Report Industry Investment Rating No relevant content provided. Core Viewpoints - Urea futures showed a weak and volatile trend, mainly due to the game between the expected support from the export end and the domestic demand in the third quarter. The implementation of India's tender and the release of quotas will relieve the domestic high - supply pressure to some extent, but the domestic consumption restricts the upward elasticity. The short - term trend is likely to remain weak and volatile, and the actual export volume needs to be monitored [29]. - For methanol, the inland maintenance is expected to peak in early August, with high output year - on - year. The port has significantly accumulated inventory this week, and the import in August is still high. The downstream demand is weak due to low profits. The 09 contract has a strong expectation of inventory accumulation, while the 01 contract has seasonal peak season and Iran's shutdown expectations. It is recommended to build positions at low levels after the near - end weakens [32]. - In the polyester industry, the supply of PX is expected to increase marginally in August, but the demand from PTA and the terminal is not good, so the PX rebound is lack of drive. PTA's supply - demand situation has improved in the short - term but is expected to be weak in the medium - term. Ethylene glycol's short - term supply - demand is expected to improve. Short - fiber's short - term supply - demand drive is limited. Bottle - chip's processing fee has support, and its absolute price follows the cost [37]. - For PVC and caustic soda, the demand for caustic soda is currently good, but the supply is expected to increase in the future, and the rebound height is limited. PVC's supply pressure is increasing due to new capacity release, and the downstream demand has no sign of improvement [46]. - In the polyolefin industry, the supply of PP and PE has different trends, and the demand is expected to improve with the approaching of the peak season. The fundamental contradiction is not significant. It is recommended to stop profit for short positions and hold the LP01 contract [52]. - For crude oil, the overnight oil price declined due to the supply - side factors. The market sentiment is pessimistic, and the oil price is under pressure. The oil price is likely to remain weak, and the impact of the US - Russia negotiation on Friday needs to be monitored [59]. - In the pure benzene - styrene industry, pure benzene has short - term support but limited self - drive, and its rebound is under pressure. Styrene has a short - term situation of weak supply and demand, and it is expected to maintain a volatile trend [63].

Although the maintenance loss of PP was still at a high level, as the previously shut - down plants were gradually restarted and there were not many newly added maintenance plants, the impact of maintenance decreased. With the approaching of the 900,000 - ton/year capacity expansion plan of Ningbo Daxie Phase II, the incremental pressure on the supply side gradually emerged. For PE, the commissioning of Jilin Petrochemical at the end of July further expanded the production capacity base, and attention was paid to the new capacity addition of ExxonMobil Huizhou in August [6] - Demand: Downstream factories were still affected by the off - season. Coupled with the pressure of losses, the willingness to stock up was low. It was expected that the demand would gradually get out of the off - season in the second half of the month, but currently, downstream enterprises mostly maintained a low - inventory strategy [6] - Cost: The coal price was likely to rise due to coal mine production inspections and the peak summer coal - using season. The oil price might fall again due to the negative impact of OPEC+ production increase and the under - expected performance in the peak season [6] - Outlook: The loose fundamental pattern would continue to restrict the upward space. With the continuous release of new production capacity and the expected stocking demand driven by the "Golden September" peak season in the second half of the month, the polyolefin price might show a trend of bottom - building and then rebounding [6] Group 4: Industry News - Inventory: On August 13, 2025, the inventory level of major producers was 795,000 tons, a decrease of 20,000 tons (-2.45%) from the previous working day. The inventory at the same time last year was 815,000 tons [7] - PE Market: The PE market prices showed mixed trends. The linear futures opened lower and fluctuated, and the market trading atmosphere changed little. Traders reported prices with narrow fluctuations. The LDPE prices were firm, and downstream buyers purchased according to orders. The LLDPE prices in North China were 7200 - 7420 yuan/ton, in East China were 7240 - 7700 yuan/ton, and in South China were 7380 - 7700 yuan/ton [7] Group 5: Data Overview - Propylene Market: The mainstream price of propylene in the Shandong market was temporarily referred to as 6500 - 6530 yuan/ton. The profit margins of downstream products were compressed, and the willingness to accept propylene prices decreased. The demand support for propylene weakened. Production enterprises mostly offered small discounts to promote transactions, and the overall market trading atmosphere was average [13] - PP Market: The PP market was mainly adjusted narrowly. The mainstream prices of North China drawn wire were 6930 - 7090 yuan/ton, in East China were 7000 - 7140 yuan/ton, and in South China were 6950 - 7150 yuan/ton [13]

Core View of the Report The report believes that although the geopolitical premium has completely dissipated and the macro - environment is bearish, the current oil price is relatively undervalued, and its static fundamentals and dynamic forecasts are still good. It is a good opportunity for left - side layout, and the fundamentals will support the current price. If the geopolitical premium re - opens, the oil price will have more upside potential [2].

