A so-called Grexit or Greek exit from the eurozone is a possibility but would not signify an end to the single currency, International Monetary Fund chief Christine Lagarde said in a newspaper interview Thursday.

"A Greek exit is a possibility," Lagarde told the daily Frankfurter Allgemeine Zeitung. Such a scenario would not be "a walk in the park" for the single currency area, but would "probably not be an end to the euro," she said.
