Answer:
4%
Explanation:
We start with the nominal rate of return and then we adjust it to inflation.
real rate of return = nominal rate of return - inflation rate = 6.9% - 2% = 4.9%
finally we must subtract the maturity risk premium (MRP) of the bonds:
bond yield = real rate of return - MRP = 4.9% - 0.9% = 4%
