Report Key Points 1. Report Industry Investment Rating - Not provided in the given content. 2. Core View of the Report - This week, the cracking spread of high - sulfur fuel oil in the outer market fluctuated, the 380 - grade monthly spread weakened, the 380 - grade basis fluctuated at a high level, and there was pressure on the inside - outer market of FU. In terms of fundamentals, there was a significant inventory build - up in Singapore, a drawdown in ARA, an inventory build - up in EIA onshore, an increase in floating storage, a significant drawdown in high - sulfur floating storage in the Middle East, a drawdown in both onshore and floating storage in Fujairah, and a drawdown in floating storage in Singapore. Saudi Arabia's shipments rebounded month - on - month, while the UAE's shipments decreased month - on - month. In 2025, attention should be paid to the increase in global heavy - oil valuation due to sanctions on Iran. In the Asian region, attention should be paid to whether Russian supply will return to the benchmark. Recently, the decline in floating storage in the Middle East and the onshore inventory build - up in Singapore have put pressure on the near - term monthly spread of 380 - grade fuel oil. For low - sulfur fuel oil, the situation in Singapore is weak. This week, the basis fluctuated at a low level, and the inside - outer price spread also fluctuated at a low level. Global heavy - oil supply remains tight, and the supply of 380 - grade standard products is still tight. If the window rules remain unchanged, the inside - outer market is expected to remain weak in summer, and the domestic market will fluctuate around the fundamentals of downstream demand. [1] 3.
