A further reduction of non-performing loans, financing the real economy and a digital transformation are the three main challenges facing Greek banks in 2019, a top executive in a systemic bank told the Athens-Macedonian News Agency (ANA) on Monday. The executive said that action to address all three challenges is underway and that the first positive results were already visible, while warning that there could be no complacency or any relaxation of efforts. He said that Greek banks were currently "midway" towards completing the huge task of reducing NPLs from 85 billion euro at present to 33 billion euro in 2021 and stressed that this reduction will be achieved through the sale and securitisation of loans (50 pct), auctions/liquidation of real estate property (25-30 pct) and debt settlement (20 pct). He noted that results so far were significant, given that NPLs totaled 107 billion euro in March 2016.
