Heath-Jarrow-Morton (HJM) Model: What it Means, How it Works - Investopedia
WEBNov 1, 2023 · The HJM Model predicts forward interest rates, with the starting point being the sum of what’s known as drift terms and diffusion terms. The forward rate drift is driven by volatility,...
Heath–Jarrow–Morton framework - Wikipedia
WEBThe Heath–Jarrow–Morton (HJM) framework is a general framework to model the evolution of interest rate curves – instantaneous forward rate curves in particular (as opposed to simple forward rates). When the volatility and drift of the instantaneous forward rate are assumed to be deterministic, this is known as the Gaussian Heath–Jarrow ...
Heath-Jarrow-Morton Model - Overview, Formula, Assumptions, …
WEBThe Heath-Jarrow-Morton Model – also known as the HJM Model – is a framework to represent forward interest rates using an existing term structure of interest rates. The model was created based on the work developed by David Heath, Robert A. Jarrow, and Andrew Morton during the late 1980s.
WEBforward interest rates are completely determined by the volatility structure of these rates. The object of this note is informally demonstrate why the relationship they use must hold.

WEBThe key result in this framework is that the drift of the forward rate f ( t, T) under the risk-neutral measure Q is determined by the volatility. This is different to short-rate models, where we are free to specify the drift for the short rate.

WEBThis is the approach taken by the so-called Heath–Jarrow–Morton (HJM) models studied in this chapter. The HJM models specify the dynamics of all forward interest rates and a key result is a link between the drift and volatilities of the forward rates.
Heath-Jarrow-Morton Model - What Is It, Formula, Assumptions
WEBAug 21, 2024 · The drift term α (t, T) and the volatility term σ (t, T) can be functions of time t and maturity T, determining the behavior and characteristics of the forward rates. These functions can be calibrated to historical market data or estimated using other models or statistical techniques.
