From 2019 to 2020，The Iranian economy faced an unprecedented severe crisis once again. Since the Trump Government withdrew out of the JCPOA in 2018，the US has implemented a series of sanctions on Iran，known as “Extreme Pressure” to force nearly all of countries to give up economic ties with Iran. Iran’s oil production and export has been under the heavy blow，import and export trade shrink greatly，while the inflation is very high，the exchange rate is falling，and the employment is also very weak. In 2020，Iran has been the worst-hit country in the Middle East by COVID-19，casting more shadow over its economic development. Iran’s economy is now in its third year of negative growth. In order to counter the crisis，the Iranian government has taken some measures to boost the economy，which has led to the development of local manufacturing industry and the steady increase of agricultural self-sufficiency. But even if the epidemic ends，the fundamental problems facing Iran’s economy—external sanctions and internal structural obstacles—cannot be properly addressed under the existing regime. The outlook for Iran’s economy is grim.
