Retail gasoline prices in the U.S. will drop to an average of $3.35 by 2027, according to the Energy Information Administration. The projected relief follows a severe global energy shock driven by the Iran war, which disrupted Middle Eastern oil flows and pushed the national gas average past $4 per gallon.
Refining Cracks and Supply Strains Drive Record Fuel Margins
The global energy inflation shock triggered by the conflict in the Middle East has hit refined oil products far harder than crude. While benchmark Brent crude oil traded near $90 a barrel following a retreat from wartime peaks, refined fuels have faced severe bottlenecks. The war knocked out more than 20% of the Middle East’s 9.6 million barrels per day of refining capacity, according to the International Energy Agency, while fuel exports remained suppressed due to the blockade of the Strait of Hormuz.
That pressure compounded months of Ukrainian strikes on Russian energy infrastructure, which cut Moscow’s throughput by nearly 30% to below 4 million barrels per day and prompted a July diesel export ban. Consequently, U.S. diesel margins climbed more than 140% to reach a record $100 earlier in the week. U.S. diesel inventories fell to their lowest seasonal level in three decades, and gasoline stocks reached their weakest point since 2012.
Prices at the Pump and Economic Pressures Across Sectors
At the pump, American drivers bore the brunt of the supply crunch. The national average for regular gasoline hit $4.22 per gallon on a Tuesday, according to data from the American Automobile Association.
According to reports, diesel fuel plays a critical role in transporting goods, including food, across the economy. Diesel-powered vehicles and equipment are essential for agricultural production, logistics, and infrastructure, and rising diesel prices have been linked to broader inflationary pressures.
U.S. consumer prices rose 3.4% in July from a year earlier, driven in large part by a 14.7% increase in energy costs, including a 24.6% jump in gasoline prices, according to federal inflation data.
Strait of Hormuz Disruptions and Diplomatic Outlook
Uncertainty surrounding maritime security continues to dictate commodity markets. Brent crude futures for October delivery rose 25 cents, or 0.3%, to $91.87 a barrel, while U.S. West Texas Intermediate crude futures for September slipped 2 cents to $85.81 a barrel, with the more active October contract gaining 14 cents to $84.53, according to market trading data.
Both Brent and WTI benchmarks gained for a fourth session, settling at their highest level since July 24. Regional tensions escalated further when the United Arab Emirates suspended all financial and economic transactions with Iran until further notice. President Donald Trump stated that no talks were taking place with Iran and that the Strait of Hormuz was open, though Iran asserted the waterway remained shut.
Even if a diplomatic breakthrough eventually reopens the Strait of Hormuz, analysts warn that refinery repairs will take time. More than 20 refineries across the Gulf sustained damage during the conflict, and lead times for critical equipment such as compressors and heat exchangers were stretched before hostilities began. The EIA expects constraints in the strait to leave an average of 5.7 million barrels per day of crude oil production shut in through the fourth quarter of 2026, before returning to near pre-conflict averages by the second quarter of 2027.
Data Center Expansion Drives Record U.S. Electricity Generation
While fossil fuel markets absorb wartime shocks, the domestic power sector is expanding rapidly. The EIA expects U.S. electricity generation to grow 2.2% to a record 4.37 billion kilowatt-hours this year, with an additional 1.7% growth projected for 2027. A massive boom in data center construction and increased manufacturing activity are fueling commercial and industrial demand, boosting U.S. electricity sales by 2% in 2026 to 4.14 BkWh, and another 2% in 2027. Despite a temporary pause in new data center projects in Texas, the West South Central region remains the largest regional contributor to electricity sales growth.
