Financial Intermediaries
Brokers, depositories, DPs, clearing corps, banks. Who does what behind every trade and why all of them are needed.
The supply chain behind a single trade
When you tap Buy on a brokerage app, what looks like a single act actually moves through five regulated entities, each with a narrow role. Understanding who does what makes you a better investor — you’ll know who to call when something goes wrong, what each fee on your contract note pays for, and where the real risks sit.
The stock broker
The broker is your interface to the exchange. They route your order to NSE or BSE, collect brokerage, generate contract notes, and provide the trading terminal — whether that’s a mobile app like Zerodha Kite or a desktop platform like the older NEAT or NOW.
Brokers come in three flavours:
- Discount brokers — Zerodha, Groww, Upstox, Dhan, Angel One. Flat ₹20 per executed equity intraday order; ₹0 for delivery equity. No advice, just execution. Best for self-directed retail investors.
- Full-service brokers — ICICI Direct, HDFC Securities, Kotak Securities, Motilal Oswal. Percentage-based brokerage (0.3-0.5%) but bundled with research, advisory, and relationship managers.
- Institutional brokers — for mutual funds, FIIs, family offices. Different pricing, different infrastructure (DMA, co-location).
SEBI requires brokers to keep client funds segregated from their own, maintain a minimum net worth, and follow strict margin and reporting rules. Failures here are how broker frauds happen.
Depositories and DPs
India has exactly two depositories: NSDL (National Securities Depository Limited) and CDSL (Central Depository Services Limited). Both hold shares in electronic form on behalf of investors. Depositories don’t deal with retail clients directly — they appoint Depository Participants (DPs) as intermediaries. When you open a demat account, you’re actually opening it with a DP, who in turn is connected to one of the two depositories.
Your broker is usually also a DP. Zerodha is a DP with CDSL; HDFC Securities is a DP with NSDL. Some investors deliberately split — trading account with a discount broker, demat account with a bank’s DP — for safety.
What the depository actually does: maintain ownership records, process corporate actions (dividends, bonuses, splits), enable pledge of shares as collateral, and settle the share leg of trades.
Clearing corporations
When you buy 10 shares of Reliance from someone you’ve never met, who guarantees that you’ll get the shares and they’ll get the money? The clearing corporation. NSCCL (NSE Clearing) and ICCL (Indian Clearing Corp., for BSE) sit between every buyer and seller as the central counterparty. Even if the original counterparty defaults, the clearing corp honours the trade — it has skin in the game via margins collected from brokers.
This is why exchanges insist on margins. Without margin, the clearing corp has no buffer if a broker fails. With T+1 settlement (rolled out gradually 2021-2023), the clearing window has shrunk and the system as a whole carries less risk.
Banks
The bank is where your money lives before and after a trade. You link a bank account to your broker via mandates (UPI, electronic mandate, or net banking). For every trade, funds move bank → broker pool account → clearing corp → counterparty’s broker → counterparty’s bank. SEBI rules cap how long brokers can hold client funds in their own account before sweeping to the clearing corp.
Some banks — HDFC, ICICI, SBI, Kotak — also operate as brokers, DPs, and AMCs simultaneously, which simplifies onboarding but concentrates a lot of moving parts under one roof.
Other intermediaries you’ll meet
- Registrars & Transfer Agents (RTAs) — Link Intime, KFin Tech. Maintain shareholder registers, process IPO allotments, handle dividend payouts.
- Custodians — for FIIs and mutual funds. Hold securities, oversee compliance.
- AMCs — manage mutual funds. SBI MF, HDFC MF, ICICI Pru MF are the largest by AUM.
- KYC Registration Agencies (KRAs) — Karvy, NDML, CDSL Ventures. One-time KYC verification shared across the industry.
Each charges a small fee. Add them up and the all-in cost of a retail equity trade is still well under 0.5%, which is one reason equity participation has democratised.

The Five Intermediaries That Touch Every Trade You Place
When you tap “Buy” on Zerodha Kite or Groww, your single order travels through at least five distinct entities before settlement. Knowing them helps you diagnose problems — a stuck order may be your broker’s risk system, the exchange matching engine, or the depository confirmation step.
| Intermediary | Function | Regulator |
|---|---|---|
| Broker (Zerodha, Groww, Upstox, ICICI) | Order routing, risk-margin checks, account opening | SEBI Stock Broker Regulations |
| Exchange (NSE, BSE) | Order matching, price discovery, market data dissemination | SEBI |
| Clearing Corporation (NSE Clearing, ICCL) | Trade novation — becomes counterparty to both sides | SEBI |
| Depository (NSDL, CDSL) | Holds shares in dematerialised form | SEBI Depositories Act |
| Depository Participant (your broker, mostly) | Account-holder interface to the depository | SEBI |
Why Clearing Corporations Are the Hidden Lynchpin
Indian markets operate as central counterparty (CCP) systems. When you buy 100 shares of HDFC Bank, the clearing corporation instantly steps between you and the seller — you owe NSE Clearing money, NSE Clearing owes you shares. This novation is what makes Indian markets functionally risk-free at the retail level. The clearing corp maintains a Settlement Guarantee Fund (SGF) of ₹15,000+ crore at NSE Clearing alone, plus member margin deposits, to absorb any default. The 2008 Lehman crisis or local broker defaults (BMA Wealth, Anugrah Stock Broking) did not affect retail clients because of this CCP architecture — a major Indian market strength.
FAQs — Intermediary Choice
Discount broker vs full-service broker — which is better?
Discount brokers (Zerodha, Groww, Upstox) charge zero brokerage on delivery and ₹20/order on intraday/F&O. Full-service brokers (ICICI Direct, HDFC Securities) charge 0.3-0.5% per trade but bundle research and relationship support. For self-directed investors with research routines, discount wins on cost. For first-timers wanting hand-holding, the higher cost can be justified.
NSDL vs CDSL — does my choice matter?
Functionally identical. Most discount brokers default to CDSL (faster, slightly cheaper); ICICI Direct and HDFC Securities default to NSDL. Either depository holds your shares safely.
What is a Power of Attorney (POA) and should I sign it?
POA authorises the broker to debit shares from your demat account when you sell. SEBI replaced POA with the digital “DDPI” (Demat Debit and Pledge Instruction) in 2022. Sign it — without it, every sale requires a separate authorisation OTP, which slows trading.
The 2020 Karvy Stock Broking Episode — A Cautionary Tale
Karvy Stock Broking, once among India’s top brokerages with 12 lakh clients, collapsed in November 2019 when SEBI discovered they had illegally pledged client securities worth ₹2,300 crore to raise funds for themselves. The case revealed two lessons every retail investor must internalise: (1) Power of Attorney was being misused for unauthorised pledging — fixed by SEBI’s 2022 transition to digital DDPI authorisation; (2) Brokers earning on client float (idle cash) had perverse incentives — addressed by upstreaming all client funds to clearing corporations within T+1. The CCP architecture protected client claims; eventually 95%+ of Karvy clients were made whole through the SEBI-administered process. Lessons for today: verify your demat balance regularly via NSDL/CDSL portals; never sign physical POA when DDPI is available; and prefer brokers with transparent zero-float models like Zerodha and Groww.
