Report Summary 1. Investment Ratings The report does not provide any industry investment ratings. 2. Core Views - **Chlor - Alkali Industry**: The caustic soda market has a high supply, and there is a possibility of price cuts. PVC is expected to stop falling and stabilize in the peak season from September to October, but the supply - demand contradiction is still difficult to ease [2]. - **Crude Oil Industry**: The current oil market shows a game between weak macro - expectations and tight spot fundamentals. It is likely to operate in a short - term range. It is recommended to focus on unilateral segment operations [24]. - **Methanol Industry**: The port inventory has decreased. The supply in the inland is at a relatively high level, and the demand is weak. The overall valuation is neutral, and the futures price fluctuates between high inventory and overseas gas - restriction expectations [29]. - **Urea Industry**: The urea futures market shows a weak and volatile pattern, mainly due to the deepening contradiction between high supply and weak demand. Although the cost provides some support, it is difficult to reverse the market downturn [37]. - **Polyolefin Industry**: PP production has decreased recently, and the inventory has declined. PE maintenance has reached a high point, and the upstream and mid - stream inventory has decreased. The pressure of inventory accumulation for 01 contracts is relatively large, which limits the upward space [43]. - **Polyester Industry**: PX supply increases, and the fourth - quarter supply - demand is expected to be weak. PTA supply is expected to shrink, and the short - term basis is supported. Ethylene glycol supply - demand is gradually weakening. Short - fiber support is strong in the short - term, and bottle - chip supply - demand is still loose [46]. - **Styrene Industry**: The supply of pure benzene is loose, and the demand support is limited.

1. Report Industry Investment Rating There is no information about the industry investment rating in the provided reports. 2. Core Views of the Report - The oil price is expected to fluctuate strongly in the short - term due to inventory depletion, geopolitical factors, and market sentiment. The Brent crude oil has strong support at the $65 level [1]. - The prices of high - and low - sulfur fuel oil may rebound slightly following the oil price, but the upside space is limited due to increasing supply in the future [2]. - The asphalt price is expected to remain stable in the short - term, and attention should be paid to the actual realization of the demand peak season [2]. - The prices of polyester products such as TA and ethylene glycol are expected to fluctuate weakly due to factors like increased maintenance in the fourth quarter, slow recovery of terminal demand, and pressure on long - term oil prices [4]. - The rubber price is expected to fluctuate mainly due to the slow recovery of production, stable downstream tire demand, and weakening export support [6]. - The methanol price is expected to enter a phased bottom, and the basis will gradually strengthen, but there are risks in short - term unilateral long positions [6]. - The polyolefin market will show a weakly fluctuating pattern with marginal improvement in demand and little change in supply [8]. - The PVC price is expected to fluctuate weakly due to high - level supply, slow recovery of domestic demand, and weakening exports [8][9]. 3.

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Crude Oil - Overnight oil prices rose due to increased market concerns about supply tightening, especially the return of geopolitical risk premiums. The attacks on Russian refining and export facilities by Ukraine led to concerns about supply disruptions, verified by the strengthening of diesel crack spreads and traders' bets on price increases. Additionally, the unexpected decline in US crude inventories and lower gasoline and distillate inventories supported the demand side. The short - term support for oil prices has increased, but marginal supply increments will limit the rebound amplitude. It is recommended to conduct unilateral band operations, with WTI in the range of [60, 66], Brent in [64, 69], and SC in [471, 502]. For options, wait for opportunities to expand after volatility increases [2]. Polyester Industry Chain - **PX**: Supply is expected to be abundant due to negative short - term operations and postponed maintenance of some domestic PX plants. Demand is weak as PTA processing fees are low, new PTA plants' commissioning is delayed, and multiple PTA plants have maintenance plans. PXN is expected to compress, but short - term prices may be supported by geopolitical events and pre - holiday demand. Strategies include short - term long on PX11 or shorting after