Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst fluctuated 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 the delivery warehouse, FU10 rose sharply and then fell. The low - sulfur cracking weakened, the spread fluctuated, the LU internal - external spread fluctuated at $10, and the MF0.5 basis began to rebound [3][4]. - Fundamentally, the residue inventory in Singapore increased, the floating storage decreased, the residue inventory in ARA remained flat, the floating storage inventory increased significantly, and the EIA residue began to accumulate. 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, the EW spread was still being repaired, and the domestic high - sulfur spot was still in excess. Be vigilant against over - heating sentiment [4]. - The new round of sanctions has a relatively large potential impact on the domestic heavy crude oil supply, which provides a certain support for the Asian fuel oil valuation. This week, LU maintained a volatile trend, and the MF0.5 basis of the external market began to rebound. The opportunity for the spread between low - sulfur and high - sulfur fuel oil to widen in the fourth quarter can be concerned [4]. 3.

Report Overview Investment Rating - No investment rating information is provided in the report. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst weakened, and the near - month spread weakened (9 - 10 at 0.75 USD/ton, 10 - 11 at 3.25 USD/ton). The LU maintained a weak trend, with the external MF0.5 basis oscillating at a low level and LU internal - external spread oscillating. The low - sulfur cracking weakened, and the spread oscillated (9 - 10 at 2 USD/ton, 10 - 11 at 2.75 USD/ton). The LU internal - external spread strengthened slightly to 10 USD. [5][6] - 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 bunkering 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. The US residue inventory increased slightly but remained at the lowest level in the same period of history, ARA ports decreased slightly, and floating storage increased slightly. [6] - 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 FU delivery volume was still relatively large, and attention should be paid to subsequent delivery changes. The new round of sanctions had a relatively large potential impact on domestic heavy crude oil, providing some support for Asian fuel oil valuation. In the short term, opportunities for the expansion of high - sulfur 380 EW could still be monitored.

Report Industry Investment Rating - Not provided Core Viewpoints - This week, the cracking spread of Singapore 380cst high-sulfur fuel oil rebounded, the near-month spread rebounded, and the EW spread continued to rebound. The 9 - 10 spread rebounded to $5.5/ton, the basis oscillated at a low level (-$5), and the internal - external spread of FU01 slightly strengthened to $2.5. The cracking spread of Singapore 0.5% low - sulfur fuel oil continued to weaken, the 9 - 10 spread slightly rebounded to $3.75/ton, and the internal - external spread of LU11 oscillated around $8. [3][4] - This week, Singapore's on - land inventory increased significantly, reaching the highest level in the same period of history. Floating storage increased on a month - on - month basis. Saudi Arabia's shipments were at a historical high in the same period, and the arrivals rebounded this week. UAE's shipments rebounded significantly on a month - on - month basis, and net exports increased significantly. The divergence between the East and the West in high - sulfur fuel oil continued, and the current price difference has triggered logistics changes. In the heavy - oil pattern, the cracking spread of Singapore 380cst is the weakest, and the premium of heavy crude oil is the strongest. It is expected that there will be a two - way regression in the future. [4] - This week, LU's weakening was realized, the spot price of the external MF0.5 slightly weakened, and the valuation was realized. Attention should be paid to the subsequent release of LU quotas. Attention should be paid to the opportunity of the widening of the 380 EW spread of high - sulfur fuel oil, and short - term short positions in LU should be exited.

Report Overview - The report is a Fuel Oil Morning Report from the Energy and Chemicals Team of the Research Center, dated July 25, 2025 [3] Report Core View - This week, the high - sulfur crack spread oscillated downward, the near - month spread declined, and EW continued to weaken. The 380 8 - 9 month spread weakened to $1.75, the basis weakened and then oscillated, the FU09 internal - external spread rebounded slightly, and the domestic market had a large amount of delivery goods, maintaining a loose pattern. The Singapore 0.5 crack spread declined slightly, the month spread weakened, and the 8 - 9 month spread oscillated around $4.5. The LU internal - external spread weakened slightly and then oscillated, with the 09 spread oscillating around $16. Singapore's on - land inventory increased significantly this week, the near - month was under pressure due to delivery, and Saudi shipments increased month - on - month. Recently, fuel oil exports from Iran and Iraq remained at a high level, Egypt's net imports reached a new high, and the high - sulfur supply - demand was still in the peak season, but the East - West and internal - external spreads had dropped rapidly. The external low - sulfur valuation was high, and the LU internal - external spread was at a high level. Attention should be paid to domestic production. The Singapore Hi - 5 spread reached a new high this year, both 380cst and VLSFO weakened, the domestic FU internal - external spread rebounded slightly, the LU valuation was high, and short - term valuation regression opportunities for FU - LU could be considered [6][7] Data Summary Rotterdam Fuel Oil Swap Data | Product | Change (July 18 - July 24) | |--|--| | Rotterdam 3.5% HSF O Swap M1 | +5.46 | | Rotterdam 0.5% VLS FO Swap M1 | +5.46 | | Rotterdam HSFO - Brent M1 | - 0.35 | | Rotterdam 10ppm Gasoil Swap M1 | - 2.31 | | Rotterdam VLSFO - Gasoil M1 | +7.77 | | LGO - Brent M1 | - 0.77 | | Rotterdam VLSFO - HSFO M1 | 0.00 | [4] Singapore Fuel Oil Swap Data | Product | Change (July 18 - July 24) | |--|--| | Singapore 380cst M1 | +1.49 | | Singapore 180cst M1 | - 3.82 | | Singapore VLSFO M1 | +0.92 | | Singapore Gasoil M1 | +0.63 | | Singapore 380cst - Brent M1 | - 0.31 | | Singapore VLSFO - Gasoil M1 | - 3.74 | [4] Singapore Fuel Oil Spot Data | Product | Change (July 18 - July 24) | |--|--| | FOB 380cst | +2.14 | | FOB VLSFO | +0.27 | | 380 Basis | - 1.00 | | High - Sulfur Internal - External Spread | +0.4 | | Low - Sulfur Internal - External Spread | +0.6 | [5] Domestic FU Data | Product | Change (July 18 - July 24) | |--|--| | FU 01 | +10 | | FU 05 | +15 | | FU 09 | 0 | | FU 01 - 05 | - 5 | | FU 05 - 09 | +15 | | FU 09 - 01 | - 10 | [5] Domestic LU Data | Product | Change (July 18 - July 24) | |--|--| | LU 01 | +31 | | LU 05 | - 6 | | LU 09 | +22 | | LU 01 - 05 | +37 | | LU 05 - 09 | - 28 | | LU 09 - 01 | - 9 | [6]
