"The Rabi crop is likely to be good one. That will help bring inflation down. So as inflation comes down, there is case for RBI to cut interest rate. I think, we have a case for stronger growth," Rajan said at an event here.Wholesale Price Index (WPI) for the month ended March moderated to three-year low of 5.96 per cent against Reserve Bank's projection of 6.8 per cent.
In its last policy review in March, RBI slashed short-term lending rate by 0.25 per cent to 7.5 per cent.
Accordingly, the short-term borrowing rate came down to 6.5 per cent. However, the Cash Reserve Ratio was retained at 4 per cent on expectation that government will start spending more.
India's economic growth has slowed to a decade low of 5 per cent in 2012-13. The third quarter of the financial year saw the growth plummeting to almost a four-year low of 4.5 per cent.
Replying to a query whether retrospective amendments create negative sentiment, Rajan said: "In general, the government should avoid doing retrospective amendments, which Parthasarthi Shome committee report has suggested."
Former finance minister Pranab Mukherjee in his 2012-13 budget has brought amendment to Income Tax Act, 1961 with retrospective effect to undo the Supreme Court judgement that was ruled in favour of Vodafone.
Vodafone is facing the tax liability for purchase of Hongkong-based Hutchison Whampoa's stake in Indian telecom business Hutchison Essar in 2007.
