Group 1: Investment Rating - No investment rating information is provided in the report. Group 2: Core Views - PTA market: Due to intensive PX maintenance, the internal - external price difference of PX has been significantly repaired. With the maintenance of domestic PTA plants, the PTA basis has strengthened significantly. The supply contraction of PTA and PX has led to a positive spread in the market. PTA is in a de - stocking cycle, and if polyester inventory remains strong, PTA inventory may continue to decline in June. Polyester factories are less likely to cut production [2]. - Ethylene glycol market: Trump's tariff policy has disrupted global trade, but the impact of ethane seems to have been minimized. The port inventory of ethylene glycol in East China remains at over 700,000 tons. The load recovery of coal - based ethylene glycol plants has pressured the market, but coal prices are rising. With the upcoming maintenance of mainstream ethylene glycol plants, it will enter a de - stocking phase [2].

Report Summary 1. Investment Rating The document does not mention the industry investment rating 2. Core Viewpoints - Terminal enterprises generally adopt a defensive strategy of low - inventory operation, and the probability of enterprises reducing production or stopping work during the May Day holiday is still high. The industry may face negative feedback in May, and the upward driving force of raw material varieties is not strong [1][6] - In the short term, PTA and short - fiber are likely to maintain a weak shock within a range. The finished product inventory is generally high, the raw material inventory is extremely low, and manufacturers' willingness to replenish inventory is very low [1] 3. Summary by Directory 3.1 Strategy Overview - The terminal is in the inventory accumulation stage. Some enterprises may increase the holiday time during the May Day holiday. The high - level operation of downstream enterprises may face negative feedback pressure [6] 3.2 Terminal Inventory Hoarding意愿不高, Negative Feedback May Still Have Room to Ferment - **Tariff Impact**: Export - oriented enterprises are actively responding to tariffs. Direct US orders are basically stagnant. Enterprises are looking for alternative markets such as South America, but the short - term effect is limited. Non - US orders, mainly from Southeast Asia, are relatively good. If tariffs do not change, enterprises may increase holidays and reduce production during the May Day holiday. Upstream chemical fiber factories may take further self - discipline measures [1][7][8] - **Start - up Situation**: Most enterprises are considering increasing holiday time during the May Day holiday depending on inventory. If inventory can be balanced, some enterprises may not take long holidays. Some enterprises are still hesitating due to existing orders. Some enterprises report that the accounts receivable period has become longer [1][9] - **Inventory and Replenishment**: Without significant changes in oil prices, PTA and short - fiber are unlikely to break through previous highs and may test resistance levels, maintaining a weak shock within a range. Finished product inventory is high, raw material inventory is extremely low, and manufacturers' willingness to replenish inventory is low. Some enterprises are hesitant to hoard goods due to low prices. Enterprises with sufficient funds may make small - scale purchases if sales improve or inventory pressure eases [1][9] 3.3 Enterprise Specific Situations and Demands - **Enterprise 1 (Fabric Export Factory)**: The enterprise has a 50 - 60% start - up rate. It is mainly export - oriented, with a low proportion of direct sales to the US. It is cautious about raw material inventory and focuses on sales. It exports mainly to Southeast Asian garment factories. It will not take holidays during the May Day holiday and will not hoard goods [11][12] - **Enterprise 2 (Curtain Export Manufacturer)**: The enterprise has a full start - up rate but a large inventory of about $15 million. It is actively looking for new processing locations and markets and plans to take more holidays during the May Day holiday. It is considering relocating to Southeast Asia or looking for contract manufacturers in Egypt [13][14] - **Enterprise 3 (Fabric Trader)**: The enterprise is facing a 245% top - level tariff on its export products. It can avoid taxes by under - reporting prices and is looking for contract manufacturers in Southeast Asia and Egypt. It has the idea of shifting to the domestic market but has not implemented it yet. It has low inventory and low inventory - building willingness [15] - **Enterprise 4 (Home Textile Exporter)**: The enterprise's US orders are basically stagnant, while Russian orders are good. It has learned that the start - up rate of local dyeing factories has decreased [16][19] - **Enterprise 5 (Warp - knitting Factory)**: The enterprise has a 60% start - up rate. It is cautious about stopping production due to output and tax payment requirements. It may take more holidays