In this chapter, we explore two of the most influential frameworks for modeling the evolution of interest rates: the Heath–Jarrow–Morton (HJM) model and the Brace–Gatarek–Musiela (BGM) model. These forward-rate–based approaches extend beyond short-rate models by directly describing the dynamics of the entire forward rate curve, providing a more flexible and market-consistent framework for pricing interest rate derivatives.

Heath–Jarrow–Morton and BGM Models: Advanced Forward Rate Dynamics and Derivative Pricing with Boost

摘要

In this chapter, we explore two of the most influential frameworks for modeling the evolution of interest rates: the Heath–Jarrow–Morton (HJM) model and the Brace–Gatarek–Musiela (BGM) model. These forward-rate–based approaches extend beyond short-rate models by directly describing the dynamics of the entire forward rate curve, providing a more flexible and market-consistent framework for pricing interest rate derivatives.
