Fuel Oil Market

Overview

The global Fuel Oil Market was valued at USD 162.4 billion in 2025 and is projected to reach USD 190.7 billion by 2034, growing at a CAGR of 1.8% during the forecast period (2026–2034). The growth in the market is driven by steady marine bunker consumption, scrubber-fitted fleets that favour high sulphur grades, and the continued use of residual fuel oil for power generation and industrial boilers in energy-short economies. Fuel oil is the heavy residual fraction left after crude oil distillation and conversion, sold in grades defined by sulphur content and viscosity under the ISO 8217 marine fuel standard, and used mainly in ship engines, thermal power plants, and industrial furnaces. The market is shifting from standard high sulphur residual fuel toward low sulphur blends, hydroprocessed residue streams, and bio-blended grades that meet tighter emission and carbon rules. Government initiatives such as the IMO's 0.50% global sulphur cap under MARPOL Annex VI and its Carbon Intensity Indicator rating scheme for ships are pushing suppliers to improve blending, quality control, and traceability. By region, Asia-Pacific held the largest share of the market in 2025 at 47%, led by bunkering and refining activity in Singapore, China, Japan, and South Korea. Middle East and Africa is expected to be the fastest-growing region during the forecast period, backed by growth in Fujairah bunkering and storage, new refining capacity, and fuel oil use in power systems.

Market Size & Share

Market Dynamics

KEY MARKET TREND

Bio-Blended Fuel Oil and Lower-Carbon Specifications Emerging as a Transformational Trend

• Refiners and bunker suppliers are blending low sulphur fuel oil with used cooking oil methyl ester to create B24 and B30 grades. These blends run in existing ship engines without retrofits, so shipowners can cut lifecycle emissions while keeping the same familiar fuel handling, storage, and treatment routines on board.
• Refineries are also co-processing renewable feedstock inside existing conversion units, which produces drop-in low-emission fuel oil from the same tanks and pipelines. This route lowers the capital needed to scale cleaner grades and gives refiners a practical way to defend fuel oil volumes as carbon intensity rules tighten on major trading lanes.
• Large integrated suppliers with blending terminals, ISCC-certified supply chains, and long-term shipping customers are gaining an edge over smaller blenders. Certification, traceability, and fuel quality testing now strongly shape contract awards as much as price, which pushes the industry toward fewer and better-equipped suppliers at the main bunkering hubs worldwide.
• The IMO's Marine Environment Protection Committee voted 57 to 49 to adjourn adoption of its Net-Zero Framework for one year. The pause keeps the proposed global fuel standard and emissions pricing on hold, so suppliers and shipowners must plan fuel purchases without a fixed worldwide carbon rule.

KEY MARKET DRIVER

Resilient Marine Bunker Demand and Scrubber-Led High Sulphur Fuel Oil Use Driving Market Growth

• Shipping moves around 90% of world trade, and residual fuel oil remains the lowest-cost fuel for large two-stroke engines. This cost advantage keeps bunker buyers loyal to fuel oil even as alternative fuels gain attention, because most of the global fleet cannot change engines, fuel tanks, or treatment systems quickly.
• Ships fitted with exhaust gas cleaning systems can burn high sulphur fuel oil, which trades at a discount to very low sulphur grades. When the price gap widens, owners with scrubbers shift volume toward the cheaper fuel, adding demand for refiners that run complex conversion units and can supply high sulphur grades.
• The 2024 edition of the ISO 8217 marine fuel standard gives buyers clearer limits for residual grades, bio-blends, and contaminants. Clearer, uniform specifications reduce disputes over off-spec cargoes, build confidence in new blends, and help suppliers qualify fuel for term contracts with large container, tanker, and bulk shipping operators worldwide.
• Singapore's Maritime and Port Authority reported record bunker sales for 2025, with high sulphur fuel oil up 7.8% to about 21.7 million tonnes. This was the fifth straight annual rise for the grade at the world's largest bunkering hub, confirming that conventional fuel oil still carries most of global marine demand.

