Assume current 1 year bond rate is 1%, 2 year bond rate is 1.5% and 3 year bond rate is 2%. Using pure expectation theory, calculate the expected 1- year rate one year from now? Using pure expectation theory, calculate expected 1-year rate two years from now?
Formula :
According to expectation theory we have :
Rn = (r0 + r1 + r2 --------------rn-1)/n
where Rn = n year bond rate and rn = expected 1-year rate n years from now
According to above formula we have :
R1 = (r0)/1 => r0 = R1 = 1%
Now, R2 = (r0 + r1)/2 => 1.5 = (1 + r1)/2 => r1 = 2%
Similarly, R3 = (r0 + r1 + r2)/3 => 2 = (1 + 2 + r2)/3 => r2 = 3%
Thus, Expected 1-year rate two years from now = r2 = 3%
Hence, Expected 1-year rate two years from now = 3%
