Interest rate futures are a type of futures contract that are based on a financial instrument which pays interest. It is a contract between a buyer and a seller which agrees to buy and sell a debt instrument at a future date when the contract expires at a price that is determined today.

Some of these futures may require the delivery of specific types of bonds, mostly government bonds on the delivery date.

These futures may also be cash-settled in which case, the one who holds the long position receives and one who holds the short position pays. These futures are thus used to hedge against or offset interest rate risks. Which means investors and financial institutions cover their risks against future interest rate fluctuations with these.

These futures can be short or long term in nature. Short term futures invest in underlying securities that mature within a year. Long term futures have a maturity period of more than one year.

Pricing for these futures is derived by a simple formula: 100 – the implied interest rate. So a futures price of 96 means that the implied interest rate for the security is 4 percent.

Since these futures trade in government securities, the default risk is nil. The prices depend only on the interest rates.

Features of interest rate futures

Now that we have had a look at what is interest rate futures, we will look at some key features.

  1. Underlying asset:The underlying asset is the interest-bearing security on which the contract is based. In case of an interest rate futures contract, it is either a Government bond or a T-Bill.
  2. Expiration date:This is the final date future for settlement of the contract which is pre-determined.
  3. Size: This refers to the total amount of the contract. There is, however, a minimum requirement of Rs 2 lakh or 2,000 bonds if one wants to trade in these futures.
  4. Margin requirement:There is an initial amount required to enter into a futures contract. At the time of starting your trading, you will be required to pay an initial or upfront margin to your broker. This serves as a security deposit which the broker in turn has to submit to the exchange. For NSE, the minimum margin for cash-settled interest rate futures contract is 1.5 percent of the contract’s value subject to a maximum of 2.8 percent on the first day of trading. For 91-Days T-Bill futures contract the margin is 0.10 percent of the notional value of the futures contract on the first trading day. This becomes 0.05 of the notional value of futures contract after that.

How interest rate futures work

Since the interest rates and prices of bonds have an inverse relationship when interest rates rise, bond prices fall; the opposite happens when interest rates fall.

Let us say that an investor is holding a long position in a bond, so he expects to sell at a higher price. However, if interest rates rise, the value of the bond will fall, so rising interest rates are a risk for this investor. Since the bonds are an underlying asset in the contract, the bond prices will fall. Such investors can sell these futures so that they can repurchase them at a lower rate to counter the loss in the value of bonds he is holding.

Let us take an example. Let us assume that you have a home of a loan of Rs 50 lakh and you expect that due to RBI policies, the interest rates are going to go up in a certain period, let us say six months or one year. When interest rates go up, your EMI will also go up. To hedge the risk of rising EMIs when interest rates rise, you can sell an interest rate futures contract. If interest rates go up, the price of these future contract will fall, and you can repurchase them. The higher outgo in terms of EMI is offset to a certain extent by the difference in prices of futures and you are hedged against the risk of rising interest rates.
