U.S. Gas Prices Top $4.50 as Iran Conflict and Refinery Outages Tighten Supply
5/1/2026, 3:02:44 PM
Immediate Spike
On April 29, 2026 the U.S. national average for regular gasoline hit $4.23 per gallon; analysts warned it could rise to $4.50 as oil markets react to geopolitical risk.
Geopolitical Drivers
Two forces drive the surge: renewed U.S.–Iran hostilities threatening Hormuz oil shipments, and unplanned shutdowns at BP’s Northwest Indiana and St. Louis refineries reducing domestic fuel output.
Key Analysts
Patrick De Haan (GasBuddy) linked the jump to the Iran conflict and refinery outages.
Price Data
EIA breaks gasoline cost into 51 % crude, 20 % refining, 18 % taxes, 20 % distribution/marketing; diesel: 41 % crude, 24 % distribution, 18 % refining, 17 % taxes. April 29 averages: California $5.98, Hawaii $5.63, Washington $5.54, Oregon $5.12, Nevada $5.09; Indiana $4.30, Michigan $4.89 cash.
Driver Impact
Michigan drivers faced $100 fill-ups for large SUVs; Indiana saw an 84-cent weekly rise. Indiana’s 36-cent excise tax adds to motorists’ burden.
Official Responses
API states, “Gasoline prices reflect costs across the fuel supply chain—from crude oil production to refining, distribution and retail sales.” EIA’s breakdown underscores crude oil’s dominant role. Governor Mike Braun announced a one-month suspension of state gasoline sales tax, expiring May 8, while the excise tax stays.
Tax Criticism
Consumer groups say the sales-tax holiday offers limited relief since Indiana’s 36-cent excise tax, the bulk of fuel tax, remains unchanged. Braun noted he cannot extend the exemption beyond the 60-day limit.
On-Ground
Demare Kemp called the surge “crazy” and “insane.” Indianapolis resident Lex Peterson, who never owned a car, said he spent “zero dollars” on gas and now bikes daily.
Conflicts & Gaps
One source projects the national average could hit $4.50 per gallon; another forecasts $4.30. EIA’s gasoline cost percentages total 109 %, suggesting overlap or reporting error.
