The financial toll of America’s six-month-old war with Iran has climbed sharply, with the Congressional Budget Office putting the total cost at $38 billion so far and warning that another $3 billion a month will pile up if the conflict continues, prompting growing questions over whether the campaign is proving more costly than the White House anticipated.
The CBO’s report, released this week, found that the war is straining US munitions stockpiles while also feeding inflation, compounded by Iran’s continued blockade of the Strait of Hormuz, a critical global oil export route. Separately, a Pentagon report covering the period through June 30 found that the conflict had caused $184 million in damage to US facilities in the Gulf, destroyed or damaged dozens of aircraft including at least 30 MQ-9 Reaper drones, and killed at least 18 US military personnel. Trump has pushed back on the munitions shortage concerns, insisting the US has virtually unlimited ammunition, a claim the White House and Pentagon have echoed in disputing the CBO’s findings.
Beyond direct military spending, the broader economic fallout has been significant. According to the Brown University Iran War Energy Cost Tracker, Americans had paid an extra $87 billion in higher fuel costs since the war began, as of mid-August, amounting to more than $660 per household. Moody’s Analytics chief economist Mark Zandi estimated the war’s combined toll, spanning military spending, higher interest rates and increased costs for fuel and groceries, at more than $1,200 per household by late July. Rising borrowing costs have added to the strain, with the 30-year Treasury yield climbing to 5.32% in mid-August, its highest level in nearly two decades, a jump expected to push up mortgage and credit card rates for ordinary Americans.
Political resistance to the war has also grown. In the latest of three attempts, seven House Republicans joined Democrats this week in voting for a resolution to end the conflict, with three of them backing such a measure for the first time. Critics have also pointed to broader strategic costs, arguing that Washington’s redeployment of military resources to the Middle East has left allies in Asia uneasy about reduced US attention on China and North Korea, while China itself has sought to position itself as a more stable global actor by contrast.
The Trump administration maintains that the costs, however steep, are justified by the goal of preventing Iran from acquiring a nuclear weapon. Whether the war is ultimately judged a strategic success or a costly overreach is likely to remain a matter of political debate as the financial and human toll continues to climb ahead of the midterm elections.
