Key Takeaways

  • Index Options — Nifty, Bank Nifty, Sensex are always cash settled (no shares change hands)
  • Stock Options — Physical delivery mandatory (you must give or take actual shares)
  • In-The-Money (ITM) — Options with value are automatically exercised on expiry
  • Out-of-The-Money (OTM) — Options with no value expire worthless, no action needed
  • Margin Matters — Stock options need extra margin for physical delivery from expiry week

The Expiry Day Confusion Most Traders Face

It's Thursday, 3:25 PM. Your Bank Nifty call option is ₹200 in profit. You're excited. Then suddenly, you panic:

"Wait... what happens now? Will I get shares? Will someone take my money? Do I need to do something?"

If this sounds familiar, you're not alone. Option settlement confuses most Indian traders — even those who've been trading for years.

The good news? It's actually simpler than you think. In the next 15 minutes, you'll understand exactly what happens to your options when they expire.

"Understanding settlement is like understanding the rules of a game. You can't win if you don't know how points are scored."

— Trading Wisdom

Let's clear the confusion once and for all.

01

What is Option Settlement? The Simple Version

Think of option settlement like closing a deal.

When you buy an option, you're making a deal with someone. On expiry day, that deal must be closed. Settlement is simply how that deal gets closed.

The Deal

Option buyer has the RIGHT to buy/sell something at a fixed price

Expiry Day

The last day when this deal is valid

Settlement

How money or shares change hands to close the deal

The Restaurant Booking Analogy

Imagine you book a table at a fancy restaurant for Saturday night. You pay ₹500 as booking fee.

  • If you show up: You get the table. Your booking fee was worth it.
  • If you don't show up: You lose your ₹500 booking fee. The restaurant keeps it.

Options work the same way. The premium you pay is like the booking fee. On expiry, the deal is either executed or it expires worthless.

But here's where it gets interesting: In India, different options are settled in different ways.

02

Two Types of Settlement in India

In India, SEBI (the market regulator) allows two types of settlement:

Feature Cash Settlement Physical Delivery
What happens Only money changes hands Actual shares change hands
Used for Index options (Nifty, Bank Nifty, Sensex) Stock options (Reliance, TCS, HDFC, etc.)
Do you need shares? No, just money in your account Yes, you need shares or money to buy shares
Complexity Simple and easy More complex, needs planning

Let's understand each type in detail.

03

Cash Settlement: The Simple One (Index Options)

Cash settlement is like betting on a cricket match. You don't get the trophy — you just get money if you win.

How It Works

When your index option (Nifty, Bank Nifty, Sensex) expires In-The-Money (ITM):

Simple Formula

You receive: (Settlement Price - Strike Price) × Lot Size

Real Example — Bank Nifty Call Option

Let's say you bought:

  • Bank Nifty 48000 CE (Call Option)
  • Premium paid: ₹150
  • Lot size: 15

On expiry day: Bank Nifty closes at 48500.

Your option is In-The-Money by 500 points (48500 - 48000 = 500).

You Paid

₹150 × 15 = ₹2,250

Your Profit

₹7,500 - ₹2,250 = ₹5,250

Notice: No shares were bought or sold. Only money changed hands. This is cash settlement.

What Happens to OTM Options?

If Bank Nifty closed at 47800 instead (below your 48000 strike):

  • Your option is Out-of-The-Money (OTM)
  • It expires worthless
  • You lose your premium (₹2,250)
  • No action needed — it just disappears from your account

Good to Know

Cash settlement happens automatically. You don't need to click any button or do anything. The exchange calculates everything and credits or debits your account by T+1 day.

04

Physical Delivery: The Tricky One (Stock Options)

This is where most traders get surprised. Since 2019, SEBI made physical delivery mandatory for all stock options.

What does this mean? If your stock option expires ITM, actual shares will be delivered.

The Marriage Analogy

Think of stock options like an arranged marriage:

  • Call option: You promised to "marry" (buy) the shares at a fixed price
  • Put option: Someone promised to "marry" (buy) the shares from you at a fixed price

On expiry, if the option is ITM, this "marriage" must happen — shares must change hands!

Real Example — Reliance Call Option

You bought:

  • Reliance 2800 CE (Call Option)
  • Lot size: 250 shares
  • Premium paid: ₹30 per share (₹7,500 total)

On expiry: Reliance closes at ₹2,900.

