Report Summary 1. Report Industry Investment Rating No information provided. 2. Core View of the Report - This week, the high - sulfur crack in Singapore oscillated, the monthly spread strengthened slightly, and the basis weakened. The HSFO crack in Europe declined, and the EW strengthened this week. The 0.5% crack in Singapore rebounded, the monthly spread oscillated, and the basis oscillated at a low level. In terms of inventory, Singapore's residual oil decreased slightly, ARA's residual oil increased, Fujairah's residual oil increased, and EIA's residual oil inventory remained flat. The spread between high - and low - sulfur in the outer market rebounded. Singapore's high - sulfur is supported by EW and refinery purchases, but the spot basis is weakening rapidly. It is in a short - term oscillatory pattern, and the short - term downward space for low - sulfur is limited. [6][7] 3.
