Understanding SEBI’s Reversal: A New Dawn for F&O Trading

SEBI’s recent announcement marks a significant shift in its approach to regulating Futures and Options trading, particularly the contentious issue of weekly index option expiries. Previously, SEBI introduced stringent measures to curb speculative trading, such as reducing weekly expiries and increasing contract sizes. These steps aimed to protect retail investors from substantial losses, with SEBI’s data revealing that 91% of individual traders incurred net losses of ₹1.05 trillion in FY25. However, the regulator’s latest reversal responds to concerns raised by brokers, who fear that discontinuing weekly expiries could drastically reduce market volumes and liquidity.

This decision reflects SEBI’s commitment to balancing investor protection with market dynamism. By retaining weekly expiries, SEBI ensures that traders can continue leveraging short-term opportunities while introducing frameworks to minimize risks. This move is particularly significant for retail investors, who form a substantial portion of India’s derivatives market, and for brokers, whose revenues depend on trading volumes.

Why SEBI’s Decision Matters for Retail Investors

Retail investors have been at the heart of SEBI’s regulatory focus, given their significant participation in F&O trading. Since the pandemic, the Indian derivatives market has seen explosive growth, with nearly 80% of active demat accounts opened post-April 2020. However, this surge has come at a cost, with SEBI’s July 2025 study highlighting that 91% of retail traders faced losses in FY25, averaging ₹1.10 lakh per trader. The regulator’s initial measures, such as limiting weekly expiries to one per exchange and increasing contract sizes, aimed to curb this speculative frenzy.

The reversal on weekly expiries addresses brokers’ concerns that further restrictions could stifle market activity. By maintaining weekly expiries, SEBI ensures that retail investors retain access to short-term trading opportunities, which are popular for their potential for quick gains. However, SEBI is also exploring eligibility criteria to ensure that only experienced investors participate in high-risk F&O trading. This dual approach—preserving market access while enhancing risk management—could empower retail investors to trade more confidently.

Key Benefits for Retail Investors

Continued Access to Weekly Expiries: Retaining weekly index option expiries allows retail investors to capitalize on short-term market movements, which are often more predictable than long-term trends.
Enhanced Risk Management: SEBI’s proposed eligibility criteria aim to filter out inexperienced traders, reducing the likelihood of significant losses.
Improved Market Stability: By addressing brokers’ concerns, SEBI ensures that market volumes remain robust, providing liquidity that benefits retail traders.
Transparency and Protection: SEBI’s focus on transparent frameworks and investor protection measures fosters a safer trading environment.

Brokers’ Role in Shaping SEBI’s Policy

Brokers play a pivotal role in India’s stock market, facilitating trades and generating revenue from transaction volumes. On July 18, 2025, SEBI chief Tuhin Kanta Pandey met with top brokers to discuss the future of F&O trading. During this meeting, brokers expressed concerns over the potential discontinuation of weekly index option expiries, arguing that it would lead to a significant drop in trading volumes—potentially by 30-40%, as estimated by industry reports. This reduction could hurt their revenues and disrupt the market’s liquidity.

Brokers proposed several solutions to balance investor protection with market vitality:

Retaining Weekly Expiries: Brokers strongly advocated against discontinuing weekly expiries, emphasizing their importance for maintaining market activity.
Establishing Eligibility Criteria: They suggested setting clear criteria for F&O investors, such as experience or financial thresholds, to limit speculative trading by novices.
Reversing Trades to Mitigate Losses: Brokers recommended that exchanges should have mechanisms to reverse trades in extreme cases, preventing losses like those seen in the Jane Street case.
Reducing Trading Costs: To make the market more competitive, brokers proposed lowering transaction costs, aligning India’s market with global standards like Nasdaq.
Broadening Indices: They suggested expanding the scope of indices like Bank Nifty to reduce manipulation risks and enhance market resilience.

These suggestions reflect brokers’ dual objectives: protecting their revenue streams while supporting SEBI’s goal of safeguarding retail investors. SEBI’s decision to retain weekly expiries indicates that the regulator values this input, aiming to create a “win-win” scenario for all stakeholders.

The Impact on Market Dynamics

SEBI’s reversal on weekly expiries is poised to have far-reaching effects on India’s stock market. The derivatives market, particularly index options, has grown exponentially, with turnover exceeding India’s nominal GDP in FY24. However, this growth has been accompanied by concerns over excessive speculation, especially on expiry days, when volumes can be 350 times higher than the underlying cash market. This imbalance has raised fears of market manipulation and systemic risks, prompting SEBI’s initial regulatory tightening.

