The value of the US dollar, for the most part, is dependent on how much money is in circulation in the US. Lets say there are $500M USD in circulation in the US, and $1USD = $1AUD. If we print off another $500M USD, making the total USD in circulation $1B, then the exchange rate would theoretically be at $1USD = $0.50AUD.
The Federal Reserve Bank (the Fed) is in charge of the monies in the US. They decide how much money is in circulation by buying and selling government securities. Colin
