The Dollar Dilemma
A little bit of macro. The dollar is the reserve currency of the world. However as the US has been running huge trade deficits over the last decade or so central banks around the world, and particular in Asia, have been accumulating huge dollar reserves. These countries sell huge quantities of goods to the US and are paid in dollars. It is in each countries individual interest to diversify into other currencies by selling dollars. However, if all countries were to do this the value of the dollar would collapse as would the worth of their remaining dollar reserves. The lengthy post linked above looks at the role of this dilemma in the current financial crises. The actual dilemma is explained more succinctly in this letter to the Financial Times.