Your option is ITM. Now here's what happens:

You Must Pay

₹2,800 × 250 = ₹7,00,000

You Will Receive

250 shares of Reliance in your Demat account

Your profit is ₹25,000 (minus the ₹7,500 premium = ₹17,500 net profit). But the important thing is: You now own 250 Reliance shares!

Critical Warning

If you don't have ₹7 lakh in your account to buy those shares, you're in trouble! This is why physical delivery needs careful planning. More on this in the next section.

What About Put Options?

If you had bought a Reliance 2900 PE (Put Option) and Reliance closed at ₹2,800:

  • Your put is ITM
  • You must deliver 250 shares of Reliance
  • You will receive ₹2,900 × 250 = ₹7,25,000

The catch: You must own those 250 shares to deliver. If you don't have them, your broker will buy them from the market — often at a loss to you.

05

Physical Delivery Rules You Must Know

Physical delivery has some important rules. Breaking them can be expensive.

Rule 1: Margin Increases During Expiry Week

From 4 days before expiry, margins on stock options increase. This is because the exchange wants to make sure you can afford the delivery.

Day Margin Requirement
Normal Days Standard F&O margin
E-4 (4 days before expiry) 10% of contract value added
E-3 25% of contract value added
E-2 45% of contract value added
E-1 (day before expiry) 70% of contract value added

This can catch you off guard. A position that needed ₹50,000 margin might suddenly need ₹3-4 lakh during expiry week!

Rule 2: Close Before Expiry to Avoid Delivery

Don't want physical delivery? Simple solution: Close your position before expiry.

  • Sell your calls before 3:30 PM on expiry day
  • Buy back your puts before 3:30 PM on expiry day
  • You'll get your profit/loss in cash, no shares involved

Pro Tip

Most traders close their stock options 1-2 days before expiry to avoid margin increases and delivery complications.

Rule 3: What If You Can't Afford Delivery?

If you hold an ITM stock option till expiry but don't have money/shares for delivery:

  • Your broker will try to square off your position at market price
  • You might face penalties and auction charges
  • The closing price might be worse than expected
  • Some brokers charge additional fees for forced closure

Horror Story

A trader once held 5 lots of Bajaj Finance calls (625 shares) thinking he'd just get cash profit. On expiry, his broker demanded ₹45 lakh for delivery. He didn't have it. The forced closure cost him his entire profit plus extra fees. Don't be that trader.

06

Understanding ITM, ATM, and OTM at Expiry

Whether your option settles or expires worthless depends on one thing: Is it In-The-Money?

For Call Options (CE)

In-The-Money (ITM)

Current price > Strike price
Example: Nifty at 22500, your 22000 CE is ITM

At-The-Money (ATM)

Current price ≈ Strike price
Example: Nifty at 22000, your 22000 CE is ATM

Out-of-The-Money (OTM)

Current price < Strike price
Example: Nifty at 22000, your 22500 CE is OTM

For Put Options (PE)

In-The-Money (ITM)

Current price < Strike price
Example: Nifty at 22000, your 22500 PE is ITM

At-The-Money (ATM)

Current price ≈ Strike price
Example: Nifty at 22500, your 22500 PE is ATM

Out-of-The-Money (OTM)

Current price > Strike price
Example: Nifty at 22500, your 22000 PE is OTM

"Only ITM options have settlement value. OTM options expire worthless. There's no in-between on expiry day."

Expiry Days in India: The Complete Schedule

India has one of the busiest expiry schedules in the world. Here's when different options expire:

Index/Stock Expiry Day Settlement Type
Bank Nifty Weekly Wednesday Cash
Nifty Weekly Thursday Cash
Sensex Weekly Friday Cash
FinNifty Weekly Tuesday Cash
Midcap Nifty Weekly Monday Cash
Monthly Options (All) Last Thursday of month Cash (Index) / Physical (Stock)

Holiday Adjustment

If expiry day is a market holiday, expiry moves to the previous trading day. Always check the NSE holiday calendar!

08

Settlement Timeline: When Do You Get Your Money?

After expiry, here's what happens:

Cash Settlement Timeline

  • Expiry Day (T): Market closes at 3:30 PM, settlement price calculated
  • T+1 Day: Money credited or debited to your trading account

Example: If Nifty expires on Thursday, you'll see the settlement amount in your account by Friday evening.

