Germany: Euro zone can handle it if Greece leaves

"The German government believes that the euro zone would now be able to cope with a Greece exit if that proved to be necessary, Der Spiegel news magazine reported on Saturday, citing unnamed government sources."

Both Chancellor Angela Merkel and Finance Minister Wolfgang Schaeuble believe the euro zone has implemented enough reforms since the height of the regional crisis in 2012 to make a potential Greece exit manageable, Der Spiegel reported.

"The danger of contagion is limited because Portugal and Ireland are considered rehabilitated," the weekly news magazine quoted one government source saying.

In addition, the European Stability Mechanism (ESM), the euro zone's bailout fund, is an "effective" rescue mechanism and was now available, another source added.

Major banks would be protected by the banking union.
