Greece

What will happen to the eur-usd if and when Greece decides to exit the euro. I really don’t have a clue. What do you think?

I don’t have a clue either but my guess is, it will go sharply down and then slowly up

I don’t think they will decide to leave the Euro, when they can stay in and be bailed out.
The important question- What will happen when/if they default, and if they drag down any other countries in the process. It depends on the up-coming elections, although the ruling party want elections suspended until austerity measures are in place.
I’d agree with yunny1, the potential is there for sharp declines in the Euro.
