The profit margin of domestic alumina enterprises is narrowing, and the support for spot prices is weak. The inventory in North China is rising, while that in East China is falling. In the Shandong market, due to the approaching National Day holiday, there may be a price cut in the short - term [2]. - **PVC**: Last week, the PVC futures rebounded due to macro - warming, but the supply - demand contradiction is still difficult to ease. Next week, the output is expected to increase as many enterprises finish maintenance. The downstream demand is limited, and the procurement enthusiasm is average. The cost provides bottom - support. It is expected that PVC will stop falling and stabilize in September - October [2]. Urea Industry The urea futures are weakly declining. The supply may increase, and the demand from the autumn fertilizer market and industry is weak. The export new orders are limited. If there is no export surge or early shutdown of gas - based plants, the price may fall below 1,550 yuan/ton [7]. Pure Benzene - Styrene Industry - **Pure Benzene**: The weekly supply - demand of pure benzene is weak. In September, the supply may remain at a high level, and the demand support is weak. The price driving force is weak. The strategy for BZ2603 is to follow the styrene fluctuations [13]. - **Styrene**: The weekly supply - demand of styrene is also weak. The strategy is to be bearish on the absolute price rebound of EB11, and expand the spread between EB11 and BZ11 at a low level, but the driving force is limited [13]. PX - PTA - MEG Industry - **PX**: The supply of PX may increase due to short - process capacity increase and postponed maintenance. The demand is affected by PTA maintenance. The price is under pressure, and the basis boost is limited [17]. - **PTA**: The processing fee of PTA is low, and new device production is postponed. The demand is in the peak season, but the basis and processing fee repair drive is insufficient. The absolute price follows the cost [17]. - **MEG**: The supply - demand of MEG is gradually weakening. In the short - term, the import is not high, and the basis is oscillating at a high level. In the long - term, it will enter the inventory accumulation period in the fourth quarter [17]. - **Short - fiber**: The short - fiber supply is high, and the demand is limited during the peak season. The price has support at the low level, but the rebound drive is limited [17]. - **Bottle chips**: The bottle chip device restart and shutdown coexist. The downstream replenishment supports the price and processing fee, but the increase is limited [17]. Polyolefin Industry PP production has decreased due to losses in PDH and external propylene procurement routes, and the inventory has declined. PE maintenance has reached a peak, and the operating rate is rising. The upper - middle stream inventory has decreased. North American import offers are increasing. The inventory accumulation pressure of 01 contract is large, limiting the upside [22]. Methanol Industry The market is trading high inventory and fast Iranian loading. The coastal inventory has reached a historical high, the market sentiment is poor, and the price is weak. The domestic supply is at a high level year - on - year, and the demand is weak. The overall valuation is neutral. The market is swinging between high inventory and overseas gas - limit expectations. Attention should be paid to the inventory turning point [30][32]. Crude Oil Industry Last week, oil prices fluctuated weakly. The geopolitical premium has declined, and the market focuses on the weak supply - demand fundamentals. The supply is expected to be in surplus, and the demand is weak. The short - term oil prices are under pressure.

Report Industry Investment Rating - No relevant information provided Core Viewpoints of the Report - PTA prices declined and the basis weakened due to weak crude oil market, concerns about PX unit maintenance delays, and sufficient spot supply. Meanwhile, the decline in prices was beneficial for downstream cost reduction. The domestic PTA production increased as PTA units gradually resumed operation, leading to a rapid decline in the PTA basis and market pressure. The increase in OPEC+ oil production caused a significant drop in crude oil prices, and the spread between PX and naphtha narrowed.

