Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - Copper prices are facing a short - term high - level correction due to the cooling of macro - sentiment. The upside space of copper prices is limited by the high - level dollar and escalating trade frictions, and further breakthroughs require macro - level support. The focus in the near term is on US inflation and employment data before the Fed's interest - rate meeting and the final interest - rate cut decision [1][6] - It is expected that copper prices will fluctuate in the future, with the range possibly around 78,500 - 80,000 yuan/ton [34] Group 3: Summary of Each Related Section 1. Daily Market Summary a. Copper Futures Market Data Variation Analysis - **Main Contract and Basis**: SHFE copper prices slightly declined from 79,450 yuan/ton on August 21st to 79,330 yuan/ton on August 27th, showing a narrow - range oscillation. The premium structure of copper was differentiated, with the premium of high - grade copper rising from 165 yuan/ton on August 26th to 230 yuan/ton, indicating a tight supply of high - grade copper in the spot market. The premiums of flat - water copper and wet - process copper remained low, and the supply of ordinary copper was relatively stable. The LME copper (0 - 3) discount widened to - 84.82 dollars/ton, suggesting the existence of overseas hidden inventory pressure [1] - **Position and Trading Volume**: LME copper inventories decreased for four consecutive weeks, dropping to 21,287 tons on August 27th, a 10.4% decrease from the previous week, with an accelerating de - stocking speed. SHFE inventories slightly increased by 1,100 tons to 156,100 tons, indicating limited inventory accumulation pressure in China. In terms of positions, the LME copper position increased to 268,800 lots, intensifying the long - short game, but the high - level oscillation of the dollar index suppressed short - term speculative sentiment [2] b. Analysis of Industrial Chain Supply - Demand and Inventory Changes - **Supply Side**: The expected adjustment of the recycled copper policy has led smelters to stockpile cold materials in advance, and the pressure on the rough copper processing fee indicates that the raw material supply in September may tighten. Aurubis signed a long - term contract for 75,000 tons/year of copper concentrate with Troilus Gold to hedge policy risks in the long - term raw material end. Currently, the supply of high - quality imported copper is still tight, and the circulation of wet - process copper is scarce, supporting the spot premium [3] - **Demand Side**: Downstream consumption shows structural differentiation. The demand for power/long - term order pick - up is stable, but the zero - order procurement is significantly suppressed by the high copper price. The procurement sentiment index in Shanghai monitored by SMM is only 3.16/5, and the high - price copper has a negative feedback on the demand in the construction/home appliance and other fields. The new US tax rule on small - parcel imports may further suppress the export orders of electronic consumer goods [4] - **Inventory Side**: LME inventories are accelerating de - stocking to a near - three - year low, and the domestic social inventory pressure is controllable. However, the limited replenishment of imported resources and the regional outflow of warehouse receipts strengthen the short - term spot tight pattern [5] c. Market Summary - The stockpiling of cold materials on the supply side exacerbates the spot tightness, and the continuous de - stocking of LME provides bottom support. However, the high - level dollar and escalating trade frictions suppress risk appetite, limiting the upside space of copper prices [6] 2. Industrial Chain Price Monitoring - On August 27th, 2025, compared with August 21st, SMM:1 copper (premium copper) prices slightly decreased, with the premium significantly increasing; flat - water copper premiums slightly increased; wet - process copper premiums remained unchanged. LME copper prices and SHFE copper prices both had small fluctuations. LME inventories decreased, while SHFE and COMEX inventories increased [8] 3. Appendix: Big Model Inference Process - The change in the recycled copper policy may affect the cold - material supply of electrolytic copper smelters, leading to a decline in the processing fees of rough copper and anode plates. The outflow of SHFE warehouse receipts in Guangdong and Jiangsu regions and the stable inventory in Shanghai. The continuous decrease in LME copper inventories may reflect supply tightness. Macroscopically, the US tariff policy and Fed personnel changes have caused market concerns. The dollar index has declined but remains at a high level, which may put pressure on copper prices. Fundamentally, the supply of high - quality copper has been slightly supplemented, but wet - process copper is scarce, and the spot supply is tight. On the consumption side, the high copper price has suppressed the procurement sentiment [33] - In the market data variation analysis, the