during the May Day holiday depending on inventory. It had inventory losses before and currently maintains a just - in - time inventory strategy. The finished product inventory is high, and the sales volume has decreased by half [20][21][24] - **Enterprise 6 (Circular Knitting Factory)**: The enterprise has a 90% start - up rate. It is less affected by tariffs, with 60% of its products for domestic sales. It has low inventory - building willingness and may consider replenishing inventory when prices are right. The downstream orders are few, and the profit is low [25][26] - **Enterprise 7 (Texturing Factory)**: One - third of the enterprise's texturing machines are shut down, and circular knitting machines are almost fully operational. It is hesitant to reduce production after the May Day holiday. It has high - cost raw material inventory and will adopt a strategy of short - term inventory replenishment [28][29] - **Enterprise 8 (Texturing Factory)**: The enterprise's texturing machines are fully operational after cleaning up inventory. It is uncertain whether to increase holidays after the May Day holiday. It has no intention to hoard inventory currently. The downstream orders are poor, and some customers will stop production during the May Day holiday [30]

Report Industry Investment Rating No relevant information provided. Core Views Polyolefin Industry - LL: In May, maintenance increases and imports decrease. If the exemption of ethane imports weakens the expectation of supply reduction, attention should be paid to the demand situation after May. Under the situation of weak supply and demand, the inventory pressure is still large, and there is a possibility of decline in the long - term pattern [4]. - PP: In the second quarter, the peak maintenance season eases the supply pressure slightly, but the output is still high. The demand has bottom support but is gradually weakening. The long - term pattern is weak, and there is a downward risk [4]. Styrene Industry - The market price of pure benzene continues to decline. The raw material trend is weak, and the downstream styrene futures are also weak. The supply of pure benzene has returned, and there is no sign of improvement. The styrene market is weakly volatile, and there is supply pressure in May. In the medium term, due to the impact of tariffs, there is price pressure on styrene. The strategy is to participate in high - altitude operations, with the upper resistance line at 7300 [11]. Polyester Industry - PX: The short - term trading may be stronger, and the strategy is to focus on expanding the low - level spread of PX - SC. - PTA: The supply and demand drive becomes stronger, and the price support is relatively strong. The strategy is to wait and see before the festival, and treat TA9 - 1 as a short - term positive spread and a medium - term reverse spread. - Ethylene glycol: It is expected to fluctuate in May. The strategy is that EGO9 is expected to fluctuate between 4050 - 4300. - Short - fiber: The rebound space is limited, and it will be mainly adjusted by shock before the festival. The strategy is similar to PTA for one - side trading, and pay attention to the opportunity to expand the processing fee of PFO6 below 900. - Bottle chips: The output is expected to be high, and the relative price follows the raw material fluctuations. The strategy is similar to PTA for one - side trading, and the main contract processing fee is expected to fluctuate between 350 - 550 yuan/ton [16]. PVC and Caustic Soda Industry - Caustic soda: The short - term supply and demand improve marginally, but the long - term expectation is weak. It is recommended to wait and see before the festival, and mainly go short in the medium - term for the 09 contract. - PVC: The start - up rate increases slightly, and the social inventory continues to decline seasonally. The demand is average, and there are problems in exports. The short - term operation should be cautious, and the medium - and long - term strategy is to participate in high - altitude operations [24]. Urea Industry - The main problem is the poor connection between supply and demand under the background of high supply. The supply pressure is increasing. The demand shows structural differentiation. The main contract 2509 may have a small rebound after the festival. It is recommended to wait and see before the festival, and take a short - selling strategy on rallies after the festival if there is a small rebound and no obvious improvement in the fundamentals. The option strategy is to buy and expand the spread in the short - term [30][31]. Crude Oil Industry - The overnight oil price was weakly running, pressured by macro - pressure and supply - side easing expectations. If the consumption end fails to replenish stocks in May, the downward channel of the market may further open. It is recommended to wait and see before the festival. The volatility ranges are given as [59, 69] for WTI, [62, 72] for Brent, and [460, 520] for SC. The option strategy is to focus on increasing volatility [49].

