Trading in India: understanding SEBI regulations and margin rules

The Indian capital markets, overseen by the Securities and Exchange Board of India (SEBI), have undergone significant structural reforms aimed at reducing systemic risk and protecting retail participants. For traders, particularly those involved in intraday and derivatives (F&O) segments, understanding these regulations is essential for capital preservation and compliance. We examine the current regulatory framework and the impact of the 'Peak Margin' regime.

The Peak Margin Regime: ending excessive leverage

One of the most impactful changes in recent years is the implementation of 'Peak Margin' rules. Previously, brokers could offer high intra-day leverage (sometimes up to 20x or 50x) by not reporting margins during the trading session. SEBI now requires clearing corporations to take four 'snapshots' of client positions at random intervals throughout the day.

• Upfront Margin: Traders must have 100% of the required margin (VAR+ELM) available in their account before executing a trade. There is no longer 'broker-funded' leverage for intraday trades beyond what is prescribed by the exchange.
• Penalty for Shortfall: If the peak margin snapshot shows a shortfall in the required funds, the clearing corporation imposes a penalty on the broker, which is typically passed on to the client.

Segregation of client funds and collateral

SEBI has mandated a strict segregation of client funds and securities. Brokers are no longer permitted to use one client's idle funds or securities to fund the margin requirements of another client or for their own proprietary trading. This is enforced through the 'Pledge/Re-pledge' system:

1. Direct Pledging: Securities remain in the client's own demat account. The client 'pledges' them in favor of the clearing corporation to get a margin benefit.
2. No Pooling of Funds: Idle cash in a trading account must be returned to the client's bank account at least once every quarter (or month, depending on the client's preference)—a process known as 'Running Account Settlement.'

The F&O Segment and Retail Restrictions

India has one of the world's most active retail derivatives markets. To curb excessive speculation by those who may not understand the risks, SEBI has introduced several measures:

• Contract Size: The minimum contract value for F&O is regularly adjusted to ensure it remains significant enough to discourage small retail participants from over-leveraging.
• Physical Settlement: Since 2019, all stock derivatives that are 'in the money' at expiry must be physically settled. This means you must either deliver or take delivery of the actual shares, which requires significant capital. Cash settlement is only available for index derivatives (Nifty, Bank Nifty).

Investing as an NRI (Non-Resident Indian)

NRIs must follow a specific path to trade in India. This involves opening a PIS (Portfolio Investment Scheme) account, a NRE/NRO bank account, and a dedicated demat account. NRIs are prohibited from intraday trading in stocks and can only trade in the delivery-based equity segment or F&O (with a custodial participant code).

We recommend that all participants in the Indian market prioritize compliance with these rules, as SEBI's automated surveillance systems are highly efficient at detecting and penalizing margin violations.
