Report Summary 1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst rebounded and then weakened, the near - month spread oscillated, and the EW spread oscillated. The 9 - 10 spread weakened to $3.5/ton, the basis oscillated at a low level (-$4), and the FU01 internal - external spread weakened slightly to -$0.8 [4]. - The 0.5 cracking of Singapore oscillated and weakened, the 9 - 10 spread weakened to $2.75/ton, and the LU11 internal - external spread oscillated at $9 [4]. - This week, Singapore's on - land inventory decreased, but it was still not the highest in the same period of history. The floating storage decreased significantly month - on - month, Saudi Arabia's shipments decreased significantly, this week's arrivals oscillated, the UAE's shipments rebounded month - on - month, and net exports increased significantly [5]. - The on - land inventory in Fujairah, the Middle East, decreased, the floating storage inventory of high - sulfur and low - sulfur increased significantly, the ARA residue inventory increased, and the US residue inventory decreased, with significant inventory contradictions [5]. - The east - west divergence of high - sulfur continued. In the heavy - quality pattern, the cracking of Singapore 380cst was the weakest, and the premium of heavy - quality crude oil was the strongest. It is expected to return in both directions later [5]. - This week, LU remained weak, the basis of the external MF0.5 weakened again and then oscillated, the LU quota was issued, and the internal - external spread oscillated. In the short term, pay attention to the opportunity of the high - sulfur 380 EW spread widening. Fundamentally, the supply of high - sulfur is expected to increase, and the supply - demand pattern will weaken [5]. 3.

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core Viewpoints of the Report - 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 FU01 internal - external spread strengthened slightly to $2.5. The cracking spread of Singapore 0.5% low - sulfur fuel oil continued to weaken, the 9 - 10 spread rebounded slightly to $3.75/ton, and the LU11 internal - external spread oscillated around $8. [5][6] - This week, Singapore's on - shore inventory increased significantly, reaching the highest level in the same period of history. Floating storage increased month - on - month. Saudi Arabia's shipments were at a historical high for the same period, and arrivals rebounded this week. UAE's shipments rebounded significantly month - on - month, and net exports increased substantially. [6] - The divergence between the East and West of high - sulfur fuel oil continued. 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 to converge in both directions later. [6] - This week, LU's weakness was realized, the spot price of the external MF0.5 decreased slightly, and the valuation was realized. Attention should be paid to the subsequent release of LU quotas. Pay attention to the opportunity of the high - sulfur 380 EW spread to widen, and short - term short positions in LU should exit.

Report Summary 1. Report Industry Investment Rating No clear industry investment rating is provided in the report. 2. Core View - The Asian low - sulfur fuel oil market structure has strengthened slightly due to the expected tight supply in June. The supply of compliant low - sulfur fuel oil is expected to be limited in the next two weeks due to the lack of medium - sulfur blending components. The high - sulfur fuel oil market is supported by the increasing power generation demand as the Middle East and South Asia enter the peak air - conditioning electricity consumption season. - The spot prices of both high - sulfur and low - sulfur fuel oils are at a premium to the futures prices. - The Singapore fuel oil inventory decreased by 610,000 barrels to 21.409 million barrels in the week ending June 4. - The prices of fuel oil are above the 20 - day moving average, and the 20 - day moving average is flat. - Both high - sulfur and low - sulfur fuel oil main contracts have short positions, and the short positions are decreasing. - Overnight, with the improvement of the macro - sentiment, the financial market strengthened. Fuel oil followed the upward trend of crude oil, and the fundamentals are slightly strong. It is expected to perform better than crude oil today. The FU2507 is expected to trade in the range of 2930 - 2990, and the LU2508 is expected to trade in the range of 3530 - 3590 [3]. 3. Summary by Directory 3.1 Daily Prompt - The report provides a comprehensive analysis of the fuel oil market, including fundamentals, basis, inventory, price trends, and main contract positions. It also gives the expected trading ranges for the FU2507 and LU2508 contracts [3]. 3.2 Multi - and Short - term Concerns - **Likely Positives**: OPEC+ has extended additional production cuts (though implementation needs to be tracked), and China has issued import quotas. - **Likely Negatives**: The optimism on the demand side remains to be verified, and there is a possibility of relaxed sanctions on Russia. The market is driven by the co - existence of supply - side production cuts that need to be observed and neutral demand [4]. 3.3 Fundamental Data - **Supply**: The supply of low - sulfur fuel oil is expected to be tight in the short term due to the lack of blending components. The high - sulfur fuel oil market is supported by power generation demand. - **Basis**: The basis of Singapore high - sulfur fuel oil is 261 yuan/ton, and that of low - sulfur fuel oil is 201 yuan/ton, indicating a spot premium over futures. - **Inventory**: The Singapore fuel oil inventory decreased by 610,000 barrels to 21.409 million barrels in the week ending June 4 [3]. 3.4 Spread Data - The report does not provide detailed spread data analysis, but shows a chart of the high - and low - sulfur fuel oil futures spread over a long - term period [14]. 3.5 Inventory Data - Singapore fuel oil inventory data from March 26 to June 4 is provided, showing fluctuations in inventory levels. The inventory decreased by 610,000 barrels in the week ending June 4 [8].
