Iran war has cost the US more than $38B, budget office says
Summary
The U.S. war against Iran has cost the Department of Defense more than $38 billion through Aug. 1 and could keep costing up to $3 billion a month, according to the Congressional Budget Office. The conflict is also expected to push inflation higher into early 2027 because of disrupted oil, gas, and shipping routes.
