Greek banks need 14 billion euros in capital even with a deal

ATHENS (Reuters) - Greece's banks will need an estimated 10 to 14 billion euros (7 to 10 billion pounds) of fresh capital to keep them afloat and more time before they reopen even if a deal is reached with European creditors on Sunday, a senior Greek banker told Reuters on Friday.

Shut for two weeks, banks have relied on an ECB-approved emergency credit line from the domestic central bank to dispense rationed cash and are hoping that they can be reopened by the end of next week, despite having bled more than 34 billion euros of deposits since December.
