Core Views - The chemical market shows complex trends with different product performances. Some products are affected by factors such as device maintenance, demand changes, and supply - demand imbalances [2][3][5]. - There are differences in the performance of the spot and futures markets, and the basis has changed in some products [2][3]. - The supply - demand relationship is a key factor affecting prices, with some products facing supply - demand contradictions [2][3][5] 3. Summary by Relevant Catalogs Olefins - Polyolefins - Propylene prices continued to rise due to early - started planned maintenance of a device in Dongying during the National Day holiday and the gradual recovery of some downstream demand. However, the futures price fell on the first trading day after the holiday, resulting in a divergence between the spot and futures markets and an enlarged basis [2]. - Polyolefins faced a situation of weak peak - season demand, mainly with rigid procurement. The large - scale release of new production capacity led to a significant increase in domestic output, resulting in prominent supply - demand contradictions. There was inventory accumulation during the holidays, and there was obvious pressure to reduce inventory after the holidays, causing price pressure [2] Pure Benzene - Styrene - During the National Day, the oil price dropped, and the pure benzene futures once fell below 5700 yuan/ton in the morning session and then rebounded with the oil price in the afternoon. The spot price in East China was weak, the shipment in Shandong was dull, and Sinopec's listed price remained stable. The device operation rate continued to rise, and the port inventory decreased. However, high imports and expected demand decline continued to drag down the market [3]. - The main contract of styrene futures closed slightly lower, with the overall center of gravity moving down along the 5 - day moving average. The oil price during the holiday was basically the same as before the holiday, having limited impact on the cost of styrene. The demand was weak during the peak season, and the supply increased significantly due to the expansion of production capacity. The inventory of styrene has been significantly higher year - on - year since this year and has shown a trend of oscillating inventory accumulation after June, suppressing the price [3] Polyester - During the holiday, the overseas oil price dropped, causing the prices of PX and PTA to weaken in the morning and then recover with the rebound of the oil price in the afternoon. The operation rate of PX continued to increase. Hengli Dalian's PTA carried out maintenance, and some East China devices reduced their loads due to reasons. In the short term, PX was under pressure, and the PTA link repaired its profit. However, in the future, the PX of Wushi Petrochemical plans to carry out maintenance, and the polyester load is expected to remain stable. The near - term supply - demand pattern of upstream raw materials is okay, and attention should be paid to terminal orders and raw material restocking. In mid - to late October, the downstream demand is expected to gradually weaken, and the supply - demand situation will still be under pressure in the long - term [5]. - The domestic operation rate of ethylene glycol increased significantly, and the port inventory accumulated significantly during the holiday, with a weak fundamental situation. The main futures price once approached the 4100 yuan/ton mark. In the medium - term, with the mass production of new devices and the weakening of future demand, the supply - demand situation will gradually weaken in the fourth quarter, and the 1 - 5 spread is under downward pressure [5]. - The new production capacity of short - fiber is limited, and the operation rate is at a high level. The terminal weaving and dyeing industries increased their operation rates, and the recovery of peak - season demand boosted the short - fiber industry. It is recommended to be long in the short - term, and attention should be paid to downstream orders and short - fiber inventory [5]. - The operation rate of bottle chips increased, but after the long holiday, with the cooling weather, the demand is expected to weaken. Overcapacity is a long - term pressure, and the processing margin is under continuous pressure [5] Coal Chemical Industry - The methanol futures price dropped significantly. During the holiday, the import volume remained high, and the port inventory continued to accumulate. The capacity utilization rate of domestic methanol devices increased. Before the holiday, inland olefin enterprises carried out centralized external procurement, and enterprises had sufficient pending orders, but the order execution was slowed down due to logistics restrictions, and the inventory of production enterprises increased slightly. Imports are expected to remain sufficient, and the port is expected to continue to accumulate inventory. The near - term situation is weak, while the far - month outlook is relatively strong. Attention should be paid to factors such as macro - sentiment and overseas device changes [6]. - During the National Day holiday, urea production enterprises significantly accumulated inventory, with high supply and great pressure on enterprise shipments. Affected by factors such as weather and logistics, the downstream demand was insufficient. Export orders were being shipped, and the port inventory decreased. Although India issued a new round of urea tenders, planning to import 2 million tons, the export window period may have ended, and the short - term boost to the market is limited. The pattern of loose domestic supply - demand of urea is difficult to change, and attention should be