Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core View of the Report - The short - term lithium carbonate futures may continue the volatile and weak pattern, with market focus on the开工 dynamics of lithium mines and salt plants in Jiangxi. The futures rebound space is limited by the rapid convergence of the basis. Potential variables include whether CATL's suspension triggers other salt plants to passively support prices and the marginal support of nickel - cobalt salt price increases on ternary material costs [4] Group 3: Summary by Relevant Catalogs 1. Daily Market Summary - **Lithium Carbonate Futures Market Data Changes** - On September 4, the main lithium carbonate contract closed at 73,420 yuan/ton, up 2.14% from the previous trading day. The basis narrowed significantly from 3,620 yuan/ton on September 3 to 1,280 yuan/ton. The main contract's open interest increased to 353,600 lots, and trading volume soared to 712,200 lots, indicating increased market activity [2] 2. Industrial Chain Supply - Demand and Inventory Changes - **Supply Side** - The proportion of lithium carbonate output from the spodumene smelting end has exceeded 60%, while that of lepidolite has dropped to 15%. Although the lithium carbonate capacity utilization rate remained stable at 66.41% in September, the suspension of CATL's Yichun mining area may intensify local supply disturbances, and the resumption rhythm of salt plants needs attention [3] - **Demand Side** - The downstream shows the characteristic of "weak peak season". In August, the retail penetration rate of new - energy passenger vehicles reached 55.3%, but the cost pressure of power batteries was transmitted to the mid - and upstream. The transaction price of lithium iron phosphate battery cells fell to 0.324 yuan/Wh, and the price of ternary materials also declined continuously. The demand for electrolyte and anode materials was boosted by the "Golden September and Silver October" stocking, but over - capacity restricted the price increase space [3] - **Inventory and Warehouse Receipts** - The total lithium carbonate inventory decreased to 141,100 tons, but the absolute value was still at a high level, and the de - stocking speed was slow [3] 3. Market Price Monitoring - On September 4, the main lithium carbonate contract closed at 73,420 yuan/ton, up 2.14% from the previous day. The basis narrowed from 3,620 yuan/ton on September 3 to 1,280 yuan/ton. The battery - grade lithium carbonate market price was 74,700 yuan/ton, down 1.06% from the previous day. The price of power - type ternary materials decreased by 0.08% to 118,700 yuan/ton, and the price of power - type lithium iron phosphate decreased by 0.63% to 33,995 yuan/ton. The lithium carbonate capacity utilization rate remained at 66.41%, and the inventory decreased by 0.29% to 141,136 tons [6] 4. Industrial Dynamics and Interpretation - **Spot Market Quotes** - On September 4, the SMM battery - grade lithium carbonate index price was 74,869 yuan/ton, down 886 yuan/ton from the previous working day. The battery - grade lithium carbonate was priced at 73,400 - 76,600 yuan/ton, with an average price of 75,000 yuan/ton, down 900 yuan/ton. The industrial - grade lithium carbonate was priced at 72,000 - 73,400 yuan/ton, with an average price of 72,700 yuan/ton, down 900 yuan/ton. In September, the market shows a situation of both supply and demand increasing, with demand growing faster, and there will be a stage of tight supply [7] - **Downstream Consumption** - According to preliminary statistics from the Passenger Car Association on September 3, from August 1 - 31, the retail sales of new - energy passenger vehicles in the national market were 1.079 million, a year - on - year increase of 5% and a month - on - month increase of 9%. The retail penetration rate of the new - energy market was 55.3%, and the cumulative retail sales this year were 7.535 million, a year - on - year increase of 25%. The wholesale of new - energy passenger vehicles by national manufacturers was 1.292 million, a year - on - year increase of 23% and a month - on - month increase of 9%. The wholesale penetration rate of new - energy manufacturers was 53.6%, and the cumulative wholesale this year was 8.926 million, a year - on - year increase of 33% [8] - **Industry News** - From August 21 - 28, the spot price of cobalt intermediates continued to rise. Affected by the Congo (Kinshasa) extension policy, China's cobalt intermediates will face raw material shortages in the future, and prices have upward momentum. Since August 10, CATL's Yichun mining area in Jiangxi has been shut down, and the "butterfly effect" has spread throughout the industry chain [9][10][11]

