1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Polyester Industry - PX: Short - term supply is stable, but 8 - month downstream PTA device maintenance increases and terminal demand lacks improvement. Its trend follows macro - sentiment and oil prices. PX09 is treated with caution and short - bias, and the PX - SC spread is expanded at low levels [2]. - PTA: Current load is around 80%, but 8 - month device maintenance increases. Supply - demand improves in the short - term but weakens in the medium - term. The absolute price follows the cost and market sentiment. TA is short - biased above 4900, TA9 - 1 is in a rolling reverse spread operation, and the PTA disk processing fee is expanded at low levels [2]. - Ethylene Glycol: Supply turns loose in August, and demand is weak in the traditional off - season. It is greatly affected by the macro in the short - term. EGO9 is on the sidelines, and 9 - 1 is in a reverse spread operation [2]. - Short - fiber: Supply - demand is weak in the short - term, and the absolute price follows the raw materials. The operation strategy is the same as TA, and the PF disk processing fee fluctuates between 800 - 1100 [2]. - Bottle - chip: Supply is high, demand follows up generally, and the processing fee increase is limited. The absolute price follows the cost. PR is the same as PTA, and the PR main disk processing fee is expected to fluctuate between 350 - 600 yuan/ton [2]. Urea Industry The core contradiction of the urea fundamentals is unresolved, and the market is in a shock pattern. It is recommended to use a band - trading idea, and the release of export demand needs to be tracked [10]. Crude Oil Industry Overnight oil prices rose, driven by macro and geopolitical factors. In the short - term, the upward momentum of prices depends on the continuation of geopolitical tensions. It is recommended to use a band - trading idea, with short - term long - bias [55]. PVC and Caustic Soda Industry - Caustic Soda: The disk is volatile and relatively resistant to decline. Spot prices are stable for now, and it is expected that the liquid caustic soda price will be stable this week. Attention should be paid to risk avoidance [43]. - PVC: The disk is volatile and relatively resistant to decline. Spot prices are rising, and export expectations are good. However, the overall supply exceeds demand, and short - term caution is recommended [43]. Pure Benzene and Styrene Industry - Pure Benzene: Supply - demand improves slightly in the first quarter, but the destocking amplitude is limited. It follows the overall market sentiment in the short - term, and the main contract BZ2603 follows the oil price and styrene [46]. - Styrene: Supply - demand is expected to be weak, and the basis is weakening. The price is under pressure, and EB09 is in a rolling short - bias operation [46]. LLDPE and PP Industry In August, the supply pressure of PP and PE increases, and there is potential restocking demand. The overall valuation is moderately high, and the fundamental contradiction is not significant. PP is short - biased (7200 - 7300), and LP01 is held [50]. Methanol Industry Inland maintenance will peak in early August, production is high, ports are slightly accumulating inventory, and the basis is weakening. In August, imports are still high, and downstream demand is weak. The MTO09 profit can be expanded at low levels [58]. 3.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Polyolefin Industry - The valuation shows that the marginal profit is gradually recovering, and the supply and demand of PP and PE are simultaneously contracting, with inventory accumulation. The demand side continues to be in a weak state. There is a risk of capacity withdrawal for devices with a production history of over 20 years. Strategy-wise, there is an opportunity for PP to fluctuate on the short - side, and PE can be bought within a certain range [2]. Crude Oil Industry - Overnight oil prices rose due to the repair of market demand expectations after the alleviation of macro - tense emotions. However, the OPEC+ production increase plan and Sino - US trade uncertainties pose upward resistance. It is recommended to adopt a short - term band strategy [5]. Pure Benzene and Styrene Industry - Pure benzene's previous maintenance devices are gradually restarting, and its downstream price transmission is not smooth. The short - term trend of pure benzene fluctuates with the overall market sentiment. Styrene's supply - demand expectation is weak, but it is supported in the short - term by the domestic anti - involution sentiment, with limited upside [44]. Methanol Industry - Inland methanol prices fluctuate slightly. The supply side has high maintenance losses in July but there is a restart expectation. The demand side is restricted by the traditional off - season. The port side is expected to accumulate inventory from July to August. In the short - term, the cost is lifted by coal, and the 09 contract's fluctuation range moves up. It is advisable to buy the 01 contract at low prices [47]. Chlor - alkali Industry - For caustic soda, the short - term macro - disturbance is intense, and it is recommended to close previous long positions and wait and see. For PVC, the short - term trading logic is mainly dominated by macro - emotions, and it is recommended to wait and see [52]. Polyester Industry Chain - PX is expected to fluctuate strongly in the short - term. PTA may fluctuate strongly in the short - term. Ethylene glycol is expected to run strongly in the short - term. Short - fiber has no obvious short - term driver. Bottle - chip supply - demand has an improvement expectation [71]. Urea Industry - The urea futures market is in a range - bound pattern. The supply is sufficient, and the demand is weak, resulting in a supply - exceeding - demand situation. The future price breakthrough depends on the substantial warming of the demand side [78]. 3. Summaries by Related Catalogs Polyolefin Industry - **Prices**: Futures and spot prices of L and PP increased on July 24 compared to July 23.

