Report Industry Investment Rating No information provided in the content. Core Viewpoints - Crude oil prices are expected to maintain a short - term oscillatory pattern. Upside is constrained by weakening marginal demand, while downside is supported by short - term geopolitical premiums. Supply - side factors and demand - side concerns, along with the uncertainty of Russia - Ukraine peace talks, lead to a lack of continuous impetus in the capital market [4]. Summary by Relevant Catalogs 1. Daily Market Summary - On August 19, the closing price of the domestic SC crude oil futures main contract was 484.2 yuan/barrel, down 0.47% from the previous trading day. The prices of WTI and Brent crude oil futures remained flat at $62.58/barrel and $66.46/barrel respectively. The spreads of SC to Brent and WTI narrowed by $0.35. The SC continuous - to - third spread changed from contango to backwardation, with a decline of 268.18% [2]. 2. Industry Chain Supply - Demand and Inventory Changes Supply - Geopolitical conflicts and producer policies dominate supply disruptions. Oil transportation from Kazakhstan to Germany via the Russian Friendship Pipeline was briefly interrupted. Angola plans to cut exports to 994,000 barrels per day in October. The Volgograd refinery of Russia's Lukoil was suspended due to an attack, which may suppress Russia's refined oil export capacity. India's July imports of Russian crude oil decreased, but state - owned refineries turned to Middle Eastern or American oil sources, which may indirectly support OPEC+ export shares [3]. Demand - The seasonal demand peak is nearing its end. The decline in US API gasoline inventories narrowed (- 956,000 barrels), and refined oil inventories increased, indicating weakening travel demand. The US natural gas price dropped to a nine - month low, which may suppress the demand for fuel oil for power generation. The refinery operating rate increased marginally, but its support for oil prices was limited [3]. Inventory - US API data showed that in the week ending August 15, crude oil inventories decreased by 2.417 million barrels (expected to decrease by 1.587 million barrels), the decline in Cushing inventories narrowed to 112,000 barrels, and refined oil inventories increased by 535,000 barrels. The domestic Shanghai Futures Exchange's crude oil futures warehouse receipts remained unchanged at 4.767 million barrels, with no short - term delivery pressure [3]. 3. Price Trend Judgment - Crude oil prices will maintain a short - term oscillatory pattern. The upside is limited by weakening marginal demand, and the downside is supported by short - term geopolitical premiums. Supply - side factors such as infrastructure attacks and OPEC+ production cuts provide bottom support, while demand - side issues like seasonal weakness in US gasoline consumption and India's import structure adjustment raise doubts about the actual digestion capacity of the market. The repeated expectations of Russia - Ukraine peace talks intensify market wait - and - see sentiment [4]. 4. Industry Chain Price Monitoring Crude Oil - Futures prices of SC, WTI, and Brent changed on August 19 compared to August 18. Spot prices of various crude oil types also had different changes. Spreads such as SC - Brent, SC - WTI, and Brent - WTI had corresponding fluctuations. Other assets like the US dollar index, S&P 500, DAX index, and RMB exchange rate also showed changes. Inventory data of US commercial crude oil, Cushing inventories, and strategic reserves had different trends, and the US refinery operating rate and crude oil processing volume also changed [6]. Fuel Oil - Futures prices of FU, LU, and NYMEX fuel oil, as well as spot prices of various fuel oil types, had different changes. Spreads such as Singapore's high - low sulfur spread and China's high - low sulfur spread also fluctuated. Inventory data of Platts and various regions' fuel oil had corresponding trends [7]. 5. Industry Dynamics and Interpretation Supply - India's imports of Russian crude oil decreased in July. The oil supply from Kazakhstan to Germany via the Russian Friendship Pipeline was briefly interrupted. The US plans to increase tariffs on India for purchasing Russian oil. Angola will cut oil exports to 994,000 barrels per day in October. The Volgograd refinery of Russia's Lukoil was attacked and suspended operations [8][9][10]. Demand - Sinopec (Henan) Refining and Chemical Co., Ltd. increased its registered capital from 10 million RMB to about 1.84 billion RMB, with an increase of 18334% [11].

Domestic crude oil futures prices fluctuated slightly, and the warehouse receipts of various futures remained unchanged [12][13]. Market Information - The US has held separate peace talks with some European countries and Ukraine about the Russia - Ukraine issue, but direct talks between Russia and Ukraine have not taken place, and the cease - fire agreement has not made actual progress. Oil prices are expected to continue narrow - range fluctuations [14]. 6. Industry Chain Data Charts - The content provides various data charts related to the oil industry, including the prices and spreads of WTI and Brent contracts, the spread between SC and WTI, US crude oil production, OPEC crude oil production, refinery operating rates, and inventory data [15][17][19].

