1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints of the Report - The short - term oil price is likely to remain in a volatile pattern. The supply side has formed a new balance between the increase in US exports and India's oil source switch, but the expansion of Russian oil discounts may stimulate non - US buyers to replenish stocks. On the demand side, the high refinery operating rate coexists with the differentiation of terminal refined oil consumption. The reduction of gasoline inventory supports the oil price, while the concern of diesel inventory accumulation limits the upside space. In the medium term, attention should be paid to the continuity of OPEC+ production policy and the autumn maintenance rhythm of Northern Hemisphere refineries [5]. - The crude oil market presents a mixed situation of long and short factors. On the supply side, the increase in US exports, the resumption of the Friendship Pipeline, and India's procurement structure adjustment may increase market supply, but Norway's stable production and OPEC+ production cuts still support oil prices. On the demand side, the high operating rate of US refineries and the recovery of crude oil demand support consumption, but the high distillate oil inventory indicates weak diesel demand. Inventory depletion is good but shows regional differentiation. The increase in Cushing inventory suppresses WTI, while the decline in commercial inventory provides support. Geopolitical risks and changes in trade flows increase market uncertainty. International oil prices are expected to maintain a volatile pattern [66]. 3. Summary by Relevant Catalogs 3.1 Daily Market Summary 3.1.1 Crude Oil Futures Market Data Changes Analysis - On August 20, the SC crude oil main contract closed at 484.2 yuan/barrel, slightly down from the previous day. WTI and Brent closed at $62.0/barrel and $65.95/barrel respectively, continuing the weak consolidation. The SC - Brent spread widened to $1.47/barrel, and the SC - WTI spread widened to $5.42/barrel, indicating the continued valuation repair of domestic SC crude oil relative to international oil prices. The Brent - WTI spread rose to $3.95/barrel, and the tight supply pattern in the European market supported the Brent premium. The near - end contract of SC weakened, and the spread between consecutive 1 and consecutive 3 changed from +2.2 yuan/barrel the previous day to -3.7 yuan/barrel, showing the pressure of near - month delivery [2]. - The daily fluctuation range of the SC crude oil main contract narrowed to 481.9 - 488.1 yuan/barrel, and the closing price fell slightly by 0.87%, reflecting that the market trading sentiment tended to be cautious [2]. 3.1.2 Analysis of Industrial Chain Supply - Demand and Inventory Changes - **Supply side**: Norway's crude oil production in July remained at 1.958 million barrels per day, and the production of non - OPEC+ countries was stable. The crude oil supply of the Friendship Pipeline to Hungary and Slovakia resumed, and the Eurasian land logistics disturbance was alleviated. Indian state - owned refineries reduced their purchases of Russian oil (a 19% month - on - month decrease in July) and turned to Middle Eastern and US oil sources, and the Russian oil export structure faced adjustment pressure. US crude oil exports are expected to rebound to more than 4 million barrels per day in August and September, and the discount of WTI relative to Middle Eastern oil stimulates Asian demand [3]. - **Demand side**: The operating rate of US refineries rose to 96.6% (previous value 96.4%), the demand for crude oil processing strengthened, and the derived demand for crude oil production jumped to 20.738 million barrels per day (previous value 19.813 million barrels). The operating rate of Japanese refineries rose to 86.9% (previous value 84.4%), but the commercial crude oil inventory decreased by 27,777 kiloliters, and the replenishment of gasoline and kerosene was active. Diesel demand showed fatigue, and the derived demand for US distillate oil production slightly decreased to 5.1193 million barrels per day (previous value 5.142 million barrels) [3]. - **Inventory side**: US commercial crude oil inventories plummeted by 6.014 million barrels (expected to decrease by 1.759 million barrels). The larger - than - expected decline was mainly due to a large decrease in imports of 1.218 million barrels and an increase in derived demand for production. Cushing inventories increased by 0.419 million barrels against the trend (previous value +0.045 million barrels), and inventory accumulation at the delivery location suppressed WTI. EIA data showed a significant reduction in US crude oil inventories, but the increase in Cushing inventories and the differentiation of refined oil inventories limited the rebound momentum of oil prices. The differentiation of refined oil inventories was significant. Gasoline inventories decreased by 2.72 million barrels more than expected, and refined oil inventories increased significantly by 2.343 million barrels, indicating weak diesel demand and the support of gasoline consumption by the summer travel season [4]. 