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: Rott B100 discount to LSMGO narrows to $700/mt Singapore B100-LSMGO spread down to $98/mt Traders advise 7–10 days for ARA bio-bunker deliveries LSMGO prices have tumbled over the past week, sharply narrowing B100 and LNG discounts to the fuel in both Rotterdam and Singapore, and LBM discounts in Rotterdam. Rotterdam’s B100 discount to LSMGO has shrunk by $162/mt to $700/mt. LNG’s discount to LSMGO has tightened by $78/mt to $373/mt for vessels with Otto medium-speed engines, and by $75/mt to $609/mt for vessels with diesel slow-speed engines. LBM discounts to LSMGO in Rotterdam have also narrowed by $61–64/mt to $944–1,187/mt, depending on engine type. In Singapore, B100’s discount to LSMGO has narrowed by a slightly smaller $143/mt to $98/mt. LNG discounts have tightened by $105–107/mt to $219–337/mt, depending on the vessel’s engine type.

Dutch ZRE-As are trading in the range of €125-130/mtCO2e, with one source indicating an offer at €135/mtCO2e, Ulrich Arnheiter, market analyst at Prima Markets told ENGINE. Securing biofuel deliveries, including B100, in the ARA requires around 7–10 days of lead time, a trader said. Singapore’s LSMGO price has almost mirrored Rotterdam’s fall, dropping by $122/mt over the past week. The port’s B100 price has risen by $20/mt.
