I started by doing in interpolation by cubic splines to my rates to get an expression of the instantaneous forward rate (f(0,t)) and thus the short rate (r(0)).

For the Vacisek model, i calibrated the parameters on the bond prices which gave me satisfying results.

As for the H&W model, it follow automatically the current bond prices so I have to calibrate it on either caps or swaptions but i really know which derivates to take (in term ok stiker and maturity).

Could someone be friendly enough to guide me and help me to understand?

Have you asked your manager? Do that first.

Also, this probably should be in the Finance/Investments area. As the person who created the thread, you can move it there. Use Thread Tools, Move or Copy.

Pluto is no longer a planet and I am no longer an actuary. Please take my opinions as non-actuarial.

I should keep these four permanently.
