Diesel Prices · Inflation · Oil Supply · Strait Of Hormuz
The war with Iran has brought the Strait of Hormuz, a critical global oil chokepoint, close to a standstill, causing U.S. diesel prices to surge over $1.00 per gallon in 45 states and threatening a resurgence of inflation.
Patrick De Haan, head of petroleum analysis for GasBuddy, explains that diesel fuels the U.S. economy, powering construction, agriculture, and logistics. This 2026 situation represents a major supply disruption, unlike the 2022 spike driven by demand and the Russia-Ukraine war.
The Strait of Hormuz typically handles 20% of daily global oil flow, an insurmountable loss that impacts hundreds of millions of barrels. This drives up oil, diesel, and jet fuel prices, creating collateral damage beyond fuel by affecting chemicals and fertilizers crucial for agriculture.
Inflation, which had been lessening, is now expected to swing back upwards. Oil prices could rise well beyond $100 per barrel, with some estimates reaching $150-$200, until demand falls to meet the reduced supply.
Saudi Arabia is exploring contingency plans like its East-West pipeline. If the Strait reopens, oil prices could plummet within 24-48 hours, but consumers would see full relief at the pump only after a month or more.
