Report Investment Ratings No investment ratings for the industries are provided in the reports. Core Views - **Urea**: The current core driver of the futures market is the strong expectation of the substantial relaxation of export policies, which has been realized. China may resume urea exports to India, opening up an incremental market window. The policy window requires concentrated exports by the end of September, which coincides with the domestic autumn storage period, creating a demand resonance. The overall market is expected to oscillate strongly in the short term [1]. - **Polyester Industry Chain**: For PX, domestic supply is expected to increase as some maintenance devices gradually restart, and the absolute price rebound space is limited. PTA's short - term basis is supported, but the upward space is limited. For ethylene glycol, the supply and demand are expected to be balanced with minor fluctuations in August. Short - fiber supply and demand both increase slightly, and prices are expected to oscillate within a certain range. Bottle - chip prices follow the cost end, and the processing fee space depends on demand [4]. - **Methanol**: The port inventory is at a relatively high level year - on - year due to high imports in August. The demand is differentiated, with the traditional sector remaining weak and MTO profits recovering. The 09 contract is facing significant inventory accumulation, while the 01 contract is supported by seasonal peak season and gas - limit expectations [11]. - **Chlor - alkali Industry**: For caustic soda, the market sentiment is weakening, and the supply is expected to increase. For PVC, the supply - demand pressure remains high due to new capacity release and weak demand [20]. - **Polyolefin**: In the static view, the supply and demand of PP/PE both increase, inventory is being destocked, and the basis is weak. Strategically, the market is expected to oscillate in the short term [23]. - **Pure Benzene - Styrene**: For pure benzene, the supply is expected to improve in the third quarter, and short - term prices are supported, but it is under pressure in the medium - term. For styrene, the supply is high, but there are maintenance expectations as profits are compressed, and the downstream load is rising [32]. - **Crude Oil**: Overnight oil prices were weak, mainly driven by geopolitical expectations. In the short term, oil prices are expected to continue to oscillate weakly, and it is recommended to expand the spread between October - November/December contracts [35].

1. Report Industry Investment Rating No information provided. 2. Core View of the Report - Pure benzene port inventory continues to decline slightly, and its basis has stabilized and strengthened recently. From August to September, there are maintenance plans for aromatics in South Korea, and the import pressure has not increased further. The overall downstream operating rate remains high, and the demand is at a seasonal high, which drives the de - stocking of pure benzene, but the de - stocking range is expected to be limited. - For styrene, the port inventory did not continue to decline at the beginning of the week, and the port pickup volume did not continue to increase. Among the downstream products, the operating rates of EPS and PS have rebounded, and their inventory pressures have been relieved, while ABS still maintains a state of high inventory and low operating rate [3]. 3.

China may resume urea exports to India, opening an incremental market window. The policy requires concentrated exports by the end of September, overlapping with the domestic autumn storage period and creating demand resonance. The short - term market is likely to fluctuate strongly, and future attention should be paid to the impact of enterprise maintenance on daily production, changes in rigid and reserve demand, and export port collection [1]. Polyester Industry Chain - **PX**: Domestic PX supply is expected to increase, and the supply - demand situation in August is expected to weaken marginally. However, due to the traditional peak demand season and new PTA device commissioning expectations, the medium - term supply - demand pressure is not significant. It is expected that PX prices will be supported at low levels, but the upward space is limited. It is recommended to treat PX11 as a short - term range of 6600 - 6900 and expand the PX - SC spread at low levels [4]. - **PTA**: In August, due to low processing margins, PTA device maintenance plans increased, and short - term basis was supported. However, with the commissioning of new devices, the medium - term supply - demand is expected to be weak, and the upward space for the basis is limited. In the short term, there is still some support, and it is recommended to treat TA as a short - term range of 4600 - 4800 and conduct reverse arbitrage on TA1 - 5 at high levels [4]. - **MEG**: Domestic coal - based MEG supply has increased, and overseas supply is expected to change. In August, the supply - demand is near balance, and it is expected to fluctuate with commodities. It is recommended that EG01 fluctuate in the range of 4300 - 4500 in the short term [4]. - **Short - fiber**: Both supply and demand have increased slightly. With the approaching of the peak demand season, there is some support for prices, but the cost - side drive is limited. It is recommended that PF10 fluctuate in the range of 6300 - 6500 in the short term, and the processing margin on the futures market fluctuate in the range of 800 - 1100 [4]. - **Bottle - chip**: During the peak consumption season in August, with device production cuts, the processing margin has support at the bottom. The absolute price still follows the cost - side. It is recommended that PR is similar to PTA in terms of unilateral trading, and the main - contract processing margin on the futures market is expected to fluctuate in the range of 350 - 500 yuan/ton, and go long on the processing margin at low levels in the short term [4]. Methanol - The current methanol market has a relatively high port inventory year - on - year, mainly due to a large amount of imports in August, and imports in September are still expected to exceed 1.4 million tons. The demand side is differentiated, with the traditional sector remaining weak, while MTO profits have improved. Attention should be paid to the start - up progress of a port MTO device at the end of August to early September. The 09 contract has accumulated a large amount of inventory, while the 01 contract is supported by the seasonal peak season and Iranian gas - restriction expectations [7][8]. Chlor - alkali Industry - **Caustic Soda**: The overall sentiment in the industrial product futures market has weakened. The caustic soda market rebounded previously and then fell back. The spot market trading is okay, and the spot price is generally stable. The demand has been good recently, but there is an expectation of increased supply in the future, and the increase in the number of warehouse receipts in the main production areas also has a negative impact. It is recommended to try short - selling [14]. - **PVC**: The supply side has new production capacity being put into operation, the domestic trade is weak, and the inventory pressure is increasing. The demand is difficult to improve, and the downstream industry is still in the off - season. It is recommended to be bearish [14]. Polyolefin - Static analysis shows that the supply and demand of PP/PE both increase, inventory is being depleted, and the basis is weak, with high warehouse receipts suppressing the market. Dynamically, PP has more unplanned maintenance and new device delays, and PE has increased maintenance from mid - August to early September, with supply decreasing and demand recovering. In terms of valuation, oil - end profits are good, MTO profits are restored, and PDH profits decline slightly. It is recommended that the unilateral market fluctuate in the short term and continue to hold the LP01 contract [19]. Pure Benzene - Styrene - **Pure Benzene**: In the third quarter, the supply - demand situation of pure benzene is expected to improve, and port inventory is expected to decline in August, providing some support for prices. However, the overall supply is still sufficient, and its own driving force is limited. It is expected to be relatively strongly supported in the short term but will be under pressure in the medium term. BZ2603 should follow the fluctuations of oil prices and styrene [21][22]. - **Styrene**: The short - term supply of styrene remains high, but with profit compression, some devices may be shut down for maintenance. Downstream 3S loads have increased, and export expectations have increased due to overseas device maintenance. The supply - demand situation is expected to improve, and port inventory is expected to continue to decline. It is expected that styrene prices will be supported at low levels, but the rebound is limited. It is recommended that EB09 fluctuate in the range of 7100 - 7400 in the short term and be treated as a short - selling opportunity on rebounds [22]. Crude Oil - Overnight oil prices were weak, mainly due to the expected increase in Russian supply from the proposed Russia - Ukraine summit by Trump and market concerns about oversupply. However, the gasoline crack spread has rebounded, and refinery processing volume is at a seasonal high, providing some support for oil prices. It is expected that oil prices will continue to fluctuate weakly in the short term. It is recommended to be bearish, expand the spread between October - November/December contracts at low levels, and wait for opportunities to expand the spread in the options market after volatility increases [24][26]. 3.
