The rising cost of gasoline has become a hot-button issue, with prices expected to hit 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. It's a complex web of global markets, domestic policies, and infrastructure challenges.
The Breakdown of Gas Prices
When you fill up your tank, the price you pay is a combination of four key elements: the cost of crude oil, refining, distribution and marketing, and taxes. In January 2026, crude oil accounted for over half of the pump price, with refining, distribution, and taxes making up the rest.
The price of crude oil is the biggest driver, and it's largely influenced by global demand and supply. Typically, big swings in crude prices are due to shifts in demand and expectations, but the ongoing war in Iran has created a classic supply shock, disrupting shipping and taking millions of barrels off the market.
Refining and the California Conundrum
Refining is the process of turning crude oil into gasoline, and it's not a one-size-fits-all operation. The U.S. has different types of gasoline, including reformulated gasoline, which is required in urban areas to reduce smog. California, in particular, has an even stricter formulation, and its geographic isolation means it relies on its own refineries.
California's gasoline prices have always been higher than the national average, and this gap has widened since a refinery fire in 2015. This 'mystery gasoline surcharge' is estimated to have cost California drivers $59 billion from 2015 to 2024. The exact beneficiaries of this surcharge are unclear, but it could be gas stations or refineries, indicating a lack of competition in the state.
Distribution and Marketing: Getting Gas to Your Car
The distribution and marketing category covers the costs of getting gasoline from the refinery to your tank. This involves pipelines, ships, rails, and trucks, and at the retail end, key factors include station rent, labor, credit card fees, and franchise fees. Gas station operators often net only a few cents per gallon, which is why many stations are convenience stores with pumps.
Gas Tax Holidays: A Partial Solution
When gas prices rise, politicians often propose suspending state gas taxes. While this does reduce prices, it's not as significant as hoped. Research shows that consumers only get about 79% of the reduction in gas taxes, with oil companies and retailers keeping the rest. Additionally, gas tax holidays reduce funding for road and bridge maintenance, pushing these costs onto future drivers and taxpayers.
The Jones Act: A Small Impact, Big Implications
The 1920 Jones Act is a federal law that restricts cargo movement between U.S. ports to U.S.-built, -registered, and -crewed vessels. This law limits the number of oil tankers that can transport refined fuels, leading to some U.S. gasoline being exported while the Northeast imports fuel. Economists estimate that the Jones Act raises East Coast gasoline prices by about a penny and a half per gallon, costing drivers $770 million annually.
The Bigger Picture
The price at the pump is a reflection of global crude prices and a stack of domestic costs. Tax holidays and Jones Act waivers provide temporary relief, but the real solution lies in more efficient vehicles or those that don't rely on gasoline. In the meantime, it's important to understand what that $4.30 is really buying and the complex web of factors that contribute to it.
