A. B. C. D. E.Explanation
The real rate of interest is simply the nominal rate less inflation. Therefore, the real rate is not directly effected by inflation, while the nominal rate would rise as inflation rises.
Inflation and interest rates are closely related, and changes in inflation can indeed impact interest rates. When considering the impact of inflation on interest rates, it's important to distinguish between nominal interest rates and real interest rates.
Nominal interest rates are the rates that are explicitly stated on loans or investments. They represent the return or cost of borrowing money without accounting for the impact of inflation. On the other hand, real interest rates take into account the effects of inflation and reflect the actual purchasing power of the money being borrowed or invested.
Now, let's examine the given answer choices and determine the correct option:
A. increases the real rate; increases the nominal rate: This option suggests that inflation increases both the real interest rate and the nominal interest rate. It implies that inflation impacts both the cost of borrowing money and the purchasing power of money. While inflation typically leads to an increase in nominal interest rates, the impact on real interest rates is more complex. Inflation erodes the purchasing power of money, so lenders will require higher nominal interest rates to compensate for the expected loss in the value of the money they lend. However, if inflation is anticipated or expected, borrowers may demand higher nominal interest rates to maintain the real value of their repayments. As a result, this option is incorrect.
B. has no direct impact on interest rates: This option suggests that inflation has no direct impact on interest rates. However, this statement is not accurate. Inflation does affect interest rates, both in terms of nominal interest rates and real interest rates. Therefore, this option is incorrect.
C. has no effect on the real rate; increases the nominal rate: This option states that inflation has no effect on the real interest rate but increases the nominal interest rate. This is closer to the reality of how inflation impacts interest rates. Inflation erodes the purchasing power of money, so lenders will generally require higher nominal interest rates to compensate for the expected loss in the value of the money they lend. However, the real interest rate, which accounts for inflation, may remain relatively stable if the increase in the nominal interest rate matches the rate of inflation. Therefore, this option is a plausible answer.
D. increases the real rate; has no effect on the nominal rate: This option suggests that inflation increases the real interest rate but has no effect on the nominal interest rate. Inflation erodes the purchasing power of money, so lenders generally require higher nominal interest rates to compensate for the expected loss in the value of the money they lend. This option contradicts the typical relationship between inflation and nominal interest rates. Therefore, this option is incorrect.
E. impossible to determine: This option suggests that it is impossible to determine the impact of inflation on interest rates. However, we can indeed analyze the relationship between inflation and interest rates, and there are established patterns and theories that explain this relationship. Therefore, this option is incorrect.
Considering the explanations above, the correct answer is:
C. has no effect on the real rate; increases the nominal rate
