Moody's Investors Service has said, RBI Governor Raghuram Rajan's policy of tight leash on inflation has showed results and Reserve Bank should continue with similar policies and communication going forward. Moody's Investors Service Senior VP Sovereign Risk Group Marie Diron said, credibility and effectiveness of monetary policy are factors which impact India's sovereign ratings. Moody's has a 'Baa3' rating on India, with a positive outlook. Talking to PTI Diron said in the last two years, India's inflation has fallen to more moderate levels, likely in part because of more credible monetary policy that has anchored inflation expectations. She said, they expect RBI to continue with similar policies and communication, showing commitment to achieve its inflation target. A monetary policy with tight leash on inflation is important especially in India, where in the past inflation has risen to very high levels, negatively affecting growth and investment prospects.
