Overview of Commodity and Currency Derivatives
Commodity derivatives are contracts whose underlying asset is a physical commodity such as crude oil, gold, agricultural produce, or metals. They enable market participants to lock in future prices, thereby managing price volatility that can affect production costs or revenue streams.
Currency derivatives have a foreign exchange rate as the underlying. They are used to hedge exposure to exchange‑rate movements, to speculate on currency movements, or to arbitrage between markets. In India, the most common currency derivatives are USD/INR, EUR/INR, and GBP/INR contracts.
Both commodity and currency derivatives are traded on recognized exchanges (e.g., MCX for commodities and NSE/BSE for currency contracts) and are regulated by SEBI. The exam often asks you to differentiate the two based on underlying asset, market participants, and typical usage.
- Underlying asset – physical commodity vs foreign exchange rate.
- Primary users – producers, traders, exporters/importers vs corporates, investors, and speculators.
Students sometimes label a currency forward as a ‘currency future’. Remember: forwards are OTC contracts, while futures are exchange‑traded. SEBI governs futures and options; RBI oversees forwards.
Commodity Derivatives – Types
The two most common commodity derivative contracts are futures and options. A commodity future obligates the holder to buy or sell a specified quantity of the commodity at a predetermined price on a future date. Settlement can be physical (delivery of the commodity) or cash‑settled, depending on the contract specifications.
A commodity option gives the holder the right, but not the obligation, to buy (call) or sell (put) the underlying commodity at a strike price before or at expiry. Options provide asymmetric risk: the premium paid is the maximum loss for the buyer, while the seller faces unlimited risk for calls.
Swaps and forward contracts also exist in the commodity space, mainly for corporate hedgers. However, the NISM syllabus focuses on futures and options, and exam questions typically revolve around their payoff diagrams, margin requirements, and settlement mechanisms.
- Futures – linear payoff, mandatory settlement.
- Options – non‑linear payoff, premium paid upfront.
Key Differences Between Commodity Futures and Commodity Options
| Feature | Commodity Futures | Commodity Options |
|---|---|---|
| Obligation | Buyer and seller must transact at expiry | Buyer has right, not obligation; seller is obligated if exercised |
| Pay‑off Profile | Linear (gain/loss mirrors price movement) | Non‑linear; limited loss for buyer (premium) |
| Margin Requirement | Initial and variation margin daily | Margin only for seller (option writer) |
| Risk for Buyer | Unlimited both ways | Limited to premium paid |
Currency Derivatives – Types
Indian currency derivatives include currency futures, currency options, currency forwards, and currency swaps. Futures and options are exchange‑traded and fall under SEBI's jurisdiction, while forwards and swaps are OTC instruments regulated primarily by the RBI.
A currency future contracts for a standard lot (e.g., USD 1,000) and settles in cash based on the closing INR/USD rate on the expiry date. Currency options work similarly to commodity options, providing the right to buy (call) or sell (put) a currency at a predetermined strike rate.
These instruments are crucial for Indian exporters, importers, and portfolio managers who need to hedge foreign‑exchange risk. The exam often tests the distinction between hedging (risk reduction) and speculation (risk taking) motives.
- Futures – standardized, exchange‑traded, daily MTM.
- Options – right without obligation, premium paid.

Regulatory Framework – SEBI and RBI
SEBI (Securities and Exchange Board of India) regulates all exchange‑traded derivatives, including commodity and currency futures and options. Participants must obtain a SEBI‑registered broker, maintain a margin account, and comply with position limits and reporting norms.
RBI (Reserve Bank of India) oversees OTC currency contracts such as forwards and swaps. RBI mandates that only authorized entities (banks, NBFCs, and certain corporate participants) can enter into these contracts, and they must be reported to the RBI’s Foreign Exchange Management System (FEMS).
For the NISM exam, remember the split: SEBI → exchange‑traded; RBI → OTC. Questions may ask which regulator prescribes the margin requirement for a currency future (answer: SEBI).
- SEBI: registration, margin, position limits.
- RBI: OTC approvals, reporting to FEMS.
Do not assume SEBI regulates all foreign‑exchange contracts. Only exchange‑traded currency futures and options are under SEBI; forwards and swaps are RBI’s domain.
Pricing Basics – Cost‑of‑Carry Model for Futures
Where:
F= Theoretical futures price in rupeesS= Current spot price of the commodity in rupeesr= Risk‑free interest rate (annual) expressed as decimalu= Storage cost rate (annual) expressed as decimaly= Convenience yield rate (annual) expressed as decimalT= Time to expiry in yearsWorked Example
Given S = 2000 ₹/barrel, r = 5% (0.05), u = 2% (0.02), y = 1% (0.01), T = 0.5 years: Step 1: Compute (r+u‑y) = 0.05+0.02‑0.01 = 0.06 Step 2: Multiply by T: 0.06 × 0.5 = 0.03 Step 3: Exponential factor e^{0.03} ≈ 1.030454 Step 4: Futures price F = 2000 × 1.030454 ≈ 2060.91 ₹ Verification: 2000 × e^{(0.05+0.02‑0.01)×0.5} = 2060.91 ₹.
