NSE's journey from challenger to market giant ends with a listing on BSE

The National Stock Exchange of India (NSE) completed one of the more unusual circles in India's financial history on Thursday, when its shares began trading on the Bombay Stock Exchange (BSE), the very institution whose dominance it was created to challenge.

The exchange's shares opened at ₹1,800 on the BSE against an issue price of ₹1,785, giving NSE a market capitalisation of more than ₹4.45 lakh crore at listing. The ₹22,562 crore initial public offering (IPO), which was entirely an offer for sale, had been subscribed 5.71 times.

The symbolism was striking. NSE was incorporated in 1992, recognised as a stock exchange by the Securities and Exchange Board of India (SEBI) in April 1993 and began operations in 1994. More than three decades later, the exchange built to break the old broker-controlled model of Indian trading had itself become a listed company on its historic rival.

NSE could not simply list its own shares on its own platform. Indian regulations prohibit an exchange from listing itself, creating the unusual situation in which the country's largest exchange had to choose another bourse for its public debut. NSE designated BSE as its listing exchange, while its shares were also admitted for trading under the permitted-to-trade category on Metropolitan Stock Exchange. NSE had earlier said it had not sought regulatory permission to trade its own shares on its platform.

But the significance of the listing goes well beyond the IPO. To understand why, it is necessary to go back to an Indian capital market that looked almost unrecognisable compared with today's electronic, nationwide system.

When a stock exchange was controlled by its brokers

In the late 1980s and early 1990s, the BSE was the dominant institution in Indian equity trading. It was owned and governed by its broker-members, and membership carried both trading and ownership rights.

A membership card was therefore more than a licence to trade. It was a scarce asset whose value was reinforced by restrictions on entry. Existing members had a direct interest in controlling who could participate in the exchange.

One of the stories from this period concerned Manohar J. Pherwani, then chairman of Unit Trust of India and already known in financial circles as the "Big Bull". According to an account that circulated in the market, Pherwani had sought a BSE membership for a UTI subsidiary in the late 1980s but was turned down.

The anecdote cannot be independently established, but versions of the story also suggested that ICICI and IDBI had sought entry and faced resistance. The alleged concern was that allowing major financial institutions into the exchange could take business away from brokers and encourage other institutions to demand membership.

Whether or not those individual accounts were accurate, they illustrated the institutional structure of the BSE at the time: access to the country's most important market was closely tied to its broker-members.

The pressure for change intensified after India's economic reforms began in 1991. Applications started reaching the Finance Ministry from groups seeking to establish stock exchanges in different parts of the country.

R.H. Patil, who would later become NSE's founding managing director, recalled that the ministry was overwhelmed by the number of applications. Pherwani was asked to suggest a way forward.

His answer was not another collection of regional exchanges but a national one.

Pherwani's idea gets a national blueprint

The committee was formally constituted by the Finance Ministry in January 1991. Its proposal envisaged a National Stock Exchange based in New Bombay and connected electronically to investors across the country.

The original concept was actually less confrontational than the exchange eventually became. NSE was initially expected to concentrate on medium-sized companies, bonds and debentures and complement the existing stock exchanges rather than directly displace them.

For the BSE, however, the implications were clear.

The exchange already accounted for about 70% of stock-market activity. A national, computerised market could weaken the geographical and institutional advantages on which its dominance rested.

Then came the securities scam of 1992.

The Harshad Mehta episode exposed the vulnerabilities of a financial system dependent on opaque transactions, weak settlement mechanisms and close relationships among banks, financial institutions and brokers. The ability of one of India's most prominent brokers to move enormous sums into the stock market strengthened the case for structural reform.

The same year produced another confrontation between brokers and the emerging regulatory regime.

When the newly established SEBI sought to bring brokers within its regulatory framework, BSE members resisted. The confrontation became sufficiently serious for trading at the exchange to be halted for a week in April 1992.

Finance Minister Manmohan Singh visited Bombay and met the protesting brokers.

For policymakers, the episode demonstrated the enormous influence that the country's dominant exchange and its broker community could exercise.

The government now had both a blueprint for a new exchange and a compelling regulatory argument for building one.

Patil's answer was to change the architecture

IDBI was asked to take the project forward. Its chairman S.S. Nadkarni assembled a small team that included Ravi Narain, Chitra Ramkrishna, Raghavan Puthran, Ashish Chauhan and K. Kumar. R.H. Patil, then an executive director at IDBI, joined the effort soon afterwards.

Patil was an unconventional choice for the job because he was not a stockbroker.

Born in Karnataka in 1937, he studied economics, earned a doctorate from the Bombay School of Economics and worked at the Reserve Bank of India before joining IDBI.

He later acknowledged that he knew relatively little about equity markets when he was given the assignment. Some of his well-wishers thought he was making a mistake. The task before him was to establish an institution capable of competing with some of the most powerful figures in Dalal Street.

Patil's response was to avoid competing with brokers on their own terms.

Instead, the new exchange would change the rules of the market.

Ownership, trading and management would be separated. Brokers would not control the board. Membership would not depend on buying a scarce and expensive BSE card. And trading would be electronic rather than conducted through an open-outcry ring.

Patil later characterised India's capital market of the early 1990s in extremely stark terms, comparing it with the Stone Age. Bad deliveries, fake share certificates and price manipulation were among the problems associated with the old system.

The objective was therefore not simply to create one more stock exchange. It was to redesign the way the market worked.

The technology that broke Mumbai's monopoly

The decisive innovation was the computer.

The BSE itself had considered moving towards screen-based trading. Mahendra Kampani, who served as its president, pushed computerisation, but jobbers and brokers feared that electronic trading would destroy the spreads and informational advantages on which many depended.

