Uh... if you pay 1% or less a year in interest as they in USA. Many Cyprus banks were paying north of 5% a year so they'd have to make maybe 7%-10% a year to break even after expenses and taxes.
8. You never, ever, ever, hit insured depositors.
Great point, expect that no one is touching them. Deposits over EUR 100K are being hit /frozen, those up to EUR 100K are not touched, which just happened to be the insured amount. The banks could have bought private insurance and threatened to take down the next AIG with them (Now that's leverage), but they apparently didn't.
The real fault lies with the banks and Cyprus gov (or the people, indirectly). They could have cracked down on these shady deals and limited the bank's exposures to Greek debt. They didn't and Germans /N Europeans don't want to ask their taxpayers to bail another country. Someone has to pay, it clearly can't be the taxpayers given the ratio to GDP so it's the depositors and bank owners. To summarize:
There is no money.
No one wants to give them more money.
Banks are broke and as usual you can lose all the money that is not insured. It says so, or it should say so on the tiny print.
