Where did the Greek cash go? Apparently (1, 2) Greece is running out of cash right now. I am wondering where the cash went.
One option that I can image is people withdrawing funds and taking them out of the country but this cannot be the core of the problem, can it?
The other possibility would be people just withdrawing money and saving it but eventually the money will have to be spend because people need to buy things so the problem might solve itself?
What am I missing here?
Relaying from @lumi's answer to this question (not a duplicate though) we see that



As @lumi writes 


  ..."if we look at the Greek money supply figures, and we know that that there are essentially three ways for liability deposits to
  decrease as shown - loan repayment, loan write-off and cash
  withdrawals, we can deduce pretty easily that Greece is experiencing a
  massive outflow of cash. We can assume that some of it is cash
  withdrawals particularly recently, but some of it also debt repayment
  to debt owners outside of the Greek banking system."


For the last months, I would increase a bit the emphasis on "people withdrawing funds and taking them out of the country".
