Report Industry Investment Rating - Not provided in the given content Core Viewpoints of the Report - Crude oil prices are expected to be volatile. Although short - term geopolitical disturbances and potential declines in US crude oil production have led to a short - term upward repair in market sentiment, the over - production of Kazakhstan and Iraq, and the expected increase in supply from OPEC+ may put pressure on prices [1]. - Fuel oil prices are expected to be volatile. The reduction in East - West arbitrage arrivals in May will support the low - sulfur market, and high - sulfur fuel oil is also supported by the expected improvement in Middle - East summer power generation demand. However, the low raw material procurement demand and the arrival of Middle - East supplies will also have an impact [2]. - Asphalt prices are expected to be volatile. With the repair of processing profits, supply is expected to increase. The expected acceleration of special bond issuance and the start of terminal projects with the warming weather will support demand, but attention should be paid to the pressure brought by the increase in supply [2]. - Polyester prices are expected to be volatile and weak. The decline in the prices of PX, PTA, and EG, the weak sales of polyester yarns, and the maintenance of some devices all indicate a weak market [2][4]. - Rubber prices are expected to be volatile and weak. Although Thailand's proposal to reduce import tariffs and the postponement of the rubber tapping season may support the market, the high raw material prices may lead to high tapping enthusiasm, and the weak terminal demand will still put pressure on prices [4][5]. - Methanol prices are expected to be volatile and weak. The supply is expected to increase, while the demand will remain relatively stable in May, leading to a loosening of spot price support [6]. - Polyolefin prices are expected to be volatile and weak. Although the supply is expected to decline due to refinery maintenance, the demand will enter the off - season, and the inventory decline will slow down [6]. - PVC prices are expected to be in low - level volatility. The real - estate construction off - season will reduce the demand for PVC downstream products, and the approaching implementation of the Indian BIS certification may lead to a decline in exports [7]. Summary by Relevant Catalogs Research Views - **Crude Oil**: On Tuesday, WTI June contract closed at $59.09/barrel, up $1.96 or 3.43%; Brent July contract closed at $62.15/barrel, up $1.92 or 3.19%; SC2506 closed at 465.9 yuan/barrel, up 8.1 yuan or 1.77%. Kazakhstan and Iraq have over - produced. The US API crude oil inventory decreased by 4.49 million barrels, and the EIA predicts that the US crude oil daily output in 2025 will be 13.42 million barrels, about 100,000 barrels less than last month's forecast [1]. - **Fuel Oil**: On Monday, FU2507 closed at 2,862 yuan/ton, up 1.13%; LU2506 closed at 3,405 yuan/ton, up 1.73%. The reduction in East - West arbitrage arrivals in May will support the low - sulfur market, and high - sulfur fuel oil is supported by the expected improvement in Middle - East summer power generation demand [2]. - **Asphalt**: On Monday, BU2506 closed at 3,424 yuan/ton, up 2.42%. With the repair of processing profits, supply is expected to increase. The expected acceleration of special bond issuance and the start of terminal projects will support demand [2]. - **Polyester**: TA509 closed at 4,362 yuan/ton, down 1.62%; EG2509 closed at 4,130 yuan/ton, down 0.6%. The sales of polyester yarns in Zhejiang and Jiangsu are weak, and some devices are under maintenance [2][4]. - **Rubber**: On Tuesday, RU2509 closed at 14,815 yuan/ton, up 260 yuan/ton; NR closed at 12,555 yuan/ton, up 270 yuan/ton. Thailand proposes to reduce import tariffs, and the rubber tapping season is postponed, but the terminal demand is weak [4][5]. - **Methanol**: On Tuesday, the spot price in Taicang was 2,420 yuan/ton. The supply is expected to increase, and the demand will remain relatively stable in May [6]. - **Polyolefins**: On Tuesday, the mainstream price of PP in East China was 7,150 - 7,300 yuan/ton. The supply is expected to decline due to refinery maintenance, but the demand will enter the off - season [6]. - **PVC**: On Tuesday, the price in the East - China PVC market decreased. The real - estate construction off - season will reduce the demand for PVC downstream products, and the inventory pressure will increase [6][7].

