Report Industry Investment Rating - Not provided in the content Core Viewpoints - The short - term supply and demand of PTA are acceptable, but the external market fluctuates greatly, and the valuation drive is weak, with the technical side showing range - bound fluctuations. The cost of crude oil has been falling continuously, and attention should be paid to the support at the lower edge of the range. TA processing fees continue to weaken, and the losses of downstream products have improved. It is recommended to focus on trading in the 4600 - 4800 range of the 2601 contract [4] Summary by Directory Supply - Last week, the average weekly PTA capacity utilization rate was 76.10%, a decrease of 3.57 percentage points from the previous week and 2.26 percentage points from the same period last year, at a neutral level in the same period. Multiple sets of equipment in the East China region had short - term outages or maintenance, and some enterprises reduced their loads due to efficiency issues, leading to a decrease in the operating rate [4][18] - Last week, PTA production was 136,840 tons, a decrease of 4.03% from the previous week and an increase of 1.66% from the same period last year. From January to June 2025, China's cumulative PTA imports were 14,130 tons, a year - on - year increase of 84.61%. With the gradual increase in domestic self - sufficiency, imports are relatively low and can be basically ignored [22] Demand - In July 2025, the actual PTA consumption was 5.9785 million tons, a month - on - month increase of 0.28% and a year - on - year increase of 8.78%.

Downstream texturing and terminal weaving factories have a strong cautious and wait - and - see attitude, mainly consuming their previous raw material inventories. The sales data of polyester filament have been in a sluggish state [4][26] - From January to June 2025, the cumulative PTA export volume was 1.8568 million tons, a year - on - year decrease of 16.90%.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Short - fiber (PF): In the short - term, it is in a volatile market with limited downside space. In the medium - term, it is weak. The demand is expected to improve in mid - to late August, and the processing fee is expected to expand as the peak season approaches [7]. - Bottle chips (PR): In the short - term, the downside space is limited, and there may be a stable rebound. In the medium - term, the pressure is still obvious. There is a de - stocking pattern from July to August, but there are pressure factors after the end of production cuts and during the peak season [8][9]. 3. Summary by Relevant Catalogs 3.1 Short - fiber (PF) 3.1.1 Valuation and Profit - Spot fluctuations are small, the futures market is weak, and the basis has strengthened slightly. The futures processing fee is still weak [101][106]. - The current spot processing fee is 900 - 1000 yuan/ton, and a processing fee below 900 yuan/ton is considered undervalued [7]. 3.1.2 Fundamental Operation - **Supply**: Based on low processing fees and inventory pressure, factories maintain high - level production. The average factory operating rate this week is 90.6%, and the operating rate of direct - spinning polyester staple fiber for spinning is 95.3%. It is expected to remain stable or increase slightly in the future [7]. - **Demand**: The terminal weaving operating rate has bottomed out and is rising. Short - term demand is still weak, but there is replenishment at low prices. The 1.4D equity inventory is 10.6 days, and the physical inventory is 23 days. Sino - US trade negotiations may lead to an increase in foreign trade orders after the new round of tariffs is implemented in August [7]. 3.1.3 Strategy - **Single - side**: None - **Inter - period**: None - **Inter - variety**: Go long on PF and short on PR when the spread is below 450 [7] 3.2 Bottle chips (PR) 3.2.1 Valuation and Profit - The spot processing fee has strengthened to 400 - 450 yuan/ton, which is relatively reasonable. There is increasing demand for short - covering or speculative purchases when the price is below 4900 yuan/ton [10]. - Aggregate costs have decreased, and export profits are fluctuating weakly [50]. 3.2.2 Fundamental Operation - **Supply**: After this round of production cuts, the processing fee has not risen above the factory cost. Factories are expected to maintain the current production - cut intensity until the end of August and gradually resume production in September, but may still maintain partial production cuts. The operating rate this week is 79% [8]. - **Demand**: Domestic downstream operating rates remain high, and there is restocking at low prices. Ocean freight has declined, and the impact on exports from July to August has decreased. There is a slight de - stocking pattern from July to August, and the factory inventory is about 17 days this week, showing a month - on - month decrease [8][9]. 3.2.3 Strategy - **Single - side**: None - **Inter - period**: Go long on the 10 - 11 or 10 - 12 spreads at low prices - **Inter - variety**: Go long on PF and short on PR at low prices [11] 3.2.4 Other Aspects - **"Anti - involution" Impact**: It mainly leads to potential cost increases, and has little impact on supply as most bottle - chip devices are less than 10 years old [14]. - **Base and Spread**: The emotional premium has declined, and the basis is strongly volatile [24]. - **Price and Spread**: The price has slightly decreased this week, with the domestic price at 5920 - 5950 yuan/ton and the FOB price at 770 - 795 US dollars/ton. The substitution relationship with PVC and PP shows different characteristics [27][30][31]. - **Production and Operation Rate**: Since 2024, the production capacity has been expanding, and the current effective production capacity is 2.168 million tons. This week, the bottle - chip load has remained at 79.3%, and the weekly production is still at a high level on a month - on - month basis [35]. - **Raw Material Operation**: There are new PTA device overhauls, and MEG has also shown certain operating characteristics [42][49]. - **Cost and Profit**: Aggregate costs have decreased, the bottle - chip spot processing fee has been repaired, and export profits are fluctuating weakly [50]. - **Inventory**: The overall PTA inventory of polyester factories has decreased, and the domestic polyester bottle - chip factory inventory has dropped to 17 days. There is a de - stocking pattern of social inventory from July to August [55][60]. - **Device Changes**: The production - cut expectation has been extended. Some factories plan to restart in September, and there are also new device investment plans [61]. - **Demand**: Downstream operating rates are at a high level and slightly increasing. Beverage consumption from January to June 2025 is relatively weak year - on - year, but there are new production lines being put into operation. Edible oil demand remains neutral, and sheet demand is average, but supermarket consumption has improved month - on - month [64][70][73][76]. - **Global Trade Flow**: Overseas bottle - chip production capacity has little growth, and China's bottle - chip exports have multiple trade flows [80]. - **Export Situation**: In June 2025, the total export volume of polyester bottle chips and slices was 657,000 tons, a year - on - year increase of 6.5%. The short - term is affected by ocean freight, but the trend is strong [83]. - **Anti - Dumping Policy**: Multiple countries have implemented anti - dumping policies on Chinese bottle chips [94]. - **Supply - Demand Balance Sheet**: There is a tight balance from July to August, and inventory will accumulate again after September [95].
