How could the structural shift in fuel prices affect Congress?
Diesel price premium tied to federal tax structure The structural premium that causes diesel to cost substantially more than gasoline is partly attributed to federal taxation. According to the reports, federal taxes are six cents per gallon higher on diesel than on gasoline. This tax differential, combined with changes in fuel specifications and refining economics since the mid-2000s, created the long-term structural premium that the Energy Information Administration is tracking.

How it reaches Congress
-
The Energy Information Administration reported a structural shift in the relationship between diesel and gasoline prices. Historically, diesel was often cheaper than gasoline in the United States, but this pattern began changing around 2004. Currently, diesel trades at an unusually large premium over gasoline, a gap attributed to both long-term structural changes and immediate market pressures in 2026.
The full event3independent outlets -
The Energy Information Administration reports that the persistent premium of diesel over gasoline is a result of several factors, including federal taxes that are six cents per gallon higher on diesel than on gasoline. These taxes, along with changes in fuel specifications and refining economics, created the structural premium that has been in place since 2004.

Why it matters
The tax structure on fuels is a key component of the national energy economy, directly influencing consumer costs and the profitability of refiners. Since Congress controls federal tax policy, the structural factors driving the diesel-gasoline price gap are inherently tied to legislative decisions regarding fuel taxation.
This structural premium is distinct from temporary market spikes caused by global supply disruptions, such as those seen in 2022. The report emphasizes that while global events can cause the premium to explode, the underlying, long-term difference is rooted in structural changes, including the tax differential, which Congress has influenced.
