1. Report Industry Investment Rating No information about the industry investment rating is provided in the reports. 2. Core Views of the Reports Polyester Industry - PX: Before the geopolitical situation eases, the cost support for PX is strong, and there is an expectation of significant de - stocking. Strategy: stage - low long positions and use put options for hedging; go long on the PX9 - 1 spread at a low level; widen the PXN spread when there are signs of geopolitical easing [1]. - PTA: In the second quarter, PTA has limited self - drive, and its absolute price follows the cost. Strategy: stage - low long positions and use put options for hedging; look for high - level reverse spread opportunities for the PTA9 - 1 spread [1]. - Ethylene Glycol: In the second quarter, affected by the Middle East situation, the cost support is strong, and there is a significant de - stocking expectation. Strategy: before the Middle East oil transportation recovers, EG may rise, but beware of pull - backs; lightly buy EG call options [1]. - Short - fiber: In the second quarter, short - fiber has weak self - drive and follows the raw materials. Strategy: the same as PTA for the single - side position; try to widen the spread when the PF processing fee is below 800 [1]. - Bottle - chip: In the second quarter, the supply - demand of bottle - chips is expected to be tight, and the processing fee is expected to be strong. Strategy: the same as PTA for the single - side position; the processing fee of the main contract is expected to be strong; lightly buy PR call options [1]. Urea Industry In March, the urea market showed a trend of rising first and then stabilizing. In April, the supply may decrease slightly in the first half of the month, and the demand will weaken slightly. The price may be firm in the first half of the month and may decline in the second half [2]. PVC and Caustic Soda Industry - Caustic Soda: In March, the price of caustic soda showed a trend of rising after a slight decline. In April, the price increase may be limited [3]. - PVC: In March, the average monthly price of PVC increased. In April, the average monthly price is expected to move up slightly, but the recovery of the real estate market and slow inventory de - stocking may limit the increase [3]. Natural Rubber Industry The supply pressure from the opening of the rubber - tapping season and the support from high overseas costs and geopolitical events will lead to wide - range fluctuations in rubber prices, with an expected operating range of 15,500 - 17,500. Pay attention to the follow - up development of the US - Iran conflict [4]. Methanol Industry The current market is driven by the supply gap caused by the escalation of the Middle East geopolitical conflict. The methanol fundamentals have improved, and it is easy to rise and difficult to fall [5]. Crude Oil Industry The main factors affecting oil prices are geopolitical support and policy suppression. If the situation does not improve, there is still upward momentum in the short - term. In the long - term, pay attention to the impact of high oil prices on inflation, the economy, and energy substitution [8]. Pure Benzene and Styrene Industry - Pure Benzene: The supply is expected to decrease, and the supply - demand is expected to improve. In the short - term, it may follow the oil price. Strategy: wait and see; narrow the EB05 - BZ05 spread when it is high [10]. - Styrene: The supply - demand is still tight. In the short - term, the absolute price follows the oil price. Strategy: the same as pure benzene [10]. LPG Industry The LPG market is affected by factors such as price changes, inventory, and upstream and downstream operating rates. The overall situation needs to be comprehensively analyzed based on various factors [11]. Glass and Soda Ash Industry - Soda Ash: In the second quarter, the price may further decline due to factors such as increased supply and weak demand. Pay attention to the support at around 1150 for SA605 [12]. - Glass: Affected by multiple factors such as weak supply - demand, high inventory, and cost expectations, pay attention to the recovery of demand and inventory de - stocking [12]. Polyolefin Industry The polyolefin market is trading around the logic of "strong cost and reduced supply". The 05 - contract inventory is expected to be low. In April, the supply and cost support will be further strengthened [13]. 3.

