Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report - In 2026, PX's new capacity pressure is expected to gradually emerge in the second half of the third quarter. PTA is in a production hiatus, and PX is expected to remain strong in the industrial chain. PTA may have a recovery expectation after its processing fee hits a recent low. The supply - demand pressure for the whole year is not significant. Pay attention to the opportunity for PTA processing fee to recover and the opportunity for the spread between TA - EG to widen on dips [1][163]. - In 2026, ethylene glycol (MEG) faces significant production pressure. Potential capacity and high overseas supply pose risks to the market. Overall, the supply - demand pattern of MEG is weaker than that of PTA. Pay attention to the spread changes [1][163]. - In 2026, due to the continued slowdown of global economic growth, domestic demand is weak and requires more policy support. Exports may continue to be mainly for rigid demand. Despite the pressure on terminal exports, polyester segment exports are still worth looking forward to. The polyester segment will continue to grow steadily. The supply - demand pressure in the staple fiber market is expected to increase, and attention should be paid to the opportunity to protect processing fees at high prices. The new supply pressure of bottle chips in 2026 is not large, but the capacity of existing devices is still high. Overall profit may have an improvement expectation, but the recovery space may not be optimistic [2][164]. Summary According to Relevant Catalogs 1. Market Review - **PTA**: In 2025, PTA reached a high of around 5300 yuan/ton at the beginning of the year. The market price declined due to seasonal inventory accumulation and tariff increases. The new device put into operation in the second half of the year put pressure on the market, and the main contract price fluctuated widely between 4400 - 5000 yuan/ton. Three new devices were put into operation, with a net capacity growth rate of 7.1%, and the cumulative output was expected to be 7390 tons, a year - on - year increase of about 2.8% [19][23]. - **MEG**: In 2025, the futures price of ethylene glycol showed a phased downward trend. Three new devices with a total of 170 tons were put into operation, with a net capacity growth rate of 3.7%. The cumulative output was expected to be 2080 tons, a year - on - year increase of 6.1% [23]. - **Polyester and Terminal**: In 2025, the domestic sales growth of textile and apparel was slow. Exports were volatile, with a significant decline in exports to the US. The polyester segment had good production but poor profits due to raw materials and demand. The cumulative new capacity of polyester in the whole year was expected to be 446 tons, and the cumulative output from January to December was expected to be 7990 tons, with a year - on - year growth rate of about 6.8% [24]. 2. PTA: More Maintenance under Low Processing Fees, with Expectation of Supply - Demand Improvement - **Raw Material End**: From 2024 - 2025, there was no new PX production capacity. The average operating rate in 2025 was 82.8%, and the estimated output was 3.84 billion tons, a year - on - year increase of 1.6%. In 2026, new production capacity is mainly planned to be put into operation in the second half of the year, and PX is expected to remain strong in the industrial chain [30][37]. - **Processing Fee**: In 2025, the average spot processing fee of PTA was only 262 yuan/ton, the lowest in recent years. In the second half of the year, the processing fee fell below 200 yuan/ton, leading to more maintenance [39][45]. - **Export**: In 2025, from January to October, China's PTA exports totaled 3.096 million tons. The cancellation of India's BIS certification is beneficial to exports, but the future new production capacity in India may affect exports [45]. - **2026 Outlook**: There is no new PTA production plan in 2026. The supply - demand situation is expected to improve. Pay attention to the opportunity for PTA processing fees to recover [47]. 