The US war against Iran has resulted in significant costs for the Department of Defense, exceeding $38 billion through August 1. Ongoing expenses are expected to range from $3 billion to more per month, depending on the conflict's intensity.

The nonpartisan Congressional Budget Office released this assessment, which also notes that the war will contribute to inflation. This is largely due to disruptions in oil and natural gas shipments, as well as shipping through the Red Sea.

Further details on the estimated costs and impact on inflation are available from the Congressional Budget Office's assessment, which was released in response to a request from a House Budget committee member.
