What Is the Bombay Stock Exchange (BSE)?
The Bombay Stock Exchange (BSE) stands as India's oldest stock exchange and the first stock exchange established in Asia. Founded in 1875 by Premchand Roychand, BSE has been a cornerstone of India's financial markets for over 148 years. Located on the iconic Dalal Street in Mumbai, BSE has evolved from informal trading gatherings under a Banyan tree to one of the world's most sophisticated electronic trading platforms, listing over 6,000 companies and serving millions of investors across India and globally.
Historical Background and Evolution
The Bombay Stock Exchange has a rich and fascinating history that dates back to the 19th century. In the 1850s, a group of stockbrokers, led by businessman Premchand Roychand, began gathering under a Banyan tree on what is now Dalal Street in Mumbai. These informal meetings, known as the Native Share and Stockbrokers Association, marked the genesis of organized securities trading in India. The association was formally established as the Bombay Stock Exchange on July 9, 1875, making it the first stock exchange in Asia.

The Journey from Floor Trading to Digital
Initially, BSE operated on a floor trading system where licensed brokers would stand in trading rings and call out prices through open outcry. Investors outside the exchange would learn about stock prices only through newspapers the next day. This system had limitations in terms of transparency and efficiency. Recognizing the need for modernization, BSE partnered with CMC Ltd in 1995 to implement the BOLT (Bombay Online Trading) system, transitioning to fully automated electronic trading. This digital transformation revolutionized BSE's operations, enabling real-time price discovery, transparent order matching, and seamless access for investors nationwide.
