New Delhi, Jun 16 : Confederation of Indian Industry (CII) said the Reserve Bank of India's decision to increase repo and reverse repo rates by 25 basis points each is on "expected lines" but hoped that there would not be further hikes in key rates amidst growing signs of slowdown in economic and investment activities. "Given the current rates of inflation, the RBI decision to increase headline rates by 25 basis points is on expected lines," CII Director General Chandrajit Banerjee said in a statement.However, he said the chamber hopes that that this is the last increase in rates as there have been growing signs of slowdown in economic and investment activities in the country.Current spell of inflation, being largely associated with supply-side bottlenecks and imported commodities, cannot be addressed by monetary tightening alone, he said, adding that even with as many as 10 upward revisions in policy rates since March 2010, there has been little respite on inflation.
