Consider a one-year interest rate swap with a notional value of 3000. Determine the swap interest rate per quarter.
Answer-
We need to first calculate the discount factors
Z 90 = 1 / 1 + [ ( 0.022 x 90 / 360) ]
Z 90 = 1 / [1 + 0.0055]
Z 90 = 1 / 1.0055
Z 90 = 0.9945
Z 180 = 1 / 1 + [ ( 0.028 x 180 / 360 )]
Z 180 = 1 / [1 + 0.014 ]
Z 180 = 1 / 1.014
Z 180 = 0.9862
Z 270 = 1 / 1 + [ ( 0.031 x 270 / 360 )]
Z 270 = 1 / [1 + 0.02325 ]
Z 270 = 1 / 1.02325
Z 270 = 0.9773
Z 360 = 1 / 1 + [ ( 0.037 x 360 / 360 )]
Z 360 = 1 / [1 + 0.037 ]
Z 360 = 1 / 1.037
Z 360 = 0.9643
The swap interest rate per quarter = 1 - Z 360 / ( Z 90 + Z 180 + Z 270 + Z 360)
The swap interest rate per quarter = 1 - 0.9643 / ( 0.9945 + 0.9862 + 0.9773 + 0.9643)
The swap interest rate per quarter = 1 - 0.9643 / 3.9223
The swap interest rate per quarter = 0.0357 / 3.9223
The swap interest rate per quarter = 0.009102
The swap interest rate per quarter = 0.9102 %
The swap interets rate annually = 0.9102 % x 360 / 90 = 3.641 %
For the notional value of 3000, the quarterly amount will be = 0.9102 % x 3000 = 0.009102 x 3000 = 27.306
