Banks in Greece will be closed until 6 July and ATMs will reopen late Monday with a daily withdrawal limit of €60.
This news came as a result of the European Central Bank (ECB) saying they will not increase emergency funding to Greece.
Greece is currently struggling to pay money it has borrowed from the International Monetary Fund (IMF).
Over the last few weeks MPs from Greece and various European countries have been discussing a bailout agreement. However, no agreement had been reached.
If Greece is unable to pay the money back this could cause huge problems for the country. They may even be forced out of the Eurozone – the countries that use the Euro as currency.
