When euro was first launched 10 years ago, it was set at the rate of EUR 1.00 = USD 1.10. Since then its exchange rate has been swinging between USD 0.80 and USD 1.60.
In recent years it's been relative strong to US dollars and is now valued at about EUR 1.00 = USD 1.3560.
But with the debt crisis of several European countries, namely PIIGS, the euro is set to go sharply down. It's very likely that we would see euro go back to the initial exchange rate of EUR 1.00 = USD 1.10 by the end of this round of selling down.
Or down to around EUR1.20 if chart tells anything.
