The global bunker market remained broadly stable during Week 21, with limited price fluctuations shaping overall market dynamics. The 380 HSFO index increased by US$16.69, rising from US$776.06/MT to US$791.75/MT and approaching the psychological US$800 mark once again. The VLSFO index also moved higher, gaining US$8.91 week-on-week to US$952.60/MT, compared to US$943.69/MT the previous week. Meanwhile, the MGO LS index recorded a smaller increase of US$1.96, advancing from US$1,416.43/MT to US$1,418.39/MT. At the time of writing, the global bunker market continued to display mixed and irregular price movements, with no clear directional trend emerging. The MABUX Global Scrubber Spread (SS) — the price differential between 380 HSFO and VLSFO — narrowed by US$7.78 over the week, declining from US$168.63 to US$160.85. Despite the drop, the spread remained comfortably above the psychological US$100.00 breakeven threshold for scrubber economics. The weekly average of the index edged higher by US$2.08. In Rotterdam, the SS Spread remained largely unchanged, increasing marginally by US$1.00 from US$73.00 to US$74.00, while the port’s weekly average spread declined by US$33.33. In Singapore, the 380 HSFO/VLSFO spread widened by US$8.00, rising from US$150.00 to US$158.00, while the weekly average in the port gained US$42.50. Sergey Ivanov, Director of MABUX, said spread levels above US$100.00 continue to indicate stronger cost efficiency for scrubber-equipped vessels consuming 380 HSFO compared to vessels operating on conventional VLSFO. He added that mixed and irregular fluctuations in the SS Spread are likely to continue amid the current relative stability in the bunker market. The Istanbul ECA Spread (ES) resumed its downward movement by the end of the week, declining by US$25.00 from US$75.00 to US$50.00 after briefly reaching the US$100.00 level during the reporting period. However, the weekly average of the index increased by US$17.50. The Venice ECA Spread remains s
