Final answer:
The maturity risk premium for the 3-year Treasury security is 0.70%, calculated by subtracting the sum of the real risk-free rate and expected inflation rate from the nominal interest rate.
Step-by-step explanation:
The maturity risk premium (MRP) for the 3-year Treasury security can be determined by separating the components of the nominal interest rate. We know the nominal interest rate (3.70%), the real risk-free rate (r*) (0.75%), and the expected inflation rate (2.25%). The nominal interest rate is the sum of these figures plus the MRP. To calculate MRP, we use the following formula:
Nominal Interest Rate = r* + Inflation Premium + MRP
We rearrange this to solve for MRP:
MRP = Nominal Interest Rate - (r* + Inflation Premium)
Therefore:
MRP = 3.70% - (0.75% + 2.25%) = 0.70%
The maturity risk premium for the 3-year security is 0.70%.
