Abstract

Este texto expone una metodología para calcular las probabilidades de default de diversos agentes a partir de la información disponible en el mercado. Utilizando las tasas de riesgo como una aproximación útil para extraer las probabilidades de supervivencia de los spreads observados, a través del modelo JPMorgan. Además, se derivan fórmulas cerradas para las tasas de riesgo promedio. Luego, se prueba el modelo con datos actuales y se estima la diferencia versus los resultados propuestos por el proveedor de información Bloomberg. Finalmente, se utilizan los resultados obtenidos para calcular el ajuste por riesgo de default unilateral de las partes en un contrato con un flujo de efectivo único. This text presents a methodology to calculate the probabilities of predetermined agents from the information available in the market. Using the risk rates as a useful approximation to extract the survival probabilities of the observed spreads, through the JPMorgan model. In addition, closed formulas are derived for average risk rates. The model is then tested with current data and the difference is estimated versus the results proposed by the information provider Bloomberg. Finally, the results obtained are used to calculate the unilateral default risk adjustment of the parties in a contract with a single cash