SHFE price slightly decreased, and the premium of premium copper strengthened, indicating possible spot supply tightness. In terms of position and trading volume, the LME position increased, but the SHFE inventory increased, and trading volume may shrink due to price fluctuations. In the industrial chain supply - demand and inventory analysis, on the supply side, smelters stockpile due to policy changes, and the rough copper processing fee decreases, which may affect future supply. The agreement of Aurubis increases supply, but the specific volume depends on time. On the demand side, downstream procurement is mainly for rigid needs, and high copper prices suppress consumption, but there may still be demand in the power, construction and other fields. On the inventory side, LME inventories continue to decrease, showing de - stocking, while SHFE inventories slightly increase, possibly due to regional differences [34]

Report Summary 1. Industry Investment Rating No industry investment rating was provided in the report. 2. Core View The report analyzes the PX, PTA, and polyester markets, highlighting that cost - side weakness has led to PX and PTA price corrections, and the focus should be on the demand - side recovery. The polyester industry chain shows a pattern of weak supply and demand but with strengthened cost support, and is expected to maintain a volatile consolidation pattern [1][4]. 3. Summary by Directory Daily Market Summary - **PTA & PX**: On August 27, the PX main contract closed at 6940.0 yuan/ton, down 0.77% from the previous trading day, with a basis of - 97.0 yuan/ton. The PTA main contract closed at 4824.0 yuan/ton, down 0.94% from the previous trading day, with a basis of 56.0 yuan/ton. The supply of PX may increase due to lower crude oil costs and the restart of some Asian plants, while PTA's supply has potential elasticity. The demand for polyester provides support for PTA, and the inventory of PTA factories is at a low level [2][3]. - **Polyester**: On August 27, the short - fiber main contract closed at 6572.0 yuan/ton, down 0.76% from the previous trading day. The polyester industry chain shows a pattern of weak supply and demand but with strengthened cost support.

Report Industry Investment Rating - Not provided in the given content Core Viewpoints of the Report - In the short term, the lithium carbonate market is expected to continue its weak and volatile pattern. The marginal improvement on the supply side and the insufficient realization of the peak - season demand on the demand side exert downward pressure, but the support comes from the resilience of new energy vehicle demand and inventory reduction. The resumption progress of Jiangxi mines and the change in downstream restocking rhythm should be closely monitored, and the new energy vehicle sales data in September may be the key variable to break the current balance [3] Summary by Relevant Catalogs 1. Daily Market Summary a. Lithium Carbonate Futures Market Data Changes - On August 27, the closing price of the lithium carbonate main contract was 78,860 yuan/ton, a slight decline of 0.2% from the previous trading day, with short - term directional divergence. The basis was 2,640 yuan/ton, a slight weakening of 40 yuan compared to the previous day, and the basis center in the past week showed a downward trend, indicating that the downward pressure on the spot price was transmitted to the futures market [1]. - The main contract's open interest increased slightly by 0.52% to 351,000 lots, while the trading volume significantly rebounded by 30.4% to 729,000 lots, indicating intensified short - term capital games and fierce competition between long and short sides around key price levels [1] b. Industry Chain Supply - Demand and Inventory Changes - Supply side: The capacity utilization rate of lithium carbonate has rebounded for two consecutive weeks, reaching 66.41% in the week of August 22. The accelerated release of lithium production from salt lakes partially offset the impact of the suspension of lithium mica mines in Yichun, Jiangxi. However, potential supply disruptions due to the re - application for mining licenses by Jiangxi mines before the end of September should be noted [2]. - Demand side: Downstream demand was divided. According to the Passenger Car Association, the year - on - year growth rates of new energy vehicle retail and wholesale in August were 9% and 18% respectively, indicating demand resilience. However, the cathode material market was weak, with the price of power - type lithium iron phosphate dropping for four consecutive weeks to 35,590 yuan/ton, the price of ternary materials remaining stable, and lithium hexafluorophosphate remaining flat for three consecutive weeks. Mid - stream procurement became more cautious, and the stocking demand weakened [2]. - Inventory and warrants: Lithium carbonate inventory decreased slightly by 713 tons to 141,500 tons, but it remained at a relatively high level in the past five weeks [2] c. Market Summary - In the short term, the