The global diesel crunch could keep fuel supplies tight into 2027 despite an expected increase in refinery output, according to the International Energy Agency’s October 14 report. U.S. diesel averaged $6.18 a gallon on October 12, while East Coast inventories remained below seasonal norms, raising cost and supply concerns for trucking companies, manufacturers and fuel distributors.
Key Takeaways
- Global diesel and gasoil exports in September 2026 fell about 700,000 barrels a day from a year earlier, according to the IEA
- U.S. on-highway diesel averaged $6.179 a gallon on October 12, down from $6.529 on September 21
- East Coast distillate inventories stood 32% below their five-year seasonal average in September
- The EIA forecasts average diesel prices of $4.49 a gallon in 2027, while the IEA expects global fuel stocks to take longer to recover
Global Diesel Crunch Deepens as Overseas Exports Decline
The International Energy Agency’s October 14 oil market report identifies a refined-fuel shortage extending beyond the availability of crude oil. Combined diesel and gasoil exports from the Middle East and Russia declined by roughly 1.3 million barrels a day in September compared with a year earlier. Additional shipments from other countries only partly replaced those losses.
The agency estimated that global diesel and gasoil availability during the third quarter was 1.7 million barrels a day lower than in the same period of 2025. Refinery disruptions and reduced export flows contributed to the decline, even as high fuel prices weighed on consumption in some markets.
Diesel demand differs from demand for fuels that can be more easily deferred. Trucks, construction equipment, farm machinery and distribution networks continue to require fuel for scheduled operations. Reduced global availability can therefore keep pressure on wholesale prices even when overall oil demand weakens.
An October 2 plan for a coordinated emergency diesel release sought to add fuel to the market. The agreement covers oil and refined products, although the exact diesel share was not specified. The IEA’s October outlook still anticipates a prolonged period of depleted inventories.
U.S. Diesel Prices Near $6.18 Add Pressure to Freight Costs
The national average price of on-highway diesel was $6.179 per gallon on October 12, according to the Energy Information Administration (EIA), down two cents from the previous week. It was also below the $6.529 recorded on September 21, but remained more than $2.50 higher than a year earlier.
That price matters across the freight network. American Trucking Associations estimates that trucks moved 72.7% of domestic freight by weight in 2024. The sector connects manufacturers, agricultural producers, distribution centers and retailers through transportation networks that depend heavily on diesel.
Fuel is a significant operating cost for carriers transporting manufactured goods, groceries and industrial materials. Changes at the pump can reach shippers through fuel surcharges, contract adjustments or higher spot-market charges. The extent depends on each carrier’s agreements, routes and fuel consumption.
The current pressure follows the September surge in crude prices that raised energy costs for businesses. Diesel and crude prices are connected, but diesel also responds to refinery output, distribution expenses and the availability of finished fuel.
Higher diesel prices can also affect agricultural operations, construction projects and regional deliveries. Equipment operators and businesses that purchase fuel directly face different costs from companies relying on contracted transportation services.
The EIA forecasts national diesel prices averaging $5.19 a gallon in 2026 and $4.49 in 2027, compared with $3.66 in 2025. Those figures indicate an expected decline from current levels rather than a return to the prices prevailing before this year’s supply disruption.
East Coast Diesel Inventories Remain Below Seasonal Norms
The East Coast enters the winter heating season with less distillate fuel in storage than usual. The EIA reported that regional inventories in September were 32% below their 2021–2025 seasonal average and forecast a shortfall of 20% to 30% through the approaching winter.
The region uses more distillate fuel than its refineries produce. Supply comes from Gulf Coast pipelines and ships, along with imports that help meet winter demand, particularly in the Northeast. In 2025, East Coast imports averaged 124,000 barrels a day, roughly 10% of regional consumption.
Canada accounts for an important share of the Northeast’s imported distillate supply, according to the EIA. Imports typically increase between December and February, when heating requirements add to regional demand.
Diesel for commercial vehicles and heating oil belong to the broader distillate category. As colder temperatures increase heating demand, both depend on refinery production and regional fuel movements. Limited inventories could make replenishment more difficult if international supply stays restricted.
The EIA forecasts East Coast distillate inventories dropping to 22.6 million barrels in April 2027, about 21% below the five-year average. It then expects stocks to rise to 31.2 million barrels by December 2027, still roughly 15% below average.
These figures measure reduced reserves rather than confirmed shortages at individual terminals. Actual fuel availability will depend on regional deliveries, import volumes, refinery operations and seasonal consumption.
Higher Refinery Output May Not Restore Diesel Stocks Until 2027
The IEA forecasts worldwide refinery processing to rise from 81.3 million barrels a day in October to 84.6 million by the end of 2026. It expects increased output to return global gasoil and diesel markets to a quarterly surplus in early 2027.
A surplus, however, does not automatically restore the inventories already consumed. The agency expects normal seasonal stock rebuilding in early 2027 but says it will not offset the deficit accumulated in 2026. Recovering lost stocks beyond ordinary seasonal changes is unlikely before the second half of 2027.
The outlook also depends on the restoration of refined-product exports from the Middle East. The IEA identifies that recovery as an important factor in determining whether additional supplies can meet demand without further reductions in consumption.
Higher refinery activity could ease some pressure on wholesale fuel markets, although regional distribution costs and inventory conditions may produce different outcomes across the United States.
The EIA’s domestic forecast points in the same general direction. It expects U.S. distillate inventories to remain below their 2021–2025 average throughout 2027, with diesel prices staying above $4 a gallon even as crude prices and refinery margins ease.
For U.S. supply chains, the global diesel crunch therefore presents a measurable cost and inventory concern rather than a confirmed nationwide fuel outage. Its duration depends on refinery recovery, the resumption of exports and the pace at which regional inventories are replenished.
Frequently Asked Questions
Why could the global diesel crunch continue into 2027?
The IEA expects refineries to increase output, but that production may not replace inventories depleted during 2026 until later in 2027. Reduced exports from major producing regions have contributed to the shortage.
What is the latest U.S. diesel price?
The EIA reported a national on-highway diesel average of $6.179 a gallon for October 12, 2026. That was below September’s peak but substantially above the price a year earlier.
Could diesel prices fall in 2027?
The EIA forecasts U.S. retail diesel averaging $4.49 a gallon in 2027, down from a projected $5.19 in 2026. These are forecasts and may change with supply, demand and crude prices.
Why is the East Coast especially exposed to tight diesel supplies?
The region consumes more distillate fuel than it produces and relies on shipments from other states and overseas. Its inventories were 32% below their five-year seasonal average in September 2026.
