Answer:
Japan
Step-by-step explanation:
Data provided in the question
Japan Nominal interest rate = 2.0%
U. S Nominal interest rate = 4.0%
Japan inflation rate = 0.50%
U.S inflation rate = 3.0%
Now the formula to compute the real interest rate is
Real interest rate = Nominal interest rate - inflation rate
For Japan, it is
= 2% - 0.50%
= 1.50%
For U.S, it is
= 4.0% - 3.0%
= 1.0%
So as we can see that highest rate interest rate is 1.50% i.e of Japan