3.1.3 Price Trend Judgment The short - term oil price may still maintain a volatile pattern. On the supply side, the increase in US exports and the switch of Indian oil sources form a new balance, but the expansion of Russian oil discounts may stimulate non - US buyers to replenish stocks. On the demand side, the high operating rate of refineries coexists with the differentiation of terminal refined oil consumption. The reduction of gasoline inventory provides support for the oil price, while the concern of diesel inventory accumulation limits the upside space. In the medium term, pay attention to the continuity of OPEC+ production policy and the autumn maintenance rhythm of Northern Hemisphere refineries [5]. 3.2 Industrial Chain Price Monitoring 3.2.1 Crude Oil - **Futures prices**: On August 20, 2025, the SC futures price was 482.80 yuan/barrel, down 1.40 yuan or -0.29% from the previous day; the WTI futures price was $62.84/barrel, up $0.84 or 1.35%; the Brent futures price was $67.04/barrel, up $1.09 or 1.65% [7]. - **Spot prices**: The OPEC basket price remained unchanged at $68.45/barrel.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The supply - demand situation of pure benzene has marginally improved, but there are still contradictions between high - level hidden inventory and weak terminal consumption. The demand during the traditional peak season of "Golden September and Silver October" remains a key variable [3]. - The styrene market is generally loose, with new production capacity being continuously released. Although there are signs of marginal improvement, new production capacity and the weakening basis point to the problems of oversupply and difficulty in destocking [4]. 3. Summary by Related Catalogs 3.1 Daily Market Summary 3.1.1 Fundamentals - **Price**: On August 20, the styrene main contract closed up 0.82% at 7,285 yuan/ton, with a basis of - 10 (+54 yuan/ton); the pure benzene main contract closed up 0.37% at 6,205 yuan/ton [2]. - **Cost**: On August 20, Brent crude oil closed at 61.8 (-1.7 dollars/barrel), WTI crude oil closed at 65.8 (-0.8 dollars/barrel), and the spot price of pure benzene in East China was 6,070 yuan/ton (-35 yuan/ton) [2]. - **Inventory**: Styrene sample factory inventory was 20.9 tons (-0.3 tons), a 1.3% month - on - month destocking; Jiangsu port inventory was 14.9 tons (-1.0 tons), a 6.42% month - on - month destocking. Pure benzene port inventory was 14.6 tons (-1.7 tons), a 10.43% month - on - month destocking [2]. - **Supply**: A new styrene plant in Shandong was put into operation, and the overall supply remained stable. The weekly styrene output was 36.9 tons (+1.0 tons), and the factory capacity utilization rate was 78.2% (+0.5%) [2]. - **Demand**: The capacity utilization rates of downstream 3S varied. The EPS capacity utilization rate was 58.1% (+14.4%), the ABS capacity utilization rate was 71.1% (+0%), and the PS capacity utilization rate was 56.7% (+1.7%). The EPS operating rate recovered, and the ABS and PS operating rates continued to increase [2]. 3.1.2 Views - **Pure Benzene**: The supply side has been running strongly recently. The supply has increased, and the demand shows structural differentiation. Although the supply - demand balance has marginally improved, there are still problems such as high - level hidden inventory and weak terminal consumption [3]. - **Styrene**: The market is generally loose, with new production capacity continuously released. The demand improvement is limited, and the basis weakening reflects the intensification of supply - demand mismatch and weakening market sentiment [4]. 3.2 Industrial Chain Data Monitoring - **Styrene and Pure Benzene Prices**: The styrene futures main contract increased by 0.82%, the pure benzene futures main contract increased by 0.37%, and the styrene basis decreased by 118.52% [6]. - **Styrene and Pure Benzene Output and Inventory**: Styrene output increased by 2.76%, pure benzene output decreased by 0.18%. Styrene and pure benzene inventories decreased to varying degrees [7]. - **Operating Rate**: The capacity utilization rates of some downstream products of pure benzene and styrene increased, such as the EPS capacity utilization rate increased by 14.41% [8]. 3.3 Industry News - China's shale cracking raw material supply is affected by trade and production capacity, pushing up naphtha costs. China is expected to increase naphtha imports to a record high in 2025 [9]. - The global diesel shortage supports refinery profits, having a structural impact on the crude oil and chemical chains [9]. - India is accelerating petrochemical expansion to counter China's dominant position [9].

