7.1 Clearing and Settlement Mechanism

The clearing and settlement mechanism is the core infrastructure ensuring financial integrity and counterparty confidence in the exchange-traded derivatives market.

                        Legal Novation Occurs Here

The Concept of Legal Novation

In an exchange-traded derivatives market, the Clearing Corporation (CC) acts as the Central Counterparty (CCP) for all trades executed on the exchange:

• Legal Novation: Once a trade is matched on the exchange platform, the original contract between the buyer and the seller is extinguished and replaced by two new contracts:
  1. The Clearing Corporation becomes the buyer to every seller.
  2. The Clearing Corporation becomes the seller to every buyer.
• Settlement Guarantee: Because of novation, market participants are insulated from the credit risk or default risk of their direct counterparties. If a clearing member defaults on its obligation, the Clearing Corporation fulfills the payment or delivery obligations using its risk containment resources and the Core Settlement Guarantee Fund (Core SGF).

Bilateral Netting vs. Multilateral Netting

• Bilateral Netting: Offsetting obligations between two specific counterparties.
• Multilateral Netting: All buy and sell transactions executed by a Clearing Member across all trading members and clients are netted down to a single net payable or net receivable obligation vis-à-vis the Clearing Corporation for each settlement cycle. This dramatically reduces liquidity requirements and systemic risk.

7.2 Entities in Clearing and Settlement of ETCD

The clearing and settlement ecosystem consists of several specialized institutions and market participants:

7.3 Interoperability of Clearing Corporations

Historically, trades executed on an exchange could only be cleared by that exchange's affiliated clearing corporation. Under SEBI's Interoperability Framework:

1. Choice of Clearing Corporation: A Clearing Member can choose a single Clearing Corporation of its choice to clear and settle trades executed across multiple recognized stock exchanges (NSE, BSE, MSEI).
2. Capital Efficiency: Margins across trades executed on different exchanges are consolidated and netted at the designated clearing corporation, significantly reducing redundant collateral locks and operational costs.
3. Cross-Exchange Risk Aggregation: The interoperable clearing corporation monitors unified position limits and total exposure across exchanges in real time.

7.4 Clearing Mechanism & Trade Capture

1. Trade Capture: All matched orders on the exchange trading engine are transmitted in real time to the clearing system.
2. Trade Confirmation / Custodial Allocation: Institutional trades executed with a Custodial Participant (CP) code must be confirmed by the respective Custodian within the SEBI-stipulated cut-off time on trade day (T-Day). If rejected or unconfirmed, the obligation devolves onto the executing Trading Member.
3. Netting of Positions:
   • Proprietary Account: Netted at the Trading/Clearing Member level.
   • Client Accounts: Positions are maintained on a gross basis across different clients. Netting is permitted within the same client's account across trades, but positions of Client A cannot offset positions of Client B.

7.5 Determination of Settlement Obligations

In Exchange-Traded Currency Derivatives, settlement obligations are categorized into:

1. Daily Mark-to-Market (MTM) Settlement Obligations (Futures):
   • Calculated daily at the end of the trading session.
   • Computed as the difference between the transaction price (or previous day's settlement price) and the current day's Daily Settlement Price (DSP).
   • Settled in cash on T+1 day morning in Indian Rupees (INR).
2. Premium Settlement Obligations (Options):
   • Option buyer pays premium; option seller receives premium.
   • Settled on a gross basis on T+1 day morning in INR.
3. Final Settlement Obligations:
   • For Futures: Cash settled on the expiry date against the official FBIL Reference Rate.
   • For Options: In-the-money (ITM) options are automatically exercised and cash settled against the FBIL Reference Rate on the expiry date.

7.6 Position Limits

To prevent market manipulation and undue concentration of risk, SEBI and RBI have mandated multi-tiered position limits across contracts.

A. Position Limits across Market Participants

[!NOTE] Bank Trading Members Exception: For scheduled commercial banks authorized by RBI as Trading Members, the gross open position across all contracts in USD/INR shall not exceed 15% of total Open Interest or USD 1 Billion, whichever is higher.

B. Consolidated Single INR Limit for Proprietary Positions

Stock brokers must ensure that all proprietary positions created in FCY-INR pairs remain within a consolidated single limit:

• Non-Bank Stock Brokers: Higher of 15% of total Open Interest across all FCY-INR pairs or USD 100 Million.
• Bank Stock Brokers: Higher of 15% of total Open Interest across all FCY-INR pairs or USD 200 Million.

C. Single Limit Across All Currency Pairs Combined (RBI Directive)

• Market participants (users) may take positions (long or short) up to a single limit of USD 100 Million equivalent across all currency pairs involving INR, combined across all recognized exchanges, without the requirement of presenting physical documentary proof of underlying exposure.
• Users intending to take positions beyond USD 100 Million equivalent must designate an Authorised Dealer (AD) Category I Bank / Custodian to monitor exposure against documented underlying commercial transactions.

