That would be wonderful, no doubt. But I think government will list them in both ( NSE IFSC and in BSE INX) as REC did.
Regulatory compliance was pretty bad in the past and that lead to the pro NSE stand by the authorities. But looks like things are changing in favour of BSE ( Interoperability for example). From Monday interoperability in derivatives also kicking in. I do really hope that BSE picks up volume in derivatives.
Today INX did a record high turnover today. For the first time INX crossed 4 Billion turnover and its 4.8 Billion dollar so far.
