Report Industry Investment Rating No relevant content provided. Report's Core View - This week, the high - sulfur cracking of Singapore 380cst fluctuated, the near - month spread fluctuated, the basis strengthened slightly, the EW spread rebounded again, and recently showed wide - range fluctuations. The FU internal - external near - month also fluctuated. The low - sulfur cracking rebounded slightly but was at a historically low level year - on - year, the spread was weakly sorted, the LU internal - external price rebounded slightly to $8 - 9 per ton, and the MF0.5 basis fluctuated [3][4]. - From a fundamental perspective, Singapore's residual oil decreased, floating storage fluctuated, ARA residual oil inventory decreased slightly, EIA residual oil decreased slightly, Fujairah inventory decreased, and Middle - East high - sulfur floating storage increased significantly. The high - sulfur Middle - East peak season has passed. Supported by logistics reshaping and Singapore's high - sulfur marine fuel demand, the EW spread has completed its repair. Recently, refinery feedstock procurement has supported the 380 cracking level, with limited short - term downside space. It is expected that the 380 cracking will maintain a fluctuating pattern, and a short - term internal - external bullish view is taken on domestic FU [4]. - This week, the LU market was still weak. The issuance of the third batch of export quotas met expectations, and the external MF0.5 basis fluctuated at a low level. In the fourth quarter, the LU internal - external spread can be enlarged on dips, and attention should be paid to quota usage [4].

Report Overview - The report is a fuel oil morning report released by the energy and chemical team of the research center on September 5, 2025, covering fuel oil data from August 29 to September 4, 2025 [1] Report Industry Investment Rating - Not provided Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst strengthened oscillatingly, 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 rose sharply and then fell. The low - sulfur cracking weakened, the spread oscillated, and the LU internal - external spread fluctuated around 10 US dollars. The MF0.5 basis began to rebound. 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 logistics reshaping, 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. A new round of sanctions had 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.

Report Summary 1. Report Industry Investment Rating No information provided. 2. 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.
