What are Interest Rate Futures?

Buying an interest rate futures contract allows the buyer of the contract to lock in a future investment rate; not a borrowing rate as many believe. Interest rate futures are based off an underlying security which is a debt obligation and moves in value as interest rates change.

When interest rates move higher, the buyer of the futures contract will pay the seller in an amount equal to that of the benefit received by investing at a higher rate versus that of the rate specified in the futures contract. Conversely, when interest rates move lower, the seller of the futures contract will compensate the buyer for the lower interest rate at the time of expiration .

To accurately determine the gain or loss of an interest rate futures contract, an interest rate futures price index was created. When buying, the index can be calculated by subtracting the futures interest rate from 100, or (100 — Futures Interest Rate). As rates fluctuate, so does this price index. You can see that as rates increase, the index moves lower and vice versa.

How do you calculate the gain or loss on the futures contract?

Typically, the interest rate futures contract has a base price move (tick) of .01, or 1 basis point however, some contracts have a tick value of .005 or half of 1 basis point. For example, for Eurodollar contracts, a tick is worth $12.50 and a move from 94 to 94.50 would result in a $1250 gain per contract for someone who is long the futures.

Hedging with futures

Many participants in the interest rate futures market hedge their positions that have an interest rate risk with an offsetting futures contract. As the hedge becomes profitable and traders see less risk in the market, the hedge will be peeled off.

Other participants will use interest rate futures to hedge forward borrowing rates. For example, it is currently March and I need to borrow money in June for 1 month at Libor plus 2. The current LIBOR rate is 2.75% and let’s say the 3 month LIBOR futures are 3%. I will basically be locking in a 5% forward rate by shorting or selling the LIBOR June1 month LIBOR futures contracts.
