Chapter 8: Clearing and Settlement — Complete Study Notes (Part 1 of 3)

8.0 Overview of Clearing and Settlement in the F&O Segment

The clearing and settlement of all derivative trades executed on the Futures & Options (F&O) segment of the National Stock Exchange of India Limited (NSE) are undertaken by the National Securities Clearing Corporation Limited (NSCCL).

NSCCL plays a pivotal role in maintaining market integrity by acting as the legal counterparty to every trade executed on the F&O segment, thereby guaranteeing financial settlement through the legal mechanism of novation.

The entire clearing and settlement framework established by NSCCL rests upon three fundamental pillars:

1. Clearing: Working out open positions and net obligations of clearing participants.
2. Settlement: Executing daily and final mark-to-market and exercise cash flow adjustments.
3. Risk Management: Enforcing real-time position monitoring, capital adequacy rules, and stringent margin collection mechanisms.

8.1 Clearing Entities

Clearing and settlement activities in the F&O segment are executed by NSCCL with the operational support of specialized clearing entities and financial intermediaries.

8.1.1 Clearing Members (CMs)

Clearing Members are primary participants responsible for settling trades with NSCCL and managing collateral/margins. In the F&O segment, Clearing Members are classified into three distinct categories:

1. Self-Clearing Members (SCM):

   • Members who clear and settle trades executed by them exclusively, either on their own proprietary account or on behalf of their own clients.
   • SCMs cannot clear trades executed by other Trading Members.

2. Trading Member-cum-Clearing Members (TM-CM):

   • Trading Members who clear and settle their own proprietary and client trades, and additionally clear and settle trades for other Trading Members (TMs) who choose to clear through them.

3. Professional Clearing Members (PCM):

   • A special category of Clearing Members who are not Trading Members of the exchange.
   • PCMs are typically financial institutions, custodians, or banks that clear and settle trades executed by multiple Trading Members.

Additional Security Deposit Requirement

Clearing Members clearing trades for other Trading Members (TM-CMs and PCMs) are required to deposit additional security deposits with NSCCL in respect of every Trading Member whose trades they undertake to clear and settle.

8.1.2 Clearing Banks

Funds settlement in the F&O segment is routed through NSCCL-designated Clearing Banks.

• Account Opening Requirement: Every Clearing Member is required to open a separate, designated F&O bank account with an NSCCL-approved Clearing Bank.
• Function: All monetary obligations—including daily mark-to-market (MTM) losses/profits, option premium payments, exercise settlement funds, and margin pay-ins/pay-outs—are automatically debited or credited through these designated accounts on instructions from NSCCL.

8.2 Clearing Mechanism

The primary objective of the clearing mechanism is to systematically compute the open positions and net financial obligations of Clearing Members at the end of each trading day. These calculated open positions form the basis for exposure monitoring, intraday risk surveillance, and daily margin requirements.

8.2.1 Hierarchical Aggregation of Open Positions

Open positions are determined through a structured hierarchy from the client/proprietary level up to the Clearing Member level:

1. Order Identification at Order Entry:

   • When entering orders on the NEAT-F&O trading workstation, Trading Members must flag every order as either proprietary or client using the Pro/Cli indicator provided on the order entry screen.
   • Pro: Indicates trades executed on the Trading Member's own account.
   • Cli: Indicates trades executed on behalf of a registered client (requiring a unique client code).

2. Rules for Calculating Open Positions:

   • Proprietary Positions (Net Basis): Proprietary buy and sell quantities in a contract are netted off against each other.
     • Proprietary Net Position = Total Proprietary Buy Quantity - Total Proprietary Sell Quantity
   • Client Positions (Gross Basis): Positions of individual clients cannot be netted off against one another. Each client's position is calculated on a net basis (Buy - Sell), and then all individual client net long and short positions are aggregated on a gross basis.
     • Client Net Position = Client Buy Quantity - Client Sell Quantity
     • Total Client Open Position = Sum of Client Open Long Positions + Sum of Client Open Short Positions

3. Trading Member (TM) Total Open Position Formula:

   • TM Total Open Position = Proprietary Net Position + Sum of Individual Client Open Long Positions + Sum of Individual Client Open Short Positions

4. Clearing Member (CM) Total Open Position Formula:

   • CM Total Open Position = Aggregated Open Positions of all affiliated TMs + Aggregated Open Positions of all Custodial Participants (CPs) clearing through the CM

8.2.2 Numerical Illustration 1: Trading Member Open Position Calculation (TM Madanbhai)

To understand how open positions are carried forward and calculated across trading days, consider the following numerical example from the source workbook involving Trading Member Madanbhai, who trades for himself (Proprietary) and two clients (Client A and Client B).

