SEBI Introduces New Measures to Regulate Equity and Index Derivatives

The capital market regulator, the Securities and Exchange Board of India (SEBI) suggested a set of new rules aimed at tightening the regulation of derivatives trading. The proposals include linking market-wide position limits for single-stock derivatives to the liquidity in the cash markets, as well as implementing stricter criteria for index derivatives (excluding Nifty 50 and Sensex) to prevent market manipulation. These changes follow SEBI’s decision to raise entry barriers for derivatives trading in October 2024.

New Limits for Single-Stock Derivatives

SEBI’s proposal introduces market-wide position limits for single-stock derivatives. The limits would be capped at the lower of 15% of the free-float market capitalization or 60 times the average daily delivery value. This move is designed to ensure that derivatives positions are in line with the liquidity of the underlying cash markets, thereby reducing the risk of market manipulation.

Stricter Rules for Index Derivatives

In addition, SEBI suggested that index derivatives should only be offered if the underlying index contains at least 14 constituent stocks. This requirement aims to prevent over-reliance on a small number of heavy-weight stocks, which could distort the market. Furthermore, SEBI proposed that no single stock should have more than a 20% weight in any index, and the combined weight of the top three stocks should not exceed 45%. These measures are intended to maintain market balance and reduce manipulation risks.

Pre-Open Session Proposed for Futures Market

SEBI also recommended extending the pre-open session mechanism, currently used in the cash market, to the futures market. Initially, this will apply to current-month futures for both single stocks and indices, helping with price discovery and reducing excessive volatility.

Following Up on October 2024 Margin Increase

These proposals build upon SEBI’s October 2024 decision to raise margin requirements and restrict entry into the derivatives market. The tightening of rules is intended to better protect retail investors and minimize the influence of speculation on broader market trends.

Addressing Growing Concerns Over F&O Market Impact

Concerns about the impact of the futures and options (F&O) market on the cash market have grown, especially following the sharp market corrections in Indian equities after the record highs in September 2024. SEBI believes these proposed changes will help mitigate volatility driven by speculative activities.

Before implementing these changes, SEBI is inviting feedback from stakeholders, seeking input on how the new measures could affect the derivatives market and broader market stability. The regulator aims to align derivatives trading with the liquidity and integrity of the underlying stocks and indices.
