Kumar said that going by the initial results that have started coming in September, it seems that many banks are returning to profit.
"The major challenge which the banks - public sector more and some of the private sector banks (in India) - they have been facing is the asset quality challenge. For the last three years, it has been going on but as of now we are now on top of the situation on the NPA problem," Kumar told PTI in an interview in New York.
"In the power sector, the banks have still not been able to resolve the issues. But the Insolvency and Bankruptcy Code has helped the banks and at least now there is a solution available," he said.
Kumar added that the Insolvency and Bankruptcy Code has come as a "very good tool" in the hands of the banks and the financial creditors.
On the value of the rupee, which had this month fell below the 74 level compared to the dollar, Kumar said, "If the oil prices are stabilised, the exchange will also stabilise. Domestic inflation is not as much a cause of worry because it is very much well within the target that the Reserve Bank of India has set."
He said domestically, the economy continues to do well but the oil prices are the "major culprit" because that impacts the country's current account deficit in a big way and it puts pressure on the exchange rate.
