Currency Futures - Definition
This sub‑topic explains what a Currency Future is, its essential characteristics, and why it is a cornerstone of the NISM Series I exam. Understanding the definition helps you differentiate futures from forwards and options, a frequent exam focus. The content fits into the broader module on Exchange Traded Currency Futures, laying the groundwork for later sections on pricing, margin and regulatory aspects.
Learning Objectives
- 1Define a Currency Future in the context of Indian exchanges.
- 2Identify the standard contract specifications for exchange‑traded currency futures.
- 3Explain how profit/loss is calculated using the mark‑to‑market method.
- 4Recognise common exam traps related to currency futures.
What is a Currency Future?
A Currency Future is a standardized, exchange‑traded contract that obligates the buyer to purchase, and the seller to deliver, a specified amount of foreign currency at a predetermined price on a future date.
Unlike over‑the‑counter (OTC) forwards, currency futures are cleared through a central clearing corporation, which eliminates counter‑party risk and ensures daily settlement of gains and losses.
For the NISM exam, the definition is tested by asking you to pick the statement that correctly captures the “standardised” and “exchange‑traded” nature of the instrument.
- Standardisation means contract size, tick size and expiry dates are fixed by the exchange.
- Exchange‑traded implies transparent price discovery through an order‑driven market.
Students often confuse futures with forwards. Remember: futures are exchange‑traded, centrally cleared and marked‑to‑market daily, whereas forwards are bilateral OTC contracts without daily settlement.
Key Features of Exchange Traded Currency Futures
Every currency future listed on NSE or BSE follows a set of uniform features: a fixed contract size (usually 1,000 units of the foreign currency), a tick size of 0.0001 (or the smallest price increment allowed by the exchange), and a set of quarterly expiry months (Mar, Jun, Sep, Dec).
Price quotation is expressed in the domestic currency per unit of foreign currency (e.g., INR per USD). The contract is settled either physically – by delivery of the underlying currency – or cash‑settled based on the final settlement price published by the exchange.
For the exam, you may be asked to identify which of these attributes is NOT a characteristic of an exchange‑traded currency future. Pay attention to the wording of each option.
Comparison of Core Features: Currency Futures vs. Currency Forwards
| Feature | Currency Futures | Currency Forwards |
|---|---|---|
| Trading Venue | National Stock Exchange (NSE) / BSE | OTC market |
| Contract Size | Standardised (e.g., 1,000 USD) | Negotiable |
| Clearing | Central Counterparty (CCP) | Bilateral |
| Settlement | Daily mark‑to‑market, final physical/cash settlement | Single settlement at maturity |
| Regulation | SEBI‑regulated, mandatory reporting | Less stringent, reporting optional |
Contract Specification
The contract specification sheet issued by the exchange lists all quantitative details. The most important items are:
- Lot Size – typically 1,000 units of the foreign currency (e.g., 1,000 USD).
- Tick Size – the minimum price movement, usually 0.0001 INR per USD.
- Price Quotation – expressed as INR per unit of foreign currency.
- Expiry Cycle – quarterly cycles (Mar, Jun, Sep, Dec) with a last trading day two business days before expiry.
Understanding these numbers is vital because many exam questions ask you to calculate the monetary value of a tick movement or the total notional exposure of a position.
Where:
C= Closing price of the futures contract (INR per unit of foreign currency)O= Opening price (price at which the position was entered) (INR per unit)S= Contract size – number of units of foreign currency per contract (e.g., 1,000)N= Number of contracts held (positive for long, negative for short)Worked Example
Given O = 82.50, C = 82.80, S = 1,000 USD, N = 2 contracts (long): Step 1: Difference = 82.80 - 82.50 = 0.30 INR per USD Step 2: Profit per contract = 0.30 × 1,000 = 300 INR Step 3: Total profit = 300 × 2 = 600 INR Verification: (82.80 - 82.50) × 1,000 × 2 = 600 INR.
A common mistake is to calculate profit/loss using only the price difference. Always multiply by the contract size and the number of contracts to get the monetary value.
Pricing and Valuation Basics
The theoretical price of a currency future is derived from the spot rate adjusted for the cost of carry, which includes the interest rate differential between the two currencies. The formula used in the syllabus is:
Future Price = Spot Rate × e^{(r_d - r_f) × T}, where r_d is the domestic interest rate, r_f is the foreign interest rate, and T is time to expiry in years.
