New Delhi : Prime Minister Manmohan Singh today said the downgrade of India's growth forecast by Moody's was a cause of concern but expressed hope that India would better last year's 6.5% economic growth.

"It is a cause of concern but one should not draw unwarranted conclusions," Singh told reporters when asked to comment on ratings agency Moody's analysis of the Indian economy.

Moody's research arm had scaled down its forecast for the country's economic growth this fiscal to 5.5% earlier this week.

However, Singh expressed hope that India would better last year's 6.5% of economic growth.

"The fundamentals of Indian economy are strong. Investments and savings are among the highest in the world.

I am hopeful, we will do still better than 6.5% growth performance of last year," the Prime Minister said.

Moody's Analytics had said India's GDP growth rate is likely to be 5.5% this year, while in 2013 growth is expected to be 6 per cent, adjusted from 6.2% earlier.

"There has been little policy response from either the Reserve Bank of India or the government and with global uncertainty dragging on, we see nothing on the horizon to lift the economy from its funk," Moody's Analytics Senior Economist Glenn Levine had said.
