1. Report Industry Investment Rating No information about the industry investment rating is provided in the report. 2. Core Viewpoints of the Report - The geopolitical situation in the Middle East is tense, with Trump warning Iran and the Houthi rebels launching missile attacks on Israel, which may lead to further escalation of the conflict and push up oil prices. The oil price is expected to fluctuate, and the overall center of gravity is moving upward [1]. - High - and low - sulfur fuel oils are supported by the cost of crude oil, and the supply is actually tightening. They are expected to maintain high - level operation, but the risk of a short - term sharp decline in oil prices after the end of the conflict should be noted [2]. - The demand for asphalt is gradually recovering, and the price is expected to be strong. However, the risk of a short - term sharp decline in oil prices after the end of the conflict should be noted, and its price volatility is expected to be smaller than that of other oil products [2]. - The polyester industry chain follows the cost - end fluctuations. The PX has many overhauls, the PTA operating load is at a high level, and the coal - based and oil - based production of ethylene glycol is differentiated. The downstream polyester yarn sales are sluggish [3]. - The natural rubber inventory is slightly increasing, and the butadiene rubber is oscillating strongly. The cash trends of natural rubber and butadiene are differentiated [5]. - The methanol inventory is starting to decline, but the supply recovery of Iranian plants may suppress price increases, and the market is prone to large fluctuations [5]. - The polyolefin market is de - stocking, but the short - term geopolitical risk pushes up the cost, which may hinder the growth of subsequent demand [6]. - The PVC export will supplement the domestic demand to a certain extent, and the short - selling power has not weakened. Attention should be paid to the fulfillment of export orders and the Middle East situation [6]. 3. Summary by Directory 3.1 Research Views - Crude Oil: On Monday, the WTI May contract closed up $3.24 to $102.88 per barrel, a 3.25% increase; the Brent May contract closed up $0.21 to $112.78 per barrel, a 0.19% increase; the SC2605 closed at 759.9 yuan per barrel, down 3.1 yuan per barrel, a 0.41% decrease. Geopolitical tensions may further push up oil prices, and the oil price is expected to oscillate [1]. - Fuel Oil: The main fuel oil contract FU2605 rose 4.05% to 4,619 yuan per ton, and the low - sulfur fuel oil contract LU2605 rose 3.44% to 5,285 yuan per ton. Affected by factors such as the rise in diesel cracking and freight, the supply is tightening, and it is expected to maintain high - level operation [2]. - Asphalt: The main asphalt contract BU2606 rose 0.02% to 4,513 yuan per ton. The demand is gradually recovering, and the price is expected to be strong [2]. - Polyester: The TA605 closed at 6,768 yuan per ton, down 1.57%; the EG2605 closed at 5,359 yuan per ton, up 1.52%. The industry chain is affected by the cost and device changes, and the market is waiting for the development of the situation [3]. - Rubber: The main natural rubber contract RU2605 rose 30 yuan per ton to 16,540 yuan per ton, and the NR main contract rose 110 yuan per ton to 13,845 yuan per ton. The natural rubber inventory is slightly increasing, and the butadiene rubber is oscillating strongly [5]. - Methanol: The inventory is starting to decline, but the supply recovery of Iranian plants may suppress price increases, and the market is prone to large fluctuations [5]. - Polyolefins: The upstream device overhauls and production cuts are more, and the demand is gradually released in spring. However, the short - term geopolitical risk pushes up the cost, which may hinder the growth of subsequent demand [6]. - Polyvinyl Chloride (PVC): The PVC export will supplement the domestic demand to a certain extent, and the short - selling power has not weakened. Attention should be paid to the fulfillment of export orders and the Middle East situation [6]. 3.2 Daily Data Monitoring - A table shows the basis data of various energy - chemical products on March 30, 2026, including spot prices, futures prices, basis, basis rates, and their changes, as well as the quantile of the latest basis rate in historical data [7]. 3.3 Market News - Trump warned Iran that unless the Strait of Hormuz is reopened, the US will destroy its oil wells, power plants, and Kharg Island. He also said that the response to Iran's attack on an Israeli refinery "will come soon" [9]. - US Treasury Secretary Scott Bessent said that as more ships pass through the Strait of Hormuz, the global oil market supply is sufficient, and the US will regain control of the Strait of Hormuz over time [9]. 3.4 Chart Analysis - 4.1 Main Contract Prices: There are multiple charts showing the closing prices of main contracts of various energy - chemical products from 2022 to 2026, including crude oil, fuel oil, low - sulfur fuel oil, asphalt, LPG, PTA, ethylene glycol, etc. [11][14][17][20][23][27][28] - 4.2 Main Contract Basis: There are charts showing the basis of main contracts of various energy - chemical products, such as crude oil, fuel oil, low - sulfur fuel oil, asphalt, ethylene glycol, etc. [29][30][33][35] - 4.3 Inter - period Contract Spreads: There are charts showing the spreads between different contracts of various energy - chemical products, such as fuel oil, PTA, ethylene glycol, PP, LLDPE, natural rubber, etc. [38][40][44][47][48][51] - 4.4 Inter - variety Spreads: There are charts showing the spreads and ratios between different varieties of energy - chemical products, such as crude oil internal and external spreads, fuel oil high - low sulfur spreads, fuel oil/asphalt ratio, etc. [54][56][57][59] - 4.5 Production Profits: There are charts showing the production profits of various energy - chemical products, such as LLDPE, PP, PTA processing fees, and ethylene - based ethylene glycol cash flow [61][63]
