Clearing Corporations: NSE Clearing, ICCL Guide
Understanding clearing corporations in India - NSE Clearing and ICCL roles, functions, risk management, settlement guarantee, and how they ensure market integrity.
Introduction: The Invisible Guardians of Market Integrity
“In every trade you execute, there’s an invisible entity that guarantees you’ll receive your shares or money—the clearing corporation.”
Clearing corporations are the unsung heroes of financial markets. They stand between buyers and sellers, guaranteeing settlement even if one party defaults. Without them, market confidence would collapse. Understanding clearing is essential for grasping how modern markets function.
What is a Clearing Corporation?
Definition
A clearing corporation (also called clearing house) is an entity that:
- Interposes between buyers and sellers
- Becomes buyer to every seller
- Becomes seller to every buyer
- Guarantees settlement
Central Counterparty (CCP) Model
How It Works:
- Trade Execution: Buyer buys from Seller on exchange
- Novation: Clearing corp steps in between
- Two Contracts:
- Buyer owes clearing corp
- Clearing corp owes seller
- Settlement Guarantee: Even if one party defaults
Visual Flow:
Without CCP: Buyer ←→ Seller (direct counterparty risk)
With CCP: Buyer → CCP ← Seller (CCP guarantees both)

Risk Management Framework
Margin Types

| Price Move | Volatility Move | Outcome |
|---|---|---|
| +3 range | Unchanged | Loss scenario 1 |
| -3 range | Unchanged | Loss scenario 2 |

Netting and Novation
Multilateral Netting
Definition: Offsetting all buys and sells to arrive at net obligation
Example:
| Trade | Quantity |
|---|---|
| Buy from A | 100 shares |
| Sell to B | 50 shares |
| Buy from C | 30 shares |
| Sell to D | 60 shares |
| Net Obligation | Buy 20 shares |
Benefits:
- Reduces settlement volume
- Lower capital requirement
- Fewer transactions
Novation
Process:
- Trade happens between A and B
- Clearing corp interposes
- Original contract replaced by two contracts:
- A with CCP
- B with CCP
- No direct link between A and B
Legal Effect: Parties’ obligation is to/from CCP only
Settlement Process
T+1 Settlement (Current)

Frequently Asked Questions
Q: If my broker defaults, will I get my money? A: The clearing corporation guarantees settled trades. However, money/securities lying with broker (not yet traded) may be at risk. This is why segregation of client funds is important.
Q: Why do I need to pay margin for delivery trades? A: Until settlement happens (T+1), there’s risk. Margin ensures you can pay. Post-settlement, no margin needed for delivery holdings.
Q: What happens if clearing corporation itself fails? A: Extremely unlikely given multiple safeguards (SGF, stress testing, SEBI oversight). It would be a systemic event requiring regulatory intervention.
Q: Do I interact with clearing corporation directly? A: No. Your broker/clearing member interfaces with CC. As retail investor, you deal with broker who handles clearing.
Q: Why is T+1 settlement beneficial? A: Faster access to funds, lower counterparty risk, reduced margin requirements. India is among leaders globally in settlement speed.
Clearing corporations are the invisible infrastructure that enables trust in financial markets. Every time you buy or sell a stock with confidence that you’ll receive what you’re owed, thank the clearing corporation standing behind that promise.
