For starters, Marinopoulos has over 1,3 BEUR in liabilities, i. e. money which they owe to someone else. One might say ok, so the banks will have to take a loss but that’s their problem because they made bad loans. When 4 banks have to take losses of over 500 MEUR, that may quickly turn out to be not only the banks‘ problem but someone else’s, too.
Marinopoulos owes over 700 MEUR to trade creditors. Now the bullets are starting to hit closer to home because the reverse conclusion is that trade creditors may lose over 700 MEUR. Huge amounts of money are owed to individual large suppliers which raises the question how those suppliers will handle those losses and whether, perhaps, there will be another chain reaction among the suppliers and their creditors. But then there are also an assumed 3.000 small suppliers, perhaps even your small neighborhood farmer, who might be entirely wiped out by their losses.
Taken in sum, a Mariopoulos bankruptcy would cause shock waves throughout the Greek economy whose final impact can only be guessed at this point. And then the next question is: Will there perhaps be another Marinopoulos soon?
