Physical Settlement of Stock F&O in India: Full Guide
Every stock futures and stock options contract in India is physically settled, so any position open at expiry results in actual delivery of shares rather than a cash adjustment. Index contracts on Nifty, Bank Nifty and other indices stay cash settled, so delivery applies only to single stock contracts. Hold a stock F&O position into expiry and you will either pay full contract value and receive shares, or hand over shares and receive the money.
This is not a technicality. One lot of a Rs 1,500 stock can turn a Rs 6,000 option bet into a Rs 7.4 lakh cash requirement inside two days.
Below: what gets delivered in each position, how margins escalate through expiry week, a worked example with the securities transaction tax trap, and the checklist that avoids a surprise delivery.
Which contracts are physically settled
Stock futures and stock options on NSE settle by delivery. Index futures and index options settle in cash against the final settlement price.
All exchange traded options in India are European style, so a stock option can only be exercised on expiry day. That removes early assignment risk but concentrates every delivery obligation on one day.
Options finishing out of the money simply lapse. In the money options are exercised automatically by the exchange, with no form to fill and no way to decline.
Who delivers what: all six positions
| Position at expiry | Your obligation | Cash effect |
|---|---|---|
| Long stock futures | Take delivery | Pay full contract value |
| Short stock futures | Give delivery | Receive full contract value |
| Long call, in the money | Take delivery | Pay strike multiplied by lot size |
| Short call, in the money | Give delivery | Receive strike multiplied by lot size |
| Long put, in the money | Give delivery | Receive strike multiplied by lot size |
| Short put, in the money | Take delivery | Pay strike multiplied by lot size |
| Any option, out of the money | None, contract lapses | Premium already settled |
Two rows deserve a second look. A long put holder must deliver shares, buying them in the cash market if needed. A short put writer must buy at the strike, which is how a Rs 40 premium becomes a seven figure debit. If you write options, read assignment risk on short option positions before expiry week, not during it.
How margins escalate through expiry week
Because delivery needs full cash or full shares, the clearing corporation stops treating an expiry-week stock position as an ordinary derivative. It adds a delivery margin on top of SPAN and exposure margin, rising over the final sessions.
An illustrative pattern, where E is expiry day:
| Trading day | Illustrative delivery margin | What it means for you |
|---|---|---|
| E minus 4 | About 10% of delivery value | First top-up notice |
| E minus 3 | About 25% | Margin call if funds are short |
| E minus 2 | About 45% | Many brokers start force-squaring |
| E minus 1 | About 70% | Last practical day to exit cleanly |
| Expiry day | Full obligation | Delivery is locked in |
Treat those percentages as the shape, not as law: the exact steps are set by the clearing corporation and revised periodically, so check the current circular. The wider framework is in how options margin requirements work. Brokers add stricter house rules too, and many square off retail clients’ in the money short options unilaterally.
Worked example: the STT trap on one lot
Suppose a stock trades at Rs 1,500 and its lot size is 500 shares. Confirm the current lot size on the exchange contract specifications page, since these are revised periodically. Contract value is 500 multiplied by Rs 1,500, or Rs 7,50,000.
You buy the 1,480 call at a premium of Rs 12, costing 500 multiplied by Rs 12, or Rs 6,000.
The stock closes at Rs 1,505 on expiry day. The call is in the money by Rs 25, so intrinsic value is 500 multiplied by Rs 25, or Rs 12,500. Gross gain looks like Rs 6,500.
Route A, square off before the close. You sell the call at Rs 25. STT on selling an option is 0.15% of premium, so 0.15% of Rs 12,500 is Rs 18.75. Net gain is about Rs 6,481 before brokerage, and no shares move.
Route B, let it expire. The exchange exercises it. STT on an exercised or assigned option is 0.15% of settlement value, paid by the buyer. Settlement value is 500 multiplied by Rs 1,505, or Rs 7,52,500, so STT is Rs 1,128.75.
The same Rs 6,500 profit shrinks to roughly Rs 5,371 on tax alone, about 60 times the STT of Route A. You must also fund Rs 7,40,000, the strike multiplied by lot size, to take delivery, and selling those shares later costs another 0.1% STT.
That is the STT trap. Letting a small in the money option expire can cost far more than squaring off.
What happens if you cannot fund the delivery?
The obligation goes to the exchange settlement shortage process.
- The clearing corporation sources the missing shares through a close-out or auction, at a price far from the settlement price.
- The difference plus penalties is debited to you, with no predictable ceiling.
- Short delivery penalties apply per the exchange’s shortage policy.
- Your broker may liquidate other holdings to recover it.
- Repeat instances can get your F&O privileges restricted.
How do I avoid physical settlement?
Run this sequence every month on single stock positions.
- On the Monday of expiry week, list every stock F&O position with its lot size and contract value.
- Mark each option as in, at or near the money. Anything within roughly 2% of the strike can flip on the day: see in the money versus out of the money options.
- Decide in advance whether you want delivery. If yes, arrange the cash or shares now.
- If not, square off by E minus 1, and not in the final hour when stock option liquidity thins badly.
- To stay in the trade, roll to the next expiry instead of holding through.
- Keep spare cash through expiry week so a margin call does not force a bad exit.
Risk note: physical settlement makes stock options materially riskier than index options for beginners. One ignored position can create an obligation many times your account size. Trade index options while learning.
Frequently Asked Questions
Do I need a demat account with shares to write a covered call on a stock?
You need the shares by expiry, not on the day you write the call. Many brokers accept the shareholding as margin if you pledge it, which reduces the cash you must keep. If the call finishes in the money and you do not hold the shares, you face short delivery and auction penalties.
Are Nifty and Bank Nifty options physically settled?
No. All index derivatives in India are cash settled against the final settlement price on expiry day, so no shares move and no delivery margin applies. That is one reason index options carry far more open interest among retail traders than single stock options do.
What if my long option is only slightly in the money at expiry?
It still gets exercised automatically, and the 0.15% exercise STT is charged on the settlement value, not on your small intrinsic gain. That combination frequently turns a marginal winner into a net loss. Squaring off, even at a poor price, is usually the cheaper choice for a barely in the money position.
How is the profit from physically settled stock F&O taxed?
F&O income is treated as non-speculative business income and reported in ITR-3. It can be set off against other business income, and losses carry forward for eight years if you file the return by the due date. Once shares are delivered into your demat account, any later gain on selling them is a separate capital gain.
Can my broker stop me from taking physical delivery?
Yes. Brokers set risk policies stricter than the exchange minimum and many square off in the money stock option positions from two days before expiry, especially short options. This is disclosed in their policy document. Check it before expiry week so a forced exit does not surprise you.
Key Takeaways
- Stock futures and options settle by delivery, index derivatives settle in cash, and there is no way to opt out.
- Long calls and short puts take delivery and pay strike multiplied by lot size; short calls and long puts give delivery and receive it.
- Delivery margin escalates over the last four sessions until it reaches the full obligation, so confirm current percentages with the clearing corporation.
- Exercise STT of 0.15% applies to settlement value, while selling the option charges 0.15% of premium only: a difference of 50 times or more.
- Square off or roll by E minus 1 unless you have arranged the full cash or the shares.
- Failing to deliver triggers auction, close-out pricing and uncapped penalties, so never carry a forgotten stock position into expiry.
