Buck up: Soros says dollar will remain world's go-to currency

One of the world's most influential investors has given the dollar a solid endorsement amid the market's ongoing seesaw between risk and risk aversion.

Billionaire investor George Soros said the dollar will remain the world's reserve currency for a while. "I think the dollar is the dominant currency for a while to come. But in the long run I think it would be important that the U.S. should be subject to the same discipline as the rest of the world," Soros told CNBC.
