Report Industry Investment Rating - Not provided Core Viewpoints - This week, the high-sulfur crack spread fluctuated and declined, the near-month spread decreased, and the EW continued to weaken. The 380 8-9 month spread weakened to $1.75, the basis weakened and then fluctuated, the FU09 internal and external spread rebounded slightly, and the domestic delivery volume was large, maintaining a loose pattern. The Singapore 0.5 crack spread declined slightly, the month spread weakened, and it fluctuated around $4.5 for the 8-9 month. The LU internal and external spread weakened slightly and then fluctuated, with the 09 around $16. [6][7] - This week, Singapore's onshore inventory increased significantly, the window was under delivery pressure, and the near-month contract was under pressure. Saudi Arabia's 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 and demand were still in the peak season. However, the East-West and internal-external spreads have quickly declined. The external low-sulfur valuation is high, and the LU internal and external spread is running at a high level. Attention should be paid to the domestic production situation. [7] - The Singapore Hi-5 spread reached a new high this year, both 380cst and VLSFO weakened. The domestic FU internal and external spread rebounded slightly, and the LU valuation is high. Attention can be paid to the short-term valuation regression opportunity of FU-LU, with the risk being the continuous weakening of the external 380cst.
