Needs to be bootstraped? • Discountfactor for EONIA • 1 month Forward rate from 1 monthcurve • 3 month Forward rate from 3 monthcurve • Discountfactor for 6 month THE GIVEN DATA • Market Rates • Start dates and maturity dates • A swap for 20 yearsmaturity and 3month tenor
DiscountFactorformula (swaps): • If the market value of n=11 is missing, thenweuse market • value of n=10, and n=12 (INTRAPOLATION METHOD). • Wecanuse the market value of n=9,n=10 to calculate the • missing market value n=11(EXTRAPOLATION METHOD).
The Formula for interpolation is : To calculate D11 weneed to calculate D12 first, the formula is:
Forward rates • Finally we’ve got all the variables which are needed for calculating the Forward rates
Swap rates The par rate for a Swap is calculated as:
