The Eurogroup of finance ministers considered the request during a 90-minute conference call Tuesday night. The group expect another proposal from Athens by Wednesday morning, Estonian finance minister Sven Sester said in a tweet. Eurogroup head Jeroen Dijsselbloem offered a withering appraisal of Tsipras' offer on CNN soon after the call ended. "The political circumstances and political stunts of the Greek government don't seem to have changed," he said. "The practical circumstance is that the old program expires" at midnight. The rejection makes it all but certain that Greece will default on a €1.6 billion loan repayment to the International Monetary Fund due by midnight Tuesday. A default sets a series of levers in motion that is likely to result in Greece leaving the euro. The default will put immediate pressure on the European Central Bank to reconsider its support for Greek banks.
