Depositories KPIs Explained: 4 Metrics That Drive Earnings
Team QuartrlyDepositories are the foundational infrastructure of Indian capital markets. CDSL and NSDL hold all dematerialized securities in India, earning fees from account maintenance, issuer charges, and transaction processing. Understanding depository KPIs is essential for evaluating these unique capital market infrastructure businesses.
Key Takeaways
- BO Accounts measure market penetration, but billable accounts matter more than total accounts for revenue
- Annual Issuer Charges provide stable, annuity-like income regardless of market conditions
- Transaction Charges are highly cyclical and depend on market volatility and delivery volumes
- Demat Custody Value reflects the total assets under safekeeping and influences fee potential
Understanding Depository Metrics
Depositories operate as regulated duopolies in India. NSDL (National Securities Depository Limited) and CDSL (Central Depository Services Limited) are the only two entities authorized to hold dematerialized securities. Their business model is fundamentally different from other financial services companies.
Unlike brokers who earn from trading activity, depositories earn from three sources: maintaining investor accounts, annual fees from listed companies (issuers), and charges on securities movement. This creates a mix of stable annuity income and cyclical transaction revenue. The regulatory nature of the business means fee structures are often subject to SEBI approval, limiting pricing power but providing competitive protection.
Beneficial Owner (BO) Accounts
What it is: A Beneficial Owner Account is a dematerialized account held by an individual or entity to store securities electronically. Each demat account opened with a Depository Participant (broker) creates one BO account at the depository level. This metric represents the total registered investor base.
Why it matters: BO account growth indicates market penetration and the expanding retail investor base in India. Higher account numbers create potential for transaction revenue and annual maintenance charges, though actual revenue depends on account activity and holdings.
What good looks like: Consistent incremental market share above 60-70% for new account additions signals competitive strength. CDSL crossed 13.5 crore registered demat accounts in Q2 FY25, demonstrating strong growth driven by partnerships with discount brokers.
Red flag: Rapid account growth without corresponding growth in Assets Under Custody or transaction revenue may indicate accumulation of dormant or low-value accounts. A high proportion of BSDA (Basic Services Demat Account) holders—accounts with portfolios under ₹2 lakh—generates minimal revenue despite database maintenance costs.
Example from earnings call:
"We became the first depository to surpass 13.5 crore registered demat accounts. In Q2 alone, 1.18 crore new demat accounts were opened." — CDSL Q2 FY25 Earnings Call
Annual Issuer Charges
What it is: Annual Issuer Charges are fees paid by listed companies to depositories for maintaining their securities in dematerialized form. Every company with shares held in demat format must pay this annual fee to the depository where those shares are registered.
Why it matters: This revenue stream is annuity-like in nature—once a company lists and its shares are dematerialized, it pays these charges every financial year regardless of market conditions. This provides stable, predictable income that remains constant through bull and bear markets.
What good looks like: Steady growth in issuer charges driven by new company listings and bonus issues. Double-digit annual growth in this segment indicates expanding market coverage. The metric is particularly valuable during market downturns when transaction income declines.
Red flag: SEBI regulates depository fees, and any increase in annual issuer charges requires regulatory approval. Management guidance indicating "no imminent change" in fee structure suggests limited near-term pricing power.
Example from earnings call:
"Any increase in annual issuer charges remains subject to SEBI approval; no imminent change announced." — CDSL Q2 FY25 Earnings Call
Transaction Charges
What it is: Transaction Charges are fees levied by depositories when securities are debited from a demat account. In practice, this means investors pay a small fee to the depository each time they sell shares. Buying shares (credits) typically does not incur depository transaction charges.
Why it matters: Transaction charges directly correlate with market activity and trading volumes. Higher delivery-based trading activity generates more transaction revenue. This is the most cyclical component of depository income.
What good looks like: High delivery volumes combined with market volatility drive transaction charge growth. Elevated F&O expiry weeks and market corrections that trigger selling activity can boost this revenue stream.
Red flag: Transaction income is inherently cyclical. A surge during bull markets should not be extrapolated as permanent growth. Prolonged buy-and-hold market phases or low delivery volumes will compress this revenue. Quarter-over-quarter volatility is normal for this metric.
Demat Custody Value
What it is: Demat Custody Value represents the total market value of all securities held in custody by the depository. It is calculated by multiplying the quantity of each security held by its current market price, aggregated across all BO accounts.
Why it matters: Custody value serves as a proxy for the depository's scale and the wealth represented by its investor base. Higher custody values can support arguments for premium fees and indicate the economic significance of the depository's role in the market infrastructure.
What good looks like: Rising custody values driven by both new account additions and market appreciation. A depository with custody value growth outpacing account growth suggests its users hold larger portfolios, which typically correlates with more active trading and higher fee generation.
Red flag: Custody value can decline sharply during market corrections without any operational deterioration. Analysts should evaluate custody value trends in conjunction with broader market indices to distinguish market-driven changes from competitive shifts.
Special Considerations
The BSDA (Basic Services Demat Account) Factor
SEBI mandates concessional charges for small investors through the BSDA framework. Accounts holding securities worth less than ₹2 lakh (threshold subject to change) qualify for reduced or waived annual maintenance charges. While this regulation expands market access, it creates a segment of accounts that cost money to maintain but generate minimal revenue.
When evaluating depository growth, investors should distinguish between total BO accounts and billable accounts. A depository reporting strong account growth primarily from small retail investors may face margin pressure as operational costs rise without proportionate revenue.
Regulatory Pricing Control
As critical market infrastructure, depositories operate under SEBI's oversight. Fee increases require regulatory approval, which limits the ability to raise prices even in inflationary environments. This regulatory framework provides competitive protection but caps revenue growth potential from existing services.
Quick Reference
| Metric | Definition | Healthy Range | Warning Sign |
|---|---|---|---|
| BO Accounts | Total registered demat accounts | >60% incremental market share | High growth with low custody value |
| Annual Issuer Charges | Yearly fees from listed companies | Double-digit YoY growth | Regulatory cap on fee increases |
| Transaction Charges | Fees on securities debits (sales) | Growth aligned with delivery volumes | Declining volumes in flat markets |
| Demat Custody Value | Total value of securities held | Growth exceeding market indices | Sharp decline during corrections |
