Global benchmark prices for very low sulphur fuel oil (VLSFO) have plunged to levels unseen since early 2021, marking a significant inflection point for the maritime fuel and shipping industries.
According to data from Ship & Bunker, the G20-VLSFO Index — covering 20 major bunkering ports — dropped by US $6 per metric tonne to around US $483 / mt in late trading, continuing a six-session streak of declines. Comparable indices for high‐sulphur fuel oil (HSFO) and marine gas oil (MGO) also slid, illustrating broad weakness across marine fuels.
Why the downward spiral?
A confluence of demand and supply forces is driving the downturn in VLSFO pricing. First, shipping demand growth has softened. The International Energy Agency (IEA) warns that global marine-fuel demand may stagnate around 5 million barrels per day through 2030 due to a sluggish economy and tighter climate/clean-fuel regulation.
Second, VLSFO supply appears more comfortable than before: recent reporting shows that bunker supplies of compliant low-sulphur fuel oil are increasingly available, reducing the tightness that earlier supported higher premiums. Third, the premium between VLSFO and alternative fuel grades, including HSFO (for scrubber-fitted vessels) and other fuels, is narrowing.
This removes part of the incentive for ships to burn VLSFO, and shifts the economics of fuel-choice.Finally, regulatory cost pressures are mounting—while the fuel cost drops, compliance and emissions-related costs (especially in regions like Europe) are rising, compressing margins and changing fleet behaviour.
Impact on ship operators & bunkering ecosystem
For ship-owners and charterers, lower VLSFO prices improve voyage economics. Fuel remains one of the largest cost lines in shipping. This gives operators a window of reduced unit fuel cost — but it also forces a reassessment of hedging positions: those who hedged at higher fuel cost levels may see paper losses or reduced benefit from their contracts.
For bunker suppliers and port bunkering hubs, the drop in fuel price translates into tighter margins. As fuel cost pressure grows, suppliers may face cost-squeeze, especially if volumes fall or freight/refuelling logistics become more competitive.
For the broader maritime industry, the downturn raises strategic questions. Investment in fuel-switching or emissions-reduction technologies (such as scrubbers, LNG dual-fuel, methanol/ammonia systems) may be impacted: when VLSFO becomes relatively cheap, the cost-benefit math for alternative fuels lengthens.
Meanwhile, port bunkering volumes may shift: opportunistic refuelling may increase in some hubs, but overall demand softness may reduce volumes. Additionally, while the drop in fuel cost is positive, rising regulatory cost burdens (e.g., carbon pricing, emissions trading) mean total fuel-plus-compliance cost may not fall in tandem.
What stakeholders should watch
Market watchers are forecasting that the VLSFO price decline may continue into 2026, with some models projecting averages in the US $450s/mt range. Key variables to monitor: the shape of global economic growth (impacting trade volumes), refinery output and low-sulphur fuel availability, alternative fuel adoption rates (and thus competition for VLSFO), and regulatory cost frameworks (carbon pricing, emission-control areas).
For maritime charter markets, changes in fuel cost may influence freight rates and time-charter calculations, while bunkering hubs may need to adjust cost / margin strategies to remain competitive.
As Editor in Chief of The Maritime, I lead content development, interviews, and digital storytelling across our multimedia maritime platform. With over 10 years of experience in the maritime industry, I create and publish in-depth stories and video features that highlight key players, emerging trends, and operational realities across global shipping. Before launching The Maritime, I worked as a Vessel Operator at Imza Marine A.S., gaining hands-on commercial shipping and voyage operations experience. I also served as Marketing Communications Specialist at Gimas Ship Supply & Services, where I managed corporate communication, digital strategy, and industry outreach for shipowners and maritime clients. I hold a Master’s degree in Maritime Transportation Management from Istanbul Technical University and a Master’s degree in Publishing from Marmara University. My work is driven by the belief that the maritime world deserves strong, informed, and accessible media representation. I am committed to sharing the stories of maritime professionals and contributing to the sector’s visibility, knowledge exchange, and future development.
