Pentagon says Iran war cost at least $11.3B in first six days
The six-day operating tab excludes prep and personnel costs and could rise sharply, lawmakers were told in a closed briefing. The fighting has already tightened global energy markets — driving higher pump prices and adding immediate pressure on U.S. household budgets and congressional spending decisions.

Why it matters:
- The reported $11.3 billion shortfall in six days signals a fast-rising fiscal burden from the U.S.-Israel campaign against Iran that could force Congress to consider supplemental war funding.
Driving the news:
- Pentagon officials told senators in a closed-door briefing that the operation’s cost exceeded $11.3 billion in the first six days. - Defense briefers said about $5.6 billion of munitions were used in the first two days of strikes. - A Pentagon spokesperson declined to comment on closed-door discussions and said the total cost won’t be known until the mission is complete. - Sen. Chris Coons said the current operating total is likely “significantly above” the reported figure.
By the numbers:
- U.S. drivers are paying roughly $0.80 more per gallon since operations began — about $300 million in extra costs every day. - Brent crude jumped roughly 50%, from about $67 to over $100 per barrel, pushing national pump prices from under $3 to about $3.70 per gallon. - An independent estimate put the first 100 hours of the campaign at roughly $3.7 billion. - International Energy Agency members have agreed to coordinate release of emergency reserves, a temporary move that can only partially fill the supply gap.
State of play:
- Lawmakers pressed the administration for scope and duration details after the briefing; GOP Sen. Roger Wicker said he did not expect a supplemental request this month. - The conflict has expanded beyond initial strikes, with military activity across the region and visible impacts on shipping routes.
The risk:
- Closure or disruption of the Strait of Hormuz is cutting supply and creating sustained price pressure for fuel, air travel, and food logistics. That makes the consumer pain more than a short spike — it can roll through months of higher costs. - High early munitions use and ongoing operations mean the fiscal and economic bill could grow substantially before a political or military endpoint is reached.
The bottom line:
- The war’s early price tag is already large and accelerating economic pain at home, and Congress may soon face a consequential funding and policy reckoning.
