The trend is expected to be reversed through the recapitalization plan which is regarded as the key change the Greek banking system needs to undergo in order to come out of the crisis.
Part of the international financial aid will be distributed to the Greek banking sector in two ways, Provopoulos said.
First, part of it will be used to recapitalize the four biggest banks. The country's four largest lenders have already received an 18 billion euros (23.3 billion dollars) boost in May.
The remaining funds will be used to help weaker banking institutions in which shareholders will be unable to put the extra capital, he noted.
Provopoulos said he was confident the Greek banking sector, and along with Greece and the Greek people, would overcome the current challenges and return to prosperity.
"Despite the changing landscape in the Greek banking sector, not a single depositor lost even one euro," Provopoulos stressed.
