In the Money (ITM)
An option that already has something to pay. It behaves more like the index and less like a bet, and on expiry day it is the one that settles.
In short: an option is in the money when exercising it now would produce a positive payoff: a call whose strike is below the underlying's price, or a put whose strike is above it. The size of that payoff is the option's intrinsic value, and the premium is that amount plus whatever time value remains. In-the-money options have deltas above 0.5 in magnitude, less time value than at-the-money options, and are the contracts that actually settle at expiry.
The intuition
A 23,500 call with Nifty at 24,000 lets you buy the index 500 points below where it trades. That 500 is money on the table, and no option can sell for less than it, because anyone could buy the option, settle it, and pocket the difference. So the premium of an in-the-money option starts from its intrinsic value and adds a smaller, shrinking slice of time value on top. The deeper in the money it goes, the smaller the slice, until a very deep option is almost pure intrinsic value and tracks the index nearly point for point.
Being in the money is a description, not a verdict. It says where the option stands against its strike today. Whether the position is profitable depends on what was paid for it, and whether it stays in the money depends on what the index does next.
Formula
Call is ITM if spot > strike; intrinsic value = spot − strike
Put is ITM if spot < strike; intrinsic value = strike − spot
Time value = premium − intrinsic value, which for ITM options is positive but smaller than at the money
Delta rises from about 0.5 at the money toward 1.0 (or −1.0 for puts) as the option moves deeper in.
Worked example (illustrative numbers)
Suppose NIFTY is at 24,000 with seven days to the Tuesday expiry and implied volatility at 14%. The in-the-money calls:
| Strike | Premium | Intrinsic | Time value | Delta | Cost per lot (65) |
|---|---|---|---|---|---|
| 23,900 | ₹257 | ₹100 | ₹157 | 0.61 | ₹16,705 |
| 23,700 | ₹394 | ₹300 | ₹94 | 0.77 | ₹25,610 |
| 23,500 | ₹558 | ₹500 | ₹58 | 0.88 | ₹36,270 |
| 23,000 | ₹1,031 | ₹1,000 | ₹31 | 0.99 | ₹67,015 |
Moving from 23,900 to 23,000 the premium quadruples, but the time value at risk shrinks from ₹157 to ₹31 and the delta approaches 1. A trader who wants index exposure for a week without the daily mark-to-market of a future can buy the 23,000 call: it costs ₹67,015, moves almost point for point with Nifty, decays only ₹31, and caps the loss at the premium if the index collapses. If Nifty settles at 24,300, each of these calls pays 300 more than it does today: the 23,000 call returns ₹1,300 per unit, a gain of ₹269 on ₹1,031, while the 23,900 call returns ₹400, a gain of ₹143 on ₹257. Same move, different leverage, different decay.
Why it matters to an options trader
- Directional exposure with less decay. ITM options carry little time value, so a directional view costs less in theta than an at-the-money option and keeps the premium cap on losses that a future lacks.
- Settlement is certain. At expiry, ITM contracts settle and OTM contracts vanish. Knowing which of your legs will be in the money at the close is the whole of expiry-day planning.
- Written ITM options are the writer's problem. A written option that has moved in the money is costing intrinsic value every point; the premium collected was the time value, and that is gone.
- Spreads are defined by moneyness. A bull call spread bought ITM/ATM behaves differently from one bought ATM/OTM: more cost, higher probability, less leverage.
Common mistakes
- Reading "in the money" as "in profit". It describes the strike, not the trade. Profit needs intrinsic value above the premium paid.
- Expecting an ITM premium to track the index exactly. Only deep ITM options do; a slightly ITM option still has meaningful time value and a delta well below 1.
- Letting a thin ITM option settle at expiry. STT on exercise is charged on intrinsic value; on a small amount it can exceed the gain, and closing in the market is often cheaper.
- Ignoring liquidity. Deep ITM strikes trade thinly; the bid-ask spread can erase the decay advantage.
- Holding ITM stock options into expiry unprepared. They settle by delivery: a long ITM stock call must pay for the shares, a long ITM put must deliver them.
Indian-market specifics
- All NSE and BSE options are European; an ITM option is exercised automatically at expiry and never before. Index options settle in cash at intrinsic value; stock options by physical delivery.
- Securities Transaction Tax from 1 April 2026: 0.15% of intrinsic value on exercise at expiry, against 0.15% of premium when sold in the market.
- Delivery margins are phased in on ITM stock options and futures over the last sessions before expiry.
- Lot sizes after the January 2026 revision: Nifty 65, Bank Nifty 30, FinNifty 60, Sensex 20; strike intervals Nifty 50, Bank Nifty 100, FinNifty 50, Sensex 100.
FAQ
When is a call in the money and when is a put?
A call when spot is above the strike; a put when spot is below it.
Why does an in-the-money option cost so much more?
Its premium includes intrinsic value that is already real; in return it has a higher delta and less time value to lose.
What happens to an in-the-money option at expiry on NSE?
Automatic exercise: cash settlement for index options, share delivery for stock options, with STT on the intrinsic value.
Does an ITM option always make money?
No; it must be in the money by more than the premium paid.
Which strikes are in the money right now
The option-chain pages shade in-the-money strikes and show each one's intrinsic value, premium and delta from the latest close. The options calculator splits any premium into intrinsic and time value.
