- The Reserve Bank of India is the central banking institution that controls the monetary policy of the Indian rupee. It releases various reports, but the 'Ecowrap' is not one of them.

- Option 2 - HDFC Bank

- HDFC Bank is a major private sector bank in India. While it conducts economic analyses, it is not known for publishing the 'Ecowrap report.'
