Answer:
Gringotts Bank real interest rate = 20% - 25% = -5%
Explanation:
real interest rate = nominal interest rate - inflation rate
the inflation rate between year 1 and year 2 = [(CPI year 2 - CPI year 1) / CPI year 1] x 100 = [(150 - 120) / 120] x 100 = (30 / 120) x 100 = 0.25 x 100 = 25%
Gringotts Bank real interest rate = 20% - 25% = -5%
since the interest rate is negative, that means that Gringott Bank is actually losing money by lending it at 20% since the inflation rate is much higher.
The bank's real interest rate is -5%.
Calculation of the bank real interest rate:
Since we know that
real interest rate = nominal interest rate - inflation rate
Here, the nominal interest rate is 20%
And, the inflation rate is
= [(CPI year 2 - CPI year 1) / CPI year 1] x 100
= [(150 - 120) / 120] x 100
= (30 / 120) x 100
= 0.25 x 100
= 25%
So, the real interest rate is
= 20% - 25%
= -5%
Therefore, we can conclude that the The bank's real interest rate is -5%.
