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]

Report Industry Investment Rating - Not provided 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 rose sharply and then fell. The low-sulfur cracking weakened, the spread oscillated, the LU internal and external spread fluctuated around 10 US dollars, and the MF0.5 basis began to rebound [3]. - 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 and 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. The domestic high-sulfur spot was still in excess supply, so beware of overheating sentiment. The new round of sanctions has a large potential impact on the supply of heavy crude oil in China, which provides some support for the valuation of Asian fuel oil. This week, LU remained oscillating, and the basis of the external MF0.5 began to rebound. One can pay attention to the opportunity of the low-sulfur - high-sulfur spread widening in the fourth quarter [4].

Report Summary 1. Report Industry Investment Rating - No information provided in the document. 2. Core Viewpoints - 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 Shenggang), the near - month internal - external spread of FU fluctuated greatly, and the 09 contract once returned above par. 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 [2][3]. - Fundamentally, Singapore's land - based residue inventory continued to decline, floating storage inventory decreased significantly, and low - sulfur floating storage increased. In July, Singapore's high - sulfur bunker fueling volume increased by 15% month - on - month and 10% year - on - year. 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. US residue inventory increased slightly but remained at the lowest level in the same period in history, ARA ports decreased slightly, and floating storage increased slightly [3]. - 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. The delivery volume of FU was still relatively large, and subsequent delivery changes should be monitored. The new round of sanctions had a relatively 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 considered [3]. 3.

Report Summary 1) Report Industry Investment Rating - No investment rating information is provided in the report. 2) Core Viewpoints - The PG futures price fluctuated and strengthened, mainly due to the rebound of spot prices and the increase in import costs [1]. - The fundamentals show that port supply and demand both decreased, inventory remained basically flat, refinery product volume increased by 1.94%, and plant inventories decreased due to the recovery of demand in many places [1]. - The combustion off - season is gradually coming to an end as the temperature begins to drop. The supply of refineries in East China is expected to be limited, and the arrival of ships is expected to decrease. The demand is expected to improve, and the overall situation is expected to be stable [1]. 3) Summary by Related Content Price Data - From August 22 - 28, 2025, the prices of South China LPG, Shandong LPG, Shandong ether - after carbon four, and other products showed certain fluctuations.

Report Information - Report Date: August 28, 2025 [2] - Report Team: Research Center Energy and Chemicals Team [2] Industry Investment Rating - Not provided Core Views - This week, the high-sulfur cracking of Singapore 380cst weakened, and the near-month spread weakened. The low-sulfur cracking weakened, and the spread fluctuated. The high-sulfur global supply and demand weakened, but the EW spread was still being repaired. The new round of sanctions had a large potential impact on domestic heavy crude oil and provided some support for Asian fuel oil valuations. The LU remained weak this week, and short-term opportunities for the expansion of high-sulfur 380 EW could still be monitored.
