The estimated price of PX on the 21st was 854 dollars/ton, up 17 dollars from the 20th [3] - **PTA**: A 250 - million - ton PTA plant in South China shut down for maintenance on the 21st, and another 250 - million - ton plant is expected to shut down around August 23rd for over a month. As of Thursday, the PTA load was 71.6%, and the operating rate was around 77.4% [3] - **MEG**: As of August 21st, the overall operating load of ethylene glycol in mainland China was 73.16% (up 6.77% from the previous period), and the operating load of ethylene glycol produced by oxalic acid catalytic hydrogenation (syngas) was 81.25% (up 0.78% from the previous period) [5] - **Polyester**: There were no changes in the whole polyester plants this week, but the local plant loads increased, and the overall polyester load in mainland China was around 90% as of Thursday. The operating load of major domestic polyester industrial yarn manufacturers remained stable, and the overall theoretical operating load of domestic polyester industrial yarn recovered to around 71% [5] Price and Spread Data | Futures | PX | PTA | MEG | PF | SC | | --- | --- | --- | --- | --- | --- | | Yesterday's Closing Price | 6958 | 4860 | 4473 | 6614 | 490.9 | | Change | 6844 | 82 | - 4 | 110 | 8.1 | | Change Rate | 1.67% | 1.72% | - 0.09% | 1.69% | 1.68% | | Month Spread (Yesterday's Closing Price) | 162 | - 14 | - 54 | - 42 | - 6.2 | | Month Spread (Change) | 74 | 42 | - 4 | 20 | 0.7 | | Spot Price (Yesterday) | 852.33 dollars/ton | 4830 yuan/ton | 4518 yuan/ton | 584.5 dollars/ton | 68.12 dollars/barrel | | Spot Price (Change) | 14.33 | 144 | 16 | 9 | 0.57 | | Spot Processing Fee (Yesterday) | 255.5 | 197.31 | 175.93 | 27.32 | - 6.01 | | Spot Processing Fee (Change) | 2.5 | - 10.67 | 43.46 | 4.44 | 0 | [2] Trend Intensity - PX trend intensity: 1 (indicating a "strong" view) [6] - PTA trend intensity: 1 (indicating a "strong" view) [6] - MEG trend intensity: 1 (indicating a "strong" view) [6] Sales Data - On the 21st, the overall sales of polyester yarn in Jiangsu and Zhejiang were fair, with an average sales rate of around 70% by 3:30 pm [5] - On the 21st, the sales of direct - spun polyester staple fiber improved, with an average sales rate of 89% by 3:00 pm [6]

Report Summary 1. Report Industry Investment Rating - The trend strength of p-xylene, PTA, and MEG is rated as "1", indicating a "slightly strong" outlook [6]. 2. Core Views of the Report - PX: With a significant reduction in overnight crude oil inventories and a strong rebound in oil prices, the short - term downside space for PX's unilateral price may be limited. Supported by cost and with improved demand expectations, and a tight supply - demand pattern, the unilateral price of PX is expected to rebound. For the spread, focus on the 11 - 01 positive spread. The PX - naphtha valuation is at a moderately high level, with a tight supply - demand pattern in September and downward pressure on PXN after the 01 contract [6]. - PTA: Cost support is strong, and the 9 - 1 reverse spread should be held. With an improvement in terminal textile and clothing demand and a bottom - up rebound in polyester operating rates, the unilateral price of PTA is strong. The price and basis strengthened yesterday, and the downstream's willingness to hold goods increased [7]. - MEG: With a decrease in imports and arrivals and marginal destocking, the unilateral price of MEG is strong. The reduction of naphtha cracking capacity by the South Korean petrochemical group has disrupted the market sentiment of olefin - related products. Domestically, plants are operating at full capacity, imports are low, inventories are decreasing, and polyester operating rates are rising. In the short - term, a bullish view is maintained. In the long - term, the supply pressure of new plants in the 01 contract will limit the upside [7]. 3. Summary by Related Catalogs Market Dynamics - PX: The naphtha price rose at the end of the session. On the 20th, PX prices increased, with two October Asian spot transactions at $839 and $838, and one November Asian spot at $836. The PX valuation on the 20th was $837/ton, up $2 from the 19th. There were concerns about weak PX spot prices due to over - capacity in China, but hopes are placed on winter demand for polyester clothing [2][3]. - PTA: On the 20th, the PTA spot price remained at 4,690 yuan/ton, with a mainstream basis of 09 - 2 [5]. - MEG: South Korean petrochemical companies will cut capacity and restructure. A 750,000 - ton/year MEG plant in Malaysia has restarted, and there were tender transactions on the 20th [5]. - Polyester: The sales of polyester yarn in Jiangsu and Zhejiang on the 20th declined overall, with individual differences. The average sales volume was estimated to be slightly below 70%. The sales of direct - spun polyester staple fiber were generally average, with an average sales volume of 57% as of 3:00 pm [5][6].

