Question
4. The one-year interest rate over the next 10 years will be: 3%,45%, 6%, 7.5%, 9%, 10.5%, 13%, 14.5%, 16%, and 17.5%. a. Using the expectations theory, what will be the interest rates on a three year bond, a six year bond and a nine year bond? b. A liquidity premium of 10 basis points is required for each year of bond maturity. Using the liquidity premium theory, what will be the interest rates on a three year bond, a six year bond and a nine year bond? 5. If the interest rates on one to five-year bonds are currently 4%, 5%, 6%, 7% and 8%, predict what the one year interest rate will be two years from now.Explanation / Answer
4)
a. 3 year bond rate = r1+r2+r3/3 = 3+4.5+6/3 = 4.5%
6 year bond rate = r1+r2+r3+r4+r5+r6/6 = 3+4.5+6+7.5+9+10.5/6 = 6.75%
9 year bond rate = r1+r2+r3+r4+r5+r6+r7+r8+r9/9 = 3+4.5+6+7.5+9+10.5+13+14.5+16/9 = 9.33%
we can also do it in more approximate way;
3 year bond rate:
(1+r)^3=(1.03)*(1.045)*(1.06);
Calculate for r, we get r = 4.4928%
Similarly for
6 year bond rate
(1+r)^6=(1.03)*(1.045)*(1.06)*(1.075)*(1.09)*(1.105)
We get r = 6.7193%
For 9 year bond rate r = 9.2502%
b)
3 year bond rate
we have to add the premium
(1+r) ^ 3 = (1.03)*(1.045)*(1.06) +0.003 = 4.5843%
0.003 is because per year 10 basis point(0.1%) so for 3 years it is 0.3%(0.003)
for 6 years it is 0.006
for 9 years it is 0.009
same way for 6 years bond r = 6.7914%
9 year bond rate r = 9.2993%
5)
one year rate one year from now = r11 = [(1+r2)^2/(1+r1)] - 1
r1 = rate at year one
r2 = rate at year 2
r11 = [(1+r2)^2/(1+r1)] - 1 = [(1.05)^2/(1.04)] - 1 = 6.009%
hence one year rate 2 years from now
= [(1+r3)^3 / (1+r1) * (1+r11)] - 1= [(1.06)^3 / (1.04)*(1.06009)] -1 = 8.029%
