ENGINE on Fuel Switch Snapshot: High Dutch rebates tilt the scales for B100

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 HBE rebate surges nearly $130/mt since 1 August
• HBE surge puts pressure on Rotterdam B100
• Singapore’s LNG–VLSFO spreads rise $10–11/mt

Soaring Dutch rebates have helped soften Rotterdam’s bio-bunker prices over the past month.

The Dutch HBE rebate for marine B100 has surged by a whopping $129/mt since 1 August, according to Prima Markets. This rise appears to have pushed Rotterdam’s B100 bunker price sharply lower by $95/mt to $1,100/mt over the same period.

Rotterdam’s B100 discount to VLSFO has widened further by $4/mt to $179/mt. Its discount to LSMGO, however, has slightly narrowed by $6/mt to $325/mt.

B100’s discount to LNG in Rotterdam has also widened by a modest $2/mt to $110–218/mt, depending on vessel’s LNG engine type.

In Singapore, B100’s premium over VLSFO has increased by $12/mt to $464/mt.

Liquid fuels

Rotterdam’s VLSFO price has increased by $8/mt in the past week. Availability of all fuel grades is stable in the ARA bunkering hub this week. Buyers are advised to enquire about stems 3-4 days in advance for LSMGO, and 5-7 days in advance for VLSFO and HSFO, to secure good coverage from suppliers.

Singapore’s VLSFO price has decreased by $10/mt, while its B100 price has inched up by $1/mt over the past week.

Conventional fuel bunker demand in Singapore has been good so far this week, according to a source. VLSFO delivery times now vary significantly by supplier — some can meet orders within eight days, while others require bookings nearly two weeks in advance. This marks a tightening from last week’s 8–11-day range.

Liquid gases

Rotterdam’s LNG and liquefied biomethane (LBM) bunker prices have both risen by $8/mt each over the past week.

LBM’s discount to LNG has remained almost unchanged over the past week, at $153–167/mt.

Singapore’s LNG bunker price has edged up by $1/mt in the past week.

For dual-fuel vessels bunkering in Singapore, LNG–VLSFO spreads have moved $10–11/mt higher from last week. LNG is now priced at a $70/mt premium over VLSFO for ships with Otto medium-speed engines, and at a $15/mt discount for slow-speed engines.
