I'm from Iceland and I speak from experience.
Your banks have absolutely no chance of surviving this. Once the pandora's box was opened it's all over.
The same happened in Iceland, and it took the banks a week to all go bust. But politicians kept saying they wouldn't. The state even lent the biggest and last bank to go bust a lot of money in that week to try to keep it a float, but it didn't do anything.
Once everybody consider the banks toast, they are. Even if you manage to raise enough money to solve current problem, it's not going to stop a run on the bank once they open, and they will eventually be run to the ground in a couple of days. All foreigners will instantly move their money out of Cyprus once the banks open, no matter what is said.
The only real solution to protect yourselves as a nation is to do two things:
1) move deposits to priority claims on the failed banks.
2) tax deposits beyond €100K before the banks go bust. Tax enough so that the state has enough money to pay out the €100K deposit guarantee.
This will ensure the state does not go bankrupt and ensure depositors get back maximum back in time.
