Mr Regling said: “The EFSF is Greece’s biggest creditor. This event of default is cause for deep concern. It breaks the commitment made by Greece to honour its financial obligations to all its creditors, and it opens the door to severe consequences for the Greek economy and the Greek people. The EFSF will closely coordinate with the euro area Member States, the European Commission, and the IMF on its future actions.”

The EFSF loans concerned are €109.1 billion under the Master Financial Assistance Facility Agreement, €5.5 billion under the Bond Interest Facility Agreement and €30 billion under Private Sector Involvement Facility Agreement.
