Since the 1979 revolution, the United States has not provided direct financial aid to Iran. Instead, economic sanctions have been the primary tool, restricting trade, banking, and investment. The 2015 Joint Comprehensive Plan of Action (JCPOA) temporarily lifted some sanctions in exchange for nuclear limits, but the U.S. withdrew in 2018 and reimposed penalties. These measures have severely impacted Iran's economy, causing inflation and reduced oil exports. No credible reports indicate any U.S. monetary assistance to Iran in recent years.