KEY MARKET OPPORTUNITY

Fuel Switching in Energy-Constrained Power Markets Creating New Demand for Fuel Oil

• Import-dependent economies in South Asia, Africa, and the Middle East keep fuel oil-fired units as backup capacity when gas or LNG supply falls short. Utilities that once planned to retire these plants now hold them in reserve, which creates a steady call on residual fuel oil during peak demand and supply shocks.
• Mines, island grids, and remote industrial plants running medium-speed engines and boilers remain largely untapped by cleaner fuels. Fuel oil offers high energy density at a lower cost per unit than distillates, so these users can give suppliers stable, repeat volumes under multi-year contracts. Reliable on-site storage also suits remote locations.
• Suppliers can build new revenue by bundling fuel oil with storage, blending, quality testing, and scheduled delivery in a single long-term service contract. Investors find this model attractive because it earns margin from logistics and fuel quality rather than commodity price swings alone, and it ties customers to long-term relationships.
• Platts reported that Pakistan's fuel oil-fired power generation more than doubled to about 215 GWh in July 2026, after disrupted LNG supply from Qatar left gas-fired plants short of fuel. The data shows how quickly utilities turn to fuel oil during gas shortages, even where policy has discouraged its use.

Segmentation Analysis

Analysis by Sulphur Content

Very Low Sulphur Fuel Oil held the largest market share in 2025 because it became the default compliant fuel for ocean-going ships after the IMO 0.50% global sulphur limit took effect in January 2020. Refiners have since tuned blending pools, tank segregation, and quality control to produce stable very low sulphur grades, and nearly every major bunkering port now lists it as a standard product. Shipowners without scrubbers rely on it for main engines, and large container and tanker operators buy it under term contracts, which gives suppliers predictable volumes. Wide availability across hubs in Asia, Europe, and the Americas keeps it ahead of the other sulphur categories in revenue terms.

High Sulphur Fuel Oil is projected to grow at the fastest CAGR during the forecast period, as more vessels fitted with exhaust gas cleaning systems return to the cheaper grade. The price gap between high sulphur and very low sulphur fuel keeps the payback on scrubbers attractive, and demand also gets a lift from power plants and industrial users that can handle higher sulphur content. Complex refineries with residue upgrading units are expanding output of this grade, while ports are adding storage and barge capacity to handle it. These factors point to steady volume gains and improving revenue for suppliers that hold reliable high sulphur supply.

Sulphur Content categories include

• Very Low Sulphur Fuel Oil (Dominating Segment)
• High Sulphur Fuel Oil (Highest CAGR Segment)
• Low Sulphur Fuel Oil
• Ultra Low Sulphur Fuel Oil

Analysis by Viscosity Grade

The Above 180 to 380 cSt category held the largest market share in 2025 because the 380 cSt grade is the most widely traded residual fuel for main engines on large merchant ships. Container carriers, bulk carriers, and tankers specify it in term contracts, and bunker suppliers stock it at nearly every major port. ISO 8217 treats this range as a core residual class, which simplifies purchasing, testing, and claims handling. Power plants and industrial users with heated storage also buy this viscosity range for large boilers and slow-speed engines, adding a second source of steady demand beyond shipping.

The 180 cSt and Below category is projected to grow at the fastest CAGR during the forecast period, as low sulphur blends that use distillate cutter stocks tend to be lighter and easier to handle. Smaller coastal vessels, auxiliary engines, and medium-speed power engines favour lower viscosity because it reduces heating needs and filter problems. Bio-blended grades also tend to land at lower viscosity, which supports their use in existing fuel systems. As suppliers widen blended product ranges to meet emission rules, this category is taking a larger share of new term contracts and spot tenders.

Viscosity Grade categories include

• 180 cSt and Below (Highest CAGR Segment)
• Above 180 to 380 cSt (Dominating Segment)
• Above 380 cSt

Analysis by Application

Marine Bunkering held the largest market share in 2025 because ocean-going ships still run mostly on residual fuel oil, and global bunkering hubs keep adding supply points, barges, and storage. The IEA expects global bunker demand to stay near 5 million barrels per day through 2030, which shows how steady this base is. Regulations such as the IMO sulphur cap and the carbon intensity rating system shape the fuel mix but have not removed fuel oil from the main engine room. Long-term supply agreements between refiners and shipping lines further lock in volume.

Power Generation is projected to grow at the fastest CAGR during the forecast period, as import-dependent economies keep fuel oil-fired plants ready for peak load and gas supply gaps. Rapid electricity demand growth in Africa, South Asia, and parts of the Middle East outpaces grid and renewable build-out, so utilities rely on flexible thermal units. Fuel oil can be stored on site for weeks, which gives power producers an energy security buffer that pipeline gas or LNG cannot always match. Rising investment in captive plants for mines and industrial parks adds another layer of demand.

