http://practicalfinancialengineer.info/Jokyuhen4.4.1_Appendix.html In financial mathematics, the Hull–White model is a model of future interest rates. In its most generic formulation, it belongs to the class of no-arbitrage models that are able to fit today's term structure of interest rates. It is relatively straightforward to translate the mathematical description of the evolution of future interest rates onto a tree or lattice and so interest rate derivatives such as bermudan swaptions can be valued in the model. Web14 aug. 2024 · Pricing. From the fundamental theorem of asset pricing, we obtain P(t, T) = EQ[exp( − ∫T trsds) Ft]. You can thus price bonds by knowing the short rate. Regarding bond options, you can write down a PDE similar to the Black-Scholes PDE and solve it easily in closed-form: Pt + μ(t, r)Pr + 1 2σ(t, r)2Prr − rP = 0. drawing banaue rice terraces
