Iran's central bank allowed trading in its currency at market levels after fixing the exchange rate in January as the threat of sanctions over the country's nuclear program and economic risks spurred Iranians to buy up dollars.
The bank on January 26 fixed the rate at 12,260 after the U.S. dollar surged to almost double that level in the unofficial currency markets.
