NISM Series I: Chapter VI Study Notes – Clearing, Settlement, and Risk Management in Currency Futures
1. Introduction to Clearing and Settlement
The post-trade infrastructure of exchange-traded currency derivatives relies on two core processes to ensure transaction integrity and eliminate systemic default risks: Clearing and Settlement.
- Clearing is defined as the process of computing the open positions and corresponding financial obligations of clearing members within the trading system. It involves the systematic consolidation of trades to establish what each participant owes or is owed.
- Settlement refers to the actual performance of the contract, which is honoring the pay-in or pay-out obligations. While clearing calculates the obligations, settlement is the physical or electronic exchange of funds to fulfill those obligations.
2. Key Clearing Entities
The clearing system consists of specialized intermediaries that manage risk, execute funds transfer, and guarantee the performance of every contract.
A. Clearing Members (CMs)
Clearing Members are direct members of the Clearing Corporation. They are responsible for risk management, trade confirmation, and facilitating settlement. Within the currency derivatives segment, they are divided into different categories:
- Trading-cum-Clearing Member (TCM): A member holding the right to trade on their own account (proprietary trading) as well as on behalf of their clients. A TCM can clear and settle their own trades, as well as those executed for their clients, through the Clearing House.
- Professional Clearing Member (PCM): A clearing member who does not hold trading rights on the exchange (i.e., they are not Trading Members). PCMs are typically banks or custodial institutions that clear and settle trades executed by other Trading Members (TMs) and institutional participants.
- Clearing Members (CMs) General Role: They carry out risk management activities and conduct confirmations or inquiries of participant trades directly through the trading system.
B. Clearing Banks
All monetary settlements are processed through designated Clearing Banks.
- To facilitate seamless funds transfer, every clearing member is mandatorily required to open a separate, dedicated bank account with a Clearing Corporation-designated clearing bank specifically for the Currency Derivatives segment.
- All pay-in and pay-out obligations are routed through these accounts.
3. The Clearing Mechanism & Position Calculations
The clearing mechanism focuses on calculating the exact open positions and financial exposure of clearing members, which is subsequently used for exposure and daily margin assessments.
A. Position Aggregation Chain
The open positions of a Clearing Member (CM) are determined by aggregating the open positions of all the Trading Members (TMs) and custodial participants who clear their trades through that specific CM.
A Trading Member’s (TM) open position is calculated by summing their proprietary open positions and their clients' open positions.
B. The Proprietary vs. Client Position Netting Rules
There is a fundamental regulatory distinction in how proprietary trades and client trades are netted:
- Proprietary Positions (Pro): These represent the TM's own trading account. Proprietary positions are calculated on a net basis (Buy Position minus Sell Position) for each contract.
- Client Positions (Cli): These represent trades executed on behalf of clients. Client positions are arrived at by summing the net positions of each individual client.
- Critical Rule: Positions are only netted within each individual client's account; they are NEVER netted across different clients. Instead, individual client net positions are added up cumulatively.
C. Trading Member Position Formula
The open position of a Trading Member is determined using the following simple line formula:
\[\text{TM's Open Position} = \text{Proprietary Net Position} + \text{Client Open Long Position} + \text{Client Open Short Position}\]
D. Order Identification (Pro vs. Cli Indicator)
To ensure compliance with these netting rules, TMs must clearly identify the nature of every order at the time of entry. The trading system provides a 'Pro/Cli' indicator on the order entry screen, where:
- 'Pro' indicates proprietary orders entered on the trading member's own account.
- 'Cli' indicates orders entered on behalf of a client.
4. The Settlement Mechanism
Settlement in currency futures is structured around two distinct operational phases: Daily Mark-to-Market (MTM) Settlement and Final Settlement.
A. Daily Mark-to-Market (MTM) Settlement
At the end of each trading day, all live futures contracts for every member are marked-to-market to the daily settlement price of the relevant futures contract. The closing price is calculated as the last half-hour volume-weighted average price of the contract.
