SEBI New Plan to Curb Equity Derivative Volatility and Market Manipulation
Introduction
SEBI New Plan : India’s stock markets have witnessed high volatility, especially after reaching record highs in September 2024. To address concerns of potential manipulation and excessive risk spillovers from the derivatives segment, the Securities and Exchange Board of India (SEBI) has proposed new regulations. These measures aim to ensure fair trading practices, reduce artificial stock movements, and prevent excessive speculative activities.
Why SEBI Is Introducing These Changes
SEBI has already taken steps in recent months to tighten the rules around equity derivatives. In October 2024, it introduced stricter entry barriers, making it more expensive for traders to participate in derivative trading. Now, SEBI has unveiled a fresh set of proposals designed to provide better oversight of open interest calculations, position limits, and index derivatives.
The main goals of these regulations include:
- Reducing artificial inflation of stocks entering the “ban period.”
- Curbing excessive speculation and market manipulation.
- Making position limits more reflective of market reality.
- Ensuring broader market stability by restructuring index derivative rules.
Key Changes Proposed by SEBI
1. Revised Open Interest Calculation
SEBI plans to change how open interest in single-stock derivatives is calculated. This will provide a clearer picture of actual market exposure and reduce artificial price movements caused by speculative trading.
2. New Position Limit Rules
Under the new proposal, the position limit will be:
- 15% of a stock’s free-float market capitalization OR
- 60 times the average daily delivery value, whichever is lower.
Currently, the limit is the lower of 20% of the free-float market cap or 30 times the daily average. This change aims to prevent market manipulation and ensure that no single trader or group has excessive control over a stock’s price movements.
3. Stricter Rules for Index Derivatives
SEBI has raised concerns about the correlation between cash and derivatives markets. It has proposed that only indices meeting specific criteria be allowed to have derivative contracts. These include:
- A minimum of 14 constituents in the index.
- The top three stocks should not hold more than 45% weight in the index.
- The top individual stock’s weight should not exceed 20%.
This move is aimed at preventing situations where a small number of stocks dominate an index, which can lead to price manipulation.
For example, the Nifty Bank Index currently has 12 constituents, with its top three stocks accounting for over 60% of its weight. SEBI’s new rules would require such indices to be restructured to dilute concentrated weightage.
4. Introduction of a Pre-Open Session for Futures
SEBI has also proposed a pre-open session for the futures market, similar to the cash market. This session would apply to both single-stock and index futures, helping to smoothen price discovery and reduce opening volatility.
How These Changes Will Impact the Market
For Retail and Institutional Investors
- Lower volatility: A more structured derivative market will mean fewer price swings, making investing less risky.
- Fairer trading environment: Tighter controls will prevent excessive speculation by big players, ensuring a level playing field for smaller investors.
- More predictable price movements: New position limits will reduce the chances of sudden, unexplained stock price movements.
For Traders and Speculators
- Higher compliance costs: Traders will have to adjust their strategies to comply with the new open interest calculations and position limits.
- Stricter index derivative regulations: The new rules will make it harder to manipulate indices with a concentrated stock weightage.

Conclusion
SEBI’s latest proposals reflect its commitment to protecting investors and maintaining market integrity. By curbing excessive speculation, preventing manipulation, and improving position limits, SEBI is taking proactive steps to make India’s stock market more stable and reliable.
For traders and investors, adapting to these new rules will be crucial. While some may find the restrictions challenging, the long-term benefits of a fairer and more transparent market outweigh the short-term inconveniences.
With these changes, India’s equity and derivatives markets are set to become more resilient, less volatile, and more trustworthy for investors of all sizes.
