NSE Shares on NSE: What Does It Mean for BSE?

NSE is reportedly considering allowing its own shares to trade on the NSE platform under the “permitted-to-trade” category, even though the formal listing would remain on BSE. The proposal has already raised concerns about its impact on BSE. For BSE, the biggest potential loss would be in trading revenue and liquidity. If investors prefer trading NSE shares on NSE, part of the trading volume that would otherwise come exclusively to BSE could shift to NSE. This could reduce BSE’s benefit from hosting NSE’s shares and potentially weaken investor interest in BSE. However, it does not mean BSE would lose all the benefits. Since NSE would formally remain listed on BSE, BSE would still be the primary listing venue, and the stock would continue to contribute to BSE’s ecosystem. The bigger concern is market integrity. Allowing an exchange to trade its own shares creates a potential conflict of interest because NSE would simultaneously operate the trading platform and have an economic interest in the security being traded. This could raise questions around price discovery, surveillance, order matching and equal treatment of investors. That does not automatically mean manipulation or mistrading will occur. Strong SEBI oversight, independent surveillance and transparent rules would be essential to prevent any misuse. Overall, the move could be negative for BSE’s trading revenue but positive for NSE’s liquidity and investor accessibility. The key issue will be whether regulators can ensure completely independent and transparent trading of NSE shares on its own platform.
