The renewed surge in oil transportation costs is exposing a less visible source of inflation in the global economy: the expense of moving energy from producers to consumers. While rising crude prices usually attract the most attention, the cost of shipping oil can independently increase the price of fuel, industrial production and everyday goods. As geopolitical tensions disrupt maritime routes and reduce the availability of tankers, the transportation system is becoming an additional source of pressure on businesses and households.
The scale of the increase is illustrated by the planned voyage of the supertanker Esteem Explorer from the United States to Japan. Carrying approximately two million barrels of crude oil, the journey is expected to cost $81 million in late November 2026, compared with an average of $9.1 million for the same journey a year earlier. At approximately $40.50 per barrel, the freight charge demonstrates how transportation can become a substantial component of the delivered cost of energy.
The immediate concern is not simply that shipping companies are charging more. It is that higher freight expenses are emerging alongside elevated oil prices, geopolitical uncertainty and inflationary pressures in major economies. The resulting combination makes it more difficult for central banks to control inflation without weakening economic activity.
Geopolitical Risk Is Reshaping Shipping Economics
Attacks on vessels associated with the conflicts involving the United States, Israel and Iran, as well as the continuing Russia-Ukraine war, have increased the risks associated with transporting oil. Shipping companies must consider the possibility of direct attacks, higher insurance premiums, route restrictions and delays. Even when a vessel completes its journey safely, the cost of operating in a dangerous environment can rise substantially.
The Strait of Hormuz and the Red Sea have become particularly important sources of uncertainty because of their position within international energy transportation networks. When ships avoid dangerous waters, alternative routes can increase journey times and fuel consumption. Longer voyages also mean that vessels remain unavailable for other cargoes for extended periods, reducing effective shipping capacity even when the total number of tankers has not changed.
Some operators have adopted ship-to-ship transfers to reduce exposure at individual locations. Such arrangements can spread risk, but they require additional vessels, coordination and time. When these practices become widespread, they can absorb capacity that would otherwise be available to transport other cargoes.
The shortage of very large crude carriers has consequently increased demand for smaller vessels. Freight rates for certain routes involving Suezmax and Aframax tankers have risen sharply since the conflict with Iran began in February. In some cases, rates have quadrupled, intensifying pressure on companies that must secure transportation shortly before loading.
These developments demonstrate that energy supply cannot be assessed solely by counting barrels produced. Oil must also be transported through a functioning network of vessels, ports, pipelines and insurance arrangements. A disruption at any of these stages can raise the final price even when the underlying commodity remains available.
Why Shipping Costs Reach Consumers
The effects of expensive transportation extend well beyond the oil industry. Refineries depend on crude supplies to produce petrol, diesel and aviation fuel. Diesel powers trucks, agricultural machinery and much of the equipment used to move goods between factories, warehouses and shops. Higher fuel costs can therefore affect food distribution, construction materials, manufacturing and retail logistics.
The impact is not immediate or uniform. Companies operating under long-term transport contracts may be temporarily protected from increases in spot freight rates. Others purchase shipping capacity closer to the loading date and face faster adjustments. Businesses may initially absorb some of the additional expense to protect market share, but prolonged cost increases can eventually lead to higher prices for customers.
For the United States, an increase of $10 per barrel in shipping costs has been estimated to add approximately 23 cents per gallon to petrol prices. On that basis, the freight expense associated with the planned Esteem Explorer voyage could translate into at least 80 cents per gallon in additional petrol costs compared with the previous year, assuming the stated shipping-cost relationship holds. This is an illustrative calculation rather than a prediction of the exact price consumers will pay, since refining margins, taxes, distribution costs and retail competition also influence the final price.
The consequences may be more pronounced in countries that rely heavily on imported energy. India, Indonesia and the Philippines must manage international freight expenses alongside the cost of crude itself. Higher import bills can place pressure on national currencies, increase subsidy requirements or force governments to make difficult decisions about how much of the increase should be passed on to consumers.
Food prices may respond with a delay. Farmers face higher costs for diesel, fertilisers and transportation, while food processors and retailers must pay more to move products through supply chains. These expenses can accumulate at several stages before reaching supermarket shelves. Consequently, inflation may remain elevated even if crude prices begin to stabilise.
A Windfall for Tanker Owners, a Burden for Importers
The disruption has created sharply different outcomes across the energy industry. Tanker owners can benefit from unusually high freight rates, particularly when vessels are available for short-term chartering. Earnings on some voyages from the Persian Gulf through the Strait of Hormuz to Asia have reached approximately $1.3 million per vessel per day, compared with an average of $55,000 in 2025.
Such returns reflect a combination of restricted capacity, higher perceived risk and strong demand for transportation. However, exceptional earnings should not automatically be interpreted as a permanent improvement in the industry's economics. Shipping markets are cyclical, and high rates can encourage operators to deploy more vessels or invest in additional capacity. If oil demand weakens or the supply of available ships improves, freight rates could fall rapidly.
The timing of contracts is therefore important. Companies that have secured long-term agreements at lower prices may be protected from the current increase, while those relying on the spot market face greater exposure. Yet long-term contracts can also become expensive for shipping buyers if market rates decline, illustrating the trade-off between price certainty and flexibility.
For refiners, the situation is more difficult. They may be unable to pass every increase in crude and transportation expenses on to consumers, particularly when demand is weak or competition limits pricing power. The International Energy Agency has warned that soaring tanker rates are already squeezing the profitability of Asian refiners, showing how transportation costs can weaken businesses even when the wider oil market remains active.
Inflation Creates a Monetary Policy Dilemma
Higher shipping costs complicate the task facing central banks. If energy transportation becomes more expensive, headline inflation may rise even when demand is not accelerating. Policymakers must then determine whether the increase is a temporary supply shock or a sign that inflationary pressures are spreading through the wider economy.
Raising interest rates cannot reopen a disrupted shipping route or immediately increase the supply of tankers. However, monetary tightening may be used to prevent higher energy costs from feeding into wages, services and longer-term inflation expectations. The danger is that tighter financial conditions can also weaken household spending and business investment.
Governments face a similar balancing act. Temporary assistance to vulnerable households can soften the immediate impact, but broad fuel subsidies may strain public finances and reduce incentives to conserve energy. Diversifying suppliers, improving strategic reserves and strengthening alternative transportation routes can improve resilience, although these measures require time and investment.
The persistence of the current shock will depend on security conditions, the availability of vessels, oil demand and the ability of producers to redirect supplies. A reduction in geopolitical risk could bring freight rates down quickly, but prolonged disruption could leave transportation expenses embedded in prices across the economy.
The central economic issue is that global inflation is increasingly influenced by the reliability of physical supply chains as well as by monetary conditions. When moving a barrel of oil becomes dramatically more expensive, the resulting pressure can reach households far removed from the original conflict. Restoring stability therefore requires not only adequate energy production but also safe, affordable and dependable transportation.
