Gas Price Trends: Regional Differences and Impact of Geopolitical Events (Memorial Day 2026)

National Average Increase:: The average retail price for regular-grade gasoline in the U.S. on May 18 was $4.49 per gallon, a 42% increase from the previous year. This is the highest average price before Memorial Day since 2022.

Regional Disparities:: Gas prices vary significantly by region. The West Coast has the highest prices, averaging $5.61/gallon, while the Gulf Coast has the lowest at $3.95/gallon.

Impact of Refinery Outages:: Temporary refinery outages and maintenance in the Midwest and Rocky Mountain regions have contributed to price increases.

Geopolitical Influence:: Rising crude oil prices, influenced by events like the de facto closure of the Strait of Hormuz, are a major factor in the overall increase in gas prices.

Texas Advantage:: Texas enjoys lower gas prices ($4.092/gallon) due to its status as a top crude oil and natural gas-producing state with substantial refining capacity.

West Coast:: Prices are highest due to limited connections with other refining centers, tight local supply and demand, high state taxes, and unique gasoline specifications.

Gulf Coast:: Prices are typically lowest due to the region hosting over half of the U.S. refining capacity and having lower gasoline taxes.

East Coast:: Prices averaged $4.31/gallon, reflecting high gasoline demand in the region.

Midwest & Rocky Mountain:: Refinery issues have caused prices to surge, with averages of $4.40/gallon and $4.59/gallon, respectively.

Monitor regional gas price trends to find the most affordable options.

Be aware of how geopolitical events can impact crude oil and, consequently, gasoline prices.

Consider that states with high oil production and refining capacity may offer some of the lowest prices.

Stay informed about any government interventions aimed at stabilizing gas prices.
