SEBI's Upcoming Deliberations on Index Options and Expiry Days Explained

What’s Next for Index Options? SEBI’s Crucial Meeting Could Redraw the Lines

If you trade in India’s fast-growing derivatives market, you’ll want to keep your radar tuned to SEBI this month. A high-stakes meeting of its secondary market advisory committee is on the horizon—and what comes out of it could reshape how index options and futures are traded in the country.

The Meeting That Could Shift the Ground Beneath Traders

On May 7, SEBI’s Secondary Market Advisory Committee (SMAC) is set to meet. But this isn’t a routine policy review. The committee—comprised of stock exchanges, brokers, industry associations, depositories, and government representatives—will take up two thorny but critical issues:

How much exposure is too much in index derivatives?
Should expiry dates be aligned across exchanges?

Why Index Options Limits Are Under the Scanner

Background: A Market That’s Outgrown Its Guardrails

Index trading in India has exploded. Since 2020, index levels and trading volumes have nearly tripled. But the open interest (OI) limits—which cap the notional value of derivative positions—haven’t kept pace.

At the core of the debate is whether today’s risk framework reflects the scale and sophistication of the market.

The Industry's Push

Big institutional investors, especially high-frequency traders (HFTs) and foreign institutional investors (FIIs), argue that current limits are too restrictive. They say intraday breaches are common even when their strategies are hedged, and the resulting penalties are arbitrary and unnecessary.

Some players have been pushing for gross intraday exposure limits of up to ₹15,000 crore.

SEBI’s Caution

But SEBI isn’t buying it—not without deeper scrutiny. The regulator is worried that netting of long and short positions might understate true risk.

Imagine a trader holding a ₹10,000 crore long position and an equally large short position. On paper, the net exposure is zero. But in a volatile market, those positions can unravel quickly, turning into real risk—especially when delta-adjusted exposures exceed ₹10,000 crore, as SEBI’s internal analysis found in some cases from November 2024.

What’s on the Table?

Here’s what SEBI is currently proposing to bring more granularity and control into how OI limits are applied:

For Index Options:

Limit Type	Proposed Value
Net Intraday	₹1,000 crore
Gross Intraday	₹2,500 crore
Net End-of-Day	₹500 crore
Gross End-of-Day	₹1,500 crore

For Index Futures:

Limit Type	Proposed Value
Intraday	₹2,500 crore (unchanged)
End-of-Day	₹1,500 crore (up from ₹500 crore)

This approach gives SEBI better visibility into both absolute risk (gross limits) and hedged positions (net limits). It's a shift towards risk-aware regulation, not one-size-fits-all policing.

The Other Issue: Standardising Expiry Days

Right now, different exchanges offer different expiry schedules for derivatives. This lack of alignment can:

Create confusion among investors
Lead to market fragmentation
Concentrate risk on certain days

SEBI is now weighing whether to standardize expiry days across exchanges. The idea is to simplify settlement, improve liquidity, and reduce operational risk.

It’s a quiet but important fix—one that could help level the playing field and make India's markets more aligned with global best practices.

What Happens Next?

Following the committee meeting, SEBI will likely review April’s OI data, incorporate stakeholder feedback, and then issue a final circular.

If adopted, the new OI framework and expiry standardization rules could come into effect later this year, changing how brokers, traders, and institutions manage their positions.

The Takeaway

This isn’t just another technical tweak. SEBI’s proposals reflect a maturing market—and a regulator trying to stay ahead of its own success.

For traders, brokers, and institutions, these decisions will shape everything from intraday strategies to risk compliance.
