How are exchange rates decided for each country?
Rates are arrived at by the cumulative buying and selling on the foreign exchange market, much the same way that stock prices are arrived at.  If there are more people wanting to buy dollars with euros, EUR/USD goes down.  If more people want to buy euros with dollars, then EUR/USD goes up. The initial rate was about $1.18 per euro when it began trading on January 1st, 1999.  It replaced the European Currency Unit at that time, which was a weighted basket of currencies of (more or less) the participating countries. You're correct about the printing press in the US and other countries.  The exchange rates do reflect in part how much of a relative workout those printing presses get.