1. Report Industry Investment Rating - Unilateral: Neutral; - Inter - period: PL01 - 05 reverse spread; - Inter - variety: Long PL2601 and short PP2509 [4] 2. Core Viewpoints - Macro policies such as anti - involution and elimination of backward production capacity continue to boost the propylene and polyolefin markets. The elimination of backward production capacity in the propylene industry is expected to shift the domestic propylene market from an oversupply to a tight - balance situation. However, the current overall propylene operating rate is at a seasonally low level, and downstream demand has limited driving force. For polyolefins, although macro policies boost the market, the cost - side support is weak, and downstream demand remains weak during the seasonal off - season [3] 3. Summary by Relevant Catalogs 3.1 Propylene 3.1.1 Propylene Basis Structure - It includes the market prices of propylene in East China and Shandong [10][12] 3.1.2 Propylene Production Profit and Operating Rate - Involves the difference between propylene CFR in China and naphtha CFR in Japan, propylene capacity utilization rate, PDH production gross profit and capacity utilization rate, MTO production gross profit, and methanol - to - olefin capacity utilization rate [13][18][22] 3.1.3 Propylene Import and Export Profit - Covers propylene naphtha cracking production gross profit, crude oil refinery capacity utilization rate, and the differences between FOB in South Korea, CFR in Japan, and CFR in Southeast Asia and China CFR, as well as propylene import profit [25][28][33] 3.1.4 Propylene Downstream Profit and Operating Rate - Includes the production profit and operating rate of PP powder, propylene oxide, n - butanol, octanol, acrylic acid, acrylonitrile, and phenol - acetone [35][40][42] 3.1.5 Propylene Inventory - Comprises propylene factory inventory and PP powder factory inventory [59][61] 3.2 Polyolefins 3.2.1 Polyolefin Basis Structure - Involves the trends of plastic and polypropylene futures main contracts, and the basis between LL in East China and the main contract, and PP in East China and the main contract [63][64][70] 3.2.2 Polyolefin Production Profit and Operating Rate - Covers LL production profit from crude oil, PE operating rate, PE weekly output, PE maintenance loss, PP production profit from crude oil and PDH, PP operating rate, PP weekly output, PP maintenance loss, and PDH - made PP capacity utilization rate [71][72][77] 3.2.3 Polyolefin Non - Standard Price Difference - Includes the price differences between HD injection molding, HD blow molding, HD film, LD in East China and LL, and the price differences between PP low - melt copolymer and PP homopolymer injection molding and PP drawing in East China [84][91][92] 3.2.4 Polyolefin Import and Export Profit - Involves LL import profit, the differences between FOB in the US Gulf, CFR in Southeast Asia, FD in Europe and China CFR, PP import and export profit, and the differences between FOB in the US Gulf, CFR in Southeast Asia, FOB in Northwest Europe of PP homopolymer injection molding and China CFR [93][97][109] 3.2.5 Polyolefin Downstream Operating Rate and Profit - Includes the operating rates of PE downstream agricultural film, packaging film, and PP downstream woven bags, BOPP film, injection molding, and the production gross profits of PP downstream woven bags and BOPP film [117][120][127] 3.2.6 Polyolefin Inventory - Comprises the inventories of PE and PP in oil - based enterprises, coal - chemical enterprises, traders, and ports [133][134][136]

1. Report Industry Investment Ratings - Not provided in the given content 2. Core Views Polyolefin Industry - Valuation shows marginal profit gradually recovering, with synchronized contraction in PP and PE supply - demand, inventory accumulation, and a weak demand trend. PP maintenance has peaked, while PE maintenance first rises then falls. There are few import offers, and some Middle - East devices are shut down due to power issues. There will be a seasonal recovery in demand at the end of July. There is a risk of capacity withdrawal for devices over 20 years old. Strategy: unilateral short - term opportunity for PP with a bearish bias, and range - bound buying for PE [2] Methanol Industry - Inland prices fluctuate slightly. Supply has high maintenance losses in July but with expected复产. Demand is restricted by the traditional off - season of downstream industries, and new capacity launch affects the market. At the port, the basis strengthens. Overseas Iranian device production is back, with expected imports of 125 million tons in July and a slight decline in August. After MTO profit repair, maintenance is uncertain. There will be inventory accumulation from July to August, and prices are weak [5] Pure Benzene - Styrene Industry - The supply - demand outlook for pure benzene improves in July. Although there are production news releases, the impact on loss volume is limited. Downstream price transmission is poor except for styrene. With high import expectations and high port inventory, its own driving force is limited. However, it may be boosted in the short - term, but the rebound space is limited. For styrene, the industry profit is maintained, and the operating rate is