Report Industry Investment Rating No information provided on the report industry investment rating. Core View of the Report Short - term crude oil prices may maintain a weak oscillation, with SC performing weaker than the external market. The undecided OPEC+ production increase decision, anti - seasonal accumulation of US commercial crude oil inventories, and weakening distillate oil demand weaken the fundamental support. However, the faster - than - expected pace of gasoline destocking provides some support. Geopolitical factors bring regional disturbances but have limited impact on global supply and demand. Technically, the SC contract has broken below the short - term moving average and the basis has weakened, with a risk of further decline, but the sideways movement of WTI and Brent may limit the decline. In the medium term, attention should be paid to the OPEC+ policy direction and the seasonal demand switch in the US [5]. Summary by Relevant Catalogs 1. Daily Market Summary - **Crude Oil Futures Market Data Changes**: On September 4, the price of the SC main contract dropped to 481 yuan/barrel (-2.47%), while WTI and Brent prices remained at 63.77 dollars/barrel and 67.39 dollars/barrel, unchanged from the previous day. The SC - Brent spread narrowed significantly from 1.62 dollars/barrel to - 0.02 dollars/barrel, and the SC - WTI spread also narrowed by 1.64 dollars to 3.6 dollars/barrel. The SC continuous - consecutive three spread fell from 1.2 yuan/barrel to 0.5 yuan/barrel, indicating weakened support for near - term contracts [1]. - **Supply - side**: Iraq's oil exports in August remained at 3.38 million barrels per day without significant fluctuations. Indonesia's gasoline imports decreased by 22% year - on - year due to import quota restrictions, and Shell suspended supplies at some gas stations, increasing the risk of regional supply shortages. The uncertainty of the OPEC+ production increase decision is a core disturbing factor, and if production increase continues, it may further pressure oil prices [2]. - **Demand - side**: US refinery demand is divided. EIA data shows that the derived demand for crude oil production decreased slightly from 20.015 million barrels per day to 19.82 million barrels per day, but gasoline inventories decreased by 3.795 million barrels, the largest decline in nearly 5 months and the seventh consecutive week of decline, reflecting the remaining consumption resilience before the end of the travel peak season. Distillate fuel demand declined significantly from 5.6131 million barrels per day to 5.1089 million barrels per day, suggesting a weakening of industrial and logistics demand [3]. - **Inventory - side**: US commercial crude oil inventories unexpectedly increased by 2.415 million barrels (expected - 2.031 million barrels), offsetting the previous week's destocking, and inventories at Cushing and strategic petroleum reserves also increased. However, the larger - than - expected decline in gasoline inventories offset some of the negative factors, indicating the continuation of structural destocking of terminal oil products. Singapore's fuel oil inventories increased significantly, and the spot discount remained, pressuring the heavy distillate market [4]. 2. Industrial Chain Price Monitoring - **Crude Oil**: The prices of SC, WTI, and Brent futures all declined on September 4 compared to the previous day. Among them, SC decreased by 12.2 yuan/barrel (-2.47%), WTI decreased by 0.43 dollars/barrel (-0.67%), and Brent decreased by 0.51 dollars/barrel (-0.76%). Most spot prices also declined, and spreads such as SC - Brent, SC - WTI, and Brent - WTI all narrowed. US commercial crude oil inventories, Cushing inventories, and strategic petroleum reserve inventories all increased, while the US refinery weekly operating rate and crude oil processing volume decreased slightly [7]. - **Fuel Oil**: The futures prices of FU, LU, NYMEX fuel oil, etc. all declined on September 4 compared to the previous day. Singapore's fuel oil inventories increased by 1.689 million tons, a 7.33% increase. Some US distillate inventories increased, while others decreased [8]. 