3. MEG: Supply Pressure is Prominent - **Actual Supply Increase**: In 2025, the price of ethylene glycol dropped significantly twice, and the end - of - year futures price hit a five - year low. The actual output increased significantly. The proportion of naphtha - based MEG is still about half, and the proportion of coal - based ethylene glycol is about 36% [50]. - **Cash Flow and Operating Rate**: In 2025, the average cash flow of naphtha - based MEG was - 120 US dollars/ton. The overall domestic ethylene glycol operating rate was 70.6%. The coal - based ethylene glycol operating rate was relatively high, and the profit situation improved significantly [64][65]. - **Inventory and Import**: In 2025, the main port inventory first increased and then decreased, and then increased again at the end of the year. From January to October, the import volume was 6.3 million tons, a year - on - year increase of 16.2%. The overseas supply is generally abundant, and imports are expected to remain at a relatively high level [70]. - **Future New Production**: From 2026, the planned production capacity of ethylene glycol will increase again. The future supply - demand pattern is weaker than that of PTA. Pay attention to the spread between PTA - MEG [72][73]. 4. Demand: Polyester Shows Resilience, Pay Attention to Policy Changes in the Terminal - **Polyester Growth**: In 2025, it is expected that a total of 4.46 million tons of new polyester production capacity will be put into operation. The average operating load for the whole year reached 90%. The expected output for the whole year was about 79.8 million tons, a year - on - year increase of 6.8%. In 2026, the planned new polyester production capacity is 5 - 6 million tons, and the output is still expected to reach about 85 million tons [86][100]. - **Staple Fiber**: In 2025, the effective production capacity of direct - spun polyester staple fiber increased by about 4%, and the output increased by 10.1%. The inventory decreased to a low level, and the average operating rate was 91%. In 2026, the supply - demand pressure in the staple fiber market is expected to increase. Pay attention to the opportunity to protect processing fees at high prices [106][122]. - **Bottle Chips**: In 2025, the new production scale of bottle chips narrowed, and the average spot processing fee dropped to a record low of 386 yuan/ton. The inventory pressure was transferred in the third quarter, and the inventory accumulation slowed down in the fourth quarter. In 2026, the new supply pressure is not large, and the profit may improve, but the recovery space may not be optimistic [125][134]. - **Terminal Market**: In 2025, the domestic demand for textile and apparel improved moderately, and exports were affected by international trade. In 2026, domestic demand is weak and requires policy support, and exports may be mainly for rigid demand. Polyester segment exports are still worth looking forward to [141][162]. 5. 2026 Market Outlook and Strategies - **PTA**: In 2026, PX's new capacity pressure is expected to gradually emerge in the second half of the third quarter. PTA may see its processing fee recover, and the supply - demand pressure for the whole year is not significant. Pay attention to the opportunity for PTA processing fee to recover and the opportunity for the spread between TA - EG to widen on dips [1][163]. - **MEG**: In 2026, the production pressure of ethylene glycol is large. The inventory may continue to rise at the beginning of the year, improve in the second quarter, and enter the inventory accumulation cycle again in the third and fourth quarters. The supply - demand pattern is weaker than that of PTA. Pay attention to the spread changes [1][163]. - **Polyester and Terminal**: In 2026, domestic demand is weak and requires policy support. Exports may be mainly for rigid demand. The polyester segment will continue to grow steadily. The supply - demand pressure in the staple fiber market is expected to increase, and the profit of bottle chips may improve, but the recovery space may not be optimistic [2][164].

