SEBI tightens rules for trading equity derivatives: Here's what changed
SEBI is rolling out new rules for trading equity derivatives, kicking in from October 1, 2025.
This move comes after some big players, like US firm Jane Street, used strategies that ended up hurting regular investors.
Now, there's a stricter cap—entities can't take intraday net positions above ₹5,000 crore in index options.
New limits and checks for index options
The position limit has jumped up from ₹1,500 crore to ₹5,000 crore for index options, plus there's a new gross intraday exposure cap of ₹10,000 crore, applied separately to long and short positions.
To keep things fair, stock exchanges will run at least four random checks during the day (including one during the busiest trading window).
If anyone breaks these limits—especially on expiry days—they'll face penalties decided by the exchanges.
The goal: make trading safer and boost trust for everyone involved.
