NISM Series IV: Exchange Traded Interest Rate Futures – Complete Notes
This blog post covers Chapter 3 of the NISM Series IV Interest Rate Derivatives syllabus — Exchange Traded Interest Rate Futures. This chapter carries good weightage in the exam and tests your knowledge of futures terminologies, FRA vs IRF comparison, and futures pricing. Read these notes carefully before your NISM IV exam.
What are Futures Markets?
Futures markets were developed to overcome the limitations of forward contracts. A futures contract is an agreement made through an organized exchange to buy or sell a fixed amount of a commodity or a financial asset on a future date at an agreed price.
Simply put: Futures = Standardised Forward Contracts traded on an Exchange.
The clearing corporation guarantees settlement of trades done on the exchange.
What are Interest Rate Futures (IRF)?
Interest Rate Futures (IRF) are standardized interest rate derivative contracts traded on a recognized stock exchange to buy or sell a notional security or any other interest-bearing instrument or an index of such instruments or interest rates at a specified future date, at a price determined at the time of the contract.
Important: Interest Rate Futures include money market futures as well.
Futures Terminologies — Must Know for NISM Series IV
All these terms are frequently tested in the NISM IV exam. Learn them clearly:
Underlying Asset
The value of a futures contract is derived from the value/price of a certain underlying asset.
Spot Price / Rate
The price/interest rate at which the underlying asset trades in the spot market.
Futures Price / Rate
The current price/rate of the specified futures contract.
Contract Cycle
The period over which a contract trades.
Expiry Date
Also called the last trading day of the contract. It is the day on which trading ceases in the contract.
Tick Size
The minimum move allowed in the price/rate quotations.
Contract Size / Lot Size
Futures contracts are traded in lots. Contract size specifies the amount of the asset that has to be delivered for a single contract.
Contract Value
Contract Value = Price / Rate × Contract Multiplier (or Lot Size or Contract Size)
Trading Hours
The time during which trading is allowed on the exchange trading platform.
Base Price
Base price generally acts as the reference price for trading at the start of the day.
Price Band
The price range (maximum and minimum price) within which a contract can be traded on any given day.
Mark to Market (MTM)
The positions in futures contracts for each member are marked-to-market to the daily settlement price of the futures contracts at the end of each trading day.
Final Settlement
Final settlement can be cash settled or physically settled. In the case of cash settlement, only the profit and loss resulting from positions is paid/received from the participants.
Open Interest
Open interest is the total number of contracts outstanding (yet to be settled) for an underlying asset.
Comparison of FRAs vs Interest Rate Futures (IRF)
This comparison is one of the most important topics for the NISM Series IV exam.
| Parameter | Forward Rate Agreements (FRA) | Interest Rate Futures (IRF) |
|---|---|---|
| Operational Mechanism | Bilateral – Over the Counter (OTC) | Through Centralized Trading Exchanges |
| Terms of Contracts | Non-Standardized | Standardized Contract |
| Underlying | Usually Interest Rate | Interest Rate, Index |
| Price Discovery | Not efficient; through negotiation | Through free interaction of buyers and sellers |
| Liquidation Profile | Low | High |
| Advantages | Can provide perfect hedge (customized). Less operational issues related to margin and MTM. | Price transparency. Elimination of counterparty credit risk (clearing corporation guarantees settlement). Access to all participants. Credit agnostic. Lower liquidity risk. Generally lower impact cost. |
| Limitations | Liquidity risk. Counterparty risk. Not accessible for all market participants. | May lead to imperfect hedge as amounts and settlement dates are standardized. Operational issues related to MTM settlement and margin. |
Forward Rate
A forward rate is an interest rate applicable to a financial transaction that will take place in the future. Forward rates can be determined using spot rates. In an efficient market, the same returns are received for investment made over one long term or multiple shorter terms by reinvesting the maturity proceeds.
Pricing of Interest Rate Futures Financing Cost
Financing cost is the relationship between futures prices and spot prices. It measures the interest paid to "finance" or "carry" the asset till the expiry date of the contract.
Income on Cash Position
In case of fixed income securities, income is accrued on a daily basis. The income on cash position = Accrued interest expected to be received on expiry + Coupon payment received during the contract + Interest received on investment of such coupon payments.
Futures Bond Price Formula
Future Bond Price = Cash Price + Financing Cost – Income on Cash Position
Why Use Interest Rate Futures?
Interest rate derivatives are most often used to:
- Hedge against interest rate risk — Interest rate risk exists in any interest-bearing asset (loan or bond) due to the possibility of a change in the asset's value resulting from variability of interest rates.
- Speculate on the direction of future interest rate moves.
Key Differences: Forwards vs Futures
| Feature | Forwards | Futures |
|---|---|---|
| Trading venue | OTC (bilateral) | Exchange |
| Standardization | Non-standardized | Standardized |
| Counterparty risk | High | Low (clearing corporation guarantee) |
| Liquidity | Low | High |
| Margin requirement | No | Yes (MTM daily) |
| Customization | High (perfect hedge possible) | Low (standardized — imperfect hedge) |
Additional Important Points for NISM IV Exam
- Futures are traded in lots; lot size is fixed by the exchange.
- Daily MTM settlement ensures losses/profits are settled every day — this is different from forwards where settlement happens only at expiry.
- Open Interest is a key indicator of market activity. Rising open interest with rising prices generally signals a bullish trend.
- Futures prices are determined by the cost of carry model: Futures Price = Spot Price × e^(r-d)×T, where r = risk-free rate, d = dividend/coupon yield, T = time to expiry.
Quick Recap for NISM Series IV Exam
- Futures = Standardized forward contracts traded on exchange.
- IRFs include money market futures.
- Key terms: Spot price, futures price, lot size, contract cycle, expiry date, tick size, MTM, open interest.
- MTM settlement = daily profit/loss settlement.
- FRA vs IRF — FRA is OTC, customized, bilateral; IRF is exchange-traded, standardized, transparent.
- Future Bond Price = Cash Price + Financing Cost – Income on Cash Position.