1. Report Industry Investment Rating - No industry investment ratings are provided in the reports. 2. Core Views Rubber Industry - The market sentiment has eased with the expectation of a cease - fire and peace talks between the US and Iran, leading to a halt in the decline and a rebound in rubber prices. However, as the domestic rubber - producing areas are fully tapped, supply pressure will gradually dominate the market, and rubber prices are expected to remain under pressure. Attention should be paid to the subsequent development of the US - Iran conflict [2][4]. Urea Industry - The urea futures market is volatile, and the spot price has risen slightly. The current situation of strong supply and weak demand is difficult to change in the short term, and the spot market deviates from the futures. The supply remains in a loose pattern, and demand is generally cautious. Policy factors suppress prices, and the short - term rise in futures driven by emotions cannot be transmitted to the spot market. The urea market is highly volatile in the short term due to the expected escalation of the Middle East conflict [5]. PVC and Caustic Soda Industry - For caustic soda, the supply has further decreased this week, the profit has increased significantly, and the export expectation is high. Although the downstream demand has improved, the overall supply - demand pattern is still weak. The price has been affected by the Middle East conflict and has fluctuated sharply, and it has fallen recently as the market sentiment has ebbed. For PVC, the futures price has weakened, and the spot price has retreated from a high level. The ethylene - based PVC has a rising trend driven by cost, while the calcium - carbide - based PVC has insufficient upward momentum. The overall market price is likely to be difficult to fall, but regional trends and raw material prices should be carefully observed [6]. Glass and Soda Ash Industry - For glass, the spot price is stable, the supply has shrunk, and the demand is weak. The inventory has decreased slightly, and the market is expected to be a game between supply - demand fundamentals and cost support, with a weak and volatile trend. For soda ash, the supply - demand pattern of strong supply and weak demand continues. The weekly output has shown a declining trend due to equipment maintenance, and the downstream demand is mainly for rigid needs. The market is also expected to be volatile and weak [7]. Pure Benzene and Styrene Industry - For pure benzene, some Asian refineries' operations are affected, and the supply is expected to decline. The downstream product prices are rising, and the supply - demand expectation has improved. However, the short - term trend is dragged down by falling oil prices, and it may fluctuate with oil prices. For styrene, the overall supply is expected to remain stable, and the supply - demand situation is still tight. The profit has been continuously compressed due to the sharp rise in raw material ethylene prices, and the absolute price also fluctuates with oil prices [8]. Methanol Industry - The methanol market is highly volatile due to geopolitical conflicts. The supply side shows an increase in domestic production and a possible decrease in imports. The demand side has a warming expectation for MTO demand in ports. Currently, the decrease in imports dominates the market, but the sustainability of demand and policy risks should be noted [9]. LPG Industry - No specific core view is provided in the report, but price and inventory data show that LPG prices have fallen, and the inventory of refineries and ports has increased. The upstream refinery operating rate has decreased, and the downstream PDH operating rate has increased [10]. Crude Oil Industry - The current conflict in the Middle East has entered the fourth week, and the focus is on the control of the Strait of Hormuz and energy supply chain security. The market sentiment has eased, but there are doubts about the negotiation and cease - fire. The oil price is expected to maintain a wide - range shock, mainly supported by geopolitics and suppressed by policies. Short - term attention should be paid to the actual通航 recovery of the Strait of Hormuz and the progress of negotiations [11]. Polyester Industry Chain - For PX, the supply is expected to decrease further, and the downstream polyester has a cost - transmission problem, resulting in a situation of weak supply and demand. The short - term trend is dragged down by falling oil prices. For PTA, there is an inventory - accumulation expectation, and the absolute price fluctuates with the cost side. For ethylene glycol, the cost support is strong, the supply has decreased significantly, and the price has the momentum to rise. For short - fiber, the supply - demand situation has weakened, and it mainly fluctuates with raw materials. For bottle - chips, the supply is expected to be tight, and the processing fee of the main contract is expected to be strong [13]. Polyolefin Industry - Affected by the expectation of possible negotiations between the US and Iran, the polyolefin futures market has fallen significantly, and the basis has strengthened passively. The current fundamentals are based on the logic of "strong cost and reduced supply", but the downstream demand is limited. The unilateral price fluctuates greatly, and long - positions can be reduced [14]. 3. Summary by Directory Rubber Industry - **Spot Prices and Basis**: The prices of various rubber products have shown different degrees of changes, such as the increase in the price of Yunnan state - owned whole latex and the decrease in the price of natural rubber blocks in Xishuangbanna.

