Cypriots don't seem to like Mondays, next week there will be another holiday. All banks being closed until Tuesday will affect companys. It won't affect confidence in banks though, since it just cannot get worse. The people can get some money so they won't be all cash-strapped.
Still, there are only rumors over a Russian involvement as of now, so we don't know if there is a viable plan B. I think some of the banks will not survive this though. Cyprus has to take steps to regain some confidence in the banking system. Mergers and a bad bank might help. Also the current owners have to be wiped out. A new bank under new management will have the chance to survive. The FDIC can handle this in such a short timeframe. So I hope this could be a first case where the ECB steps up to that.
Sadly a disorderly bankruptcy of the country is not off the table just yet. Tomorrow will bring some clarity as the president Anastasiades will then announce if he has a new plan and how it should work.
