The $40-A-Barrel Cost Most Oil Consumers Never See

When Americans think about the price of oil, they usually focus on the number quoted every day in financial markets. If Brent crude is trading above $100 a barrel or West Texas Intermediate is near $100, those numbers become shorthand for whether oil is expensive or cheap. But that market price is only part of what ultimately determines the cost of getting crude oil to a refinery.

But transportation has become a cost that has become impossible to ignore. Reuters recently reported that shipping roughly 2 million barrels of crude from the United States to Japan aboard a very large crude carrier could cost about $81 million. That works out to approximately $40.50 for every barrel on the ship, compared with roughly $9 million for a similar voyage a year earlier. At current rates, freight alone can represent a huge addition to the underlying value of the oil.

For most consumers, tanker rates are an obscure corner of the energy market. Yet the extraordinary increase in shipping costs is helping reshape global oil flows and adding another layer of expense to a market already dealing with elevated crude prices, refinery constraints, and geopolitical risk.

A barrel of crude oil is only useful if it can get from where it is produced to a refinery capable of processing it. The gasoline, diesel, jet fuel, and other products produced there then have to make another journey to the markets where they are consumed.

In normal times, ocean transportation is inexpensive enough on a per-barrel basis that few consumers ever think about it. The largest crude carriers can move roughly 2 million barrels at a time, creating enormous economies of scale and allowing oil to travel halfway around the world without freight overwhelming the value of the cargo.

That system becomes far more expensive when tankers are scarce or voyages become riskier and longer. The Energy Information Administration says tanker rates reached record levels in September as insurance costs increased and ships took longer routes to avoid conflict zones. Longer voyages also tie vessels up for more days, effectively reducing the available tanker fleet even if the physical number of ships has not changed.

The distinction between the quoted price of crude and its delivered cost is therefore crucial. A refinery does not care only what a barrel costs at an export terminal. Freight, insurance, delays, and other transportation costs all become part of the economics by the time that barrel arrives.
