She added that long-term investors like insurance companies and pension funds are not able to take part in the about Rs 20 trillion corporate bond market as they are required to invest only in higher-rated paper.
Bhattacharya was replying to a question on the steps taken by RBI late last month to deepen the bond market which has not really taken off as desired due to a host of factors such as lower market depth, absence of a hedging mechanism and lack of a variety of debt instruments entering the market.
Even after working on to deepen the market for the past decade or so by the central bank and regulator Sebi, it is only about Rs 20 trillion in size, which is only a fraction of the Government securities market.

Bhattacharya, however, exuded confidence that over time, as people understand the risks and as the resolution of stressed assets becomes faster, investors will get more confidence of putting money into lower rated credit instruments as well.
Among other measures, the Reserve Bank had permitted banks to increase the partial credit enhancement given to banks to 50 per cent from the earlier 20 per cent. It also took more steps towards accepting corporate bonds under the liquidity adjustment facility and also permitted brokers in it.