3. Industrial Dynamics and Interpretation - **Supply**: From August 22 - 29, US EIA crude oil imports increased, and Iraqi oil exports in August averaged 3.38 million barrels per day. In Indonesia, due to import restrictions, some Shell gas stations suspended fuel supplies, and gasoline imports decreased by 22% year - on - year as of the end of August [9][10]. - **Demand**: From August 22 - 29, US EIA distillate fuel derived demand and crude oil derived demand decreased, and gasoline production also decreased [11]. - **Inventory**: From August 22 - 29, US EIA strategic petroleum reserve inventories reached the highest level since the week of October 14, 2022, and gasoline inventories had the largest decline since the week of April 25, 2025, with a seventh consecutive week of decline. Singapore's fuel oil inventories increased significantly, and some energy - related futures warehouse receipts decreased [12][14]. - **Market Information**: The uncertainty of OPEC+ production increase is high, which may affect crude oil prices. Qatar raised the official selling prices of its crude oil. US energy minister said that oil and gasoline prices are at a healthy level. Indonesian state - owned oil company is seeking a $2.5 billion short - term loan [16]. 4. Industrial Chain Data Charts The report provides multiple data charts, including the prices and spreads of WTI and Brent first - line contracts, US crude oil weekly production, OPEC crude oil production, etc., with data sources from WIND, EIA, etc. [17][19][21]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - China's "anti-involution" policies since July 2025 aim to address cut - throat competition, guide industrial upgrading, and promote high - quality development, impacting multiple futures market sectors [2]. - The "anti-involution" policy in the refining and chemical industry will have a structural and gradual impact on crude oil supply and demand, accelerating the clearance of inefficient capacity in the short term and promoting high - quality development and product structure optimization in the long term [10]. Summary by Related Catalogs Impact on Different Market Sectors - **New Energy Sector**: The policy significantly boosted the new energy sector, with polysilicon futures leading the rally, rising 64.42% from July 1 to September 1, and lithium carbonate showing a rise of 20.93% during the same period [3]. - **Black - Series Varieties**: The impact on black - series varieties was differentiated. Coking coal rose 30.51%, coke 11.70%, and rebar only 3.28% from July 1 to September 1 [3]. - **Chemical Industry**: The "anti - involution" policy in the chemical industry is deepening from system construction to special rectification. Glass rose 6.76%, while PVC was almost flat [4]. Current Situation of the Refining and Chemical Industry - The refining and chemical industry faces severe over - capacity, with a capacity utilization rate of less than 80% and an over - capacity of about 60 million tons. The industry's operating income profit margin has been declining [5]. - Refinery operating rates are low, indicating weak demand. In March 2025, the overall capacity utilization rate was only 70.3%, and Shandong's local refinery operating rate hit a 23 - month low in July [6]. - China's crude oil processing volume is on a downward trend, with different scenarios forecasted by Zhuochuang Information in 2025 [6]. Content of the Upcoming Reform Plan - The plan includes shutting down small refineries with an annual capacity of less than 2 million tons, which could potentially reduce crude oil processing demand by about 30 million tons/year (about 603,000 barrels/day) [5]. - It aims to upgrade about 40% of petrochemical facilities that have been in use for over 20 years through multi - dimensional evaluations [7]. - It encourages the industry to shift from producing bulk chemicals to special fine chemicals for high - tech fields [7]. Long - term Impact on the Refining and Chemical Industry - The policy will drive the industry towards large - scale, integration, and high - end transformation, increasing the proportion of high - value - added chemical products and changing the quality and