Report Summary 1) Report Industry Investment Rating No investment rating information is provided in the report. 2) Core Viewpoints - This week, the cracking spread of Singapore 380cst high - sulfur fuel oil oscillated, the near - month spread oscillated, the basis strengthened slightly, the EW spread rebounded again, and recently showed wide - range oscillations. The domestic FU showed an oscillating and slightly bullish trend in the short term. The low - sulfur cracking spread rebounded slightly but was at a historically low level compared to the same period. The month - spread was weakly sorted. The domestic and foreign prices of LU rebounded slightly to $8 - 9 per ton, and the MF0.5 basis oscillated [3][4]. - 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 the reshaping of logistics and the demand for high - sulfur marine fuel in Singapore, the EW spread has been repaired. Recently, refinery feedstock purchases have supported the 380 cracking level, with limited short - term downside space, and the 380 cracking spread is expected to maintain an oscillating pattern [4]. - This week, the LU market remained weak. The issuance of the third batch of export quotas was in line with expectations, and the MF0.5 basis of the outer market oscillated at a low level. In the fourth quarter, one can buy on dips to widen the domestic and foreign spreads of LU, and pay attention to the quota usage [4]. 3) Summary by Related Catalogs Rotterdam Fuel Oil Swap Data | Product | Initial Value (2025/09/18) | Final Value (2025/09/22) | Change | | --- | --- | --- | --- | | Rotterdam 3.5% HSF O Swap M1 | 383.35 | 386.97 | 5.78 | | Rotterdam 0.5% VLS FO Swap M1 | 434.21 | 427.29 | 3.12 | | Rotterdam HSFO - Brent M1 | - 6.64 | - 4.97 | 0.17 | | Rotterdam 10ppm Gasoil Swap M1 | 677.55 | 664.85 | 5.62 | | Rotterdam VLSFO - G O M1 | - 243.34 | - 237.56 | - 2.50 | | LGO - Brent M1 | 25.18 | 24.40 | - 0.91 | | Rotterdam VLSFO - HSFO M1 | 50.86 | 40.32 | - 2.66 | [1] Singapore Fuel Oil Swap Data | Product | Initial Value (2025/09/18) | Final Value (2025/09/24) | Change | | --- | --- | --- | --- | | Singapore 380cst M1 | 396.06 | 405.15 | 10.91 | | Singapore 180cst M1 | 407.26 | 414.65 | 12.15 | | Singapore VLSFO M1 | 472.28 | 468.56 | 5.45 | | Singapore GO M1 | 88.34 | 88.66 | 2.00 | | Singapore 380cst - Brent M1 | - 4.97 | - 3.17 | 0.57 | | Singapore VLSFO - G O M1 | - 181.44 | - 187.52 | - 9.35 | [1] Singapore Fuel Oil Spot Data | Product | Initial Value (2025/09/18) | Final Value (2025/09/24) | Change | | --- | --- | --- | --- | | FOB 380cst | 397.47 | 406.82 | 11.62 | | FOB VLSFO | 472.07 | 466.07 | 4.92 | | 380 Basis | 0.60 | 1.45 | 0.45 | | High - Sulfur Domestic - Foreign Spread | 7.5 | 6.9 | - 2.8 | | Low - Sulfur Domestic - Foreign Spread | 9.7 | 9.4 | - 0.5 | [2] Domestic FU Data | Product | Initial Value (2025/09/18) | Final Value (2025/09/24) | Change | | --- | --- | --- | --- | | FU 01 | 2798 | 2860 | 101 | | FU 05 | 2754 | 2808 | 90 | | FU 09 | 2698 | 2726 | 53 | | FU 01 - 05 | 44 | 52 | 11 | | FU 05 - 09 | 56 | 82 | 37 | | FU 09 - 01 | - 100 | - 134 | - 48 | [2] Domestic LU Data | Product | Initial Value (2025/09/18) | Final Value (2025/09/24) | Change | | --- | --- | --- | --- | | LU 01 | 3385 | 3367 | 42 | | LU 05 | 3368 | 3347 | 45 | | LU 09 | 3322 | 3319 | 33 | | LU 01 - 05 | 17 | 20 | - 3 | | LU 05 - 09 | 46 | 28 | 12 | | LU 09 - 01 | - 63 | - 48 | - 9 | [3]
