The US Congressional Budget Office stated that the Trump administration spent $38 billion on Iran in the five months leading up to the war, and that each month of the war would increase costs by $2 billion to $3 billion. The war has hindered energy transportation in the Strait of Hormuz, and it is expected that the US inflation index will be 0.5 percentage points higher than expected in early 2027, with core PCE inflation being 0.3 percentage points higher. The replenishment of ammunition inventory consumed in war requires more than 5 years, putting pressure on the production capacity and inventory replenishment speed of the US military industry.
