tuesday and at night [2]. **Rubber (Hu Jiao)** - Thailand's meteorological agency warned of possible floods from August 21 - 25, and the Southeast Asian spot quotation is firm. The decline in oil prices and the news of tri - lateral talks between Russia, Ukraine, and the US may lead to the lifting of sanctions on Russian crude oil. Affected by these factors, Hu Jiao oscillated narrowly and closed slightly higher on Tuesday. Due to the significant increase in inventory in Qingdao Free Trade Zone last week, Hu Jiao oscillated lower at night. As of August 17, the total inventory of natural rubber in Qingdao's bonded and general trade areas was 616,700 tons, a decrease of 3100 tons (0.50%) from the previous period. The bonded area inventory increased by 2.12% to 76,900 tons, and the general trade inventory decreased by 0.87% to 539,800 tons [3][4]. **Palm Oil** - On August 19, palm oil reached a new high, but in the afternoon, long - position holders took profits, causing the price to give back some gains at the end of the session. The main contract P2601 closed with a small doji star with an upper shadow, closing at 9640, up 0.58% from the previous day. From August 1 - 15, 2025, Malaysia's palm oil yield per unit decreased by 1.78% month - on - month, the oil extraction rate increased by 0.51% month - on - month, and the output increased by 0.88% month - on - month [4]. **Soybean Meal** - Internationally, on August 19, CBOT soybean futures oscillated and closed lower. The US Department of Agriculture maintained the soybean crop condition rating at 68% in the weekly report, the same as last year and the highest since 2020. Domestically, on August 19, the M2601 main contract closed at 3163 yuan/ton, up 0.19%. Currently, the supply of imported soybeans is abundant, oil mills are operating at a high capacity, and the soybean meal inventory is high. Although the Brazilian premium has slightly declined, the high price of US soybeans keeps the domestic import cost high. The expected tightening of supply in the fourth quarter provides support for the soybean meal market. Future focus should be on the weather in the producing areas and soybean imports [5]. **Live Hogs** - On August 19, the live hog futures price oscillated. The LH2511 main contract closed at 13900 yuan/ton, up 0.58%. Currently, it is the off - season for pork consumption, and the high - temperature weather has led to weak terminal demand. The order volume of major pig - raising enterprises is low, and the operation level is low, suppressing the price. In August, the production capacity is being realized, the supply of suitable - weight pigs has increased, and the planned slaughter of group pig - raising enterprises has increased month - on - month. Although the number of secondary fattening has increased, the overall scale is limited. The live hog market is currently in a state of loose supply and demand. Future attention should be paid to policy regulation, hog slaughter rhythm, and weight changes [6]. **Iron Ore** - On August 19, the iron ore 2601 main contract oscillated and closed lower, down 0.64%, closing at 771 yuan. The global iron ore shipment and arrival volume have increased, and the port inventory has continued to rise. The hot metal output has slightly increased, but with the tightening of environmental protection policies in the north before the September parade, there is an expectation of hot metal production reduction. In the short term, the iron ore price will oscillate [6]. **Asphalt** - On August 19, the asphalt 2510 main contract oscillated and closed lower, down 0.6%, closing at 3453 yuan. Last week, the asphalt production capacity utilization rate increased month - on - month, the shipment volume continued to decline, and the demand side has not improved significantly. The fundamentals lack obvious drivers, and the asphalt price will oscillate in the short term [6]. **Log** - On August 19, the 25091 log contract opened at 809.5, with a low of 807, a high of 816.5, and closed at 810.5, with a daily reduction of 1113 lots. Attention should be paid to the support at 800 and the resistance at 820. The spot prices of medium - grade A radiata pine logs in Shandong and Jiangsu remained unchanged from the previous day. Customs data on the 18th showed that the log import volume in July was 2.5 million cubic meters, a 17.7% year - on - year decrease, and the cumulative import volume from January - July decreased by 11.7% year - on - year. The increase in the overseas quotation has driven up the domestic futures price. There is no major contradiction in the supply - demand relationship, and there is a game between strong expectations and weak reality. The spot trading is weak. Attention should be paid to the spot price during the peak season, import data, inventory changes, and the support of macro - expectations and market sentiment on the price [7]. **Cotton** - On Tuesday night, the