The real interest rate is the rate of interest an investor, saver or lender receives (or expects to receive) after allowing for inflation. It can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate.
The Fisher equation plays a key role in the Fisher hypothesis, which asserts that the real interest rate is unaffected by monetary policy and hence unaffected by the expected inflation rate. With a fixed real interest rate, a given percent change in the expected inflation rate will, according to the equation, necessarily be met with an equal ...

For instance, if a loan offers a 4% nominal interest rate and inflation is 2%, the real interest rate is approximately 2%. The world of finance has a somewhat different definition. It defines ...

If inflation is 10%, then the $110 in the account at the end of the year has the same purchasing power (that is, buys the same amount) as the $100 had a year ago. The real interest rate is zero in this case. The real interest rate is given by the Fisher equation: = + + where p is the inflation rate.
An interest rate cap is a derivative in which the buyer receives payments at the end of each period in which the interest rate exceeds the agreed strike price. An example of a cap would be an agreement to receive a payment for each month the LIBOR rate exceeds 2.5%.
The most influential reaction function is the Taylor rule, developed by economist John Taylor in 1993.The rule provides a systematic formula for setting the nominal interest rate based on four key variables: The deviation of current inflation rate from the central bank's target; The current inflation rate itself; The equilibrium real interest rate; and the output gap, measured as the ...
