1. Report Industry Investment Rating - No relevant content provided. 2. Core Viewpoints of the Report - The prices of PX, PTA, MEG, short - fiber, and bottle - chip futures have shown upward trends recently. The main reasons include increased gasoline demand leading to higher naphtha demand, multiple device overhauls in the industry, improved macro - atmosphere due to the mutual tariff reduction between China and the US, and changes in supply - demand relationships in different segments of the polyester industry chain. In the short term, these products are expected to fluctuate with a strong bias [6][7][9]. 3. Summary by Related Catalogs 3.1 Basic Data - **Futures Closing Prices**: From May 9th to May 12th, 2025, most futures contracts in the polyester industry chain showed price increases. For example, the 2506 contract of PX rose from 6626 to 6806, with an increase of 180 and a growth rate of 2.72%. The 2506 contract of PTA increased from 4684 to 4836, with an increase of 152 and a growth rate of 3.25% [5]. - **Spot Prices**: Spot prices also generally increased. For instance, the PTA spot price rose from 4301 to 4400, with a growth rate of 2.30%. The PF (1.4D) spot price increased from 6440 to 6525, with a growth rate of 1.32% [5]. - **Basis**: The basis of some products changed significantly. The PTA09 main - port basis increased from 149 to 175, with a growth rate of 17.45%. The MEG09 spot basis rose from 78 to 128, with a growth rate of 64.10% [5]. - **Monthly Spread**: There were also changes in monthly spreads. The TA9 - 1 monthly spread decreased from 72 to 71, with a decline rate of 5.56%, while the EG9 - 1 monthly spread increased from 3 to 23, with a growth rate of 666.67% [5]. - **Industrial Chain Price Differences and Profits**: Some price differences and profits in the industrial chain changed. The PTA - PX (09 futures contract) price difference increased from 343 to 352, with a growth rate of 2.56%. The PF06 contract processing fee increased from 881 to 1220, with a growth rate of 38.49% [5]. 3.2 Product Analysis - **PX**: The PX futures price continued to rise. Due to increased gasoline demand, the demand for naphtha for gasoline blending increased. Multiple PX device overhauls were planned, and the market atmosphere improved. The PX - naphtha price difference recovered, and PX valuation was upward - repaired. In the short term, PX is expected to fluctuate with a strong bias [6]. - **PTA**: The PTA futures price continued to rise, and the basis strengthened. Multiple PTA device overhauls in May led to a significant decline in the operating rate and an upward repair of processing fees. After the May - Day holiday, the polyester operating rate continued to increase, expanding the PTA supply - demand gap. In the short term, PTA is expected to fluctuate with a strong bias [7]. - **MEG**: The MEG futures price increased. The port inventory decreased, and the domestic operating rate recovered due to the restart of multiple synthetic - gas - based MEG overhaul devices. The supply increased overall, and the inventory pressure was not large. The polyester operating rate remained high, and the supply - demand relationship was in a tight - balance pattern. In the short term, MEG is expected to fluctuate with a strong bias [8][9]. - **Short - fiber**: The prices of polyester raw material futures continued to strengthen, and short - fiber factory quotes increased. Downstream stocking sentiment improved, and the average sales rate reached 132%. After the holiday, both supply and demand increased, and the inventory changed little. Short - fiber prices followed the trend of raw materials [10]. - **Bottle - chip**: The prices of polyester raw material futures continued to strengthen, and the bottle - chip futures price increased. A bottle - chip device restarted, and the supply was stable. Although the downstream market atmosphere weakened, the export efficiency was good, and the overall demand was still supported. The current processing fee valuation was low, and the price followed the trend of raw materials [11].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - Demand has improved slightly on a month - on - month basis, supply remains at a low level, and the inventory accumulation speed of the industry chain has slowed down since the second quarter. Low inventory supports the near - end spot price and benefits the long - term peak - season expectations. Due to the US pressure on Chinese refineries during the sanctions on Iran, concerns about overseas crude oil supply and domestic asphalt supply have increased. Coupled with positive signals from China - US trade negotiations, oil prices are strong in the short term, and asphalt prices have risen accordingly. In the medium and long term, with the expected continuous production increase of OPEC, the upward space for oil prices is limited. Currently, the supply - demand situation of asphalt is neutral, and the unilateral price is expected to fluctuate at a high level, while the asphalt/crude oil spread will remain high. The operating range of the BU2506 contract is expected to be between 3300 and 3500 [7]. Group 3: Summary According to Relevant Catalogs 1.

