"We expect sustained robust growth in the US, Britain and India over the next two years," Moody's Investors Service said in its quarterly Global Macro Outlook report issued in London.
The agency has a "Baa3" rating with a stable outlook on India, which is the lowest in the investment grade.
Its peers S&P and Fitch had flagged concerns over falling growth, high inflation, the high fiscal and current account deficits and a sense of 'political paralysis', among other factors and had also threatened to downgrade the country to junk status.
In an earlier note, Moody's had said it expected GDP growth to touch 5 per cent in 2014 and accelerate in 2015. The country had two consecutive fiscals of sub-5 per cent growth, and the prospects have been looking up since the June quarter, when GDP growth accelerated to 5.7 per cent.
However, there are concerns that the number will slip to around 5 per cent due to a weak industrial growth. RBI Governor Raghuram Rajan had called the process of recovery as "uneven".
