The assessment showed that Greece's banks need 14.4 billion euros ($15.85 billion) of fresh capital.
"The European Commission takes note of the results of the comprehensive assessment of the four main banks in Greece, as published today by the European Central Bank," a Commission spokesperson said.
"We are encouraged by these results. This is an important step in the implementation of the three-year Greek program under the European Stability Mechanism," it said.
"The bank recapitalization process is an integral part of the efforts by Greece and its partners to restore confidence in the banking sector, so that capital controls can be gradually removed and affordable lending to the economy can resume," it said.
