Moneyness of an Option
Moneyness tells you whether a currency option is profitable if exercised today. It links the spot exchange rate with the option's strike price and determines the intrinsic part of the premium. In the NISM Series I exam, questions often test your ability to classify options as In‑the‑Money (ITM), At‑the‑Money (ATM) or Out‑of‑the‑Money (OTM) and to compute intrinsic value. Understanding moneyness also helps you explain why premiums differ across these categories. This sub‑topic sits in the Exchange Traded Currency Options chapter and is a high‑frequency exam focus.

- 4Identify common exam traps related to moneyness and avoid them.
Understanding Moneyness of a Currency Option
Moneyness is a snapshot measure that compares the current spot exchange rate (S) of a currency pair with the option's strike price (K). If the option were exercised right now, moneyness tells you whether the holder would make a profit (positive intrinsic value) or not (zero intrinsic value). The concept is identical for equity options, but in currency markets the spot is expressed in Indian rupees per foreign currency unit, making the comparison intuitive for Indian investors.
Why does moneyness matter for the exam? SEBI‑approved NISM study material repeatedly asks candidates to label an option as ITM, ATM or OTM given S and K, or to pick the correct intrinsic value from multiple‑choice options. The classification also determines the option's delta, which the exam may probe indirectly when discussing hedging effectiveness.
In practice, moneyness influences trading decisions. A trader may prefer ITM options for higher intrinsic value when seeking immediate exposure, while speculative traders often buy OTM options for lower premiums and higher leverage. The exam expects you to connect these practical implications with the theoretical definitions.
- Spot rate (S) – current market exchange rate of the underlying currency pair.
- Strike price (K) – price at which the option holder can buy (call) or sell (put) the currency.
Students often label an option as ITM when the spot equals the strike. Remember: when S = K the option is At‑the‑Money (ATM), not In‑the‑Money. Only a strict inequality (S > K for calls, S < K for puts) makes it ITM.
Classification of Options by Moneyness
Three categories exist: In‑the‑Money (ITM), At‑the‑Money (ATM) and Out‑of‑the‑Money (OTM). For a call option, ITM means the spot rate is higher than the strike (S > K); for a put, ITM means the spot is lower than the strike (S < K). ATM occurs when the spot and strike are equal (S = K) for both calls and puts. OTM is the opposite of ITM – the option would have zero intrinsic value if exercised today.
Each classification carries a typical range of option delta, which measures sensitivity of the option price to changes in the underlying spot. ITM options have deltas close to 1 (calls) or –1 (puts), ATM options have deltas around 0.5 (calls) or –0.5 (puts), and OTM options have deltas near 0. Understanding these ranges helps you answer delta‑related questions without complex calculations.
From an exam perspective, you may be given a table of spot and strike values and asked to mark the correct moneyness. Pay attention to the direction (call vs put) and remember that the sign of the inequality flips for puts.
Moneyness Classification for Currency Options
| Moneyness | Condition (Spot vs Strike) | Intrinsic Value | Typical Delta Range |
|---|---|---|---|
| In‑the‑Money (ITM) | Call: S > K; Put: S < K | Positive (|S‑K|) | Call ≈ 0.70‑1.00, Put ≈ –0.70‑–1.00 |
| At‑the‑Money (ATM) | S = K for both call and put | Zero (but premium > 0) | Call ≈ 0.45‑0.55, Put ≈ –0.45‑–0.55 |
| Out‑of‑the‑Money (OTM) | Call: S < K; Put: S > K | Zero | Call ≈ 0‑0.30, Put ≈ –0‑–0.30 |
Intrinsic and Extrinsic Value
The option premium consists of two parts. Intrinsic value is the immediate profit from exercising the option, calculated as the positive difference between spot and strike. Extrinsic value (also called time value) is the amount paid for the right to wait, reflecting volatility, time to expiry, and interest differentials. In currency options, extrinsic value can be sizable because of foreign exchange volatility.