7.7 Settlement Process: Daily & Final

1. Daily Mark-to-Market (MTM) Settlement for Futures

Daily settlement price is the volume-weighted average price (VWAP) of the contract during the last 30 minutes of trading, or a theoretical price determined by the Clearing Corporation if trading volume is insufficient.

$$ ext{Daily MTM Cash Flow} = ( ext{Current Settlement Price} - ext{Previous Price}) imes ext{Lot Size} imes ext{Number of Contracts}$$

Worked Numerical Example: USD/INR Futures MTM

• A trader buys 10 lots of USD/INR futures on Monday at ₹84.10. (Lot size = 1,000 USD).
• Monday Settlement Price = ₹84.25. $$ ext{MTM Gain} = (84.25 - 84.10) imes 1,000 imes 10 = +₹1,500 \quad ext{(Credit)}$$
• Tuesday Settlement Price = ₹83.95. $$ ext{MTM Loss} = (83.95 - 84.25) imes 1,000 imes 10 = -₹3,000 \quad ext{(Debit)}$$
• The debit of ₹3,000 must be paid into the clearing bank account by Tuesday morning (T+1).

MTM Settlement for Cross-Currency Pairs

For cross-currency pairs (e.g., EUR/USD, GBP/USD, USD/JPY):

1. The daily MTM profit or loss is first calculated in the quote currency (e.g., USD for EUR/USD).
2. The resulting foreign currency profit/loss is converted into Indian Rupees (INR) using the official FBIL USD/INR Reference Rate of that day.
3. The member's account is credited or debited strictly in Indian Rupees.

2. Settlement of Option Contracts

• Daily Premium Settlement: The buyer of an option pays the premium, and the seller receives the premium. This is settled on a T+1 basis in cash (INR).
• Final Settlement of Options:
  • Exchange-traded currency options are European Style. Exercise is permitted only on the expiry date.
  • Automatic Exercise: All In-the-Money (ITM) options are automatically exercised by the Clearing Corporation on the expiry date.
  • Cash Settlement: Settlement value is calculated as the difference between the Strike Price and the final FBIL Reference Rate: $$ ext{Call Option Final Value} = \max(0, ext{FBIL Rate} - ext{Strike Price}) imes ext{Lot Size} imes ext{Contracts}$$ $$ ext{Put Option Final Value} = \max(0, ext{Strike Price} - ext{FBIL Rate}) imes ext{Lot Size} imes ext{Contracts}$$
  • Out-of-the-Money (OTM) and At-the-Money (ATM) options expire worthless without any exercise obligation.

7.8 Funds Settlement Mechanism

• Funds settlement takes place electronically through accounts maintained with designated Clearing Banks.
• Pay-in Time: Clearing members must ensure sufficient clear funds in their clearing accounts by 10:30 AM on T+1 day.
• Pay-out Time: Once pay-in is completed and verified, the Clearing Corporation releases pay-out of funds to members with net receivable positions by 11:00 AM on T+1 day.

7.9 Comprehensive Risk Management Framework

The risk management system operates on real-time online monitoring to contain counterparty default risk:

┌─────────────────────────────────────────────────────────────────┐
│                  TOTAL MARGIN REQUIREMENT                       │
├────────────────────────────────┬────────────────────────────────┤
│      Initial Margin (SPAN)     │   Extreme Loss Margin (ELM)    │
│  Portfolio VaR (99% Conf.)     │   Tail Risk Coverage           │
├────────────────────────────────┴────────────────────────────────┤
│                   + Calendar Spread Margin                      │
│               + Net Option Value (Options Only)                 │
└─────────────────────────────────────────────────────────────────┘

1. Initial Margin (SPAN System)

Initial margin is calculated using the Standard Portfolio Analysis of Risk (SPAN®) system developed by CME and adapted for Indian markets:

• Portfolio-Based Margining: SPAN analyzes the overall portfolio of futures and options contracts to calculate the maximum potential one-day loss across 16 risk scenarios.
• Scenario Parameters: Evaluates simulated shifts in underlying currency prices (Price Scan Range) and implied volatility (Volatility Scan Range).
• Confidence Level: Designed to cover price movements with a 99% statistical confidence interval over a 1-day or 2-day margin period of risk.

2. Extreme Loss Margin (ELM)

ELM acts as a buffer beyond standard SPAN margins to protect against extreme outlier market moves ("tail risk"):

• Calendar Spread ELM: In calendar spreads, ELM is levied on only one-third (1/3rd) of the mark-to-market value of the far-month contract.
• Option Buyer Exemption: Buyers of options have limited risk (maximum loss is the premium already paid), so NO ELM or SPAN margin is levied on long option positions.