Report Industry Investment Ratings No information provided in the reports regarding industry investment ratings. Core Views Chlor - Alkali Industry - Last week, the caustic soda futures stopped falling and rebounded on Friday. Next week, the supply is expected to increase, and the operating rate of sample manufacturers will rise. The alumina price has been falling, squeezing the profit of domestic alumina enterprises and weakening the support for the spot price. In Shandong, due to the approaching National Day holiday, there may be a price cut in the short - term. [2] - Last week, PVC futures rebounded with the support of a warming macro - environment, but the supply - demand contradiction is still difficult to resolve. Next week, the output is expected to increase as many enterprises finish maintenance. The downstream product operating rate has limited improvement, and the procurement enthusiasm is average. It is expected that PVC will stop falling and stabilize from September to October. [2] Urea Industry - The urea futures are in a weak downward trend. The supply is increasing rapidly, and it is expected to reach 210,000 tons in October. The demand is weak, with a short window for autumn fertilizer procurement, high finished - product inventory of compound fertilizers, and slow follow - up of export orders. Without variables such as increased exports or early shutdown of gas - based plants, the spot price may continue to decline, and the futures will continue to fall significantly only if the spot price breaks below 1,550 yuan/ton. [8] Pure Benzene - Styrene Industry - The weekly supply - demand of pure benzene is weak. In September, the supply may remain high as some plants restart or postpone maintenance. The demand is weak as most downstream products are in the red, some secondary - downstream inventories are high, and styrene plants plan to reduce production in September - October. The price driving force is weak. [10] - The situation of styrene is similar to that of pure benzene. The supply - demand is expected to be loose in September, and the price driving force is weak. [10] Polyester Industry Chain - For PX, the supply has increased significantly due to delayed maintenance of some domestic plants, while the demand is weak as PTA processing fees are low, new PTA plants postpone commissioning, and many PTA plants plan to have maintenance. The PXN may be compressed in the fourth quarter, and the price driving force is weak. [14] - For PTA, the supply is expected to shrink, but the demand increase is limited, and the basis is not strongly supported. In the medium - term, the supply - demand is expected to be weak, and the price follows the raw material. [14] - For ethylene glycol, the short - term supply - demand is turning weak. Although the inventory is expected to decrease in September, the terminal market is weak. In the long - term, the supply - demand is expected to be weak in the fourth quarter due to new plant commissioning and seasonal demand decline. [14] - For short - fiber, the short - term supply - demand pattern is weak. The supply is high, and the demand is limited during the peak season. The price is supported at the low level but lacks upward driving force. [14] - For bottle - grade polyester chips, the supply - demand is still loose. Although the price and processing fees are supported by pre - holiday replenishment, the processing fee has limited upward space. [14][15] Polyolefin Industry - PP production has decreased recently due to losses in PDH and external - propylene procurement routes, leading to more unplanned maintenance and inventory decline. PE maintenance has reached a peak, and the operating rate is rising. The inventory of the upstream and mid - stream has decreased this week, and there are more import offers from North America. The 01 contract has a large inventory accumulation pressure, limiting the upward space. [20] Methanol Industry - The methanol market is trading high - inventory and fast loading in Iran. The coastal inventory has reached a record high, the market sentiment has worsened, and the price and basis have weakened slightly. The domestic supply is at a high level year - on - year, and although there is some unplanned maintenance recently, some plants are expected to resume production in mid - September, and the inventory pattern in the inland is relatively healthy. The demand is weak due to the traditional off - season. The port is still receiving a large amount of goods, with significant inventory accumulation and weak trading. The overall valuation is neutral. The futures are oscillating between high - inventory reality, weak basis, and overseas gas - restriction expectations in the future. [45] Crude Oil Industry - Last week, oil prices were weakly oscillating. The geopolitical premium has declined, and the market has refocused on the weak supply - demand fundamentals. The meeting between Chinese and US leaders has eased concerns about secondary sanctions on China for purchasing Russian oil, reducing the geopolitical risk support for oil prices. The expectation of future supply surplus, combined with the refinery maintenance season and the unexpected increase in US distillate inventory, has put pressure on oil prices. In the short - term, oil prices are under pressure.