"The broadbased recovery in the investment cycle is only expected to happen after FY20 as per our base case estimates due to moderate consumption demand outlook, weak pace of nominal growth recovery and global over capacity," domestic ratings agency India Ratings said.
The agency, a unit of global ratings agency Fitch, added that the corporates will shy away from investments despite the prevailing low interest rates.
Even as the government spending was up during FY16-17, there was a decline in the gross fixed capital formation in the same years, and the number has come down till 27.5 per cent in Q1FY18, it said.
"If private corporate spending in manufacturing or infra continues to deteriorate, it may have a moderating impact on the gross fixed capital formation," it warned.

It is essential for the overall capacity utilisation to go up to 85-90 per cent from the current 65-70 per cent for corporates to start spending, it said, adding this is unlikely in the next two years.
Release of the official data has also led to a rash of sharp cuts in growth estimates by the Reserve Bank of India, and also multilateral institutions like the IMF.
The government is mulling to revive economic fortunes through measures, which may include a stimulus. However, the agency raised doubts over the government efforts being effective in upping investments.
"Despite the higher government spending due to incremental revenues on account of GST, we believe government spending alone will have limited ability to revive the overall investment cycle unless there is a revival in corporate capex performance," it said.
Over 125 non-stressed corporates in the top-200 companies will invest the most, while the remaining 75 which find themselves classified as stressed will wait for their capacity utilisation rates to grow beyond 40 per cent before taking a call on investments, it said.
Sectors which will see investments will be oil and gas, auto and telecom, while the stressed infrastructure, metals and thermal and wind power will be reluctant.
The stressed sector will take over a decade to de-leverage and think about capacity utilisation, it said.
Ongoing mergers and acquisition and consolidation activity will also restrict fresh investments, it said.
Banks will also be unwilling to fund the investments because of problems on capital that they face, it said.
