1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating. 2. Core Views of the Report - The unplanned shutdown of large - scale PTA plants has led to a significant increase in prices. The shutdown of two 2.5 - million - ton plants of Hengli will affect 5 million tons of PTA production capacity, accounting for 5.5% of the total PTA production capacity and 30% of Hengli's total PTA production capacity. This may cause a monthly loss of up to 400,000 tons, and the supply - demand situation in September will change from balance to significant de - stocking[1]. - In terms of cost, the meeting between the US and Russian presidents ended with a good negotiation atmosphere but no agreement. The geopolitical situation continues to impact crude oil prices, which are in a short - term range - bound pattern. The PX balance sheet has shifted from de - stocking to inventory accumulation, but the overall PX inventory remains low, and there is support below the PXN[2]. - The most pessimistic period for PTA demand has passed. With the increase in PTA maintenance, the supply - demand situation has improved, and the de - stocking amplitude from August to September has significantly increased. However, the supply of old goods is abundant due to the concentrated cancellation of warehouse receipts[2]. - The polyester operating rate is 89.4% (a month - on - month increase of 0.6%). The most pessimistic period of the off - season for demand has passed, and there are signs of improvement in local orders. The polyester load is expected to remain stable and continue to rise in the short term[3]. - For PF, the demand has improved slightly but is limited. The near - month 09 contract is suppressed by the logic of forced cancellation of warehouse receipts. For PR, several major manufacturers have extended their maintenance plans, and the spot processing fee for bottle chips is expected to recover and then return to range - bound fluctuations[3][4]. 3.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - For PTA, although it remains in a state of inventory accumulation, the absolute inventory level is not high. With the current low processing fees for spot goods persisting for some time, and considering the limited inventory pressure of filament and the continuous inventory reduction of bottle - grade chips at low operation rates, the polyester operation rate is expected to gradually stabilize and has upward potential. It is advisable to look for opportunities to expand processing fees by buying at low prices [2]. - For MEG, the short - term inventory accumulation pressure is not significant, and the port inventory is expected to remain at a low level. The situation is favorable and the profit margin is decent. However, in the far - term, there is an expectation of inventory accumulation due to the restart of overseas plants and the further increase of coal - based operation rates. The valuation is greatly affected by the subsequent evolution of the cost side, and it should be regarded as a wide - range fluctuation. Attention should be paid to the restart progress of satellite plants [2]. - For polyester staple fiber, as the finished - product inventory of the polyester yarn end is reduced, the downstream operation rate may increase. Although the supply of staple fiber itself may also increase, considering that the processing fees on the futures market are still in a relatively low range, opportunities to expand processing fees by buying at low prices can be considered [2]. - For natural rubber and 20 - grade rubber, the national explicit inventory remains stable at a relatively low level but does not show seasonal reduction. The price of Thai cup - lump rubber has rebounded due to rainfall affecting rubber tapping. The strategy is to wait and see [2]. Summary by Related Catalogs PTA - **Price and Margin Changes**: From August 1 to August 7, crude oil prices dropped from $69.7 to $66.4, PTA internal - market spot prices decreased from 4750 to 4690, and PTA processing fees decreased from 121 to 101.

The EPS domestic profit decreased from 320 to 200 [5].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - BZ port inventory decreased slightly without further accumulation. Short - term downstream demand for BZ is okay, but CPL and styrene开工 rates have declined, and there is still some finished - product inventory pressure downstream, with a drop in phenol - acetone开工 rate. On the supply side, the shipping pressure from South Korea has not further increased, but the new production capacity of Yulong Petrochemical in China has an impact, and BZ processing fees continue to consolidate at a low level [3]. - For styrene, the port inventory declined again during the week. The port basis and the 09 - 10 inter - period spread of futures rebounded from the bottom. Combined with the increase in downstream提货 volume, it reflects the speculative demand for the peak seasons of "Golden September and Silver October" has emerged. However, the production schedule of white goods at the terminal is still average, there is still inventory pressure for downstream PS and ABS, and the production profit of hard plastics is also average, so the sustainability of restocking is in doubt [3].