high. The supply - demand margin is repaired, but the supply - demand outlook is weak, and port inventory increases. It is boosted in the short - term but has limited upside [7] Polyester Industry Chain - In July, the PX supply - demand is good overall. Although some factory loads fluctuate, the overall supply impact is limited. Downstream PTA has increased maintenance expectations after significant processing fee compression, and terminal demand feedback is negative. PX demand support is weak. Considering new PTA capacity, the PX supply - demand outlook is tight, and PXN has some support. It may be boosted in the short - term but is restricted by demand and oil price expectations. For PTA, the load is around 80%, and with new device expectations and weak terminal demand, the supply - demand outlook is weak. It may be supported in the short - term by market sentiment. For other products like MEG, short - fiber, and bottle - chip, their supply - demand and price trends are analyzed respectively [11] Crude Oil Industry - Overnight oil prices fluctuated weakly. The upper pressure comes from US tariff threats and EU sanctions on Russia, while the lower support is from the diesel fundamentals. Diesel cracking profit in Europe reaches a high level since 2024, indicating a tight medium - heavy crude oil structure. Refinery high - operating rates lead to counter - seasonal diesel inventory drawdown. Oil prices show a wide - range oscillation pattern, and the short - term direction depends on sanctions' impact on Russian supply and tariff risks [32] Chlor - Alkali Industry - For caustic soda, the futures price is boosted by policies, and there is an expectation of industry capacity reduction. The spot trading is average, and the price in Guangdong drops. Low - grade caustic soda has low inventory due to alumina demand, but non - aluminum downstream resists high prices. The supply - demand contradiction is limited, and there is an upward price expectation in the peak season. For PVC, the futures price is also boosted by policies, but the spot market has little change. The supply - demand is in an off - season with increasing supply and decreasing demand, and the inventory slightly accumulates. Short - term trading is mainly driven by macro - sentiment [36][37] Urea Industry - The core driver of the urea futures is macro - policy. The Ministry of Industry and Information Technology's policies are interpreted as beneficial for the urea industry, which may reduce large - particle supply. Although export data shows weakness, policy news boosts market sentiment. The futures price rise stimulates spot trading, and the basis has a repair expectation. In the short - term, the capacity reduction probability is low, but in the long - term, there may be a transformation in urea production capacity structure. The market should focus on export quota execution and trading expectations [41][42] 3. Summary by Related Catalogs Polyolefin Industry - **Prices**: Futures and spot prices of L and PP increased on July 21 compared to July 18, with varying increase rates. The basis and price differences between different contracts also changed [2] - **Supply and Demand**: PE and PP device operating rates decreased slightly, and downstream operating rates also showed a downward trend. Inventories of PE and PP increased [2] Methanol Industry - **Prices**: Futures and spot prices of methanol changed slightly. The basis strengthened at the port, and regional price differences also had some changes [5] - **Supply and Demand**: Supply in July had high maintenance losses but with expected复产. Demand was restricted by the off - season. At the port, imports were expected to increase in July and decrease slightly in August, and there would be inventory accumulation from July to August [5] Pure Benzene - Styrene Industry - **Prices**: Prices of pure benzene, styrene, and related products increased on July 21 compared to July 18, and the cash - flow and price differences also changed [7] - **Supply and Demand**: The supply - demand outlook for pure benzene improved in July, but downstream price transmission was poor. For styrene, the industry profit was maintained, and the operating rate was high, but the supply - demand outlook was weak [7] Polyester Industry Chain - **Prices**: Prices of upstream raw materials such as oil, PX, and downstream polyester products changed slightly on July 21 compared to July 18. Processing fees and price differences also had corresponding changes [11] - **Supply and Demand**: PX supply - demand was good overall, but downstream PTA had increased maintenance expectations. For other products like MEG, short - fiber, and bottle - chip, their supply - demand situations were analyzed respectively [11] Crude Oil Industry - **Prices**: Brent, WTI, and SC oil prices decreased slightly on July 22 compared to July 21. Price differences between different contracts and between different oil types also changed [32] - **Supply and Demand**: The upper pressure on oil prices came from macro - factors, while the lower support was from diesel fundamentals. Diesel inventory showed counter - seasonal drawdown [32] Chlor - Alkali Industry - **Prices**: Prices of caustic soda and PVC futures and spot products changed on July 21 compared to July 18, and the basis and price differences also had corresponding changes [36] - **Supply and Demand**: For caustic soda, the supply - demand contradiction was limited, and for PVC, it was in an off - season with increasing supply and decreasing demand [36][37] Urea Industry - **Prices**: Spot prices of urea in different regions increased slightly on July 21 compared to July 18. The basis and price differences also changed [40] - **Supply and Demand**: Domestic urea daily and weekly production decreased slightly, and the plant - level inventory decreased, while the port inventory increased [41]

