Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Report Core View - This week, the high - sulfur cracking of Singapore 380cst fluctuated at a high level, the monthly spread of nearby months weakened, the basis oscillated at a low level, the EW spread weakened rapidly, the high - sulfur in the ARA region strengthened, and the FU internal - external spread oscillated between 8 - 10 US dollars. The low - sulfur cracking rebounded slightly but was at a historical low compared to the same period, the monthly spread was weakly sorted, the LU internal - external spread dropped to 7 - 9 US dollars, and the MF0.5 basis weakened. From the fundamental perspective, Singapore's residue oil inventory decreased (compared to a high level), floating storage decreased significantly, ARA residue oil inventory decreased at a historical low for the same period, EIA residue oil inventory slightly increased at a low level, Fujeirah slightly increased inventory (compared to a low level), and the Middle - East high - sulfur floating storage decreased significantly this week. Recently, the Singapore high - sulfur spot market has weakened, and the cracking is supported by raw material procurement, with limited short - term downward space. It is expected that the 380 cracking will maintain an oscillating pattern, and the FU internal - external spread should be viewed within a range. 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 weakened again. In the fourth quarter, the LU internal - external spread can be expanded on dips, and attention should be paid to the quota usage [3][4]. 3.

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst oscillated, the near - month spread oscillated, the basis strengthened slightly, the EW spread rebounded again and fluctuated widely recently, and the domestic and foreign near - months of FU oscillated. The low - sulfur cracking rebounded slightly but was at a historically low level, the monthly spread was weakly sorted, the domestic and foreign prices of LU rebounded slightly to $8 - 9 per ton, and the MF0.5 basis oscillated [5]. - Fundamentally, Singapore's residue decreased, floating storage oscillated, ARA residue inventory decreased slightly, EIA residue decreased slightly, Fujairah inventory decreased, and high - sulfur floating storage in the Middle East increased significantly. The high - sulfur peak season in the Middle East has passed. Supported by logistics reshaping and Singapore's high - sulfur marine fuel demand, the EW spread has been repaired. Recently, refinery feedstock purchases support the 380 cracking level, with limited short - term downside space. It is expected that the 380 cracking will maintain an oscillating pattern, and domestic FU should be considered with a short - term domestic and foreign oscillating and bullish mindset. 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 oscillated at a low level. In the fourth quarter, the domestic and foreign spreads of LU can be widened on dips, and attention should be paid to quota usage [6]. 3.

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 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. The external MF0.5 basis started to rebound, and the opportunity for the low - sulfur to high - sulfur spread to widen in the fourth quarter could be noted [4][10] Data Summary Rotterdam Fuel Oil Data | Type | 2025/08/29 | 2025/09/04 | Change | | --- | --- | --- | --- | | Rotterdam 3.5% HSF O Swap M1 | 389.06 | 377.63 | -0.64 | | Rotterdam 0.5% VLS FO Swap M1 | 456.37 | 441.32 | -4.96 | | Rotterdam HSFO - Brent M1 | -6.14 | -7.05 | 0.41 | | Rotterdam 10ppm Gasoil Swap M1 | 654.16 | 665.68 | -7.81 | | Rotterdam VLSFO - Gasoil M1 | -197.79 | -224.36 | 2.85 | | LGO - Brent M1 | 22.15 | 24.02 | -0.39 | | Rotterdam VLSFO - HSFO M1 | 67.31 | 63.69 | -4.32 | [2] Singapore Fuel Oil Data | Type | 2025/08/29 | 2025/09/04 | Change | | --- | --- | --- | --- | | Singapore 380cst M1 | 401.16 | 388.65 | -8.63 | | Singapore 180cst M1 | 416.16 | 398.86 | -10.92 | | Singapore VLSFO M1 | 485.77 | 468.34 | -16.91 | | Singapore GO M1 | 85.94 | 87.04 | -1.49 | | Singapore 380cst - Brent M1 | -4.48 | -5.32 | 0.53 | | Singapore VLSFO - Gasoil M1 | -150.19 | -175.76 | -5.89 | [2][9] Singapore Fuel Oil Spot Data | Type | 2025/08/29 | 2025/09/04 | Change | | --- | --- | --- | --- | | FOB 380cst | 399.85 | 387.09 | -9.17 | | FOB VLSFO | 488.05 | 474.28 | -11.56 | | 380 Basis | -1.10 | -1.00 | 0.45 | | High - sulfur Internal - external Spread | 2.4 | 6.0 | 0.0 | | Low - sulfur Internal - external Spread | 8.0 | 9.4 | -0.8 | [3] Domestic FU Data | Type | 2025/08/29 | 2025/09/04 | Change | | --- | --- | --- | --- | | FU 01 | 2812 | 2760 | -80 | | FU 05 | 2773 | 2721 | -76 | | FU 09 | 2735 | 2694 | -48 | | FU 01 - 05 | 39 | 39 | -4 | | FU 05 - 09 | 38 | 27 | -28 | | FU 09 - 01 | -77 | -66 | 32 | [3] Domestic LU Data | Type | 2025/08/29 | 2025/09/04 | Change | | --- | --- | --- | --- | | LU 01 | 3479 | 3395 | -97 | | LU 05 | 3435 | 3359 | -89 | | LU 09 | 3312 | 3341 | -100 | | LU 01 - 05 | 44 | 36 | -8 | | LU 05 - 09 | 123 | 18 | 11 | | LU 09 - 01 | -167 | -54 | -3 | [4]