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The PTA price is expected to fluctuate weakly due to weak cost and cautious demand expectations. The supply of PX and PTA may increase due to high - device operation rates and new production capacities, while the demand lacks strong support, and inventory may accumulate, putting downward pressure on prices. However, seasonal changes in demand and device changes need to be monitored [1][38]. 3. Summary by Related Catalogs 3.1 Daily Market Summary 3.1.1 PTA & PX - On August 19, the PX主力contract closed at 6,774.0 yuan/ton, up 0.21% from the previous trading day, with a basis of - 165.0 yuan/ton. The PTA主力contract closed at 4,734.0 yuan/ton, down 0.25% from the previous trading day, with a basis of - 64.0 yuan/ton [2]. - The cost - end: On August 19, the Brent crude oil主力contract closed at 66.46 US dollars/barrel, and WTI at 62.58 US dollars/barrel. The demand - end: On August 19, the total transaction volume of the Light Textile City was 487.0 million meters, and the 15 - day average transaction was 485.47 million meters [2]. - Supply side: The operation rates of PX and PTA devices remain high, and with the gradual implementation of new production capacities, the pressure of increased industry supply may continue to be released. The cost - end drive of PX is weak under the background of low - level fluctuations in crude oil prices, and the processing fees of PTA are suppressed by over - capacity, and the willingness of factories to increase production may further exacerbate the supply - loosening situation [2]. - Demand side: The transactions in the Light Textile City maintain a weak and stable pattern. Although the downstream polyester operation rate has not weakened significantly, the fabric orders lack substantial improvement. The traditional textile peak season is approaching, but the demand has not shown a continuous improvement, and the terminal negative feedback pressure continues to be transmitted upstream, making it difficult for the PTA demand side to form effective support [2]. - Inventory side: The PTA factory inventory is restricted by the weak basis structure, and the social inventory continues to accumulate. Currently, there are not many active production - reduction actions by factories, and there is still pressure on the price ceiling [3]. 3.1.2 Polyester - On August 19, the short - fiber主力contract closed at 6,432.0 yuan/ton, down 0.46% from the previous trading day. The spot price in the East China market was 6,500.0 yuan/ton, up 20.0 yuan/ton from the previous trading day, with a basis of 68.0 yuan/ton [4]. - Supply side: The PX price has recently shown high - level fluctuations (ranging from 6,614 to 6,832 yuan/ton from August 11 - 19), but the PTA price has risen steadily (up 1.4% to 4,746 yuan/ton during the same period), indicating that the cost - end support is weakening but the downstream acceptance is good [4]. - Demand side: The 15 - day moving average transaction volume of the Light Textile City has continuously rebounded from 479 million meters to 485 million meters, reflecting the gradual recovery of terminal textile demand [4]. - Inventory side: There is a structural differentiation in inventory. The inventory days of polyester staple fiber (7.25 days) are significantly higher than the five - year average (4.96 days), while the inventory of polyester filament POY (16.1 days) is lower than the average (20.4 days), and the inventory of FDY/DTY is basically the same as the historical average. The high - inventory pressure of short - fiber may restrict the overall increase, and continue to pay attention to polyester production - reduction information [4]. 3.2 Industrial Chain Price Monitoring - PX futures: The主力contract price on August 19 was 6,774 yuan/ton, up 0.21% from the previous day; the成交volume increased by 68.14%, and the持仓volume increased by 6.83%.