The proposal was eventually shelved.

NSE went in the opposite direction.

Its VSAT satellite network connected trading terminals across India to a central system. Orders could be entered electronically and matched through an anonymous order book.

That changed the geography of Indian trading.

A broker in Indore no longer had to send an order through a chain of intermediaries in Mumbai. A trader in Vijayawada could participate in the same market as one sitting in Dalal Street. Crucially, a participant did not have to know the identity of the person on the other side of the transaction.

NSE also attacked the economics of BSE membership.

Membership cards at the BSE could cost ₹30-40 lakh at the time. NSE instead offered pan-India membership against an interest-free deposit.

The exchange was consequently attacking two pillars of the old system simultaneously: Mumbai's geographical control and the scarcity value of broker membership.

NSE's own history records that it was among the first exchanges to establish widespread national reach through electronic trading and that screen-based trading commenced with its early operations.

The challenger overtakes the incumbent

There was no certainty that NSE would succeed.

The BSE had decades of history, deep liquidity and the country's most important listed companies. NSE, by contrast, was a government-backed experiment operating from a new building with an untested electronic system.

Established brokers dismissed it.

NSE began operations in the wholesale debt market in June 1994 and launched its equity market later that year. By October 1995, it had overtaken the BSE in equity trading.

By then, NSE was operating in 48 cities, 32 of which did not have their own stock exchanges, and was handling roughly two-and-a-half times the BSE's daily volumes.

Its early growth was not simply about putting computers on trading desks. It was about making access to the market independent of location, personal relationships and ownership of an exchange membership.

That distinction would become crucial.

The Reliance episode showed what had changed

One episode towards the end of 1995 illustrated how quickly the balance was shifting.

Reliance Industries accounted for roughly 15% of BSE turnover. The BSE then suspended trading in Reliance shares for three days over allegations involving duplicate share certificates.

Reliance responded by threatening to delist itself and some group companies from the BSE and move them to NSE.

The threat ultimately did not materialise. Intervention by BSE directors and the government led Reliance to back away.

But the episode demonstrated something that would have been difficult to imagine only a few years earlier: India's biggest companies could contemplate moving their market activity to a new exchange.

Ashish Chauhan, who was part of NSE's founding team, later recalled that within months transactions in Reliance group companies alone were running at about 80,000 a day on NSE.

The new exchange was no longer simply a government experiment.

Why the BSE struggled to regain lost ground

The BSE eventually embraced computerisation too. Its BOLT system went live in March 1995.

But NSE had already established screen-based trading as the new standard and had built a national network around it.

There was also an important institutional difference.

NSE had been created with a national mandate. The BSE's expansion beyond Mumbai was more constrained and required arrangements with regional exchanges. Exchanges in cities such as Calcutta and Delhi had little incentive to invite a stronger competitor into their markets.

By the time the BSE could expand more effectively, NSE had already established a national presence.

The BSE also faced dissatisfaction among smaller brokers who believed larger brokers received preferential treatment. NSE's model was built around more uniform treatment of its members.

In effect, NSE converted the BSE's traditional strengths into weaknesses.

The anonymous order book reduced the importance of personal networks. Deposit-based membership reduced the importance of scarce exchange cards. A professional management structure limited broker influence. And the satellite network reduced Mumbai's monopoly over information and access.

Competition reshaped the cost of trading

The consequences extended beyond the fortunes of the two exchanges.

Competition helped push brokerage charges down sharply. Rates that had been around 2% of transactions in the early 1990s began falling.

Screen-based trading also made the prices visible to customers more transparent and made some forms of manipulation more difficult.

The national network allowed investors outside Bombay to access a market that had previously depended heavily on intermediaries in the financial capital.

NSE continued to expand beyond its original equity and wholesale debt businesses. It established its clearing corporation in 1995, launched the Nifty 50 in the mid-1990s and expanded into derivatives after their introduction in India. Index options and single-stock futures and options were launched around 2000, while later years brought currency futures, securities lending and borrowing, ETFs and other products.

Its scale has since grown far beyond the market imagined by the Pherwani Committee. NSE says its unique investor base crossed 11 crore in January 2025 and that it processed more than 2,000 crore orders on a single day in July 2024.

Today, the exchange's importance is also reflected in its market share. Reuters reported ahead of the listing that NSE accounted for about 93% of cash-equity trading and 75% of options trading in India.

From disrupting the old exchange to joining the listed market

The final irony came with NSE's own public issue.

The exchange had spent more than three decades transforming the market from a broker-centred, Mumbai-based system into a nationwide electronic marketplace. Yet when NSE itself became a publicly traded company, it needed another exchange to host its shares.

The IPO offered 12.64 crore shares through an offer for sale and was priced at ₹1,785 a share after a price band of ₹1,700-1,785. The issue raised about ₹22,562 crore and attracted overall subscription of 5.71 times. Qualified institutional buyers subscribed 12.68 times, non-institutional investors 6.55 times and retail investors 1.39 times.

On September 24, NSE shares opened at ₹1,800 on BSE, around 0.84% above the issue price, and closed the first session at ₹1,818.

The exchange that had once been created to loosen the BSE's grip on Indian capital markets was therefore making its own public-market debut on the BSE.

Pherwani's original question was how India could create a genuinely national capital market. Patil's answer was to build an institution in which the broker was no longer the centre of the system.

The transformation that followed was ultimately larger than the rivalry between two exchanges. NSE changed how Indian investors entered the market, how orders were matched and how trading was distributed across the country.

Its listing on the BSE closes that historical loop in an unusually literal way: the institution created to challenge the old order has now become a listed company on the platform of the exchange whose old order it helped dismantle.
