Jump to navigation Jump to search A swaption is an option granting its owner the right but not the obligation to enter into an underlying swap. A payer swaption gives the owner of the swaption the right to enter into a swap where they pay the fixed leg and receive the floating leg. A receiver yen valuation gives the owner of the swaption the right to enter into a swap in which they will receive the fixed leg, and pay the floating leg. In addition, a “straddle” refers to a combination of a receiver and a payer option on the same underlying swap.
The participants in the swaption market are predominantly large corporations, banks, financial institutions and hedge funds. End users such as corporations and banks typically use swaptions to manage interest rate risk arising from their core business or from their financing arrangements. For example, a corporation wanting protection from rising interest rates might buy a payer swaption. Legally, a swaption is a contract granting a party the right to enter an agreement with another counterparty to exchange the required payments.
There are three main categories of Swaption, although exotic desks may be willing to create customised types, analogous to exotic options, in some cases. Bermudan swaption, in which the owner is allowed to enter the swap on multiple specified dates. European swaption, in which the owner is allowed to enter the swap only on the expiration date. These are the standard in the marketplace. American swaption, in which the owner is allowed to enter the swap on any day that falls within a range of two dates.
Addressing this, quantitative analysts value swaptions by constructing complex lattice-based term structure and short rate models that describe the movement of interest rates over time. In valuing European swaptions using the Black model, the underlier is treated as a forward contract on a swap. Here, as mentioned, the forward price is the forward swap rate.
