Fuel Switch Snapshot: B100–LBM spreads tighten sharply in Rotterdam

B100 premiums over LBM drop to $87-303/mt

Rotterdam’s B100 over $500/mt cheaper than LSMGO

LNG’s discounts to LSMGO narrow sharply

All bunker prices described in the text below have been adjusted for calorific contents to make them VLSFO-equivalent. They have estimated EU-EU voyage compliance costs included for Rotterdam, and nonEU-EU compliance costs included for Singapore. These account for EU ETS costs and FuelEU Maritime penalties, and the average price of compliance surpluses we have picked up from the FuelEU pooling market from the past week. 

A whopping $104/mt drop in Rotterdam’s B100 price has sharply narrowed its premiums over the port’s 0 gCO2e/MJ liquefied biomethane (LBM) benchmark.

B100’s premium over LBM when bunkered on vessels with diesel slow speed (diesel SS) engines has dropped by $169/mt to $303/mt. For vessels with Otto medium speed (Otto MS) engines, the premium has narrowed by $172/mt on the week, to $87/mt.

On the other hand, B100 has become drastically cheaper compared to conventional fuels in Rotterdam.

B100’s discount to VLSFO has widened by $132/mt to $357/mt over the past week, and its discount to LSMGO has widened by $131/mt to $520/mt.

Conventional fuels still retain cost advantages against B100 in Singapore. HSFO and LSMGO discounts to B100 have inched lower by $1–11/mt, while VLSFO’s discount to B100 has edged up by $2/mt in the past week.

Liquid fuels

Rotterdam’s conventional fuel benchmarks have jumped $27–28/mt higher over the past week. Its VLSFO price rise has outpaced a $6/mt rise in front-month ICE Brent futures.

HSFO and LSMGO deliveries are readily available with short notice of 2–4 days in the ARA bunkering hub. But VLSFO supplies may require longer lead times of more than a week, a trader told ENGINE.

Rotterdam’s B100 price has slumped $104/mt lower over the past week, with some support from higher Dutch ZRE A ticket prices. The assessed ZRE A ticket price has gone up from €155/mtCO2e ($531/mtB100) a week ago to €164/mtCO2e ($560/mtB100) now.

The B100 price drop has reduced the effective cost of bunkering and consuming the fuel on EU-EU voyages to $488/mt.

Singapore’s B100 price has gained $19/mt over the past week.

The port’s B100 sales have increased from zero in 2024 to 26,000 mt in 2025, according to preliminary data from the port authority.

Liquid gases

LNG prices in Rotterdam (+$78–80/mt) and Singapore (+$89–90/mt) have risen sharply over the past week, depending on a vessel’s engine type.

The surges have come as both the front-month Dutch TTF natural gas contract and the front-month NYMEX JKM contract have spiked amid heightened geopolitical concerns and forecasts of colder temperatures across northwest Europe and northeast Asia.

LNG’s discounts to LSMGO in Rotterdam have narrowed by $50–53/mt over the past week to $28–269/mt. Its discounts to LSMGO in Singapore have decreased by $69–70/mt to $11–131/mt.

Rotterdam’s 0 gCO2e/MJ LBM has jumped $66–68/mt higher over the past week. That has not kept up with the port's LNG price rise, and LBM's discounts to LNG have widened by $11–12/mt to $576–587/mt.
