Once a week, bunker intelligence platform ENGINE will publish a snapshot of alternative and conventional bunker fuel prices in the world’s two biggest bunkering hubs. The following is the latest snapshot: 27 July 2026 Rotterdam B100 flips to $110/mt premium over VLSFO Singapore B100 loses cost edge against LSMGO LBM swings to $25/mt premium over VLSFO for Otto MS engines OceanScore’s FuelEU pooling price index has fallen to €131.75/mtCO2e ($150/mtCO2e), down by around €28/mtCO2e ($32/mtCO2e) over the past week. Over the same period, ENGINE-assessed FuelEU Maritime pooling values for B100 and liquefied biomethane (LBM) on EU-EU voyages have decreased by $86/mt and $120-140/mt, respectively. The retreat has been steeper over the past month, but most of it has come in the past week. OceanScore’s FuelEU pooling price index has slumped by €40/mtCO2e ($46/mtCO2e) since 29 June, with roughly 70% of that fall coming in the past week. The drop in the underlying benchmark has cut B100’s potential pooling value by $123/mt in the past month to $405/mt. LBM has been hit even harder, with its pooling values sliding by $171-201/mt over the same period to $562-659/mt. Liquid fuels The decline in B100’s pooling value for EU-EU voyages has hurt the fuel’s affordability in Rotterdam, where its bunker price has climbed by $144/mt over the past week. As a result, B100 has moved to a $110/mt premium over Rotterdam’s VLSFO from a $105/mt discount seen the week before. B100’s discount to LSMGO has narrowed by $201/mt to $340/mt over the past week, with a $57/mt decline in Rotterdam’s LSMGO price adding to the contraction. Singapore’s HSFO and VLSFO benchmarks have edged down by $6-7/mt, while its LSMGO price has declined by $17/mt over the past week. The port’s B100 benchmark has gained $91/mt, driven by a rise in the outright price and a $43/mt drop in B100’s pooling value for EU-nonEU voyages. Singapore’s B100 has shifted to a $2/mt p