structure of crude oil demand [7]. - The "oil - reduction and chemical - increase" trend may lead to a shortage of naphtha supply, driving the popularity of alternative raw materials and increasing import dependence on high - value - added chemicals [8]. Impact on the Global Crude Oil Market - China's adjustment of refining policies may slow down or even decrease its crude oil import growth rate, leading to an adjustment in international crude oil trade flows [9]. - The policy may reduce the demand for high - sulfur heavy crude oil and benefit the low - sulfur light crude oil market [9]. - Although China's potential demand reduction will intensify the global supply - demand surplus, the final trend of global oil prices depends on OPEC+ policies, the global macro - economy, and geopolitical events [9].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - PX and PTA absolute prices have fallen from their highs. With the cost - side oil price stabilizing and the positive news exhausted, the market focus returns to fundamentals, and the downstream demand becomes the main contradiction. The demand recovery is hard to boost raw material prices [2]. - The absolute price of MEG has also fallen from its high. The MEG port inventory has been continuously declining significantly, and the supply - side increase space is limited, so there is still support at the bottom [2]. - PF and PR mainly follow cost changes. The short - fiber and bottle - chip prices fluctuate with costs, and attention should be paid to the actual performance of terminal demand at the end of the peak season [3]. Summaries According to Relevant Catalogs 1. Market Review - PX: Valuation returns to fundamentals as the hype on the news side is over, and there are doubts about the sustainability of demand recovery [5][21]. - PTA: The market circulation is abundant, and there are doubts about the sustainability of demand recovery [5][34]. - MEG: Domestic production continues to rise, and there may be support at the valuation bottom under low inventory [5][43]. - PF and PR: Mainly follow cost changes, and attention should be paid to the actual performance of terminal demand at the end of the peak season [3]. 2. PX Market Analysis - **Macro - factors**: After the US Labor Day, the seasonal demand inflection point is approaching. The market generally expects OPEC+ to suspend production increases in October. Geopolitical risks are still the biggest potential positive factor in the crude - oil market. In the short - term, sanctions and inventory decline provide main support, and in the long - term, the global economic recovery rhythm should be focused on [22]. - **Cost - related**: Naphtha prices are stable, and PX - N benefits are compressed. There are differences in short - process profits, and the refined oil price difference shows an upward trend [25][28]. - **Supply - side**: The domestic PX device load is currently around 83.3%, a 1.3% month - on - month decline; the Asian device load is currently 75.6%, a 0.7% month - on - month decline [2][31][32]. 3. PTA Market Analysis - **Processing - fee aspect**: PTA processing fees are under pressure, and attention should be paid to device maintenance dynamics under low processing fees [35]. - **Supply - side**: The PTA mainland area's operating rate is around 70.4%, a 1.2% decrease. Polyester production shows no signs of increase, and the operating rates of weaving and dyeing industries have declined [38][40]. 4. MEG Market Analysis - **Price and profit**: The MEG price has fallen, and processing profits are under pressure [44]. - **Supply - side**: The domestic MEG operating rate is 75.13% (a 1.97% increase), and the synthetic - gas - to - MEG operating rate is 77.74% (a 3.51% decrease). From September 1st to September 7th, the planned arrival at the main port is about 9.8 tons [2][47]. - **Inventory**: The main - port inventory is 44.9 tons, a 5.1 - ton month - on - month decrease [48]. - **Demand - side**: The profits of polyester products have recovered at a low level, but the overall economic efficiency is still average. The sales - to - production ratio has not recovered significantly, and the transactions in the Light Textile City have increased periodically. The short - fiber inventory is relatively stable, while the inventories of other varieties are under pressure [51][54][57].

