Overview

The Inter-connected Stock Exchange of India (ICSE), established in 1998 and headquartered in Mumbai, is a multi-exchange trading network designed to enhance market liquidity by connecting regional stock exchanges.

History

The Inter-Connected Stock Exchange of India emerged from concerns about the fragmented structure of India's securities markets. In October 1996, the Federation of Indian Stock Exchanges discussed the creation of an Inter-Connected Market System and established a steering committee to develop the concept. The proposed exchange was intended to allow members of participating regional exchanges to access a shared national platform rather than relying exclusively on geographically limited local markets. ISE was subsequently promoted by a group of regional stock exchanges and incorporated in 1998 under the regulatory framework of SEBI and the Securities Contracts (Regulation) Act, 1956. It began operations in the Mumbai area and commenced trading on 26 February 1999. The participating institutions included regional exchanges associated with cities such as Bengaluru, Bhubaneswar, Chennai, Kochi, Coimbatore, Guwahati, Indore, Jaipur, Kanpur, Mangalore, Patna and Vadodara. The initiative was described as an exchange of stock exchanges because the members of the participating regional exchanges were expected to become the trading community on the interconnected platform. The operating model combined trading access with post-trade and market-support functions. ISE provided facilities for capital-markets trading, clearing, settlement, risk management and surveillance. It also offered membership to qualifying individuals, partnership firms and corporate entities. Members were able to execute transactions for themselves and their clients. The exchange aimed to provide a liquid national market for securities already traded on Indian exchanges and to create a route through which companies could obtain equity-market visibility and capital. ISE expanded into related services. Its depository-participant operations supported dematerialisation, rematerialisation, pledging of dematerialised securities, electronic access to securities information and settlement through depository systems. The organisation was associated with CDSL and NSDL services and established branches and collection centres in multiple Indian cities. In November 2000, it created a training centre offering classroom programmes in equity trading and settlement, derivatives, day trading, arbitrage, technical analysis, financial planning and regulatory compliance. These activities reflected an effort to build a broader market-services institution rather than a trading venue alone. The exchange did not achieve the scale envisaged by its promoters. Initial turnover was reported at roughly Rs. 1–2 crore per day during the first six months, but activity later fell close to zero. The platform faced weak participation from major brokers connected with the regional exchanges, which had limited commercial incentives to redirect trading to ISE. The regional exchanges also continued to operate their own segments, so the underlying market remained divided. Competition from the National Stock Exchange and Bombay Stock Exchange further reduced the prospects of a new venue achieving meaningful liquidity. ISE also struggled to obtain a significant base of listed companies, including because the regulatory arrangements for extending its regional listing area did not produce the intended result. On 8 December 2014, SEBI permitted ISE to exit the stock-exchange business. That decision effectively ended the exchange's role as an operating national securities market. Its history illustrates both the difficulty of consolidating regional financial markets and the competitive advantages enjoyed by larger Indian exchanges with deeper liquidity, broader participation and stronger network effects.

Brand decisions

  • 2014

    Exit from the stock-exchange businessStrategy

    Background

    ISE failed to establish sustained liquidity against larger Indian exchanges, while its participating regional exchanges continued to operate fragmented local markets. Trading activity and the platform's ability to attract listings weakened substantially.

    Action taken

    SEBI permitted the exchange to withdraw from the stock-exchange business on 8 December 2014.

    Aftermath

    The decision ended ISE's role as an operating national securities exchange and left the interconnected-market initiative as a historical example of an unsuccessful regional-market consolidation effort.
