Business and household deposits increased to 158.7 billion euros ($194.93 billion) from 155.7 billion in October, Bank of Greece data showed.
Greek banks have seen deposit inflows over the space of more than two years after the country clinched a third bailout to stay in the euro zone in July 2015.
Athens exited its latest bailout in August 2018 and now relies on bond markets to refinance its debt.