Strategies - Unilateral: Hold a wait - and - see attitude towards pure benzene and styrene [4]. - Basis and Inter - period: Conduct reverse arbitrage when the spread between near - month BZ paper cargo and distant BZ2603 is high, and conduct reverse arbitrage when the BZ2603 - BZ2605 inter - period spread is high; conduct reverse arbitrage when the EB2509 - 2510 inter - period spread is high [4]. - Cross - variety: Shrink the EB - BZ spread when it is high [4].

Report Industry Investment Rating - PX/PTA/PF/PR neutral [4] Core Viewpoints - The short - term market is range - bound, but the oil market will turn from boom to bust in the second half of the year as global refineries reach their annual peak operating rates and new supplies enter the market. Unless the US increases sanctions on Russia, leading to a significant decline in supply [1]. - The PTA spot processing fee is at a low level. Although the short - term supply - demand situation has improved due to PTA maintenance, it is expected to continue to accumulate inventory slightly in August. Attention should be paid to the dynamics of major suppliers [1][2]. - The polyester load remains firm in the short term, but the terminal demand has not improved significantly. The improvement of the demand side still needs to wait for the seasonal peak - season orders, which may start gradually in late August [2]. - PF is dragged down by downstream production cuts, with low inventory - holding willingness, and the near - month contract is suppressed by the logic of mandatory warehouse receipt cancellation. The PR processing fee is expected to return to the range of 300 - 500 yuan/ton after repair [3][4]. Summary by Directory 1.

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Views - **Market Analysis**: The closing price of the main EG contract was 4,389 yuan/ton (a change of -16 yuan/ton or -0.36% from the previous trading day), and the spot price in the East China market was 4,455 yuan/ton (a change of -25 yuan/ton or -0.56% from the previous trading day). The spot basis in East China (based on the 2509 contract) was 78 yuan/ton (a month-on-month increase of 5 yuan/ton). The ethylene-based EG production profit was -$49/ton (a month-on-month decrease of $3/ton), and the coal-based syngas EG production profit was 42 yuan/ton (a month-on-month decrease of 24 yuan/ton). The MEG inventory at the main ports in East China was 516,000 tons (a month-on-month decrease of 5,000 tons) according to CCF data and 427,000 tons (a month-on-month decrease of 48,000 tons) according to Longzhong data. The actual arrivals at the main ports last week were 103,000 tons, lower than the planned value, with a slight de-stocking of port inventory. This week, the planned arrivals at the main ports are 138,000 tons, and with concentrated arrivals at secondary ports, the main ports are expected to see inventory accumulation [2]. - **Supply - Demand Logic**: On the supply side, domestically, the syngas - based load of ethylene glycol has returned to a high level and can be further increased. Some EO - EG co - production units are switching from EO to EG. Overseas, the Saudi sharq series of plants have restarted, and the supply of ocean - going cargo is expected to gradually return to normal. On the demand side, there was concentrated restocking at the end - user level in July, relieving the inventory pressure of filament yarns. The polyester load is expected to remain stable in the short term, and attention should be paid to the order connection in August. There will be concentrated arrivals of foreign vessels at the beginning of August, with a slight inventory accumulation in the balance sheet. The port inventory is expected to remain low and slightly increase in August [3]. 3. Strategy - **Unilateral**: Be cautiously bearish due to weakening market sentiment and the decline of coking coal. - **Inter - period**: No strategy. - **Inter - variety**: No strategy [4]. 4.

1. Report Industry Investment Rating There is no information provided regarding the report's industry investment rating. 2. Core Viewpoints of the Report - PX fundamentals maintain a weak balance, with obvious resilience in terminal demand. In the short - term, PX prices follow the cost of crude oil. In the future, during the peak seasons of "Golden September and Silver October", there is significant potential for demand and production to increase [139]. - For PTA, with large - scale device maintenance plans in August and new device production, the monthly output is expected to change little. Downstream demand provides resilient support. If oil prices are further pressured, TA prices will follow suit. Attention should be paid to demand recovery, tariff implementation progress, and significant oil price fluctuations [139]. - Regarding MEG, the supply is recovering well, and there is still room for domestic production to increase. The downstream demand provides resilient support. The inventory inflection point may arrive, and supply - demand will shift to inventory accumulation. Short - term prices are expected to be weakly adjusted, and subsequent attention should be paid to changes in coal and oil prices [139]. 3.
