Report Information - Report Title: Soda Ash and Glass Weekly Report - 2025.10.20 [1] - Author: Shen Wen [2] - Report Source: Research and Consulting Department of Zhongyuan Futures [1] 1. Investment Ratings - No investment ratings for the industry are provided in the report. 2. Core Views 2.1 Soda Ash - This week, the spot price of soda ash remained stable. Supply decreased due to maintenance, but is expected to increase as previously maintained units resume production. Demand is weak, with some enterprises having poor shipping and a slight accumulation of alkali plant inventory. High supply and inventory strongly suppress soda ash prices, and the futures price continues to fluctuate weakly. In the medium to long term, there is still pressure of loose supply and demand under the pattern of new capacity release. Opportunities for shorting on rebounds after the weakening of macro - disturbances can be considered. The SA2601 contract is expected to operate in the range of 1150 - 1300 yuan/ton [5]. 2.2 Glass - This week, the spot price of float glass fluctuated. The overall supply was stable, while demand was weak, leading to a continuous increase in inventory. The futures price may continue to be weak. Attention should be paid to the cold - repair dynamics of production lines under the condition of profit losses [6]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report 2.1 Weekly Summary - PX prices declined during the week due to lack of cost support. International oil prices dropped continuously because of signs of easing geopolitical conflicts and Sino - US trade frictions. Domestic PX开工 was at a high level for the year, and although there was a fire at a South Korean refinery, the PX device was not affected. Downstream demand did not improve significantly, leading to a price decline under weak cost and fundamentals [9]. - PTA prices also fell during the week due to the lack of cost support and the expectation of new device commissioning. The weakness of crude oil and PX negatively affected the PTA market sentiment. The potential trial - run of 2.7 million tons of new PTA production capacity in East China would increase the supply pressure. Although downstream开工 increased driven by the demand for warm - keeping products, the subsequent upward space was limited, and the fundamental boost to PTA was weakening [9]. 2.2 Market Forecast - Crude oil prices will fluctuate within a narrow range, waiting for the follow - up development of Sino - US trade issues. - For PX, due to sanctions, trade wars and other factors, the short - term production of some factories may be affected, thus affecting PX supply, but the overall开工 will remain at a high level. - For PTA, PTA factories have not further reduced production even under low - efficiency conditions, and the expectation of new device commissioning in East China suppresses market sentiment. It is expected that the开工 will remain at a high level. - For polyester, the polyester开工 load will be generally stable, and there are no planned start - up or shutdowns of polyester devices. At the end of the traditional peak demand season, it is estimated that polyester factories will not actively reduce production to maintain market share. - For the weaving industry, foreign customers are conservative in placing orders due to uncertain factors, resulting in slow placement of recent export orders. Domestic demand has increased, but factories are not optimistic about the subsequent market. - Overall, PX will operate weakly in the range of 6,150 - 6,350 yuan/ton; PTA will also operate weakly in the range of 4,300 - 4,500 yuan/ton. The recommended strategy is to stay on the sidelines [10]. 3. Summary by Relevant Catalogs 3.1 Price Situation 3.1.1 PX - **Futures**: On October 17, the closing price of the PX main contract was 6,292 yuan/ton, down 212 yuan/ton from October 10, a change of - 3.26%. The settlement price on October 17 was 6,334 yuan/ton, down 198 yuan/ton from October 10, a change of - 3.03% [14]. - **Spot**: The market negotiation and trading atmosphere were acceptable, with a differentiated trend in the paper - spot market. From October 13 - 17, the average basis of the main contract was - 131 yuan/ton; the average domestic PX spot price was 6,250 yuan/ton, a decrease of 125.50 yuan/ton from the previous period, a change of - 1.97% [15][17]. 