The cost‑of‑carry model links the futures price to the spot price by accounting for the financing cost (r), storage cost (u), and the convenience yield (y) that the holder of the physical commodity enjoys. In India, the risk‑free rate is often approximated by the yield on government securities.
When storage costs are high (e.g., for oil) and convenience yield is low, futures tend to trade at a premium to spot. Conversely, for commodities with high convenience yield (e.g., agricultural products during harvest), futures may trade at a discount.
Exam questions may present a set of rates and ask you to compute the theoretical futures price or to identify whether the futures is at a premium or discount. Remember to convert percentages to decimals and keep the time horizon in years.
- Premium = F > S; Discount = F < S.
- Higher r or u pushes F up; higher y pushes F down.
Risk Management Tools for Derivatives
Portfolio managers use derivatives to hedge market risk, commodity price risk, and foreign‑exchange risk. The primary tools are hedging with futures, protective options, and dynamic margin management through daily mark‑to‑market (MTM) settlement.
Margin requirements act as a safety buffer. SEBI mandates an initial margin (usually 5‑10% of contract value) and a variation margin that reflects daily price movements. Failure to meet margin calls results in a forced liquidation of positions.
For exam preparation, focus on how to calculate the number of contracts needed for a hedge (hedge ratio = exposure ÷ contract size) and the impact of MTM on cash flows.
- Hedge ratio = Value of exposure ÷ (Contract size × Futures price).
- Mark‑to‑market = Daily profit/loss added/subtracted from margin account.
Scenario
An Indian exporter expects to receive USD 500,000 in 90 days. The current USD/INR spot rate is 82.00 and the 3‑month USD futures price is 82.30. The exporter wants to lock in the INR value using a futures contract.
Solution
Step 1: Determine contract size – each USD futures contract on NSE represents USD 1,000. Number of contracts needed = 500,000 ÷ 1,000 = 500 contracts. Step 2: Lock‑in rate using futures price of 82.30. Expected INR proceeds = 500,000 × 82.30 = 41,150,000 ₹. Step 3: On expiry, the exporter sells the futures (short position) at 82.30 while receiving USD 500,000 in the spot market at the prevailing spot rate (assume it is 82.10). The futures profit = (82.30‑82.10) × 500,000 = 0.20 × 500,000 = 100,000 ₹, which offsets the spot loss of (82.10‑82.00) × 500,000 = 0.10 × 500,000 = 50,000 ₹. Net INR received = 41,150,000 ₹ + 100,000 ₹ – 50,000 ₹ = 41,200,000 ₹, close to the locked‑in value.
Conclusion
The futures hedge effectively locked the INR value, demonstrating how a simple futures position can protect against adverse currency movements—a typical NISM scenario.
Taxation Overview – Commodity vs Currency Derivatives
Gains from commodity derivatives are taxed as business income under the head "Profits and Gains of Business or Profession". The applicable tax rate follows the individual's slab rates, and losses can be set off only against other business income.
Currency derivative gains, when the contracts are used for hedging, are also treated as business income. However, if the contracts are held for speculation, the gains are taxed as "Capital Gains" – short‑term if the holding period is less than 36 months, long‑term otherwise, with rates of 15% (STCG) and 10% (LTCG) after indexation.
For the exam, remember the key distinction: commodity gains are always business income, while currency gains depend on the purpose (hedge vs speculation). Also note that the tax audit threshold for derivative trading is ₹10 crore turnover.
- Commodity – Business income, loss set‑off within business.
- Currency – Hedge = business income; Speculation = capital gains.
Do not assume all derivative gains are taxed uniformly. Commodity gains are never capital gains; currency gains depend on hedging intent.
Common Mistakes & Tips for the Exam
One frequent error is mixing up the definitions of "premium" and "margin". Premium is the price paid for an option; margin is the collateral required for futures and for option writers. The exam will test this distinction explicitly.
Another pitfall is forgetting the sign convention in payoff calculations. For a long futures position, profit = (F_{exit} – F_{entry}) × contract size. For a long call option, profit = max(0, S_{spot} – K) – premium.
Finally, always check the regulatory jurisdiction before answering a question about reporting or margin. If the instrument is exchange‑traded, think SEBI; if it is an OTC forward, think RBI.
- Premium ≠ Margin.
- Use correct sign for long vs short positions.
- Identify regulator based on contract type.
⭐Exam Takeaways
- Commodity derivatives are contracts on physical goods; currency derivatives are contracts on exchange rates.
- Futures and options are exchange‑traded and regulated by SEBI; forwards and swaps are OTC and fall under RBI.
- The cost‑of‑carry formula F = S × e^{(r+u‑y)T} prices commodity futures; higher financing or storage costs raise futures price.
- Hedging ratio = Exposure ÷ (Contract size × Futures price); daily MTM ensures margin adequacy.
- Tax: Commodity gains = business income; Currency gains = business income if hedged, otherwise capital gains.
- Premium is the price of an option; margin is the collateral for futures and option writers.
- Remember regulator split: SEBI for exchange‑traded, RBI for OTC currency contracts.
