The European Central Bank is making preparations again for a Greek exit from the euro, according to the German news magazine Der Spiegel.
The article so far is light on detail.
Here is a rough English translation from the piece:
The European Central Bank (ECB) is preparing for a Greek exit from the monetary union ... Information obtained by SPIEGEL, an internal simulation games how the rest of the eurozone could be held together.
This comes just a day after another German media source said the ECB wanted capital controls to be brought in to halt any potential capital flight from Greece. The piece suggested the governing council of the central bank favoured the move, but the ECB denied it had even been discussed.