Application categories include

• Marine Bunkering (Dominating Segment)
• Power Generation (Highest CAGR Segment)
• Industrial Heating
• Others

Analysis by Production Route

Blended Fuel Oil held the largest market share in 2025 because most marine fuel sold today is formulated by mixing residue with distillate and cutter stocks to hit sulphur and viscosity targets. Blending lets suppliers use whatever refinery streams are available, adjust to port-specific demand, and respond fast to specification changes. Terminals at Singapore, Fujairah, Rotterdam, and Houston run dedicated blending operations, and quality testing under ISO 8217 keeps these products tradable across borders. This flexibility, along with strong buyer familiarity, keeps blended grades well ahead of fuel oil sold straight from a single process unit.

Hydroprocessed Fuel Oil is projected to grow at the fastest CAGR during the forecast period, as refiners add residue desulphurisation capacity to meet low sulphur demand without relying on large distillate volumes in the blend. Newer export-oriented refineries in the Middle East and Asia were built with large residue hydrotreating units that yield consistent, low sulphur streams with stable properties. These streams reduce the compatibility and off-spec risks that sometimes affect blends, which appeals to large charterers and utilities. Capital spending on residue upgrading across both regions points to rising supply of this grade.

Production Route categories include

• Blended Fuel Oil (Dominating Segment)
• Hydroprocessed Fuel Oil (Highest CAGR Segment)
• Straight-Run Fuel Oil
• Visbroken Fuel Oil

Asia-Pacific held the largest market share in 2025, as it combines the world's busiest bunkering hub in Singapore with major refining and shipping centres in China, Japan, and South Korea. China runs a large bonded bunkering system at Zhoushan and nearby ports, while India is expanding coastal bunkering and refinery output through its state oil companies. Government backing for port infrastructure, along with Singapore's licensing and quality rules for bunker suppliers, keeps supply reliable. Japan and South Korea focus on low sulphur fuel oil and residue upgrading to serve industrial and marine users. Competition is intense, with national oil companies, global majors, and port-based blenders all bidding for term contracts with container lines and bulk operators.

Middle East and Africa is projected to grow at the fastest CAGR of about 3.7% during the forecast period, with its share rising from 16% in 2025 to 19% by 2034. The UAE's Port of Fujairah is a leading bunkering and storage hub, and port data compiled by Platts showed fuel oil exports from Fujairah averaging 438,000 barrels per day in August 2025, the highest since July 2022. Saudi Arabia is replacing liquid fuels in power generation with gas and renewables, which reduces domestic burn and shifts more fuel oil toward export and bunkering use. Across Africa, new refining capacity and fuel oil-based power plants add demand. Competition includes national oil companies, port terminal operators, and global bunker suppliers expanding storage and barge fleets.

Recent Market Developments

• In January 2025, The EU FuelEU Maritime Regulation became fully applicable on 1 January 2025. It sets yearly limits on the greenhouse gas intensity of energy used on board ships above 5,000 gross tonnes trading in EU and EEA waters, starting with a 2% cut that deepens over time. The rule pushes suppliers serving European ports to offer bio-blended and other lower-carbon fuel oil, while shipowners use banking and pooling to manage compliance.
• In April 2025, Shell completed the sale of its Singapore Energy and Chemicals Park, including the Bukom refinery, to CAPGC, a joint venture between Chandra Asri and Glencore, on 1 April 2025. The site was renamed Aster, and its product slate includes fuel oil. Shell keeps its marketing and trading role in Singapore, so the deal changes who produces fuel oil at the hub rather than who sells it to Shell customers.
• In March 2026, The IEA's 12 March 2026 Oil Market Report said tanker traffic through the Strait of Hormuz had nearly stopped after strikes on Iran on 28 February, with flows at less than 10% of pre-crisis levels. The report noted that Gulf fuel oil exports, about 270,000 barrels per day of straight-run, 420,000 of high sulphur, and 70,000 of very low sulphur fuel oil in 2025, equal 15% to 20% of global fuel oil trade and mostly serve bunker markets.
• In May 2026, ENEOS Holdings signed agreements on 14 May 2026 to acquire Chevron's 50% stake in Singapore Refining Company, a 290,000 barrels per day refinery that produces bunker fuels, together with Chevron downstream businesses in Malaysia, the Philippines, Vietnam, Indonesia, and Australia, for about USD 2.17 billion. Closing is expected in 2027 and gives a Japanese refiner a direct position in Singapore marine fuel supply.
