Oil Shipping Costs Spike, Lifting Prices from Pump to Grocery

The main driver was a surge in risk and vessel scarcity. Attacks linked to the U.S.-Iran war and the Russia-Ukraine war raised freight and insurance costs. Ships also took longer routes to reduce danger, keeping tankers unavailable for other cargoes. That combination made each voyage much more expensive.

The Esteem Explorer’s late-November trip from the United States to Japan illustrates the change. Carrying about 2 million barrels, it is expected to cost $81 million. The same voyage averaged $9.1 million last year. Its shipping cost therefore reaches $40.50 per barrel, compared with roughly $4.55 previously.

Ship-to-ship transfers added another pressure. Saudi-oil shippers used more vessels to reduce risks to individual ships, lowering overall availability. Freight rates for some smaller tankers also quadrupled after the Iran war began. Costs could fall quickly if crude supply exceeds demand, but they may remain strong while demand is higher than supply.

A freight rate is the price for moving cargo by sea. For crude oil, it covers the tanker’s transportation service and reflects factors such as vessel availability, voyage distance, fuel, and perceived risk. It matters because shipping is part of the delivered cost paid by refiners and other oil buyers.

In the article, freight rates account for more than 40% of the U.S. oil price, based on a Wednesday price near $95 per barrel. In 2025, freight represented about 7% on average. The jump reflects attacks, higher insurance premiums, longer sailing routes, and tankers being tied up for more time.

When shipping absorbs a larger share of oil’s value, imported crude becomes more expensive even before refining. That pressure reaches gasoline, diesel, and jet fuel. It also affects goods moved by trucks, ships, and planes. If crude supply loosens, tanker rates may fall quickly, according to the article.

The Esteem Explorer’s shipping cost is $40.50 for each barrel of crude. The same U.S.-Japan journey averaged $9.1 million last year, compared with $81 million now. Because the tanker carries about 2 million barrels, the current voyage cost works out to roughly nine times last year’s per-barrel rate.

The gasoline effect is also striking. Energy economist Kenneth Medlock said every $10 increase in shipping costs adds about 23 cents per gallon to gasoline. Reuters calculated that the Esteem Explorer’s shipping cost represents at least 80 cents more per gallon than last year. This is a transport-cost effect, before considering other changes in oil prices or refining costs.

The pressure spreads beyond motorists. Refiners turn crude into gasoline, diesel, and jet fuel. Those fuels move food, retail products, construction materials, and farm supplies. If dangerous routes and limited tankers keep freight rates high, imported-oil economies may face continued inflation. Rates could ease when crude supply becomes less tight.

Attacks make operators avoid exposed waters or demand higher insurance premiums before sailing. Longer routes take more days, so one tanker completes fewer trips during a given period. The vessel is effectively removed from the available fleet for longer, even though it is still carrying cargo.

Ship-to-ship transfers create another drain on capacity. The article says shippers moving Saudi oil are using more vessels than before to reduce the risk faced by individual ships. Cargo changes hands at sea instead of moving through one continuous voyage. More tankers are therefore needed for the same oil movement, while each remains tied up longer.

These effects reduce the number of ships available on the spot market. The resulting shortage of very large crude carriers lifted prices for smaller vessels, too. Suezmax rates for some routes and Aframax rates on another route quadrupled since the Iran war began. Higher rates may persist while crude demand exceeds supply.

Import-dependent countries have fewer domestic sources to cushion a jump in ocean transport costs. When they buy crude from distant suppliers, the delivered price includes tanker freight and insurance. A sharp rise in either charge makes the imported barrel more expensive before local refining and distribution.

The article specifically identifies India, the Philippines, and Indonesia as countries bearing the brunt of higher costs. Rates for moving oil from Middle Eastern routes toward Asia reached about $34 per barrel this week. Asian refiners are already seeing their profits squeezed because transporting the crude consumes more of the value they receive from selling fuel.

The effects spread through their economies. Refiners produce gasoline, diesel, and jet fuel, which support transport, farming, aviation, and the movement of goods. Higher fuel costs can therefore raise prices at stores and food markets. The pressure may ease if crude supply loosens, but the article says tanker rates remain strong while demand exceeds supply.

When the Strait of Hormuz or the Red Sea becomes more dangerous, traders and ship operators can adjust how cargo moves. The article says ships are sailing longer routes to reduce attack risk. That choice may avoid a threatened area, but it uses more time and vessels. The article does not identify specific replacement waterways.

Another arrangement is ship-to-ship transfer. Shippers moving Saudi oil use more vessels than before, transferring cargo between ships to reduce the risk to individual vessels. This spreads the journey across multiple tankers. It can protect a particular ship from carrying the entire cargo through a risky stretch, but it reduces fleet availability and increases costs.

These alternatives are not free solutions. Longer voyages tie up ships, while transfers add handling and require extra vessels. The article links both effects to record freight rates and higher insurance costs. If traders can safely return to shorter routes, capacity could improve. Otherwise, shipping expenses may remain elevated while attacks continue.

Crude oil is refined by separating and processing its components into usable fuels. The article identifies gasoline for cars, diesel for semi-trucks and farm equipment, and jet fuel for airplanes. This transformation makes crude useful for transport and other activities, although the article does not describe the refinery steps in detail.

The connection to prices is straightforward. Trucks carry food and retail goods, farm equipment supports agriculture, and airplanes move people and cargo. Construction materials also depend on transport. When crude becomes more expensive to ship, refiners face higher input and delivery costs. Those costs can work through fuel prices and then through the prices of transported goods.

The article estimates that every $10 increase in shipping costs adds about 23 cents per gallon to gasoline. It also says the Esteem Explorer’s current voyage implies at least 80 cents more per gallon than last year. If freight rates stay high, import-dependent economies may experience broader inflation.
