U.S. retail gasoline prices reflect the combined pressure of crude oil volatility, regional refining dynamics, and geopolitical risk premium flowing through the supply chain. The AAA national average currently sits at $4.058 per gallon for regular, down for seven consecutive days as the April 17 Hormuz reopening narrative briefly dominated pricing. Whether that downward trend continues depends on crude benchmarks and refinery run rates through the coming week.
Regional variation remains substantial. California retail averages above $5.15 per gallon due to the state's specific fuel formulation requirements, carbon pricing, and limited in-state refining capacity. Mississippi, Oklahoma, and Texas remain under $3.70 as Gulf Coast refineries serve their local markets with minimal transportation cost. Hawaii's unique logistics situation keeps prices elevated regardless of mainland conditions. These regional spreads can exceed $1.50 per gallon at any given time.
The pass-through from crude oil to pump prices typically runs 1-2 weeks. A $10 per barrel increase in WTI translates to roughly $0.24-0.30 per gallon at retail once the crude moves through refinery processing, wholesale rack pricing, and retail markups. Refining margins — the difference between crude input cost and finished product output price — currently sit above seasonal averages, which is providing some buffer against further pump price increases even as crude fluctuates.
Seasonal dynamics add another layer. The U.S. refinery complex completed its spring transition to summer-grade gasoline formulations in April, which adds 8-15 cents per gallon relative to winter-grade. Driving demand typically peaks Memorial Day through Labor Day, and the EIA's weekly demand figures will be closely watched for evidence of consumer response to current price levels. Absent geopolitical shock, most analysts expect pump prices to stabilize in the $4.00-4.20 range through spring.
