This master thesis examines the pricing and hedging of Bermudan swaptions within the context of two-factor short-rate models. Considering both the Two-Factor Hull-White model and the related Linear Gaussian Two-Factor model, the analytical price of European swaptions is derived and the models calibration capabilities to these products are investigated. Furthermore, it is shown how to approach the particularities on the European swaption market, arising from the current negative interest rate environment and how to incorporate discounting based on Overnight Index Swaps (OIS) in the valuation process in the context of multi-curve bootstrapping. For the pricing of the Bermudan swaption, the construction of multivariate lattices for one-factor and two-factor diffusion processes is examined. The methodology to create and adjust a two-dimensional binomial tree for the short-rate in the Linear Gaussian Two-Factor model is presented and a pricing routine based on the lattice is developed. Finally, the performance and the outcome of the pricing routine is analyzed and assessed. In addition, with the help of principal component analysis it is shown how to hedge Bermudan swaptions against movements in the underlying interest rate term structure. For this purpose, a hedging portfolio based on co-terminal European swaptions is constructed and the performance of the hedging approach is tested within a backtest. The approach is further developed by incorporating the Bermudan swaptions sensitivity to implied normal volatilities and finally, the impact of this incorporation is examined.
