ENGINE on Fuel Switch Snapshot: B100 discounts to conventionals narrow in Rotterdam

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’s discount to LSMGO drops by nearly $200/mt
• LNG premiums over LBM narrow in Rotterdam
• Singapore B100’s discount to LSMGO below $250/mt

Rotterdam’s B100 discount to VLSFO has narrowed by $87/mt, while its discount to LSMGO has dropped by a sharper $197/mt over the past week.

LNG discounts to LSMGO in Rotterdam have also narrowed by $68-72/mt to $399-595/mt.

At the same time, LNG premiums over liquefied biomethane (LBM) sold at 0 gCO2e in Rotterdam have eased by $30/mt to $364-370/mt, depending on engine type and methane slip.

Singapore B100’s discount to LSMGO has narrowed for another week, falling by $302/mt to $241/mt for EU-bound voyages.

For dual-fuel vessels bunkering in Singapore and sailing to the EU, B100 premiums over LNG have widened by $132-134/mt, depending on engine type.

Liquid fuels

Rotterdam’s conventional fuel prices have declined for a fourth consecutive week. VLSFO and HSFO prices have dropped by $20–76/mt, tracking a $113.40/mt ($6.92/bbl) fall in front-month ICE Brent futures, while LSMGO has fallen more sharply by $131/mt.
