ENGINE on Fuel Switch Snapshot: B100 and LBM mostly stable across key ports

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:

29 September 2025

• Rotterdam’s B100 at $143-362/mt discounts to conventional fuels
• LBM cheapest for low-methane-slip engines
• LNG at $165-169/mt premiums over LBM in Rotterdam

EU regulations mean that B100 can make sense on EU-EU voyages, but not so much on Singapore-EU voyages.

Rotterdam’s HBE-rebated B100 stands at discounts of $143/mt to HSFO, $179/mt to VLSFO and a sharp $362/mt to LSMGO.

Singapore’s B100, meanwhile, is priced $469/mt over its VLSFO even after factoring in biofuel benefits for a voyage between Singapore an an EU port.

For dual-fuel ships with Otto medium-speed (Otto MS) engines, LNG sits at a $39/mt premium over VLSFO in Rotterdam, and a $20/mt premium in Singapore.

But for vessels with diesel slow-speed (diesel SS) engines, LNG shifts to discounts of $64/mt in Rotterdam and $32/mt in Singapore.

Liquefied biomethane (LBM) is the cheapest option for vessels with diesel slow-speed engines. It is even priced $54/mt below B100 in Rotterdam, though it flips to a $53/mt premium over B100 for vessels with Otto MS engines.

Rotterdam’s LBM is priced $126–230/mt below its VLSFO, depending on engine type.

Liquid fuels

Rotterdam’s VLSFO price has edged $4/mt lower in the past week. Availability of all conventional bunker grades in the wider ARA region remains stable, a trader said. 

Rotterdam’s B100 benchmark has inched up by $3/mt over the same period, mainly driven by a $6/mt decline in Dutch HBE rebates for marine B100. The Prima Markets-assessed B100 rebate has paused its recent rise and eased over the past week.

Singapore’s VLSFO has also remained almost steady, rising $6/mt in the past week. Availability of the grade remains steady in the port, with traders recommending lead times of 7–10 days. The port’s B100 price has gained $8/mt in the past week.

Liquid gases

Rotterdam’s LNG bunker price has lost $6/mt in the past week, while its LBM benchmark has inched slightly lower by $2/mt.

LNG prices have been under some downward pressure in Rotterdam. The LNG bunker delivery premium has come off slightly to $136/mt, while front-month TTF has held steady at $579/mt. Lower temperatures have stimulated more gas demand in Europe, while steady Norwegian gas supply has contributed to keep prices in check.

Singapore’s LNG price has remained almost unchanged, with only a $1/mt decline in the past week. A near $5/mt rise in Singapore’s LNG bunker delivery premium has been countered by a $4/mt decline in the front-month JKM contract.

Northeast Asian LNG demand remains weak, and inventories are well-stocked, says JOGMEC. Steady fundamentals have kept prices in check, it argues.