lithium carbonate market is expected to continue its weak and volatile pattern. The marginal improvement on the supply side and the insufficient realization of the peak - season demand on the demand side exert downward pressure, but the support comes from the resilience of new energy vehicle demand and inventory reduction. The resumption progress of Jiangxi mines and the change in downstream restocking rhythm should be closely monitored, and the new energy vehicle sales data in September may be the key variable to break the current balance [3] 2. Industry Chain Price Monitoring - The price of the lithium carbonate main contract decreased from 79,020 yuan/ton to 78,860 yuan/ton, a decline of 0.2%. The basis decreased from 2,680 yuan/ton to 2,640 yuan/ton, a weakening of 1.49%. The open interest of the main contract increased by 0.52% to 351,322 lots, and the trading volume increased significantly by 30.39% to 729,645 lots. The market price of battery - grade lithium carbonate decreased by 0.24% to 81,500 yuan/ton. The price of power - type lithium iron phosphate decreased by 0.08% to 35,590 yuan/ton, while the prices of ternary materials and lithium hexafluorophosphate remained unchanged [5] - The capacity utilization rate of lithium carbonate increased from 63.92% to 66.41%, an increase of 3.9%. Lithium carbonate inventory decreased by 0.5% to 141,543 tons. The prices of some battery cells showed small fluctuations, with the cobalt - acid lithium cell price increasing by 3.6% [5] 3. Industry Dynamics and Interpretation a. Spot Market Quotes - On August 27, the SMM battery - grade lithium carbonate index price was 81,671 yuan/ton, a decrease of 68 yuan/ton from the previous working day. The average price of battery - grade lithium carbonate was 81,600 yuan/ton, a decrease of 100 yuan/ton from the previous working day, and the average price of industrial - grade lithium carbonate was 79,300 yuan/ton, also a decrease of 100 yuan/ton from the previous working day. Due to pre - stocking by some downstream material factories, the procurement scale this week was smaller than last week. The current downstream procurement attitude is cautious, and they are waiting for further price drops. During the "Golden September and Silver October" peak season, the downstream demand has certain rigid support, and the short - term spot price of lithium carbonate is expected to remain relatively high and continue to fluctuate within a range [6] b. Downstream Consumption Situation - From August 1 - 17, the retail volume of the national new energy passenger vehicle market was 502,000 units, a year - on - year increase of 9% and a month - on - month increase of 12%. The retail penetration rate was 58.0%, and the cumulative retail volume this year was 6.958 million units, a year - on - year increase of 28%. The wholesale volume of the national new energy passenger vehicle market was 474,000 units, a year - on - year increase of 18% and a month - on - month increase of 10%. The wholesale penetration rate was 56.4%, and the cumulative wholesale volume this year was 8.108 million units, a year - on - year increase of 34% [7] c. Industry News - Since the official suspension of the Ningde Times' Jiangxi Yichun Jianxiawo mining area on August 10, the "butterfly effect" has spread throughout the industry chain [8]. - On August 18, Lanxiao Technology won the bid for the adsorption system of the expansion and transformation project of the comprehensive utilization of old brine lithium extraction from the Lop Nur Salt Lake of Xinjiang Guotou Lithium Industry Co., Ltd., with a bid amount of 35.7712 million yuan. This project will help the company improve its market share and technical control ability in the salt lake lithium extraction industry [9]. - On August 15, the Jianxiawo mining area of Ningde Times stopped production due to the expiration of the mining license. Eight local mines in Yichun need to re - apply for mining licenses before September 30 this year [9] 4. Appendix: Large - Model Inference Process - Market data analysis: The main contract price decreased slightly, the basis weakened, the open interest increased slightly, and the trading volume increased significantly, indicating intensified market competition between long and short sides [30]. - Industry chain analysis: On the supply side, the capacity utilization rate increased, but the suspension of the Yichun mining area may cause supply shortages, which may be partially offset by new salt lake lithium extraction projects. On the demand side, new energy vehicle sales increased, but the price of battery - grade lithium carbonate decreased, indicating more cautious downstream procurement. The inventory decreased slightly, which may support the price [30][31][32]. - Price trend judgment: In the next one to two weeks, the market may maintain a low - level volatile pattern. The pressure comes from increased supply and demand hesitation, but the inventory decline may limit the decline [32]

