That’s why confidence is so important. The Heads of State or Government wanted to remove all ambiguity, and in their own words they said: “All other euro countries solemnly reaffirm their inflexible determination to honour fully their own individual sovereign signature.
The euro area Heads of State or Government fully support this determination, as the credibility of all their sovereign signatures is a decisive element for ensuring financial stability in the euro area as a whole”. I could not have put it better myself. Did you look into the possibility of Greece leaving the euro? Not for a minute did anyone consider that option.
