Executive Summary
India's capital markets infrastructure is benefiting from a structural transition as household savings shift from physical assets like gold and real estate toward financialized instruments. At the core of this architecture sit Market Infrastructure Institutions (MIIs) such as depositories (CDSL, NSDL) and exchanges (NSE, BSE, MCX), alongside Registrar and Transfer Agents (CAMS, KFintech) and retail brokerages. These entities function as tollbooths on the financial system, enjoying immense pricing power, regulatory entry barriers, and exceptional operating leverage.
The financial profiles across this value chain are among the strongest in corporate India. Depositories and exchange platforms operate at EBITDA margins often exceeding ~55% to ~65%, requiring negligible incremental capex to process explosive volume growth. Once fixed technology infrastructure costs are covered, every additional trade execution, demat account opening, or corporate action incurs virtually zero marginal cost, translating directly into cash conversion rates above ~85%.
However, the ecosystem is not without cyclical sensitivity. Top-line revenues for discount brokerages and transaction fee-dependent exchanges remain tied to cash market equity turnover and derivative trading intensity. Regulatory interventions by SEBI, particularly around F&O lot sizes, true-to-label fee structures, and margin rules, introduce periodic regulatory friction. Investors must distinguish between cyclical trading volume spikes and secular asset-gathering moats like demat holding charges, mutual fund RTA fees, and listing revenues.
For institutional allocators and family offices, market infrastructure represents a high-return, capital-light proxy on India's broader macroeconomic tailwinds. Unlisted assets like NSDL and NSE offer unique pre-IPO scarcity value, while listed incumbents like CDSL, BSE, and CAMS provide liquid exposure to the structural deepening of domestic equity participation.
Overview
The Indian capital market infrastructure ecosystem is structured as an oligopoly by design, heavily regulated by SEBI to preserve systemic integrity. At its base are the two primary depositories, CDSL and NSDL, which maintain the electronic registry of securities held by investors. This duopoly is complemented by dominant trading venues, primarily NSE in equity derivatives and cash trading, and BSE, which has engineered a dramatic turnaround in index options while maintaining a near-monopoly in debt and equity primary listings.
Upstream demand is anchored by a rapid expansion in retail equity participation. Total active demat accounts in India have surged past ~160 million in FY25E, up from roughly ~40 million in FY20. This trajectory is reinforced by systematic investment plan (SIP) inflows into mutual funds, which consistently average over ~$2.5 Bn per month. Supporting this asset pipeline are specialized Registrar and Transfer Agents like CAMS and KFintech, which manage investor servicing, transfer processing, and compliance for roughly ~90% of the domestic mutual fund industry.
On the distribution front, discount broking platforms like Zerodha, Angel One, and Groww have replaced traditional full-service brokerages as primary market gateways. These platforms rely on high technology uptime and low customer acquisition costs to capture retail order flow, generating revenues through transaction charges, margin trading facility (MTF) interest, and distribution commissions.
Supply-side dynamics are characterized by massive technological entry barriers and regulatory moats. Obtaining an MII license from SEBI requires stringent capital adequacy, robust cybersecurity audits, and proven disaster recovery systems. Consequently, incumbent exchanges and depositories face virtually zero risk of new domestic entry, allowing them to extract persistent economic rents as trade velocity increases.

Key Highlights
Growth Drivers
- Demographic Dividend & Equity Penetration: Low baseline equity participation (~7–9% of Indian households vs >55% in the US) provides a decades-long runway for demat additions.
- SIP Micro-Inflows: Monthly mutual fund SIP contributions exceeding ~$2.5 Bn create institutionalized buying pressure, lifting RTA AAUM asset bases organically.
- Corporate Actions & IPO Boom: Record levels of mainboard and SME initial public offerings generate elevated issuer fee income for depositories and primary exchange venues.
- Technology Accessibility: Frictionless digital onboarding via Aadhaar-based e-KYC and UPI has lowered customer acquisition costs for digital brokerages by over ~60% relative to legacy models.
- Shift to Unlisted Dematerialization: Regulatory mandates requiring unlisted public and private companies above specific size thresholds to dematerialize shares create a step-function growth in depository issuer base.

Unit Economics
- Depositories earn ~₹3.5 to ~₹5.5 per transaction fee on debit of securities from demat accounts, supplemented by annual issuer charges from listed and unlisted companies (~₹9,000 to ~₹25,000 per issuer depending on capital size).
- Mutual Fund RTAs charge asset management companies (AMCs) an basis-point tiered fee structure linked to total Average Assets Under Management (AAUM), where equity AAUM yields higher realizations (~3.5 to ~5 bps) than debt (~1 to ~1.5 bps).
- Exchanges monetise execution through volume-tiered transaction charges (e.g., ~₹2,500 to ~₹3,200 per crore of premium turnover in options), co-location server rack rentals, and real-time market data feed licensing.
- Discount brokerages generate ~₹20 per executed flat-fee order on equity intraday and F&O, while capturing ~12–16% annualized net interest margins on Margin Trading Facility (MTF) book balances funded via low-cost balance sheet cash.
Value Chain & Profit Pools
- Primary Issuer / Asset Creator: Companies issuing equity/debt and AMCs launching fund schemes.
- Registrars & Transfer Agents (RTAs): CAMS and KFintech handle record-keeping, unit creation, and investor servicing for AMCs.
- Trading Venues (Exchanges): NSE, BSE, and MCX provide order-matching engine infrastructure and price discovery.
- Market Intermediaries (Brokers): Discount platforms (Groww, Zerodha, Angel One) and institutional desks route client order flows.
- Depositories & Custodians: CDSL and NSDL hold electronic assets; custodians (e.g., Orbis, ICICI Bank) manage institutional asset safety.
- Clearing & Settlement: Clearing corporations (NSCCL, ICCL) guarantee trade settlements, absorb counterparty risk, and earn interest on float money.

