Endogenous short rate models are short rate models where the term structure of interest rates, or of zero-coupon bond prices (,), is an output of the model, so it is "inside the model" (endogenous) and is determined by the model parameters. Exogenous short rate models are models where such term structure is an input, as the model involves some ...
In financial mathematics, the Ho-Lee model is a short-rate model widely used in the pricing of bond options, swaptions and other interest rate derivatives, and in modeling future interest rates. [1]: 381 It was developed in 1986 by Thomas Ho [2] and Sang Bin Lee. [3] Under this model, the short rate follows a normal process:
The model is a short-rate model.In general, it has the following dynamics: = [() ()] + ().There is a degree of ambiguity among practitioners about exactly which parameters in the model are time-dependent or what name to apply to the model in each case.

It is a one-factor model; that is, a single stochastic factor—the short rate—determines the future evolution of all interest rates. It was the first model to combine the mean-reverting behaviour of the short rate with the log-normal distribution, [1] and is still widely used. [2] [3]
With a fixed-rate product, such as a personal loan or savings account, the interest rate you sign up for is the interest rate you’ll either pay or earn for the life of the product.
Mortgage rates are influenced by the ebbs and flows of the economy, the housing market, as well as the Federal Reserve's decisions on short-term interest rates.
Long-term CDs tend to offer higher interest rates than short-term CDs, but not in the current high interest rate environment. You can use a CD ladder to take advantage of the benefits of short ...
