Group 1: Report Industry Investment Rating - No relevant content Group 2: Core Viewpoints of the Report - This week, the high - sulfur cracking was volatile. The 380 near - end ran strongly, the monthly spread strengthened again, and the basis was volatile. The low - sulfur cracking was volatile, the near - end monthly spread declined, and the basis was volatile. This week, there was a significant inventory build - up on land in Singapore, a slight inventory build - up at ARA ports, and a drawdown of residual oil in the US. Recently, the low - sulfur valuation has been realized, and there is room for repair in cracking and inter - monthly spreads after supply recovery. The high - sulfur cracking ran strongly, with profits higher than the historical average. This year, in China, affected by consumption tax deductions and tariff adjustments, the feedstock demand of fuel oil refineries has significantly declined. In terms of marine fuel, the global high - sulfur marine fuel from January to March increased by 2% year - on - year, and Singapore was basically flat. The total marine fuel was weaker year - on - year. Subsequently, the impact of tariffs on global trade activities should be monitored. Recently, Saudi Arabia's net imports have rebounded, and Egypt's purchases have continued. The high - sulfur near - end is strong. Opportunities for the decline of high - sulfur cracking in the medium and long term should be monitored [5][6] Group 3: Summary by Related Catalogs Rotterdam Fuel Oil Swap Data - From May 20th to May 26th, 2025, for Rotterdam's 3.5% HSFO swap M1, the price changed from 407.23 to 401.31, a decrease of 4.33; for Rotterdam's 0.5% VLSFO swap M1, it changed from 446.09 to 447.03, a decrease of 2.24; for Rotterdam's HSFO - Brent M1, it changed from - 0.27 to - 0.94, a decrease of 0.50; for Rotterdam's 10ppm Gasoil swap M1, it changed from 588.04 to 585.92, a decrease of 2.40; for Rotterdam's VLSFO - GO M1, it changed from - 141.95 to - 138.89, an increase of 0.16; for LGO - Brent M1, it changed from 15.90 to 16.20, a decrease of 0.30; for Rotterdam's VLSFO - HSFO M1, it changed from 38.86 to 45.72, an increase of 2.09 [3] Singapore Fuel Oil Swap and Spot Data - Swap data: From May 20th to May 26th, 2025, for Singapore's 380cst M1, the price changed from 431.93 to 424.98, a decrease of 1.56; for Singapore's 180cst M1, it changed from 438.43 to 431.23, a decrease of 1.68; for Singapore's VLSFO M1, it changed from 485.73 to 484.07, an increase of 4.57; for Singapore's GO M1, it changed from 79.88 to 79.00, an increase of 0.77; for Singapore's 380cst - Brent M1, it changed from 3.21 to 2.50, a decrease of 1.24; for Singapore's VLSFO - GO M1, it changed from - 105.38 to - 100.53, a decrease of 1.13 [3] - Spot data: From May 20th to May 26th, 2025, for Singapore's FOB 380cst, the price changed from 434.71 to 430.07, an increase of 1.27; for FOB VLSFO, it changed from 498.93 to 493.11, an increase of 3.07; the 380 basis changed from - 0.25 to 7.15, an increase of 5.65; the high - sulfur internal - external spread changed from 9.6 to 8.8, a decrease of 0.6; the low - sulfur internal - external spread changed from 12.2 to 13.1, a decrease of 1.2 [4] Domestic Fuel Oil Futures Data - FU data: From May 20th to May 26th, 2025, for FU 01, the price changed from 2722 to 2681, a decrease of 11; for FU 05, it changed from 2662 to 2627, a decrease of 11; for FU 09, it changed from 2874 to 2836, an increase of 3; FU 01 - 05 remained unchanged at 54; FU 05 - 09 changed from - 212 to - 209, a decrease of 14; FU 09 - 01 changed from 152 to 155, an increase of 14 [4] - LU data: From May 20th to May 26th, 2025, for LU 01, the price changed from 3390 to 3360, an increase of 2; for LU 05, it changed from 3314 to 3285, a decrease of 6; for LU 09, it changed from 3445 to 3431, an increase of 26; LU 01 - 05 changed from 76 to 75, an increase of 8; LU 05 - 09 changed from - 131 to - 146, a decrease of 32; LU 09 - 01 changed from 55 to 71, an increase of 24 [5]
