Speaking at the India Economic Summit, he said that huge private investment during the last five years has created a lot of surplus capacity.
"I think we are quickly reaching the point where that surplus capacity will get consumed in various sectors in the country ... My own view is that it will take another year at least for the private sector to start re-investing," he said.
Speaking at the session on auto sector moving from BS IV to BS VI emission norms, Kant said lot of investments are being done by both public and private sector.
Talking about electric vehicles, he said price of batteries will dip from USD 273 to USD 73 and that will be the point when electric vehicles will take off.
"We are working closely with the auto industry," he said, adding the industry would be given adequate time to reap the advantages of investments that has been made for BS VI.
Sumit Sawhney, country CEO and MD Groupe Renault India said that it was a big stress moving from BS IV to BS VI which took Europe 11 years. "We are practically moving in three years now".
"There was a huge disparity because international players like us have to come to India and actually downsize our technologies to meet the local requirements. So I think its a catching up for domestic players and international manufacturers. We have that technology," he said.
Earlier speaking to reporters, industrialist Ajit Gulabchand said, "if you bring back the joy to do business, private investments will come."
He also said that tax levels has to come down for the corporate world.
"We need a substantial reduction in line with east Asian countries," he said, adding "I am not in favour of stimulus as it is not easy."
Gulabchand also made a case for drastic rate cut by the Reserve Bank of India (RBI).
Speaking at another session, Keiko Honda, Executive Vice-President and Chief Executive Officer, Multilateral Investment Guarantee Agency (MIGA) said that although India is a low risk country, foreign investor is looking for the availability of investible projects which is more of a problem than scarcity of capital.
She further said that the private sector should mitigate risks through taking recourse to MIGA.
