Report Industry Investment Rating - PX/PTA/PF/PR are rated neutral [4] Core Viewpoints - The postponement of the maintenance of two PX units has narrowed the de - stocking range of PX in the fourth quarter, weakening the previous de - stocking support. Coupled with more PTA maintenance plans, PX prices have fallen and PTA processing fees have widened [1] - The recent oil price has been oscillating, and the Russia - Ukraine situation should be monitored. The PX load in China has gradually recovered, and the PX balance sheet in September has changed from de - stocking to a loose balance. However, PX is still in a low - inventory state [1] - The PTA load is rising from a low level. The short - term de - stocking fundamentals are okay, but there is a risk of inventory accumulation in the fourth quarter due to new device commissioning expectations. The demand recovery is limited, and the polyester load increase is restricted [2] - The polyester start - up rate shows signs of recovery, but order connection is insufficient. It is expected that the polyester load will remain stable with a slight increase in September [2] - The short - term supply - demand situation of direct - spinning polyester staple fiber is better than that of the raw material end, and the processing margin has widened. The bottle - chip processing fee is expected to fluctuate slightly, and there is still large supply - demand pressure under the new device commissioning [3] - For the strategy, it is recommended to go long on the PF processing fee at low prices in cross - variety trading, and there is no recommendation for cross - period trading [4] Summary by Directory Price and Basis - The report shows the TA main contract, basis, and inter - period spread trends; PX main contract trends, basis, and inter - period spread trends; PTA East China spot basis; and short - fiber 1.56D*38mm semi - bright natural white basis [9][10][13] Upstream Profit and Spread - The report presents PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [16][19] International Spread and Import - Export Profit - The report includes toluene US - Asia spread, toluene South Korea FOB - Japan naphtha CFR, and PTA export profit [24][26] Upstream PX and PTA Start - up - The report shows the PTA load in China, South Korea, and Taiwan, as well as the PX load in China and Asia [27][30][34] Social Inventory and Warehouse Receipts - The report presents the weekly social inventory of PTA, monthly social inventory of PX, total PTA warehouse receipts + forecast volume, PTA warehouse receipt inventory, PX warehouse receipt inventory, and PF warehouse receipt inventory [36][39][45] Downstream Polyester Load - The report shows the production and sales of filament and short - fiber, polyester load, direct - spinning filament load, polyester staple fiber load, polyester bottle - chip load, factory inventory days of various filaments, and the start - up rates of Jiangsu and Zhejiang looms, texturing machines, and printing and dyeing machines, as well as the profits of filament FDY and POY [49][51][62] PF Detailed Data - The report presents the polyester staple fiber load, factory equity inventory days of polyester staple fiber, 1.4D physical inventory, 1.4D equity inventory, recycled cotton - type staple fiber load, original - recycled spread, pure polyester yarn start - up rate, pure polyester yarn production profit, polyester - cotton yarn start - up rate, polyester - cotton yarn processing fee, and the available inventory days in pure polyester yarn and polyester - cotton yarn factories [71][73][83] PR Fundamental Detailed Data - The report shows the polyester bottle - chip load, bottle - chip factory inventory days, bottle - chip spot processing fee, bottle - chip export processing fee, bottle - chip export profit, price difference between East China water bottle chips and recycled 3A - grade white bottle chips, and bottle - chip inter - month spreads [91][93][101]

Report Industry Investment Rating No information provided. Core Views - The PTA maintenance plans have increased under low processing fees, such as Hengli and Dushan Energy planning to conduct maintenance in October and November respectively. The PTA futures closed up in a volatile manner on Wednesday, the negotiation atmosphere in the spot market was average, and individual mainstream suppliers reduced the contract supply in October, leading to a slight strengthening of the spot basis [1]. - In terms of the cost side, the oil price has been fluctuating recently, and attention should be paid to the Russia-Ukraine situation. The oil price has rebounded since last Friday. On the one hand, the Russia-Ukraine negotiations have been suspended again. On the other hand, the US military carried out a military operation in the offshore area of Venezuela, which raised concerns about Venezuela's national security. The PXN was 229 US dollars/ton (a month-on-month change of +1.63 US dollars/ton) the day before last. The negotiation on the floating price of PX was deadlocked, and the PXN weakened to 230 US dollars/ton and then fluctuated. Recently, the PX load in China has gradually recovered. With the increase in PTA maintenance, the PX balance sheet in September has changed from destocking to a loose balance, but the overall PX inventory is still at a low level. As the PTA devices resume operation, the PX will turn