Research View - The research view on various agricultural products is mostly "sideways." Corn is in a sideways state, with long positions shifting to the July and September contracts. The spot market continues to show a strong performance driven by the futures. Northeast corn prices are rising, with a general increase of 10 - 20 yuan/ton, and traders' enthusiasm for shipping is average. In North China, corn prices are also running strongly. Technically, the July contract has broken through the previous high [1]. - Soybean meal is also in a sideways state. CBOT soybeans closed lower on Tuesday due to trade - related tensions and farmers' eagerness to plant soybeans. In the domestic market, the futures have raised the margin, and the market is mainly sideways. The spot supply of soybean meal is still tight, but it is expected to improve in May [1]. - Fats and oils are in a sideways state. BMD palm oil fell on Tuesday due to the strengthening of the Malaysian ringgit and the weakness of competing vegetable oils. Domestically, palm oil led the decline with reduced positions, and the oils market was weakly sideways. The increase in domestic ship purchases has pressured the spot and futures prices [1]. - Eggs are in a sideways state. On Tuesday, egg futures fluctuated. The spot price has been weak recently, but the May Day holiday has a certain boosting effect on terminal demand. After the plum - rain season, the egg price is likely to decline [1]. - Pigs are in a sideways state. On Tuesday, the September contract of live pigs fluctuated downward. Although the May Day holiday has increased the slaughtering enterprises' stocking demand, the impact on the pig price is limited. The market generally believes that the second - fattened pigs will be slaughtered more actively around May [2]. Market Information - The USDA announced that private exporters reported the sale of 110,000 tons of soybeans to unknown destinations and 120,000 tons of corn to Spain, all for delivery in the 2024/2025 marketing year [3]. - The Ministry of Agriculture and Rural Affairs will implement a hog production capacity regulation plan, aiming to reduce the proportion of grain in the feed consumed by the national aquaculture industry to about 60% and the proportion of soybean meal to about 10% by 2030 [3]. - As of the end of the 17th week of 2025, the domestic soybean meal inventory was 97,000 tons, a decrease of 57,000 tons from the previous week, a week - on - week decline of 37.00%. The coastal inventory was 84,000 tons, a decrease of 40,000 tons from the previous week, a week - on - week decline of 31.90% [4]. Variety Spreads Contract Spreads - The report presents the 9 - 1 spreads of various agricultural products, including corn, corn starch, soybeans, soybean meal, soybean oil, palm oil, eggs, and live pigs [6][7][9][13]. Contract Basis - The report shows the basis of various agricultural products, such as corn, corn starch, soybeans, soybean meal, soybean oil, palm oil, eggs, and live pigs [15][19][21][25]. Research Team Members - The agricultural product research team members include Wang Na, the director of the agricultural product research at Everbright Futures Research Institute; Hou Xueling, an analyst of beans at Everbright Futures; and Kong Hailan, a researcher of eggs and live pigs at Everbright Futures Research Institute [29]