Report Summary 1. Investment Rating The report does not provide an investment rating for the industry. 2. Core Views - **Pure Benzene**: The supply side of pure benzene has been relatively strong recently. The supply of petroleum benzene has been stable, and the overall operating rate of hydrobenzene has increased significantly. The demand side shows structural differences, with an increase in the consumption of pure benzene in some products. However, the profit margins of downstream products are compressed, and the release of substantial incremental demand from new production capacity is slow. The inventory in East China ports has decreased slightly, and the supply and demand in the domestic market are both increasing in August - September. Although the supply - demand balance has improved marginally, high - level hidden inventory and weak terminal consumption are still concerns [3]. - **Styrene**: The styrene market remains oversupplied. New production capacity is being continuously released, and there are still large - scale plant commissioning plans in September - October. The demand improvement is limited due to insufficient terminal consumption. Although there are signs of marginal improvement in the supply - demand surplus in August - September, whether the market can maintain inventory reduction remains to be observed [4]. 3. Summary by Section 3.1. Daily Market Summary - **Fundamentals** - **Prices**: On August 19, the main contract of styrene closed down 0.06% at 7,226 yuan/ton, with a basis of 54 (+14 yuan/ton); the main contract of pure benzene closed down 0.06% at 6,182 yuan/ton. The price of Brent crude oil closed at 63.4 (+0.6 dollars/barrel), and WTI crude oil closed at 66.6 (+0.8 dollars/barrel).

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The copper market may continue to oscillate at a high level in the short term. The core drivers are the continuous fermentation of supply - side disturbances and the support from the home appliance sector in the demand side. However, the macro - sentiment is cautious, and the risk of fluctuations caused by unexpected events should be vigilant [6]. 3. Summary According to Relevant Catalogs 3.1 Copper Futures Market Data Change Analysis 3.1.1 Main Contracts and Basis - On August 15, the SHFE copper futures main contract closed at 79,080 yuan/ton, slightly down from August 12. The LME copper price also slightly declined to $9,760/ton during the same period. The domestic spot premium - discount structure was differentiated. The premium of premium copper dropped from 260 yuan/ton on August 12 to 210 yuan/ton on August 15, and the premium of flat - water copper shrank synchronously. But in North China, the spot premium - discount of electrolytic copper was boosted due to logistics restrictions near the Tianjin SCO Summit. The LME (0 - 3) discount widened to -$93.75/ton, indicating short - term supply pressure [1]. 3.1.2 Position and Trading Volume - The LME copper position increased to 271,444 lots on August 15, an increase of 2,867 lots compared to August 12. The domestic spot trading sentiment was relatively stable, and the procurement and sales sentiment indices in Shanghai were both around 3.1, with strong wait - and - see sentiment from both supply and demand sides [2]. 3.2 Analysis of Industrial Chain Supply - Demand and Inventory Changes 3.2.1 Supply Side - Overseas copper mine disturbances intensified. The Las Bambas copper mine in Peru may face operational interruptions due to the presidential election. Although MMG maintained its annual production forecast of 360,000 - 400,000 tons, transportation disruptions and inventory clearance indicated short - term supply constraints. Zambia's Q2 copper production decreased by about 4% quarter - on - quarter, mainly due to production problems of four enterprises. The annual production target of 1 million tons was under pressure. In China, policy adjustments in the recycled copper industry affected the raw material procurement of bronze strip enterprises, potentially suppressing recycled copper supply. However, Minmetals Resources' copper sales in the first half of the year increased by 51% year - on - year, partially offsetting supply - side disturbances [3]. 3.2.2 Demand Side - Downstream demand showed differentiation. The market quotation of brass rods remained flat. The production of recycled copper rod factories was suppressed by raw material shortages and policy uncertainties, and the overall production enthusiasm was average. However, the refrigeration and air - conditioning valve market continued to grow, with sales increasing by 5.7% year - on - year in the first half of the year. Policy stimulus for home appliances in the second half of the year may further boost copper consumption. Overall, the demand in the power and home appliance sectors remained stable, but the demand in the construction and industrial sectors was still weak [4]. 3.2.3 Inventory Side - On August 15, the LME inventory slightly increased to 24,560 tons, the SHFE inventory slightly decreased to 155,800 tons, and the COMEX inventory rose to 267,195 short tons. The global visible inventory generally fluctuated at a low level. The concentrated arrival of imported sources in Shanghai increased the inventory, but with the active shipment of holders, the spot premium remained firm, and inventory accumulation did not form obvious pressure [5]. 