The currency crisis in Iran has become serious, the price of 1 million riyal is just 1 dollar, what is the reason?

Iran’s economy has been badly affected by international sanctions. The country’s economy has been severely affected, especially after the US’s decision to withdraw from the nuclear deal with Tehran in 2018. During the 2015 agreement, Iran greatly limited its uranium enrichment and storage in exchange for lifting international sanctions. At that time Rial was trading at 32,000 per dollar. After Trump was re -elected in January, the campaign to put “maximum pressure” on Iran started again, under which the country was banned. Trump again tightened the clamps on Iranian crude oil trade companies, including companies selling oil at a discount in China.
