Abstract

En este documento proponemos aplicar un algoritmo de agrupamiento para identificar las operaciones relacionadas con la demanda de liquidez dentro del total de operaciones simultáneas realizadas en el Sistema Electrónico de Negociación (SEN) para Colombia. Esta aplicación, la cual es novedosa en este contexto, permite calcular el monto diario transado por liquidez en este sistema y estudiar su precio medio a plazo \textit{overnight}, que denominamos tasa de Liquidez Colateralizada (LICA). Frente a otros indicadores del precio de la liquidez \textit{overnight} disponibles en Colombia como la Tasa Interbancaria (TIB) a un día y el Indicador Bancario de Referencia (IBR) \textit{overnight}, la tasa LICA refleja la dinámica de un mercado con volúmenes diarios más altos, que la alejan de problemas de colusión y manipulación. Además, esta tasa mitiga la inclusión de primas de riesgo de contraparte por las características del sistema en el cual se realizan las operaciones (SEN). Este documento contribuye a la discusión internacional sobre tasas de referencia del mercado monetario más robustas, al seguimiento que debe hacer el Banco Central colombiano para la adecuada implementación de su política monetaria, y, facilita el desarrollo de trabajos posteriores que requieran identificar las operaciones relacionadas con demanda de liquidez o con demanda de títulos en el segmento colateralizado del mercado monetario. *** ABSTRACT: In this paper, we propose the application of a clustering algorithm to identify transactions associated with liquidity demand within the universe of repurchase agreements conducted through Colombia's Electronic Trading System (Sistema Electrónico de Negociación, SEN). This novel application in this context allows us to estimate the daily volume of liquidity-driven transactions in this market and to analyze their average overnight price, which we refer to as the Collateralized Liquidity Rate (LICA, Spanish acronym). Compared with other overnight liquidity price indicators available in Colombia, such as the Interbank Rate (Tasa Interbancaria, TIB) and the overnight Reference Banking Indicator (Indicador Bancario de Referencia, IBR), the LICA rate reflects the dynamics of a market with substantially higher daily trading volumes, making it less susceptible to collusion and manipulation concerns. Moreover, this rate mitigates the inclusion of counterparty risk premia due to the characteristics of the trading platform on which these transactions are conducted (SEN). This paper contributes to the international discussion on more robust money market benchmark rates, supports the monitoring efforts required by the Colombian central bank for the effective implementation of monetary policy, and facilitates future research aimed at identifying transactions associated with liquidity demand or securities demand within the collateralized segment of the money market.