1. Report Industry Investment Rating No information provided in the report regarding the industry investment rating. 2. Core Viewpoints of the Report - The overall performance of energy - chemical commodities on April 30, 2025, showed price fluctuations. Most varieties are expected to remain volatile in the short term. For example, oil prices declined significantly due to factors such as increased US crude oil inventories and OPEC +'s potential acceleration of production increases. Other commodities like fuel oil, asphalt, and polyester also had their own price movements and influencing factors [1]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On April 30, WTI June contract closed down $1.63 to $60.42 per barrel, a 2.63% decline; Brent June contract closed down $1.61 to $64.25 per barrel, a 2.44% decline; SC2506 closed at 478.0 yuan per barrel, down 10.1 yuan per barrel, a 2.07% decline. API data showed that as of the week ending April 25, US API crude oil inventories increased by 3.8 million barrels, and Cushing crude oil inventories increased by 674,000 barrels. Analysts predicted a further increase of 500,000 barrels in US crude oil inventories, the fifth consecutive week of inventory growth. OPEC + members may propose to accelerate production increases in June, and Kazakhstan's crude oil exports in Q1 increased by 7% year - on - year, weakening the implementation of production - cut agreements. The market priced in the negative impact of accelerated production increases in advance, causing oil prices to fall. The market is expected to be volatile during the May Day holiday [1]. - **Fuel Oil**: On April 30, the main fuel oil contract FU2507 on the Shanghai Futures Exchange closed down 1.26% at 2,969 yuan per ton; the low - sulfur fuel oil contract LU2506 closed down 0.86% at 3,456 yuan per ton. It is expected that the reduction in East - West arbitrage arrivals in May will support the low - sulfur market in the short term. High - sulfur fuel oil is also supported by the expected improvement in Middle - East summer power - generation demand, but weak procurement demand in April and the arrival of Middle - East supplies at the end of April will put pressure on the market. It is recommended to mainly go long on crack spreads [1]. - **Asphalt**: On April 30, the main asphalt contract BU2506 on the Shanghai Futures Exchange closed up 0.53% at 3,430 yuan per ton. In terms of supply, refinery production in May is expected to increase month - on - month as processing profits recover, especially for local refineries. In terms of demand, the northern market demand is gradually being released, and pre - holiday stockpiling is good, but the terminal project start - up rate is still low, and the sales volume of modified plants has not increased significantly. The short - term absolute price of BU is expected to remain stable, and the previous crack - spread repair strategy can continue to be held, but attention should be paid to the pressure from increased supply [2]. - **Polyester**: On April 30, TA509 closed at 4,440 yuan per ton, down 0.89%; EG2509 closed at 4,187 yuan per ton, down 0.07%. PTA social inventories have been continuously decreasing, and planned maintenance in May is increasing, providing some price support. Ethylene glycol inventories have slightly increased, and due to factors such as postponed maintenance of oil - based units and concentrated arrivals of foreign vessels in April, the monthly de - stocking has narrowed. Downstream demand has some support in the short term, but there is a holiday expectation after the May Day holiday, so the price of ethylene glycol is expected to be volatile [2]. - **Rubber**: On April 30, the main natural rubber contract RU2509 closed down 95 yuan per ton to 14,635 yuan per ton; the main 20 - number rubber contract NR closed down 35 yuan per ton to 12,235 yuan per ton; the main butadiene rubber contract BR closed down 135 yuan per ton to 11,225 yuan per ton. As of the week ending April 27, the general trade inventory of natural rubber in Qingdao was 383,100 tons, an increase of 4,900 tons from the previous week, a 1.30% increase; the inventory in the Qingdao Free Trade Zone was 94,900 tons, an increase of 800 tons from the previous period, a 0.85% increase. The total inventory increased by 5,700 tons. Rubber supply is progressing well due to good weather, and downstream enterprises will have more holiday days during the May Day holiday than last year, so the fundamentals are weak, and the rubber price is expected to be weakly volatile [3][4]. - **Methanol**: On April 30, the spot price in Taicang was 2,437 yuan per ton, the price in Inner Mongolia's northern line was 2,155 yuan per ton, the CFR China price was between $259 - 263 per ton, and the CFR Southeast Asia price was between $337 - 342 per ton. In terms of supply, domestic supply will be stable in the future, and imports will gradually increase, with an expected increase in overall supply. In terms of demand, the maintenance of MTO units has been postponed, and traditional downstream demand changes are relatively limited. It is expected that the total demand in May will remain relatively stable. Overall, supply is expected to increase in May, demand will remain stable, inventory will no longer decrease, and the support for spot prices will weaken, with the basis expected to decline [4]. - **Polyolefins**: On April 30, the mainstream price