India’s Capital Market Infrastructure: A Deep Dive into Growth, Diversification, and Risk
India’s capital market infrastructure has evolved into a critical and rapidly expanding pillar of the nation’s financialization, representing a ₹ 70,000 crore market in FY25. The sector is underpinned by a powerful secular trend: the increasing financialization of household savings and a corresponding rise in equity allocation. This infrastructure is built upon four distinct segments that facilitate the country’s financial transactions and investments.
The market comprises the following segments:
This analysis dissects these four segments to address three critical questions of strategic trade-offs: Which can grow the fastest? Which has the most room to diversify? And which are best protected from regulatory changes?
1. Which Segments Are Poised for Faster Growth?
According to industry experts, exchanges and brokers are positioned for superior growth over the FY26-28 period, primarily by capitalising on the structural shift towards higher-volume derivatives trading. This outperformance is fueled by the explosive popularity of specific product classes, most notably weekly index options like the SENSEX weekly options, which have reshaped market dynamics and revenue streams.
2. Who Has the Greatest Scope to Diversify?
Analysis shows that RTAs and brokers are best-positioned to diversify their revenue streams by expanding into new lines of business, leveraging their unique core competencies.
Brokers and RTAs: Leading the Way
* Brokers are using the massive operating cash flows generated from their primary business as an engine to fund strategic expansion. They are actively diversifying into new product areas such as margin trading facilities (MTF), commodities, and wealth management services.
* RTAs are leveraging their core, defensible expertise in complex data management and registry services to expand into adjacent financial sectors and international markets, including Alternative Investment Funds (AIF) and Portfolio Management Services (PMS).
Exchanges and Depositories: A More Focused Path
* Exchanges, while capable of introducing new products, face a more protracted path to diversification. Building the necessary liquidity to make new offerings viable is a time-intensive process that can moderate the pace of revenue stream expansion.
* Depositories face structural limitations to diversification. While they have added ancillary services, their opportunities outside the core business are constrained, partly due to an already high market share in related services like the KYC Registration Agency (KRA).
3. Which Segments Offer the Strongest Regulatory Protection?
RTAs are at a lower risk from regulatory changes compared to the other capital market infrastructure segments. The primary reason for this insulation is their nil exposure to options trading, which is the key area of current regulatory focus and intervention.
The link between high growth and high risk is explicit for other segments. The outsized growth of exchanges and brokers is precisely because of their exposure to weekly options, which account for an estimated 70-80% of their revenues. This concentration makes regulatory scrutiny an inherent consequence of their success.
* Brokers and Exchanges: These segments have high exposure to potential regulations targeting weekly index options.
* Exchanges: This segment faces the additional risk of a potential regulator-driven divestment of their clearing corporations. Because owning these corporations constitutes a “major cost/service advantage,” such a move would threaten their fundamental business moat and could impact earnings.
* Depositories: This segment faces persistent pricing risks, as any changes to their fee structures must be approved by the regulator (SEBI).
On a positive note, potential regulatory efforts aimed at deepening the cash markets could serve as a beneficial catalyst for both depositories and brokers.
Conclusion: A Segmented Outlook
The Indian capital market infrastructure presents a clear dichotomy: investors seeking high growth must accept significant regulatory exposure concentrated in derivatives, while those prioritising stability will find it in the lower-growth, but well-protected, ancillary services. Each segment offers a distinct profile of risk and reward.
- Fastest Growth: Brokers and Exchanges
- Highest Diversification Scope: RTAs and Brokers
- Strongest Regulatory Protection: RTAs
