U.S. national average gasoline prices have surged to around $4.00 per gallon as of late March 2026, up over 25% from early-month levels near $3.00, primarily driven by crude oil benchmarks exceeding $99 per barrel for WTI amid escalating Middle East tensions including Iran-related disruptions. EIA data shows gasoline inventories declining 2.6 million barrels for the week ending March 20, compounded by seasonal spring break demand and refinery maintenance constraints. This upward momentum reflects trader consensus on sustained supply tightness, with RBOB gasoline futures climbing above $3.25/gallon. As the market nears end-of-March resolution, weekend pump surveys and any geopolitical de-escalation could trigger final volatility, while broader inflation impacts loom from higher energy input costs.