Core Views of the Report - The olefin - polyolefin market has mixed trends. Propylene has inventory and supply - side support, while polyolefin has limited upward drivers [2] - The pure benzene - styrene market shows different situations. Pure benzene has a slight recovery, and styrene has limited upward drivers due to cost and supply - demand contradictions [3] - The polyester industry has a slight upward shift in the center of gravity. Different products have different supply - demand and cost situations, and attention should be paid to oil price trends and demand recovery [4] - The coal - chemical industry has different trends in different regions for methanol, and urea is in the off - season with limited demand promotion [5] - The chlor - alkali industry has PVC with supply pressure and a weakening trend, and caustic soda with short - term supply reduction but long - term pressure [6] - The soda - glass industry has soda with emotional - driven short - term fluctuations and long - term supply pressure, and glass with cost support and attention to low - buying opportunities [7] 3. Summaries According to Relevant Catalogs 3.1 Olefin - Polyolefin - Propylene futures opened higher and fluctuated widely. Enterprises' low inventory and shutdown benefits boosted prices. Downstream demand was mainly rigid [2] - Polyolefin futures fluctuated narrowly. Polyethylene supply changed little, and demand increased slightly. Polypropylene supply increased slightly due to new capacity, and demand was weak [2] 3.2 Pure Benzene - Styrene - Pure benzene futures prices recovered with the increase of domestic production, decrease of imports, and port de - stocking. It was suggested to conduct monthly spread band operations [3] - Styrene futures closed up, but cost support was weak, and supply - demand contradictions still existed, with limited upward drivers [3] 3.3 Polyester - The polyester industry chain moved up slightly. PTA supply - demand was weak, PX had a positive outlook in the third quarter, and attention should be paid to oil price and demand [4] - Ethylene glycol prices rebounded slightly, with increasing industry start - up and expected demand recovery. Medium - term attention was on demand [4] - Short fiber supply - demand was stable, and it was suggested to be long - allocated in the medium - term. Bottle chip orders improved, but capacity over - supply was a long - term pressure [4] 3.4 Coal - chemical - Methanol fluctuated narrowly. Coal price increase compressed profits in the northwest, and there were differences between inland and port supply - demand situations. Attention was on downstream demand [5] - Urea was in the agricultural off - season, with increasing compound fertilizer start - up but limited demand promotion. It was expected to fluctuate in a range [5] 3.5 Chlor - alkali - PVC had supply pressure and was expected to have a weakening trend. Caustic soda had short - term supply reduction but long - term supply pressure [6] 3.6 Soda - Glass - Soda was affected by environmental news, with emotional - driven short - term fluctuations and long - term supply pressure [7] - Glass had cost support, and it was suggested to consider low - buying near the cost [7]

1. Report Industry Investment Rating The report does not provide an overall industry investment rating. However, for each individual energy and chemical product, the following ratings are given: - Crude oil: Volatile [1] - Fuel oil: Volatile [2] - Asphalt: Volatile [2] - Polyester: Volatile [2] - PX: Volatile [4] - Rubber: Volatile [4] - Methanol: Volatile [6] - Polyolefins: Volatile [6] - PVC: Volatile and slightly bearish [7] 2. Core Viewpoints of the Report - **Crude oil**: On Monday, oil prices stopped falling. OPEC+ crude oil production decreased in July. The market is waiting for the meeting between Trump and Putin, which may ease sanctions on Russian oil. However, there is still uncertainty in the market, and oil prices need to fluctuate and consolidate in the short term [1]. - **Fuel oil**: The main contracts of high - and low - sulfur fuel oil fell on Monday. Supply is sufficient, and the demand for high - sulfur fuel oil for power generation in summer is weakening. The upward space for high - and low - sulfur fuel oil is not optimistic [2]. - **Asphalt**: The main asphalt contract fell on Monday. Supply is expected to increase, and demand is expected to recover as the weather improves. The asphalt market in August is expected to show a pattern of increasing supply and demand, with prices fluctuating in a range [2]. - **Polyester**: The prices of PTA, EG, and PX futures rose on Monday. The supply of PTA and EG is recovering, and the downstream demand is in the off - season. It is expected that the spot prices of PTA and EG will fluctuate in the short term [2][4]. - **PX**: The supply and demand of PX continue to recover, and the PXN is slightly strong. PX prices are expected to follow the fluctuations of crude oil prices [4]. - **Rubber**: The prices of rubber futures rose on Monday. Short - term rubber raw materials are firm, demand expectations are improving, and inventories are stable. Rubber prices are expected to fluctuate strongly in the short term, but the medium - and long - term situation needs further attention [4]. - **Methanol**: The load of Iranian methanol plants has recovered, and port inventories have increased rapidly, suppressing near - month prices. However, the main contract will switch to January, and the downward space is limited. Methanol prices are expected to maintain a near - weak and far - strong structure and fluctuate narrowly [6]. - **Polyolefins**: The检修 season is coming to an end, and supply will remain high. With the approaching of the peak demand season, demand is expected to increase. Polyolefin prices are expected to fluctuate narrowly [6]. - **PVC**: Supply remains high, demand is gradually picking up, and inventories are expected to decline slowly. The basis and monthly spread have widened, and the market's short - selling power may recover. PVC prices are expected to fluctuate weakly [7]. 3.
