The Indian economy had grown by 7.3 per cent in 2015-16, Moody's said adding private investment remains weak.
"India, as a net importer of commodities, has benefited from falling prices and growth will be driven by rising consumption. However, a sustained improvement in domestic private investment would be required for the growth momentum to be sustained," Moody's said in its Global Macro Outlook 2016-17.
Modest exposure to trade in goods and a net-commodity importing status has to some extent shielded the Indian economy from external headwinds.
"Weak global growth has meant a 9 per cent year-over-year decline in total exports in real terms in 2015Q4, after declining by an average annual rate of 5.6 per cent in the first three quarters of 2015," it said.

Also, investment spending fell in the last quarter of 2015, as did industrial production, and capital utilisation rates remain low.
"The prevailing low headline inflation is expected to remain so, given the current forecast of a good monsoon season, and should allow the Reserve Bank of India to sustain its current accommodative stance," Moody's said.
It expected the Indian economy to continue to grow close to an annual rate of 7.5 per cent in real terms in 2016 and 2017, largely driven by private consumption growth.
"Private spending will be supported by the implementation of the public sector salary increases, mandated by the 7th Pay Commission, and a rise in rural incomes, provided the forecast of a good monsoon is realised," said.
"Combined with the fact that external demand is likely to remain lackluster, a sustained improvement in domestic private investment would be required for the growth momentum to be sustained," it said.
Expecting emerging economies to continue to be a drag on
G20 growth, Moody's revised downward 2016 growth forecasts for Argentina, Brazil, Mexico and Turkey, as well as 2017 growth forecasts for Brazil, Mexico, South Africa and Turkey.
"We continue to expect that emerging markets growth will stabilize and strengthen going into 2017, as the impact of the 2015 terms of trade shocks from lower commodity prices starts to fade," it said.
It maintained expectation of Chinese economy gradually slowing down to around 6.3 per cent in 2016 from 6.9 per cent in 2015, with significant fiscal and monetary policy support.
"Downside risks to China's growth outlook persist, especially if policy support becomes less effective as leverage continues to rise. The knock-on effect on global growth would be significant," it said.
For G20 advanced markets, Moody's forecast growth of 1.7 per cent for 2016 compared with 1.9 per cent in 2015.
"As a result, we now expect slightly slower growth over the next two years in Canada, Italy, Japan, the UK and the US, although forecast revisions are generally small. We currently expect G20 advanced markets growth at 1.7 per cent for 2016 and 1.9 per cent for 2017, compared to 1.9 per cent in 2015," it said.
Stating that financial markets volatility has subsided relative to the start of the year and capital flows to emerging markets have started to return, Moody's said the risks that caused the volatility remain under the surface.
Moody's said it expects oil prices to remain low over the next two years.
Despite the recent improvement in the price of oil, to some extent related to weakness in the value of the US dollar, persistent supply and demand gap globally remains, it said sticking to its earlier forecast of average oil price of around USD 33 per barrel in 2016 and USD 38 per barrel in 2017.