In practice, Indian exchanges publish forward points that are added to or subtracted from the spot rate to obtain the futures price. Remember that forward points are quoted in paise (0.01 INR) for INR‑denominated contracts.

Margin and Mark‑to‑Market
When you open a futures position, you must deposit an Initial Margin (IM) as a performance bond. The exchange determines the IM as a percentage of the contract's notional value, typically ranging from 5% to 10% for major currency pairs.
Every trading day, the exchange calculates the variation margin (VM) by marking the position to market using the day’s settlement price. If the VM is positive, the amount is credited to your account; if negative, you must pay the shortfall, often triggering a margin call.
Exam questions frequently present a scenario with IM, daily price movement, and ask for the amount of additional cash required after a loss. Keep the MTM formula handy and remember that the margin requirement is recalculated each day.
Scenario
An investor buys 3 contracts of EUR/INR futures at an opening price of 88.50 INR per EUR. The contract size is 1,000 EUR. The exchange requires an initial margin of 8% of the notional value. After one day, the settlement price falls to 88.10 INR per EUR.
Solution
Step 1: Notional value = 88.50 × 1,000 × 3 = 265,500 INR. Step 2: Initial Margin = 8% × 265,500 = 21,240 INR (deposited upfront). Step 3: Daily price change = 88.10 - 88.50 = -0.40 INR per EUR. Step 4: MTM loss = (-0.40) × 1,000 × 3 = -1,200 INR. Step 5: Since the loss exceeds the available margin balance, a margin call of 1,200 INR is issued. The investor must transfer this amount to maintain the position.
Conclusion
The example shows how a small price move can erode the margin, emphasizing the importance of monitoring daily MTM and maintaining sufficient cash.
Regulatory Framework
SEBI (Securities and Exchange Board of India) regulates all exchange‑traded currency futures under the Securities Contracts (Regulation) Act, 1956. The key SEBI circulars mandate that brokers maintain a risk‑based margin system and that all positions be reported daily to the clearing corporation.
For NISM, remember the definition of a "Derivative" as per SEBI: a financial instrument whose value is derived from an underlying asset, such as a foreign exchange rate.
Failure to comply with SEBI’s margin and reporting requirements can lead to penalties, a point often tested in scenario‑based questions.
Do not apply OTC derivative rules (e.g., bilateral margin) to exchange‑traded currency futures. SEBI’s rules for futures are distinct and must be used.
Practical Use Cases
Indian exporters often use currency futures to lock in the INR value of future foreign receipts, thereby eliminating exchange‑rate risk. Conversely, speculators may take directional bets on INR appreciation or depreciation to earn returns from price movements.
Arbitrageurs exploit price differentials between the futures market and the spot market, using the cost‑of‑carry relationship to earn risk‑free profits. Understanding the definition and contract mechanics is essential to answer arbitrage‑related questions.
Exam writers love to frame a question around a corporate hedger who wants to protect a future USD inflow. The correct answer will reference the standardised contract size and daily MTM settlement.
Common Mistakes
1. Confusing tick value with tick size – tick size is the price increment; tick value is the monetary impact of one tick (tick size × contract size).
2. Ignoring the sign of the position – a short position reverses the MTM calculation sign.
3. Assuming physical delivery is mandatory – most currency futures on Indian exchanges are cash‑settled, and delivery occurs only if the holder chooses to take or make delivery.
4. Overlooking the expiry month cycle – forgetting that only specific months are listed can lead to wrong answers about contract availability.
⭐Exam Takeaways
- Currency Future = standardized, exchange‑traded contract to buy/sell a fixed amount of foreign currency at a predetermined price on a future date.
- Key specifications: lot size (usually 1,000 units), tick size (0.0001), quarterly expiry months, and daily mark‑to‑market settlement.
- Profit/Loss = (Closing price – Opening price) × Contract size × Number of contracts; always include contract size in calculations.
- Initial margin is a percentage (5‑10%) of the notional value; variation margin is settled daily and can trigger margin calls.
- SEBI governs currency futures; they are cleared through a central counterparty, eliminating counter‑party risk.
- Common exam traps: mixing futures with forwards, forgetting contract size, and mis‑applying OTC margin rules.