Core View of the Report The report comprehensively analyzes the PTA, MEG, and downstream polyester industries, covering their basic knowledge, production, trade, and market conditions. It highlights the high concentration of PTA and MEG production in Asia, especially in China, and the significant growth in domestic production capacity in recent years. The report also discusses the trade patterns, profit situations, and market trends of these industries [12][24][43]. 3. Summary by Directory PTA Basics - **Definition and Market Introduction**: PTA, or purified terephthalic acid, was the first chemical futures variety listed in China in December 2006. It is a raw material for polyester with end - uses mainly in textile, clothing, and soft drinks [12]. - **Storage and Transportation**: Mainly stored in packaging bags at East China's main port terminals, with storage areas along the Yangtze River, Hangzhou Bay, and Xiamen. Transportation is mainly by sea and inland waterways, with some short - distance transportation by road [14]. - **Industry Chain**: Produced from crude oil via PX, it is mainly used to produce polyester (PET). One ton of PET requires 0.855 tons of PTA and 0.332 tons of MEG. About 70% of PTA is used for polyester fibers, 24% for bottle - grade polyester, and the rest for film - grade polyester [19][20]. - **Production Capacity**: Global PTA capacity is mainly in Asia (nearly 90%), with China accounting for over 78% of Asia's capacity. As of November 2025, China's effective PTA capacity reached 9471.5 million tons [24]. - **Capacity Distribution**: Regionally concentrated in Jiangsu and Zhejiang, with private enterprises being the main suppliers. Yisheng and Hengli account for 41% of the total capacity [27][28]. - **Import and Export**: China's PTA imports have decreased from 2.74 million tons in 2013 to 18,000 tons in 2024, while exports reached 4.42 million tons in 2024, mainly to other Asian regions and Russia [31]. - **Profit Situation**: From 2016 - 2019, the industry had high profits due to limited new capacity and downstream recovery. From 2020 - 2024, private large - scale refineries' concentrated production led to compressed processing fees and the elimination of some high - cost small - scale plants [36]. - **Trading Patterns**: Include long - term contracts (referencing CCF's daily average price with appropriate premiums/discounts), spot trading (futures + price - fixing), and derivative pricing methods (futures price - fixing + monthly/weekly average basis) [38]. MEG Basics - **Definition and Application**: Ethylene glycol (MEG) is an important petrochemical raw material, mainly used in polyester production. Globally, about 85% of MEG is used in polyester, while in China, over 93% is used in polyester [43]. - **Production Process**: The main synthesis routes are the ethylene route (including petroleum ethylene, ethane ethylene, and MTO ethylene methods) and the oxalate route. The ethylene method is the global mainstream, while China mainly uses the petroleum ethylene method and the coal - to - ethylene glycol oxalate method [50][51]. - **Profitability of Different Processes**: Coal - to - MEG's profit has improved significantly this year, with higher operating loads. Ethylene - based MEG has been operating below the break - even point, but losses have narrowed compared to the previous two years [54]. - **Production Capacity Development**: China's MEG production capacity has reached 30.075 million tons, with ethylene - based capacity accounting for about 64% and coal - based capacity accounting for 36% [58][62]. - **Production Distribution**: Ethylene - based plants are mainly in Zhejiang, Jiangsu, and Liaoning, while coal - based plants are in Shaanxi, Xinjiang, and Inner Mongolia [62]. - **Import and Export**: MEG imports peaked in 2020 and have since declined. In 2024, the import dependence dropped to 25%, with the main import sources being Saudi Arabia, Canada, and the United States [65]. Downstream Polyester Basics - **PTA/MEG's Downstream Products**: The main downstream demand for PTA/MEG is polyester, which is used in textile, clothing, beverages, and film products. Filament has the largest share in polyester, followed by short - fiber and bottle - chips [69]. - **Short - Fiber Basics**: Polyester short - fiber is made from PTA and MEG. Its trade pattern is mainly from east to west and bidirectional north - south. The main production and sales areas are Jiangsu, Fujian, and Zhejiang, with transportation mainly by road, water, and rail [71][76][77]. - **Short - Fiber Industry Chain**: It is produced from crude oil via PTA and MEG, with end - uses in filling, non - woven, and spinning. In 2024, spinning accounted for 64% of direct - spun polyester short - fiber production [79]. - **Short - Fiber Production Capacity Distribution**: Concentrated in Jiangsu and Zhejiang. In recent years, short - fiber exports