Research Ratings for the Industry No information about the industry investment rating is provided in the report. Core Views of the Report - **Steel**: The rebar futures market declined yesterday. Spot prices also dropped, and trading volume decreased. Although the current supply - demand situation of rebar has improved, the impact of tariff policies on steel exports will gradually emerge, and the decline in cold - rolled demand may spread to hot - rolled products. There are also rumors about crude steel production cuts, which affect market sentiment. It is expected that the rebar futures market will remain in a low - level consolidation in the short term [1]. - **Iron Ore**: The price of the main iron ore futures contract declined yesterday. Supply has increased significantly, while demand, represented by hot metal production, has also risen. With the increase in port and steel mill inventories, and under the influence of long - and short - term factors, the iron ore futures price is expected to fluctuate and consolidate. Attention should be paid to information related to crude steel production cuts [1]. - **Coking Coal**: The coking coal futures market declined yesterday. The domestic supply is stable, and downstream inventory preparation for the May Day holiday has been completed. Traders are mostly on the sidelines, and spot purchases are scarce. Although the operating enthusiasm of coking enterprises has slightly increased, their coking coal inventory is sufficient. It is expected that the coking coal futures market will fluctuate and consolidate in the short term, and more support policies may be implemented in the second quarter [1]. - **Coke**: The coke futures market declined yesterday. The production of coking enterprises in the main production areas is normal, and the supply is relatively loose. The steel billet price has dropped, which has put pressure on raw material prices. Although steel mills have a good demand for coke, their profit margins are limited, so they are cautious about coke prices. It is expected that the coke futures market will fluctuate and consolidate in the short term, and more policy support may be implemented in the second quarter [1]. - **Silicon Manganese**: The silicon manganese futures price weakened in a fluctuating manner on Tuesday. The supply is still relatively high year - on - year, and the terminal demand is weak. The cost of manganese ore has remained stable recently. It is expected that the silicon manganese futures price will be weak and fluctuate in the short term [1][3]. - **Silicon Iron**: The silicon iron futures price weakened in a fluctuating manner on Tuesday. The production profit is still in the red, and the production decline has narrowed. The downstream steel procurement price is falling, and the demand support is limited. The cost is relatively stable. It is expected that the silicon iron futures price will fluctuate weakly in the short term [3]. Summary by Relevant Catalogs 1. Research Views - **Steel**: The closing price of the rebar 2510 contract was 3100 yuan/ton, a decrease of 29 yuan/ton or 0.93% from the previous trading day, with a reduction of 15,300 lots in positions.

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.

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.

1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - For stock indices, the current market focus has shifted from overseas to domestic demand. The Politburo meeting in April did not introduce significantly unexpected policies, and fiscal stimulus to boost domestic demand remains the main approach. In Q1 2025, China's general public - budget revenue decreased by 1.1% year - on - year, while expenditure increased by 4.2% year - on - year, with the issuance progress of ordinary national bonds reaching 30%, significantly ahead of schedule. The cumulative year - on - year revenue growth of industrial enterprises above designated size in March was 3.4%, consistent with previously released GDP and PPI data. Attention should be paid to whether the year - on - year revenue growth rate in A - share listed companies' financial reports matches these data to verify the economic recovery in Q1. The US tariff policy aims to reshape the global trade pattern through negotiations, which may affect China's exports to the EU, Japan, and South Korea and have a long - term impact on the A - share market. In the future, China's economic development will focus more on the domestic cycle, making the logic of central fiscal promotion of consumption more reasonable. Consumption and dividend themes may be relatively dominant for a long time this year, and for technology themes, sub - sectors such as domestic substitution and high - capital expenditure can be focused on. The view on the stock index is "volatile" [1]. - For national bonds, on the day of the report, the 30 - year main contract of national bond futures rose 0.69%, the 10 - year main contract rose 0.23%, the 5 - year main contract fell 0.13%, and the 2 - year main contract rose 0.01%. The central bank conducted 340.5 billion yuan of 7 - day reverse repurchase operations, with 220.5 billion yuan of reverse repurchases maturing, resulting in a net injection of 120 billion yuan. The money market was balanced, with the DR001 rate falling 5bp to 1.54% and the DR007 rate rising 3bp to 1.78%. The bond market in April first rose and then fell. At the beginning of the month, the market's risk - aversion sentiment increased under the influence of tariffs, and the yields of national bonds of all maturities declined rapidly by about 15BP. After the risk - aversion sentiment subsided, the bond market entered a sideways consolidation phase. In the short term, the market has fully priced in positive factors, economic and financial data have generally exceeded market expectations, and there is little need for an immediate interest - rate cut. Without an interest - rate cut, the bond market lacks the impetus to continue strengthening and will continue its current sideways and volatile trend. The view on national bonds is "volatile" [1][2] 3.
