Greece could not exit euro without leaving EU

If Greece decided to leave the euro, it would also have to quit the European Union, according to the terms of the EU's treaties, the European Commission said on Thursday.

“"The treaties indeed confirm what we have been saying here: the treaty doesn't foresee an exit from the euro zone without exiting the EU, so indeed that is the current situation," European Commission spokeswoman Karolina Kottova said.

The comment was in response to a question about the provisions the EU treaties make for a country to leave the euro, but the spokeswoman did not refer to a particular member state.”
