The Implied Rate is an interest rate equal to the difference between the spot rate and the forward or futures rate. The implied rate gives investors a way to compare returns across investments. The implied rate is calculated by finding the forward rate that would give a bond with a given maturity a zero yield. To find the forward rate, you simply need to multiply your desired future price by that future yield. For example, a 10 year bond earning 5% would have an implied yield of 5%.The implied rate is an interest rate equal to the difference between the spot rate and the forward or futures rate. The implied rate gives investors a way to compare returns across investments. This interest rate is derived by finding the spot interest rate that yields a fixed profit margin on an investment, and then subtracting the cost of carrying a position in a future or forward contract. When trading in different maturities, it is common to find a certain implied interest rate for trading in various bonds and bond issues.