a rebound [7]. - **PTA**: Supply is expected to shrink as new plant commissioning is delayed and maintenance plans are in place. Pre - holiday restocking demand supports the short - term basis, but the rebound space is limited under weak expectations. Absolute prices may be supported by geopolitical factors. Strategies include short - term long on TA or shorting after a rebound, and rolling reverse arbitrage on TA1 - 5 [7]. - **Ethylene Glycol**: Short - term imports are expected to be low, and inventory is expected to decline. However, the terminal market is weak, and the basis fluctuates at a high level. In the long - term, supply will increase as new plants start up and demand seasonally declines, leading to inventory accumulation. Strategies include selling call options EG2601 - C - 4400 at high prices and reverse arbitrage on EG1 - 5 [7]. - **Short Fiber**: Supply is at a high level, and demand is in the peak season but with limited new orders. Prices are supported at low levels but lack upward momentum, following raw material fluctuations. Strategies are the same as PTA, and the processing fee on the disk oscillates between 800 - 1100 [7]. - **Bottle Chips**: Supply in September is lower than expected due to typhoons, and low prices and pre - holiday restocking demand support prices and processing fees. However, the supply - demand pattern remains loose. Strategies are the same as PTA, and the main - contract processing fee on the disk is expected to oscillate between 350 - 500 yuan/ton [7]. Urea - Urea futures rebounded on September 24 due to expectations of short - term supply contraction and technical repair. Shanxi Tianze plans to shut down some large - scale plants on October 7, which supports market sentiment. Although spot demand is weak, export orders provide some support [14][16]. Methanol - This week, both port and inland inventories decreased, partly due to typhoons in South China. Supply in the inland area is at a high level, and although unplanned maintenance has increased, some plants are expected to resume production in mid - September. The inventory pattern in the inland area is healthy, supporting prices. Demand is weak due to the traditional off - season. The overall valuation is neutral. The disk fluctuates between trading the reality of high inventory and weak basis and the expectation of overseas gas restrictions in the long - term [19]. Pure Benzene and Styrene - **Pure Benzene**: Supply is expected to remain high as some plants resume production or start producing, and there are maintenance plans. Demand is weak as most downstream products are in the red, and there are many maintenance plans for downstream plants in September - October. However, continuous de - stocking at ports may provide some support. Prices are driven by geopolitical and macro factors in the short - term. Strategies include BZ2603 following styrene and crude oil fluctuations [23]. - **Styrene**: Downstream demand is fair due to peak - season demand and pre - holiday stocking, but it is mainly for rigid needs. Supply is expected to decrease as overseas plants are under maintenance and exports are expected to increase. Port inventories are accumulating, pressuring prices. Strategies include shorting EB11 on price rebounds and widening the spread of EB11 - BZ11 [23]. Chlor - Alkali Industry - **Caustic Soda**: The market is weak. Supply is high, and the decline in alumina prices has squeezed the profit margins of domestic alumina enterprises, weakening the support for spot prices. Inventory in North China is rising, while in East China, it is falling due to tight supply and non - aluminum rigid demand. In Shandong, prices may continue to decline before the National Day holiday. Short - selling positions can be held [27]. - **PVC**: The market is also weak, and the supply - demand contradiction is difficult to resolve. Supply is expected to increase as many plants finish maintenance next week. Demand is limited as downstream product start - up rates are low, and buyers are resistant to high prices. Cost support is provided by rising calcium carbide prices and stable ethylene prices. PVC is expected to stop falling and stabilize during the September - October peak season [27]. Polyolefins - **PP**: Production has decreased recently due to heavy losses in PDH and external - propylene procurement routes, leading to increased unplanned maintenance and lower inventory. - **PE**: Maintenance has reached a peak, and the start - up rate is gradually increasing. Inventory in the upstream and mid - stream has decreased this week. More import offers from North America are emerging, and the supply rhythm and import offers need to be monitored. There is pressure on inventory accumulation for the 01 contract [31]. 3.

