Donald Trump promised on October 10, 2024, to cut gas prices by 50% within 12 months of taking office. “Your gasoline for your car is going to be 50% cheaper,” he said. That would have meant gas prices at $1.56 per gallon by April 2026 if his promise held true—a figure that now looks impossible to achieve.
The national average as of April 2026 stands at $4.06 to $4.08 per gallon, representing a 28% increase from when Trump took office on January 20, 2025, when the average sat at $3.12 per gallon. Pump prices are determined by several interconnected factors, none of which a president controls directly. Crude oil prices, refining capacity, distribution costs, taxes, and global geopolitical events all play roles in what Americans pay at the pump. Understanding these drivers reveals why grand promises about halving gas prices are difficult to keep—and why prices have actually moved in the opposite direction during Trump’s first year in office.
When trump took the oath of office in January 2025, his campaign pledge about gas prices seemed achievable to some supporters. Gas sat at a manageable $3.12 per gallon nationally. Under Trump’s promise, drivers would be paying $1.56 per gallon by now. Instead, the national average has climbed above $4.00 per gallon for the first time since August 2022, marking the first time in roughly four years that gas exceeded that threshold.
For a family filling up a 15-gallon tank, the difference between Trump’s promised $23.40 and today’s $60-$61 reality is striking. The gap between what was promised and what happened reflects the limits of executive power over commodity markets. While a president can influence energy policy through drilling permits, strategic petroleum reserve releases, and trade negotiations, crude oil prices are ultimately set by global supply and demand dynamics. When prices spike due to international conflicts or production disruptions, no domestic policy change can instantly reverse the trend. The Trump administration’s increasingly tense relations with Iran have actually contributed to the current spike, as traders worry about potential disruptions to Middle Eastern oil supplies flowing through the Strait of Hormuz.
The Current Gas Price Crisis in April 2026
The jump to over $4.00 per gallon represents a significant shift that affects household budgets across the country. The increase happened suddenly in early April, with prices rising $1.08 in a single month. This is not a gradual creep but a sharp spike tied to specific geopolitical events and supply concerns.

The Breakdown of What Actually Drives Pump Prices
Crude oil accounts for approximately 51% of the price at the pump, making it the single largest cost component. When crude prices spike due to geopolitical tensions, supply disruptions, or speculation, pump prices follow within days. The current spike is linked to military operations in the Middle East and concerns about the Strait of Hormuz, through which roughly 20% of the world’s oil passes. If conflict escalates or closes this shipping lane, crude oil prices could spike further, pushing gas prices even higher regardless of what policies Washington implements. Refining costs make up roughly 20% of the gas price.
This is the step where crude oil gets converted into usable gasoline at refineries. Seasonal factors significantly affect refining costs, particularly the transition to summer-blend gasoline in February and March each year. Summer blends are more expensive to produce due to stricter environmental regulations on emissions, which is one reason drivers often see a price jump in spring. Additionally, refining capacity in the United States has declined over the past two decades as older refineries close. With fewer refineries to process crude oil into gas, any supply disruption or unexpected maintenance shutdown can tighten the market and push prices higher.
Distribution, Marketing, and the Path from Refinery to Pump
Once refined, gasoline must be transported to regional distribution centers and then trucked to individual gas stations. Distribution and marketing account for roughly 11% of the price at the pump. This includes the cost of running pipelines, distribution networks, and paying station operators. In rural areas or regions far from major refineries, these distribution costs can be higher, which is why gas in remote locations sometimes exceeds that of nearby urban areas. Truck driver wages, fuel for delivery trucks, and labor costs at stations all feed into this component.
Marketing and branding also factor into the final price. Major branded stations like Shell, Chevron, or Exxon sometimes charge a premium compared to unbranded or independent stations, even when the gas comes from the same source. Convenience store sales and car wash bundling also affect station profitability and pricing. A $4.00 gallon of gas at a branded station with a convenience store might be sold for $3.85 just down the road at an independent operator with minimal overhead. Consumers who shop around and fill up at off-brand stations rather than premium-branded ones can save 10 to 15 cents per gallon—modest in absolute terms, but meaningful over time.
