Currencies Keep Climbing

Foreign exchange rates in the unofficial market extended weeklong gains against the rial hitting fresh highs on Thursday. 
The dollar was traded at as high as 308,000 rials posting more than 3% rise from the day before. Triggered by inflation expectations, the American currency has gained more than 8% in one week.   
The Central Bank of Iran says the new market volatility is driven more by excitement and inflation expectations rather than fundamental market factors, such as insufficient supply.
