Resumo

La estimación e interpretación de la estructura a plazo de la tasas de interés es de gran relevancia porque permite realizar pronósticos, es fundamental para la toma de decisiones de política monetaria y fiscal, es esencial en la administración de riesgos y es insumo para la valoración de diferentes activos financieros. Por estas razones, es necesario entender que puede provocar un movimiento en la estructura a plazo. En este trabajo se estiman un modelo afín exponencial de tres factores aplicado a los rendimientos de los títulos en pesos de deuda pública colombianos. Los factores estimados son la tasa corta, la media de largo plazo de la tasa corta y la volatilidad de la tasa corta. La estimación se realiza para el periodo enero 2010 a mayo de 2015 y se realiza un análisis de correlaciones entre los tres factores. Posterior a esto, con los factores estimados se realiza una regresión para identificar la importancia que tiene cada uno de estos en el comportamiento de las tasas de los títulos de deuda pública colombiana para diferentes plazos al vencimiento. Finalmente, se estima la estructura a plazo de las tasas de interés para Colombia y se identifica la relación de los factores estimados con los encontrados por Litterman y Scheinkman [1991] correspondientes al nivel, pendiente y curvatura.

The estimation and interpretation of the interest rates term structures of great relevance because it allows to make predictions, is an important key to policy makers on monetary and fiscal decisions, is essential in risk management and also is an input for the right assessment of many financial assets. For these reasons is necessary to understand what can cause movements in the term structure. These paper estimates a "Three factors exponential affine model" applied to the Colombian sovereign debt yield in pesos. The estimated factors are the short-term rate, it's long term mean and volatility. The data used corresponds to the period between January of 2010 and May of 2015, and also a correlation analysis between the three mentioned factors is performed. Following, with the three factors estimated a regression to identify the importance of each one in the behavior of the Colombian sovereign debt rates for different terms to maturity is performed. Finally, the term structure for the Colombian interest rates is estimated and the relation between the three factors with those founded by Litterman and Scheinkman [1991] corresponding to the level, slope and curvature is identified.
