The purpose of this advanced level seminar is to give you a good understanding of interest rate models and their uses in option pricing and risk management. We first present and explain important concepts such as the term structure of interest rates and the term structure of volatility.

We then take at closer look at various processes for interest rate evolvement over time, and we explain how interest rate volatility can be modelled in these processes using models such as GARCH and EWMA (Exponentially Weighted Moving Average). We also explain various approaches to modelling, including the use of partial differential equations and "Martingales".

Next, we present and explain a number of models for interest rate processes, including "Equilibrium" models such as the Rendleman-Barter and Cox-Ingersoll-Ross and "No-arbitrage" models - with and without mean reversion features. This class of models includes single-factor models such as the Ho-Lee, Vasicek, Hull-White, Black-Derman-Toy as well as multi-factors models such as Longstaff-Schwartz. We also present the popular "Libor Market", or BGM (Brace-Gatarek-Muselia) model, which is widely used by practitioners. We discuss the important characteristics and parameters of these models, and we demonstrate how they can be implemented in practice.

Finally, we explain and illustrate how these models can be used for pricing and risk assessment of interest rate options such as Caps, Floors, Swaptions, Delivery Options, Prepayment Options and Defaultable Bonds. We also demonstrate the pricing and hedging of more advanced structures such as "Constant Maturity Swaps" (convexity adjustment) and of path-dependent option structures (using Monte Carlo simulation).
