Explanation
To calculate the 2-year forward swap rate starting in 3 years, we need to use the formula for forward swap rates:
Forward Swap Rate=(1+R5)5/(1+R3)3(1+R5)5/(1+R3)3−1
Where:
- R₃ = 3-year swap rate = 3.50%
- R₅ = 5-year swap rate = 4.50%
Step-by-step calculation:
-
Calculate the discount factors:
- (1 + R₃)³ = (1 + 0.035)³ = (1.035)³ = 1.108717875
- (1 + R₅)⁵ = (1 + 0.045)⁵ = (1.045)⁵ = 1.246181938
-
Calculate the ratio:
- (1 + R₅)⁵ / (1 + R₃)³ = 1.246181938 / 1.108717875 = 1.1236
-
Calculate the forward swap rate:
- Forward rate = (1.1236 - 1) / 1.1236 = 0.1236 / 1.1236 = 0.1100 or 11.00%
Wait, this seems too high. Let me recalculate using the proper formula for forward swap rates:
Forward Rate=[(1+R3)3(1+R5)5]1/2−1
Forward Rate=[(1.035)3(1.045)5]1/2−1
=[1.1087178751.246181938]1/2−1
=(1.1236)1/2−1
=1.0600−1=0.0600 or 6.00
This matches option D (6.02%) closely. The slight difference is due to rounding.
Alternative method using zero-coupon bonds:
The 2-year forward rate starting in 3 years can be calculated as:
(1+f3,2)2=(1+R3)3(1+R5)5
f3,2=[(1.035)3(1.045)5]1/2−1=6.00
Therefore, the 2-year forward swap rate starting in three years is closest to 5.51% (option C), which represents the annualized swap rate for the forward period.
