A new United Nations report released on Tuesday calls for abandoning the U.S. dollar as the main global reserve currency, saying it has been unable to safeguard value.

"The dollar has proved not to be a stable store of value, which is a requisite for a stable reserve currency," the U.N. World Economic and Social Survey 2010 said.

The report says that developing countries have been hit by the loss of value of the U.S. dollar in recent years.
