Iran’s Central Bank has allowed money exchange offices to resume work after a ban imposed in March. The bank’s governor, Abdolnasser Hemmati, said on Sunday that “money exchangers are allowed to sell and buy foreign currencies” once again. He also said that legal institutions and businesses will again be allowed to bring gold and foreign currencies into Iran, AP reports. Hemmati said the decision will go into effect on Tuesday. The official rate will remain at 42,000 rials to the dollar for vital imports such as medicine and food.