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report In the short term, the copper market may continue to fluctuate at a high level. The current price is approaching resistance, and there is a short - term need for a correction. Supply - side factors such as Chilean mine disruptions and domestic smelting maintenance expectations provide support, but the widening overseas discount and the increase in domestic social inventory suppress the upside. On the demand side, the game between the peak - season expectation and high - price suppression will dominate the price fluctuations. The increasing expectation of the Fed's interest - rate cut at the macro level may boost risk appetite, but the adjustment risk caused by the repeated policy expectations should be vigilant [5]. 3. Summary by Relevant Catalogs 3.1 Daily Market Summary 3.1.1 Main Contract and Basis On September 2, the SHFE price of the main copper futures contract rose slightly to 79,810 yuan/ton, up 50 yuan from the previous day, while the LME copper price fell slightly to 9,875 dollars/ton. The spot premium and discount showed obvious differentiation. The premium of premium copper rose slightly from 300 yuan/ton to 305 yuan/ton, while the premiums of flat - water copper and wet - process copper fell by 30 yuan and 20 yuan to 135 yuan/ton and 55 yuan/ton respectively. The LME (0 - 3) discount widened further to - 86.27 dollars/ton, indicating pressure on the overseas spot end [1]. 3.1.2 Position and Trading Volume LME inventory decreased continuously, with a 3.46% decline on September 2 to 19,501 tons, hitting a recent low. SHFE inventory decreased slightly by 100 tons to 158,775 tons, but the domestic social inventory (SMM) increased to 132,100 tons due to the replenishment of imported goods. The warehouse receipts in Guangdong decreased by 699 tons in a single day, with accelerated regional destocking. However, in the North China market, due to logistics restrictions and cautious downstream purchasing at high prices, the trading activity was low [2]. 3.1.3 Industry Chain Supply - Demand and Inventory Changes - **Supply Side**: The Mantoverde copper mine in Chile faced a short - term decline in production due to equipment failures, increasing overseas copper mine supply disturbances. Chile's copper production in July increased slightly by 0.3% year - on - year to 445,000 tons, showing that the overall supply had not significantly contracted. The domestic smelting end was about to enter the centralized maintenance period, and combined with the logistics restrictions in North China, the spot circulation volume might be tightened periodically [3]. - **Demand Side**: High - priced copper significantly suppressed consumption. In July, the air - conditioner production decreased by 14.2% month - on - month, and the white - goods production schedule in September decreased by 7.2% year - on - year, with the air - conditioner production schedule decreasing by 12% year - on - year. The terminal demand was still weak. However, under the expectation of the traditional peak seasons of "Golden September and Silver October", the demand for copper tubes and power projects might improve marginally, and the copper tube start - up rate in September was expected to rise slightly [4]. - **Inventory Side**: The domestic social inventory increased continuously to 132,100 tons, mainly due to the arrival of imported copper. However, the visible inventories of SHFE and LME continued to decline, especially the LME inventory, which decreased by 8.9% compared with August 27, indicating a marginal tightening of overseas supply - demand. Subsequently, as the import window narrowed and the peak - season demand started, the domestic inventory pressure might gradually ease [4]. 3.2 Industry Chain Price Monitoring The report provides price and inventory data for September 2, 2025, September 1, 2025, and August 27, 2025, including SMM 1 copper, spot premium and discount of different types of copper, LME (0 - 3) discount, SHFE and LME prices, and LME, SHFE, and COMEX inventories, as well as their changes and change rates [7]. 3.3 Industry Dynamics and Interpretation - On September 2, SHFE copper futures warehouse receipts decreased by 699 tons to 19,501 tons, all of which were from Guangdong warehouses. The spot premium in Guangdong remained firm when the copper price rose [8]. - On September 2, Capstone Copper's Mantoverde copper mine in Chile faced a temporary decline in production due to the failure of two ball mills within a week [8]. - On September 1, SMM's national mainstream copper inventory increased by 0.5 tons to 132,100 tons week - on - week. The inventory increase was mainly due to the continuous arrival of imported copper, and the consumption was weak due to high copper prices. In the future, SMM expected that the imported copper would continue to arrive, and the copper inventory would decrease month - on - month as the demand recovered in the "Golden September and Silver October" [8]. - On September 1, in the North China market, logistics was restricted during the Tianjin Summit, and the copper price increase suppressed downstream buying interest, resulting in low trading activity [9]. - On August 31, Chile's copper production in July increased slightly by 0.3% year - on - year to 445,214 tons [9]. 3.4 Industry Chain Data Charts The report includes charts such as China PMI, US PMI, US employment situation, the correlation between the US dollar index and LME copper price, the correlation between US interest rates and LME copper price, TC processing fees, CFTC copper positions, LME copper net long positions, SHFE copper warehouse receipts, LME copper inventory changes, COMEX copper inventory changes, and SMM social inventory [10][12][14][15][18][21][23][27][28][31][33]