Group 1: Report Industry Investment Ratings - No investment rating information provided in the reports Group 2: Core Views Polyolefins - The current market is in a fierce game between strong cost support, supply contraction expectations, and weak actual demand. It is expected that prices will maintain a wide - range high - level shock. If the geopolitical tension continues, under the combination of "domestic production cuts, reduced imports, and increased exports", and the conflict tends to be long - term, the domestic start - up rate may decline further after April, and the 05 contract is expected to have a significant upward market [1]. Rubber - The Sino - US conflict remains stalemate, and the crude oil price fluctuates at a high level. In the short term, the crude oil trend still dominates the market risk sentiment. The natural rubber fundamentals have both long and short factors, and it is expected to fluctuate within a range of 16,000 - 17,500, with strong cost support at the lower end. Be vigilant about the market trading the reduction of Middle - East tire demand again at the upper end of the price range [2]. Glass and Soda Ash - Soda ash: The fundamental pattern of strong supply and weak demand continues. In the short term, multiple production lines are planned for maintenance. In the medium - to - long term, there is still some room below the current price. It is expected that the futures will be in a shock - adjustment pattern, with a reference range of 1150 - 1300. It is recommended to wait and see unilaterally, and pay attention to inventory and production line changes. - Glass: The current supply - side daily melting volume is already low, and the real - estate data shows that the real - estate is still in the adjustment period, and the demand - side recovery is slow. The overall fundamentals have weak supply and demand. It is advisable to view it with a shock outlook. The strategy is to wait and see, with a reference range of 1000 - 1150. Pay attention to inventory and downstream demand [3]. PVC and Caustic Soda - Caustic soda: Although the fundamentals have marginally improved, the overall pattern of weak supply and demand remains unchanged. Recently, the Middle - East situation has slightly eased, and after the emotional tide recedes, the futures price has declined. - PVC: In the short term, the supply - demand situation has slightly changed. Affected by the expected increase in ethylene supply tension, the production load of ethylene - based production enterprises may be reduced in the long term, while the calcium - carbide - based production load has slightly increased. The cost increase drives the bottom of the PVC price to rise. The domestic demand is normal, and foreign trade exports are waiting for new quotes due to unstable freight and other risks [4]. Urea - The current urea fundamentals have not improved significantly. In the short term, urea prices are mainly subject to fluctuations driven by energy costs. Recently, the tense situation of high oil prices has slightly eased. Under the background of domestic price - stabilizing policies, urea may experience a shock - decline in the short term [5]. Ester Industry Chain - PX: In the short term, the supply and demand of PX are both weak, and the overall supply - demand is marginally weakening. The current benchmark price still dominates the chemical trend. Pay attention to the downstream negative feedback. It is expected that the absolute price of PX will fluctuate with the oil price in the short term. - PTA: In the short term, PTA's own driving force is limited, and the absolute price fluctuates with the cost side. - Ethylene glycol: In March, the domestic supply of ethylene glycol has significantly declined, and the arrival volume of foreign ships will be at a low level. The polyester load is seasonally rising, and the de - stocking amplitude is expected to expand in March - April. In the short term, the ethylene glycol price still has the momentum to rise. - Short - fiber: In the short term, the short - fiber's own driving force is limited, and it mainly follows the raw material fluctuations. - Bottle chips: The supply of domestic bottle chips is gradually increasing in March. Under the influence of macro and crude oil stimulation and the peak procurement season of PET, the downstream procurement of bottle chips is expected to follow up, and the supply - demand of bottle chips is expected to be tight [6]. Crude Oil - In the short term, the oil price maintains a pattern of "policy suppression + geopolitical support", and Brent maintains a range - bound fluctuation. If the Strait of Hormuz blockade lasts for more than a month, the supply will change from inventory depletion to a substantial shortage, and the oil price may still have strong upward momentum [8]. Pure Benzene and Styrene - Pure benzene: The supply of pure benzene is expected to decline, and the supply - demand is expected to improve. In the short term, pure benzene may follow the oil - price fluctuations. - Styrene: In March, the supply of styrene remains high, and the supply - demand is expected to slightly de - stock. In the short term, the absolute price of styrene follows the oil - price fluctuations [10]. Methanol - At present, the price is dominated by supply - interruption expectations and risk sentiment. The subsequent trend highly depends on the actual progress of the geopolitical conflict [11]. LPG - No overall core view provided for LPG in the report Group 3: Summary by Related Catalogs Polyolefins - **Prices**: Futures prices of L2605, L2609, PP2605, and PP2609 all declined on March 18 compared with the previous day, with declines ranging from 0.28% to 0.77%.