Report Industry Investment Rating - No relevant content provided Core View of the Report - In the next 1 - 2 weeks, the copper market may remain oscillating at a high level, with the core drivers being the marginal weakening of supply - demand and the differentiation of macro - sentiment. The upward space for copper prices is limited due to the supply - side relief of tightness expectations, demand - side drag from high - price suppression of procurement and weak terminal orders, and the suppression of risk appetite by the rebound of the US dollar [6]. Summary According to Relevant Catalogs 1. Daily Market Summary Copper Futures Market Data Change Analysis - **Main Contract and Basis**: On August 25, the SHFE main contract closed at 79,360 yuan/ton, a slight decline of 0.11% from the previous trading day. In terms of spot premium and discount, the premium of premium copper dropped to 165 yuan/ton, that of flat - water copper decreased to 95 yuan/ton, and the premium of wet - process copper dropped by 50% to 15 yuan/ton. The LME (0 - 3) maintained a discount of 78.38 US dollars/ton, with weak support at the spot end [1]. - **Position and Trading Volume**: LME inventory continuously declined, reaching 22,917 tons on August 25, a new low in nearly a month, while domestic SHFE inventory slightly decreased to 155,000 tons. The narrowing of import losses to 250 yuan/ton repaired the inverted spread between the domestic and foreign markets, which may limit the activity of arbitrage funds [2]. Industry Chain Supply - Demand and Inventory Change Analysis - **Supply Side**: There are both short - term disturbances and long - term increments. Codelco resumed production at the El Teniente copper mine, strengthening the expectation of supply recovery in Chile. In China, Tibet Summit's copper production increased by 29.9% year - on - year, but Xingye Yinxing's copper production decreased by 44.2% year - on - year, showing a differentiation in mine expansion. Reduced import arrivals made the recent supply tight, but the gradual replenishment of domestic electrolytic copper may ease the gap [3]. - **Demand Side**: There is a structural differentiation in domestic demand, and the suppression effect of high copper prices is significant. The domestic sales of air conditioners increased by 14.3% year - on - year, and the computing power infrastructure drove copper use in the intelligent field. However, the weak orders of cable enterprises and the 5.44% decrease in the finished product inventory of refined copper rods reflected the insufficient carrying capacity of the real economy. The weakening of export demand further restricted the consumption elasticity [4]. - **Inventory Side**: The mainstream copper inventory in China dropped to 123,000 tons on August 25, but SMM predicted that the rebound of import arrivals this week and the consumption suppression by high prices would drive the inventory to rebound month - on - month. The LME inventory overseas continued to decline, but the COMEX inventory reached 272,500 short tons, and the pressure of hidden inventory still needed to be vigilant [5]. Market Summary - In the next 1 - 2 weeks, the copper market may remain oscillating at a high level, with the core drivers being the marginal weakening of supply - demand and the differentiation of macro - sentiment. The supply - side relief of tightness expectations and the demand - side drag, along with the suppression of risk appetite by the rebound of the US dollar, limit the upward space for copper prices [6]. 2. Industry Chain Price Monitoring - On August 26, 2025, the price of SMM:1 copper was 79,780 yuan/ton, a 0.36% increase from August 25. The premiums of premium copper, flat - water copper, and wet - process copper all decreased, with the wet - process copper's premium dropping by 50%. The SHFE price was 79,360 yuan/ton, a 0.11% decrease from August 25. The LME inventory decreased by 830 tons, a 3.5% decline [8]. 3. Industry Dynamics and Interpretation - As of August 25, the SMM national mainstream copper inventory decreased by 0.87 million tons month - on - month to 12.30 million tons, and it is expected to rebound this week. Codelco announced the resumption of production at some mines in Chile. In July 2025, China's copper product output was 2.169 million tons, a year - on - year increase of 8.3%. Last week, some refined copper rod enterprises reduced production due to maintenance, with raw material inventory decreasing by 2.31% and finished product inventory decreasing by 5.44%. The ICSG reported a global copper surplus of 36,000 tons in June [9]. 