What Are Currency Derivatives? USD-INR Futures and Options Explained

Short answer: Currency derivatives are contracts whose value is based on an exchange rate, for example USD-INR. In India they trade on NSE and BSE as currency futures and currency options. Businesses use them to lock in exchange rates and protect against currency movement.

What it is	Agreement to buy or sell a currency at a fixed rate on a future date	Right, not obligation, to buy (call) or sell (put) at a fixed rate
Upfront cost	Margin	Premium (buyer), margin (seller)
Risk for buyer	Unlimited both ways until closed	Limited to premium paid
Settlement in India	Cash-settled in rupees	Cash-settled in rupees

Contract basics for USD-INR

• Lot size: 1 lot = USD 1,000.
• Quote: rupees per 1 US dollar, for example 84.2500.
• Tick size: ₹0.0025, which equals ₹2.50 per lot.
• Expiry: monthly and weekly contracts, settled against the RBI reference rate.
• Trading hours: 9:00 am to 5:00 pm on exchange working days.

Contract details can be revised by the exchanges, so check the current specification on the NSE or BSE website.

A simple hedging example

An importer must pay USD 50,000 in two months. Today's futures price for that month is ₹84.50. The importer buys 50 lots of USD-INR futures.

• If the rupee weakens to ₹86, the dollars cost more, but the futures position gains about ₹1.50 × 50,000 = ₹75,000, offsetting the extra cost.
• If the rupee strengthens to ₹83.50, the futures lose about ₹50,000, but the dollars are cheaper to buy.

Either way, the effective rate stays close to ₹84.50. That certainty is the purpose of a hedge.

FAQs

Are currency derivatives the same as forex trading?

They are the regulated, exchange-traded form of currency trading available to Indian residents. "Forex trading" on overseas spot or CFD platforms is a different thing and is not permitted.

How much money is needed for one USD-INR lot?

Only the margin, which is a small percentage of the contract value and changes with volatility. Your broker's margin calculator shows the current figure.

Are currency derivatives risky?

Yes. They are leveraged instruments. A small move in the exchange rate produces a large percentage change in your margin.