paid to possible policy adjustments and their impact on market sentiment [6] Chlor - Alkali Industry - The main contract of PVC dropped. During the holiday, the downstream demand weakened, the supply was at a high level, and the inventory increased significantly. After the end of maintenance and the release of new production capacity, the supply pressure was high. The downstream's intention to stock up was not high, and the industry continued the inventory - accumulation mode. The chlor - alkali integration still had profits, and the cost support was not obvious. PVC may show a weak - oscillating trend [7]. - The caustic soda futures dropped significantly. There was still the phenomenon of vehicle detention by downstream buyers, and the purchase price may be further reduced, with the inventory increasing compared with the previous period. There are small - scale maintenance plans for caustic soda in North China and East China in October, and the supply is still under high - pressure operation due to remaining profits. The liquid - caustic soda inventory of alumina plants in Shanxi and Henan is high, and the downstream profit is shrinking, with resistance to high prices. The weak - reality pattern continues, but the strong expectation of possible restocking demand before the future downstream alumina production cannot be falsified. It is recommended to wait and see [7] Soda Ash - Glass - The price of soda ash futures was weakly operating. Before the holiday, the inventory was mainly reduced, and it increased after the holiday. The rigid demand for heavy soda was stable. The production capacity of float glass and photovoltaic glass has been stable recently. The inventory of the photovoltaic industry has changed from decreasing to increasing, and it is expected that the ignition speed will slow down in the future, with limited incremental rigid demand for heavy soda. There are few maintenance plans in October, and the industry currently has little operating pressure, with high - pressure supply. The long - term pattern of supply - demand surplus remains unchanged, and opportunities to short at high prices should be sought, but caution should be exercised near the cost [8]. - The price of glass futures fluctuated narrowly. During the holiday, downstream enterprises had holidays, and the production and sales were insufficient, with seasonal inventory accumulation in the industry. Some regions raised their quoted prices. The daily melting volume was oscillating at a relatively high level. The processing orders improved but were still insufficient on a month - on - month basis, and some engineering orders increased. The situation of whether Shahe will centrally use Zhengkang's deep - processed gas should be continuously tracked. If the production - capacity reduction does not actually occur, the market may return to weak - reality trading, but with the current low valuation, the decline is expected to be limited. A low - buying strategy near the cost can be considered in the future [8]

One star means a bias towards long/short with a driving force for an upward/downward trend but limited operability on the trading floor. Two stars mean holding long/short with a clearer upward/downward trend and the market condition is evolving. Three stars mean an even clearer long/short trend and there are still relatively appropriate investment opportunities. White stars mean the short-term long/short trend is in a relatively balanced state and the current trading floor has poor operability, suggesting a wait-and-see approach [1][9] Core Views - The chemical market shows a complex situation with different trends in various sub - sectors. Some products are affected by factors such as supply - demand imbalances, seasonal changes, and raw material price fluctuations [2][3][5] Summary by Related Catalogs Olefins - Polyolefins - Propylene prices continued to rise due to early planned maintenance of a device in Dongying during the National Day holiday and the gradual recovery of some downstream demand. However, the futures price fell on the first trading day after the holiday, resulting in a divergence between the futures and spot markets and an expansion of the basis. - For polyolefins, the peak season demand was weak, with mainly rigid demand procurement. The large - scale release of new production capacity on the supply side led to a significant increase in domestic production this year, resulting in prominent supply - demand contradictions. Production enterprises accumulated inventory during the double festivals, and there was obvious pressure to reduce inventory after the holiday, causing prices to be under pressure [2] Pure Benzene - Styrene - During the National Day, the oil price fell. The pure benzene futures price once dropped below 5700 yuan/ton in the morning session and then rebounded following the oil price in the afternoon. The spot price in East China was weak, the shipment in Shandong was dull, and the listed price of Sinopec remained stable. The device operation rate continued to rise, the port inventory decreased, the actual fundamentals were okay, but the basis weakened compared to before the holiday. High import volume and the expectation of future demand decline continued to drag down the market. - The main contract of styrene futures closed slightly lower within the day, and the overall center of gravity moved down along the 5 - day moving average. The oil price first decreased and then increased during the holiday, remaining basically the same as before the holiday, having limited impact on the cost side of styrene. On the supply - demand fundamentals, the peak season demand was weak. Due to the expansion of production capacity, the domestic supply