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Pure Benzene and Styrene - Due to the tense geopolitical situation, the supply of pure benzene is expected to decline, and the supply - demand outlook has improved. However, the price will fluctuate with oil prices. The strategy is to wait and see on a single - side basis and shrink the EB04 - BZ04 spread when it is high [1]. - The supply of styrene in March remains high, and the supply - demand is expected to slightly reduce inventory. The price will follow oil price fluctuations, and the strategy is the same as that for pure benzene [1]. Urea - The short - term price of urea is relatively firm, but there may be a downward trend after the return - green fertilizer season in mid - March, mainly affected by sentiment. The main contract should focus on whether it can break through the 1860 - 1900 range, and the strategy is to go long at low levels [2]. PVC and Caustic Soda - The short - term rise of caustic soda is due to the optimistic expectations from geopolitical conflicts. The supply - demand situation is still severe, and attention should be paid to the actual delivery volume of downstream and the price fluctuation of liquid chlorine [3]. - The price of PVC is expected to be passively pushed up. The supply - demand situation has slightly changed, and the cost - end transmission has uncertainties [3]. Natural Rubber - The new rubber supply is gradually being released, and the demand has uncertainties. The price is expected to fluctuate within the range of 16500 - 17500, and attention should be paid to the reduction of tire demand in the Middle East [4]. Glass and Soda Ash - The supply of soda ash is strong and the demand is weak, and it is affected by macro fluctuations. The market is expected to fluctuate, and the range is 1150 - 1300. The strategy is to wait and see on a single - side basis and consider the arbitrage of short soda ash and long glass [5]. - The supply of glass has a low daily melting volume, and the inventory has been well reduced. The strategy is to wait and see, with a range of 1000 - 1150, and go long at low levels after the macro situation stabilizes. Also, consider the arbitrage of short soda ash and long glass [5]. Polyolefins - The short - term market of LLDPE and PP is strong due to cost support, supply reduction, and demand recovery expectations. Attention should be paid to the sustainability of cost support and the actual procurement demand of downstream [6]. Methanol - The price of methanol is widely fluctuating due to geopolitical sentiment. The supply may have an actual reduction, the demand is gradually recovering, and the inventory has started to reduce. Attention should be paid to the progress of the conflict, the inventory reduction rhythm, and the implementation of maintenance [7]. Crude Oil - In the short term, oil prices will maintain a pattern of "policy suppression + geopolitical support", and Brent is likely to fluctuate in the range of 80 - 100 US dollars per barrel [8]. Polyester Industry Chain - For PX, the supply is expected to decline, but attention should be paid to the downstream negative feedback. The price will follow oil price fluctuations, and the strategy is to go long at low levels after the market stabilizes [10]. - For PTA, the self - driving force is limited, and the price follows the cost - end. The strategy is to wait and see on a single - side basis [10]. - For ethylene glycol, the supply in March has decreased significantly, and the inventory reduction amplitude may increase. The price has the momentum to rise, but attention should be paid to the risk of a sharp fall [10]. - For short - fiber, the supply - demand pattern is weak, and it follows the raw material fluctuations. The strategy is the same as that for PTA [10]. - For bottle - chips, the supply is expected to increase in March, and the supply - demand is expected to be tight. The strategy is the same as that for PTA [10]. LPG No specific view statement provided. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - **Polyolefin Industry**: The intraday disk and spot prices fluctuated greatly, and trading weakened. The upgrading of the geopolitical situation in the Middle East pushed up international oil prices, strongly boosting the market from the cost side. The supply side showed differentiation, with high domestic PE supply and increased losses in oil - based and naphtha - based routes; PP production was slow due to planned maintenance in March and rising raw material prices. The demand side was affected by the Spring Festival holiday, with downstream factory operating rates at a seasonal low. Although the current industry profit is in a historically low range and the real - world fundamentals are under pressure, the market has strong expectations for post - holiday restocking demand from downstream concentrated resumption of work. [1] - **Methanol Industry**: Methanol futures fluctuated widely, and spot and near - month contracts were purchased on - demand. The overall trading for the day was okay. The escalation of the Middle East conflict and shipping disruptions in the Strait of Hormuz limited Iranian methanol exports, triggering market concerns about a global supply interruption and a