According to Bloomberg:
The dollar’s role in international trade should be reduced by establishing a new currency to protect emerging markets from the “confidence game” of financial speculation, the United Nations said.
UN countries should agree on the creation of a global reserve bank to issue the currency and to monitor the national exchange rates of its members, the Geneva-based UN Conference on Trade and Development said today in a report.
I’m not sure that ditching a national monetary policy is the best course of action for the United States. Nor do I think the American people support forfeiting their monetary sovereignty to the “global community.”
Milton Friedman has this to say about a global currency:
I view it as a monstrosity—on a par with my reaction to world government, for that is what a common currency amounts to for one aspect of economic activity. As a citizen of the United States, I find it bad enough that we have developed monetary arrangements under which so much power has been vested in a small group of unelected individuals, subject only indirectly to political control. I find it far worse to vest so much power in individuals chosen by international negotiation, individuals who are not accountable in any meaningful way at the ballot box.