increased significantly. The total inventory of styrene has been significantly higher year - on - year since this year, showing a trend of oscillatory inventory accumulation after June. The supply - side pressure was large, suppressing the styrene price, and the styrene market was in a bearish pattern [3] Polyester - The overseas oil price fell during the holiday. The prices of PX and PTA weakened in the morning session and then rebounded in the afternoon due to the oil price recovery. The operation rate of PX continued to increase. Hengli Dalian's PTA carried out maintenance, and the East China device reduced its load due to an accident. In the short term, PX was expected to be under pressure, and the PTA segment repaired its profit. However, the PX of Wushi Petrochemical was planned for maintenance, and the polyester load was expected to be maintained. The short - term supply - demand pattern of upstream raw materials was okay. Attention should be paid to terminal orders and raw material restocking. In mid - to late October, the downstream demand was expected to gradually weaken, and the supply - demand situation would still be under pressure in the long run. - The domestic operation rate of ethylene glycol increased significantly, and the port inventory accumulated significantly during the holiday. The fundamentals were weak, and the main futures price once approached the 4100 yuan/ton mark within the day. In the medium term, with the mass production of new devices and the weakening of future demand, the supply - demand situation would gradually weaken in the fourth quarter. Under the expectation of inventory accumulation, the 1 - 5 spread was under pressure to decline. - The new production capacity of short fiber was limited, and the operation rate was at a high level. The terminal weaving and dyeing industries increased their operation rates. The recovery of peak - season demand boosted the short - fiber industry. It was recommended to continue to be long in the short term. Attention should be paid to downstream orders and short - fiber inventory. The operation rate of bottle chips increased, but after the long holiday, as the weather turned cooler, the demand was expected to weaken. Overcapacity was a long - term pressure, and the processing margin was continuously under pressure [5] Coal Chemical Industry - The methanol futures price dropped significantly. During the holiday, the import volume remained high, and the port inventory continued to accumulate. The capacity utilization rate of domestic methanol devices increased. Before the holiday, inland olefin enterprises made large - scale external purchases, and enterprises had sufficient orders to be delivered, but the order execution was slowed down due to logistics restrictions, and the inventory of production enterprises increased slightly. The import was expected to remain sufficient, the port was expected to continue to accumulate inventory, and the short - term weakness would continue. The long - term outlook was relatively positive. Attention should be paid to macro - sentiment and changes in overseas devices. - During the National Day holiday, urea production enterprises significantly accumulated inventory, the supply remained high, and enterprises faced great pressure to sell. Affected by weather and logistics factors, the downstream demand was insufficient. Export orders were being shipped, and the port inventory decreased. Although India issued a new round of urea tenders, planning to import 2 million tons, the export window period might have ended, so the short - term boost to the market was limited. The domestic supply - demand situation of urea remained loose. Attention should be paid to possible policy adjustments and their impact on market sentiment [6] Chlor - alkali Industry - The main contract of PVC dropped. During the holiday, the downstream demand weakened, the supply was at a high level, and the inventory increased significantly. After the end of maintenance and the release of new production capacity, the supply pressure was high. The downstream's intention to stock up was low, and the industry continued the inventory - accumulation pattern. The integrated chlor - alkali enterprises still had profits, but the cost support was not obvious. In a weak real - situation pattern, PVC might show a weak - oscillatory trend. - The caustic soda futures price dropped significantly. There were still vehicle - waiting phenomena among downstream buyers, and the purchase price might be further reduced. The inventory increased compared to the previous period. There were maintenance plans for caustic soda in North and East China in October, but the scale was small. Since there were still profits, the supply was still operating at a high level. The liquid caustic soda inventory of alumina plants in Shanxi and Henan was high, and the downstream profit margin shrank. They were resistant to high - priced products. The weak real - situation pattern continued, but there might be restocking demand before the future downstream alumina production. Since the strong - expectation could not be falsified, it was recommended to wait and see [7] Soda Ash - Glass - The soda ash futures price was in a weak state. The inventory decreased before the holiday and increased after the holiday. The rigid demand for heavy soda was stable. The production capacity of float glass and photovoltaic glass has been stable recently. The inventory of the photovoltaic industry increased after a decrease. It was expected that the ignition speed would slow down in the future, and the incremental rigid demand for heavy soda was limited. There were few maintenance plans in October, the industry's current operating pressure