(Bloomberg) --

Iran’s national currency stumbled to record-low levels after renewed efforts to revive the country’s beleaguered nuclear deal failed to make progress.

The U.S. dollar crossed 300,000 Iranian rials in open market on Saturday, according to two local exchange shops and media reports. The level was last seen in October 2020, when the rial crashed to record-low prices against the dollar.

Four traders at a currency exchange hub in central Tehran said on the phone that they weren’t selling the dollar on Saturday, citing market volatility.
