The US-Iran conflict has reached a significant financial milestone, with the Congressional Budget Office (CBO) reporting expenditures of approximately $38 billion through August 1, 2026. This figure aligns closely with the Defense Department’s earlier estimate of $37.5 billion highlighting the substantial economic burden of the ongoing conflict.
The financial impact extends beyond direct military spending, as the CBO projects the war will contribute to inflation, adding roughly 0.5 percentage points to the price index for personal consumption expenditures by the first quarter of 2027. This increase is primarily driven by disruptions in oil and natural gas shipments through the Strait of Hormuz and the Red Sea which have escalated energy prices and strained global supply chains.
Direct Costs and Munitions Depletion
The bulk of the spending—$21.7 billion—has been allocated to replacing munitions expenditures including $13.1 billion for missile defense interceptors and $7.3 billion for land-attack cruise missiles. Additional costs cover equipment repairs, increased flying hours, and elevated fuel consumption. However, the CBO’s analysis does not account for the damage to US bases and facilities in the Middle East.
A separate report from the Defense Department’s inspector general revealed that repairing physical damage from Iranian strikes to US diplomatic facilities in IraqKuwaitSaudi Arabia and the UAE has cost approximately $184 million. The report also detailed significant losses, including four destroyed F-15 fighter jets seven KC-135 tanker aircraft and up to 30 MQ-9 Reaper drones.
Long-Term Financial Implications
The CBO estimates that replenishing the depleted munitions stockpiles could take five years or longer suggesting the true cost of the conflict will not be fully known until the Pentagon invests in rebuilding its inventories and restoring pre-war capabilities. This long-term financial commitment raises concerns about the sustainability of the conflict and its impact on the US economy.
Top administration officials have repeatedly denied claims of US munitions shortages, despite the Defense Department urging the defense industry to increase weapons manufacturing last month. The CBO’s findings provide Congress with an independent assessment to evaluate the Trump administration‘s requests for continued funding of the military campaign in Iran.
Political and Economic Repercussions
Democrats have seized on the CBO’s report to argue that the funds could have been better spent addressing domestic issues, such as easing the cost of living. Rep. Brendan Boyle the ranking member of the House Budget Committee, criticized the administration’s spending priorities, stating that the war has left Americans to bear the financial burden.
The national average price of regular gasoline has risen to $4.33 per gallon, while diesel prices have surpassed $6 per gallon, increasing the cost of moving goods across the country. The Energy Department forecasts that gasoline prices will remain near $4 for the rest of the year, further exacerbating inflation concerns.
As the conflict continues, the financial and economic implications for the US grow more pronounced. The CBO’s report underscores the need for a comprehensive assessment of the war’s costs and a strategic plan to mitigate its long-term impact on the US economy and global stability.
