The rising cost of gasoline has become a hot-button issue, with prices expected to reach an all-time high in April 2026. As an energy economist, I often find myself explaining the factors that contribute to these price hikes and the potential solutions being proposed. Let's dive into this complex topic and explore the various elements that make up the price of a gallon of gas, and the implications of each.
The Breakdown
The price of gasoline can be broken down into four main components: the cost of crude oil, refining, distribution and marketing, and taxes. Each of these factors plays a significant role in the final price we see at the pump.
Crude Oil: The Dominant Factor
Crude oil, the raw material used to produce gasoline, accounts for the largest portion of the pump price, typically around 51% on average. However, this percentage can fluctuate, especially during supply shocks like the ongoing war in Iran. In such cases, crude oil prices can spike, driving over 60% of the overall gasoline price.
What makes this particularly fascinating is the global nature of the oil market. Big swings in crude prices are often driven by shifts in global demand and expectations, rather than supply disruptions. This means that events happening on the other side of the world can have a direct impact on the price of gasoline in the U.S.
Refining: Turning Crude into Gasoline
Refining is the process of turning crude oil into gasoline, and it accounts for roughly 20% of the pump price. However, the U.S. doesn't have a single gasoline market; there are different blends required in different regions, such as the cleaner-burning reformulated gasoline used in urban areas across 17 states and the District of Columbia.
California, with its stricter environmental rules, uses an even more specialized formulation. This geographic isolation and the lack of pipelines bringing gasoline from other refining regions contribute to California's higher gasoline prices. A 'mystery gasoline surcharge' has been attributed to the reduced competition between refineries and gas stations in the state, costing drivers an estimated $59 billion from 2015 to 2024.
Distribution and Marketing: Getting Gasoline to the Pump
The distribution and marketing category covers the costs of getting gasoline from the refinery to your tank. This includes transportation by pipeline, ship, rail, and truck, as well as the costs of wholesale terminals, local delivery trucks, and service stations. Additionally, credit card fees, franchise fees, and rent and labor costs for the gas stations themselves are all part of this category.
An interesting observation is that gas station operators often net only a few cents per gallon on fuel itself, which is why many gas stations are primarily convenience stores with pumps.
Taxes: The Controversial Component
Taxes on gasoline are a controversial topic. The federal government charges 18.4 cents per gallon for gasoline and 24.3 cents for diesel, while state taxes vary widely, from 70.9 cents in California to 8.95 cents in Alaska. When gas prices rise, politicians often propose suspending state gas taxes, but this only reduces prices by about 79%, with oil companies and fuel retailers keeping the rest.
The implications of gas tax holidays are far-reaching. They reduce funding for road and bridge maintenance, pushing these costs onto future drivers and taxpayers. Additionally, fuel taxes are meant to cover some of the costs that driving imposes on society, such as carbon emissions, pollution, congestion, and crashes. However, U.S. fuel tax levels are already far below the true cost to society, so removing this tax effectively shifts these costs onto others.
Deeper Analysis
The Jones Act, a federal law requiring cargo moving between U.S. ports to be transported on U.S.-built, -registered, and -crewed vessels, is another factor impacting gasoline prices. With only 54 oil tankers meeting these requirements out of the world's 7,500, the law effectively limits the transportation of gasoline between U.S. ports, leading to higher prices, especially on the East Coast. Economists estimate that the Jones Act raises East Coast gasoline prices by about a penny and a half per gallon on average.
In light of the war in Iran and its impact on gas prices, the Trump administration has temporarily suspended the Jones Act requirements, a move more commonly seen during natural disasters like hurricanes. This suspension is expected to trim pennies off the price of gasoline, but a permanent repeal could have more fundamental impacts, potentially reducing the need for rail and truck transport of goods, which could lower costs, emissions, and infrastructure damage.
Conclusion
The price of gasoline is a complex issue, influenced by a multitude of factors, from global crude oil prices to domestic refining, distribution, and marketing costs, as well as taxes. While temporary measures like tax holidays and Jones Act waivers can provide some relief, the best long-term solution lies in more efficient vehicles or those that don't burn gasoline at all. As an economist, my role is to provide clarity on these issues, helping consumers understand what their money is buying and the broader implications of these economic decisions.
