If they believe a major crash is coming, now is the best time to lay off 25% of your staff. But it also suggests that the Bank’s senior management believes the crash is coming fairly soon. If it is several years away and the severity is uncertain, one would not lay off so many people.
So when, I think when it is clear that the Greek government defaults and leaves the Euro. Maybe Russia will come to their aid.

You realize that even in crisis Greece has a higher GDP per capita than Russia right?
