Hoping that the Non-performing asset (NPA) situation will improve in the coming quarters, Finance Minister Arun Jaitley today said an all-out effort has been launched to correct the current "unacceptable" level of bad loans in the PSU banks. He said, the banks reached this level partly because of indiscretion, partly because of inaction, partly because of challenges in some sectors of the economy. <br/><br/>Jaitley was inaugurating 109 new branches and 109 Bunch Note Acceptors (BNA) on the Indian Bank Foundation Day in New Delhi. The Finance Minister said the government's plan to infuse capital into the PSU banks over the next four years will "infuse lot of financial strength" in these banks to deal with the bad loan problems.<br/><br/>Gross Non Performing Assets (NPAs) of public sector unit (PSU) banks at the end of March quarter stood at 5.20 per cent compared with 5.63 per cent in December.
