Report Information - Report Date: June 23, 2025 [2] - Report Team: Research Center Energy and Chemicals Team [2] Industry Investment Rating - Not provided Core Views - This week, high-sulfur cracking fluctuated, crude oil prices rose significantly, Iran accounted for a large proportion of high-sulfur supply, and it performed well in oil product profits. The 380-month spread fluctuated, the 8-9 spread was $7.5, the basis fluctuated, and there was a differentiation between near and far months of FU at home and abroad. The 07 contract dropped to around -$7 (it is expected that there will be a large amount of delivery goods), and the 09 contract fluctuated at $8. The 0.5 cracking in Singapore declined, and the month spread fluctuated [4]. - This week, land-based inventories in Singapore decreased, high-sulfur floating storage inventories increased, low-sulfur floating storage inventories increased, ARA inventories decreased, floating storage inventories fluctuated, and US inventories decreased. Saudi Arabia's shipments decreased month-on-month, and were moderately high compared to the same period. Russia's shipments were neutral. Iran and Iraq accounted for about 15%-20% of Singapore's high-sulfur imports, mainly affecting some bunkering and refinery feedstock in the Asia-Pacific region and cannot participate in physical delivery on the futures market. It is expected that Iran's shipments will decline in the future, mainly due to the impact of US sanctions. If the risk events in the Strait of Hormuz escalate, the impact will be greater. Recently, high-sulfur fuel oil is still in the peak power generation season, the overseas market is operating strongly, the near months of FU at home and abroad are under pressure, the valuation is low, and the game continues. Pay attention to the impact of supply disruptions in the far months. The domestic and overseas valuations of LU are high [4][5].

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - This week, the high - sulfur crack spread declined, the 380 - month spread declined, and the basis strengthened. The low - sulfur crack spread weakened in a volatile manner, the near - end month spread weakened slightly, and the basis weakened. [6] - Singapore's on - land inventory continued to accumulate, ARA ports continued to accumulate inventory, and US residual oil slightly reduced inventory. Recently, the low - sulfur valuation showed that there is room for downward correction in the crack spread and the inter - month spread after supply recovery. [6][11] - The high - sulfur crack spread has started to loosen, and the overseas market game remains strong. Affected by consumption tax deductions and tariff adjustments in China this year, the refinery feedstock demand for fuel oil has significantly declined. In the bunker fuel sector, global high - sulfur bunker fuel from January to March increased by 2% year - on - year, Singapore remained basically flat, and the total bunker fuel was weaker year - on - year. Attention should be paid to the impact of tariffs on global trade activities. [11] - Recently, Saudi Arabia's net imports have rebounded, and Egypt's purchases have continued. High - sulfur fuel oil is still in the peak season. Attention should be paid to the opportunity of the medium - term decline in the high - sulfur crack spread. With high domestic production scheduling, a short - selling approach should be maintained for the domestic - overseas spread of LU. [11] 3.

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]