3. Eligible Collateral & Liquid Assets Ratio (50:50 Rule)

Clearing Members must deposit collateral to cover their margin requirements. The collateral pool must strictly adhere to the 50:50 Cash Equivalent vs. Non-Cash Collateral rule:

1. Cash Equivalent Collateral (Minimum 50%):
   • Cash in INR.
   • Fixed Deposit Receipts (FDRs) from approved banks.
   • Bank Guarantees (BGs) from approved commercial banks.
   • Treasury Bills and Sovereign Gold Bonds (SGBs).
2. Non-Cash Collateral (Maximum 50%):
   • Approved equity shares (Group I shares subject to prescribed haircuts, typically 20%–30%).
   • Government of India (GoI) dated securities.
   • Units of liquid mutual funds or exchange-traded funds (ETFs).

4. Risk Reduction Mode (RRM)

• When a Clearing Member's collateral utilization crosses 90% of its effective liquid net worth, the trading system automatically places the member into Risk Reduction Mode (RRM).
• Under RRM:
  • Fresh risk-increasing orders are automatically blocked.
  • Only square-off / risk-reducing orders or order cancellations are accepted.
• If utilization touches 100%, the member is automatically disabled from entering any trades until additional collateral is deposited.

7.10 Margin Collection, Peak Margins & Client Collateral System

1. Mandatory Upfront Margin Collection

Trading members must collect both Initial Margin and ELM from clients upfront before executing trades. Collecting margins on T+1 is prohibited.

2. Peak Margin Reporting Mechanism

To prevent brokers from offering excessive intraday leverage:

• The Clearing Corporation takes 4 random intraday snapshots of client positions during the trading day.
• The highest margin requirement across these 4 snapshots is identified as the Peak Margin.
• Brokers must report margin collection against this peak figure. Any shortfall in peak margin collection attracts a mandatory short-collection penalty.

3. Client Collateral Pledge and Re-pledge Framework

To prevent misuse of client securities by brokers:

• No Title Transfer: Securities deposited by clients as collateral can no longer be transferred to the broker's demat account.
• Margin Pledge: The client creates a formal "Margin Pledge" in favor of the broker directly from their own demat account.
• Re-Pledge to CC: The broker can re-pledge these securities to the Clearing Member, who in turn re-pledges them to the Clearing Corporation.
• The beneficial ownership of the securities remains with the client at all times, ensuring dividends, corporate actions, and voting rights stay intact.
• Brokers are strictly prohibited from using one client's collateral to fund margin requirements of another client or proprietary trades.

7.11 Core Settlement Guarantee Fund (Core SGF)

Each Clearing Corporation maintains a ring-fenced Core Settlement Guarantee Fund (Core SGF) to guarantee trade settlement in the event of clearing member defaults.

Minimum Required Corpus (MRC) Contributions

• Clearing Corporation: Minimum 50% of MRC.
• Stock Exchange: Minimum 25% of MRC.
• Clearing Members: Maximum 25% of MRC (assessed based on risk score).

The SEBI Default Waterfall Structure

If a Clearing Member defaults, the deficit is absorbed strictly according to the statutory 8-stage Default Waterfall:

[Stage 1] Defaulter's Own Assets & Collaterals (including primary Core SGF contribution)
   │
[Stage 2] Insurance Proceeds (if any policy covers the default)
   │
[Stage 3] Clearing Corporation's Own Dedicated Capital (5% of segment MRC)
   │
[Stage 4] Segment Core SGF:
          I. Penalties collected in the segment
          II. CC Contribution (at least 25% of segment MRC)
          III. Pro-rata distribution: Balance CC contribution, Stock Exchange contribution,
               and non-defaulting members' primary contributions
   │
[Stage 5] Proportion of Remaining CC Resources (excluding Core SGFs of other segments and ₹100 Cr)
   │
[Stage 6] Inter-segment Transfer of CC/SE contributions from other segments (with SEBI approval)
   │
[Stage 7] Capped Additional Contribution by Non-Defaulting Members (capped at 2x primary contribution)
   │
[Stage 8] Pro-rata Haircut on Net Settlement Pay-outs to remaining non-defaulting members

7.12 Cyber Security & Cyber Resilience Framework (CSCRF)

Recognizing that trading, clearing, and settlement are digitally interconnected, SEBI notified the unified Cyber Security & Cyber Resilience Framework (CSCRF), effective in phased stages starting January 1, 2025.

1. Market Infrastructure Institutions (MIIs)

Under CSCRF, the following entities are classified as systemically critical MIIs subject to the highest security tier:

1. Stock Exchanges
2. Clearing Corporations
3. Depositories (NSDL, CDSL)
4. KYC Registration Agencies (KRAs)
5. Qualified Registrars and Transfer Agents (QRTAs)
