Question
6-3: The Determinants of Market Interest Rates
Problem 6-12
Maturity Risk Premium
An investor in Treasury securities expects inflation to be 2.35% in Year 1, 3.15% in Year 2, and 4.25% each year thereafter. Assume that the real risk-free rate is 1.75%, and that this rate will remain constant. Three-year Treasury securities yield 6.05%, while 5-year Treasury securities yield 7.20%. What is the difference in the maturity risk premiums (MRPs) on the two securities; that is, what is MRP5 - MRP3? Round your answer to two decimal places.

Explanation / Answer
Annual Inflation rate for 3 year treasury security =( (1+2.35%)*(1+3.15%)*(1+4.25%))^(1/3) - 1
Annual Inflation rate for 3 year treasury security = 3.25%
Annual Inflation rate for 5 year treasury security =( (1+2.35%)*(1+3.15%)*(1+4.25%)*(1+4.25%)*(1+4.25%))^(1/5) - 1
Annual Inflation rate for 5 year treasury security = 3.65%
Three-year Treasury securities yield = real risk-free rate + Inflaton Premium + maturity risk premiums
6.05%= 1.75% + 3.25% + maturity risk premiums)
Maturity risk premiums = 1.05%
Five-year Treasury securities yield = real risk-free rate + Inflaton Premium + maturity risk premiums
7.20% = 1.75% + 3.65% + maturity risk premiums
Maturity risk premiums = 1.80%
Differnce in MRP5 - MRP3 = 1.80 - 1.05
Differnce in MRP5 - MRP3 = 0.75%
Answer
0.75%