to destocking again. Considering the rigid demand for PX from new PTA devices, there is support below the PXN. Continued attention should be paid to window negotiations and warehouse receipt situations [2]. - In terms of TA, the spot basis of the TA main contract was -77 yuan/ton (a month-on-month change of +3 yuan/ton), the PTA spot processing fee was 130 yuan/ton (a month-on-month change of -1 yuan/ton), and the processing fee on the main contract's disk was 332 yuan/ton (a month-on-month change of +6 yuan/ton). The PTA load is increasing from a low level, and the near-term destocking fundamentals are acceptable. However, there is a pressure of inventory accumulation in the fourth quarter due to the expected commissioning of new devices. Recently, mainstream suppliers have been selling goods, and the market's spot supply is relatively abundant. At the same time, the recovery of the demand side is limited, and the order connection is insufficient under high inventory. The increase in polyester load is limited [2]. - In terms of demand, the polyester operating rate was 91.6% (a month-on-month increase of 0.3%). The current demand shows signs of recovery, but the order connection is insufficient, mainly with local scattered orders. The high inventory of grey fabrics is being depleted slowly. The market's expectation for the subsequent demand level is neutral to pessimistic. Most terminal raw material purchases maintain a cautious wait-and-see attitude, digesting previous stocks while following up with rigid demand. In terms of polyester load, the inventory of filament is not high but gradually accumulating. It is expected that the load of filament and staple fiber will continue to stabilize and slightly rebound in September. The load of bottle chips is expected to increase slightly, but the increase may be limited. It is expected that the polyester load will stabilize and slightly rebound in September, with the average monthly load likely to be below 91.5% [3]. - In terms of PF, the spot production profit was 175 yuan/ton (a month-on-month change of -6 yuan/ton). Direct-spun polyester staple fiber fluctuated and consolidated following the raw materials, and the load continued to increase slightly. As the price difference between high and low prices in the market narrowed, factory sales improved, inventory decreased, the demand for staple fiber at a low price was acceptable, the factory inventory was low, and currently, the inventory held by traders was small. In the short term, the supply-demand situation of direct-spun polyester staple fiber was better than that of the raw material side. Due to the relatively weak performance of raw materials, the processing margin of direct-spun polyester staple fiber expanded to over 1000 [3]. - In terms of PR, the spot processing fee of bottle chips was 454 yuan/ton (a month-on-month change of -11 yuan/ton). The fundamentals of bottle chips have not changed much. The current order receipt and shipment performance of bottle chips are average. It is reported that the industry's overall target of 20% production reduction and suspension in September remains unchanged. It is expected that the subsequent increase in bottle chip load will be limited, the overall inventory pressure of factories has decreased, and the processing fee of polyester bottle chips is expected to maintain small fluctuations. Under the pressure of the commissioning of the new Fuhai device in the future, the supply-demand pressure is still relatively large, and production reduction is needed for adjustment. It is expected that the spot processing fee of bottle chips will fluctuate within a range. Attention should be paid to the fluctuation of raw material prices [4]. - Strategy: For single-sided trading, the ratings for PX/PTA/PF/PR are neutral. For PX, since August, PX devices have been restarted intensively. With the increase in PTA maintenance, the fundamentals have weakened month-on-month, and the PXN has loosened. However, with low inventory and the restart of PTA, the PX will turn to destocking again, and there is support below the PXN. For TA, the PTA load is increasing from a low level, and the near-term destocking fundamentals are acceptable. However, there is a pressure of inventory accumulation in the fourth quarter due to the expected commissioning of new devices. Recently, mainstream suppliers have been selling goods, and the market's spot supply is relatively abundant. At the same time, the recovery of the demand side is limited, and the order connection is insufficient under high inventory. The increase in polyester load is limited. For PF, the demand for PF has improved slightly, the inventory has started to decrease, the demand at a low price is acceptable, and currently, the inventory held by traders is small. In the short term, the supply-demand situation of direct-spun polyester staple fiber is better than that of the raw material side, but its upward momentum is not strong. For PR, several major manufacturers have extended their maintenance plans. It is expected that the spot processing fee of bottle chips will fluctuate within a range. Attention should be paid to the fluctuation of raw material prices. For cross-variety trading, go long on the PF processing fee at low prices: PF2511 - 0.855PTA2601 - 0.332MEG2601. There is no strategy for cross-period trading [5].

