Diesel Prices Surge Nationwide in Latest EIA Update

Diesel Prices Jump Nationwide After Two Weeks of Declines

Diesel Prices increased sharply across the United States during the week ending July 13, reversing two consecutive weeks of declines and posting the largest weekly increase since early this year.

According to the U.S. Energy Information Administration (EIA), the national average on-highway diesel price climbed 21.8 cents to $4.796 per gallon, with nearly every region reporting higher prices.

Gasoline prices also moved higher during the week, although the increase was much smaller than diesel.

Why Diesel Prices Increased

The sharp increase in Diesel Prices comes as global fuel markets continue to face supply concerns.

Diesel prices have been pushed higher by a combination of Russia’s diesel export restrictions and renewed uncertainty surrounding shipments through the Strait of Hormuz, one of the world’s most important oil transit routes. Those factors have tightened global diesel supplies after prices had declined for two consecutive weeks.

Renewed geopolitical tensions involving Iran have driven crude oil prices to their highest levels in about a month, increasing concerns about future fuel supplies and adding upward pressure to diesel markets.

Although the national diesel average rose 21.8 cents this week, future price movements will likely depend on global energy markets, refinery production, and international supply conditions.

Diesel Prices Rise Across Nearly Every Region

The latest Diesel Prices report showed increases in every major region except New England, where prices declined slightly.

The largest weekly increases included:

• Gulf Coast: up 32.1 cents to $4.546
• Lower Atlantic: up 27.1 cents to $4.748
• Midwest: up 20.1 cents to $4.659
• East Coast: up 20.0 cents to $4.894
• West Coast (less California): up 18.8 cents to $5.052
• Rocky Mountain: up 11.6 cents to $4.600
• West Coast: up 12.5 cents to $5.550
• Central Atlantic: up 5.8 cents to $5.204

New England was the only region to record a decline, slipping 3.1 cents to $5.189 per gallon.

California continued to post the nation’s highest average diesel price at $6.126 per gallon, increasing 5.3 cents from the previous week.

National Diesel Price Remains Above Last Year

Despite recent fluctuations, Diesel Prices remain well above year-ago levels.

The national average is now $1.038 per gallon higher than the same week in 2025 and 97 cents higher than two years ago.

Regional comparisons also showed diesel prices remaining significantly above last year’s levels across every part of the country.

Gasoline Prices Also Move Higher

Regular gasoline prices also increased during the week.

The national average rose 7.8 cents to $3.855 per gallon.

The largest gasoline increases were reported in:

• Rocky Mountain: up 16.2 cents
• Midwest: up 13.1 cents
• Lower Atlantic: up 8.0 cents
• Gulf Coast: up 8.0 cents

The West Coast (less California) was the only region to record a decline, falling 2.9 cents from the previous week.

Short-Term Energy Outlook

The U.S. Energy Information Administration’s latest Short-Term Energy Outlook (STEO) continues to project that fuel prices will remain sensitive to seasonal demand and global oil market conditions during the summer driving season.

While diesel prices can fluctuate from week to week, the EIA expects crude oil prices and fuel markets to remain influenced by supply, refinery activity, and worldwide demand in the months ahead.