Physical Delivery Timeline

  • Expiry Day (T): Position marked for delivery
  • T+1 Day: Shares debited/credited to your Demat account
  • T+1 Day: Money debited/credited to your trading account

Settlement Timing

India moved to T+1 settlement in 2024, making it one of the fastest settlement markets in the world!

09

What About Option Sellers?

Everything we discussed applies to option buyers. But what if you sold options?

If You Sold a Call Option (CE)

You have the obligation to deliver shares if the buyer wants them.

  • Index options: You pay the settlement difference if ITM
  • Stock options: You must deliver the shares if ITM

Example: You sold Tata Motors 800 CE. Stock closes at 850. You must deliver shares at ₹800 (or buy them at ₹850 and deliver at ₹800, losing ₹50 per share).

If You Sold a Put Option (PE)

You have the obligation to buy shares if the buyer wants to sell them.

  • Index options: You pay the settlement difference if ITM
  • Stock options: You must accept delivery of shares if ITM

Example: You sold Infosys 1500 PE. Stock closes at 1400. You must buy 400 shares at ₹1500 each (₹6 lakh), even though they're worth only ₹5.6 lakh in the market.

Seller's Risk

Option sellers have unlimited risk (for calls) or substantial risk (for puts). Physical delivery makes this even more dangerous. Always know your maximum obligation before selling stock options.

5 Common Settlement Mistakes to Avoid

Ignoring Physical Delivery

Many traders hold stock options till expiry without realizing they'll need lakhs for delivery

Forgetting Margin Increase

Not keeping extra margin during expiry week leads to forced closure at bad prices

Confusing Settlement Price

Settlement price isn't always the last traded price. It's a calculated average that can differ

Not Checking STT

ITM options at expiry attract higher STT (0.125% vs 0.0625% on premium). This can eat profits

Waiting Till Last Minute

Trying to close positions in the last 5 minutes often leads to slippage and worse fills

11

The STT Trap on Expiry Day

Here's something that surprises most traders: STT (Securities Transaction Tax) is higher on ITM options at expiry.

Scenario STT Rate Charged On
Selling option before expiry 0.0625% Premium amount
ITM option at expiry (exercised) 0.125% Full contract value (strike × lot size)

Example of STT Impact

You hold Nifty 22000 CE. Nifty expires at 22100.

Option 1: Sell before expiry at ₹105

  • Premium: ₹105 × 75 = ₹7,875
  • STT: 0.0625% of ₹7,875 = ₹4.92

Option 2: Let it expire ITM

  • Contract value: ₹22,000 × 75 = ₹16,50,000
  • STT: 0.125% of ₹16,50,000 = ₹2,062.50

That's a ₹2,057 difference in taxes! For a ₹7,500 profit, losing ₹2,000+ to STT is painful.

Smart Move

If your ITM option has only small intrinsic value, it's often cheaper to sell before expiry than let it expire and pay higher STT.

12

Practical Tips for Expiry Day Trading

Trade Early

Close positions by 3:00 PM. Last 30 minutes can be chaotic with wild swings and poor liquidity

Calculate STT

For deep ITM options, calculate if selling early saves you money on STT

Keep Extra Margin

During expiry week, maintain 20-30% extra margin for stock options

Avoid Illiquid Strikes

Deep ITM or OTM options can be hard to sell at fair prices on expiry

"Expiry day is not for gambling. It's for executing your plan. If you don't have a plan, you don't have a trade."

Frequently Asked Questions

Best trading windows: 9:30-10:30 AM (after opening volatility settles, trend emerges) and 2:00-3:15 PM (clear trend, less noise). Avoid first 15 minutes (gap volatility) and 12-1 PM (low volume). On expiry days, 2-3 PM often sees the biggest moves.

Option buying: Premium cost only (₹5,000-50,000 per lot). Option selling: SPAN + Exposure margin = ₹1-1.5 lakh per lot. Recommended minimum capital: ₹2-5 lakhs to trade safely with proper position sizing. Never trade with money you can't afford to lose.

Bank Nifty consists only of banking stocks which are highly sensitive to: RBI policy changes, interest rate decisions, credit growth data, and global banking news. It has higher FII participation and narrower breadth (12 stocks vs Nifty's 50), making it move faster and further.

On expiry day: theta decay is maximum (options lose value rapidly), gamma risk is highest (small moves cause big premium changes), ITM options settle at intrinsic value, OTM options expire worthless. Many traders avoid expiry day due to unpredictable moves. Wednesday is Bank Nifty weekly expiry.