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Due to weak demand and inventory pressure, ethylene glycol is likely to continue its downward trend. The price center may further test the support level of the next range, and if port destocking continues to face obstacles and demand does not improve, the downward pressure may increase [1][2] - Supply has a slight decline, but demand remains sluggish, and inventory pressure is increasing, especially the rapid accumulation of port inventory, which may suppress prices. Although the strengthening basis shows that the spot is relatively resistant to decline, the weakness of the futures main contract and the shrinking trading volume indicate insufficient market confidence. Therefore, the price may maintain a low - level oscillation, and attention should be paid to changes in the cost side and demand recovery [22][23] Summary by Relevant Catalogs 1. Daily Market Summary - **Price and Basis**: The price of the ethylene glycol main futures contract dropped slightly by 3 yuan to 4,319 yuan/ton, showing a four - day oscillating decline. The East China spot price also fell by 5 yuan to 4,435 yuan/ton, and the basis widened by 3 yuan to 121 yuan/ton, indicating a premium structure of the spot relative to the futures. The far - month spread fluctuated significantly, with the 1 - 5 spread widening to - 37 yuan and the 5 - 9 spread changing from premium to discount of 12 yuan, suggesting a weak market expectation for medium - term supply and demand [1] - **Position and Trading Volume**: The trading volume of the main contract decreased significantly by 77,639 lots to 106,908 lots (a decline of 42%), and the position decreased slightly by 190 lots, reflecting a decrease in market trading activity and an increase in the wait - and - see sentiment of funds [1] - **Supply Side**: The total ethylene glycol operating rate dropped slightly by 0.14 percentage points to 71.24%. Among them, the oil - based operating rate decreased by 0.24% month - on - month, while the coal - based and methanol - based plant operating rates remained stable. Despite the continuous loss of coal - based production at - 338 yuan/ton, the willingness to overhaul did not increase significantly, and the overall supply remained at a high level [1] - **Demand Side**: The load rate of polyester factories remained stable at 89.42%, and the load of Jiangsu and Zhejiang looms remained at a low level of 63.43% for many consecutive days. Terminal orders showed no improvement, and the rigid demand support of the polyester segment for ethylene glycol was limited [1] 2. Inventory and Related Analysis - **Inventory**: The inventory at the East China main port increased to 48.57 tons (a week - on - week increase of 13.7%), and the inventory in Zhangjiagang soared by 40.6% to 18 tons, reaching a recent high. Although the arrival volume decreased by 6.7 tons to 10.17 tons, the port inventory accumulation pressure remained unresolved [2] - **Cost - Supply and Demand Relationship**: The coal - based production continued to incur losses, but the plants did not significantly reduce production. The oil - based and methanol - based operating rates remained stable, and the overall supply was loose. The rigid demand support of polyester was insufficient, the terminal weaving operating rate remained low, and the inventory climbed to a new high this year, suppressing market confidence [2] 3. Industry Dynamics and Interpretation - On September 10, the East China US dollar market negotiation remained stable, with near - month cargoes negotiated in the range of 520 - 523 US dollars/ton. The Shaanxi ethylene glycol market spot price remained stable, with the market average price around 3,990 yuan/ton for self - pick - up. The mainstream market was stable, and downstream players purchased as needed. The South China market spot was weakly stable, with the market negotiation atmosphere being cold, and the current price around 4,470 yuan/ton for delivery [5] - On September 10, market concerns about the escalation of the conflict in the Middle East supported the rise in oil prices. However, the commissioning of new ethylene glycol plants has been further implemented, and the spot basis in the market has narrowly shrunk. The current negotiation reference price in East China is around 4,437 yuan/ton [5] 4. Industry Chain Data Charts The report provides multiple data charts, including the closing price and basis of the ethylene glycol main contract, ethylene glycol production profit, domestic ethylene glycol plant operating rate, downstream polyester plant operating rate, ethylene glycol East China main port inventory statistics (weekly), and ethylene glycol industry total inventory [6][8][10]

Report Summary 1. Market Overview - As of September 11th, domestic futures contracts showed mixed performance. Coking coal, industrial silicon, and red dates rose over 2%, while polysilicon, coke, pulp, apples, lithium carbonate, and soda ash rose over 1%. The container shipping index (European line) dropped over 5%, and 20 - rubber and iron ore fell nearly 1% [6]. - Stock index futures generally rose, with the CSI 300 futures (IF) up 2.64%, the SSE 50 futures (IH) up 1.56%, the CSI 500 futures (IC) up 3.44%, and the CSI 1000 futures (IM) up 2.94%. Treasury bond futures also had mixed results, with the 2 - year (TS) up 0.06%, the 5 - year (TF) up 0.14%, the 10 - year (T) up 0.07%, and the 30 - year (TL) down 0.11% [6][7]. - In terms of capital flow, as of 15:30 on September 11th, the CSI 300 2509, CSI 500 2509, and SSE 50 2509 had capital inflows of 1.584 billion, 1.533 billion, and 0.68 billion respectively. Meanwhile, the Shanghai gold 2510, CSI 1000 2509, and Shanghai silver 2510 had outflows of 1.252 billion, 0.605 billion, and 0.376 billion respectively [7]. 2. Core Views Copper - The US August PPI was lower than expected. China's copper ore imports increased by 7.4% year - on - year in August. Refining fees are falling, and 5 smelters plan to have maintenance in September, which may lead to a decline in domestic electrolytic copper production. Imported copper will affect the domestic market. Demand is weak, and the market is expected to be volatile and slightly stronger [9]. Crude Oil - The seasonal travel peak is over, and US oil inventories are increasing. OPEC + will adjust production in October, which may increase pressure in Q4. Saudi Aramco cut prices. The market should watch the progress of the Russia - Ukraine cease - fire negotiation and India's oil purchases. It is recommended to short at high prices in the medium - to - long - term and close short positions in the short - term [10][11]. Asphalt - Supply is decreasing, and demand is also weak due to factors like weather and capital. OPEC +'s planned production increase will weaken cost support.
