1. Report Industry Investment Rating No relevant information provided. 2. Core Views Polyolefin Industry - The current core contradiction in the polyolefin market is not prominent. In the PE market, the current maintenance remains high, and the short - term supply pressure is relatively limited. In the PP market, propane is strong, PDH losses intensify, and short - term unplanned maintenance increases. However, after the new device is put into production in early September, the pressure in East China increases, driving the basis to weaken rapidly, and market transactions are dull [23]. Pure Benzene and Styrene Industry - The supply of pure benzene in September is expected to be more relaxed than expected due to the maintenance of a reforming device in East China, and the weakening demand support will limit the price drive. For styrene, the overall start - up of downstream 3S has rebounded this week, and the port inventory has fallen from a high level. There is an expectation of improvement in supply and demand in the future, but the rebound space is limited due to high port inventory [26]. Chlor - Alkali Industry - The caustic soda market has stabilized slightly in the past two days, and the supply is expected to decline next week. The demand is expected to weaken in the future, but the inventory pressure of caustic soda enterprises is not large, and the spot price may remain firm in the short term. The PVC market has stopped falling and stabilized recently, but the overall pattern of oversupply is difficult to reverse, and there is no obvious sign of improvement in demand [30]. Polyester Industry - PX supply is gradually increasing to a relatively high level, and the supply - demand expectation in September is relatively loose, but the medium - term supply - demand is still expected to be tight. PTA supply - demand is expected to be tight in September, but the basis and processing fees have limited repair drivers. Ethylene glycol supply is strong in the short term and weak in the long term. Short - fiber supply - demand is still weak in the short term. Bottle - chip supply - demand may be balanced in September, and inventory may increase slightly [33]. Crude Oil Industry - Overnight oil prices fell due to concerns about supply surplus overwhelming the premium brought by geopolitical risks. In the short term, oil prices are likely to run weakly, and it is recommended to take a short - side approach [38]. Urea Industry - The urea futures price is running weakly due to the dual pressure of increased supply and weak demand. The domestic urea daily output has rebounded, while agricultural demand is in the off - season, and industrial demand is limited [42]. Methanol Industry - The methanol supply is expected to increase in September as domestic maintenance devices return and foreign start - up reaches a seasonal high. The demand from traditional downstream industries remains weak, and the port inventory has increased significantly, with weak basis performance and prominent pressure [44]. 3.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Chlor - Alkali Industry - The caustic soda futures price may have limited downside space. The spot price may remain firm in the short - term due to low inventory pressure on caustic soda enterprises and expected supply decline. Attention should be paid to the alumina plant's purchasing rhythm and device fluctuations [2]. - The PVC futures price will continue to be weakly volatile. The supply - demand pressure increases, and the demand has not improved. Although in the traditional peak season, the demand remains sluggish. The cost side provides some support [2]. Methanol Industry - On the supply side, inland maintenance devices are expected to gradually resume in early September, and the import volume will still be large. On the demand side, traditional downstream sectors are still weak. The port has been significantly accumulating inventory, and the basis is weak. The key is to focus on the inventory digestion rhythm [5]. Urea Industry - The urea futures price is running weakly due to the short - term imbalance of domestic supply - demand fundamentals. The supply is abundant, while the demand is weak, leading to inventory accumulation in factories [11]. Crude Oil Industry - The overnight oil price continued to fluctuate widely. The current oil price is supported by geopolitical premiums, but the upside space is restricted by the loose fundamentals. It is recommended to mainly observe on the long - short side and wait for opportunities to expand the spread on the options side [44]. Polyester Industry Chain - PX: The supply is gradually increasing to a relatively high level, and the mid - term supply - demand is expected to be tight. The price has support at the low level, but the upside space of the rebound is limited. It is recommended to treat PX11 as a short - term shock between 6600 - 6900 [39]. - PTA: The supply - demand in September is expected to be tight, but the basis and processing fee repair drive are limited. It is recommended to treat TA as a short - term shock between 4600 - 4800 and mainly conduct TA1 - 5 rolling reverse spreads [39]. - Ethylene glycol: The supply - demand pattern is strong in the near - term and weak in the long - term. It is expected to slightly reduce inventory in September and enter the inventory accumulation channel in the fourth quarter. Attention should be paid to the support of EG01 at around 4300 and the EG1 - 5 reverse spread opportunity [39]. - Short - fiber: The short - term supply - demand pattern is still weak, following the raw material fluctuations. The unilateral strategy is the same as that of PTA, and the processing fee on the disk fluctuates between 800 - 1000 [39]. - Bottle chips: In September, the supply and demand may both decrease, and the inventory is expected to increase. PR follows the cost fluctuations, and the processing fee has limited upside space [39]. Polyolefin Industry - For PP, the loss of PDH is intensifying, and the basis has weakened rapidly. For PE, the current maintenance is still at a relatively high level, and the supply pressure is relatively limited in the short - term. The overall market will present a pattern of "decreasing supply and increasing demand" [49][51]. Pure Benzene - Styrene Industry - Pure benzene: The supply in September is lower than expected, and the demand support is weakening. The supply - demand is expected to be loose, and the price is driven by the strong oil price. BZ2603 is expected to follow styrene and fluctuate strongly [57]. - Styrene: The short - term drive is weak, but the supply - demand is expected to improve in the future. The price is supported by the oil price, but the rebound space is limited by high inventory. EB10 can be treated with low - buying on a rolling basis, and attention should be paid to the pressure around 7200 and the spread expansion between EB11 - BZ11 [57]. 3.