Valuation & Comparables
- Market infrastructure institutions trade at structural valuation premiums (~30x to ~55x forward P/E) driven by quasi-monopolistic positioning, clean cash generation, and near-zero capital intensity.
- RTA valuation multiples correlate directly with the proportion of equity AAUM in their asset mix; higher equity share yields structurally higher profit margins and commands premium earnings multiples.
- Retail brokerages face cyclic multiple compression (~12x to ~22x forward P/E) during periods of SEBI regulatory tightening or retail volume pullbacks, reflecting higher earnings volatility relative to MIIs.
- Re-rating triggers include index inclusion, fee structure hikes approved by regulators, acceleration in corporate action revenue, and successful monetization of non-transactional data feeds.
Scenarios
Bull case
Retail equity participation hits ~15% of households by FY30E; monthly SIP flows cross ~$4.5 Bn, and derivative turnover stays resilient post-regulatory adjustments.
Implication: Sector revenue expands at ~21% CAGR; depository and exchange multiples expand toward upper historical ranges (~50x+ P/E) on operating leverage.
Base case
Demat accounts grow at ~14–16% annually; SIP flows stabilize around ~$3.0–$3.5 Bn; SEBI's regulatory measures moderately temper options churn but preserve ecosystem health.
Implication: Sector compounding matches expected ~16.5% CAGR; strong dividend payout yields (~40-60% of earnings) provide downside protection.
Bear case
Severe prolonged equity market correction reduces retail activity by ~30%; stringent SEBI curbs on retail options trading severely compress derivative exchange fees and broker margins.
Implication: Brokerage earnings fall ~25–35%; exchange and depository earnings growth slows to ~6–8% CAGR with ~20% multiple de-rating.
Policy & Regulatory Landscape
- SEBI True-to-Label Fee Mandate: Directs exchanges and depositories to pass volume rebates directly to end-investors rather than retaining tiered margin spreads, impacting broker-exchange economics.
- Options Contract Expiry & Lot Size Restructuring: SEBI measures restricting weekly contract expiries and increasing contract values to curb retail derivative over-speculation, impacting trading turnover.
- Mandatory Dematerialization for Unlisted Entities: Regulatory mandate requiring private companies to dematerialize securities expands depository addressable issuer base.
- Cybersecurity & Operational Resilience Frameworks: Increased regulatory scrutiny demanding enhanced redundant infrastructure, disaster recovery drills, and strict data sovereignty standards.
The Investor's Edge - what most research misses
- Consensus overemphasizes monthly demat additions while underestimating the stickiness of annual issuer maintenance fees collected by depositories from corporate balance sheets.
- Regulatory tightening on derivative trading is often mispriced as a terminal growth threat; historically, structural market infrastructure handles regulatory shifts by recalibrating underlying volume structures without long-term margin destruction.
- Pre-IPO valuation arbitrage between unlisted entities like NSE/NSDL and listed peers like BSE/CDSL often obscures differing revenue mixes, with NSDL carrying higher institutional custodian share and NSE holding a derivative volume stronghold.
- Float income on clearing house margins and broker cash balances creates a counter-cyclical revenue hedge during elevated interest rate environments.
Investment Outlook
The capital markets infrastructure sector in India is positioned to compound revenue at ~16.5% CAGR over FY26–30E, driven by systematic financialization of household savings. Short-term volatility from regulatory updates around equity derivatives will likely be absorbed by secular gains in demat account adoption and rising mutual fund SIP bases. Market infrastructure entities with tollbooth business models will continue to deliver industry-leading operating margins and capital efficiency.
Catalysts to Watch
How Investors Can Play It
- Unlisted Exposure: Pre-IPO institutional blocks in NSE and NSDL offer rare opportunities to acquire high-moat infrastructure before public listing liquidity events.
- Listed Infrastructure Proxies: CDSL and BSE provide direct liquid exposure to market turnover and depository expansion, trading at valuations reflective of their asset-light tollbooth characteristics.
- Asset-Servicing Play: CAMS and KFintech allow investors to play the equity mutual fund tailwind without taking direct asset manager performance or equity market timing risk.
- Key Entry Metric: Monitor monthly active demat account additions, cash-to-derivative turnover ratios, and retail trading participation rates as leading indicators for quarterly revenue momentum.
Key Risks
- Regulatory Fee Interventions: SEBI capping transaction charges, demat debit fees, or RTA asset-servicing basis points could compress operating margins.
- Retail Participation Churn: A prolonged bear market in mid and small-cap equities could cause sharp drops in active trading clients and lower demat account additions.
- Technology Failure & Cyber Threats: Centralized platform outages or data security breaches present tail-risk operational and regulatory penalties.
- Unlisted Share Liquidity Bottlenecks: Pre-IPO shares of key market entities (e.g., NSE, NSDL) face regulatory overhangs, delay risks in listing approvals, and transfer constraints.
The Neoma View
Neoma views capital market infrastructure as one of India's most compelling high-return, capital-light structural bets. While retail brokerage earnings remain inherently cyclical and exposed to SEBI regulatory adjustments, core depositories and market infrastructure exchanges possess irreplaceable competitive moats. We favour exposure to sticky asset-gathering platforms and pre-IPO infrastructure assets that compound capital independent of short-term market fluctuations.
