Abstract
The development of financial markets relies on the use of reference interest rates. These rates allow parties to negotiate variable rate financial contracts. This article introduces a methodology that allows to find an indicator that approximates the funding cost in colones, which might be used as a reference rate. We create 94 possible indicadors and rank them in terms of how similar they are to the funding cost. We conclude that there is a simple indicator that does well. It is a weighted average of term deposite and overnight account rates. For the term deposite rate we calculate for each maturity a weekly average rate weighted by the amount of each transaction. The indicator is an average of these rates weighted by the proportion that each maturity has represented in the intermediaries funding during the last year. The overnight account rate corresponds to the average cost obtained directly from the intermediaries’ financial statements. ***Resumen: El desarrollo de mercados financieros requiere el uso de tasas de referencia para la negociación de contratos con tasas de interés variables. En este estudio se introduce una metodología que permite encontrar un indicador del costo de captación en moneda nacional de las entidades financieras que podría ser utilizado como tasa de referencia. Con este fin se construye un conjunto de 94 posibles indicadores que se ordenan de acuerdo a qué tan similares son al costo de captación. Se concluye que existe un indicador simple que permite cumplir el objetivo planteado. Este indicador consiste de un promedio ponderado de las tasas de las captaciones a plazo y de los depósitos a la vista. Para las captaciones a plazo se calcula para cada plazo un promedio ponderado por monto de las tasas negociadas durante la última semana, y se obtiene un indicador como el promedio de estas tasas que se pondera por la proporción que cada plazo representa en las captaciones a plazo durante el último año. Para los depósitos a la vista se utiliza como tasa el costo medio de los depósitos que se obtiene de los estados financieros de las entidades.
