Four Greek banks have received 18 billion euros ($US22.6 billion) as part of the nation's last international bailout. The funds will be divided between National Bank, Alpha, Eurobank and Piraeus Bank.
The BBC reports the money has been released by the European Financial Stability Fund to a Greek agency in charge of distributing the funds.
It is part of Greece's second bailout by the European Union and the IMF in March. The deal was for 130 billion euros and hinged on an agreement by Europe's major banks and other financial institutions to write-off a large part of their loans to Greece.
Greek banks are unable to raise money on the international markets, and are relying on the European Central Bank and bailouts from the EU and IMF.
