"We forecast fiscal (deficit), inflation and infrastructure metrics to remain weaker than the median for similarly rated peers.
"While stronger growth in this large and diverse economy will help counterbalance these credit challenges, they limit further upward momentum in the sovereign rating," Moody's Investors Service said in a note issued from Singapore.
The comments come days after the government released the Q1 GDP numbers at 5.7 per cent and CAD at 1.7 per cent of GDP.
Inflation measured by consumer price index continues to skirt around the 8 per cent mark, with upward pressures being exerted by food prices due to weak monsoon.
The agency, which has a 'Baa3' rating with a stable outlook on the country, said the 5.7 per cent GDP print in the April-June period is in line with its "long-held view that growth deceleration to sub-5 per cent levels over the past two years would reverse over time."
Moody's said the higher growth numbers in Q1 will help improve tax revenues and capital flows into the country, and can also help reverse the weakening metrics that have occurred in the fiscal and external position in recent years.
Additionally, Moody's said the macroeconomic outlook will improve if the government is able to "implement policies that ease inflationary pressures and increase infrastructure investment".
After the release of official data pointing to a 5.7 per cent jump during the first quarter, coming after two consecutive fiscals of sub-5 per cent growth, Finance Secretary Arvind Mayaram had said that he expects some positive action from the international rating agencies.