Report Summary 1. Investment Rating The provided content does not mention the industry investment rating. 2. Core Viewpoints - Pure benzene: On September 2, international oil prices fluctuated higher, which supported the cost side of pure benzene and improved market sentiment. Although the futures price of pure benzene decreased, the spot price decline was small, and the basis strengthened. From the supply side, the loss of domestic pure benzene due to maintenance is gradually being offset by new production capacity, and the overall supply rhythm remains stable. However, the increase in imported pure benzene arriving at ports starting from September is expected to be a pressure point. In terms of inventory, the port inventory decreased, indicating a short - term tight balance in supply. The demand side is clearly differentiated. Overall, the rise in crude oil provides cost support, and the spot market may remain strongly volatile in the short term, but there is still a risk of a mid - term market correction as import pressure increases [3]. - Styrene: On September 2, the styrene futures price decreased, and the basis widened. Although the futures price was under pressure, the rise in crude oil drove the stabilization of pure benzene, which provided some support for the cost side of styrene. The overall operating rate of styrene remained stable, and subsequent new installations will increase the capacity utilization rate. In terms of inventory, the social inventory of styrene increased significantly, indicating continuous supply pressure. The downstream demand structure is differentiated. Overall, the rebound in oil prices drives cost stabilization, and the styrene price is expected to recover with the market fluctuations in the short term, but the contradiction between high supply and inventory accumulation will still limit its rebound space, and the weak pattern is difficult to change [4]. 3. Summary by Relevant Catalogs 3.1 Daily Market Summary - **Fundamentals** - **Prices**: On September 2, the main contract of styrene closed down 1.13% at 6934 yuan/ton, with a basis of 66 (+44 yuan/ton); the main contract of pure benzene closed down 1.23% at 5936 yuan/ton [3]. - **Costs**: On September 2, Brent crude oil closed at $64.6 per barrel (+$0.6 per barrel), WTI crude oil closed at $68.1 per barrel (+$0.6 per barrel), and the spot price of pure benzene in East China was 5810 yuan/ton (-75 yuan/ton) [3]. - **Inventory**: Styrene inventory was 17.9 tons (+1.8 tons), a 10.8% increase compared to the previous period, indicating a large inventory accumulation. The port inventory of pure benzene was 13.8 tons (-0.6 tons), a 4.2% decrease compared to the previous period [3]. - **Supply**: Styrene plants will undergo maintenance in September, and supply is expected to decrease. Currently, the weekly production of styrene is 36.9 tons (-0.2 tons), and the factory capacity utilization rate is 78.1% (-0.4%) [3]. - **Demand**: The operating rates of downstream 3S products varied. The capacity utilization rate of EPS was 58.3% (-2.6%), ABS was 70.8% (-0.3%), and PS was 59.9% (+2.4%) [3]. 3.2 Industrial Chain Data Monitoring - **Prices of styrene and pure benzene**: On September 2, the futures price of styrene decreased by 1.13% to 6934 yuan/ton, and the spot price decreased by 0.27% to 7490 yuan/ton; the futures price of pure benzene decreased by 1.23% to 5936 yuan/ton, and the spot price in East China decreased by 1.27% to 5810 yuan/ton. The prices of upstream products such as Brent crude oil, WTI crude oil, and naphtha all increased slightly [6]. - **Production and inventory of styrene and pure benzene**: From August 22 to August 29, the production of styrene in China decreased by 0.59% to 36.9 tons, and the production of pure benzene increased by 0.24% to 45.2 tons. The port inventory of styrene in Jiangsu increased by 10.84% to 17.9 tons, and the factory inventory increased by 2.35% to 21.1 tons. The national port inventory of pure benzene decreased by 4.17% to 13.8 tons [7]. - **Operating rates**: From August 22 to August 29, the capacity utilization rates of pure benzene downstream products such as styrene, caprolactam, phenol, and aniline all decreased to varying degrees, while the capacity utilization rate of PS among styrene downstream products increased by 2.4% to 59.9% [8]. 3.3 Industry News - The United States has imposed high tariffs on some Asian (especially South Korean) chemical products, leading to adjustments in the global petrochemical industry structure. South Korea has been forced to reduce its ethylene cracking capacity, and some European regions have closed factories due to high energy costs [9]. - In the first half of 2025, the overall losses of China's refining and chemical industry continued to intensify, with the total loss amount increasing by about 8.3% compared to the same period last year, and the loss in the refining and chemical sector alone exceeding 9 billion yuan, highlighting the fierce competition and profit compression in the industry [9]. - With the accelerated implementation of private refining and chemical integration projects, China's pure benzene production capacity has formed a pattern with East China as the core and coordinated development in South China and Northeast China. However, there are still many small - and medium - sized production capacities in the industry, and the overall concentration remains low [9].