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefin - LLDPE and PP: Recently, PP production has declined due to significant losses in PDH and externally - sourced propylene routes, leading to increased unplanned maintenance and decreased inventory. PE maintenance has reached a peak, and the start - up rate is gradually rising. This week, the inventory of the upper and middle reaches has decreased, and there are more import offers from North America. Currently, there is a large inventory accumulation pressure on the 01 contract, which limits the upside space [2]. Methanol - The market is trading high inventory and fast loading in Iran. Coastal inventory has reached a record high, market sentiment has deteriorated, prices have weakened, and the basis has slightly weakened. In terms of supply and demand, inland supply is at a high level year - on - year. Although unplanned maintenance has increased recently, some devices are expected to resume production in mid - September. The inland inventory pattern is relatively healthy, which supports prices. On the demand side, affected by the off - season of traditional downstream industries, demand is weak. Port arrivals are still high, inventory accumulation is significant, and trading has weakened. In terms of valuation, upstream profits are neutral, MTO profits are strengthening, and traditional downstream profits are slightly strengthening, with the overall valuation being neutral. The port is continuously accumulating inventory significantly, and the import volume in September remains high. The futures price fluctuates between trading the current high inventory and weak basis and the expected overseas gas restriction in the distant future. Attention should be paid to the inventory inflection point [5]. Pure Benzene and Styrene - Pure Benzene: Recently, some pure benzene devices have restarted or produced products, and some maintenance plans have been postponed, so the supply is expected to remain at a relatively high level. On the demand side, most downstream products of pure benzene are still in a loss state, and some second - tier downstream products have high inventory. In September and October, both planned and unplanned production cuts in downstream styrene devices have reduced the demand support. The supply - demand expectation for pure benzene in September is still relatively loose, and the price driving force is weak. In the short term, the price is affected by geopolitical and macro - factors. - Styrene: Driven by the peak - season demand and pre - National - Day stocking of some factories, the overall demand for styrene downstream is okay, but the increase is limited. On the supply side, under the pressure of inventory and industry profits, more devices have shut down or reduced production. Some devices have reduced production due to accidents, and the export expectation of styrene has increased due to overseas device maintenance, so the supply is expected to decrease. Port inventory has accumulated, which may put pressure on the styrene price. In the short term, styrene may be affected by the oil price, geopolitical situation, and the alleviation of concerns about marginal supply increase [10]. Crude Oil - Overnight oil prices rose. The main trading logic is that the market's concerns about the current supply surplus have eased, and the geopolitical risk premium has resurfaced. Specifically, the oil export agreement of the Iraqi Kurds has reached a deadlock, eliminating about 230,000 barrels per day of new supply, which is the key trigger for the rebound after the previous continuous decline in oil prices and also provides support for the near - month spread. At the same time, Ukraine's attack on Russian refineries and the tough stance of NATO have magnified the supply interruption risk of refined oil products, pushed up the cracking spread, and affected the oil price from the sentiment and cost aspects. Overall, although the IEA report and other macro - factors still point to a supply surplus, in the short term, geopolitical factors have become the main pricing factor in the market, temporarily overriding the bearish expectation of potential inventory increase. In the short term, oil prices are expected to move within a range. It is recommended to mainly conduct high - selling and low - buying operations, with the operating range of WTI at [60, 66], Brent at [64, 69], and SC at [471, 502]. For options, wait for opportunities to widen the spread after the volatility increases [21][22]. Urea - The urea futures price has been weakly oscillating recently. The main logic is sufficient supply and insufficient demand support. Specifically, the daily industry output remains at a high level of over 200,000 tons, and new production capacity is about to be released, increasing the supply pressure. At the same time, agricultural demand has entered the off - season, and industrial demand has weakened due to the decline in the compound fertilizer start - up rate. Although there are some export port - collection orders, the overall impact is limited. The lack of market confidence and continuous inventory accumulation further suppress the futures price, and there is a lack of substantial positive driving factors [25]. PX, PTA, Ethylene Glycol, Short - fiber, and Bottle - chip - PX: Recently, the short - process capacity utilization at home and abroad has increased, and the maintenance of some domestic PX devices has been postponed. In addition, multiple PTA devices have maintenance plans. The supply - demand expectation for PX in the fourth quarter is further weakened. However, it may be supported by oil prices in the short term. - PTA: Due to the continuously low processing fees of PTA, the commissioning of new PTA devices has been postponed, and multiple PTA devices have maintenance plans. The spot basis has been continuously weak. In terms of absolute price, it is affected by the situation in Ukraine's attack on Russian oil facilities. - Ethylene Glycol: The supply - demand situation is gradually weakening. In the short term, the import expectation in September is not high, and the basis is oscillating at a high level. In the long term, the supply - demand expectation for ethylene glycol in the fourth quarter is weak, mainly due to the start - up of new devices and the seasonal decline in demand in the fourth quarter, and ethylene glycol will enter an inventory accumulation cycle. - Short - fiber: The short - term supply - demand pattern is weak. Recently, the short - fiber supply has remained at a high level. On the demand side, although it is the peak season, new orders are limited, and the peak