Depending on the status of the contracts, MTM profits or losses are computed as follows:
| Position Type | MTM Profit / Loss Computation Basis |
|---|---|
| Squared Off Positions | Calculated as the difference between the Buy Price and the Sell Price of the contracts executed and closed during the day. |
| Positions Not Squared Off (New Open) | Calculated as the difference between the Trade Price and the Day’s Daily Settlement Price for contracts executed during the day but left open. |
| Brought Forward (B/F) Positions | Calculated as the difference between the Previous Day’s Daily Settlement Price and the Current Day’s Daily Settlement Price for existing positions carried over. |
Daily MTM losses must be paid in (debited), and daily MTM gains are paid out (credited) to the clearing member's bank account.
B. Final Settlement for Futures
On the last trading day (expiry day) of a contract, the final settlement is executed:
- Expiry Date: Occurs two working days prior to the final settlement date. Trading ceases on this day.
- Final Settlement Price: The final settlement of currency futures contracts is settled in cash based on the official RBI reference rate.
- Final Settlement Date (Value Date): The last business day of the month is the final value/settlement date.
- Cash Settlement Timeline: The resulting profit or loss from the final settlement is debited or credited to the clearing member's clearing bank account on the T+2 working day following the last trading day (expiry day) of the contract.
5. Risk Management & Margin Requirements
Because futures contracts are leveraged financial instruments, exchanges enforce a strict risk management framework to prevent systemic defaults during high-volatility events. Margins serve as a financial safety net and act as a deterrent against excessive speculation.
| Component | Treatment |
|---|---|
| Total Liquid Assets (CM) | Starting point |
| Less: Initial Margin | Deduct |
| Less: Extreme Loss Margin | Deduct |
| Liquid Net Worth | Total Liquid Assets − Initial Margin − Extreme Loss Margin |
| Minimum Requirement | ₹50 Lakh |
A. Initial Margin
- The initial margin is the security deposit required from a member to allow them to take trading exposure.
- It is calculated based on the worst-case loss of an individual client's portfolio across various simulated scenarios of price changes.
- The initial margin must be deposited in the margin account at the time a futures contract is first entered into.
B. Portfolio-Based Margin (SPAN Methodology)
- The Clearing Corporation adopts the Standard Portfolio Analysis of Risk (SPAN) methodology.
- SPAN takes an integrated view of risk by evaluating the entire portfolio of an individual client, comprising positions in futures contracts across different maturities, rather than looking at contracts in isolation.
C. Real-Time Margin Computation
The calculation of the worst-scenario loss under SPAN is performed dynamically in two stages:
- Stage 1 (Portfolio Valuation): The portfolio is valued under various simulated price-change scenarios.
- Stage 2 (Contract Value Application): These scenario-based contract values are applied to actual portfolio positions on a real-time basis to compute the overall portfolio value and required initial margin.
D. Calendar Spread Margin
- A calendar spread involves holding offsetting long and short positions in different expiry months of the same underlying asset.
- For calendar spread positions, the extreme loss margin is charged on one-third of the mark-to-market value of the far-month contract.
E. Extreme Loss Margin
- Extreme loss margin is designed to cover risk exposures beyond the worst-case loss scenario covered by the initial margin.
- It is calculated as a fixed percentage of the mark-to-market value of the Gross Open Position and is directly deducted from the liquid assets of the Clearing Member.
F. Liquid Net Worth and Liquid Assets
- Liquid Assets: These are maintained separately in the currency futures segment of the Clearing Corporation to meet margin and settlement obligations.
- Liquid Net Worth: Calculated as the liquid assets of the clearing member after adjusting for (deducted) both the Initial Margin and Extreme Loss Margin requirements.
- Minimum Requirement: The adjusted liquid net worth of a clearing member must be at least Rs. 50 lacs at all points in time.