Report Investment Rating - No investment rating for the industry is provided in the report. Core Viewpoints - The current crude oil market presents a game pattern of strong reality and weak expectation. Geopolitical disturbances on the supply - side provide short - term strong support, and the destocking rhythm of refined oil in China strengthens demand resilience. However, the OPEC+ meeting maintaining production policies may weaken medium - and long - term supply constraints, and the risk of Saudi Arabia releasing idle production capacity and potential impacts of India's consumption policy adjustment form upward pressure. In the short term, the SC - WTI premium may remain high. If geopolitical risks do not escalate beyond expectations, oil prices may show a high - level oscillation pattern within a range [3]. Summary by Directory 1. Daily Market Summary a. Crude Oil Futures Market Data Analysis - **Prices and Spreads**: On September 2, 2025, the price of the Shanghai Crude Oil (SC) main contract rose from 483.5 yuan/barrel to 490.4 yuan/barrel, a 1.43% increase. WTI and Brent prices remained unchanged at 64.61 and 68.16 dollars/barrel respectively. The SC - Brent spread rose from - 0.38 dollars/barrel to +0.45 dollars/barrel, a 218% increase, indicating that domestic crude oil strengthened relative to Brent. The SC - WTI spread expanded from 3.17 to 4.0 dollars/barrel, and the SC premium over WTI increased significantly. The near - far month spread (SC continuous 1 - continuous 3) rose from - 0.1 to +0.2 yuan/barrel, reflecting the tight supply expectation in the spot market [1]. - **Positions and Transactions**: Although the warehouse receipts of Chinese crude oil, fuel oil, asphalt and other varieties remained unchanged on September 2, the warehouse receipts of petroleum asphalt plants decreased by 1000 tons, implying the pick - up demand of physical enterprises [1]. b. Industrial Chain Supply - Demand and Inventory Changes Analysis - **Supply Side**: The attack on Russian refineries continued to ferment, and the CDU maintenance volume in Russia reached 6.4 million tons in August, leading to a contraction in high - sulfur fuel oil supply. The attack on a refinery in a European country disrupted regional refined oil supply and strengthened the geopolitical premium. The sanctions on Yangshan Warehouse reduced the circulation inventory of crude oil in the Chinese market. However, it is necessary to be vigilant that the OPEC+ meeting over the weekend may maintain the production policy unchanged, and the potential risk of Saudi Arabia increasing production still needs attention [2]. - **Demand Side**: The commercial inventory of refined oil in China was fully destocked. The diesel inventory decreased by 2.54% month - on - month to 102.52 million barrels, reaching a three - month low, indicating strong industrial oil demand. The supply of low - sulfur fuel oil in major bunkering ports remained tight. The expectation of a decrease in arbitrage cargoes in Singapore in the second half of September strengthened the structural demand for the switch from high - sulfur to low - sulfur in the Asia - Pacific region. India's plan to cut gasoline vehicle consumption tax may stimulate traditional energy demand, but the competition from electric vehicles may compress long - term demand growth [2]. - **Inventory Side**: China's weekly crude oil inventory decreased by 0.21% to 209.84 million barrels, declining for the fourth consecutive week. Although the data of the US strategic crude oil reserve was not updated, combined with the recent actions of the EIA, the replenishment demand still provided support for WTI. Notably, the positive SC - Brent spread indicated that the inventory pressure in the Chinese region had eased compared with Europe [2]. 