was not large, and the supply would operate at a high level. The long - term supply - demand surplus situation remained unchanged. Opportunities to short at high prices should be sought, but be cautious when approaching the cost level. - The glass futures price fluctuated within a narrow range. During the holiday, downstream enterprises had holidays, and the production and sales were insufficient. The industry seasonally accumulated inventory, and some regions increased their quoted prices. The daily melting volume was oscillating at a relatively high level. The processing orders improved but were still insufficient on a month - on - month basis, and some project orders increased. Whether Shajiahe would intensively use Zhengkang's deep - processed gas should be continuously monitored. If the production - capacity reduction does not actually occur, the market may return to the weak - real - situation trading. However, with the current low valuation, the expected decline range is also limited. In the future, a low - buying strategy near the cost level can be considered [8]

Report Industry Investment Ratings No relevant content provided. Core Views Methanol - The current market's core trading logic revolves around "high inventory + high imports." Port arrivals remain high, leading to significant inventory accumulation. Combined with a weakening trading atmosphere, prices are showing a downward trend. - Domestic supply is at a relatively high level year-on-year. Although there has been an increase in unplanned maintenance of some devices recently, there are expectations for some devices to resume production in early October. However, the inventory situation in the inland area is relatively healthy, providing some support for prices. - On the demand side, affected by the off - season of traditional downstream industries, overall demand is weak. In terms of valuation, upstream profits are at a neutral level, MTO profits have strengthened, and traditional downstream profits have slightly improved, resulting in an overall neutral valuation. - The current futures market is in a state of contention: on one hand, there is the real - world pressure of high inventory and weak basis; on the other hand, there is the expected support of overseas gas restrictions in the distant future. Attention should be paid to the emergence of an inventory inflection point [1]. Pure Benzene and Styrene - During the holiday, crude oil and naphtha prices both declined. Fundamentally, there are expectations for the resumption of production of some maintenance devices and the commissioning of new production capacity for pure benzene in the near future. Coupled with the expected increase in imports in the fourth quarter, domestic pure benzene supply is expected to remain at a relatively high level. - In terms of demand, most downstream pure benzene products are currently operating at a loss, and the secondary - downstream inventory of some products is high. There has been an increase in unplanned production cuts in some downstream industries, and there is significant uncertainty in demand growth, providing limited support. Overall, the supply - demand outlook for pure benzene remains loose, and the price driving force is weak. - For styrene, during the holiday, crude oil, naphtha, and styrene spot prices all declined. There are expectations for the commissioning of new devices and the resumption of production of previously shut - down devices after the holiday, so supply is expected to increase. Although there are still some devices planning to shut down, it is difficult to fully offset the pressure from new and resumed production. - On the demand side, there is rigid demand support during the downstream seasonal peak season, but the profits of some downstream industries are under pressure, and finished - product inventory remains high, so demand - side support may be limited. The supply - demand outlook for styrene is also loose, with high port inventory and weak cost - side support. After the holiday, styrene prices are expected to remain under pressure [3]. Polyolefins (LLDPE and PP) - PE maintenance has reached a peak, and the operating rate is gradually recovering. Inventory in the upstream and mid - stream has decreased this week. Future attention should be paid to the supply rhythm and import offers. - Before the holiday, the CP settlement price decreased, and PDH device profits were restored. Future attention should be paid to the resumption of PP devices. - On the demand side, there are no bright spots. After the holiday, there is significant inventory pressure. Coupled with the launch of new production capacity, there is a large pressure for inventory accumulation in the 01 contract, which limits the upside potential [5]. PVC and Caustic Soda - For caustic soda, most mid - and downstream enterprises were on holiday during the festival, and there was no obvious fluctuation in the spot market. Before the holiday, the futures market continued to weaken. After the National Day, as non - aluminum inventory is digested and decreases, there may be some purchasing willingness due to low prices. - The downstream inventory of the main alumina producers is high, and the willingness to replenish inventory is also low. The delivery volume of large Shandong manufacturers was high before the holiday, and there is an expectation of a downward adjustment in future purchase prices. Alumina production capacity is at a high level, and there is an over - supply problem. It is expected that production cuts may not occur until January. Therefore, there is still some support for short - term caustic soda demand. - From the perspective of the commissioning schedule, there will be a large number