Report Industry Investment Rating No relevant content provided. Report's Core View - This week, the high - sulfur cracking of Singapore 380cst fluctuated, the near - month spread fluctuated, the basis strengthened slightly, the EW spread rebounded again, and recently showed wide - range fluctuations. The FU internal - external near - month also fluctuated. The low - sulfur cracking rebounded slightly but was at a historically low level year - on - year, the spread was weakly sorted, the LU internal - external price rebounded slightly to $8 - 9 per ton, and the MF0.5 basis fluctuated [3][4]. - From a fundamental perspective, Singapore's residual oil decreased, floating storage fluctuated, ARA residual oil inventory decreased slightly, EIA residual oil decreased slightly, Fujairah inventory decreased, and Middle - East high - sulfur floating storage increased significantly. The high - sulfur Middle - East peak season has passed. Supported by logistics reshaping and Singapore's high - sulfur marine fuel demand, the EW spread has completed its repair. Recently, refinery feedstock procurement has supported the 380 cracking level, with limited short - term downside space. It is expected that the 380 cracking will maintain a fluctuating pattern, and a short - term internal - external bullish view is taken on domestic FU [4]. - This week, the LU market was still weak. The issuance of the third batch of export quotas met expectations, and the external MF0.5 basis fluctuated at a low level. In the fourth quarter, the LU internal - external spread can be enlarged on dips, and attention should be paid to quota usage [4].

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - This week, the high - sulfur cracking of Singapore 380cst oscillated, the near - month spread oscillated, the basis strengthened slightly, the EW spread rebounded again and fluctuated widely recently, and the domestic and foreign near - months of FU oscillated. The low - sulfur cracking rebounded slightly but was at a historical low compared to the same period. The spread was weakly sorted, the domestic and foreign prices of LU rebounded slightly to $8 - 9 per ton, and the MF0.5 basis oscillated. From a fundamental perspective, 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 logistics reshaping and Singapore's high - sulfur marine fuel demand, the EW spread has been repaired. Recently, refinery feedstock purchases have supported the 380 cracking level, and the short - term downward space is limited. It is expected that the 380 cracking will maintain an oscillating pattern, and domestic FU should have a short - term domestic and foreign oscillating and bullish mindset. This week, the LU market was still weak. The issuance of the third batch of export quotas was in line with expectations, and the external MF0.5 basis oscillated at a low level. In the fourth quarter, the domestic and foreign spreads of LU can be expanded on dips, and attention should be paid to the quota usage [3][4]. 3.

Report Summary 1. Report Industry Investment Rating - No content provided regarding the report industry investment rating. 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 slightly weakened to -$0.8. 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][5] - Singapore's land inventory decreased this week, 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, the arrivals oscillated this week, the shipments from the UAE rebounded month - on - month, and the net exports increased significantly. The 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 a large inventory contradiction. [5] - The east - west divergence of high - sulfur continued. In the heavy - oil pattern, the cracking of Singapore 380cst was the weakest, and the premium of heavy - crude oil was the strongest. It is expected to return in both directions later. 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. [5] - In the short term, pay attention to the opportunity of the high - sulfur 380 EW spread widening. Fundamentally, the expected supply of high - sulfur will increase, and the supply - demand pattern will weaken. [5] 3.

Report Investment Rating - No investment rating information is provided in the report. Core Viewpoints - This week, the high-sulfur cracking spread fluctuated downward, the near-month spread declined, and the EW was in a low-level oscillation. The 380 8-9 month spread dropped to $3.25, the basis oscillated at a low level, the FU09 domestic and foreign spread weakened significantly, and the domestic delivery volume was large, maintaining a loose pattern. The Singapore 0.5 cracking spread declined slightly, the month spread oscillated, and the 8-9 month spread oscillated around $6. The LU domestic and foreign spreads remained strong, with the 09 oscillating around $17. This week, Singapore's onshore inventory increased, the window was under delivery pressure, and the near month was under pressure. Recently, fuel oil exports from Iran and Iraq remained at a high level, Egypt's net imports reached a new high, the high-sulfur supply and demand was still in the peak season, the domestic and foreign spreads had dropped rapidly, the foreign low-sulfur valuation was high, and the LU domestic and foreign spreads were running at a high level. Attention should be paid to the domestic production situation.
