Physical Settlement of Stock F&O — What to Know
Stock derivatives now settle by physical delivery at expiry. If you forget to close a position, you could owe the shares. Here’s how it works.

Since SEBI mandated it, stock (not index) futures and options are physically settled at expiry — meaning open positions result in actual delivery of shares, not just a cash difference. This catches many traders off guard.
What physical settlement means
If you hold a stock F&O position until expiry, instead of settling the profit/loss in cash, you must give or take delivery of the underlying shares:
- Long futures / exercised long call → you must buy (take delivery of) the shares and pay the full value.
- Short futures / assigned short option → you must deliver the shares (or buy them to deliver).
This requires the full contract value in funds or the actual shares — far more than the margin you posted.
Why it matters
- Don’t let positions expire by accident. A small option position left open can create a large, unexpected delivery obligation and hefty margin requirements in the expiry week.
- Brokers raise margins sharply in the days before expiry for positions likely to go to delivery, and may square off positions you can’t fund.
- In-the-money options are the common trap — a cheap ITM option expiring can obligate you to a large delivery.
The safe habit
Unless you specifically intend to take/give delivery and have the funds/shares, close or roll stock F&O positions before expiry. Index F&O remains cash-settled, so this applies only to stock derivatives. Derivatives are high-risk. Education only, not advice.
