Inflation-indexed securities(redirected from Inflation Indexed Security)
A bond or other fixed-rate security with an interest rate that varies according to inflation. An inflation-indexed bond, for example, may pay a fixed coupon plus an additional coupon with the amount adjusted every so often according to some inflation indicator, such as the Consumer Price Index. If these securities are held to maturity, then the investor guarantees that the return will exceed the rate of inflation. Inflation-indexed securities exist to provide a low-risk investment vehicle in which the return is guaranteed not to fall below the rate of inflation. See also: I Bond.
