Advanced Fixed Income Modeling


Trinomial Interest Rate Model is the building block for valuating fixed income and fixed income derivative products, for example, caps, callable bonds and options on bonds. A trinomial interest rate model is illustrated as follows:

8%
7% (0.167, 0.666, 0.167) 7%
6% (0.25, 0.50, 0.25) 6% (0.167, 0.666, 0.167) 6%
5% (0.333, 0.334, 0.333) 5% (0.25, 0.50, 0.25) 5% (0.167, 0.666, 0.167) 5%
4% (0.25, 0.50, 0.25) 4% (0.167, 0.666, 0.167) 4%
3% (0.167, 0.666, 0.167) 3%
2%

(The blue numbers are interest rate. The green numbers in parentheses are probabilities that the interest rate moves up, the same and down).

You can build your own trinomial interest rate model for your yield curve. Simply fill out the form below:

Term Structure of Interest Rate
Years to Maturity Annual Yield
6 Months %
1 year %
2 years %
3 years %
4 years %
5 years %
 

After you submit the form above, the trinomial model for this term structure will be returned. If you need other more sophisticated models, please contact us by email.
