### A swaption, also known as a swap option, refers to an option to enter into an interest rate swap or some other type of swap. In exchange for an options premium, the buyer gains the right but not the obligation to enter into a specified swap agreement with the issuer on a specified future date.

Another challenge is the use of interest rate models. To determine the vega measure, we require the interest rate model to be (1) accurate in pricing the swaptions, (2) stable in the estimated parameters without overspeciﬂcation, and (3) computationally e–cient. Despite the prevalent use of arbitrage-free interest rate models, thus far Another Greek option, the gamma, is an expression of the changes in the position size (i.e. the changes in the delta) as it corresponds with changes in the level of interest rates, while vega is the sensitivity of the portfolio to changes in implied volatilities for at-the-money options associated with the maturity bucket in question. That may be important, for example, if the portfolio

### For all of these interest rate models, the calibration instruments (the market data) are interest rate caplets/floorlets and European-style swaptions. The functional forms of the modeled processes and the parameters associated with each model are shown in Table 1.
