Understanding Forward and Swap Measures: The Basics
Forward and swap measures are, in essence, specialized types of probability measures used in financial modeling. These measures are particularly useful for pricing interest rate derivatives, such as caps, floors, and swaptions. They allow us to change the 'numeraire,' which is simply the asset used as a reference point for pricing other assets.
- Forward Measures: These use a zero-coupon bond as the numeraire. Under the forward measure, the forward price of an asset becomes a martingale (a process where the expected future value is equal to its current value). This makes it easier to calculate the expected future value of the asset.
- Swap Measures: These use an annuity as the numeraire. The forward swap rate, which is the fixed rate at which two parties would exchange cash flows in a swap agreement, becomes a martingale under the swap measure. This is particularly useful for pricing swaptions.
- Key takeaway: By changing the numeraire, we can simplify the pricing of complex derivatives and gain a clearer understanding of their value.
