Where Gas Is Cheapest Right Now: A State-by-State Breakdown

U.S. retail gasoline prices have edged lower, with AAA reporting a national average for regular of $2.93 on Dec. 12—down from $2.98 a week ago, $3.08 a month ago and below last year’s $3.03—offering modest consumer relief into the holiday season. Prices vary sharply by state: Oklahoma is cheapest at $2.36/gal, Texas, Colorado and Iowa around $2.51, while Hawaii ($4.45), California ($4.40) and Washington ($4.04) top the list; Oregon and Alaska round out the most expensive states. AAA and the article point to state fuel taxes, proximity to refineries and pipelines, and state-specific fuel blends (notably California’s) as key drivers of regional dispersion, and note fuel-efficiency and trip-planning measures as ways for drivers to reduce costs.

Analysis

AAA reports the national average price for regular gasoline at $2.93 on Dec. 12, down from $2.98 a week earlier and $3.08 a month earlier, and slightly below last year’s $3.03; the report also notes the historical peak national average of $5.02 on June 14, 2022. This steady slide into the holiday season represents modest consumer relief but remains unevenly distributed across states.

State-level dispersion is pronounced: Oklahoma posts the lowest statewide average at $2.36 per gallon, Texas, Colorado and Iowa are about $2.51 and Arkansas $2.52, while Hawaii ($4.45), California ($4.40) and Washington ($4.04) exceed $4.00; Oregon ($3.65) and Alaska ($3.63) also sit well above the national average. These gaps matter for regional transport costs, household discretionary spending, and competitive dynamics for businesses operating across state lines.

The Energy Information Administration attribution—taxes accounting for more than 14% of the price in 2023—along with proximity to refineries/pipelines and state-specific fuel blends (notably California’s cleaner-burning mandate) explain much of the variance. AAA’s recommended demand-side responses (smoother driving, maintenance, trip planning) could modestly reduce consumption and temper short-term retail volatility, but structural tax and refining differences imply persistent regional price differentials.

Key Decisions for Investors

• Adjust cost and margin models for transportation and consumer-facing companies regionally—expect lower fuel headwinds in Oklahoma, Texas and nearby states and persistent cost premiums in California, Washington and Hawaii
• Monitor state tax policy and California fuel-blend/regulatory developments as potential catalysts for sustained regional price differentials and volatility
• For logistics or fleet-exposed investments, consider tactical hedges or operational routing to mitigate a roughly $2.04/gal regional spread between cheapest and priciest states (Oklahoma vs. California), and stress-test margins accordingly
• Factor modestly lower national fuel costs into short-term consumer demand forecasts for holiday spending but watch for any supply or policy shifts that could reverse the recent downward trend
