The Iranian rial is the weakest currency in the world, with 1 rial buying a mere 0.000024 dollar (or, put another way, $1 equals 42,300 Iranian rials).

Iran’s currency has been squeezed by economic sanctions, including those the U.S. reimposed in 2018 and others the European Union has repeatedly imposed. Political unrest and an annual inflation rate that has been topping 40% are additional factors contributing to currency and economic weakness in Iran.

“Risks to Iran’s economic outlook remain significant,” the World Bank concludes.