have increased significantly, with 1.318 million tons exported in 2024, a 9.4% increase year - on - year, and 1.255 million tons exported from January - September 2025, a 31% increase year - on - year [83][88]. - **Polyester Bottle - Chips Basics**: Made from PTA and MEG, used mainly for packaging. Sales are divided into direct sales (60% - 70%) and distribution (30% - 40%) [91][102]. - **Bottle - Chips Production Capacity**: Production capacity has increased rapidly, exceeding 20 million tons at the end of 2024, almost doubling since the end of 2022 [105]. - **Bottle - Chips Demand**: Global demand has been growing steadily, with an average annual growth rate of 6.1% from 2015 - 2024. In 2024, the main downstream consumption areas were soft drinks (39%), exports (42.4%), sheet materials (15.8%), and oil bottles (2.9%) [108]. - **Bottle - Chips Export Trade**: China is the world's largest net exporter, with exports widely distributed. In 2024, the top five export destinations accounted for only 23% of total exports [112][113].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In the off - season of demand and with low valuations, there is no need to chase short positions in the short term. For PX, supply continues to shrink, and the unilateral price rebounds. For PTA, the cost is supported, but the monthly spread is under pressure, with the unilateral price oscillating slightly stronger. For MEG, the unilateral price oscillates stably, and the strategy of going long on PTA and short on MEG should be closed [3][4]. 3. Summary by Relevant Catalogs 3.1 PX 3.1.1 Valuation and Profit - The volatility of the unilateral price comes from crude oil. In July, the supply - demand of PX remains tight, and it is advisable to go long on the monthly spread at low prices. The PXN strengthens, and the gasoline cracking spread also strengthens, improving the refinery's enthusiasm for starting operations. The toluene disproportionation profit continues to rise, while the toluene chemical economy weakens month - on - month, and the MX chemical economy rebounds month - on - month [18][22][30]. 3.1.2 Supply, Demand, and Inventory - The load of CICC Petrochemical decreases, and the PX load slightly drops. In July, attention should be paid to the maintenance plans of Tianjin Petrochemical and Zhejiang Petrochemical. In May, the domestic PX output increased to 2.97 million tons, and the weekly operating rate was 83.8% (- 1.8%). The apparent consumption in May was 3.55 million tons. In May, the import volume increased to 773,000 tons month - on - month. The Asian PX device operating rate this week was 74.3% (- 1.3%). In May, the Longzhong PX monthly inventory decreased to 4.51 million tons [53][55][62][79]. 3.2 PTA 3.2.1 Valuation and Profit - The TA device load increases, and the volume of credit warehouse receipts increases at high prices. The cost rises, the PX profit decreases, and the PTA profit remains at a low level. The 9 - 1 monthly spread around 200 yuan is recommended to be closed or appropriately reverse - arbitraged [89][96][95]. 3.2.2 Supply, Demand, and Inventory - The de - stocking intensity narrows, and this week may turn into a stocking pattern. In May, the PTA output was 5.91 million tons, a 1% increase month - on - month. The container freight rate drops, which is beneficial for exports. In May, the export volume was 270,000 tons, a significant decrease. The social inventory is 2.16 million tons (- 40,000 tons), the de - stocking slope slows down, and it will gradually turn into a stocking pattern in July [99][101][108][122]. 3.3 MEG 3.3.1 Valuation and Profit - With the return of Iranian supply and weakening demand, the monthly spread and basis drop significantly. The seasonal demand for ethylene oxide decreases, and attention should be paid to the conversion of production. The profits of coal - based, MTO, and ethylene - purchased MEG production decline from high levels, while the profit of naphtha - based MEG production recovers [130][134][136]. 3.3.2 Supply, Demand, and Inventory - The device operating rate drops. In May, the ethylene glycol import volume was 600,000 tons, and the import from the Middle East decreased. The impact of the Middle East geopolitical conflict on ethylene glycol imports may be reflected in August. The import profit decreases month - on - month, which may affect the June imports. The port continues to de - stock, and the import volume will continue to increase to 110,000 - 120,000 tons next week [144][146][151][156]. 3.4 Polyester 3.4.1 Valuation and Profit No relevant content provided. 3.4.2 Supply, Demand, and Inventory - The polyester operating rate is 91.2% (- 0.8%). Multiple polyester devices reduce production, and the overall load will drop to 89.3%. The polyester output increases by 8% year - on - year. This week, the sales are sluggish, and the downstream enters the off - season [160][163][166][168].