2. Industrial Chain Price Monitoring a. Crude Oil - **Futures Prices**: On September 2, 2025, the SC price was 490.40 yuan/barrel, up 1.43% from the previous day; WTI was 65.62 dollars/barrel, up 1.56%; Brent was 69.07 dollars/barrel, up 1.34%; the OPEC basket price remained unchanged at 70.98 dollars/barrel [5]. - **Spot Prices**: Various crude oil spot prices showed different degrees of increase, such as Oman rising 1.27% to 71.90 dollars/barrel, and Victory rising 1.82% to 66.60 dollars/barrel [5]. - **Spreads**: The SC - Brent spread rose from - 0.38 to 0.45 dollars/barrel, a 218.42% increase; the SC - WTI spread expanded from 3.17 to 4.00 dollars/barrel, a 26.18% increase [5]. - **Other Assets**: The US dollar index rose 0.63% to 98.32; the S&P 500 index fell 0.69% to 6,415.54 points; the DAX index fell 2.29% to 23,487.33 points; the RMB exchange rate rose 0.20% to 7.15 [5]. - **Inventory and Production**: The US commercial crude oil inventory decreased by 0.57% to 41,829,200 barrels; the Cushing inventory decreased by 3.57% to 2,263,200 barrels; the US strategic reserve inventory increased by 0.19% to 40,420,100 barrels; the API inventory decreased by 0.22% to 44,982,200 barrels. The US refinery weekly operating rate decreased by 2.07% to 94.60%, and the crude oil processing volume decreased by 1.91% to 1,688,000 barrels per day [5]. b. Fuel Oil - **Futures Prices**: The FU price was 2,847.00 yuan/ton, up 0.53% from the previous day; the LU price was 3,559.00 yuan/ton, up 2.45% [6]. - **Spot Prices**: Most fuel oil spot prices increased, such as NYMEX fuel oil IF0380 in Singapore rising 2.66% to 237.16 cents/gallon [6]. - **Paper Prices**: Some paper prices remained unchanged, while some data were not updated [6]. - **Spreads**: The China high - low sulfur spread increased by 10.90% to 712.00 yuan/ton; the LU - Singapore FOB (0.5%S) spread increased by 4.22% to - 1,929.00 yuan/ton [6]. - **Inventory**: The Singapore fuel oil inventory increased by 7.33% to 24.724 million barrels [6]. 3. Industry Dynamics and Interpretations a. Supply - The sanctions on Yangshan Warehouse led to a tightening of supply. The willingness of short - sellers to deliver at Yangshan Warehouse decreased, and they closed their positions and left the market, resulting in the fuel oil price no longer being anchored to Yangshan Warehouse and the price center moving up. The attack on Russian refineries continued to disrupt the high - sulfur supply, and the supply of low - sulfur fuel oil in major bunkering ports was tight [7][8]. b. Demand - India's Tata Motors proposed to cut the consumption tax on some gasoline vehicles, which would make their prices lower than those of electric vehicles, potentially stimulating traditional energy demand [9]. c. Inventory - On September 2, the warehouse receipts of medium - sulfur crude oil futures, low - sulfur fuel oil futures, fuel oil futures, and petroleum asphalt futures warehouses remained unchanged, while the petroleum asphalt factory warehouse receipts decreased by 1000 tons. China's crude oil and refined oil inventories continued to decline [10]. d. Market Information - Brazil officially applied to join the International Energy Agency (IEA). The crude oil market closed early due to holidays, and trading was light, but the price showed an oscillating upward trend. The market was dominated by positive factors, but the concern about Saudi Arabia increasing production over the weekend limited the upside of oil prices. The spot gold price broke through the $3500 mark in the Asian session, and the market expected the OPEC+ to maintain production at the meeting over the weekend [11]. 4. Industrial Chain Data Charts - The report provides multiple data charts, including the prices and spreads of WTI and Brent first - line contracts, the SC - WTI spread statistics, the US weekly crude oil production, the number of oil rigs in the US and Canada, etc., with data sources from WIND, EIA, etc. [12][14][18]
