Consider the following spot interest rates for maturities of one, two, three, and four years.
r_1 = 4.8%; r_2 = 5.2%; r_3 = 5.9%; r_4 = 6.5%
What is the percentage forward rate f_(1,3), where f_(1, k) refers to a forward rate for the period beginning in one year and extending for k years?
(Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.)
To compute the forward rate we will use the following formula:
[ 1 + r ( T* + K ) ]( T* + K ) = [ 1 + r ( T* ) ]T* x [ 1 + f ( T* , K ) ]K
= In the above formula these are the notations used:
r = Rate of Interest
T* = Time after which the loan will start, which in our case is 1 year
K refers to the tenure of the loan which in our case is 3 years
Now we shall plug the above figures in the formula mentioned above:
[ 1 + r ( 1 + 3 ) ](1 + 3) = [ 1 + r (1) ]1 x [ 1 + f (1 , 3 ) ]3
r (1 + 3 ) = Rate of interest of year 4 = 6.5 % or 0.065
r (1) = Rate of Interest of year 1 = 4.8% or 0.048
Plugging these figures in the above mentioned equation we will get
(1 + 0.065 )4 = (1 + 0.048)1 x [(1 + f (1,3) ]3
= By solving the above equation we will get percentage forward rate of f_(1,3) to be equal to 7.07% approximately.
