SEBI Reconsiders Derivatives Trading Limits: Industry Voices Prompt a Rethink

In a welcome shift that could reshape how India's vast derivatives market operates, the Securities and Exchange Board of India (SEBI) is re-evaluating the framework governing trading limits—particularly around gross and intraday open interest. This reconsideration, while still in the discussion phase, comes after considerable pushback from large institutional players and industry bodies, most notably the Futures Industry Association (FIA).

For a regulator often known for its cautious approach, SEBI's willingness to listen and potentially course-correct reflects a broader, ongoing dialogue about how to balance trading flexibility with systemic risk control.

Why This Review Matters

At the heart of the debate is SEBI’s February 24, 2025 consultation paper titled “Enhancing Trading Convenience and Strengthening Risk Monitoring in Equity Derivatives.” Among other things, it proposed two important changes: better position-level disclosure and tighter oversight of derivatives-linked risk concentration.

But what really stirred the industry was a proposal to impose an intraday gross delta-based open interest (OI) limit of ₹2,500 crore on index derivatives. For hedge funds, proprietary desks, and high-volume institutions, that figure raised eyebrows.

The Pushback—and a Counterproposal

The FIA, which counts among its members major global funds like Jane Street and Citadel, responded quickly and emphatically. It asked for the end-of-day (EOD) net index future equivalent (FutEq) limit to be raised to ₹7,500 crore—a significant jump from current norms. Their argument? The existing limits are out of step with operational realities, especially for firms running high-frequency, market-making, or hedged positions across instruments.

They’re not alone. Several other market participants have suggested that even the intraday limits need to be doubled or tripled—placing the ideal range somewhere between ₹5,000 crore and ₹10,000 crore.

SEBI’s Emerging Stance: Flexibility on One Front, Caution on Another

SEBI hasn’t dismissed these views. Quite the opposite—the regulator has acknowledged the feedback and is actively considering a revision to the intraday gross limit. Insiders say there’s a high probability it could be raised, though by how much remains to be seen.

However, when it comes to the FIA’s ₹7,500 crore proposal for the EOD net limit, SEBI appears far less inclined. The regulator’s analysis suggests that very few participants actually operate at those levels. Raising the limit that high could, SEBI believes, amplify concentration risks and open the door to possible market manipulation.

The message is clear: flexibility will be granted where justified, but not at the expense of market stability.

The Technical Shift to Delta-Based OI: Why It Matters

Another major change in the works is SEBI’s plan to shift from a notional open interest calculation to a delta-based one. In plain terms, this means positions will be assessed based on their actual exposure to market movements—something traders refer to as their "delta."

This adjustment isn’t just academic. Delta-based calculations more accurately reflect real risk, especially for options and hedged portfolios. Globally, this is the standard approach—and India aligning itself with it is a significant move.

It also has practical implications: delta-based limits could reduce the number of times a stock enters a “ban” period due to technical breaches of position limits, a situation that frustrates traders and hampers liquidity.

Institutional View: Risk vs. Opportunity

For hedge funds and institutional investors, the implications are mixed. If intraday limits go up, as expected, it could unlock more trading room—allowing larger trades, tighter bid-ask spreads, and more efficient risk management. But those opportunities come with a catch: tighter surveillance and a higher standard of accountability.

Delta-based monitoring is far more precise, and SEBI’s enhanced systems will track both gross and net exposures. The margin for error—or exploitation—is shrinking.

What This Means for Market Health

Increased intraday limits could improve overall liquidity, especially in index derivatives, which form the bulk of volume on Indian exchanges. With fewer technical restrictions and more room to manoeuvre, large trades will face less friction.

But volatility is the flip side of flexibility. That’s why SEBI is pairing relaxed limits with upgraded surveillance tools and a more nuanced risk framework.

For retail investors, the impact may be less direct but still meaningful. With better transparency and controls in place, the risk of manipulation and sudden price swings diminishes—something SEBI has repeatedly emphasised as a regulatory priority.

A Divided but Engaged Industry

On balance, most industry voices have welcomed SEBI’s openness to review the intraday limits. The conservative approach to the EOD limit, while disappointing to some, has also been met with understanding. Most participants recognise the importance of not letting a few firms dominate or distort the market.

Here’s a quick look at how SEBI’s initial proposals compare to what the industry is asking for—and where things might land:

Limit Type	Initial SEBI Proposal	Industry Request	SEBI’s Likely Action
Intraday Gross Delta OI	₹2,500 crore	₹5,000–10,000 crore	Likely to be increased
EOD Net Index FutEq Limit	₹1,500 crore	₹7,500 crore (FIA)	Unlikely to be raised as proposed

Final Thoughts

What’s playing out now is a classic regulatory balancing act. On one side, a fast-evolving derivatives market driven by algorithmic strategies, international participation, and intense liquidity demands. On the other, SEBI’s mandate to protect market integrity and investor interests.

The fact that SEBI is engaging so directly with stakeholders—and appears willing to adjust parts of its proposal—is encouraging. But the message from the regulator is just as clear: more freedom will come with more oversight.
