1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints - This week, the cracking spread of Singapore 380cst high - sulfur fuel oil fluctuated, the near - month spread oscillated, the basis strengthened, the EW spread fluctuated at a high level, and the fluctuation of the near - month spread of domestic and foreign FU intensified due to delivery factors. The low - sulfur cracking spread weakened rapidly, the monthly spread weakened at an accelerated pace, the domestic and foreign spread of LU was compressed to $6 - 7 per ton, and the MF0.5 basis oscillated [3]. - Fundamentally, Singapore's residue decreased by 871,000 barrels, floating storage was slightly destocked, ARA residue inventory increased significantly, and EIA residue continued to accumulate. The high - sulfur peak season in the Middle East has passed. Due to the reshaping of logistics, the demand for high - sulfur marine fuel in Singapore provides support, and the EW spread has completed its repair. The domestic high - sulfur spread has risen again due to the impact of the delivery warehouse, and the short - term domestic and foreign spread has been repaired. This week, LU declined at an accelerated pace, and the basis of the external MF0.5 was weakly operating. Due to the support of the gasoline and diesel cracking spreads in Europe and the United States, the opportunity for the low - sulfur to high - sulfur spread to widen in the fourth quarter can be noted [4]. 3.

Report Industry Investment Rating - Not provided Core Viewpoints - This week, the high-sulfur cracking of Singapore 380cst fluctuated, the near-month spread fluctuated, the basis strengthened, the EW spread fluctuated at a high level, and the internal and external spreads of FU near-month were more volatile due to delivery factors. The low-sulfur cracking weakened rapidly, the spread accelerated to weaken, the internal and external spread of LU was compressed to $6-7 per ton, and the MF0.5 basis fluctuated. From a fundamental perspective, Singapore's residue decreased by 871,000 barrels, floating storage decreased slightly, ARA residue inventory increased significantly, and EIA residue continued to accumulate.

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst fluctuated strongly, the near - month spread strengthened slightly, the basis rebounded, and the EW spread continued to rebound. Affected by the impact of US sanctions on the delivery warehouse, FU10 rose sharply and then fell. The low - sulfur cracking weakened, the spread fluctuated, the LU internal - external spread fluctuated around $10, and the MF0.5 basis began to rebound [3][4]. - Fundamentally, Singapore's residue inventory increased, floating storage decreased, ARA's residue inventory remained flat, floating storage inventory increased significantly, and EIA residue began to accumulate. The global supply - demand of high - sulfur fuel oil weakened. Due to the reshaping of logistics, the demand for high - sulfur marine fuel in Singapore provided support, and the EW spread was still being repaired. The domestic high - sulfur spot was still in excess, and over - heated sentiment should be vigilant. The new round of sanctions had a large potential impact on the domestic heavy crude oil supply, providing some support for the Asian fuel oil valuation [4]. - This week, LU maintained a volatile trend, and the external MF0.5 basis began to rebound. Opportunities for the spread between low - sulfur and high - sulfur fuel oil to widen in the fourth quarter could be focused on [4]. 3.

Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst oscillated strongly, the near - month spread strengthened slightly, the basis rebounded, and the EW spread continued to rebound. Affected by the impact of US sanctions on delivery warehouses, FU10 soared and then declined. The low - sulfur cracking weakened, the spread oscillated, the LU internal - external spread fluctuated around 10 US dollars, and the MF0.5 basis began to rebound [4]. - Fundamentally, Singapore's residue inventory increased, floating storage decreased, ARA's residue inventory remained flat, floating storage inventory increased significantly, and EIA's residue began to accumulate. The global supply - demand of high - sulfur fuel oil weakened. Due to the reshaping of logistics, the demand for high - sulfur marine fuel in Singapore provided support, the EW spread was still being repaired, and the domestic high - sulfur spot was still in excess. Be vigilant against over - heating sentiment. The new round of sanctions has a large potential impact on the supply of heavy crude oil in China, providing some support for the valuation of Asian fuel oil. This week, LU maintained an oscillation, the external MF0.5 basis began to rebound, and the opportunity for the low - sulfur to high - sulfur spread to widen in the fourth quarter can be noted [5]. 3.

Report Summary 1. Report Industry Investment Rating - The provided content does not mention the industry investment rating. 2. Core Viewpoints of the Report - This week, the high - sulfur cracking of Singapore 380cst weakened, the near - month spread weakened (9 - 10 at 0.75 USD/ton, 10 - 11 at 3.25 USD/ton), the basis rebounded, and the EW spread continued to rebound. Affected by the new round of US sanctions on Iran (covering Dongjiakou and Yangshan Shengang), the near - month internal - external spread of FU fluctuated greatly, and the 09 contract once returned above par. [5][6] - The low - sulfur cracking weakened, the spread oscillated (9 - 10 at 2 USD/ton, 10 - 11 at 2.75 USD/ton), and the internal - external spread of LU strengthened slightly to 10 USD. [6] - Fundamentally, Singapore's land - based residue inventory continued to decline, floating storage inventory decreased significantly, and low - sulfur floating storage increased. The high - sulfur bunker volume in Singapore in July increased by 15% month - on - month and 10% year - on - year. [6] - The land - based inventory in Fujairah, Middle East decreased significantly, and floating storage decreased significantly. This week, Saudi Arabia's shipments decreased month - on - month, and UAE's shipments oscillated. [6] - US residue inventory increased slightly but remained at the lowest level in the same period of history, ARA ports decreased slightly, and floating storage increased slightly. [6] - The global supply - demand of high - sulfur fuel oil weakened. Due to the reshaping of logistics, the demand for high - sulfur marine fuel in Singapore provided support, and the EW spread was still recovering. There was still a large amount of FU delivery cargo, and attention should be paid to subsequent delivery changes. [6] - The new round of sanctions had a large potential impact on domestic heavy crude oil, providing a certain support for the valuation of Asian fuel oil. This week, LU remained weak, the basis of external MF0.5 oscillated at a low level, and the internal - external spread of LU oscillated. In the short term, opportunities for the expansion of high - sulfur 380 EW could still be concerned. [6] 3.