significant increase in geopolitical risk premiums. Fundamentally, domestic operating rates remained high, but the import side was affected by the geopolitical conflict, with increased instability of facilities and a significant decline in March arrivals. The demand side was weak, with poor olefin demand at ports and a delay in the start - up of new MTO plants. Port inventories were at a historically medium - high level, but there were expectations of destocking due to the expected reduction in imports. [3] - **Crude Oil Industry**: Overnight, the WTI April contract closed at $81.01 per barrel, up 8.51%, and the Brent May contract closed at $84.48 per barrel, up 3.78%. The sharp increase in freight rates made the delivery cost of SC futures more than $15 above Brent, and the domestic premium continued to rise. If the passage through the Strait of Hormuz remains blocked, oil prices will continue to rise significantly; if the Strait of Hormuz resumes normal passage, oil prices will face the risk of a large - scale return of geopolitical and freight insurance premiums. Historically, the impact of geopolitical conflicts on oil prices is mostly short - lived. After four consecutive days of sharp increases, long positions should be held with caution. [5] - **Urea Industry**: On the 5th, urea futures declined after reaching a high, and spot prices remained weak. The supply side had a slight increase in the operating rate this week, with daily production exceeding 220,000 tons, resulting in short - term supply pressure. The demand side had stable demand for agricultural green - turning fertilizers, and the demand for industrial compound fertilizers and board factories was gradually recovering. Affected by the domestic urea guidance price limit and the lack of new export news, the market was mostly on the sidelines regarding high prices, and downstream factories mostly purchased on - demand. In the short term, urea prices are expected to continue to trade in a high - level consolidation range. [8] - **PVC and Caustic Soda Industry**: On the 5th, caustic soda futures hit the daily limit, and spot prices remained stable overall. High - concentration caustic soda exports showed a good trend, and the production of 50% caustic soda in the province had not fully recovered, so high - concentration caustic soda may have a certain upward trend in the short term. The supply side had a slow recovery of caustic soda plant loads, and there was still pressure on industry inventory accumulation. The demand side had stable demand from the main alumina downstream and an improvement in non - aluminum downstream demand, which supported the caustic soda price. The increase in liquid chlorine prices further improved the comprehensive profits of chlor - alkali enterprises. PVC spot and futures prices fluctuated upward. The supply side maintained a high level, and domestic demand was normal. Foreign trade exports were affected by unstable freight rates and were waiting for new quotes. The cost - end transmission from crude oil - ethylene - PVC was uncertain, and the market sentiment was affected by concerns about energy. [9] - **Glass and Soda Ash Industry**: The futures of soda ash main contract SA605 oscillated upward, closing at 1,225 yuan/ton. The supply side had a slight increase in weekly production, and there were expectations of supply contraction due to shutdown and maintenance. The demand side had a general trading atmosphere, with low - price transactions being the main focus. The inventory in factories reached a new high. In the current situation of weak demand and high inventory, caution should be exercised regarding upstream manufacturers. The futures of glass main contract FG605 increased slightly, closing at 1,055 yuan/ton. The downstream resumption of work was less than expected, and the trading atmosphere was light. The supply side had a low daily melting volume, and the demand side was restricted by weather and environmental protection policies, with delayed full - scale resumption of work and mainly inventory digestion after resumption. The inventory of production enterprises continued to accumulate significantly. [10] - **Natural Rubber Industry**: On the supply side, overseas raw material prices have been rising weakly recently, and with the approaching of the domestic production area tapping window, the market's expectation of new supply has increased. On the demand side, the semi - steel tire market was relatively stable, with post - holiday regular restocking in the domestic market, and individual dealer order fairs boosting channel purchase demand, and a significant increase in terminal retail sales volume; exports were affected by the weakening of the European and Middle Eastern markets, but the EU has not yet implemented a temporary anti - dumping tax, and overall orders still had resilience. The all - steel tire domestic market had concentrated restocking, and dealer order fairs boosted purchase enthusiasm, with good overall channel purchase sentiment; exports were under significant pressure, and the shipment to the Middle East and European markets weakened. Overall, although the domestic restocking of all - steel tires provided short - term support, the drag of overseas