4. Industry Chain Data Charts - The report provides multiple data charts, including China PMI, US PMI, US employment situation, dollar index and LME copper price correlation, US interest rate and LME copper price correlation, TC processing fees, CFTC copper positions, LME copper net long positions, Shanghai copper warehouse receipts, LME copper inventory changes, COMEX copper inventory changes, and SMM social inventory [10][12][14][15][19][22][24][28][29][32] Appendix: Big Model Inference Process - The analysis of copper futures market data includes market data (price and basis changes, inventory changes), industry chain supply - demand (supply increase from mine resumption and domestic production, demand affected by high prices and export decline), and price trend judgment (high - level oscillation affected by supply, demand, and macro factors such as the US dollar and crude oil). The copper price is expected to be in the range of 78,500 - 80,500 yuan [36][37]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - Despite the oil price correction, the PX market remains strong due to increased supply elasticity in the short - term [2] - The PTA market faces supply - side pressure in the long - run, and its demand may be negatively affected by weak terminal orders [3] - The polyester market shows a weak recovery in terminal demand, but there are concerns about inventory accumulation suppressing profit margins [5] 3. Summary by Relevant Catalogs 3.1 Daily Market Summary 3.1.1 PTA&PX - On August 26, the PX主力合约 closed at 6994.0 yuan/ton, up 0.34% from the previous trading day, with a basis of - 162.0 yuan/ton. The PTA主力合约 closed at 4870.0 yuan/ton, up 0.16%, with a basis of 10.0 yuan/ton [3] - Cost - end: On August 26, the Brent oil主力合约 closed at 68.2 dollars/barrel, and WTI at 64.74 dollars/barrel [3] - Demand - end: On August 26, the total transaction volume of the Light Textile City was 547.0 million meters, and the 15 - day average transaction was 514.93 million meters [3] - Supply - end: The PX supply side faces loosening pressure, and the cost support weakens during the international oil price decline. The PTA supply side has short - term positive factors but long - term pressure [3] - Demand - end: The downstream polyester start - up is at a low level, and the terminal order improvement is limited. The contradiction between high polyester start - up and weak terminals remains [3] - Inventory - end: The current PTA social inventory is decreasing, but it may turn to inventory accumulation if demand does not improve significantly [4] 3.1.2 Polyester - On August 26, the short - fiber主力合约 closed at 6622.0 yuan/ton, up 0.39% from the previous trading day. The East China market spot price was 6585.0 yuan/ton, unchanged from the previous day [5] - Supply - side: From August 18 to August 26, PX and PTA futures prices showed an upward trend, with PX rising 234 yuan/ton (+3.46%) and PTA rising 124 yuan/ton (+2.61%) [5] - Demand - side: The 15 - day moving average trading volume of the China Light Textile City increased from 482.73 million meters to 514.93 million meters (+6.67%), indicating a weak recovery in terminal demand [5] - Inventory - side: The polyester short - fiber inventory is 6.65 days, higher than the five - year average of 4.96 days (+34.1%), while the polyester filament inventories are generally lower than historical averages [5] 3.2 Industrial Chain Price Monitoring - PX futures: The主力合约 price, trading volume, and open interest all increased on August 26 compared to the previous day [6] - PX spot: The China main port CFR price remained unchanged, while the South Korea FOB price increased slightly [6] - PTA futures: The主力合约 price, trading volume, and open interest all increased, and the basis decreased [6] - PTA spot: The China main port CFR price remained unchanged [6] - Short - fiber futures: The主力合约 price, trading volume, and open interest all increased, and the basis decreased significantly [6] - Short - fiber spot: The East China market mainstream price remained unchanged [6] - Other industrial chain prices: Most prices remained stable, with slight changes in some products such as polyester bottle chips [6][7] - Processing spreads: The naphtha processing spread increased, while the PTA processing spread decreased slightly [7] - Light Textile City trading volume: The total volume increased, with short - fiber fabric trading volume rising significantly and long - fiber fabric trading volume decreasing [7] - Industrial chain load rates: The load rates of PTA factories, polyester factories, and Jiangsu and Zhejiang looms remained unchanged [7] - Inventory days: The inventory days of polyester short - fiber, POY, FDY, and DTY all decreased [7] 3.3 Industry Dynamics and Interpretation 3.3.1 Macroeconomic Dynamics - Multiple statements were made regarding the Fed's possible interest - rate cuts and the geopolitical situation, which may affect the market sentiment [8] 3.3.2 Supply - Demand (Demand) - On August 26, the total trading volume of the Light Textile City was 547.0 million meters, a 1.11% increase from the previous day [9] 3.4 Industrial Chain Data Charts - The report provides multiple data charts related to PX, PTA, short - fiber futures and spot prices, basis, capacity utilization, processing profits, and trading volumes [10][12][14]

