The Euro came into being in 2002, replacing many national European currencies with a common currency. There are 16 members, with the largest economies being the Germans, French, Netherlands, Italy and Spain. The launch of the Euro was done successfully and it brought down transaction costs and financing costs across the Euro area, and was part of a broader movement of labor and services across the region (not as simple as the currency conversion, however).
The Euro was originally at around 80 cents to the dollar; it has gone as high as $1.50 to 1 USD and currently ranges around $1.30 – $1.40. This appreciation has been significant, caused both by policies that weakened the USD and strengthened the Euro.
While the Euro has been a successful currency and has brought benefits to the region’s economies, particularly the weakest economies (like Greece, Spain, Italy, Ireland, and Portugal, the “PIIGS”), recently the region has had difficulty with high budget deficits and the specter of outright default in these weaker countries.
While all parties benefit from having the Euro, some parties benefit more than others, and are “free riders” – particularly the weak Mediterranean countries that would never have such low financing costs and ability to easily raise funds in the bond markets without the implicit backstop of the German, French and Dutch treasuries.