geopolitical risks on tire exports was more persistent, and the demand side generally suppressed rubber prices. However, geopolitical conflicts also made BR difficult to fall and provided some positive support to rubber prices. In the short term, rubber prices are expected to oscillate. [11] - **LPG Industry**: The prices of LPG futures contracts declined. The inventory of LPG refineries and ports increased, and the operating rates of upstream and downstream industries showed different trends. The upstream main refinery operating rate remained unchanged, the sample enterprise weekly production - sales rate decreased slightly, the downstream PDH operating rate decreased, and the MTBE and alkylation operating rates remained stable. [13] - **Pure Benzene - Styrene Industry**: Affected by geopolitics, the transportation of crude oil has been blocked recently, and the operating expectations of Asian refineries have been affected. Some domestic and foreign refineries have made defensive load adjustments, and combined with some device maintenance plans, the supply of pure benzene is expected to decline. The profit of the downstream styrene industry has been significantly repaired, and the load has remained at a relatively high level, with strong short - term demand support. Although the supply - demand expectations of pure benzene have improved, due to the remaining import pressure and the high inventory at ports, the self - driving force of pure benzene is still limited, and its price follows the fluctuations of oil prices and downstream styrene. For styrene, due to good industry profits, the load of styrene factories has increased significantly. In March, some styrene devices are expected to restart, but there are also some device maintenance plans, so the supply increase in March is expected to be limited. The demand side has a gradual recovery of post - holiday downstream demand, and combined with previous export shipments, the supply - demand of styrene in March is expected to have a slight destocking. Recently, oil prices have been strong due to the boost of the Middle East geopolitical situation, and combined with the blocked export of styrene from the Middle East due to transportation, domestic styrene has new export orders, and it is expected to be boosted in the short term. [16] - **Polyester Industry Chain**: Affected by geopolitics, some domestic and foreign refineries have made defensive load adjustments, and the supply of PX is expected to decline. Starting from March, some domestic and foreign maintenance plans will be implemented one after another. Combined with the early restart or load increase of some TA devices due to improved processing fees after the holiday, the supply - demand expectations of PX have improved. The Middle East geopolitical situation also provides cost - side support to PX, and PX is expected to be strong in the short term. After the holiday, the load of PTA has increased, and the March PTA device maintenance plan may be less than expected. Affected by the Middle East geopolitical situation, the sharp rise in oil prices has driven up the prices of the industrial chain, but the increase in the spot price of raw material PX is greater, and the PTA processing margin has been compressed. The short - term self - driving force of PTA is limited, and its absolute price follows the cost - side fluctuations. The Middle East geopolitical situation is tense, and the short - term crude oil price is expected to continue to rise, which enhances the cost support for ethylene glycol. In March, the domestic supply of ethylene glycol will significantly decline, and the arrival volume of foreign ships will be at a low level from mid - March. At the same time, the polyester load will seasonally recover in March, and ethylene glycol is expected to have a slight destocking. Currently, the supply and demand of short - fiber are both weak. The short - term driving force of short - fiber is weak, and it mainly follows the fluctuations of raw materials. For bottle - chips, the domestic supply will gradually increase in March, and the terminal demand is in the recovery stage, with weakening expectations. The absolute price of bottle - chips still follows the cost - side fluctuations, but the processing fee may decline. [17] 3.

The caustic soda industry operating rate increased slightly, the PVC total operating rate remained unchanged, and the inventory of caustic soda factories increased, while the inventory of PVC upstream factories and total social inventory decreased slightly. [9] - **Outlook**: For caustic soda, short - term market increases are mainly due to optimistic expectations brought by geopolitical conflicts, and caution should be exercised regarding the decline of the disk after the easing of the situation. For PVC, the supply - demand is in a stalemate, and prices may be passively pushed up due to concerns about the cost side. [9] Glass and Soda Ash Industry - **Price and Inventory Changes**: The prices of glass and soda ash futures increased. The supply of soda ash increased slightly, and the inventory of soda ash factories increased. The supply of glass was at a low level, and the inventory of glass production enterprises continued to accumulate.

