Bootstrapping at par rate Ellen Bjarnadóttir Mushegh Khalatyan Koorosh Feizi
The data given • Par rates • Start dates/Maturity dates The first steps The O/N discount factor and zero rates and The generalized formula for discount factor and zero rates up to the forward rate: and
The stub rate • Calculating the zero rate of the STUB (using linear interpolation) • Now, when we have the zero rates for the STUB, we calculate the discount factor for the STUB
fra rates • Discount factor • Zero rate
Approximation of swap rate • Use linear interpolation for the swap rate to calculate 1Y, 2Y, 3Y and up to 29Y • Use formula for the discount factor
Swap rates • Using those results of discount factors for the dates in between we get the discount factors and zero rates for the SWAPs for actual dates that we have got • Where • Now we can calculate the zero rate for the swaps
Forward rates • Finally we’ve got all the variables which are needed for calculating the Forward rates
