The increase in maritime oil transportation costs has become one of the key factors influencing energy prices in global markets. The cost of transporting a 2 million barrel shipment of crude oil from the United States to Japan has reached approximately $81 million, which represents a ninefold increase compared to the $9 million cost for the same route last year.
Impact of High Transportation Costs on Global Energy Trade
The rising costs of oil tanker transportation, including insurance costs, rerouting of ships, and effective capacity limitations of the tanker fleet, have led to an increase in the final delivery cost of oil and also made global energy trade more challenging. For example, the $81 million cost of transporting the shipment from the United States to Japan translates to about $40.5 in transportation costs per barrel of oil, which can affect the economic viability of oil exports and imports.
Factors Contributing to the Increase in Maritime Transportation Costs
Increased geopolitical tensions, attacks on ships, and rerouting of tankers are among the main factors driving up maritime transportation costs. The necessity for ships to avoid high-risk areas increases the duration of each voyage, leading to a reduction in the number of vessels available for transporting new shipments.
Increased demand for tankers on several trade routes has intensified competition among buyers for chartering ships. The daily earnings of some supertankers have recently exceeded one million dollars, compared to $55,000 per day in 2025, indicating significant changes.
Additionally, the accumulation of heavy oil in the Americas due to high transportation costs has created challenges for refineries in Asia and Europe. These refineries are facing higher costs to secure the necessary feedstock, and some buyers are seeking to source shipments from the Middle East or Latin America instead of purchasing oil from the United States.
Ultimately, maritime transportation costs have become an independent factor in determining the final price of oil, and disruptions in this part of the supply chain can lead to oil accumulation in certain areas and increased supply costs in others.