The operating rates of different links in the industrial chain showed different trends. [16] - **Outlook**: For pure benzene, pay attention to the risk of price drops after reaching a high, and roll low - buying. For styrene, it is expected to be strong in the short term, and also pay attention to the risk of price drops after reaching a high and roll low - buying. [16] Polyester Industry Chain - **Price and Inventory Changes**: The prices of upstream raw materials and downstream polyester products increased. The inventory of MEG ports decreased slightly, and the expected arrival volume decreased. The operating rates of different links in the polyester industrial chain increased. [17] - **Outlook**: For PX, it is expected to be strong in the short term. For PTA, its absolute price follows the cost - side fluctuations. For ethylene glycol, it is expected to have a slight destocking in March. For short - fiber, it mainly follows the fluctuations of raw materials. For bottle - chips, the supply will increase in March, and the processing fee may decline. [17]

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Polyolefin Industry - Affected by the escalation of the Middle - East geopolitical situation, international oil prices have strongly risen, boosting the polyolefin market from the cost side. Polyethylene domestic supply remains high, and losses in oil - based and naphtha - based production routes have intensified this week. For polypropylene, planned maintenance in March is relatively high, and the resumption progress of PDH and other devices is slow due to rising raw material prices. Downstream factory开工率 is at a seasonal low. Although the current fundamentals are under pressure, there are still expectations for post - holiday restocking demand. Attention should be paid to the sustainability of cost support and the actual recovery of downstream开工率 [1]. Methanol Industry - The escalation of the Middle - East conflict has led to shipping disruptions in the Strait of Hormuz and limited Iranian methanol exports, increasing geopolitical risk premiums. Domestically, the开工 rate remains high, but imports are affected by the conflict, and the arrival volume in March will decline significantly. The demand side is weak, and port olefin demand is poor. Port inventories are at a medium - high historical level, but there are expectations of inventory reduction. The current price is mainly driven by geopolitical sentiment, and attention should be paid to the actual progress of the conflict and the port inventory reduction rhythm [3]. Chlor - alkali and PVC Industry - For caustic soda, the futures fluctuated weakly on the 2nd, and the spot price remained stable. The supply is expected to increase as downstream chlorine - consuming industries resume work, increasing inventory pressure. The demand side has some support for the price. Overall, the domestic caustic soda supply - demand situation is weak, and the market may fluctuate and adjust in the short term. For PVC, the futures fluctuated higher on the 2nd, and the spot price was weakly volatile. The supply remains high, and the demand is normal. The price is affected by cost concerns and macro - sentiment, and the short - term upward sentiment may continue, but the increase is uncertain [7]. Urea Industry - The urea futures fluctuated down on the 2nd. The supply is relatively sufficient in the short term, and the inventory accumulated during the holiday exerts pressure on the price. The agricultural demand is advancing, while the industrial demand is slowly recovering. The price may be in a high - level stalemate in the short term. The main contract is expected to be in the 1800 - 1900 range, and attention should be paid to downstream demand progress and inventory accumulation [8]. LPG Industry - The LPG prices showed an upward trend on March 2nd. The炼厂库容 ratio and port inventory increased. The upstream - main refinery开工率 remained unchanged, and the downstream - PDH开工率 decreased slightly. The market is affected by various factors, and no specific overall view is provided in the report [9]. Natural Rubber Industry - Overseas main production areas are transitioning to reduced production and suspension of tapping, with a shrinking total supply and rising raw material prices. Downstream tire enterprises are gradually resuming work, and the demand is expected to be boosted. The inventory in Qingdao is accumulating. With the strengthening of overseas raw material prices and the resumption of downstream production, and the impact of the tense Middle - East situation on oil prices, the rubber price is expected to rise, and previous long positions can be held. Attention should be paid to changes in the Middle - East situation [13]. Crude Oil Industry - The overnight WTI and Brent crude oil prices rose significantly. The Iranian Islamic Revolutionary Guard Corps' blockade of the Strait of Hormuz has increased the risk premium of crude oil. If the risk spreads or the Strait of Hormuz is blocked for a long time, oil prices will continue to rise; if the conflict eases, there is a risk of a sharp decline in oil prices. Geopolitical conflicts usually have a pulsed impact on oil prices, and long positions should be held with caution [16]. Pure Benzene and Styrene Industry - For pure benzene, domestic and international devices are operating stably, and the downstream styrene industry's profit has been significantly repaired. However, due to import pressure and high port inventories, the price follows oil prices and downstream styrene fluctuations. For styrene, the industry profit is good, and the factory load has increased. In March, the supply increase is expected to be limited, and the demand is gradually recovering. The price is expected to be boosted by oil prices in the short term. For both, long positions should be reduced at high levels, and attention should be paid to price pressure and oil price trends [17]. Glass and Soda Ash Industry - For soda ash, the supply is in high - level shock, the demand is weak, and the inventory has increased significantly. The price may fluctuate in the short term, and short - selling can be considered around 1200. For glass, the supply is at a low level, the demand is restricted, and the inventory is seasonally increasing. The price may also fluctuate, and short - selling can be considered around 1075. Attention should be paid to post - holiday macro - policies and downstream situations [18]. Polyester Industry - For PX, the supply - demand situation is expected to improve in March, and the price is supported by cost and oil prices. For PTA, the load has increased, but the processing margin has been compressed, and the price follows the cost.