By retaining weekly expiries, SEBI aims to preserve the market’s vibrancy while addressing these concerns. The decision is expected to:

Maintain Liquidity: Weekly expiries drive significant trading volumes, ensuring that the market remains liquid and attractive to investors.
Reduce Volatility Spikes: By implementing eligibility criteria and other risk management measures, SEBI hopes to temper the extreme volatility seen on expiry days.
Support Broker Revenues: Stable trading volumes will help brokers maintain their income, which is critical for the ecosystem’s health.
Encourage Responsible Trading: The focus on investor eligibility and transparency will promote a more disciplined trading environment.

SEBI’s Broader Regulatory Framework

SEBI’s reversal on weekly expiries is part of a broader set of measures introduced since October 2024 to strengthen the derivatives market. These include:

Increased Contract Sizes: Raising the minimum contract value from ₹5-10 lakh to ₹15-20 lakh to deter speculative trading by small retail investors.
Upfront Premium Collection: Mandating brokers to collect option premiums upfront, effective February 1, 2025, to prevent excessive leverage.
Intraday Position Monitoring: Implementing checks at least four times a day starting April 1, 2025, to prevent large traders from manipulating the market.
Removal of Calendar Spread Benefits: Eliminating margin benefits for calendar spreads on expiry days to reduce speculative activity.
Standardized Expiry Days: Limiting weekly expiries to Tuesdays for NSE and Thursdays for BSE, effective September 1, 2025, to reduce volatility and align with global practices.

These measures have already shown some impact, with SEBI’s July 2025 study noting a 9% decline in index options turnover and a 20% drop in unique retail participants in FY25. However, retail participation remains high, and SEBI’s latest reversal ensures that the market remains accessible while continuing to evolve.

The Jane Street Controversy: A Catalyst for Change

The Jane Street case, where the US-based firm earned ₹44,358 crore from options trading but faced allegations of market manipulation, has been a significant driver of SEBI’s regulatory actions. The firm’s profits, primarily from high-frequency trading (HFT) in Bank Nifty options, highlighted vulnerabilities in India’s derivatives market. SEBI’s investigation into Jane Street underscored the risks of small options contracts and intraday price manipulation, prompting calls for stricter oversight.

Brokers’ suggestion to allow exchanges to reverse trades in extreme cases stems from this incident, aiming to prevent similar losses in the future. SEBI’s response—retaining weekly expiries while exploring risk mitigation frameworks—reflects a pragmatic approach to addressing these challenges without stifling market growth.

How Retail Investors Can Adapt to the New Landscape

For retail investors, SEBI’s reversal offers both opportunities and challenges. While weekly expiries provide continued access to short-term trading, the focus on eligibility criteria and risk management means traders must be more strategic. Here are actionable steps for retail investors to navigate this evolving market:

Educate Yourself: Understand the risks and mechanics of F&O trading. Resources like SEBI’s investor education portal and broker webinars can provide valuable insights.
Assess Your Eligibility: Prepare for potential criteria, such as minimum experience or capital requirements, to participate in F&O trading.
Diversify Your Portfolio: Instead of relying solely on derivatives, consider blue-chip stocks, mutual funds, or ETFs to balance risk.
Monitor Market Updates: Stay informed about SEBI’s circulars and broker announcements to adapt to regulatory changes.
Work with Reputable Brokers: Partner with brokers who comply with SEBI’s guidelines and offer robust risk management tools.

The Future of India’s Derivatives Market

SEBI’s reversal on weekly expiries signals a forward-thinking approach to regulating India’s derivatives market. By listening to brokers and prioritizing retail investor protection, the regulator is fostering a balanced ecosystem that supports growth while minimizing risks. The proposed eligibility criteria and risk management frameworks could set a global standard for derivatives trading, positioning India as a leader in financial innovation.

Looking ahead, the market is likely to see:

Increased Institutional Participation: Standardized expiry days and transparent frameworks may attract more foreign institutional investors, boosting market depth.
Technological Advancements: Brokers and exchanges will invest in systems to comply with intraday monitoring and risk management requirements.
Retail Investor Empowerment: Education and eligibility criteria will create a more informed and resilient retail trading community.
Global Alignment: SEBI’s measures align India’s market with global practices, enhancing its competitiveness in the international arena.

Conclusion: A Win-Win for the Market

SEBI’s decision to retain weekly index option expiries, announced on July 18, 2025, is a landmark move that balances investor protection with market vitality. By addressing brokers’ concerns and introducing risk management frameworks, SEBI ensures that retail investors can continue to participate in F&O trading without facing undue risks. This reversal not only preserves market liquidity but also sets the stage for a more transparent and stable derivatives market.

For retail investors, brokers, and the broader financial ecosystem, this development is a beacon of opportunity. By staying informed and adapting to SEBI’s evolving regulations, stakeholders can navigate this dynamic landscape with confidence. As India’s stock market continues to grow, SEBI’s proactive approach will play a crucial role in shaping its future, making it a win-win for all participants.
