The lender and borrower expect inflation rates of 5% in 2019, 4.5% in 2020, and 3% in 2021. What is the geometric average of the expected inflation rates? If the lender requires a real rate of interest of 5%, what nominal rate would (s)he set for a 3 year loan (assume the loan is structured such that principle and interest are due in one lump sum at loan maturity)?
