Bombay Stock Exchange (BSE)

Brokers once traded under a banyan tree, on a street now called Dalal Street. That tree grew into Asia’s oldest stock exchange.

BSE

Bombay Stock Exchange. Asia’s oldest stock exchange, founded in 1875.

Sensex

BSE’s benchmark index. It tracks 30 large, established companies.

Demutualised

An exchange whose ownership is kept separate from its trading members.

From a Banyan Tree to Hosting NSE’s Own IPO

A single informal gathering under a tree grew into Asia’s oldest exchange. Now that same exchange stands to gain from its younger rival’s IPO.

What Are the Key Milestones?

• 9 Jul 1875: Premchand Roychand and fellow brokers formally found the Native Share and Stock Brokers’ Association.
• 1957: BSE becomes the first Indian exchange recognised under the Securities Contracts (Regulation) Act.
• 1 Jan 1986: The Sensex begins publication.
• 14 Mar 1995: BOLT, BSE’s own electronic trading system, is commissioned.
• 19 May 2007: BSE is demutualised and corporatised.
• 30 Dec 2016: BSE launches India INX at GIFT City, Gujarat.
• 3 Feb 2017: BSE Limited itself lists on rival exchange NSE, under the ticker “BSE.”
• Sep 2026: BSE stands to gain trading fees, as NSE’s own shares prepare to list on BSE.

Asia’s Oldest Exchange

• BSE is Asia’s oldest stock exchange, and ranks among the ten oldest in the world.
• It grew out of informal broker gatherings under a banyan tree, from the 1850s. This happened on what is now Mumbai’s Dalal Street.

Formal Founding and the Sensex

• Premchand Roychand and fellow brokers formally established BSE on 9 July 1875, as the Native Share and Stock Brokers’ Association.
• BSE was the first Indian exchange recognised by the government, under the Securities Contracts (Regulation) Act, 1956.
• Its benchmark index, the Sensex, has been published since 1 January 1986. It tracks 30 large, established companies.
• BSE was demutualised and corporatised on 19 May 2007, decades after its founding. This separated ownership from trading membership.
• BSE Limited itself later listed on rival exchange NSE, on 3 February 2017, under the ticker “BSE.”

Moving to Electronic Trading

BSE moved to electronic trading through BOLT, commissioned on 14 March 1995. This came about five months after NSE’s own launch.

India INX and BSE’s Wider Reach

• In 2016, BSE launched India INX at GIFT City, Gujarat. This was India’s first international stock exchange.
• In 2018, BSE became the first Indian exchange to launch commodity derivatives contracts, in gold and silver.
• BSE lists over 5,600 companies, with a market capitalisation of roughly $5 trillion. Yet it handles a smaller share of India’s actual day-to-day trading volume than NSE.
• The Sensex’s base year is 1978-79, with a base value of 100.
• BSE’s headquarters, the Phiroze Jeejeebhoy Towers, still stands on Dalal Street. That is the same street its founding brokers first gathered on.
• In FY 2025-26, BSE’s SME platform saw 146 listings. This was up 87% from 78 the year before.

Premchand Roychand’s Fortunes

Premchand Roychand made separate fortunes in cotton and bullion trading. He was known in his own time as the “Cotton King” and the “Bullion King.”

NSE, the Younger Rival

• See National Stock Exchange (NSE), BSE’s younger, faster-growing rival, founded 117 years later.
• See SEBI, the regulator that oversees both BSE and NSE.
• Where NSE was designed electronic and demutualised from its 1992 founding, BSE carried a century-old broker-owned structure. BSE only demutualised in 2007, and moved to screen-based trading in 1995.
• BSE’s Dalal Street address has become shorthand for the Indian stock market itself, much like “Wall Street” in the United States.

Exam Point of View

The Date and Structure Traps Examiners Set

• No UPSC question has directly tested BSE’s founding history, so far.
• Sequence trap: keep three dates separate — 1875 founding, 1957 government recognition, and 2007 demutualisation.
• Electronic trap: despite being much older, BSE moved to electronic trading in 1995, only after NSE’s launch, not before it.
• Listing trap: BSE Limited itself is listed on NSE, not on itself. No exchange can list its own shares on itself.

Current Affairs

BSE Stands to Gain From NSE’s IPO

• Since NSE cannot list its own shares on itself, every NSE share traded after its IPO will trade on BSE’s platform instead.
• Higher trading volumes on BSE generally mean higher transaction-fee revenue, for BSE.
• BSE’s own share price has risen sharply, up nearly 49% over the past year, partly on this expectation.

A Persistent Market-Share Gap

BSE’s cash-market trading share has stayed in the 6-8% range for several years, despite listing far more companies than NSE. The NSE IPO could draw more investors to BSE’s cash market, helping narrow that gap. Analysts caution that some of this expected benefit may already be priced into BSE’s stock.
