Summary: | This article approaches several different methodologies for calculation of the RAROC (Risk Adjusted Return on Capital) for Brazilian banks. Two questions gave reason to the study: whether the application of different methods for calculation of the RAROC would generate significantly different results?, and checking what is the connection between the RAROC and the generation of economic value, measured by the EVA (Economic Value Added), for the largest banks with operations in Brazil? The following methodologies for verification of the RAROC were applied: Buch’s Method (2011); Prokopczuk’s Method (2006); Prokopczuk’s Method (2006) with application of the VaR technique; Saunders’s Method (2007); Chapelle’s Method (2008); and the Smithon & Hayt Method (2001), by applying these parametric and non-parametric statistics in order to check the sensibility of the differences between models. This study has evidenced that, when we compare the methodology based on minimum capital with other methodologies, there are no significant differences, except in the few cases indicated. It is important to notice it only occurred in the case of the Bank of Brazil and it was concentrated in the comparison of the Creditmetrics models and in the methodology in which there is equivalence by the reference equity.
El presente artículo se ocupa de diferentes metodologías para el cálculo de RAROC (Rentabilidad Ajustada al Riesgo) para los bancos brasileños. Dos preguntas motivaron el estudio: ¿la aplicación de diferentes métodos para el cálculo del RAROC produciría resultados significativamente diferentes?, y ¿cómo se da la relación entre la RAROC y la generación de valor económico, medido por EVA (Valor Económico Agregado) de los mayores bancos que operan en Brasil? Se aplicaron los siguientes métodos de cálculo RAROC: Modelo Buch (2011); Modelo Prokopczuk (2006); Modelo Prokopczuk (2006), utilizando el VaR; Modelo Saunders (2007); Modelo Chapelle (2008); y modelo Smithon y Hayt (2001), la aplicación de sensibilidad paramétrica y no paramétrica para verificar las diferencias entre los modelos de pruebas estadísticas. Este estudio demostró que en la comparación de la metodología basada en el capital mínimo con otras metodologías, no hay diferencias significativas, excepto en los pocos casos mencionados. Es importante darse cuenta de que esto era sólo para el Banco de Brasil y se centró en la comparación de modelos Creditmetrics y metodología en donde existe la equivalencia entre el patri |
