This work presents a first approximation for implementing the Hull and White (1990) and the Black and Karasinski (1991) One-Factor Interest Rate Models in the Colombian market. Both models fit exactly the Colombian term structure of interest rates. Nevertheless, due to the unavailability of interest rate derivatives in our market, implicit calibration was not possible. This process was replaced by the estimation of the volatility using an EGARCH model for the Interbank Interest Rate. This approach will hand out with the pricing of interest rate derivatives in the Colombian Market, mainly, in its early steps of development.