3.3 Industry Chain Price Monitoring - From August 12 to August 18, the prices of SMM:1 copper, SHFE, and LME showed slight fluctuations. The premiums of premium copper, flat - water copper, and wet - process copper changed, with the wet - process copper having a large change rate of 566.67%. The LME (0 - 3) discount increased by - 3.20%. In terms of inventory, the LME inventory increased by 3.82%, the SHFE inventory decreased by - 0.13%, and the COMEX inventory increased by 0.00% [8]. 3.4 Industry Dynamics and Interpretations - **MMG's Production**: MMG's annual production forecast for the Las Bambas copper mine in Peru remains unchanged at 360,000 - 400,000 tons, but the presidential election may cause operational interruptions [9]. - **Qingyuan Jiangtong's PV Project**: On August 15, Jiangxi Copper (Qingyuan) Co., Ltd.'s 2540.65 - kilowatt distributed photovoltaic power generation project was officially connected to the grid, with an annual power generation of 2.5 million kilowatt - hours, saving 1,000 tons of standard coal and reducing 2,492 tons of carbon dioxide emissions annually [10]. - **SMM Copper News**: Due to the approaching Tianjin SCO Summit, logistics restrictions in North China boosted the spot premium - discount of electrolytic copper [10]. - **Zambia's Copper Production**: Zambia's Q2 copper production decreased by about 4% quarter - on - quarter, and the annual production target of 1 million tons is at risk [11]. - **Recycled Copper Policy**: Policy adjustments in the recycled copper industry may affect the raw material procurement of bronze strip enterprises [12].

Report Summary 1. Report Industry Investment Rating No information is provided regarding the report industry investment rating. 2. Core Viewpoints of the Report - The listing of pure benzene futures/options allows caprolactam (CPL) enterprises to shift from being "passive price takers" to "active cost managers". By focusing on procurement price locking (going long on BZ), combined with rolling position transfers and basis point pricing, and using options to set a cost ceiling, profit fluctuations can be contained within an "operationally acceptable" range [2][3][24]. - The key is to closely align spot plans, futures positions, and profit accounting to form a complete, reviewable, auditable, and optimizable process loop, rather than "guessing price directions" [3][24]. 3. Summary by Relevant Catalogs I. Pure Benzene Industry Chain and Pricing Logic - **Pure Benzene**: It is a basic organic raw material in the petrochemical industry chain with wide - ranging downstream applications. Its price fluctuations significantly impact the cost of CPL production enterprises. Supply is affected by refinery operating rates, import arbitrage windows, and crude oil trends. Demand is mainly from styrene (nearly 50%) and CPL (about 15% - 20%). Its price is highly correlated with crude oil, PX, and styrene, with obvious cyclical fluctuations and relatively limited basis fluctuations in monthly and quarterly dimensions, providing a basis for hedging [4]. - **Caprolactam (CPL)**: It is the core raw material for producing polyamide 6 (PA6). Raw material costs account for over 70% of CPL production costs, with pure benzene having the highest proportion. Its price is driven by pure benzene, energy costs, downstream demand, and industry supply - demand patterns, and there is a certain price - spread transmission relationship with pure benzene [7]. II. Price Linkage Analysis between Pure Benzene and CPL - **Historical Price - Spread Relationship**: Since 2020, the prices of pure benzene and CPL have been highly correlated, with correlation coefficients generally between 0.7 - 0.9, and the CPL - BZ price spread has weakened year by year. In 2025, the average price spread was only 3,201 yuan/ton [8]. - **Profit Transmission**: There are three types of profit transmission: upstream - driven (crude oil price increase leads to reduced CPL profits), downstream - demand - driven (strong demand for spinning and engineering plastics repairs CPL profits), and import - window - driven (opening or closing of the import arbitrage window affects CPL spot pricing) [10]. III. Hedging Strategy Design for Pure Benzene and CPL - **Hedging Principles**: The core goal of hedging is to lock in the enterprise's future production profits. Strategies include full - hedging (maximally hedges raw material price increase risks but loses potential benefits from price drops), proportional - hedging (balances risk hedging and profit elasticity), rolling - hedging (spreads the risk of entry timing but requires high risk - control and fund - management capabilities), and cross - hedging (using other related varieties, but may be ineffective when correlations are insufficient) [11][12][13][14]. - **Calculation of Hedging Lots**: The number of hedging lots = external pure benzene procurement volume ÷ contract unit × hedging ratio. There is a dynamic adjustment