Introduction

The global bunker fuel market reached a volume of 4.54 million barrels per day (B/d) in 2024. Aided by the increasing demand for maritime transport and evolving environmental regulations, the bunker fuel market size is projected to grow at a compound annual growth rate (CAGR) of 1.80% between 2025 and 2034, reaching a volume of approximately 5.43 million B/d by 2034. As international trade expands and global shipping activities increase, the demand for marine fuels continues to remain robust, even as the industry undergoes a significant transformation towards cleaner alternatives and operational efficiency.

Bunker fuel, also known as marine fuel, is used to power ships and marine vessels. Traditionally, heavy fuel oil (HFO) has dominated the market; however, new environmental mandates such as the International Maritime Organization’s (IMO) 2020 sulfur cap have significantly altered the fuel mix. Low sulfur fuel oil (LSFO), marine gasoil (MGO), liquefied natural gas (LNG), and biofuels are increasingly entering the market, transforming the competitive landscape. As shipowners seek compliance with environmental norms and cost-effective fuel options, bunker fuel suppliers and refiners are responding with a broader, more sustainable product range.

Bunker Fuel Market Size

The global bunker fuel market, with a volume of 4.54 million B/d in 2024, reflects the maritime sector’s continued reliance on fossil fuels despite regulatory and environmental pressures. Bunker fuel constitutes a major operating cost for the shipping industry, and its demand is closely linked to global trade volumes, fleet capacity, and fuel pricing dynamics. As global seaborne trade continues to grow, the bunker fuel market remains integral to the maritime logistics ecosystem.

The market size is also influenced by fuel diversification and the adoption of energy-efficient vessel designs. While heavy fuel oil continues to hold a significant share, the shift towards compliant fuels post-IMO 2020 has expanded the market for marine gasoil and blended alternatives. Additionally, LNG bunkering infrastructure development is steadily increasing, adding further value to the overall market.

Bunker Fuel Market Share

Heavy fuel oil still accounts for a substantial portion of the global bunker fuel market share due to its historical dominance and cost advantage. However, its market share has been gradually declining as shipowners transition to low-sulfur fuels and alternative energy sources in compliance with environmental regulations. Low sulfur fuel oil has witnessed rapid adoption and now represents a significant segment, especially among large vessels operating on international routes.

Marine gasoil holds a notable share due to its compatibility with existing ship engines and its availability in most global ports. LNG, although still in its early stages compared to conventional fuels, is gradually capturing market share, particularly in newly built vessels equipped with dual-fuel engines. Moreover, the emergence of sustainable marine fuels such as biofuels and methanol is beginning to impact market dynamics, though their share remains relatively small for now.

Regionally, Asia-Pacific leads the bunker fuel market, with major bunkering hubs in Singapore, China, and South Korea. Europe and the Middle East follow, with established ports such as Rotterdam and Fujairah playing critical roles. North America also holds a significant share, particularly due to its shipping activities in the Gulf of Mexico and along both coasts.

Bunker Fuel Market Trends

One of the most influential trends shaping the bunker fuel market is the transition toward low-emission and sustainable fuels. Following the IMO 2020 regulation, there has been a global shift towards 0.5% sulfur content fuels, replacing the previously dominant high sulfur fuel oil (HSFO). This trend has accelerated innovation and diversification in the marine fuels sector.

LNG bunkering is gaining momentum, driven by its ability to significantly reduce sulfur oxides (SOx), nitrogen oxides (NOx), and carbon dioxide (CO2) emissions. With several countries investing in LNG infrastructure, this trend is likely to continue over the forecast period. Similarly, alternative fuels such as methanol, ammonia, and hydrogen are receiving increased attention as long-term solutions for decarbonising the maritime industry.

Digitalisation in bunkering operations is another key trend. The integration of data analytics, fuel quality monitoring, and real-time fuel management systems enhances operational transparency and efficiency. Ship operators are increasingly investing in fuel management technologies to track consumption, reduce waste, and comply with environmental standards.

In addition, the growing popularity of scrubber installations, particularly in vessels opting to continue using HSFO, represents a parallel trend. Although the scrubber market has faced criticism, it remains a viable compliance method for many fleet operators seeking to balance fuel costs and regulatory adherence.

Drivers of Growth

The growth of the global bunker fuel market is primarily driven by the increasing demand for maritime transportation. As globalisation deepens and international trade expands, maritime shipping continues to serve as the backbone of global logistics. Consequently, the demand for marine fuels remains resilient, especially in regions with major port activity and dense trade networks.

Regulatory mandates, particularly from the IMO, are encouraging the use of cleaner marine fuels and driving demand for compliant options such as LSFO and MGO. These regulations are not only shaping consumption patterns but also fostering innovation in fuel formulations and ship engine technologies.

Technological advancements in engine designs, which allow for dual-fuel usage or improved fuel efficiency, also contribute to the market’s expansion. Furthermore, increasing investments in LNG and alternative fuel infrastructure are unlocking new opportunities, especially for ports and suppliers involved in LNG bunkering.

Rising environmental consciousness among stakeholders, coupled with pressure from cargo owners and financiers to decarbonise supply chains, is prompting ship operators to explore cleaner fuel options. As a result, demand is diversifying, creating growth opportunities across different bunker fuel segments.
