The Iranian rial fell to a record low against the U.S. dollar on the unofficial market on Sunday, a day after the U.S. President Donald Trump’s administration declared all United Nations sanctions on Tehran had been restored. The dollar was offered for as much as 273,000 rials, up from 267,800 rials on Saturday, according to foreign exchange site Bonbast.com, which tracks the unofficial market. Iran has dismissed the U.S. move as “void and illegal” and U.N. Secretary-General Antonio Guterres told the Security Council on Saturday he cannot take any action on the U.S. declaration because “there would appear to be uncertainty” on the issue.
