Greek banks will remain closed until July 6 -- the day after a referendum on bailout proposals -- and ATM withdrawals will be limited to 60 euros ($65) a day in the same period, according to an official decree published early Monday.

The decree on capital controls, published in the official government gazette and entitled "Bank Holiday break", lists the measures imposed on financial institutions lasting from June 28 to July 6 and was signed by President Prokopis Pavlopoulos and Prime Minister Alexis Tsipras.

It cited "the extremely urgent and unforeseen need to protect the Greek financial system and the Greek economy due to the lack of liquidity caused by the Eurogroup's decision on June 27 to refuse the extension of the loan agreement with Greece".
