ENGINE on Fuel Switch Snapshot: B100 and LNG sharpen price edge in Singapore

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:

• B100’s premium over VLSFO drops in Singapore
• Rotterdam LBM sales hit 2,000 mt in Q2
• LNG-VLSFO spread shifts across engine types

In Rotterdam, B100’s discount to VLSFO has narrowed by $15/mt over the past week to $158/mt.

On the other hand, B100 has become slightly less expensive than VLSFO in Singapore, with its premium falling by $56/mt to $463/mt after accounting for estimated pooling values on voyages between Singapore and EU ports.

Rotterdam LNG’s premium over VLSFO for dual-fuel vessels with Otto medium-speed (Otto MS) engines has narrowed by $15/mt to $69/mt. For vessels with diesel slow-speed (diesel SS) engines, LNG is now $14/mt cheaper than before, widening its discount to $97/mt below VLSFO.

LNG’s premium over liquefied biomethane (LBM) in Rotterdam has remained largely unchanged over the past week, ranging between $152-201/mt depending on engine type.

In Singapore, LNG’s premium over VLSFO for dual-fuel vessels with Otto MS engines has nearly halved to $57/mt. For vessels with diesel SS engines, LNG has flipped to a $26/mt discount over VLSFO in the past week, from a $25/mt premium the week prior.

Liquid fuels

Rotterdam’s VLSFO price has remained unchanged over the past week. Prompt supply continues to be tight in the ARA hub, a trader told ENGINE, with recommended lead times of 5–6 days.

B100 (HBE) price in Rotterdam has increased by $15/mt. The port’s bio-blended bunker sales reached 171,000 mt in the second quarter of this year, a 56% rise from the first quarter.

Singapore’s VLSFO price has remained almost steady in the past week, edging higher by $3/mt.

VLSFO lead times remain highly inconsistent in Singapore. While some suppliers can deliver within seven days, others advise booking up to four weeks in advance due to long-term nominations. These are typically contract-based orders that take precedence over spot inquiries. Limited stock availability and pending replenishments are also contributing to delays.

Singapore’s B100 (UCOME) price has fallen by $54/mt, largely due to weaker feedstock prices. The port’s total bio-blended bunker sales surged by 12% in June to 155,000 mt, while its B100 sales reached 1,000 mt.

Liquid gases

Rotterdam’s LNG bunker price has declined by $15/mt in the past week, slightly greater than the $12/mt decline in the port’s LBM benchmark.

The port’s LBM sales reached a record 2,000 mt in the second quarter of 2025, following a lull in the first quarter. 

Singapore’s LNG price has seen a deeper cut at $49/mt in the past week. The port’s LNG sales rose for the fourth consecutive month, reaching a record 55,000 mt in June.
