Report Industry Investment Rating - Not provided Core Viewpoints - This week, the near - month contract of Singapore 380cst continued to strengthen, reaching a five - year high. After the crack spread rose, it entered a consolidation phase. Short - term arbitrage logistics tightened, and Singapore's residue inventory decreased significantly. The low - sulfur crack spread of MF0.5 declined, reaching a historical low, and the month - to - month spread was at a historical low for the same period.