mechanism based on production and sales plans, price spreads between spot and futures, and market expectations [15]. - **Key Points of Strategy Implementation**: Select the main contract or near - month contracts with good liquidity, set a margin occupancy cap, and evaluate hedging effectiveness by comparing simulated profits with non - hedged profits [16]. IV. Case Calculation and Profit Scenarios - **Price - Spread Calculation**: Using the "CPL - pure benzene" price spread as an approximate measure of profit can guide hedging ratios and risk management. Different price - spread scenarios are simulated, and a profit warning line of 2,800 yuan/ton is set. Different hedging strategies are recommended based on different price - spread ranges [17][18][19][20]. - **Risk Situations and Strategy Adjustments**: Different risks such as spatial mismatch, time mismatch, excessive basis weakening or strengthening, and simultaneous fluctuations in nominal price spreads and basis are considered, and corresponding strategies are proposed [23].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core View of the Report - Over the next 1 - 2 weeks, the lithium carbonate futures market may shift to a wide - range, volatile, and bullish pattern. Although supply disturbances have boosted market bullish sentiment, the impact of current mine shutdowns on actual production is yet to be seen, and lithium salt plants maintain high operating rates, so the spot market still faces inventory pressure. On the demand side, the growth rate of new energy vehicle sales is slowing down, and the "anti - involution" initiative in the battery industry chain restrains the mid - stream's impulse to expand production, so there is a risk of revising the peak - season expectations. Attention should be paid to the marginal changes in policy implementation and the progress of mine rectification in Jiangxi [3]. Group 3: Summary According to the Table of Contents 1. Daily Market Summary - **Analysis of Lithium Carbonate Futures Market Data** - On August 18, the price of the lithium carbonate main contract rose to 89,240 yuan/ton; the basis weakened from - 3,600 yuan/ton to - 5,940 yuan/ton, indicating that the market's pricing of the supply - tightening expectation increased [1]. - The open interest of the main contract increased by 19,967 lots to 421,106 lots, and the trading volume increased to 1.036328 million lots. The simultaneous expansion of volume and open interest shows that the divergence among funds on the direction of lithium prices has intensified, and the market's gambling sentiment has heated up [1]. - **Analysis of Industrial Chain Supply - Demand and Inventory Changes** - **Supply side**: The shutdown of Ningde Times' Jianxiawo Mine in Jiangxi has triggered market concerns about the shortage of lithium mica supply. Coupled with the regulatory pressure on local mines to complete the re - application of ore types by September 30, the uncertainty of lithium ore supply has increased. However, the prices of spodumene concentrate and lithium mica concentrate are stable at 940 yuan/ton and 990 yuan/ton respectively, and the weekly capacity utilization rate of lithium carbonate remains flat at 63.92%. The short - term actual supply has not significantly shrunk [2]. - **Demand side**: The retail performance of new energy vehicles is moderate, with the year - on - year growth rate dropping to 6% from August 1 - 10, indicating marginal weakening pressure on demand. However, the price of lithium hexafluorophosphate increased by 0.54% week - on - week to 55,500 yuan/ton, and the price of power ternary materials slightly increased by 0.42% to 119,695 yuan/ton, indicating that there is still some support for downstream inventory - building demand [2]. - **Inventory and warehouse receipts**: Lithium carbonate inventory decreased slightly by 162 physical tons to 142,256 tons (a decrease of 0.11%), and the absolute value is still at a high level this year. The number of warehouse receipts has not changed abnormally, and the overall inventory pressure has not been substantially relieved [2]. - **Market Price** - Future 1 - 2 weeks, the lithium carbonate futures market may enter a wide - range, volatile, and bullish pattern. Although supply disturbances have boosted market bullish sentiment, the impact of current mine shutdowns on actual production is yet to be seen, and the spot market still faces inventory pressure. On the demand side, the growth rate of new energy vehicle sales is slowing down, and the "anti - involution" initiative in the battery industry chain restrains the mid - stream's impulse to expand production, so there is a risk of revising the peak - season expectations. Attention should be paid to the marginal changes in policy implementation and the progress of mine rectification in Jiangxi [3]. 