SEBI Proposed Changes To Derivative Trading Rules

SEBI Proposed Changes To Derivative Trading Rules

In response to the explosive growth in options trading, India's markets regulator, the Securities and Exchange Board of India (SEBI), is considering a series of significant tweaks to its derivative trading rules. These proposed changes aim to address the potential risks arising from this rapid expansion, particularly among retail investors. The new rules could include higher margins for options contracts and more detailed disclosures, reflecting SEBI's commitment to ensuring market stability and investor protection.

Surge in Options Trading

Trading in index and stock options has seen unprecedented growth in India over the past few years. This surge has been largely driven by retail investors, resulting in the notional value of index options more than doubling in 2023-24 to an astounding $907.09 trillion. Such rapid expansion has raised alarms among market participants and government officials alike. India's federal finance minister recently warned that unchecked growth in retail trading of futures and options could pose significant challenges not only for the markets but also for investor sentiment and household finances.

Proposed Regulatory Changes

SEBI's proposed regulatory changes are being developed after a series of meetings with exchanges, brokers, and fund houses over the past four months. The first major step under consideration is linking options trading with the underlying cash volumes of a stock. This measure aims to control the build-up of open positions in less liquid stocks. If there is an excessive build-up of options positions relative to cash volumes, the margin requirement for trading options would increase.

Additionally, SEBI is looking to increase disclosures on index and stock options contracts. Currently, only options activity and open interest are disclosed. The new rules would require more comprehensive disclosures to provide a clearer picture of the risks involved.

Addressing Market Concerns

The ratio of options volumes to underlying cash trading volumes in India is approximately four times, compared to a global average of 5-15 times. This discrepancy has raised concerns among regulators. In the United States, the derivatives to cash ratio is about nine times. By implementing these changes, SEBI aims to align India's market practices with global standards, thereby reducing potential risks. Furthermore, SEBI plans to suggest changes in transaction fees levied by exchanges on brokers. The current practice of charging lower transaction fees for brokers with high turnover may be replaced with a flat fee structure, regardless of turnover. This move could help level the playing field and ensure fairer market practices.

Protecting Retail Investors

Retail investors account for 35% of derivative trading in India, a significant portion compared to global standards. Of the 108 billion options contracts traded worldwide in 2023, 78% were on Indian exchanges. In April alone, 78% of trades on India's largest exchange, the National Stock Exchange, were by investors trading less than 1 million rupees ($11,969). This highlights the substantial involvement of small investors in the market.

To protect these investors, SEBI is considering measures to prevent excessive speculation and potential manipulation. One proposed measure is to increase the lot sizes of options contracts, which could deter very small investors from entering the market without fully understanding the risks involved. This is particularly pertinent given the government's reservations about the surge in zero-day options trading, a highly speculative strategy not yet available on Indian exchanges.

A Broader Perspective

The proposed changes are still in the discussion stage and will be subject to public consultation over the coming months. SEBI's focus is not just on mitigating risks to the financial system but also on safeguarding investor protection. According to Will Acworth, Senior Vice President, Data & Research, FIA, the real issue for the government and SEBI is ensuring that investors are adequately protected and informed. He equates buying options without fully understanding the product to gambling, underscoring the need for greater transparency and education.


SEBI's planned tweaks to derivative trading rules represent a proactive approach to managing the rapid growth in options trading. By introducing higher margins, increased disclosures, and potentially larger lot sizes, SEBI aims to create a more stable and transparent market environment. These changes, once implemented, could significantly impact the dynamics of the Indian derivatives market, fostering a safer and more informed trading landscape for all participants.

As the proposed changes move towards public consultation, it will be interesting to see how market participants and investors respond. The goal is clear: to balance growth with stability, ensuring that the Indian market remains robust and resilient in the face of rapid change.
