"Interest rates are not the only reason why investment is not happening. We need a much more enabling environment for industry, for growth, and interest rates are one criteria which is a deterrent," Kidwai said on the sidelines of a water conservation conference here last week.
Retail inflation easing to a 25-month low of 8.1 per cent in February and a slight improvement in industrial growth have raised hopes for a rate cut by RBI in its monetary policy scheduled on April 1 to boost economic activity.
Inflation fell to nine-month low of 4.68 per cent in February due to easing prices of kitchen staples like onion and potato.
