The escalating military conflict between the United States and Iran is expected to have a negative impact on global markets, particularly in the defense and energy sectors. Increased defense spending by the United States and potential disruptions to oil supplies from the Middle East could lead to market volatility and higher energy prices.
The opening week of the war between the United States and Iran has cost the United States over $11.3 billion, as reported by The New York Times Company, citing a United States===The Pentagon briefing to the United States===United States Congress. This figure excludes many costs related to the buildup, suggesting the final tally could be substantially higher. Defense officials also revealed that approximately $5.6 billion worth of munitions were expended in the first two days alone, indicating a rapid burn rate of resources. The Center for Strategic and International Studies (CSIS) estimated the first 100 hours of Operation Epic Fury cost $3.7 billion, with most of these expenses unbudgeted. The conflict has escalated with a series of strikes and counter-strikes, raising fears of a broader regional confrontation in the Middle East and highlighting the enormous economic cost of modern warfare, especially considering long-term expenses like veteran healthcare and equipment replacement.