Group 1: Report Investment Rating - No investment rating information provided Group 2: Core Views - This week, the geopolitical conflict in the Middle East intensified, causing a significant increase in crude oil prices and a notable upward push on the cost side. Due to the war, some ethylene glycol plants in Iran temporarily shut down, leading to concerns about supply losses and a continuous upward trend in ethylene glycol prices [1]. - The overall operating load of ethylene glycol in mainland China is 70.33% (a 4.07% increase from last week), with the operating load of ethylene glycol produced by oxalic acid catalytic hydrogenation (syngas) at 70.16% (a 1.73% increase from last week). Domestic supply is expected to increase as the maintenance period ends, and the load will return to a high level in July. Although Iranian ethylene glycol plants have temporarily shut down, inventory is still being shipped normally, with little impact on actual arrivals in July. The supply situation from August to September depends on the shutdown duration and shipping routes [1]. - The operating load of textile looms in Jiangsu and Zhejiang is 65.0% (a 2.0% decrease from last week), and the operating load of texturing machines is 77.0% (a 2.0% decrease from last week). The polyester operating rate is 92.00% (a 1.10% increase from last week), and the direct - spun filament load is 91.40% (a 1.20% increase from last week). The inventory days of POY, FDY, and DTY have all increased. The operating rate of polyester staple fiber plants is 95.1% (+3.0%), and the equity inventory days are 12.1 days (a 0.6 - day increase from last week). The operating rate of bottle - chip plants is 80.7% (a 0.9% increase from last week). Domestic and foreign sales are in the off - season, with terminal orders and operations declining. However, polyester performance is relatively good, and the load is firm. After the raw material price increase, filament inventory decreased due to concentrated restocking. This week, the filament and bottle - chip loads increased. High - price fluctuations may increase inventory pressure, and continued attention should be paid to polyester inventory changes. In the short term, the filament load is expected to remain stable. The inventory of staple fiber is not high, and the implementation of production cuts is uncertain. Regarding bottle chips, Wankai Yisheng plans to start maintenance at the beginning of July, and Huarun plans to start on June 22, involving a production capacity of 2.36 million tons. Attention should be paid to the actual implementation [2]. - According to CCF data released every Monday, the inventory of MEG at the main ports in East China is 616,000 tons (a decrease of 18,000 tons from last week); according to Longzhong data released every Thursday, the inventory is 537,000 tons (a decrease of 27,000 tons from last week). The planned arrivals at East China ports this week total 100,000 tons, which is neutral, and port inventory is expected to remain stable. Attention should be paid to changes in arrival schedules due to the shutdown of Iranian plants [3]. - On the supply side, domestic supply is gradually recovering. The supply - demand structure in June still shows a favorable inventory reduction, but after the warehouse receipts are cancelled and flow out, the available spot in the market will increase. The load will return to a high level in July. Overseas, although Iranian ethylene glycol plants have temporarily shut down, inventory is still being shipped normally, with little impact on actual arrivals in July. The supply situation from August to September depends on the shutdown duration and shipping routes. Later, the recovery of domestic production and the increase in Saudi supply will largely offset the impact of the shutdown of Iranian plants. On the demand side, the current situation is firm, but several major bottle - chip manufacturers have concentrated maintenance plans at the end of June and beginning of July, and the demand outlook is weak. Attention should be paid to the actual implementation [3]. - For trading strategies, the short - term outlook is bullish. Attention should be paid to further developments in the Middle East geopolitical conflict, and if the conflict eases, prices may fall. There are no cross - period or cross - variety strategies [4]. Group 3: Summary by Directory Price and Spread - This week, the geopolitical conflict in the Middle East intensified, causing a significant increase in crude oil prices and a notable upward push on the cost side. Due to the war, some ethylene glycol plants in Iran temporarily shut down, leading to concerns about supply losses and a continuous upward trend in ethylene glycol prices [1] Supply - The overall operating load of ethylene glycol in mainland China is 70.33% (a 4.07% increase from last week), with the operating load of ethylene glycol produced by oxalic acid catalytic hydrogenation (syngas) at 70.16% (a 1.73% increase from last week).
