How will businesses pay salary?
Your banks are effectively toast. Being able to withdraw €300 from your deposits says nothing. Your banks have defaulted on their promises, they are in a state of default, they are bankrupt. In reality they should be put into bankruptcy, closed.
Banks can't just tell depositors their money is gone and keep operating like normal.
Someone who has lost money will sue, that's for sure. Your judiciary system will be flooded with lawsuits.
You've yet to see the fallout from this. Banks who negate on their promises can't just operate like nothing happened, nobody will do business with them, and banks rely on others doing business with them, they rely on others trusting them.
Small depositors are not the problem, we're taking about large scale financial transactions here, for industry, for businesses, so your economy can operate. E.g. a industry needs to import raw materials from overseas, the seller wants bank guarantees of payment, but not from a Cypriot bank, and the Cypriot industry is unable to provide other type of guarantees, hence has to pay in cash. The cost of insuring Cypriot debt will increase.
In all likelihood, what we will see unfolding for the next weeks is a domino effect on the Cypriot economy. Businesses will go bankrupt because of the banks, and the whole "casino" economy will unravel.
But other than that, you can withdraw €300 (cypriot) euros, which seems to be another currency than the euro.
