This master thesis deals with the valuation and hedging of multi-callable options on swap contracts, so-called Bermudan swaptions. The valuation of these options is more challenging than that of plain vanilla options. On each exercise date, the continuation value of the option is compared to the underlying's value, and a decision is made whether we continue to hold the option or exercise. For the continuation value of the option, we need to determine the expected value of the derivative conditioned on the information available on the exercise date. Instead of modeling the conditional expectation with binomial or trinomial trees, the term structure is modeled with the Hull-White or LIBOR market model, respectively, and the conditional expectation is determined using regression methods. A backward algorithm ultimately determines the value of the Bermudan swaption. Furthermore, we define the sensitivities of the Bermudan swaption to changes in the yield curve and the volatility in the swaption market and introduce the concept of Delta, Vega, and Delta-Vega Hedges. Finally, we perform a hedge backtest with real market data. Moreover, the master thesis highlights changes in the interest rate market implied by the subprime crisis and shows their implications on the pricing of derivatives.
