Information that the release of Greece from the EU will inevitably negatively affect the credit rating of almost all countries of the European Union was announced by the official representative of the International rating agency Moody’s. As it was explained — the release of Greece from the eurozone will become the failed fact of the financial losses of those who once decided to provide financial assistance to this country, investing money in Greek debt obligations. These losses will be suffered both directly, due to denomination, and indirectly due to quite serious macroeconomic difficulties that will inevitably follow. Just, as economists note, the exit of Greece from the eurozone will also become a threat to the integrity of the European Union as a whole and a single European currency in particular.