3.1.2 PTA - **Futures**: The price decline was dominated by cost. On October 17, the closing price of the PTA main contract was 4,402 yuan/ton, down 132 yuan/ton from October 10, a change of - 2.91%. The settlement price on October 17 was 4,424 yuan/ton, down 130 yuan/ton from October 10, a change of - 2.85% [19][21]. - **Spot**: The negotiation atmosphere was average, mainly among traders, with individual polyester factories making inquiries. There was concentrated trading on Friday, with an average daily trading volume of about 2 - 3 million tons. From October 13 - 17, the average basis of the main contract was - 70 yuan/ton. The weekly average CIF price of PTA in the Chinese market was 549.2 US dollars/ton, down 17.8 US dollars/ton from the previous period, a change of - 3.13%. The average spot price of PTA in the East China market was 4,371.6 yuan/ton, down 108.07 yuan/ton from the previous period, a change of - 2.41% [22][24]. 3.2 Device Operation Situation 3.2.1 PX Devices - There were changes in the operation of PX devices in different regions. For example, in East China, some enterprises such as Ningbo Daxie, Sheng Hong Refining and Chemical, and Zhejiang Petrochemical had different load - operation conditions. In North China, Urumqi Petrochemical stopped for maintenance on October 14, expected to last for 15 days. The overall domestic PX开工 rate remained at a high level, and the planned maintenance of domestic and foreign PX devices in the fourth quarter was limited [29][33]. 3.2.2 PTA Devices - Some large - scale PTA devices were under maintenance, such as those of Ningbo Taihua, Hainan Yisheng, and Yisheng Dahua. The weekly开工 rate decreased by 1.92% [36][37]. 3.3 Fundamental Analysis 3.3.1 Cost - **Crude Oil**: European and American crude oil futures fell for three consecutive weeks, with a cumulative decline of more than 12%. The WTI crude oil futures settlement price on October 17 was 57.15 US dollars/barrel, down 1.75 US dollars/barrel from October 10. The Brent crude oil futures settlement price on October 17 was 61.29 US dollars/barrel, down 1.44 US dollars/barrel from October 10. The market was concerned about the resolution of the Russia - Ukraine conflict, and the price was affected by factors such as trade relations, supply and demand expectations, and geopolitical situations [42][44]. - **Naphtha**: The price continued to decline this week, and the economy rebounded slightly. The weekly average CFR price of naphtha in Japan was 550.25 US dollars/ton, and the weekly average production profit was 60.72 US dollars/ton. The fundamental situation of naphtha did not change significantly, and the East - West arbitrage window remained open, with European naphtha flowing to Asia. The substitution effect of downstream LPG on naphtha affected some demand expectations, and the subsequent impact of sanctions and trade wars on naphtha remained to be evaluated [47][49]. 3.3.2 Supply - **PX Processing Margin**: The PXN margin rebounded slightly, and the short - process efficiency narrowed. The weekly average PXN was 236.92 US dollars/ton, a change of 7.36% from the previous period. The PX - MX margin remained at a high level, with a weekly average of 98.75 US dollars/ton. Due to the high domestic开工 rate and insufficient demand, the decline of PX was obvious, and the cash flow continued to narrow during the week, with short - process devices near the break - even point [50][52]. - **PTA Processing Fee**: The boost of device short - stops to the processing fee was limited. From October 13 - 17, the average spot processing fee of PTA was 169.05 yuan/ton, compared with 202.90 yuan/ton last week. Although the production reduction plan temporarily increased the processing fee, the demand did not improve significantly, and it was difficult to improve the processing fee under weak cost and demand [54][56]. - **Inventory**: As of October 16, the PTA social inventory was 4.126 million tons, a decrease of 72,000 tons from the previous week, a change of - 0.47% in the month - on - month growth rate. The decrease in inventory was due to device maintenance rather than demand improvement. The inventory days of PTA factories decreased by 0.14 days, while those of polyester factories increased by 1.15 days. As of October 16, the average inventory usage days of domestic PTA manufacturers were 4.08 days, and the raw material inventory days of polyester factories were 7.35 days. It was estimated that the upward space of the polyester开工 rate was limited in the later period, and the inventory - reduction rhythm would slow down [59][65]. 