Only ITM options possess intrinsic value; ATM and OTM options have zero intrinsic value, yet they still command a premium due to extrinsic value. The exam frequently asks you to separate these components, especially when given the total premium and asked to compute the intrinsic part.
Remember that intrinsic value cannot be negative – the max function in the formula ensures a floor of zero. This rule eliminates the possibility of a negative premium, a common source of confusion in practice questions.
Where:
S= Current spot exchange rate (INR per unit of foreign currency)K= Strike price of the call option (INR per unit)Worked Example
Given S = 75 INR/USD and K = 70 INR/USD: Step 1: Compute S - K = 75 - 70 = 5 Step 2: Apply max function: \max\{5, 0\} = 5 Verification: \max\{75 - 70, 0\} = 5 INR per USD.
Where:
K= Strike price of the put option (INR per unit)S= Current spot exchange rate (INR per unit)Worked Example
Given K = 68 INR/USD and S = 73 INR/USD: Step 1: Compute K - S = 68 - 73 = -5 Step 2: Apply max function: \max\{-5, 0\} = 0 Verification: \max\{68 - 73, 0\} = 0 INR per USD.
Moneyness and Option Premium
The total premium (P) of a currency option equals the sum of intrinsic value (IV) and extrinsic value (EV): P = IV + EV. As moneyness shifts from OTM to ITM, IV rises while EV typically falls because there is less optionality left. The exam may present a premium breakdown and ask which component is larger for a given moneyness.
For an ITM call, a large portion of the premium is intrinsic, so the option behaves more like a forward contract. Conversely, an OTM option’s premium is almost entirely extrinsic, making it sensitive to volatility and time decay. Understanding this relationship helps you answer scenario‑based questions on risk‑return trade‑offs.
Remember that SEBI’s definition of "premium" for exchange‑traded currency options includes transaction charges, but the core concept of intrinsic vs extrinsic remains unchanged. Exam questions focus on the theoretical split, not on brokerage fees.
Premium Composition by Moneyness (Illustrative)
NISM‑style Example: Determining Moneyness
Scenario
Rohit, a retail investor, looks at a USD/INR European call option with a strike of 74 INR per USD. The current spot rate is 78 INR per USD and the option expires in 30 days. The market premium quoted is 5.2 INR per USD. He wants to know whether the option is ITM, ATM or OTM and how much of the premium is intrinsic.
Solution
Step 1: Compare spot (S = 78) with strike (K = 74). Since S > K, the call is In‑the‑Money. Step 2: Compute intrinsic value using IV = max(S - K, 0) = max(78 - 74, 0) = 4 INR per USD. Step 3: Determine extrinsic value: EV = Premium - IV = 5.2 - 4 = 1.2 INR per USD. Step 4: Classify delta range – an ITM call typically has delta between 0.70 and 1.00; Rohit's option will likely have delta around 0.85, indicating high sensitivity to spot moves.
Conclusion
The option is ITM with an intrinsic value of 4 INR and an extrinsic (time) value of 1.2 INR. Knowing the breakdown helps answer multiple‑choice questions that ask for intrinsic value or the effect of moneyness on premium.
Students sometimes think an OTM option has zero premium because its intrinsic value is zero. The premium is never zero; the entire amount is extrinsic (time) value, which the exam may test.
⭐Exam Takeaways
- Moneyness compares spot (S) with strike (K) to label an option as ITM, ATM or OTM.
- Call ITM: S > K; Put ITM: S < K. ATM occurs when S = K for both.
- Intrinsic value formulas: Call IV = max(S‑K,0); Put IV = max(K‑S,0).
- Option premium = Intrinsic Value + Extrinsic (time) Value; OTM premium is purely extrinsic.
- Typical delta ranges: ITM ≈ 0.70‑1.00, ATM ≈ 0.45‑0.55, OTM ≈ 0‑0.30 (sign depends on call/put).
- Exam trap: Do not label S = K as ITM; also remember OTM options still have a non‑zero premium.
- When given S, K and premium, subtract intrinsic value to obtain extrinsic value – a frequent calculation question.
