In Part 1 of our Gibraltar Bunkering Guide 2026 (click here to read), we explored why Gibraltar has become one of the world’s leading bunkering hubs, examining its strategic location, established maritime infrastructure and the commercial advantages that continue to attract shipowners from around the world.
In this second part, we take a closer look at one of the most important considerations for every vessel operator, bunker prices. We’ll compare Gibraltar’s bunker prices with other major international ports, explain why fuel price alone should never determine where a vessel bunkers and examine how Ship-to-Ship (STS) bunkering helps Gibraltar remain one of the most efficient bunkering locations in the world.
Record Growth Demonstrates Continued Confidence
The continued growth of Gibraltar’s bunkering sector provides compelling evidence of its importance within global shipping.
According to Government of Gibraltar statistics reported by Ship & Bunker, 599 vessels called for bunkering during May 2026, representing the highest monthly total recorded in at least fifteen years.
This followed several months of exceptionally strong bunker activity and reflected the confidence that commercial operators continue to place in Gibraltar’s marine fuel infrastructure despite ongoing geopolitical uncertainty, changing environmental regulations and fluctuating global energy markets.
Every bunker call represents a commercial decision.
Shipowners have a wide choice of bunkering locations around the world, including Rotterdam, Singapore, Fujairah, Houston, Malta and Panama. The fact that increasing numbers of operators continue choosing Gibraltar demonstrates that they see value extending far beyond the advertised fuel price.
Several factors continue driving this growth:
- Strategic geographical location
- Reliable fuel availability
- Competitive bunker pricing
- Efficient Ship-to-Ship (STS) operations
- Experienced bunker suppliers
- Comprehensive maritime services
- Strong operational reliability
The increase in bunker calls is particularly significant because operators have genuine choice. Continued growth suggests that Gibraltar’s combination of location, efficiency, service quality and operational reliability continues to outperform many competing bunker ports.
For commercial operators, reliability is every bit as important as price.
Delays of only a few hours can affect charter agreements, cargo schedules, berth availability and downstream logistics. Gibraltar’s mature bunkering market provides the consistency that voyage planners need when managing complex international shipping operations.
This is also where experienced local coordination becomes valuable. Companies such as MH Bland Port Agency help shipowners coordinate bunkering alongside launch services, customs formalities, crew changes and husbandry requirements, helping vessels complete their port calls efficiently while reducing unnecessary delays.

How Gibraltar’s Bunker Prices Compare with Other Major Ports
When planning a bunker call, fuel price is naturally one of the first factors operators consider. Marine fuel represents one of the largest operating costs for any commercial vessel, so even relatively small price differences can have a significant impact across an entire fleet.
However, experienced shipowners know that the lowest advertised bunker price does not always result in the lowest overall operating cost.
The true cost of bunkering also depends on:
- Voyage deviation
- Waiting times
- Fuel availability
- Operational efficiency
- Port congestion
- Berth availability
- Reliability of suppliers
- The ability to complete additional services during the same call
Gibraltar is regularly compared with several of the world’s largest bunkering locations.
Rotterdam remains Europe’s largest bunker market, serving thousands of vessels operating throughout Northern Europe.
Singapore is widely recognised as the world’s busiest bunkering hub, supporting vessels trading throughout Asia and the Pacific.
Fujairah has become a major fuel supply centre for vessels operating between Asia, the Middle East and Europe.
Houston is a key bunkering location for operators trading throughout the Americas.
Each of these ports offers its own advantages. However, Gibraltar’s unique location at the entrance to the Mediterranean means many vessels can bunker without making significant deviations from their planned voyage.
The table below provides a snapshot comparison of bunker prices across several leading international bunkering hubs.
| Port | VLSFO (USD/MT) | HSFO (USD/MT) | MGO (USD/MT) | Key Advantage |
| Gibraltar | 643 | 543 | 1,116 | Strategic location with minimal voyage deviation |
| Rotterdam | 592 | 536 | 874 | Europe’s largest bunker market |
| Singapore | 707 | 599 | 1,039 | World’s largest bunkering hub |
| Fujairah | 1,104 | 622 | 1,111 | Key Middle East fuel supply hub |
| Houston | 645 | 507 | 1,011 | Major Americas bunkering location |

Did You Know?
A bunker port with slightly higher fuel prices can still represent the lower overall operating cost if vessels avoid significant voyage deviation, reduce waiting time and complete multiple operational services during the same port call.
It is also worth remembering that bunker prices fluctuate daily in response to changes in crude oil markets, refinery production, regional demand and geopolitical events. Professional operators therefore evaluate bunker prices alongside operational efficiency, scheduling flexibility and total voyage costs.
Why Total Voyage Cost Matters More Than Fuel Price
One of the biggest misconceptions in the shipping industry is that the cheapest bunker fuel automatically represents the best commercial decision.
