Solution by Steps
step 1
Calculate the real interest rate with the expected inflation rate: The real interest rate can be calculated using the formula r=iπer = i - \pi_e, where rr is the real interest rate, ii is the nominal interest rate, and πe\pi_e is the expected inflation rate
step 2
Calculate the real interest rate with the actual inflation rate: If the actual inflation rate is lower than the expected inflation rate, the real interest rate will be higher than initially calculated. This can be represented as ractual=iπactualr_{actual} = i - \pi_{actual}, where πactual<πe\pi_{actual} < \pi_e
step 3
Analyze the impact on Tyrion and the bank: A higher real interest rate means that the purchasing power of the money Tyrion receives from the bank increases, benefiting Tyrion. Conversely, the bank receives money back that has a higher purchasing power than expected, which is a disadvantage for the bank
Answer
E
Key Concept
Real Interest Rate and Inflation
Explanation
When the actual inflation rate is lower than the expected inflation rate, the real interest rate is higher, benefiting the depositor (Tyrion) and disadvantaging the bank.