2. Industrial Chain Price Monitoring - From August 15 to August 18, the price of the lithium carbonate main contract rose from 86,900 yuan/ton to 89,240 yuan/ton, an increase of 2,340 yuan or 2.69%. The basis weakened from - 3,600 yuan/ton to - 5,940 yuan/ton, a decrease of 2,340 yuan or 65%. The open interest of the main contract increased from 401,139 lots to 421,106 lots, an increase of 19,967 lots or 4.98%. The trading volume of the main contract increased from 868,811 lots to 1,036,328 lots, an increase of 167,517 lots or 19.28% [5]. - The market price of battery - grade lithium carbonate remained unchanged at 83,300 yuan/ton. The market prices of spodumene concentrate and lithium mica concentrate remained unchanged at 940 yuan/ton and 990 yuan/ton respectively. The price of lithium hexafluorophosphate increased from 55,200 yuan/ton to 55,500 yuan/ton, an increase of 300 yuan or 0.54%. The price of power ternary materials increased from 119,195 yuan/ton to 119,695 yuan/ton, an increase of 500 yuan or 0.42%. The price of power lithium iron phosphate increased from 35,655 yuan/ton to 36,170 yuan/ton, an increase of 515 yuan or 1.44% [5]. - From August 8 to August 15, the capacity utilization rate of lithium carbonate remained unchanged at 63.92%. Lithium carbonate inventory decreased from 142,418 physical tons to 142,256 physical tons, a decrease of 162 physical tons or 0.11%. The price of 523 cylindrical ternary cells increased from 4.31 yuan/piece to 4.32 yuan/piece, an increase of 0.01 yuan or 0.23%. The price of 523 square ternary cells increased from 0.38 yuan/Wh to 0.39 yuan/Wh, an increase of 0.00 yuan or 0.26%. The price of 523 soft - pack ternary cells remained unchanged at 0.40 yuan/Wh. The price of square lithium iron phosphate cells remained unchanged at 0.32 yuan/Wh. The price of cobalt - acid lithium cells increased from 5.53 yuan/Ah to 5.55 yuan/Ah, an increase of 0.02 yuan or 0.36% [5]. 3. Industry Dynamics and Interpretation - **Spot Market Quotation (August 18)**: The SMM battery - grade lithium carbonate index price was 84,794 yuan/ton, a increase of 2,069 yuan/ton compared with the previous working day. The price range of battery - grade lithium carbonate was 82,500 - 86,700 yuan/ton, with an average price of 84,600 yuan/ton, a increase of 1,900 yuan/ton compared with the previous working day. The price range of industrial - grade lithium carbonate was 81,600 - 83,000 yuan/ton, with an average price of 82,300 yuan/ton, a increase of 1,900 yuan/ton compared with the previous working day. Affected by the news that a lithium salt production enterprise in Qinghai may face shutdown due to the mining license issue, the futures price continued to rise, breaking through the 90,000 - yuan/ton mark at the highest. The downstream purchasing enthusiasm continued to increase, and the market activity increased. Due to the rigid - demand purchasing needs of some downstream enterprises and the general reluctance - to - sell sentiment of upstream and traders, the center of the spot transaction price of lithium carbonate continued to move up significantly. Under the dual effects of the supply - tightening expectation and the peak - demand season, the spot price of lithium carbonate is expected to have room for an upward movement, and the price center may continue to move up in the short term. The trading sentiment factor of lithium carbonate on this day was 2.31, the upstream shipping sentiment factor was 2.67, and the downstream purchasing sentiment factor was 2.05. The downstream purchasing sentiment factor increased compared with the previous working day, and the upstream shipping sentiment factor remained relatively stable [6]. - **Downstream Consumption Situation (August 13)**: According to the data of the Passenger Car Association, from August 1 - 10, the retail sales of new energy vehicles in the national passenger car market were 262,000 units, a year - on - year increase of 6% and a month - on - month increase of 6%. The retail penetration rate of the national new energy market was 57.9%. The cumulative retail sales this year were 6.717 million units, a year - on - year increase of 28%. From August 1 - 10, the wholesale sales of new energy vehicles by national passenger car manufacturers were 229,000 units, a year - on - year increase of 15% and a month - on - month decrease of 2%. The wholesale penetration rate of new energy manufacturers was 56.8%. The cumulative wholesale sales this year were 7.862 million units, a year - on - year increase of 35% [6]. - **Industry News** - August 15: Ningde Times' Jianxiawo Mine, one of the largest lithium mica mines in Yichun, announced a shutdown due to the expiration of the mining license, which will directly affect the change in lithium carbonate prices. Local mines in Yichun mainly mine ceramic soil and tantalum - niobium ore, but the new mining law revision tends to determine the ore type based on the actual economic behavior. There are a total of eight mines in the same situation, and local authorities require them to re - apply before September 30 this year [8]. - August 13: An "anti - involution" storm is sweeping through the entire lithium - battery industry chain. On August 12, the Lithium Industry Branch of the China Non - Ferrous Metals Industry Association issued an initiative for the healthy development of the lithium industry, calling on the entire industry chain to jointly resist vicious competition and promote the high - quality development of the lithium industry.
