While several committees have examined and suggested ways to improve corporate governance in banks in India, this study makes an attempt to prepare a benchmark index for the board composition aspect of corporate governance. A comparison between the indices for public sector banks with private sector banks reveals that differences in governance structures cannot be explained fully in terms of ownership only. This is a welcome feature, as with some efforts on the part of the majority shareholder, corporate governance in all the banks can be brought on par with the best-performing bank, by ensuring greater compliance with corporate governance benchmarks.
