Why NSE's IPO Could Be a Bigger Deal for BSE Than Expected

NSE's long-awaited IPO is moving closer after the Supreme Court removed a major legal obstacle related to its past regulatory cases. But there's an unusual question at the centre of the IPO: Where will NSE's own shares trade? Under the current regulatory framework, NSE cannot formally list its shares on its own exchange. The concern is obvious: an exchange regulating a security while also operating the platform on which that security is listed creates a potential conflict of interest. That means NSE would need to list on another exchange, with

emerging as the natural venue. Recently, there was speculation that NSE shares could formally list on BSE but also trade on NSE under a separate “permitted to trade” arrangement. That possibility mattered for BSE investors. If NSE shares could trade on both platforms, BSE would face competition for the trading volumes generated by what could become one of India's biggest listed companies. But BSE's CEO has now said that NSE cannot self-list under the current regulatory framework, and BSE shares reacted positively to the clarification. The takeaway: This isn't just a story about NSE's IPO. It's also a story about market structure and competition. Where NSE shares eventually trade could determine who captures the trading volumes, liquidity and investor activity surrounding one of India's most anticipated listings.
