Planning Commission today pitched for lowering of interest rate to boost economic growth which is beginning to look up after moderating to 5.4 per cent in the first half of the current fiscal. While commenting on Reserve Bank's mid-quarter review, Plan panel Deputy Chairman Montek SinghAhluwalia said, over a longer period of time, steps are needed to bring down the interest rate. He said, RBI looks at these things independently and Planning Commission should give them freedom to decide about interest rates. RBI has chosen to keep all key rates and ratios unchanged in its policy review unveiled earlier in the day.Mr Ahluwalia said that the deceleration in growth has bottomed out and the second half would be better . He said the economy is beginning to turn around and everybody should support the revival of growth. On the Finance Ministry's economic growth projection of 5.7-5.9 per cent in its Mid-Year Economic Analysis, he said, that it is reasonable assumption. The Finance Ministry in March had projected a growth rate of 7.6 per cent for the current fiscal.
