Core Viewpoint - The polyester sector has experienced a rebound since August 15, driven by multiple factors including stable oil and coal prices, low inventory levels of key raw materials, and an approaching demand peak season [1][2]. Group 1: Market Dynamics - The recent price increase in the polyester sector is supported by stable oil and coal prices, which have rebounded, and the sector's long-term low valuation limits further downside potential [1]. - The inventory levels of key raw materials such as PX, PTA, and MEG are currently low, which, combined with the upcoming demand peak season, provides strong upward price elasticity if unexpected positive factors arise [1]. - The demand side is transitioning from a low to a high season, with weaving operating rates recovering to 63% and polyester operating rates increasing to 89.4% [2]. Group 2: Supply Chain Insights - The polyester industry is currently in a phase of orderly expansion, with upstream production of PX and short fibers being paused, while PTA and bottle-grade PET continue to see rapid capacity growth [2][3]. - The overall profit levels in the polyester supply chain remain low, with profits concentrating in the upstream due to differing production rhythms across the supply chain [2][3]. Group 3: Future Outlook - The current trading logic in the polyester sector reflects a contradiction between strong realities and weak expectations, with concerns about demand being dragged down by earlier "export rush" activities [3]. - Short-term expectations suggest that the polyester sector may experience a pattern of easy price increases but difficult declines, while long-term price strength will depend on cost stability, supply-demand dynamics, and macroeconomic sentiment [3]. - Analysts predict a generally strong price trend for polyester until September, with a focus on valuation changes and the actual impact of supply-side factors thereafter [3].

Core Viewpoint - The PTA industry is experiencing tight supply and low processing fees, with expectations for a price rebound due to cost support and supply-demand improvements [1][5]. Group 1: PTA Production and Supply - As of early August, domestic PTA processing fees dropped to a historical low of 126 CNY/ton, recently recovering to around 200 CNY/ton, but still low [2]. - The production cost of PTA is approximately 4500 CNY/ton, with companies facing a loss of about 265 CNY/ton [2]. - Domestic PTA production enterprises have shown some operational resilience, with several plants undergoing maintenance and restarts, leading to a slight increase in operating rates [2]. - As of August 20, the operating load of domestic PTA production enterprises was 78.62%, down 4.47 percentage points year-on-year, with a production volume of around 1.38 million tons and a demand of approximately 1.42 million tons, resulting in a supply gap of about 35,000 tons [2]. Group 2: PTA Inventory and Market Conditions - Due to the supply gap, domestic PTA inventory is declining, with social inventory at 3.6952 million tons as of August 15, down 36,300 tons week-on-week and 0.97% lower year-on-year [3]. - Factory inventory of PTA is at 3.66 days, down 0.16 days year-on-year, while polyester factory PTA raw material inventory is at 7.15 days, down 1.06 days year-on-year [3]. Group 3: Polyester Industry and Demand - The polyester industry is currently in a loss state, but conditions have improved, particularly for polyester filament, which has moved from a loss of 200-300 CNY/ton to a near breakeven point [4]. - As of August 20, the operating load of the domestic polyester industry was 86.46%, down 2.83 percentage points year-on-year, with expectations for a slight increase in operating rates due to recent improvements [4]. - Polyester long filament inventory remains high, with significant de-stocking pressure; however, recent price reductions by some polyester companies have led to a decrease in inventory levels [4]. Group 4: Overall Market Outlook - Overall, the PTA supply is tight, production companies are facing increased losses, and there is a demand for price rebound. The processing fees are low and need to be repaired, while the supply side shows lower operating loads and declining inventories, indicating a potential for price rebound supported by costs [5].

Its price is expected to be strong in the short - term, with an easy - to - rise and hard - to - fall trend. The operation strategy is to buy on dips close to the cost end. In the medium - to - long - term, the prosperity of the downstream polyester peak season needs to be observed, and long positions can be hedged by selling near - month out - of - the - money call options [3]. 3. Summary According to Related Catalogs 3.1 Polyester Price Range Forecast | Product | Price Range (Monthly) | Current Volatility (20 - day Rolling) | Current Volatility Historical Percentile (3 years) | | ---- | ---- | ---- | ---- | | Ethylene Glycol | 4200 - 4700 | 9.09% | 1.4% | | PX | 6500 - 7400 | 11.78% | 17.7% | | PTA | 4400 - 5300 | 9.30% | 4.6% | | Bottle Chips | 5800 - 6500 | 7.92% | 0.9% | [2] 3.2 Polyester Hedging Strategy Table - **Inventory Management**: When the finished - product inventory is high and worried about the decline of ethylene glycol price, for long - position spot exposure, sell EG2601 futures with a 25% hedging ratio at 4500 - 4600, buy EG2510P4350 put options, and sell EG2510C4600 call options with a 50% hedging ratio at 30 - 50 to lock in profits and reduce costs [2]. - **Procurement Management**: When the regular procurement inventory is low and procurement is based on orders, for short - position spot exposure, buy EG2601 futures with a 50% hedging ratio at 4250 - 4350, and sell EG2510P4350 put options with a 75% hedging ratio at 30 - 50 to lock in procurement costs and reduce costs [2]. 3.3 Logic Analysis - Ethylene glycol is in a weak supply - demand balance with limited inventory accumulation, and the inventory accumulation expectation has been fully priced. Once there is an unexpected change in supply - demand, it may rebound rapidly [4]. - The coal - based profit of ethylene glycol is compressed by coal prices, and the downward space is limited under stable costs [4]. - The ethylene glycol plants are operating at full capacity, and additional supply is difficult to increase even if the valuation rebounds. Supply losses are difficult to replenish quickly in case of supply accidents [6]. 3.4利多解读 (Likely to be "Positive Factors Analysis" in English) - South Korea plans to cut up to 3.7 million tons of naphtha cracking capacity annually, which may impact the raw material supply and ethylene - based cost of ethylene glycol, pushing up its price [7]. - The planned arrival at the port this week is 965,000 tons, relatively low, and the port inventory is expected to decrease by about 30,000 tons next Monday, tightening spot liquidity [7]. - The load of looms and spinning mills has increased slightly. With the approaching of September, some autumn - winter orders at the terminal have started, which is expected to drive order release and increase the load of filament yarns [7]. - The price of thermal coal has strengthened slightly, further compressing coal - based profits and strengthening cost support [7]. 3.5利空解读 (Likely to be "Negative Factors Analysis" in English) - The total load of ethylene glycol has dropped to 66.39% (- 2.01%), with a decrease in oil - based production and an increase in coal - based production.

With the recent improvement in sales and inventory reduction, and the recovery of PTA price, the load of the weaving end increased slightly [2]. - Ethylene Glycol (MEG): Coal prices recovered, and MEG prices also recovered. The macro - sentiment weakened slightly, and the chemical industry followed the weakening sentiment of commodities. Overseas MEG plant maintenance, especially in Saudi Arabia, was continuously postponed, which might have a significant impact on the market outlook and boosted MEG prices. The later arrival volume of MEG decreased.
