VIII - ESM Treaty

The European Stability Mechanism (ESM) Treaty was signed on July 11 2011. It was later renegotiated and a new ESM Treaty was signed on February 2, 2012. The Treaty provides a permanent emergency fund that is intended to succeed the temporary emergency funds. It entered into force on September 27, 2012 for 16 contracting parties (Estonia completed ratification on October 3). The 17 contracting parties are the member states of the Eurozone, but the ESM Treaty is concluded outside EU law.
