To the extent that the United States has, I don't like the word hegemony, the United States has influence around the world, I don't think that's based on to any significant degree on the fact that countries use the dollar as their major reserve.
The reserve currency role seems to add prestige to an area and some people in Europe have talked about the desirability of the euro becoming an international reserve currency.
The dollar went up some eighty percent in real terms as I recall now or something like that - from '80 to '85.
Today we have so much more flow of private capital that most international imbalances are financed that way, by private capital movements.
So you can be pretty sure that central banks around the world will not start dumping dollars on the market in order to buy euros.
The dollar is the main private currency for investment purposes, for transactions purposes, as a vehicle currency as it's called.
The dollar performs internationally all three functions of money, as a medium of exchange, a unit of account and a standard of value.
