When the volatility and drift of the instantaneous forward rate are assumed to be deterministic , this is known as the Gaussian Heath—Jarrow—Morton HJM model of forward rates. It has its critics, however, with Paul Wilmott describing it as " The key to these techniques is the recognition that the drifts of the no-arbitrage evolution of certain variables can be expressed as functions of their volatilities and the correlations among themselves. In other words, no drift estimation is needed. Models developed according to the HJM framework are different from the so-called short-rate models in the sense that HJM-type models capture the full dynamics of the entire forward rate curve , while the short-rate models only capture the dynamics of a point on the curve the short rate. However, models developed according to the general HJM framework are often non- Markovian and can even have infinite dimensions.

This is how to implement the Heath-Jarrow-Morton interest rate model used for mapping forward curves to price interest rate swaps and other derivatives based on forward rates. This is based on a project I did to get my Certificate in Quantitative Finance. Skip to content.