Report Summary 1. Report Industry Investment Rating No investment rating for the industry is provided in the report. 2. Core Viewpoints - The international soybean market has limited near - term pressure, with good US soybean export performance and reduced selling pressure in Brazil. However, the long - term supply is expected to be relatively loose due to high projected US soybean ending stocks and continued pressure in the South American market. - In the domestic market, the recent tight supply situation is gradually improving as the oil mill operating rate increases and soybean arrivals become clearer. - The macro - environment has a complex and limited impact on soybean meal, as China still imposes tariffs on US soybeans. - The soybean meal futures market is expected to face some pressure, while the rapeseed meal market may see weakening demand and limited supply - side benefits[5][6][7]. 3. Summary by Related Content Market Quotes - The US soybean futures market showed a strong trend due to improved macro - conditions after China - US talks. The domestic futures market was mainly in shock, with soybean meal outperforming rapeseed meal. - For soybean meal futures, the contract 0105 closed at 2955, down 6; contract 09 at 2919, down 1. For rapeseed meal futures, contract 01 closed at 2330, down 15; contract 05 at 2485, up 1; contract 09 at 2563, down 2. - The basis of soybean meal in Tianjin was 420, up 40; in Dongguan, it was 220, down 130; in Zhangjiagang, it was 200, up 10; in Rizhao, it was 190, up 30. The basis of rapeseed meal in Nantong was - 63, up 42; in Guangdong, it was - 113, down 8; in Guangxi, it was - 123, down 8. - The 5 - 9 spread of soybean meal was - 132, up 28; the 9 - 1 spread was - 36, up 5; the 1 - 5 spread was 168, down 33. The 5 - 9 spread of rapeseed meal was - 78, up 3; the 9 - 1 spread was 233, up 13; the 1 - 5 spread was - 155, down 16. - The spread between soybean meal and rapeseed meal was 852, down 18; between soybean meal and sunflower meal was 1039, down 111; between rapeseed meal and sunflower meal was 117, down 3[4]. Fundamental Analysis - International: As of the week ending May 1, US soybean export sales were 376,700 tons. The March crushing data was average, but overall demand was good. Brazil's soybean harvest progress as of May 3 was 97.7%, higher than last year and the five - year average. The long - term US soybean ending stocks are expected to remain high due to large export pressure on new crops, and the South American market will continue to face pressure. - Domestic: As of May 9, the actual soybean crushing volume of oil mills was 1.846 million tons, with an operating rate of 51.89%. Soybean inventory was 5.3491 million tons, up 602,700 tons (12.7%) from last week and 1.1634 million tons (27.79%) from last year. Soybean meal inventory was 101,200 tons, up 19,100 tons (23.26%) from last week but down 458,000 tons (81.9%) from last year. The rapeseed crushing volume of coastal oil mills was 159,500 tons, with an operating rate of 42.51%. Rapeseed inventory was 200,000 tons, down 68,000 tons from last week, and rapeseed meal inventory was 36,000 tons, up 21,500 tons from last week[5][6]. Macro - environment The postponement and reduction of tariffs by China and the US have complex and limited impacts on soybean meal, as China still imposes tariffs on US soybeans[6]. Logic Analysis - Soybean meal: With the increase in the operating rate of domestic oil mills, the supply shortage is alleviated. The upcoming monthly supply - demand report may be a focus, but the pricing center is still in South America, so the market may face pressure. - Rapeseed meal: The market's focus is on future supply. With the decline in soybean meal prices, rapeseed meal demand may weaken, and supply - side benefits may be limited. The inter - monthly spreads of both soybean meal and rapeseed meal are expected to be volatile[7]. Trading Strategies - Unilateral trading: Hold a wait - and - see attitude. - Arbitrage: Hold a wait - and - see attitude. - Options: Adopt a strategy of selling wide straddles[8]. Soybean Crushing Profit - For soybeans from Argentina, the May shipment had a crushing profit of 75.10; June shipment, 11.48; July shipment, - 76.77. - For soybeans from Brazil, the June shipment had a crushing profit of 102.52; July shipment, 82.62; August shipment, 15.34[9].
