The dollar has been in the dumps for weeks now, and even Thursday night's coordinated action to weaken the yen failed to lift the dollar against other currencies. Is the dollar losing its safe-haven status? And how should you trade it?
Barry Eichengreen, a professor of economics and political science at the University of California Berkeley, believes that there is no longer a logical reason for the dollar to be the world's only reserve currency.
"I think it simply makes no sense for the dollar to be the only global currency when the United States is only 20% of the world economy," he said on CNBC's "Money In Motion."
Eichengreen thinks the euro could be a global currency in five years, and he said he takes at face value the Chinese government's plan to internationalize their currency by 2020.
