Fuel Switch Snapshot: Conventional fuels slump in major ports

June 15, 2026

HSFO becomes cheaper than B100 in Rotterdam

Singapore’s B100 flips to premium over LSMGO

Rotterdam LBM discounts to LNG widen

All bunker prices described in the text below have been adjusted for calorific content 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.


Brent’s price has slumped by $14.73/bbl ($108/mt) on the week after US President Donald Trump announced a preliminary peace deal with Iran yesterday. The sharp decline has dragged conventional fuel prices lower in both Rotterdam and Singapore.

Rotterdam's B100 has shifted to a $14/mt premium over HSFO, from a $1/mt discount seen a week ago.

B100 discounts to VLSFO and LSMGO have narrowed by $54/mt and $89/mt to $50/mt and $343/mt, respectively.

In Singapore, B100 has shifted from a $79/mt discount to LSMGO to a $16/mt premium.



Rotterdam’s liquefied biomethane (LBM) discounts to its LSMGO have narrowed by $21-28/mt in the past week, to $639-844/mt, depending on the LNG engine type.

Liquid fuels

Rotterdam's HSFO (-$71/mt) and VLSFO (-$110/mt) prices have to some extent tracked a $14.73/bbl ($108/mt) drop in front-month ICE Brent futures. Its LSMGO benchmark has fallen by $145/mt, exceeding a $125/mt decline in front-month ICE low sulphur gasoil futures.

The port's B100 price has dropped by $56/mt over the past week. Dutch ZRE A ticket prices have edged down by €2/mtCO2e to €108/mtCO2e.

Singapore's conventional fuel prices have fallen by $112-167/mt, and its B100 price by $72/mt.

Liquid gases

Rotterdam's LNG bunker prices have dropped by $77-83/mt in the past week, largely tracking a 12% decline in the front-month Dutch TTF Natural Gas contract.

Its LBM prices have fallen by $117-124/mt. LBM discounts to LNG have widened by $40-41/mt to $455-462/mt in the past week.

Singapore's LNG prices have risen by $13-16/mt. The rises came amid spot market demand from India for fertiliser plants, power generation and households, noted ANZ Bank's Daniel Hynes. Japan and South Korea tend to import more gas for power generation during their summer months, and China has been active in the market, Hynes said.
