Real interest rate
Finance
Economics
(noun)
The rate of interest an investor expects to receive after allowing for inflation.
Examples of Real interest rate in the following topics:
-
Bond Prices in an Open Economy
- Thus, we deduct a country's inflation rate from the nominal interest rate, yielding the real interest rate.
- Consequently, the real interest rate equals 5% in Figure 10 while the amount of funds in the market is L*.
- If the world's real interest rate were 9%, then the domestic investors would invest their funds in the international market, earning a higher interest rate in Figure 10.
- If the world's real interest rate were 1%, then firms and the government would borrow at the cheap rates in Figure 10.
- However, a large country like the United States, Germany, or Japan would affect the world's real interest rate.
-
The Fisher Effect
- Investors and savers are concerned about the real interest rate because the real interest rate reflects the true cost of borrowing.
- The Fisher Effect relates nominal and real interest rates and we define the notation as:
- It equals a geometric average of the expected inflation rate and real interest rate.
- We calculated the real interest rate in Equation 3.
- We calculated the real interest rate in Equation 4.
-
Comparing Interest Rates
- The Fisher Equation is a simple way of determining the real interest rate, or the interest rate accrued after accounting for inflation.
- To find the real interest rate, simply subtract the expected inflation rate from the nominal interest rate.
- By the Fisher Equation, the real interest rates are 1% and 2% for Company 1 and Company 2, respectively.
- The nominal interest rate is approximately the sum of the real interest rate and inflation.

Differences Between Real and Nominal Rates
- The real rate is the nominal rate minus inflation.
- In the case of a loan, it is this real interest that the lender receives as income.
- If the lender is receiving 8% from a loan and inflation is 8%, then the real rate of interest is zero, because nominal interest and inflation are equal.
- The real rate 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: 1 + i = (1+r) (1+E(r)), where i = nominal interest rate; r = real interest rate; E(r) = expected inflation rate.
- The relationship between real and nominal interest rates is captured by the formula.
-
Macroeconomic Factors Influencing the Interest Rate
- Taylor explained the rule of determining interest rates using three variables: inflation rate, GDP growth, and the real interest rate.
- An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender in the market.
- The interest rates are influenced by macroeconomic factors.
- In this equation, it is the target short-term nominal interest rate (e.g., the federal fund rates in the United States), πt is the rate of inflation as measured by the GDP deflator, π*t is the desired rate of inflation, r*t is the assumed equilibrium real interest rate, yt is the logarithm of real GDP, and y*t is the logarithm of potential output, as determined by a linear trend.
- Taylor explained the rule in simple terms using three variables: inflation rate, GDP growth, and the equilibrium real interest rate.
-
Inflation Premium
- An inflation premium is the part of prevailing interest rates that results from lenders compensating for expected inflation by pushing nominal interest rates to higher levels.
- The Fisher equation in financial mathematics and economics estimates the relationship between nominal and real interest rates under inflation.
- In economics, this equation is used to predict nominal and real interest rate behavior.
- Letting r denote the real interest rate, i denote the nominal interest rate, and let π denote the inflation rate, the Fisher equation is: i = r + π.
- For example, if an investor were able to lock in a 5% interest rate for the coming year and anticipates a 2% rise in prices, he would expect to earn a real interest rate of 3%. 2% is the inflation premium.
-
International Fisher Effect
- The Fisher Effect relates the nominal interest rate to the rate of inflation and real interest rate.
- As long as the expected inflation and real interest rates are small, then the approximation will be accurate.
- For example, if the expected inflation, $\pi$, is 10% and nominal interest rate, i, equals 5%, subsequently, the real interest rate is approximately -5%.
- The International Fisher Effect relates the real interest rate to a nominal interest rate in a foreign country.
- Thus, both the foreign interest rate and change of currency exchange rate determine an investor's real return.
-
Interest Rate Levels
- An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender.
- An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender.
- Changes in interest rate levels signal the status of the economy.
- However, lowering interest rates can sometimes lead to the creation of massive economic bubbles, when a large amount of investments are poured into the real estate market and stock market.
- Because there is an excessive demand for real balances, the interest rate rises.
-
Price Risk
- Interest rates and bond prices carry an inverse relationship.
- Fixed-rate bonds are subject to interest rate risk, meaning that their market prices will decrease in value when the generally prevailing interest rates rise.
- When the market interest rate rises, the market price of bonds will fall, reflecting investors' ability to get a higher interest rate on their money elsewhere — perhaps by purchasing a newly-issued bond that already features the new higher interest rate.
- On the flip side, if the prevailing interest rate were on the decline, investors would naturally buy bonds that pay lower rates of interest.
- If there is any chance a holder of individual bonds may need to sell his bonds and "cash out", interest rate risk could become a real problem.

Interest Rates and Economic Rationale
- The interest rate is one of the primary influences on economic rationale.
- The interest rate is the rate at which interest is paid by a borrower (debtor) for the use of money borrowed from a lender (creditor).
- Interest rates also influence inflationary expectations.
- For example, low interest rates can lead to large amounts of investments poured into the real-estate market and stock market.
- The interest rates reached 14% in 1969 and lowered to 2% by 2003.