Group 1 - The domestic liquid caustic soda market is stable with acceptable transaction volumes, particularly in Shandong where demand remains decent and transportation in Tianjin has resumed, alleviating some shipping pressures for chlor-alkali enterprises [1] - The main prices for 32% liquid caustic soda in Shandong are between 850-915 RMB/ton, while the 50% liquid caustic soda prices range from 1340-1360 RMB/ton [1] Group 2 - As of Thursday, the national average operating rate for major sample enterprises is 86.09%, down 1.25 percentage points from last week due to increased maintenance of chlor-alkali facilities [2] - The inventory of 32% liquid caustic soda in East China decreased by 18.81% to 189,650 tons as of August 20, while Shandong's inventory fell by 19.31% to 67,700 tons, indicating improved purchasing activity from downstream sectors [2] Group 3 - Following the recent military parade, transportation disruptions are expected to ease, allowing liquid caustic soda companies to resume normal supply to downstream markets, with short-term market support from demand [3] - The current low inventory levels in Shandong and the recovery in non-aluminum downstream demand are likely to keep spot prices firm, with increased purchasing activity anticipated as traders prepare for upcoming demand [3]

Report Industry Investment Rating - Not provided in the content Core Viewpoint - The report holds a view of strong current situation but weak future expectations, predicting that the off - season contracts of caustic soda are likely to operate weakly [4] Summary by Relevant Catalogs Supply Side - As of August 29, the weekly production of caustic soda reached 813,200 tons, still at a relatively high level in the past five years but showing a decline. The average operating rate dropped from a peak of 85.1% to 82.4%. The main reasons are the arrival of the autumn regular maintenance peak and temporary shutdowns of some enterprises in Shandong due to traffic control. The current maintenance capacity is 3.13 million tons, and according to the maintenance plan, 2.79 million tons and 1.31 million tons of new maintenance devices are expected in September and October respectively, with the operating rate unlikely to return to the previous high in September. However, some chlor - alkali plants have resumed production after the traffic control in Shandong was lifted [6] - The planned new production capacity this year has decreased from over 4 million tons at the beginning of the year to 2.25 million tons, with some projects postponed to next year due to environmental approval and production profit issues. Currently, Shandong Hydrogen Energy New Energy, Shandong Qingdao Bay, Tianjin Bohua Chemical, and Gansu Yaowang Chemical have all been put into production, and there are still 1.15 million tons of production capacity to be put into operation in the fourth quarter. The achievement rate of production capacity needs to be continuously tracked. Additionally, about 19.25 million tons of caustic soda production capacity is over 20 years old, accounting for 39% of the total capacity. Since the industry is still profitable overall, the impact of the "anti - involution" policy is expected to be limited, and policy changes need to be continuously observed [6] Demand Side - In terms of alumina demand, as of August 29, the latest weekly output of alumina reached 1.847 million tons, at a high level this year. Alumina plants are still profitable, and with the increase in new production in the fourth quarter, the output is expected to rise steadily. Although the alkali - preparation demand before production is lower than that in the first half of the year, the incremental daily alkali consumption demand will still strongly support the caustic soda consumption this year [14] - In terms of non - aluminum demand, the cumulative output of viscose staple fiber in the first seven months of this year was 2.89 million tons, a slight increase of 1.7% compared with the same period last year. The recent seasonal peak season has driven an increase in alkali - preparation demand. The overall starting rate of the printing and dyeing industry is lower than last year, but it has also entered the seasonal peak season recently, with the starting rate rising compared to the previous period. The elasticity and sustainability of peak - season demand need to be continuously observed [14] Market Outlook - The demand side of caustic soda is currently in the early stage of the seasonal peak season. The production has declined due to autumn maintenance, and the inventory has decreased temporarily. The spot price is expected to remain strong in the short term. However, as the peak - season demand fades and the autumn - maintenance production capacity returns, coupled with the fact that the caustic soda inventory this year is still at a high level in recent years, the supply of caustic soda is expected to return to an oversupply situation after October. Therefore, if the seasonal peak season and the overall optimistic sentiment in the commodity market drive the off - season 01 contract to rise significantly to an overvalued level, short positions can be established at high prices after the market fluctuations stabilize or after the warehouse receipts start to be registered. The reference operating range for SH2601 is 2,200 - 2,800 yuan per ton. The changes in peak - season inventory, the registration volume of warehouse receipts, and the progress of alumina production capacity commissioning need to be continuously tracked [3][19]
