Hull-white
WebThe Hull-White one-factor model describes the evolution of the short rate and is specified using the zero curve, alpha, and sigma parameters for the equation d r = [ θ ( t) − a ( t) r] d t + σ ( t) d W where: dr is the change in the short-term interest rate over a small interval, dt. r is the short-term interest rate.

Web28 okt. 2024 · We assume a probability space (Ω, F, Q) and a finite time horizon (0, T), with Ω being a sample space with outcome element ω, F being a σ-algebra, and Q being the risk-neutral probability measure on elements of F.The full-scale Heston-Hull-White model is defined, under the risk-neutral measure, by the following system of stochastic differential … 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 … Meer weergeven For the rest of this article we assume only $${\displaystyle \theta }$$ has t-dependence. Neglecting the stochastic term for a moment, notice that for $${\displaystyle \alpha >0}$$ the change in r is negative … Meer weergeven By selecting as numeraire the time-S bond (which corresponds to switching to the S-forward measure), we have from the fundamental theorem of arbitrage-free pricing, the value at time t of a derivative which has payoff at time S. Meer weergeven Even though single factor models such as Vasicek, CIR and Hull–White model has been devised for pricing, recent research has shown their potential with regard to forecasting. … Meer weergeven It turns out that the time-S value of the T-maturity discount bond has distribution (note the affine term structure here!) $${\displaystyle P(S,T)=A(S,T)\exp(-B(S,T)r(S)),}$$ where Meer weergeven However, valuing vanilla instruments such as caps and swaptions is useful primarily for calibration.

WebThe Hull-White process is constructed by passing the term-structure, a and sigma. To create the path generator, one has to provide a random sequence generator along with other simulation inputs such as timestep and `length.