of alumina commissionings in the first quarter of next year. Therefore, there may be concentrated inventory replenishment in the fourth quarter of this year, which may tighten the spot liquidity. It is expected that there is limited downside space for caustic soda in the future, and attention should be paid to the downstream inventory replenishment rhythm. - For PVC, most mid - and downstream enterprises were on holiday during the festival, and spot trading was light. Before the holiday, the PVC futures market weakened and fluctuated. The supply - demand contradiction in the fundamentals is still difficult to resolve, and both futures and spot prices are weakening. - On the supply side, production remains at a high level, and the over - supply situation is prominent. On the demand side, there has been no obvious performance during the peak season, and the demand for profiles has continued to shrink, showing obvious characteristics of a non - peak season. - Overall, the willingness of upstream producers to hold inventory has decreased. However, exports have alleviated some of the over - supply pressure. The cost of raw material calcium carbide is on an upward trend, and ethylene prices are stable, providing bottom - level support for costs. After the holiday, attention should be paid to cost support. It is expected that there is limited downside space for PVC during the peak season, and attention should be paid to downstream demand performance [7]. Polyester Industry Chain - For PX, during the holiday, international oil prices fluctuated within a range. The main trading logic was that OPEC + announced only a slight increase in production in January, which was lower than market expectations, temporarily alleviating supply pressure. Currently, the domestic PX operating rate remains high. - On the demand side, due to continuously low PTA processing fees, the commissioning of new PTA devices has been delayed, and there are maintenance expectations for multiple PTA devices. The supply - demand outlook for PX in the fourth quarter is weak, and there is an expectation of PXN compression. The overall trend during the National Day holiday was weak. It is expected that PX will continue to fluctuate weakly after the holiday. - For PTA, due to continuously low processing fees, the commissioning of new PTA devices has been postponed, and there are maintenance expectations for multiple PTA devices. Some devices have reduced or stopped production due to the impact of typhoons, so PTA supply is expected to contract. - Coupled with the pre - holiday downstream inventory replenishment demand, the PTA basis has been slightly repaired, but the expected upward space is limited. The overall trend during the National Day holiday was weak. It is expected that the driving force for PTA after the holiday will be limited, and it will continue to fluctuate weakly. - For ethylene glycol, during the holiday, there were many foreign - owned vessel arrivals. It is expected that port inventory will increase significantly after the holiday. In addition, the restart of the Satellite Petrochemical device and the commissioning of the new Yulong Petrochemical device in October will keep domestic supply at a high level, and the supply - demand situation will gradually weaken. Therefore, it is expected that there will be upward pressure on ethylene glycol after the holiday. - For short - fiber, the supply - demand pattern is weak. Currently, short - fiber supply remains at a high level. On the demand side, the market replenished inventory before the holiday, and the inventory of directly - spun polyester short - fiber has been continuously decreasing. It is expected that short - fiber will be relatively more supported than raw materials in the short term, but the driving force is limited, and its rhythm will mainly follow the raw materials. - For bottle - grade polyester chips, there is no news of further production cuts in October. The fourth quarter is the traditional off - season for bottle - grade polyester chips. Considering the gradual cooling of the weather in October, the demand for soft drinks and catering will decline slightly, and the demand side provides insufficient support. Therefore, bottle - grade polyester chips are likely to enter a seasonal inventory - reduction channel, and PR will mainly follow the cost side, with upward pressure on processing fees [8].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - OPEC shows a hesitant attitude with a slightly stronger willingness to support prices than to expand market share, and the slight increase plan will continue to suppress the upside space of oil prices. Crude oil is expected to remain volatile in the short term [1]. - The fundamentals of methanol have marginally improved, and the downside space is expected to be relatively limited. It is recommended to focus on short - long opportunities on dips [3]. - Urea is currently in a situation of low valuation and weak drivers. With no effective positive factors in reality, it is suggested to focus on going long on dips at low prices [5]. - For rubber, the medium - term view is bullish, but it has broken down in the short term. It is recommended to set stop - losses and enter short - long positions opportunistically, and to partially re - establish the hedge position of buying RU2601 and selling RU2511 [12]. - The fundamentals of PVC are poor, with strong domestic supply and weak demand, and the export outlook is weak. In the short term, the valuation has declined to a low level, and it is recommended to focus on short - selling opportunities on rallies in the medium term [14]. - The spot and futures prices of pure benzene and styrene are falling, and the basis is weakening.
