Answer:
expected real rate = 1%
Explanation:
Given data:
for 30 year, interest rate = 4%
for 10 year, interest rate = 2.5%
inflation rate 1.5% for over next 10 year
0.2% for maturity risk premium
Expected real rate of return on 10 yr U.S treasury bond is calculated as
expected real rate = rate of return - inflation rate
putting all value to get real rate of return value
expected real rate = 2.5% - 1.5%
expected real rate = 1%