main contract of Zhengzhou cotton closed at 13955 yuan/ton. On August 20, the minimum basis quotation at the Xinjiang designated delivery (supervision) warehouse of the National Cotton Trading Market was 1070 yuan/ton, and the cotton inventory decreased by 166 lots from the previous day. India announced on August 18 that it will fully exempt cotton import tariffs and agricultural surcharges from August 19 to September 30 [7][8]. **Shanghai Copper (Hu Tong)** - Shanghai copper oscillated with a slight decline. On the one hand, the concentrated arrival of imported copper in Shanghai has increased the inventory, and there is still pressure on subsequent shipments, which may lead to a decline in the spot premium and affect the futures price. On the other hand, it is the off - season for copper consumption, and the demand is mainly supported by power grid orders, so the consumption side cannot strongly boost the price. In the long term, the new - energy demand provides some support for the price, and the expected increase in copper mine production but the decline in the global refined copper supply growth rate in 2025 will also affect the price [8]. **Steel** - On August 19, the rb2510 contract closed at 3126 yuan/ton, and the hc2510 contract closed at 3416 yuan/ton. The demand for steel in the off - season continues to decline, and the supply - demand pressure has increased. Considering the planned production restrictions of Tangshan steel mills at the end of August and early September, the market bearish sentiment is not strong. The raw materials have shown different trends, with coke starting the seventh price increase and Shagang reducing the scrap steel purchase price by 30 yuan/ton. In the short term, the steel price may oscillate weakly [8]. **Alumina** - On August 19, the ao2601 contract closed at 3120 yuan/ton. Recently, the production reduction of some alumina plants has slightly decreased the operating capacity and output. However, the raw material inventory of aluminum plants has reached a historical high, and the提货 willingness has weakened, leading to a slowdown in demand and an increase in inventory. With the expected release of new production capacity, there is still pressure on supply surplus. Attention should be paid to the potential impact of production reduction policies around Beijing - Tianjin - Hebei on alumina production. Currently, the market is mixed, with the rapid increase in warehouse receipt inventory competing with structural shortages, and the alumina price will continue to oscillate [9]. **Shanghai Aluminum (Hu Lu)** - On August 19, the al2510 contract closed at 20545 yuan/ton. The aluminum price maintains a weak range structure, oscillating with low trading volume. The center of the price range is lower, and it oscillates narrowly. Downstream buyers are mostly waiting and watching. The high inventory of aluminum ingots puts pressure on the spot price. Although there is an expectation of stockpiling before the peak season, the high inventory and weak aluminum price have limited support for the premium [9].

Palm Oil - The significant increase in Malaysian palm oil exports from August 1 - 10 compared with the same period last month supported the upward movement of palm oil prices [6]. Soybean Meal - The US Department of Agriculture's adjustment of soybean sown area and yield estimates affected the supply expectation. The rise in US soybean prices increased the cost of imported soybeans, but the high domestic inventory limited the upward space of soybean meal prices [7]. Live Pigs - The current low - season consumption and the expected increase in supply from group farms and the release of previously - pressed large pigs put pressure on live pig prices [8]. Copper - The supply of domestic copper increased, but the high cost of holders limited the decline of spot premiums. The approaching "Golden September and Silver October" might support copper prices [8]. Iron Ore - The decrease in global iron ore shipments and arrivals tightened the supply, while the high iron - water production and high profitability of steel mills supported the demand, resulting in a short - term oscillatory trend [12]. Asphalt - The decrease in asphalt production capacity utilization and shipments, along with weak demand but low inventory, led to a short - term oscillatory trend [12]. Steel - The slow resumption of domestic coal mines and weakening downstream procurement enthusiasm affected the coking coal market. The short - term steel price increase slowed down due to limited improvement in terminal demand [12]. Alumina - The short - term supply of alumina was affected by various factors, but the medium - term supply would increase due to profit - driven capacity recovery [13]. Aluminum - The continuous inventory accumulation of aluminum was limited, and the approaching peak season and expected Fed rate cut in September might drive up aluminum prices [13].
