Iran war cost hits $38 billion, forecast to rise $3 billion a month

The six-month-old U.S. war against Iran has cost $38 billion so far and that amount is projected to rise by $3 billion a month, Congress' nonpartisan

bookkeeper reported on Tuesday, as the Trump administration searches for ways to end the conflict and reopen the vital Strait of Hormuz.



The war is expected to increase inflation by 0.5% in the first three months of 2027, according to the Congressional Budget Office accounting, which totaled expenses through August 1.



The mounting costs have strained U.S. munitions stockpiles and driven up energy prices, raising concerns about the country's ability to respond to other potential conflicts and adding pressure on an already stretched federal budget.



The cost was close to the $37.5 billion that Defense Secretary Pete Hegseth reported at a Senate hearing on July 21.