In reality, professional voyage planners evaluate the total cost of bunkering, rather than simply comparing the headline fuel price.
Imagine a vessel saves just USD 5 per metric tonne by selecting another bunker port.
Initially, this appears to be a worthwhile saving.
However, if reaching that port requires additional sailing time, extra fuel consumption, longer waiting periods or causes delays to cargo operations, those savings can quickly disappear.
Operators therefore consider a much broader range of factors:
- Fuel price
- Voyage deviation
- Waiting times
- Anchorage availability
- Port congestion
- Fuel consumed reaching the port
- Berth availability
- Reliability of bunker suppliers
- Ability to complete multiple services during one call
For example, delaying a vessel by several hours may affect subsequent berthing windows, crew changes, cargo loading schedules and charter commitments. These indirect costs often outweigh relatively small differences in bunker pricing.
Because Gibraltar lies directly on established international shipping routes, vessels can frequently bunker with minimal deviation, reducing fuel consumption while maintaining schedule reliability.
This combination of competitive pricing and operational efficiency continues to make bunkering in Gibraltar an attractive commercial decision.
Experienced port agents such as MH Bland Port Agency further improve efficiency by coordinating multiple services during the same port call, allowing operators to maximise the value of every visit to Gibraltar.
Why Gibraltar Continues to Outperform Other Bunkering Ports
While many ports compete primarily on bunker price, Gibraltar competes on overall operational efficiency.
Its strategic location allows vessels to remain close to established trade routes while benefiting from an experienced maritime community capable of supporting virtually every operational requirement.
Rather than making separate calls for fuel, crew changes, husbandry or technical attendance, operators can frequently complete all of these services during one coordinated visit.
This integrated approach reduces operational complexity while improving vessel utilisation.
For many shipping companies, that commercial efficiency represents a greater saving than securing marginally lower fuel prices elsewhere.
Ship-to-Ship (STS) Bunkering in Gibraltar
One of Gibraltar’s greatest competitive strengths is its well-established Ship-to-Ship (STS) bunkering capability.
Rather than requiring vessels to berth alongside a terminal, Gibraltar allows marine fuel to be delivered directly from licensed bunker barges to vessels anchored offshore.
Ship-to-Ship bunkering provides greater operational flexibility while helping vessels minimise waiting times and avoid unnecessary berth congestion.
This method has become the preferred fuel delivery solution for many commercial operators because it enables vessels to receive fuel safely, efficiently and with minimal disruption to their voyage.
The benefits of STS bunkering include:
- Faster bunker operations
- Reduced waiting times
- Greater scheduling flexibility
- Lower operational costs
- Efficient fuel transfer
- Minimal interruption to voyage plans
Gibraltar’s STS operations are supported by experienced bunker suppliers operating under strict operational procedures and internationally recognised safety standards.
For operators, this provides confidence that bunker operations can be completed efficiently while maintaining the highest levels of safety and environmental protection.
As international shipping continues to focus on efficiency and sustainability, the ability to bunker quickly while remaining close to established trade routes will remain one of Gibraltar’s greatest competitive advantages.
Marine Fuels Available in Gibraltar
As international shipping continues to evolve, so too do the fuel requirements of commercial vessels.
Environmental legislation, changing emission standards and the industry’s transition towards lower-carbon operations mean shipowners require access to a wide range of compliant marine fuels.
Gibraltar has developed a mature and reliable bunker market capable of supporting the needs of modern commercial shipping.
Very Low Sulphur Fuel Oil (VLSFO)
Following the implementation of the IMO 2020 sulphur regulations, VLSFO became the standard marine fuel used by most commercial vessels. Gibraltar’s bunker suppliers provide reliable access to VLSFO, allowing vessels to comply with international emissions regulations while maintaining operational efficiency.
Marine Gas Oil (MGO)
Marine Gas Oil is commonly used by vessels operating within Emission Control Areas, during port operations and by specialist offshore vessels requiring cleaner-burning fuel with lower sulphur content.
High Sulphur Fuel Oil (HSFO)
Although its use has reduced since IMO 2020, HSFO remains an important fuel option for vessels equipped with approved exhaust gas cleaning systems (scrubbers). These vessels continue benefiting from HSFO’s competitive pricing while remaining compliant with emissions legislation.
Biofuel Blends
As shipping moves towards decarbonisation, biofuel blends are becoming increasingly important. Depending on supplier availability, vessels calling at Gibraltar may be able to source biofuel blends that help reduce lifecycle greenhouse gas emissions without requiring major engine modifications.
Gibraltar’s ability to adapt to changing fuel requirements demonstrates why it continues to be recognised as one of Europe’s leading bunkering locations.