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Short - fiber: In the short - term, it is a volatile market, and in the medium - term, it is weak. In September, the supply and demand are both strong. With low prices, the replenishment support is strong, but the cost support is insufficient, showing a unilateral volatile and weak trend. The recommended strategy is to hold the inter - period positive spread [7]. - Bottle chips: The cost support is insufficient, showing a volatile and weak trend. In September, the supply increases while the demand decreases. The low - price procurement support is strong, but there is a risk of inventory accumulation in the future. The recommended strategy is to go long on TA and short on PR in the far - month contract [8]. Summary by Relevant Catalogs 1. Short - fiber (PF) 1.1 Valuation and Profit - The current spot premium is 1000 - 1100 yuan/ton, which is relatively high; the disk processing fee is 970 yuan/ton, and the processing fee and inter - month spread valuations are basically reasonable, while the basis is high [7]. 1.2 Fundamental Operation - Supply: The factory's average operating rate has slightly increased to 95.4%, and the spinning direct - spun polyester staple fiber operating rate is 98%. It is expected to fluctuate in the range of 93% - 95% in the future [7]. - Demand: In the second half of the week, when the price dropped to a low level, downstream procurement increased. The short - fiber inventory decreased, with the 1.4D equity inventory at 7.8 days and the physical inventory at 18 days. In September, the downstream operating load increased month - on - month, and each link was in the trend of seasonal inventory reduction [7]. 1.3 Strategy - Unilateral: None - Inter - period: Hold the inter - period positive spread - Cross - variety: None [7] 2. Bottle chips (PR) 2.1 Valuation and Profit - The spot processing fee is 450 yuan/ton, and the processing fees of the October and November disk contracts are 400 - 420 yuan/ton, all of which are over - estimated [8]. 2.2 Fundamental Operation - Supply: The factory maintains production cuts, with the operating rate at around 81%. The new Fuhai plant is expected to be put into operation in late October or at the end of the month [8]. - Demand: Domestically, the beverage factory's operating rate has dropped to around 85%. The inventory of bottle - chip factories has slightly decreased to 14.5 days. The export volume is expected to maintain at around 600,000 tons in August and September [8]. 2.3 Strategy - Unilateral: None - Inter - period: None - Cross - variety: Go long on TA and short on PR in the far - month contract [8] 3. Cost and Raw Materials - PTA: It is operating weakly, and the warehouse receipts are continuously flowing out [35] - MEG: The subsequent supply pressure will increase month - on - month [44] - Cost and profit: The cost has decreased, and the profit has been repaired. The polymerization cost has dropped to around 5400 yuan/ton, and the bottle - chip processing fee is oscillating at a high level [46] 4. Inventory - Polyester factories' overall PTA inventory has increased, and the domestic polyester bottle - chip factory inventory has slightly decreased to around 14.5 days. It is expected to have a slight inventory accumulation in September [50][55] 5. Device Changes - In September, about 400,000 tons of the planned 1,000,000 - ton device will resume production. Some factories are maintaining production cuts, and new devices such as Fuhai are expected to be postponed [56] 6. Demand - Beverage consumption from January to August 2025 is weaker year - on - year. However, there are still many new beverage factory production lines to be put into operation. The demand for edible oil is neutral, and the demand for sheet materials is driven by the expansion of ready - to - drink beverages in the sinking market and the take - away war [63][67][72] 7. Export - In July 2025, the export volume of polyester bottle chips and slices increased year - on - year. The main export destinations are Southeast Asia, South Asia, Central Asia, Russia, and Eastern Europe. There are anti - dumping policies and investigations in some countries [82][84][93] 8. Supply - demand Balance Sheet - In September 2025, it is in a tight balance to a slightly inventory - accumulating state, and the pressure will increase in the future. The supply assumption is that mainstream factories maintain production cuts, and new devices will be put into operation. The demand assumption is that downstream demand will increase by 5% year - on - year during the peak season, and the export volume will maintain at around 600,000 tons [94][96]