season this year is not very prosperous. The short - fiber price has support at the low level, and the processing fee oscillates between 800 - 1100, with limited upward and downward driving forces. - Bottle - chip: Recently, some bottle - chip devices have restarted while some have shut down, and the overall production reduction intensity remains basically unchanged. With the downstream's low - price replenishment demand, the absolute price and processing fee of bottle - chip are supported, and the inventory has decreased. However, the upward space is limited, and attention should be paid to whether the production reduction of bottle - chip devices will further increase and the downstream follow - up situation [28]. Chlor - alkali (Caustic Soda and PVC) - Caustic Soda: The futures price continued to weaken yesterday. This week, the supply has increased, and the start - up rate of sample enterprises has increased. On the downstream side, the continuous decline in domestic and overseas alumina prices has continuously narrowed the profit margin of domestic alumina enterprises, and the support for the spot price is weak. Affected by the decline in the purchase price of the main downstream in Shandong and the cautious downstream purchasing, the inventory in the North China region has increased. In the East China region, the enterprises under maintenance and load - reduction have not resumed, the supply is tight, and the non - aluminum demand has followed up as a rigid demand, so the inventory has decreased. This week, in the Shandong market, due to the approaching National Day holiday, the short - term local caustic soda inventory needs time to be released. With the current high supply and the poor unloading of the main downstream, there is a possibility of further price cuts. It was previously recommended to take short positions, and the short positions can be held. - PVC: The futures price weakened yesterday, and the fundamental supply - demand contradiction is still difficult to resolve. On the supply side, many enterprises will end their maintenance next week, and the production is expected to increase. On the demand side, the start - up rate of downstream products has increased limitedly, and some have completed their inventory replenishment, so they are resistant to high prices and have average purchasing enthusiasm. On the cost side, the price of raw material calcium carbide continues to rise, and the ethylene price remains stable, providing bottom - line support for costs. It is expected that PVC will stop falling and stabilize during the peak season from September to October. Attention should be paid to the downstream demand performance [36].

Report Industry Investment Ratings - No information provided regarding industry investment ratings. Core Views Polyolefin Industry - LLDPE and PP: Recent PP production decline due to losses in PDH and external propylene routes, leading to unplanned maintenance and inventory reduction. PE maintenance has reached a peak, with increasing开工 and de - stocking of mid - upstream inventory this week. More import offers from North America are emerging, and future supply rhythm and import offers need attention. Currently, the 01 contract faces significant inventory accumulation pressure, limiting upward space [2]. Methanol Industry - The market is trading high inventory and fast Iranian shipments. Coastal inventory has reached a record high, weakening market sentiment and prices, with a slight weakening of the basis. On the supply - demand side, inland supply is at a high level year - on - year. Although unplanned maintenance has increased recently, some plants are expected to resume production in mid - September. The inland inventory pattern is relatively healthy, providing some support for prices. Demand is weak due to the traditional off - season of downstream industries. Port arrivals are still high, with large inventory accumulation and weakening transactions. Overall valuation is neutral. The market is oscillating between high - inventory reality, weak basis, and overseas gas - restriction expectations in the future. Attention should be paid to the inventory inflection point [4]. Styrene Industry - Pure benzene: Recently, some plants have restarted or produced products, and maintenance plans have been postponed, keeping supply at a relatively high level. On the demand side, most downstream products are in a loss state, and the secondary - downstream inventory of some products is high. There are planned and unplanned production cuts in styrene plants from September to October, weakening demand support. The supply - demand outlook for pure benzene in September remains loose, with weak price drivers. In the short term, price trends are affected by geopolitical and macro factors. - Styrene: Driven by peak - season demand and pre - National - Day stocking of some factories, overall demand is okay but with limited growth. On the supply side, due to inventory and profit pressure, more plants have stopped or reduced production, and some have cut production due to accidents. With overseas plant maintenance, styrene export expectations have increased, reducing supply expectations. Port inventory has accumulated, pressuring styrene prices. In the short term, styrene may be affected by oil - price geopolitical situations and reduced concerns about supply increments. Strategies include short - selling on price rebounds for EB11 and widening the EB11 - BZ11 spread at low levels, but the driving force is limited [13]. Crude Oil Industry - Overnight oil prices rose. The main trading logic is that market concerns about immediate supply surplus have eased, and geopolitical risk premiums have resurfaced. Specifically, the deadlock in the oil - export agreement in the Kurdistan region of Iraq has dispelled the expectation of about 230,000 barrels per day of new supply, triggering a key rebound after the previous oil - price decline and supporting the near - month spread. Meanwhile, Ukraine's attack on Russian refineries and NATO's tough stance have increased the risk of supply disruption of Russian refined products such as diesel, pushing up the crack spread and supporting crude oil from both sentiment and cost aspects. Overall, although macro - level reports such as those from the International Energy Agency still point to a loose supply situation, short - term geopolitical factors have become the main pricing factor in the market, temporarily overriding the bearish expectation of potential increases in US crude - oil inventory. In the short term, oil prices are expected to trade in a range. It is recommended to conduct