The national average for regular gasoline climbed to $4.46 per gallon on September 18, 2026, as Brent crude oil prices surpassed $100 per barrel. This shift in energy markets impacts overhead for companies managing fleet operations or logistics.
Why it matters
The persistent regional conflict involving Iran and Israel continues to disrupt global energy supply chains and drive price volatility. For operators, this creates sustained pressure on variable expenses like shipping and delivery.
The national average for gasoline reached $4.46 per gallon, while diesel prices spiked to a range between $6.40 and $6.44 per gallon. Crude oil prices moved above $100 per barrel amid market uncertainty.
The players
Iran
A major energy producer and central party to the regional conflict impacting global supply chains.
Israel
A participant in the regional conflict currently driving energy market volatility.
The details
Rising Brent crude costs are being passed through to the pump as regional tensions create anxiety over supply routes near the Strait of Hormuz. For businesses, this volatility complicates fuel surcharges and baseline shipping costs. These higher energy inputs are a direct result of market reactions to the ongoing conflict involving Iran and Israel.
Timeline
June 2022 saw a record national average gasoline price of $5.01.
May 21, 2026, marked the year's high for gasoline at $4.56 per gallon.
September 17, 2026, recorded a national gasoline average of $4.44.
September 18, 2026, saw the national gasoline average reach $4.46.
Market Landscape
This development tracks a pattern of volatility similar to the market stress that pushed national average gasoline prices to a record $5.01 in June 2022. The current reliance on Brent crude pricing reflects an ongoing sensitivity to regional instability in major transit corridors.
Operators should review current fuel surcharges and logistics contracts to determine if they adequately account for diesel prices holding at or above $6.40 per gallon. Monitor Brent crude benchmarks as a proxy for potential further adjustments to your operating expenses.
The takeaway
Energy price spikes illustrate the need for flexible logistics contracts that can absorb rapid increases in fuel inputs. Track Brent crude benchmarks weekly to anticipate shifts in your transport and supply chain costs.