Day 1 Trading Activity

1. Proprietary Trade Details (Day 1)

• Buy Trades: 200 units @ Rs. 1000
• Sell Trades: 400 units @ Rs. 1010
• Proprietary Net Position Calculation:
  • Proprietary Net Position = 200 - 400 = -200 (200 units Short)

2. Client Trade Details (Day 1)

• Client A:
  • Buy Open: 400 units @ Rs. 1109
  • Sell Close: 200 units @ Rs. 1000
  • Client A Net Position = 400 - 200 = +200 (200 units Long)
• Client B:
  • Sell Open: 600 units @ Rs. 1100
  • Buy Close: 200 units @ Rs. 1099
  • Client B Net Position = -600 + 200 = -400 (400 units Short)

Summary Table 8.1 & 8.2: TM Madanbhai Day 1 Position

Day 1 Total TM Open Position

• Proprietary Net Position = 200 units Short
• Gross Client Open Positions = 200 units (Client A Long) + 400 units (Client B Short) = 600 units
• TM Madanbhai Total Open Position (Day 1) = 200 + 600 = 800 units

Day 2 Trading Activity (Positions Carried Forward)

Assuming the open positions from Day 1 are carried forward to Day 2, and the exact same trading activity occurs on Day 2:

1. Cumulative Proprietary Position (End of Day 2)

• Day 1 Brought Forward Proprietary Net Position = 200 Short
• Day 2 Proprietary Trades Net = 200 Buy - 400 Sell = 200 Short
• End of Day 2 Proprietary Net Position = 200 Short + 200 Short = 400 units Short

2. Cumulative Client Positions (End of Day 2)

• Client A:
  • Day 1 Brought Forward Net Position = 200 Long
  • Day 2 Net Position = 200 Long
  • End of Day 2 Client A Net Position = 200 Long + 200 Long = 400 units Long
• Client B:
  • Day 1 Brought Forward Net Position = 400 Short
  • Day 2 Net Position = 200 Short
  • End of Day 2 Client B Net Position = 400 Short + 200 Short = 600 units Short

Summary Table 8.3 & 8.4: Cumulative Positions at End of Day 2

Day 2 Total TM Open Position

• Proprietary Cumulative Net Position = 400 Short
• Client A Cumulative Net Position = 400 Long
• Client B Cumulative Net Position = 600 Short
• TM Madanbhai Total Open Position (Day 2) = 400 + 400 + 600 = 1400 units

8.2.3 Numerical Illustration 2: Clearing Member Position Aggregation (Table 8.5)

To see how a Clearing Member (CM) aggregates open positions across multiple Trading Members, consider a CM clearing for two Trading Members (TM ABC and TM PQR), each handling two clients.

Breakdown of Trading Member Trades

1. Trading Member ABC

• Proprietary: Buy = 4000, Sell = 2000 -> Net Proprietary = +2000 (Long)
• Client 1: Buy = 3000, Sell = 1000 -> Net Client 1 = +2000 (Long)
• Client 2: Buy = 4000, Sell = 2000 -> Net Client 2 = +2000 (Long)
• TM ABC Aggregated Position:
  • Long Position = 2000 (Pro) + 2000 (Client 1) + 2000 (Client 2) = 6000 Long
  • Short Position = 0 Short

2. Trading Member PQR

• Proprietary: Buy = 2000, Sell = 3000 -> Net Proprietary = -1000 (1000 Short)
• Client 1: Buy = 2000, Sell = 1000 -> Net Client 1 = +1000 (1000 Long)
• Client 2: Buy = 1000, Sell = 2000# Chapter 8: Clearing and Settlement (Part 1 of 3)

8.0 Introduction to Clearing and Settlement

The National Securities Clearing Corporation Limited (NSCCL) is responsible for undertaking the clearing and settlement of all derivative contracts executed on the Futures and Options (F&O) segment of the National Stock Exchange of India Limited (NSE). Beyond operational processing, NSCCL acts as the legal counterparty to all F&O trades, guaranteeing financial settlement through the legal principle of novation.

The clearing and settlement framework rests on three primary operational pillars:

1. Clearing: Working out open positions and financial obligations of clearing members.
2. Settlement: Performing cash-settlement flows for daily mark-to-market profits/losses and final exercise values.
3. Risk Management: Enforcing real-time margin requirements, position monitoring, and collateral discipline.

8.1 Clearing Entities

NSCCL executes clearing and settlement functions in collaboration with primary clearing participants and banking intermediaries.

8.1.1 Clearing Members (CMs)

Clearing Members are responsible for settling trades with NSCCL, maintaining margin requirements, and ensuring client obligations are fulfilled. In the F&O segment, Clearing Members are categorized into three distinct types:

• Self-Clearing Members (SCM): Members who clear and settle trades executed by themselves only, either on their own proprietary account or on behalf of their registered clients. They cannot clear trades for other Trading Members.
• Trading Member-cum-Clearing Members (TM-CM): Members who clear and settle their own proprietary and client trades, and additionally clear and settle trades for other Trading Members (TMs).
• Professional Clearing Members (PCM): A special category of clearing members who are not Trading Members of the exchange (e.g., banks and custodians). PCMs exclusively clear and settle trades executed by affiliated Trading Members.

