A Congressional Budget Office assessment says the US war against Iran has cost the Defense Department more than $38 billion through August 1, with spending continuing at up to $3 billion a month, and projects the conflict will keep inflation about 0.5 percentage points higher than previously estimated into early 2027.

The United States war against Iran has cost the Department of Defense more than $38 billion through August 1, according to an assessment released Tuesday by the nonpartisan Congressional Budget Office.
The estimate says the conflict will continue costing up to $3 billion a month, or more, depending on the intensity of the fighting.
The CBO said the war is expected to contribute to inflation into the first quarter of 2027, leaving inflation roughly 0.5 percentage points higher than it had previously estimated. It attributed this largely to reduced oil and natural gas shipments through the Strait of Hormuz and disruptions to shipping through the Red Sea.
The assessment was prepared in response to a request for information from Rep. Brendan Boyle, the top Democrat on the House Budget Committee. The estimate largely aligns with a previous assessment, according to the sources.
