German institutes say Greece needs another "haircut"
Asked whether investors in Greek debt would need to accept another haircut, or reduction in the value of their holdings, Joachim Scheide, head of forecasting at Kiel-based IfW institute, said: "Yes, we don't think Greece can be saved."
The International Monetary Fund wants official lenders such as Germany to take a "haircut" along the lines private bondholders already swallowed earlier this year.