band - trading on a single - side basis, with the WTI trading range at [60, 66], Brent at [64, 69], and SC at [471, 502]. For options, wait for opportunities to widen the spread after volatility increases [32]. Urea Industry - Urea futures prices have been weakly oscillating recently. The main logic is sufficient supply and insufficient demand support. Specifically, the daily industry output remains above 200,000 tons, and new production capacity is about to be released, increasing supply pressure. Agricultural demand has entered the off - season, and industrial demand has weakened due to the decline in compound - fertilizer plant开工. Although there are some export - port - collection orders, the overall impact is limited. Market confidence is lacking, and continuous inventory accumulation further suppresses the futures price, lacking substantial positive drivers [37]. Polyester Industry - PX: Recent increases in PX supply are obvious due to the capacity increase from short - process production at home and abroad and the postponement of maintenance of some domestic PX plants. On the demand side, due to low PTA processing fees, new PTA plant commissioning has been delayed, and multiple PTA plants have maintenance plans. The supply - demand outlook for PX in the fourth quarter is expected to weaken further, with an expected compression of the PXN spread. In terms of absolute price, the attack on Russian oil - distribution facilities by Ukraine has boosted short - term oil prices, which may support PX in the short term. Strategies include short - term long - positions on PX11 or short - selling on price rebounds. - PTA: Due to low processing fees, new PTA plant commissioning has been delayed, and multiple PTA plants have maintenance plans, reducing supply expectations. However, the peak - season performance of downstream industries is average, and the spot basis of PTA has been weakly running. In terms of absolute price, short - term oil - price increases may support PTA. Strategies include short - term long - positions or short - selling on price rebounds for TA, and a rolling reverse - spread strategy for TA1 - 5. - Ethylene glycol: Supply - demand is gradually weakening. In the short term, ethylene - glycol imports in September are expected to be low, and inventory is expected to decrease this month, keeping port inventory at a low level. However, the terminal market is currently weak, and the basis is oscillating at a high level. In the long term, the supply - demand outlook for ethylene glycol in the fourth quarter is weak, as the Yulong Petrochemical plant has increased its load to 60% - 70%, the Satellite Petrochemical plant will restart in October, and demand will decline seasonally in the fourth quarter. Ethylene glycol will enter an inventory - accumulation phase, facing upward pressure. Attention should be paid to the progress of plant commissioning and restart. Strategies include selling call options EG2601 - C - 4400 on price increases and a reverse - spread strategy for EG1 - 5. - Short - fiber: The short - term supply - demand pattern is weak. Recently, short - fiber supply has remained high. On the demand side, although it is the peak - season of "Golden September and Silver October" and downstream industries have restocking demand before the National Day, new orders for gray fabrics are limited, and this year's peak - season performance is average. Short - fiber prices are supported at low levels, but the upward - rebound driving force is weak, and the price movement follows raw - material fluctuations. Strategies are the same as for PTA on a single - side basis. The processing fee on the futures market is expected to oscillate between 800 - 1100 yuan/ton, with limited upward and downward driving forces. - Bottle - grade polyester chips: Recently, some bottle - grade polyester chip plants have restarted while others have stopped production, with overall production capacity remaining basically unchanged. As the price has dropped to the lowest level of the year and there is rigid restocking demand before the National Day, downstream industries and traders are replenishing inventory at low prices, supporting the absolute price and processing fee of bottle - grade polyester chips and reducing inventory. However, the supply - demand situation remains loose. PR prices follow the cost - end fluctuations, and the upward space of the processing fee is limited. Attention should be paid to whether there will be more production cuts in bottle - grade polyester chip plants and the downstream follow - up situation. Strategies are the same as for PTA on a single - side basis. The processing fee of the PR main - contract on the futures market is expected to oscillate between 350 - 500 yuan/ton [40][41]. Chlor - alkali Industry - Caustic soda: The futures price continued to weaken yesterday. Supply has increased this week, and the开工 rate of sample enterprises has increased. On the downstream side, recent continuous declines in domestic and overseas alumina prices have narrowed the profit margin of domestic alumina enterprises, weakening the support for spot prices. Affected by the decline in the purchase price of the main downstream in Shandong and cautious downstream purchasing, inventory in the North China region has increased. In the East China region, enterprises with maintenance and load - reduction devices have not yet resumed, resulting in tight supply. Non - aluminum demand has followed up as a rigid need, and inventory has decreased. This week, in the Shandong market, due to the approaching National Day holiday, it will take time to release short - term local caustic - soda inventory. With the current high - level supply and poor sales in the main downstream, there is a possibility of further price cuts. Previously, short - selling was recommended, and short positions can be held. - PVC: The futures price weakened yesterday, and the supply - demand contradiction in the fundamentals is still difficult to resolve. On the supply side, many plants will end maintenance next week, with expected production increases. On the demand side, the开工 rate of downstream products has increased limitedly, and some have completed inventory replenishment, being resistant to high prices and having average purchasing enthusiasm. On the cost side, the price of raw - material calcium carbide has been rising, and the ethylene price has remained stable, providing bottom - level support for costs. It is expected that PVC will stop falling and stabilize during the peak season from September to October. Attention should be paid to the downstream demand performance [45].