3.3.3 Demand - **Polyester**: The average weekly price of PTA declined, and the overall demand was weak, which was negative for the polyester market. The average market prices of semi - bright POY150D/48F, DTY150D/48F, and FDY150D/96F decreased by 1.47%, 0.82%, and 1.13% respectively from the previous period. The average price of polyester staple fiber in the East China market was 6,326 yuan/ton, a decrease of 93 yuan/ton from the previous period, a change of - 1.45%. The negotiation range of polyester bottle chips in the East China region was 5,600 - 5,730 yuan/ton, and the average weekly price was 5,710.00 yuan/ton, a decrease of 2.14% from the previous period. The average weekly polyester production and sales were estimated to be 70%. The average weekly load of polyester factories was 89.38%, and the average weekly load of Jiangsu and Zhejiang looms was 68.22% [67][75]. - **Weaving**: The new export orders were placed slowly, and the weaving market lacked confidence in the future market. With the significant drop in temperature in the north, the online sales of autumn and winter textile and clothing accelerated, driving the sales of thick fabrics such as autumn and winter velvet and woolen fabrics. The starting rate of warp - knitting enterprises increased steadily. However, there was a risk of escalation of Sino - US trade frictions after the festival, and some export enterprises were accelerating the production of existing orders to avoid potential impacts [81][83].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - PTA: After the holiday, the negotiation atmosphere in the PTA spot market was average, and the spot basis weakened slightly. With some PTA device maintenance and production cuts, along with the delay of new device commissioning, the PTA supply - demand outlook improved. It is expected that the short - term spot price will still fluctuate mainly following the cost side. Attention should be paid to device changes and downstream production and sales [6]. - MEG: The price center of ethylene glycol adjusted at a low level on Monday, and the market negotiation was acceptable. The ethylene glycol market is expected to operate weakly in the short term, and attention should be paid to external factors and device changes. In October, the supply - demand pattern of ethylene glycol turned to inventory accumulation, with an overall inventory increase of around 50,000 tons, and there is continuous inventory accumulation pressure in the far - month, significantly pressuring market sentiment [8]. 3. Summary by Directory 3.1 Previous Day Review - PTA: Overnight crude oil tumbled last Friday but rebounded on Monday. PTA futures opened lower and fluctuated on the previous day, with a small decline in the end. The negotiation atmosphere in the spot market was average, and the spot basis weakened.

The spot price opened lower and then slightly recovered, and the spot basis weakened slightly in the afternoon. The overseas market center of ethylene glycol declined, and traders were the main participants in the trading [8]. 3.2 Daily Tips - PTA: The fundamentals were neutral; the basis was neutral; the inventory was bearish as the PTA factory inventory was 4.22 days, a 0.47 - day increase from the previous period; the disk was bearish as the 20 - day moving average was downward and the closing price was below it; the main position was bearish with a net short position and a reduction in short positions [7]. - MEG: The fundamentals were neutral; the basis was neutral; the inventory was bearish as the total inventory in East China was 445,100 tons, a 40,800 - ton increase from the previous period; the disk was bearish as the 20 - day moving average was downward and the closing price was below it; the main position was bearish with a net short position and a reduction in short positions [8]. 3.3 Today's Focus - Factors affecting PTA and MEG: - Bullish factors: Before the holiday, the polyester market had a booming sales under the combined positive effects of increased demand and rising oil prices. The inventory of POY and FDY in the pre - spinning of filament yarn quickly decreased to about half a month, and the price rebounded by 100 - 150 yuan. During the holiday, the polyester price remained stable. Some PTA device maintenance and production cuts, along with the delay of new device commissioning [9][10]. - Bearish factors: A 3.6 - million - ton PTA device in East China was gradually increasing its production to over 90%, after reducing production around October 7 [11]. 3.4 Fundamental Data - PTA Supply - Demand Balance Sheet: Provides PTA supply - demand data from January 2024 to December 2025, including production capacity, production, consumption, inventory, etc. [13]. - Ethylene Glycol Supply - Demand Balance Sheet: Provides ethylene glycol supply - demand data from January 2024 to December 2025, including production, import, consumption, port inventory, etc. [14]. - Price Data: Shows price changes of various products such as naphtha, PX, PTA, MEG, polyester filaments, and polyester staple fibers from October 10 to October 13, 2025, as well as basis and profit data [15].