1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating in the given content. 2. Core Views Methanol - The inland market's maintenance has reached its peak, and there is an expectation of increased production in late July. The port market faces dual pressures: an expected arrival of 1.25 million tons in July and planned maintenance of coastal MTO units, which will weaken demand. The port will continue to accumulate inventory from July to August, but the current absolute inventory is relatively low year - on - year, with limited upside and downside space, suggesting range - bound operations [4]. Crude Oil - Overnight oil prices fluctuated weakly. The main logic is the weakening downstream market and the approaching end of the consumption peak season, with a possible supply surplus in the second half of the year. The EIA weekly report shows that Cushing inventory reached its highest level since June, and US distillate demand slightly declined, although crude oil inventory decreased by 3.86 million barrels. In the short term, after the oil price decline, there is a high probability of a stalemate between bulls and bears. It is recommended to adopt a short - term band strategy [27]. Polyester Industry Chain - **PX**: Short - term downward pressure exists due to factors such as the postponement of some domestic device maintenance plans and the recovery of overseas supply. However, considering the expected commissioning of new PTA devices, the supply - demand situation is expected to remain tight, and there is support at low levels [31]. - **PTA**: The supply - demand situation is expected to be weak, with a weakening basis. The absolute price is under pressure. Strategies include range - bound operations, short - selling above 4800, and other operations [31]. - **Ethylene Glycol**: The price is expected to fluctuate and consolidate in the short term. It is recommended to wait and see for the EGO9 contract and pay attention to the pressure around 4400 [31]. - **Short Fiber**: The supply - demand situation is weak on both sides, with limited driving forces. The absolute price fluctuates with raw materials [31]. - **Bottle Chips**: There is an expectation of improved supply - demand, but the absolute price still follows the cost side. Attention should be paid to further production cuts and downstream follow - up [31]. Polyolefins - From a supply - demand perspective, PP maintenance is gradually peaking, and PE maintenance in the second half of the month is still relatively high. It is the seasonal off - season for demand, with static supply and demand both declining, inventory accumulating, and apparent demand weakening. Dynamically, PE import offers are still scarce, and demand is expected to improve seasonally in late July. For unilateral strategies, both PP and PE lack strong driving forces, and range - bound operations are recommended. For arbitrage, take profit when LP is around 250 [35]. Urea - The futures price has recently declined. The short - term driving forces for the futures price mainly come from the seasonal weakening of demand and the increasing supply pressure, with export expectations providing partial support for large - granular urea. Agricultural demand has ended, leading to a decline in the spot trading atmosphere, which in turn drags down the futures sentiment. The supply side has a high daily output, and although maintenance has increased, the total supply is abundant, and the weak new order transactions amplify the pessimistic atmosphere. Exports only support large - granular urea locally and have limited impact on small - granular urea. It is expected that the futures price may still face pressure in the short term [42]. Pure Benzene and Styrene - **Pure Benzene**: The supply - demand situation is expected to improve in July, but due to high import expectations and relatively high port inventory, its own driving force is limited. Affected by weak oil prices and the styrene price, it may fluctuate weakly in the short term. It is recommended to wait and see for the main contract BZ2603 and adopt a reverse spread strategy for the monthly spread [46]. - **Styrene**: The supply - demand situation is expected to be weak, with increasing port inventory and short - term pressure on the basis. It is under short - term pressure. Strategies include short - selling the EB08 contract, selling call options with an exercise price above 7500, and narrowing the EB - BZ spread [46]. 3. Summary by Relevant Catalogs Methanol - **Prices and Spreads**: On July 16, MA2601 closed at 2434, MA2509 at 2367, with a MA91 spread of - 67 and a Taicang basis of 11.

1. Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2. Core Viewpoints of the Report - BZ futures discount has narrowed, and the strong downstream demand for BZ has led to a decline in pure benzene port inventory from a high level. The high operating rates of downstream styrene and CPL support the demand, and the increase in polymer MDI operating rate drives up the aniline operating rate. However, the sustainability of CPL's high operating rate is still questionable due to the decline in PA6 and nylon filament operating rates. On the supply side, the pressure of South Korea's exports to China remains, and domestic production operating rates are still high, resulting in the continued weak consolidation of pure benzene processing fees. For styrene, port inventory has further increased, and the EB basis has rapidly declined. Domestically, EB maintains a high operating rate on the supply side, while on the demand side, the operating rates of EPS and PS drag down EB demand [3]. 3. Summary According to the Directory I. Pure Benzene and EB's Basis Structure, Inter - Period Spreads - The report mentions various basis and spread data of pure benzene and EB, including pure benzene's main basis, the spread between pure benzene spot and M2 paper goods, the spread between the first - and third - continuous contracts of pure benzene, EB's main contract basis, and the spread between the first - and third - continuous contracts of styrene [1][13][19].

1. Report Industry Investment Rating No information provided in the content. 2. Report's Core Viewpoints - Urea: The recent decline in the futures market is due to weak domestic demand, with summer agricultural demand weakening and industrial demand affected by high temperatures. Although export quotas are being implemented, the second - batch quota has not circulated, so the domestic supply - demand imbalance persists, and the futures market may face pressure in the short term [6]. - Methanol: The inland market's maintenance has peaked, and production is expected to increase in late July. The port market faces dual pressures, with expected arrivals of 125 million tons in July and planned maintenance of coastal MTO, which will reduce ethylene demand. It is expected that the port will experience a slight inventory build - up in July, but the absolute inventory is low, with limited upside and downside, suggesting interval operations [9]. - Pure Benzene and Styrene: In July, the supply - demand outlook for pure benzene is improving, but high import expectations and high port inventories limit its upward momentum. Downstream price transmission is poor, restricting its rebound. It may fluctuate weakly in the short term. For styrene, high industry profits have led to high - level operations, but some downstream losses and high finished - product inventories have led to production cuts. Supply - demand is expected to weaken, and short - term basis may face pressure [11]. - PVC and Caustic Soda: The caustic soda spot market is generally stable, with some downstream demand support. There is an upward price expectation in the peak season. The PVC market has shown signs of a pull - back after a rise. The supply - demand pattern is in a off - season of increasing supply and decreasing demand, with weak procurement enthusiasm. It is recommended to wait and see [20]. - Crude Oil: Overnight oil prices fluctuated within a range. The macro - risk has eased, and the short - term supply concern has dissipated. Although China's refinery operating rate has reached a 10 - month high, it is overshadowed by macro - negatives. Short - term band strategies are recommended, and options can capture opportunities from increased volatility [24]. - Polyolefins (LLDPE and PP): Both PP and PE show a supply contraction, with compressed weighted profits and marginal profit repair. Static supply and demand are both decreasing, with inventory accumulation and weak apparent demand. In July, the supply pressure is not significant, and inventory reduction has improved. Unilateral strategies suggest interval operations, and LP250 can be taken as a profit - taking point for arbitrage [43]. - Polyester Industry Chain: For PX, the supply - demand is expected to remain tight, but the upward rebound is under pressure. For PTA, the supply - demand is expected to be weak, and the absolute price rebound is limited. For ethylene glycol, the supply - demand is turning to be loose, and the price is expected to fluctuate. For short - fiber, the supply - demand is weak, and the processing fee repair space is limited. For bottle - chips, the supply - demand has an improvement expectation, but the absolute price follows the cost [47]. 3.

Report Industry Investment Rating - Not provided in the content Core Viewpoints - BZ futures maintain a large premium, reflecting the contango structure of high - inventory pricing. The strong downstream demand for pure benzene has led to a decline in pure benzene port inventory from its high level. However, the supply pressure from South Korea's exports to China and high domestic production have kept the pure benzene processing fee in a weak consolidation. For styrene, the port inventory has further increased, and the EB basis has further declined. Domestic EB maintains high - level production, while the demand is dragged down by the low operation rates of EPS and PS [3]. Summary by Catalog 1.
