Quick Summary

The Congressional Budget Office reported that as of August 1, 2026, the war with Iran has cost the US military approximately $38 billion, with potential monthly expenses ranging from $2 billion to over $3 billion depending on conflict intensity. The CBO’s analysis was requested by Democratic lawmakers and includes inflationary pressures due to disruptions in oil and natural gas supplies following Iran's blockade of the Strait of Hormuz. This has led to projected higher inflation rates for the first quarter of 2027, with core inflation also expected to rise.

Story summary

As of August 1, 2026, the armed conflict with Iran has cost the U.S. military approximately $38 billion, according to a report by the Congressional Budget Office (CBO). The war began in late February following US-Israeli strikes targeting Iran. Monthly costs could range between $2 billion and $3 billion depending on the intensity of violence, with inflation rates projected to rise due to increased energy prices. The CBO highlights that fewer oil and natural gas shipments through critical passageways like the Strait of Hormuz are exacerbating inflation. Additionally, the war has significantly depleted U.S. inventories of missiles and anti-air defense weapons, potentially leaving the Pentagon vulnerable if another major conflict arises within the next five years.