Taxes: The Hidden Cost at Every Pump
Taxes represent a significant but often invisible component of what Americans pay at the pump. As of January 2026, the average combined state, federal, and local tax on gasoline is 33.55 cents per gallon. This means that roughly 8 to 9 cents of every dollar you spend at the pump goes to taxes. Federal excise tax on gasoline is 18.4 cents per gallon, unchanged since 1993. State taxes vary dramatically: California charges 68.27 cents per gallon in combined excise and sales taxes, while Alaska charges just 14.27 cents.
These tax differences compound the regional variation in prices. Importantly, taxes are largely outside presidential control without congressional action. While Trump could theoretically push for a federal fuel tax cut, doing so would require Congress to approve it, and such cuts would impact highway infrastructure funding. The structure of fuel taxes—some states tax the volume, others tax the percentage—means that when crude oil prices spike, the tax burden also increases in states with percentage-based taxes. A driver in a high-tax state like California faces a compounded problem: not only does crude oil spike affect them more due to regulatory factors, but their taxes also increase as a percentage of a higher price.
How Geopolitical Tensions Drive Prices at the Pump
The current spike in gas prices in April 2026 is directly linked to Trump administration military operations and tensions with Iran. When traders worry about potential disruptions to oil shipments through the Strait of Hormuz—the critical chokepoint through which roughly 20% of global oil passes—crude oil prices surge. A single threat of conflict or minor incident can send crude prices up $5 to $10 per barrel within hours, which translates to 10 to 25 cents per gallon at the pump within days.
This geopolitical dynamic undermines the narrative that any administration can simply “cut” gas prices through policy alone. Presidents inherit a world market with dozens of producers and consumers negotiating on the global stage. Decisions to escalate or de-escalate international conflicts have immediate impacts on energy markets that dwarf any domestic drilling permit or refinery approval.
Looking Ahead—What Gas Prices Reveal About Executive Promises
Gas prices have proven difficult for many administrations to manage. When gas spiked under President Biden in 2022, the administration released oil from the Strategic Petroleum Reserve, but prices still remained elevated due to global supply constraints and the aftermath of Russia’s invasion of Ukraine. When gas fell in late 2024, the Trump campaign credited this to the election outcome alone—ignoring that global supply conditions had improved and demand had softened.
Both parties have a history of claiming credit for price drops they didn’t cause and deflecting blame for increases beyond their control. The real lesson from Trump’s 50% price-cut promise is that commodity prices respond to global forces, not political pledges. Crude oil markets care about Iranian sanctions enforcement, OPEC production decisions, refinery maintenance schedules, and shipping routes—not campaign promises. As gas prices remain elevated into mid-2026, voters should recognize that the gap between what’s promised and what’s possible reflects the actual structure of global energy markets, not the competence or incompetence of any single administration.
Conclusion
Donald Trump’s promise to cut gas prices by 50% has not materialized. Instead, prices have increased by 28% since he took office, reaching $4.06 to $4.08 per gallon nationally in April 2026—well above the $1.56 per gallon his promise would have required. Understanding why prices have moved in the opposite direction requires looking at the fundamental drivers of pump prices: crude oil (51%), refining costs (20%), distribution (11%), and taxes (33.55 cents per gallon).
Consumers facing $4-plus gas prices have little recourse except to recognize that pump prices reflect global supply and demand, not campaign rhetoric. Regional variations from $3.27 in Oklahoma to $5.89 in California show how local policy, refining infrastructure, and geopolitical factors create different realities. Moving forward, voters should evaluate energy policy based on what presidents can actually influence—domestic drilling, refining capacity, and international relations—rather than promises to cut commodity prices in half within a year.
