don't have a ready made project on corporate banking ...but u can look towards "saturation of corporate banking in india"....
visit
Reserve Bank of India - India's Central Bank for the data on lending(credit) by banks and NBFCs and see the last 5-6years trend based on YoY basis and compare it with other sources of financing like ECB etc...
Based on the analysis you can suggest whether this segment moving towards saturation or not....
Hope that helps.....
