The Congressional Budget Office estimated that the U.S. war with Iran had cost $38 billion, with $25 billion of weapons expended, and said the conflict would add about $3 billion a month if it continued. The office projected that disruptions to oil and gas flows through the Iranian-blockaded Strait of Hormuz would raise U.S. inflation by 0.5 percentage point in the first three months of 2027. Its assessment reinforced a Pentagon inspector general finding that munitions inventories, particularly defensive systems, face supply-chain bottlenecks. The war, launched with Israel on Feb. 28, has entered its seventh month despite President Donald Trump's earlier projection that it would last four to five weeks. Public support has fallen, while rising fuel costs, federal debt and congressional opposition have become central issues ahead of the Nov. 3 midterm elections.