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **Pure Benzene**: Recently, domestic supply - side disturbances have increased. With the maintenance of some refining and chemical plants in East and South China, production has decreased, and the import of Asian sources is restricted. Demand remains weak, and inventory in some areas has decreased. The cost has increased. In the short - term, the market may fluctuate strongly under the support of plant maintenance, but in the long - term, it is necessary to be vigilant against the suppression caused by OPEC+ production increase and less - than - expected demand recovery [2]. - **Styrene**: The supply has been continuously shrinking due to maintenance. Although production may increase this week, downstream device operation is differentiated, and inventory performance is also different. The cost of non - integrated enterprises has increased, and profit margins have been compressed. In September, the supply pressure is relatively alleviated. In the short - term, inventory is being reduced, but if demand does not improve significantly, the price increase space may be limited [3]. 3.

Report Industry Investment Rating No information provided Core Viewpoints of the Report - The report maintains the view of overweighting crude oil as geopolitical premiums have dissipated, OPEC's production increase is minimal, and the current oil price is relatively undervalued with good fundamentals. However, it's not advisable to chase the price at present, and if geopolitical premiums reappear, the oil price will have more upside potential [3]. - For methanol, the fundamentals are mixed with high inventory suppressing the price. It's recommended to wait and see as the price is greatly affected by overall commodity sentiment [6]. - Regarding urea, although the valuation is relatively low, there is a lack of driving factors in reality. It's suggested to wait and see or consider going long at low prices [9]. - For rubber, the medium - term view is bullish, but due to short - term technical breakdown, it's recommended to wait and see [14]. - For PVC, the domestic supply is strong while demand is weak, and exports are expected to decline. It's advisable to consider shorting on rallies in the medium term [17]. - For styrene, the long - term BZN is expected to recover, and it's recommended to go long on the pure benzene US - South Korea spread at low prices [20]. - For polyethylene, the price is expected to fluctuate upwards in the long term as the long - term contradiction shifts from cost - driven decline to South Korean ethylene clearance policy [23]. - For polypropylene, there is high inventory pressure in the context of weak supply and demand, and the high number of warehouse receipts suppresses the market [26]. - For PX, the current load is high, and there is a lack of driving factors with PXN under pressure. It's recommended to wait and see [30]. - For PTA, the supply has unexpected maintenance, and the demand is affected by the terminal. It's recommended to wait and see [33]. - For ethylene glycol, the industry is expected to accumulate inventory in the fourth quarter, and it's recommended to short on rallies with caution [35].

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Overall, the report analyzes multiple chemical products, with most showing a bearish or neutral outlook. The main influencing factors include supply - demand fundamentals, cost drivers, and geopolitical events. For crude oil, despite short - term geopolitical support, the medium - term supply surplus is likely, so a bearish view is maintained [1][2]. - For other products like styrene, rubber, and synthetic rubber, factors such as high inventory, weak demand, and cost pressure contribute to their bearish or neutral stances [5][8][11]. 3. Summary by Product Crude Oil - Logic: After a significant decline last week, a rebound on Friday night was related to geopolitical events. However, considering OPEC+ production increase and seasonal weakening of US demand, a supply surplus is likely in the second half of the year. The strategy is based on the bearish medium - term fundamentals [1][2]. - Technical Analysis: The daily - level shows a medium - term downward structure, and the hourly - level shows a short - term oscillating structure. The strategy is to hold short positions at the hourly level [2]. Styrene (EB) - Logic: The weekly fundamentals have not improved significantly. High profits, high production, and high inventory persist, and new device production in September - October will add to the supply pressure. The bearish view remains [5]. - Technical Analysis: The hourly - level shows a short - term oscillating structure. After a long - negative break today, the 15 - minute cycle is bearish with a pressure level at 7100. The strategy is to look for short - selling opportunities at the 15 - minute cycle [5]. Rubber - Logic: Overseas raw material prices have