Report Industry Investment Ratings - Acrylonitrile: ★★★ (Three stars represent a clearer long/short trend, and there is still a relatively appropriate investment opportunity currently) [1] - Plastic: ★★★ [1] - Pure Benzene: ★★★ [1] - Styrene: ★★★ [1] - PX: ★★★ [1] - PTA: ★★★ [1] - Ethylene Glycol: ★★★ [1] - Short Fiber: ★★★ [1] - Bottle Chip: ★★☆ [1] - Methanol: ★★★ [1] - Urea: ★★★ [1] - PVC: ★★★ [1] - Caustic Soda: ★★★ [1] - Soda Ash: ★☆☆ (One star represents a bullish/bearish bias, indicating a driving force for price increase/decrease, but the market is not very operable) [1] - Glass: ★★★ [1] Core Viewpoints - The futures of olefins and polyolefins continued to decline. The supply pressure from the restart of northern acrylonitrile plants is emerging, and the market sentiment is bearish. The demand for raw material replenishment by terminal enterprises and the release of upstream production capacity are in a multi - short game, showing a weakening trend. The supply of polyolefins is expected to increase, while the demand support is limited [2]. - The price of pure benzene continued to fall, with a slight narrowing of the decline in East China. The actual fundamentals are okay, but the high expected import volume and poor profits of downstream products drag down the market. The supply, demand, and inventory of styrene are expected to increase, but the supply increase is greater than the demand increase, so the price trend is weak [3]. - The supply - demand strong expectation of PX is weakened, and the valuation is under pressure. The processing margin and basis of PTA have been repaired, but the industry profit is still poor. The price of ethylene glycol has been falling, with weak expectations. The short - fiber price has followed the raw materials and the external sentiment to decline, and the near - month contract can be allocated bullishly. The bottle - chip industry has over - capacity, and the expected processing margin repair space is limited [4]. - The methanol futures hit a new low. The high port inventory and the expectation of continuous inventory accumulation suppress the price increase. The urea market is in a situation of oversupply and may continue to be under pressure [5]. - The PVC price followed the macro sentiment to decline, with a loose supply - demand pattern and high inventory pressure. The caustic soda price dropped sharply, with a weak current situation and a strong future expectation [6]. - The soda ash industry is in a situation of oversupply, and the price is falling. The glass market has a pattern of high supply and weak demand, with a high - level decline in price [7]. Summaries by Categories Olefins - Polyolefins - Acrylonitrile futures continued to decline. The supply pressure from the restart of northern plants is emerging, and the market sentiment is bearish. There is a multi - short game between terminal demand and upstream production capacity release, showing a weakening trend [2]. - Polyolefin futures continued to decline. The supply of polyethylene is expected to increase, and the demand support is limited. The supply of polypropylene is also expected to increase, while the demand is weak [2]. Pure Benzene - Styrene - The price of pure benzene continued to fall, with a slight narrowing of the decline in East China. The actual fundamentals are okay, but the high expected import volume and poor profits of downstream products drag down the market [3]. - Styrene futures declined. The supply, demand, and inventory are expected to increase, but the supply increase is greater than the demand increase, so the price trend is weak [3]. Polyester - The supply - demand strong expectation of PX is weakened, and the valuation is under pressure. The processing margin and basis of PTA have been repaired, but the industry profit is still poor. Pay attention to the possibility of polyester inventory reduction due to downstream stocking [4]. - The price of ethylene glycol has been falling, with weak expectations. The short - fiber price has followed the raw materials and the external sentiment to decline, and the near - month contract can be allocated bullishly. The bottle - chip industry has over - capacity, and the expected processing margin repair space is limited [4]. Coal Chemical Industry - The methanol futures hit a new low.
