Europe's Central Bank Issues Cyprus Ultimatum

People line up at an ATM in Nicosia to withdraw cash on Thursday.

The clock is ticking on Cyprus' fiscal cliff.

The European Central Bank has given the Mediterranean country just four days to come up with its own bailout plan, or a eurozone lifeline to its struggling banks will be severed.

The ultimatum comes after Cypriot lawmakers on Tuesday rejected a highly unpopular proposal put forward by the European Central bank, the European Commission and the International Monetary Fund to give the country's banks half of a $13 billion bailout package if they can raise the other half from a steep levy on the country's personal savings accounts.

Since then, the Cyprus government has been struggling to come up with a "Plan B" that will satisfy international lenders. If Cyprus can't do it by Monday, the ECB will pull the plug on Cypriot banks, which would likely precipitate a collapse of the island's financial institutions and send shock waves through European and world markets.
