Contract Value
This sub‑topic explains the concept of Contract Value for Exchange Traded Currency Futures. Understanding how to compute the value of a futures contract is essential for pricing, margin calculation and risk management. The exam frequently tests the formula, its components and the impact of price movements on contract value. Mastery of this topic enables candidates to answer quantitative and scenario‑based questions confidently.

- 4Recognise common exam traps related to contract size and multiplier.
Understanding Contract Value
Contract Value is the monetary worth of a single futures contract expressed in the quoted currency (for example INR when dealing with USD/INR futures). It is calculated by multiplying the prevailing futures price by the contract size, which is the quantity of the base currency stipulated by the exchange.
The contract size for most Indian currency futures is fixed at 1,000,000 units of the base currency. For instance, a USD/INR futures contract represents one million US dollars. The futures price is quoted as INR per USD, so the contract value will be in INR.
Why this matters for the exam: the contract value is the basis for determining the initial margin, exposure, and the mark‑to‑market cash flows. Questions often ask you to compute the value, compare it across contracts, or infer the margin requirement from a given value.
- Spot price vs futures price – the contract value uses the futures price, not the spot price.
- Currency pair notation – the first currency is the base (quantity), the second is the quote (price unit).
Students sometimes substitute the spot exchange rate into the contract‑value formula. Remember: the contract value always uses the quoted futures price, not the spot rate.
Formula for Contract Value
Where:
F= Futures price in quoted currency per unit of base currency (e.g., INR per USD)S= Contract size – number of units of the base currency (e.g., 1,000,000 USD)Worked Example
Given F = 82.50 INR/USD and S = 1,000,000 USD: Step 1: CV = 82.50 \times 1,000,000 Step 2: CV = 82,500,000 INR Verification: 82.50 \times 1,000,000 = 82,500,000 INR.
The formula is deliberately simple because the exchange standardises the contract size. No additional multiplier is required for Indian currency futures; the size itself acts as the multiplier.
Units matter: if the futures price is quoted in INR per USD, the resulting contract value will be in INR. If a different pair such as EUR/INR is considered, the price will be INR per EUR and the contract value will still be in INR.
Exam relevance: the NISM question bank often presents a futures price and asks for the contract value. You must multiply correctly and retain the appropriate number of decimal places as shown in the contract specifications.
Calculating Contract Value – Worked Example
Scenario
Rohit, a distributor, wants to sell one USD/INR futures contract when the futures price is 81.20 INR per USD. The exchange defines the contract size as 1,000,000 USD. He needs to know the contract value to assess the margin requirement.
Solution
Step 1: Identify the futures price (F) = 81.20 INR/USD. Step 2: Identify the contract size (S) = 1,000,000 USD. Step 3: Apply the formula CV = F × S. CV = 81.20 × 1,000,000 = 81,200,000 INR. Step 4: If the exchange mandates an initial margin of 5% of contract value, the margin = 0.05 × 81,200,000 = 4,060,000 INR.
Conclusion
Rohit’s contract value is 81.2 million INR, and the required initial margin is 4.06 million INR. This calculation mirrors typical NISM exam items where you must compute both contract value and margin.
Impact of Futures Price Movements on Contract Value
Because contract value is a direct product of futures price and contract size, any change in the futures price leads to a proportional change in contract value. A 1% rise in the futures price raises the contract value by exactly 1%.
This linear relationship simplifies mark‑to‑market calculations. At the end of each trading day, the exchange settles the difference between the previous day's futures price and the current price, multiplied by the contract size. The resulting cash flow is the daily profit or loss.
For the exam, remember that the percentage change in contract value equals the percentage change in futures price, provided the contract size remains constant. Questions may ask you to compute the new contract value after a price move or to infer the daily settlement amount.
Contract Value at Different Futures Prices (USD/INR)
Comparison of Contract Sizes Across Currency Pairs
Standard contract sizes for major Indian currency futures (as per NSE/MCX specifications)
| Currency Pair | Contract Size (Base Currency) | Quote Currency |
|---|---|---|
| USD/INR | 1,000,000 | INR |
| EUR/INR | 1,000,000 | INR |
| JPY/INR | 100,000,000 | INR |
Some candidates multiply the futures price by the contract size and then again by a ‘multiplier’. For Indian currency futures the contract size itself is the multiplier; an extra factor leads to an inflated contract value.
Margin and Mark‑to‑Market Implications
The initial margin is typically expressed as a percentage of the contract value. Since contract value is directly derived from the futures price, any rise in price increases the margin requirement proportionally.
Mark‑to‑market (MTM) settlement uses the change in futures price multiplied by the contract size. For example, if the price moves from 81.00 to 81.50 INR/USD, the daily MTM amount = (81.50‑81.00) × 1,000,000 = 500,000 INR. This amount is credited or debited to the trader’s account at the end of the day.
Exam tip: when a question provides the previous and current futures price, compute the price difference, multiply by the contract size, and then apply any margin percentage if asked. Do not forget to keep the sign (profit vs loss) as it determines whether cash is received or paid.
⭐Exam Takeaways
- Contract Value = Futures Price × Contract Size; the size itself acts as the multiplier for Indian currency futures.
- Use the futures price (quoted currency per unit of base currency), not the spot rate, when calculating contract value.
- A 1% change in futures price results in a 1% change in contract value because the relationship is linear.
- Initial margin is a fixed percentage of contract value; therefore, margin changes proportionally with price movements.
- Mark‑to‑market settlement = (Current Futures Price – Previous Futures Price) × Contract Size.
- Standard contract sizes: USD/INR and EUR/INR – 1,000,000 units; JPY/INR – 100,000,000 units.
- Avoid adding an extra multiplier; the contract size already incorporates it.
- Remember to retain units (INR) throughout calculations to prevent answer‑key mismatches.
