Answer:
a) Cash flow in year 1
Principal = 1000 * 1.08 = 1,080
Cash flow (Interest) = 1,080 * 0.04 = $43.20
b) Cash flow in year 2
Principal = 1080 * 1.08 = 1,166.40
Cash flow (Interest + principal) = $1,213.06
Interest = 1,166.40 * 0.04 = $46.66
Principal = $1,166.40
c) Real rate of return = {(1 + Nominal rate) / (1 + interest rate)} - 1
= {1.04/1.08} / 1
= -3.7%
Explanation:
Treasury Inflation protected securities (TIPS) are securities that take into cognizance inflation, thereby providing the investor with a real rate of return on investment.
For year 1, the principal invested i.e. face value of the bond increases with inflation as seen as calculated above and further increases in year 2 as the inflation rate affects both years.
Since the inflation rate is higher than the nominal rate of the investment, the result of this is that the real rate of return is in the negative.