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - PX cost support is weak, but terminal demand improves, and the month - spread remains strong. PX is expected to be stronger than oil prices, but the overall upside space may be limited, and the 9 - 1 month - spread will continue to strengthen [1][7]. - PTA is in a situation of weak reality and strong expectation, with a 9 - 1 month - spread reverse arbitrage. The unilateral price is in a volatile market with limited downside space for now [1][8]. - MEG has a low arrival volume this week, and the basis strengthens. The unilateral price is mainly in a volatile market, and the 9 - 1 month - spread should be operated in the range of - 50 to 0, with a 1 - 5 reverse arbitrage [1][8]. 3. Summary According to Related Catalogs Market Dynamics - PX: The price of naphtha at the end of the session remained strong, and the PX price increased. However, the low start - up of downstream PTA and the weak crude oil market restricted the rise of the PX market. Some October cargoes were traded at 836.5 - 837 dollars/ton [4]. - PTA: The spot price rose to 4,690 yuan/ton. The sentiment in the Asian PTA market remained sluggish due to concerns about over - capacity. A 760,000 - ton/year PTA plant in Taichung was shut down for planned maintenance [5]. - MEG: From August 18th to August 24th, the total planned arrival volume at major ports was about 54,000 tons [6]. - Polyester: The sales of polyester yarn in Jiangsu and Zhejiang were still weak, with an average sales rate of slightly less than 50% by 3:30 pm. The sales of direct - spun polyester staple fiber were average, with an average sales rate of 57% by 3:00 pm [6]. Trend Intensity - The trend intensity of p - xylene, PTA, and MEG is all 0, indicating a neutral trend [7]. Views and Suggestions - PX: Cost support is weak, but the PX fundamentals are tight. The 8 - month polyester start - up reached the bottom, and the 9 - month supply - demand is still tight. Pay attention to the restart progress of Fuhua Group [7]. - PTA: The unilateral price is in a volatile market. The supply is marginally tightened, and the demand improves month - on - month. The 9 - 1 month - spread reverse arbitrage should be maintained. Pay attention to the impact of the peak season on the industrial chain [8]. - MEG: The import arrival volume decreases, and the supply and demand both increase. The 9 - 1 month - spread should be operated in the range of - 50 to 0, with a 1 - 5 reverse arbitrage. Pay attention to the position reduction speed of the 09 contract [8].

Report Summary Industry Investment Ratings - PX: Unilateral trend is weakly bearish [7] - PTA: Unilateral trend is weakly bearish [7] - MEG: Unilateral trend is weakly bearish and in a weak oscillation [7] Core Views - PX: From late August, pay attention to the recovery of terminal orders, and PXN has short - term support [7] - PTA: Hold the mid - term strategy of going long on MEG and short on PTA. With low processing fees, focus on unplanned production cuts and the positive spread of September - January contracts. Supply decreases while demand increases as polyester operating rate rises to 89.4% [7] - MEG: Hold the mid - term strategy of going long on MEG and short on PTA. Keep the September - January spread in the range of - 50 to 0; pay attention to the reverse spread of January - May contracts. The sharp decline in coal prices yesterday had a negative impact on the chemical sector [7] Market Dynamics - **PX**: On August 14, the price of PX decreased. One October Asian spot was traded at $824. The end - of - session physical goods had no negotiation for September, and October was negotiated at $820/825, with an asking price of $825 for November.