It is still a good prediction to cut interest rates twice this year; Goolsbee said that the latest PPI and CPI inflation data were disturbing. If signs show that inflation is not in a spiral in September or later in the fall, interest rates can be cut. The market reduced its bets on interest - rate cuts but still expected a cut in September and another cut in 2025 [7]. - On August 18, Hong Kong's Financial Secretary Paul Chan said that the plan for Hong Kong to develop an international gold trading center would be announced within the year [7]. 3.3.2 Supply - Demand (Demand) - On August 19, the total transaction volume of the Light Textile City was 487.0 million meters, a month - on - month decrease of 4.32%, with the long - fiber fabric transaction volume at 393.0 million meters and the short - fiber fabric transaction volume at 93.0 million meters [8]. 3.4 Industrial Chain Data Charts The report provides multiple data charts, including PX and PTA主力futures and basis, PX and PTA spot prices, PX capacity utilization, PTA futures monthly spreads, PTA processing profits, industrial chain load rates, polyester short - fiber and long - fiber sales situations, Light Textile City transaction volume moving average, and polyester product inventory days [9][11][13].

Report Overview - Report Title: Supply and Demand Improve, but the Actual Magnitude is Limited. Lithium Carbonate is Difficult to Maintain Long - Term and Significant Increases - Lithium Carbonate Industry Chain Weekly Data Report [1] - Report Date: August 20, 2025 [1] 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - The shutdown of the Jianxiawo Mine has brought lithium carbonate prices to a new level, and the marginal change from passive inventory accumulation to passive inventory depletion in lithium carbonate supply and demand has significantly improved the market expectations in the first half of the year, with the price center expected to rise. However, the expected annual inventory depletion of 1 - 2 million tons after the shutdown is limited compared to the current market inventory of 14 million tons. If the market continues to rise significantly, it may open the profit window for imported lithium mines such as those from Australia and Africa, quickly making up for the supply reduction caused by the shutdown of the Jianxiawo Mine and attracting hedging funds, so it may experience short - term significant increases but is difficult to maintain in the long term [4]. 3. Summary by Directory 3.1 Weekly Report Summary 3.1.1 Fundamental Overview - Lithium Ore: The price of spodumene has risen rapidly, leading the increase in ore prices. Affected by administrative orders in Jiangxi and Qinghai, the operating rates of lithium mica and salt lake sectors have significantly declined in July. After the confirmation of the shutdown of Jianxiawo, the market demand for lithium mica has significantly decreased, and the price of spodumene, as an alternative, has led the increase in the lithium ore market. Attention should be paid to the quantity of imported spodumene supplemented due to high prices [3]. - Lithium Salt: It has continued to take advantage of the situation, and the upper integer price levels may be the targets of long - positions. The news of the shutdown of Jianxiawo last week pushed the lithium carbonate LC futures contract to the price range of 80,000 yuan. The marginal reduction may change the domestic lithium carbonate supply - demand from passive inventory accumulation to passive inventory depletion. The market long - positions continue to take advantage of the market rumors of the shutdown of the salt lake sector to drive up prices, with the upper levels of 90,000 and 100,000 yuan being the next targets of long - positions. However, with a high inventory of 14 million tons, it is difficult for lithium carbonate to maintain high prices in the long term [3]. - Cathode Materials and Lithium Batteries: The impact of anti - involution is gradually fading. The impact of anti - involution focused on the new energy vehicle market is gradually fading. Recently, lithium carbonate has been indirectly affected by the sentiment of industries such as photovoltaics, with limited substantial impact [3]. 3.1.2 Market Summary - The shutdown of the Jianxiawo Mine has brought lithium carbonate prices to a new level. The marginal change in supply and demand has improved market expectations, but the expected inventory depletion is limited compared to the current inventory. If the market rises significantly, it may attract imported lithium mines and hedging funds, making it difficult to maintain long - term high prices [4]. 3.2 Supply - Demand Balance Sheet 3.2.1 Lithium Carbonate Balance Sheet - Slowing Inventory Accumulation - From July 2024 to July 2025, the supply, demand, import, export, inventory change, and cumulative balance of lithium carbonate showed different trends.
