Latest Data Shows a Change in Gas Prices

Gas and Diesel Prices Surge as Global Oil Supply Tightens, With More Increases Possible

American drivers are facing another sharp increase in fuel costs as gasoline and diesel prices climb amid disruptions to global oil supplies and continuing conflicts involving Iran, Russia and Ukraine.

The latest surge has pushed U.S. diesel prices to record territory, while gasoline has climbed well above year-ago levels. Energy analysts are warning that retail prices could rise further in the coming days as service stations continue passing along earlier increases in wholesale fuel costs.

The increases are being driven by a combination of geopolitical disruptions, constrained inventories and unusually tight refining markets.

Diesel Has Reached a Record High

Diesel prices have become one of the most significant pressure points in the U.S. fuel market.

GasBuddy reported earlier this month that the national average for diesel had crossed $6 per gallon for the first time, while subsequent market data placed the average around $6.27 to $6.31 per gallon by Sept. 15-16.

The increase is particularly important because diesel is widely used to transport goods and agricultural products. Higher diesel costs can therefore affect businesses well beyond the gas station, potentially adding pressure to transportation, food and other consumer prices.

U.S. distillate inventories remain significantly below normal levels. The Energy Information Administration data reported this week showed distillate stocks at about 107.9 million barrels, roughly 13% below the five-year average.

Gasoline Prices Are Also Rising

Gasoline prices have followed the broader increase in energy costs.

The national average for regular gasoline has moved above $4.30 per gallon, with recent reports placing it around $4.32 to $4.37 depending on the data source and timing.

That represents a substantial increase from a year ago.

Regional differences are particularly pronounced. California continues to record some of the country’s highest gasoline prices, while several Western states have also seen averages above $5 per gallon.

Prices vary considerably from one station and region to another, meaning the national average does not necessarily reflect what an individual driver will pay.

Analysts Warn Retail Prices May Still Be Catching Up

Energy analyst Tom Kloza has warned that the retail market has not fully reflected previous wholesale increases.

Kloza said fuel margins had not yet caught up with earlier wholesale price increases, creating the possibility of another substantial move at the pump.

He specifically pointed to the Great Lakes and Rocky Mountain regions as areas where increases could be particularly noticeable.

Those comments represent a forecast rather than a guarantee. Retail gasoline and diesel prices can change rapidly depending on crude-oil prices, refining costs, inventories, transportation expenses and local competition.

GasBuddy Analyst Also Expects More Volatility

GasBuddy petroleum analyst Patrick De Haan has similarly warned that fuel prices could move higher.

De Haan has said diesel could reach approximately $6.60 per gallon if current market conditions persist.

That figure is a projection, not a current national average or an established future price.

The market has already demonstrated how quickly prices can change. Diesel moved above $6 nationally for the first time earlier this month, with prices continuing to rise afterward.

Iran Conflict Is Disrupting Global Oil Supplies

The conflict involving Iran is a major factor behind the current energy shock.

Disruptions around the Strait of Hormuz, a crucial route for international oil shipments, have tightened global supplies and pushed crude prices above $100 per barrel.

The effects extend well beyond the Middle East because oil is traded in a global market. Even countries that produce substantial amounts of crude can face higher domestic fuel prices when international supplies become more expensive.

The Washington Post reported that the effects of the conflict are now feeding into U.S. gasoline and diesel markets, with analysts expecting additional price increases as supply disruptions work their way through the fuel system.

The Russia-Ukraine War Is Adding Further Pressure

The continuing Russia-Ukraine conflict is another factor affecting fuel markets.

Ukrainian attacks on Russian refineries have reduced some refining capacity, while Russia has also restricted fuel exports to protect its domestic market.

Those disruptions are particularly important for diesel because the international market was already facing tight supplies.

Reuters reported that Ukrainian attacks on Russian refineries, combined with restrictions on fuel exports from Russia and China and disruptions linked to the Iran conflict, have contributed to the sharp increase in U.S. diesel prices.

U.S. Inventories Are Under Pressure

Domestic inventories provide another indication of how tight the market has become.

According to the latest EIA data, U.S. distillate inventories increased during the most recent reporting week but remained about 13% below the five-year average. Gasoline inventories were also approximately 5% below the five-year average.

At the same time, U.S. refineries are operating at high utilization rates.

The latest data showed refinery utilization at approximately 96.8%, leaving relatively limited additional capacity to rapidly increase fuel production if global supplies remain disrupted.

That combination—high refinery utilization and below-average inventories—helps explain why changes in global crude and refined-product supplies can quickly affect American fuel prices.

Why Diesel Prices Matter Beyond the Pump

Diesel’s importance extends far beyond individual motorists.

Trucks rely heavily on diesel to move products across the country. Agriculture also depends on diesel-powered machinery, while construction, manufacturing and other industries use diesel for transportation and equipment.

When diesel becomes substantially more expensive, companies can face higher operating costs.

Those costs can eventually be reflected in prices for goods and services, although the timing and size of the effect varies from industry to industry.

The Associated Press has reported that the diesel surge is already creating additional pressure throughout transportation and supply chains, with potential implications for the cost of food and other goods.

Why September’s Price Surge Is Unusual

Fuel prices often follow seasonal patterns.

Gasoline demand typically eases after the summer driving season, and refiners traditionally transition toward winter gasoline formulations.

This year, however, geopolitical disruptions have complicated that seasonal pattern.

Instead of receiving the usual post-summer relief, motorists are facing a market characterized by tight supplies and elevated crude and refined-fuel prices.

That does not necessarily mean prices will continue rising indefinitely. A reduction in geopolitical tensions, increased production, improved shipping conditions or weaker demand could reverse some of the recent increases.

What Drivers Could See Next

The immediate outlook remains highly uncertain.

Analysts are warning that retail prices could continue climbing as stations pass through previous wholesale increases. But the ultimate direction of prices will depend heavily on developments in global oil production, shipping, refining capacity and the conflicts affecting major energy-producing regions.

For consumers, the key distinction is between current prices and forecasts.

A national diesel average around $6.30 per gallon is a reported market level, while a projection that diesel could reach $6.60 represents an estimate based on current conditions.

Neither gasoline nor diesel prices are guaranteed to follow a straight upward path.

The Bottom Line

U.S. drivers are facing an unusually expensive fuel market, with diesel prices reaching record territory and gasoline prices climbing sharply from their levels a year ago.

The increase is being driven by several overlapping factors, including disruptions connected to the Iran conflict, attacks affecting Russian refining capacity, export restrictions and below-average U.S. fuel inventories.

Analysts including Tom Kloza and Patrick De Haan have warned that another increase could arrive as retailers catch up with earlier wholesale price movements. Their forecasts should be viewed as projections rather than guaranteed outcomes.

For now, the combination of tight global supplies, elevated crude prices and limited fuel inventories leaves American motorists and businesses facing continued uncertainty at the pump.