Additional Security Deposit Requirement

Clearing members clearing trades for other Trading Members (TM-CMs and PCMs) are required to bring in additional security deposits with NSCCL for every Trading Member whose trades they undertake to clear and settle.

8.1.2 Clearing Banks

Funds settlement in the F&O segment is executed through NSCCL-designated Clearing Banks.

• Account Opening Rule: Every Clearing Member must open a dedicated F&O bank account with an NSCCL-designated Clearing Bank.
• Operational Role: All daily cash flows—such as mark-to-market losses and gains, option premiums, exercise obligations, and margin payments—are automatically debited or credited through these designated accounts.

8.2 Clearing Mechanism

The clearing mechanism determines the open positions and net obligations of clearing members. These positions form the basis for exposure limits and daily margin calculations.

8.2.1 Rules for Calculating Open Positions

During order entry on the trading workstation, Trading Members must flag each order as proprietary or client using the Pro/Cli indicator:

• Pro: Proprietary trades on the Trading Member's own account.
• Cli: Client trades executed on behalf of constituents.

Netting vs. Gross Aggregation

1. Proprietary Positions (Net Basis): Calculated on a net basis for each contract by subtracting total sell quantity from total buy quantity.
2. Client Positions (Gross Basis): Calculated by taking the net position of each individual client (Buy minus Sell) and aggregating all client net long and net short positions on a gross basis without offsetting across clients.

Single-Line Open Position Formulas

• Proprietary Net Position = Proprietary Buy Quantity - Proprietary Sell Quantity
• Client Net Position = Individual Client Buy Quantity - Individual Client Sell Quantity
• TM Total Open Position = Proprietary Net Position + Sum of Individual Client Open Long Positions + Sum of Individual Client Open Short Positions
• CM Total Open Position = Sum of Open Positions of all affiliated TMs + Sum of Open Positions of all Custodial Participants (CPs) clearing through the CM

8.2.2 Numerical Illustration 1: Trading Member Open Position Calculation (TM Madanbhai)

To illustrate how positions carry forward across trading days, consider Trading Member Madanbhai who trades on proprietary account and for two clients (Client A and Client B).

Day 1 Position Determination

1. Proprietary Activity

• Trades: Bought 200 units @ Rs. 1000, Sold 400 units @ Rs. 1010
• Proprietary Net Position = 200 - 400 = -200 (200 units Short)

2. Client A Activity

• Trades: Bought 400 units @ Rs. 1109 (Open), Sold 200 units @ Rs. 1000 (Close)
• Client A Net Position = 400 - 200 = +200 (200 units Long)

3. Client B Activity

• Trades: Sold 600 units @ Rs. 1100 (Open), Bought 200 units @ Rs. 1099 (Close)
• Client B Net Position = 200 - 600 = -400 (400 units Short)

Summary Table: TM Madanbhai Day 1 Open Positions

• Total Open Position for TM Madanbhai (Day 1) = 200 (Proprietary Net Short) + 200 (Client A Long) + 400 (Client B Short) = 800 units.

Day 2 Position Determination (Carried Forward)

Assuming Day 1 positions are carried forward to Day 2, and identical trading activity occurs on Day 2:

1. Proprietary Position at End of Day 2

• Day 1 Position = 200 Short
• Day 2 Activity = 200 Buy - 400 Sell = 200 Short
• Cumulative Proprietary Position = 200 Short + 200 Short = 400 units Short

2. Client A Position at End of Day 2

• Day 1 Position = 200 Long
• Day 2 Activity = 200 Long
• Cumulative Client A Position = 200 Long + 200 Long = 400 units Long

3. Client B Position at End of Day 2

• Day 1 Position = 400 Short
• Day 2 Activity = 200 Short
• Cumulative Client B Position = 400 Short + 200 Short = 600 units Short

Summary Table: TM Madanbhai End of Day 2 Open Positions

• Total Open Position for TM Madanbhai (Day 2) = 400 (Proprietary) + 400 (Client A) + 600 (Client B) = 1400 units.

8.2.3 Numerical Illustration 2: Clearing Member Position Determination

Consider a Clearing Member (CM) clearing for two Trading Members (TM ABC and TM PQR).

Table 8.5: Determination of Open Position of a Clearing Member

• CM Net Long Open Position = 6000 (TM ABC) + 1000 (TM PQR Client 1) = 7000 units.
• CM Net Short Open Position = 1000 (TM PQR Proprietary) + 1000 (TM PQR Client 2) = 2000 units.

Key Takeaways & Exam Points

• Novation: NSCCL acts as the legal counterparty to every trade, guaranteeing financial settlement.
• Clearing Entities: SCM (clears own/client trades), TM-CM (clears own + other TMs' trades), PCM (non-TM clearing for TMs).
• Additional Security Deposit: TM-CMs and PCMs must provide additional collateral per TM cleared.
• Clearing Banks: All members must maintain an account with an NSCCL-designated clearing bank.
• Position Netting Rules: Proprietary positions are netted (Buy - Sell), while client positions are aggregated on a gross basis without offsetting across clients.