1. Report Industry Investment Rating No information provided regarding the report industry investment rating 2. Core View of the Report The short - term trend of crude oil is expected to be weak with oscillations, and attention should be paid to the persistence of geopolitical events. The supply side presents a mix of positive and negative factors, and the demand side is at the end of the peak season with refinery profits under pressure. The significant inventory build - up and the deepening of the contango structure intensify the pressure on near - term prices. The upside potential of oil prices is restricted by inventory pressure and marginal supply increase. If Russia's export plan is actually realized or the geopolitical premium fades, oil prices may continue the weak oscillatory trend, with the short - term support for WTI at $62 - 63 per barrel and resistance at $65 per barrel [8] 3. Summary by Relevant Catalogs 3.1 Daily Market Summary 3.1.1 Crude Oil Futures Market Data Change Analysis - **主力合约与基差**: As of August 26, the SC crude oil continuous contract price slightly declined to 496.1 yuan per barrel, up 0.65% from the previous day, but closed at 487 yuan per barrel at night, down 2.19% from the day session. WTI and Brent main contracts fell 2.21% to $63.31 and $66.69 per barrel respectively. The SC - Brent and SC - WTI spreads strengthened to $2.58 and $5.96 per barrel respectively, and the Brent - WTI spread slightly narrowed to $3.38 per barrel. The SC far - month contango (spread between contract 1 and contract 3) widened to - 4.3 yuan per barrel, indicating increasing pressure on the spot side [2] - **持仓与成交**: The SC crude oil main contract fluctuated sharply, with prices rising first and then falling, and the night - session decline exceeded 2%. The geopolitical disturbances and Fed policy expectations drove capital fluctuations. The medium - sulfur crude oil futures warehouse receipts increased by 954,000 barrels to 5.721 million barrels on August 26, and fuel oil warehouse receipts also increased by 26,600 tons, reflecting the surplus pressure in the physical market [3] 3.1.2 Analysis of Industrial Chain Supply - Demand and Inventory Changes - **供给端**: Iraq's crude oil exports in July reached 104.7 million barrels (3.38 million barrels per day). Russia planned to increase its western port crude oil exports by 200,000 barrels per day in August, but 17% of its refining capacity (1.1 million barrels per day) was disrupted by Ukrainian drone attacks. Iran's exports declined in August due to US sanctions and logistics constraints, and Alberta in Canada sought investment in the Japanese refining industry [4] - **需求端**: The interruption of Russia's refining capacity and the seasonal peak in gasoline demand may suppress the actual increase in crude oil re - exports. Global refinery margins remained low, and attention should be paid to the trends of US strategic reserves and the end of the seasonal demand in the Northern Hemisphere [5] - **库存端**: US Cushing and commercial crude oil inventories continued to accumulate. The medium - sulfur crude oil futures warehouse receipts increased significantly, and fuel oil warehouse receipts also rose, reflecting the surplus pressure in the spot market. The interruption of Russian refining may indirectly increase overseas crude oil inventory pressure [6] 3.2 Industrial Chain Price Monitoring 3.2.1 Crude Oil - **期货价格**: SC price was 496.1 yuan per barrel, WTI was $63.31 per barrel, and Brent was $66.69 per barrel.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The short - term lithium carbonate market may fluctuate widely within the current range. The contraction expectation caused by CATL's production suspension on the supply side is being partially offset by the increase in salt - lake lithium extraction and the recovery of imports. Although the downstream is in the peak season, the procurement rhythm has become cautious due to previous stockpiling, and the continuous pressure on cathode material prices weakens demand elasticity. Lithium carbonate futures may continue to fluctuate within the high - level range [3]. Group 3: Summary by Relevant Catalogs 1. Daily Market Summary a. Lithium Carbonate Futures Market Data Changes Analysis - On August 26, the main contract of lithium carbonate closed at 79,020 yuan/ton, a slight decline of 0.45% from the previous trading day. The basis continued to weaken, dropping from 3,320 yuan/ton on the 25th to 2,680 yuan/ton, and the futures discount to the spot increased, indicating that the market's expectation of future supply pressure has increased [1]. - The trading volume of the main contract shrank by 10.7% to 559,599 lots, and the open interest decreased by 19,171 lots. The trading activity of funds cooled down, and some long - positions left the market for risk - avoidance [1]. b. Analysis of Industrial Chain Supply - Demand and Inventory Changes - **Supply side**: There are both short - term disturbances and long - term adjustments. The suspension of CATL's Jiangxi Jianxiawo lithium mica mining area since August 10 has supported the spot market. However, the expansion projects of salt - lake lithium extraction are advancing, and the capacity utilization rate of lithium