The armed conflict with Iran has pushed total publicly mentioned military expenditures to 45,1 miljardu dolāru. The latest estimates from the Pentagon and the Congressional Budget Office (CBO) outline a conflict that continues to drain defense stockpiles at a rate of billions per month while driving up broader economic inflation.
Conflicting Cost Estimates Between Pentagon and CBO Reports
According to CNN sources, these figures still do not represent a complete accounting of total war costs. Pentagons calculations omit funds required for repairing military sites, structures, and bases damaged during operations, while Congress has received no detailed breakdown of several indirect military operational costs.
These figures stand significantly higher than previous forecasts. According to data cited by CNN, the CBO estimated in mid-September that war costs had reached roughly 38 miljardus dolāru through August 1. That matches the 38 miljardus dolāru figure reported independently by diena.lv for the exact same timeframe, referencing the joint U.S. and Israel offensive launched against Iran on February 28. Earlier in July, Defense Secretary Pete Hegseth valued the conflict expenditures at 37,5 miljardu dolāru.
Munitions Replacement and Interceptor Depletion
Munitions and weaponry make up the vast majority of operational expenses. According to CBO findings reported by diena.lv, replacing utilized munitions cost 21,7 miljardus dolāru up to August 1, marking the Defense Department’s largest single cost driver in the conflict.
Pro tip: Analysts look closely at interceptor inventory levels rather than just raw dollar amounts to gauge long-term military readiness during sustained Middle East engagements.
The CBO warned that the primary alternative cost is the severe depletion of air defense interceptor missile stockpiles, leaving the United States with reduced reserves for years. By comparing reported spending against total munitions acquired by the Defense Department, the CBO calculates that the U.S. may have utilized between half and two-thirds of this specific munition inventory since June 2025. Analysts project that even without major escalation, the war will continue costing between 2 un 3 miljardiem dolāru monthly.
Economic Impact and Hormuz Strait Supply Pressures
The financial fallout extends well past federal defense accounts. According to CBO projections cited by diena.lv, U.S. inflation measured by the personal consumption expenditures price index will run 0,5% higher in the first quarter of next year than February projections indicated. CNN noted that supply chain volatility and energy price spikes stem heavily from tensions in the Hormuz Strait, a critical transit corridor for global oil and liquefied natural gas.

Did you know? Iran responded to the military campaign by blocking the Hormuz Strait, disrupting global petroleum shipments and driving up domestic fuel costs across Western markets.
