Quick Summary

The Congressional Budget Office reports that the war with Iran has caused more than one-third of the inflation increase this year and forecasts higher inflation rates into 2027. The report attributes the rising costs mainly to reduced oil and natural gas shipments through critical shipping lanes, leading to a significant rise in gasoline and diesel prices. Interest rates are expected to continue increasing, making borrowing more expensive for Americans.

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.

🔮 President Donald Trump is weighing options for his war on Iran — including new strikes — despite his initial promises to Americans that the campaign would last a matter of weeks.
🔮 The ship is still under construction but is set to be named in honor of Miller, an enlisted sailor who famously staffed an anti-aircraft gun during the Japanese attack on Pearl Harbor in 1941.
🔮 While the Pentagon has provided some estimates, it has not detailed the total cost of the war, including how much it would cost to repair damage to U.S. military bases, to replace destroyed air and naval assets and to refurbish ships and aircraft ground down by seven months of war.
🔮 The war with Iran is driving up inflation, and borrowing costs may increase for Americans, according to a new report released Tuesday by the Congressional Budget Office.
🔮 Trump initially said the war would last for only weeks.

Sen. Elizabeth Warren, D-Mass., called for an end to the war in a statement, describing it as “a one-two punch that’s burning a hole in Americans’ pockets and burning a hole in our munitions supply, hurting our military readiness.” The report estimated it would cost $13.1 billion to replace missile defense interceptors alone, and the overall cost to replace munitions expended through Aug. 1 would be $21.7 billion.
