Why Are Diesel Prices Rising Faster Than Gasoline?
Diesel fuel, essential for trucks, construction equipment, and agricultural operations, has experienced steeper price increases than regular gasoline. The 50.2% national increase for diesel far outpaces the 33–38% gasoline increase, and in some regions, the gap widens considerably. Arizona’s 68.8% diesel increase means a commercial trucking company that paid $50,000 monthly for fuel costs in April 2025 could be paying roughly $84,400 by April 2026—a difference of $34,400 per month. This divergence matters because diesel price increases ripple through the entire economy.
Trucking companies pass higher costs to retailers, which pass them to consumers. food prices, shipping costs, and construction expenses all rise in response to diesel inflation. The diesel-specific surge is largely driven by the same Middle East disruption affecting crude oil supplies, but diesel markets are often tighter than gasoline markets, with fewer strategic reserves and less production flexibility, making them more vulnerable to supply shocks.
What Is Actually Causing These Price Spikes?
The primary driver of the significant gas and diesel price increases since March 2026 is the military conflict in the Middle East, specifically disruptions to the Strait of Hormuz. This critical waterway is one of the world’s most important oil chokepoints—roughly 21% of global petroleum passes through it. When the strait faces closure or threat of closure due to military action, crude oil markets react immediately, and those costs translate to higher pump prices within days.
The timing aligns precisely with the observed spike. Earlier projections from the EIA expected more stable prices throughout 2026, but the geopolitical crisis was not anticipated when those forecasts were made. This illustrates an important tradeoff in relying on government data: while EIA provides the most reliable baseline information available, it cannot predict unpredictable events. Consumers, businesses, and policymakers must account for this uncertainty when planning budgets or making claims about price trends without acknowledging the external factors driving them.

Why Cherry-Picking Time Periods Distorts the Real Picture
When Trump claims a 70% increase “in one year,” the specificity of the timeframe matters. A year-over-year comparison from April 2025 to April 2026 does show substantial increases, but different comparison periods yield different results. If measured from the lowest prices in late 2023 or early 2024, percentage increases would be even steeper. Conversely, if measured over longer periods like three years, the annual increase might appear smaller when averaged.
This practice—selecting the time period that makes a number look worse—is a common analytical pitfall that affects political rhetoric across the spectrum. A genuine 33–38% increase in gasoline prices is concerning and consequential for household budgets without needing to inflate it to 70%. The danger is that when claims are overstated, they invite credible fact-checking that can undermine legitimate criticism about actual price increases. Policymakers and political figures lose credibility when their numbers don’t match official data, even when the underlying issue (rising fuel costs) is real.
Regional Variation—Not All Gas Prices Behave the Same Way
Gas prices vary significantly by region due to differences in local taxes, refinery capacity, transportation costs, and distribution networks. While the national average for regular gasoline is $4.02–$4.11, individual states and cities see considerably different prices. A motorist in California might pay $5.00 or more per gallon while someone in a Gulf Coast state pays closer to $3.50—both within the same week.
This regional variation means that a national statistic, while accurate overall, can feel completely disconnected from local experience. The same applies to the 70% diesel increase claim: it’s accurate for Arizona but misleading if applied nationally. Consumers in states where prices increased 40% might be confused or skeptical when hearing about 70% increases, not realizing the speaker is referencing a different state or fuel type. This fragmentation of local experience across a large country creates an environment where competing claims about the “true” price increase can feel simultaneously valid and contradictory.
What Happens Next—EIA Forecasts and Future Price Direction
The Energy Information Administration’s forecast of $3.34 per gallon for the full year 2026 now appears optimistic given current prices exceeding $4.00 in early April. If prices remain elevated for the remainder of spring and summer—historically the peak driving season—the annual average could reach $3.60–$3.80 or higher. This revised outlook would still fall short of a 70% annual increase from the previous year’s $3.00 baseline, but it would mean household gas costs remain significantly elevated longer than previously expected.
The trajectory depends largely on whether the Middle East conflict stabilizes and the Strait of Hormuz reopens to normal shipping. If resolution occurs in the coming weeks, crude oil prices could moderate, bringing pump prices down toward more normal levels. If the disruption persists through summer, consumers should expect continued high fuel prices affecting travel, transportation, and food costs. Policymakers and analysts will continue to debate whether price increases were inevitable, whether they could have been mitigated, and who bears responsibility—but the underlying economic reality of higher fuel costs will persist regardless of the political narrative.
Conclusion
Trump’s 70% gas price increase claim does not match official EIA data for regular gasoline, where the actual increase was 33–38% year-over-year. The figure may conflate diesel fuel increases (up 50.2% nationally, as high as 68.8% in specific states) with general gasoline statements, or it may reference a single state’s experience as if it were national. What is true is that fuel prices have risen substantially and meaningfully—enough to cost the average household hundreds of dollars extra annually—without requiring exaggeration.
Understanding the actual numbers matters for informed civic participation. The real story of fuel price increases—driven by geopolitical disruption, supply constraints, and market dynamics—is significant enough on its own merit. When political claims diverge from verifiable data, it invites reasonable skepticism and undermines trust in commentary about issues that genuinely deserve public attention. Consumers should rely on EIA data and current pump prices from reliable sources when evaluating their own fuel costs and understanding what’s driving changes in their household budgets.
