National Stock Exchange of India Limited Regulations for the Futures & Options (F&O) Segment

The Futures & Options (F&O) segment of the National Stock Exchange of India Limited (NSE) is a highly regulated arena designed to promote transparency, protect investors, and ensure the orderly functioning of derivatives markets. This page outlines the key regulatory provisions, eligibility criteria, margin and positionlimit frameworks, and compliance expectations for participants operating in the NSE F&O segment.

1. Legal Foundations

All F&O activity on the NSE is governed by:

• The Securities and Exchange Board of India (SEBI) Derivatives Regulations, 2022 and subsequent amendments.
• The NSE Derivatives Trading Regulations (as notified from time to time).
• Relevant provisions of the Companies Act, 2013, and the Indian Contract Act, 1872.

These statutes empower SEBI to issue circulars, advisory notices, and enforcement orders that directly affect market participants.

2. Eligibility & Registration

2.1 Eligible Participants

• Members Registered brokers, clearing members, and subbrokers.
• Investors Individuals, HNI (HighNetWorth), corporate bodies, mutual funds, pension funds, and foreign institutional investors (FIIs).

2.2 Registration Process

5. Obtain a unique Client ID (CID) from the NSE after the broker forwards the documentation.

3. Margin Framework

Margin in the F&O segment is a combination of Initial Margin (IM), Exposure Margin (EM), and MarktoMarket (MTM) adjustments. The key objectives are to safeguard the clearinghouse and to mitigate systemic risk.

Margin Type	Purpose	Calculation Basis
Initial Margin (IM)	Collateral required to open a position.	Based on contract size, volatility, and price.
Exposure Margin (EM)	Additional safety net against extreme price moves.	Set as a fixed percentage of the contract value (usually 25%).
MarktoMarket (MTM)	Daily settlement of gains/losses.	Difference between previous settlement price and current price.

Margin rates are reviewed nightly by the NSEs Risk Management Division and may be revised on a quarterly basis in accordance with SEBIs guidelines.

4. Position Limits

Position limits are designed to prevent market manipulation and concentration of risk. Limits differ for individual and collective positions.

4.1 Individual Position Limits (IPL)

• For equity futures: 2000 contracts per client for a single underlying security.
• For index futures: 1500 contracts per client for a single index.
• For equity options: 3000 contracts on a single strike price.
• For commodity derivatives: Limits are set on a percommodity basis (e.g., 10,000 contracts for crude oil futures).

4.2 Collective Position Limits (CPL)

Collective limits refer to the sum total of positions held by all clients of a broker or a group of linked entities. These limits are typically 23 times higher than the individual limits and are monitored by NSEs Surveillance Department.

5. Delivery Obligations and Settlement

• Physical Settlement Applicable to certain commodity contracts where the underlying asset must be delivered on the expiry date.
• Cash Settlement Standard practice for equity index futures, equity options, and most equity derivatives. Settlement amount is based on the final settlement price (FSP) announced by NSE.
• All participants must maintain sufficient cash or securities in the demat account to meet the settlement obligations.
• Failure to deliver results in a default charge and may lead to suspension or termination of the clients trading privileges.

6. Surveillance, Reporting & Penalties
