Greece needs at least 50 billion more euros ($55 billion), including 36 billion euros from EU lenders, to stabilize its finances even under existing creditor plans, the IMF said Thursday.

In a new report on Greece's financing needs, the International Monetary Fund also cut the country's economic growth prospects for this year to zero percent from 2.5 percent previously forecast, in estimates that do not include the impact of this week's banking shutdown and capital controls.
