I've thought about this for a number of years now, but more so since the talk of a possible North American Union and it's "Amero" currency. The reason why the Euro is moving toward replacing the dollar, is not simply because of value, but because of it's wide spread usage. Before, the dollar competed with a multitude of European currencies, whereas now, it does not. Therefore global currency has become much like politics in this country. It's become a choice of Coke or Pepsi. Plus, the Euro is the currency for multiple nations while the dollar is basically used in one. I think this is why you see more chatter about a NAU & Amero. Some fear that the US could move to second fiddle. Personally, I couldn;t care less if we move to the back of the bus globally, as long as we are happy here at home. AP Greenspan: Euro Gains As Reserve Choice Monday September 17, 8:07 am ET Report: Former Fed Boss Says Euro Could Replace U.S. Dollar As Favored Reserve Currency FRANKFURT, Germany (AP) -- Former U.S. Federal Reserve chairman Alan Greenspan said it is possible that the euro could replace the U.S. dollar as the reserve currency of choice. According to an advance copy of an interview to be published in Thursday's edition of the German magazine Stern, Greenspan said that the dollar is still slightly ahead in its use as a reserve currency, but added that "it doesn't have all that much of an advantage" anymore. The euro has been soaring against the U.S. currency in recent weeks, hitting all-time high of $1.3927 last week as the dollar has fallen on turbulent market conditions stemming from the ongoing U.S. subprime crisis. The Fed meets this week and is expected to lower its benchmark interest rate from the current 5.25 percent. Greenspan said that at the end of 2006, some 25 percent of all currency reserves held by central banks were held in euros, compared to 66 percent for the U.S. dollar.
