The volatility of the forward is described by a parameter . SABR is a dynamic model in which both F {\displaystyle F} and σ {\displaystyle \sigma } are represented by stochastic state variables whose time evolution is given by the following system of stochastic differential equations :
This forward contract is free, and, presuming the expected cash arrives, exactly matches the firm's exposure, perfectly hedging their FX risk. If the cash flow is uncertain, a forward FX contract exposes the firm to FX risk in the opposite direction, in the case that the expected USD cash is not received, typically making an option a better choice.
