經濟制裁
Economic sanctions against Iran, such as the embargo against Iranian crude oil, have injured the economy. In 2015, Iran and the P5+1 reached a deal on the nuclear program that removed the main sanctions pertaining to Iran's nuclear program by 2016. According to the BBC, renewed U.S. sanctions against Iran "have led to a sharp downturn in Iran's economy, pushing the value of its currency to record lows, quadrupling its annual inflation rate, driving away foreign investors, and triggering protests."