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Polyolefins - Polyolefin prices are strong due to capital rotation to the chemical sector and geopolitical tensions. The static fundamentals show a decline in both supply and demand, and inventory is being depleted. The upstream inventory is low, and producers are reluctant to lower prices. However, agents are selling at a loss, the basis has weakened significantly, and hedgers have no risk - free positions. For PP, the supply pressure is relieved due to many maintenance activities, and the PDH profit is still low, with a strong drive for production cuts. For PE, the pressure on standard products increases as India switches to LLD production, and the downstream demand enters the off - season, leading to a decline in downstream operating rates [1]. Pure Benzene and Styrene - The supply - demand situation of pure benzene has marginally improved, but the port inventory has increased unexpectedly, and the absolute level is still high. It is driven by oil prices and downstream styrene. With the increase in pure benzene and PX prices, the disproportionation profit has improved, and some units are expected to restart. The import of pure benzene is expected to increase. Overall, the supply - demand outlook is positive, but the driving force is limited, and it follows the fluctuations of raw materials and downstream styrene. For styrene, the short - term trend is strong due to limited market supply, strong oil prices, and capital inflows. However, the supply - demand outlook is weakening, and the port inventory has increased slightly. It is recommended to wait and see and shrink the EB - BZ spread when it is high [2]. Methanol - Methanol prices are rising, and the basis is weakening. The market is in a situation of weak supply and demand. The inland area maintains high production, and the inventory is slightly depleted. The port inventory is slightly decreasing, but the MTO demand is weak, which suppresses the price rebound. The key variables are the reduction rhythm of imported methanol from Iran and the risk premium caused by geopolitical factors [4]. LPG - The LPG price is rising. The refinery storage ratio has increased, and the port inventory has decreased slightly. The upstream operating rate has increased, while the downstream PDH operating rate has decreased significantly [6]. PVC and Caustic Soda - The caustic soda futures are oscillating weakly. The supply - demand imbalance persists, with high operating loads and high inventory. It is expected to oscillate weakly, and attention should be paid to the procurement volume of major downstream industries and the price fluctuations of liquid caustic soda. The PVC futures are oscillating weakly. The supply - demand situation has not improved, with high production and weak demand. The price is suppressed by the weak supply - demand situation but supported by costs. It is expected to oscillate widely in the range of 4820 - 5000 [8]. Urea - The urea futures are strengthening, and the spot price is firm. The supply is sufficient, and the industrial demand is general, while the agricultural demand is warming up. The pre - holiday order receiving is expected to be smooth. It is expected that the urea market will fluctuate slightly before the Spring Festival, and the main contract is expected to be in the range of 1760 - 1820 [9]. Natural Rubber - The supply of natural rubber is shrinking, and the cost support is strengthening. The demand is weakening as some enterprises are arranging holidays. The inventory in Qingdao is decreasing. The rubber price is expected to oscillate strongly in the short term, and long positions should be held [10]. Glass and Soda Ash - The soda ash futures are oscillating widely. The supply is strong, and the demand is weak. The inventory in the factory has increased slightly, and the social inventory has decreased. The price is mainly driven by market sentiment. The glass futures are also oscillating widely. The supply - demand situation is weak, and the price is supported by the cancellation of the "Three Red Lines" policy in the real estate market but is still affected by weak demand [13]. Polyester Industry Chain - For PX, the supply - demand situation in the first quarter is weaker than expected, but the price has strong support in the second quarter. It is expected to oscillate at a high level in the short term. For PTA, the supply - demand situation is weakening, and it is expected to oscillate at a high level. For ethylene glycol, the supply - demand situation is weak in the near term and strong in the long term. For short - fiber, the supply - demand situation is weak, and the price is expected to follow the raw materials. For polyester bottle - chips, the supply is expected to decrease, and the price and processing fee are expected to follow the cost [14]. Crude Oil - International oil prices are rising. Geopolitical factors, such as the tense situation in Iran and the US military deployment, and other factors like the US winter storm and the slow recovery of the Kazakh oil field, support the oil price in the short term. However, the overall supply - demand situation is weak, and there is pressure above $70 per barrel for Brent crude [15]. 3.
