a "No" vote might persuade the ECB to demand additional collateral from banks to cover the risk of losses on the 120bn euros in emergency lending it and the Bank of Greece have already provided. This would be very painful for the banks. Right now they have unencumbered assets sufficient to borrow an additional 17bn to 20bn euros from the Bank of Greece, if the ELA ceiling were lifted. But if the ECB decided these assets - such as loans to Greek companies - are intrinsically less valuable than it currently thinks, and imposed a bigger so-called haircut on these loans, that 17bn to 20bn of possible additional credit could shrink to zero or a negative number.

A report released Thursday by the IMF said the European Union may need to take losses of 53 billion euros on money it has lent to Greece. At loggerheads with its international creditors, Greece jumped at the opportunity, at the risk of relying on the recommendations of an institution it loathes. Embracing key proposals in the report, Greek Prime Minister Alexis Tsipras demanded Friday that creditors forgive a third of the country's debt and allow delayed repayments for the rest. Much is at stake for Greece's EU partners. They are the main contributors to Greece's successive bailouts, and hold 211 billion euros out of a total of about 280 billion euros that Greece owes. Of all Greece's creditors, the Europeans are the most heavily exposed to losses.
