Hull-White Model

Framework

The Hull-White model is a widely used mathematical framework in quantitative finance for modeling the evolution of interest rates. It is an extension of the Vasicek model, incorporating time-dependent parameters that allow it to fit the initial term structure of interest rates perfectly. This model is a one-factor or two-factor short-rate model, capturing mean reversion in interest rates. It provides a robust foundation for valuing interest rate derivatives. The model offers analytical tractability.
