SEBI’s F&O crackdown: what changed in 2024–25, and why

In late 2024, SEBI rolled out its biggest shake-up of futures and options trading in years. The trigger was blunt: its own studies showed that roughly 9 in 10 individual F&O traders lose money, with collective losses running into tens of thousands of crores. Here's what changed, and why it matters. This is for learning only.

Why SEBI stepped in

Weekly index options had turned into a vast, cheap lottery — tiny premiums, huge turnover, expiry-day gambling, and consistent losses for retail traders. The reforms aim to make derivatives a little less accessible as a casino and a little more like the hedging tool they're meant to be. (See who actually makes the money in F&O.)

The six measures

• Bigger contracts. The minimum contract value was raised from ₹5 lakh to the ₹15–20 lakh range — the first revision in nine years. Lot sizes went up accordingly, so a single trade now needs far more capital. (From November 2024.)
• Fewer weekly expiries. Each exchange may offer weekly expiry on only one benchmark index — NSE on Nifty or Bank Nifty, not both. This cut the number of high-risk expiry days. (From 20 November 2024.)
• Full premium upfront. Option buyers must pay the entire premium up front, ending the intraday leverage brokers allowed on premiums. (From 1 February 2025.)
• Extra margin on expiry day. A 2% additional "extreme loss margin" on short index options on expiry day, when moves are wildest.
• Calendar-spread benefit removed on expiry day, so positions expiring that day no longer get offsetting margin relief.
• Intraday position monitoring. Exchanges now check position limits several times during the day, not just at close. (From 1 April 2025.)

What it means for a retail trader

Trading options now needs more capital and offers fewer expiry-day lottery tickets. None of it changes the core maths: derivatives are a zero-sum game before costs, and most individuals lose. The rules make reckless F&O harder — they don't make it profitable.