fallen, weakening cost support. Although inventory is decreasing, the year - on - year high pressure remains. The demand is neutral with no major contradictions [8]. - Technical Analysis: The daily - level shows a medium - term oscillating structure, and the hourly - level shows a downward structure. After a long - negative break today, the short - term downward trend is confirmed. The strategy is to hold short positions at the hourly level [8]. Synthetic Rubber (BR) - Logic: The supply - demand of synthetic rubber itself has no major contradictions. The main concern is the cost of butadiene, with increasing port inventory and future supply pressure. The bearish view is based on cost [11]. - Technical Analysis: The daily - level shows a medium - term oscillating/downward structure, and the hourly - level shows a short - term downward structure. After a new low today, the strategy is to hold short positions at the hourly level with a stop - profit at 11730 [14]. PX - Logic: PX profit has recovered, and the operating rate has increased. The demand recovery in the polyester peak season is slower than expected. The main driver is the cost of crude oil [16][18]. - Technical Analysis: The hourly - level shows a short - term oscillating structure. The 15 - minute cycle has turned bearish with a pressure level at 6760. The strategy is to look for short - selling opportunities at the 15 - minute cycle [18]. PTA - Logic: PTA supply has increased, and demand remains high but with weak terminal demand. The main driver is the cost of crude oil [19]. - Technical Analysis: The hourly - level shows a short - term oscillating structure. The strategy is to hold short positions at the hourly level [19]. PP - Logic: Demand has improved slightly in the peak season, but supply pressure has increased due to new device production. The strategy is to be cautious about short - selling after the price decline [22][23]. - Technical Analysis: The hourly - level shows a short - term oscillating structure. The 15 - minute cycle has turned bearish with a pressure level at 6975. The strategy is to look for short - selling opportunities at the 15 - minute cycle [23]. Methanol - Logic: High operating rate and high imports have led to inventory pressure. Although downstream MTO profit has improved, the bearish view remains [26]. - Technical Analysis: The daily - level shows a medium - term downward/oscillating structure, and the hourly - level shows a short - term downward structure. After a new low today, the strategy is to hold the remaining short positions at the hourly level with a stop - profit at 2435 [26]. PVC - Logic: High production and high inventory persist due to high - profit烧碱 and weak domestic demand. The fundamentals are under pressure [29]. - Technical Analysis: The daily - level shows a medium - term upward structure, and the hourly - level shows a short - term upward structure. After a long - negative break today, the strategy is to wait and see at the hourly level [29]. Ethylene Glycol (EG) - Logic: The operating rate of MEG and downstream has little change, and inventory is slightly decreasing. However, future supply pressure from new devices should be noted [30]. - Technical Analysis: The daily - level shows a medium - term oscillating/downward structure, and the hourly - level shows a short - term downward structure. After a decline today, the strategy is to hold short positions at the hourly level with a stop - profit at 4335 [30]. Plastic - Logic: PE operating rate has declined, but new capacity has been put into production. Demand has improved slightly in the peak season but is still below expectations. Further decline depends on the weakening of crude oil [33]. - Technical Analysis: The daily - level shows a medium - term oscillating/downward structure, and the hourly - level shows a short - term downward structure. After a decline today, the strategy is to hold short positions at the hourly level with a stop - loss at 7270 [33]. Soda Ash - Logic: Supply has increased slightly, and the high - production and high - inventory situation remains. After a price decline, short - selling should be cautious, and there is no upward driver in the short term [37]. - Technical Analysis: The hourly - level shows an upward structure. After a long - negative break today, the 15 - minute cycle has turned bearish with a pressure level at 1320. The strategy is to look for short - selling opportunities at the 15 - minute cycle [37]. Caustic Soda - Logic: Supply of liquid chlorine is sufficient, and demand from alumina and other industries has recovered. Inventory has decreased, and the short - term fundamentals have improved. The medium - term focus is on device maintenance and demand improvement [40]. - Technical Analysis: The hourly - level shows a downward structure. After a long - negative break today, the strategy is to hold short positions at the hourly level with a stop - profit at 2625 [40].