of East - China drawn polypropylene was between 7,200 - 7,340 yuan per ton. In terms of profits, the gross profit of oil - based PP was 54.14 yuan per ton, the gross profit of coal - based PP production was 795.6 yuan per ton, the gross profit of methanol - based PP production was 936.67 yuan per ton, the gross profit of propane - dehydrogenated PP production was - 868.35 yuan per ton, and the gross profit of externally - purchased propylene - based PP production was - 99.67 yuan per ton. For polyethylene, the mainstream price of HDPE was 7,864 yuan per ton, the mainstream price of LDPE was 8,387 yuan per ton, and the mainstream price of LLDPE was 7,828 yuan per ton. The gross profit of oil - based polyethylene was - 125 yuan per ton, and the gross profit of coal - based polyethylene was 1,158 yuan per ton. May is the off - season for demand, and downstream enterprise start - up rates will slow down. The light - hydrocarbon production route is greatly affected by import tariffs, and production is expected to decline to some extent. Downstream inventory levels are not high, and rigid demand provides some price support, but due to the high supply level in the past five years, the price increase space is limited, and polyolefin futures are expected to remain narrowly volatile [5]. - **Polyvinyl Chloride (PVC)**: On April 30, the market price of PVC in East - China was moderately weak, with the price of calcium - carbide - based type 5 material between 4,720 - 4,860 yuan per ton and the price of ethylene - based material between 4,980 - 5,200 yuan per ton. The market price in North - China was weakly adjusted, with the price of calcium - carbide - based type 5 material between 4,740 - 4,820 yuan per ton and the price of ethylene - based material between 4,950 - 5,150 yuan per ton. The market price in South - China was moderately weak, with the price of calcium - carbide - based type 5 material between 4,830 - 4,950 yuan per ton and the price of ethylene - based material between 4,980 - 5,050 yuan per ton. Real - estate construction will enter the off - season, which will reduce the demand for PVC downstream pipes and profiles, and the start - up rate will decline slightly. Exports may also decline as India's BIS certification implementation time approaches. Overall, the PVC fundamentals will be loose in May, inventory pressure will increase, the spot price will be relatively weak, and although the main contract V2509 has peak - season expectations, its upward space is limited due to weak spot prices, and the price is expected to remain low and volatile, with the basis weakening [5][6]. 3.2 Daily Data Monitoring - The report provides the basis data of various energy - chemical varieties on April 30, 2025, including spot prices, futures prices, basis, basis rates, and the historical quantile of the latest basis rate, as well as the price changes of spot and futures prices and basis changes [7]. 3.3 Market News - API data showed that as of the week ending April 25, US API crude oil inventories increased by 3.8 million barrels, Cushing crude oil inventories increased by 674,000 barrels, gasoline inventories decreased by 3.1 million barrels, and distillate inventories decreased by 2.5 million barrels. Analysts predicted a further increase of 500,000 barrels in US crude oil inventories, the fifth consecutive week of inventory growth [9]. - OPEC + sources revealed that multiple members may propose to accelerate production increases in June. Kazakhstan's crude oil exports in Q1 increased by 7% year - on - year, weakening the implementation of production - cut agreements. Analysts believe that OPEC +'s proposal to increase production is a bad timing choice in the current weak market demand environment [9]. 3.4 Chart Analysis - **4.1 Main Contract Prices**: The report presents the closing - price charts of main contracts of various energy - chemical varieties from 2021 to 2025, including crude oil, fuel oil, asphalt, LPG, PTA, ethylene glycol, etc., to show the price trends of these varieties over the years [11]. - **4.2 Main Contract Basis**: The report shows the basis charts of main contracts of various energy - chemical varieties from 2021 to 2025, such as crude oil, fuel oil, asphalt, ethylene glycol, etc., to reflect the relationship between spot and futures prices [25]. - **4.3 Inter - period Contract Spreads**: The report provides the spread charts of different contracts of various energy - chemical varieties, such as fuel oil, asphalt, PTA, ethylene glycol, etc., including spreads between different contract months, to help analyze the price differences between different contracts [37]. - **4.4 Inter - variety Spreads**: The report presents the spread and ratio charts between different varieties of energy - chemical commodities, such as the spread between high - sulfur and low - sulfur fuel oil, the ratio of fuel oil to asphalt, the spread between ethylene glycol and PTA, etc., to analyze the price relationships between different varieties [55]. - **4.5 Production Profits**: The report shows the production - profit charts of some energy - chemical varieties, such as ethylene - based ethylene glycol cash flow, PP production profit, LLDPE production profit, etc., to reflect the profitability of these varieties [63]. 3.5 Team Member Introduction - **Zhong Meiyan**: The assistant director of the institute and the director of energy - chemical research.
