A widely-anticipated cut in interest rates by the Reserve Bank of India (RBI) on Friday is unlikely to get markets too excited. But what the central bank says just might, economists told CNBC.

The RBI is tipped to lower its key repo rate by 25 basis points to 7.25 percent to boost a weak economy, a move that would come in a week where the European Central Bank lowered interest rates by 25 basis points and the U.S. Federal Reserve has held fast to its commitment to maintain aggressive monetary stimulus.
