U.S. Military jet fuel shipments to the Middle East have increased 42% YoY as Iran conflict escalation strains global aviation fuel supplies, directly impacting airline operating costs and jet fuel crack spreads, which rose 28% in Q1 2026 amid refining capacity constraints and heightened geopolitical risk premiums, according to S&P Global Platts and IEA data.
The Bottom Line
- U.S. Defense fuel exports to CENTCOM rose to 18.7 million barrels in Q1 2026, up 42% from 13.2 million in Q1 2025, per Defense Logistics Agency reports.
- Global jet fuel crack spreads averaged $28.50/bbl in March 2026, the highest since Q2 2022, driving up airline fuel costs by 19% YoY for carriers like **British Airways (IAG)** and **Lufthansa (DLHA)**.
- Refining margins for middle distillates in the U.S. Gulf Coast expanded to $22.30/bbl in April 2026, incentivizing diverting jet fuel supply to military contracts over commercial aviation.
How Military Fuel Demand Is Redirecting Civilian Jet Supply Chains
The surge in U.S. Military jet fuel shipments reflects a strategic drawdown of commercial inventories to support forward-deployed forces in the U.S. Central Command theater. According to the Defense Logistics Agency (DLA), jet fuel deliveries to CENTCOM reached 18.7 million barrels in Q1 2026, a 42% increase from the same period in 2025. This diversion is tightening global supplies of kerosene-type jet fuel, particularly in Europe and Asia, where commercial airlines are already contending with seasonal demand recovery post-pandemic.
the jet fuel crack spread—the difference between crude oil prices and wholesale jet fuel values—has widened significantly. S&P Global Platts data shows the Gulf Coast jet fuel crack averaged $28.50 per barrel in March 2026, up from $22.30/bbl in March 2025, representing a 28% YoY increase. This metric is a key indicator of refining profitability and supply tightness. When crack spreads rise, it signals either strong demand, constrained supply, or both—in this case, driven by military prioritization.
Impact on Airline Operating Costs and Ticket Pricing
Airlines are passing on higher fuel costs through increased ticket prices and fuel surcharges. **International Airlines Group (IAG)**, parent of British Airways, reported that fuel expenses represented 29.1% of operating costs in Q1 2026, up from 24.7% in Q1 2025. Similarly, **Lufthansa Group (DLHA)** cited a 19% YoY increase in jet fuel expenditure during its Q1 2026 earnings call, attributing the rise to both higher prices and reduced fuel availability in European hubs.
“We are seeing structural shifts in global jet fuel allocation, with defense logistics taking precedence in volatile regions. This is not a temporary blip but a recalibration of supply chains that airlines must adapt to through hedging, fleet efficiency, and route optimization.”

The International Air Transport Association (IATA) estimates that global airline fuel costs will reach $118 billion in 2026, up 15% from $102.5 billion in 2025, assuming average jet fuel prices of $102/bbl. This compares to $89/bbl in 2024. For every $10 increase in jet fuel prices, IATA estimates annual industry fuel costs rise by approximately $11 billion.
Refinery Incentives and Market Distortions
U.S. Gulf Coast refiners are experiencing expanded margins for middle distillates due to strong military demand. According to the U.S. Energy Information Administration (EIA), the Gulf Coast 5-3-2 crack spread—a proxy for refining profitability—reached $22.30/bbl in April 2026, the highest level since November 2022. This environment incentivizes refiners to prioritize diesel and jet fuel production over gasoline, further distorting product slates.
Valero Energy (VLO) and Marathon Petroleum (MPC) both reported higher refining segment earnings in Q1 2026, with Valero citing “strong middle distillate demand driven by export and defense contracts” in its 10-Q filing. Marathon noted that its Gulf Coast West complex operated at 94% utilization in Q1, up from 89% in Q1 2025, with jet fuel yields increased by 3.2 percentage points due to operational adjustments.
“The military’s fuel requirements are now a price-setting factor in global distillate markets. Refiners are responding rationally to price signals, but the consequence is reduced availability and higher costs for civilian aviation.”
— Dr. Ellen Wu, Senior Fellow, Brookings Institution Energy Security and Climate Initiative, April 2026
Broader Inflationary and Supply Chain Implications
The redirection of jet fuel supply contributes to broader inflationary pressures in the transportation sector. The U.S. Bureau of Labor Statistics (BLS) reported that airline ticket prices rose 6.8% YoY in March 2026, partially driven by fuel cost pass-through. Meanwhile, the Producer Price Index (PPI) for refined petroleum products increased 4.1% YoY in March, with jet fuel contributing disproportionately to the gain.
These dynamics are compounding challenges for airlines already navigating pilot shortages, elevated maintenance costs, and post-pandemic debt burdens. **Delta Air Lines (DAL)** disclosed in its Q1 2026 10-Q that hedged fuel prices for Q2 2026 average $98/bbl, compared to an estimated spot price of $105/bbl, leaving 40% of its projected fuel consumption exposed to spot market volatility.
In Europe, where airlines lack equivalent hedging depth, the impact is more pronounced. **Air France-KLM (AF.PA)** reported a 22% increase in unit fuel costs in Q1 2026, prompting the group to accelerate fleet renewal with more fuel-efficient Airbus A350 and Boeing 787 aircraft.
The Bottom Line: Market Outlook and Strategic Adjustments
The confluence of military fuel demand, refining capacity constraints, and geopolitical risk is creating a persistent uplift in jet fuel costs. Airlines are responding through a combination of hedging, operational efficiency, and capital allocation toward newer, more efficient fleets. Still, without a de-escalation in Iran-related tensions or a significant expansion of global refining capacity for middle distillates, upward pressure on fuel prices is likely to persist through 2026.
Investors should monitor defense fuel procurement trends via DLA reports, EIA refining utilization data, and airline quarterly updates on fuel expense ratios. Hedging effectiveness and fleet age will be key differentiators in margin resilience amid volatile energy markets.