carbonate has increased by 2.49 percentage points week - on - week to 66.41%, so the overall supply has increased marginally. In July, the import volume of lithium carbonate decreased by 22% month - on - month to 13,845 tons, but Chile's exports to China increased by 33% month - on - month, and the seasonal recovery of overseas supply may ease the tight domestic resource situation [2]. - **Demand side**: The demand in the peak season remains resilient but has limited upward momentum. From August 1 to 17, the retail penetration rate of new energy passenger vehicles reached 58%, and the demand has improved marginally. The production of cathode materials has remained at a high level, but the prices of power - type lithium iron phosphate and ternary materials have declined slightly, and the downstream cost transfer is under pressure. The overall cell prices are stable, and only the square lithium iron phosphate cells have risen slightly by 0.62%. The rigid demand on the demand side still exists, but the momentum for new orders is insufficient [2]. - **Inventory and warehouse receipts**: The lithium carbonate inventory decreased by 713 tons week - on - week to 141,543 tons, with a destocking rate of 0.5%, indicating that the supply - demand tight - balance pattern continues. There is no significant change in warehouse receipts, and the low - inventory environment still supports the price bottom [2]. c. Market Summary - The short - term lithium carbonate market may fluctuate widely within the current range. The lithium carbonate futures may continue to fluctuate within the high - level range, and attention should be paid to the unexpected disturbances to the supply caused by the production reduction or suspension events of lithium mica smelters due to cost inversion [3]. 2. Industrial Chain Price Monitoring - On August 26, the main contract of lithium carbonate was 79,020 yuan/ton, a decrease of 0.45% from August 25. The basis was 2,680 yuan/ton, a decrease of 19.28% from the previous day. The open interest of the main contract decreased by 5.20% to 349,496 lots, and the trading volume decreased by 10.74% to 559,599 lots. The market price of battery - grade lithium carbonate was 81,700 yuan/ton, a decrease of 1.21% [5]. - From August 15 to August 22, the capacity utilization rate of lithium carbonate increased from 63.92% to 66.41%, and the inventory decreased by 0.50% to 141,543 tons. Among the cells, the price of 523 cylindrical ternary cells increased by 0.23%, the price of cobalt - acid lithium cells increased by 3.60%, and the price of square lithium iron phosphate cells increased by 0.62% [5]. 3. Industry Dynamics and Interpretations a. Spot Market Quotations - On August 26, the SMM battery - grade lithium carbonate index price was 81,739 yuan/ton, a decrease of 780 yuan/ton from the previous working day. The downstream procurement and pricing activities increased slightly compared with the previous day, but some manufacturers reduced their procurement volume this week compared with last week. The overall downstream procurement attitude has become cautious, and they are generally waiting for further price cuts. In the short term, the spot price of lithium carbonate is expected to remain relatively high and continue to fluctuate within the range [6]. b. Downstream Consumption Situation - From August 1 to 17, the retail volume of the new energy passenger vehicle market was 502,000 units, a year - on - year increase of 9% and a month - on - month increase of 12%. The retail penetration rate was 58.0%, and the cumulative retail volume this year was 6.958 million units, a year - on - year increase of 28%. The wholesale volume of new energy passenger vehicles was 474,000 units, a year - on - year increase of 18% and a month - on - month increase of 10%. The wholesale penetration rate was 56.4%, and the cumulative wholesale volume this year was 8.108 million units, a year - on - year increase of 34% [7]. c. Industry News - Since the official suspension of CATL's Jiangxi Yichun Jianxiawo mining area on August 10, the "butterfly effect" has spread throughout the industrial chain [8]. - On August 18, Lanxiao Technology won the bid for the adsorption system of the expansion and renovation project of the comprehensive utilization of old brine for lithium extraction from the Lop Nur Salt Lake of Guotou Xinjiang Lithium Industry Co., Ltd., with a bid amount of 35.7712 million yuan, which will have a positive impact on the company's development in the salt - lake lithium extraction industry [9]. - On August 15, CATL's Jianxiawo mining area suspended production due to the expiration of the mining license, which will directly affect the price of lithium carbonate. Yichun local mines are required to re - apply before September 30 this year [9]. 4. Industrial Chain Data Charts - The content mainly lists the names of various data charts, including the main contract and basis of lithium carbonate futures, lithium concentrate prices, etc., without specific data descriptions [10][13][15]
