Global rating agency, Standard and Poor's (S&P), in its recent report said that India could be the first BRIC nation to falter and fall below investment grade in the ratings. In a chat with NDTV Profit's Devina Menon, Keki Mistry, Managing Director, Housing Development Finance Corporation Ltd. (HDFC) said that it is a warning and they haven't yet downgraded India's rating. "We should start looking at lower interest rates to boost growth," he said.
