The global bunker market entered a phase of relative stabilisation during Week 20, although mixed price fluctuations continued to persist. At the same time, the volatility amplitude narrowed considerably compared to previous periods. By the end of the week, the 380 HSFO index declined by US$ 6.17, falling from US$ 782.82/MT last week to US$ 776.65/MT. In contrast, the VLSFO index recorded a moderate increase of US$ 4.44, rising from US$ 939.45/MT to US$ 943.89/MT. Meanwhile, the MGO LS index decreased by US$ 6.57, from US$ 1,410.57/MT last week to US$ 1,404.00/MT. At the time of writing, mixed movements remained the dominant trend across the global bunker market. According to Sergey Ivanov , the market continues to remain highly sensitive to geopolitical developments and supply concerns. The MABUX Global Scrubber Spread (SS) — the price differential between 380 HSFO and VLSFO — recorded a moderate increase of US$ 10.61, rising from US$ 156.63 last week to US$ 167.24, and remaining comfortably above the psychological threshold of US$ 100.00 (SS Breakeven). The weekly average of the index also advanced by US$ 4.69. In Rotterdam, the SS Spread contracted sharply by US$ 35.00, declining from US$ 131.00 last week to US$ 96.00 and falling below the US$ 100.00 breakeven level. At the same time, the port’s weekly average SS Spread increased by US$ 6.16. In Singapore, the 380 HSFO/VLSFO spread narrowed marginally by US$ 1.00, from US$ 126.00 last week to US$ 125.00. During the week, the spread temporarily dropped to US$ 87.00, while the weekly average in the port increased by US$ 4.34. Overall, the SS Spread lacked a clear directional trend throughout the week. Nevertheless, values remaining predominantly above the US$ 100.00 threshold continued to support the strong economic attractiveness of scrubber usage in combination with 380 HSFO versus conventional VLSFO consumption. Despite ongoing relative stability, bunker fuel price volatility remains elevated, which may create c
