Physical delivery timing on Zerodha

Overview

Physical delivery timing on Zerodha is the schedule on which margins ramp, obligations are computed, and shares and funds move when a stock futures or in-the-money stock option position is carried into expiry under compulsory physical settlement. The delivery margin steps up over the four trading days before expiry, the obligation is fixed after the close of the expiry session, and the actual transfer of shares and cash happens on the second trading day after expiry, Expiry plus 2 (NSE Clearing equity-derivatives settlement framework). Index derivatives are cash settled and carry none of this; only single-stock derivatives are physically settled, a rule in force since the physical settlement of stock F&O regime took effect in October 2019.

Timing is what makes physical settlement manageable or painful. A trader who knows the margin ramp begins four trading days out is not surprised by a block on free funds in expiry week. A trader who knows shares and funds settle on Expiry plus 2 can arrange the cash, or square off, before the obligation crystallises. The mechanics are an exchange framework that Zerodha passes through, not a Zerodha-specific schedule, so the same dates apply across brokers on the National Stock Exchange .

This article sets out the expiry-week delivery-margin ramp day by day, the expiry-day step-up on futures and short options, when the obligation is computed, the T+2 settlement of shares and funds, how delivered stock becomes tradeable, and how give and take delivery obligations net within the same scrip. It sits alongside the cost view in physical delivery risks in stock F&O and the levy detail in STT on options exercise .

What physical settlement covers

Single-stock futures and single-stock options on the National Stock Exchange are physically settled. A long in-the-money call carried into expiry becomes an obligation to take delivery of the underlying shares and pay full contract value. A short in-the-money call becomes an obligation to give delivery. A long in-the-money put becomes an obligation to give delivery, and a short in-the-money put an obligation to take delivery and pay. Stock futures held into expiry settle by delivery in the same way: the long takes shares, the short gives them.

Index derivatives, Nifty and Bank Nifty options and futures among them, are cash settled at the exchange final settlement price. No shares move, so the delivery timeline below does not apply to them. The whole of this article concerns stock derivatives.

The delivery margin ramp in expiry week

The exchange does not wait until expiry to collect the cash it will need to settle deliveries. It blocks a delivery margin on in-the-money long option positions in a staggered ramp over the four trading days before expiry, computed on the strike-price value of the position at the margin rate applicable to the underlying in the cash-market segment, that is the value-at-risk and extreme-loss margins of that security (NSE Clearing physical-settlement framework).

The block reduces free funds in Kite under a “Delivery Margin” line. It is an early-warning signal: when the block appears, the exchange has flagged the position as likely to settle by delivery. A trader who intends to square off rather than take delivery should treat the first appearance of the block, at Expiry minus 4, as the cue to act, because the ramp gets heavier each day and liquidity in stock options thins as expiry nears.

Expiry-day step-up on futures and short options

On expiry day the margin on stock futures and short option positions jumps. The requirement steps up to 50 per cent of contract value or 1.5 times the normal NRML margin, whichever is lower, on top of whatever the week’s ramp has already collected (NSE Clearing). This is why a futures position that sat on a few per cent of margin all month suddenly demands a large block on the last day. The detail on the SPAN and exposure components that feed the normal margin sits in SPAN margin on Zerodha and exposure margin on Zerodha .

When the obligation is computed

The delivery obligation is fixed after the close of trading on expiry day. The exchange computes it on all open futures positions and all in-the-money option contracts, taking the settlement price as the reference. For options, whether a contract is in the money is decided against the final settlement price of the underlying, so a position that was out of the money during the session can finish in the money and pull in an obligation, and the reverse.

This end-of-day computation is the moment the abstract risk of physical settlement becomes a concrete number of shares and a concrete cash figure. Nothing moves yet; the obligation is recorded, and the actual transfer follows on the settlement day.

The T+2 settlement of shares and funds

The shares and funds move on the second trading day after expiry, Expiry plus 2, through the depository pay-in and pay-out, the same settlement cycle a normal cash-market delivery follows.

For a take-delivery leg, a long futures position or a long in-the-money call, the shares are credited to the linked demat account on the T+2 buy-side settlement, and the trader must have the full contract value available for the pay-in. For a give-delivery leg, a short futures position or a short in-the-money call where the trader holds the stock, the shares are debited from demat on the same cycle. The pay-out completes the transfer.

The timeline strings together as follows: the obligation is fixed at the close of expiry day, the margin has been collected through the preceding four days, and on Expiry plus 2 the depository moves the shares one way and the cash the other. A trader taking delivery needs the contract value ready by that pay-in; a trader giving delivery needs the shares in demat, unpledged and available.

When delivered shares become tradeable

Shares delivered into demat through physical settlement can be sold from the trading day after they are credited, broadly Expiry plus 1 day for a clean settlement. Where the counterparty on the other side of the trade defaults and the shares reach the account only after a buy-in auction, the credit can slip to as late as T+2 days, and the sale window moves with it. The practical reading is that a trader who takes delivery to sell the stock the next morning can usually do so, but should not assume same-session liquidity on the delivered shares.

How give and take obligations net

Give and take delivery obligations in the same stock are netted at the client level. The exchange does not ask a trader holding offsetting positions to deliver and receive the same shares; it nets them to a single obligation. Equal lots of long futures, which take delivery, and short in-the-money calls on the same stock, which give delivery, cancel to a zero net delivery obligation.

The netting removes the cash and share movement, but it does not remove the margin. Delivery margins are charged on each F&O leg separately through expiry week even when the net obligation lands at zero, so a fully hedged position still ties up margin until it is closed or until settlement releases it. The release of the margin follows the completion of the settlement process, not the netting itself.

Acting on the timeline

The schedule gives a trader several clean decision points. The first appearance of the delivery margin block at Expiry minus 4 is the signal to decide whether to take delivery or exit. Squaring off before expiry removes the obligation, the margin block, and the heavier exercise levy detailed in STT on options exercise ; the operational steps are in how to avoid physical settlement of options . Rolling the position to the next expiry, set out in how to roll over an F&O position on Zerodha , keeps the exposure without delivery. A trader who genuinely wants the shares can let settlement run, provided the contract value is funded by the T+2 pay-in, the route described in how to physically settle an in-the-money option .
