As a natural extension to León and Vivas (2010) and León and Reveiz (2010) this paper briefly describes the Cholesky method for simulating Geometric Brownian Motion processes with long-term dependence, also referred as Fractional Geometric Brownian Motion (FBM). Results show that this method...

The most recent financial crisis unveiled that liquidity risk is far more important and intricate than regulation have conceived. The shift from bank-based to market-based financial systems and from Deferred Net Systems to liquidity-demanding Real-Time Gross Settlement of payments explains some...

Las opciones no solo son instrumentos que ofrecen la oportunidad de cubrir o aprovechar cambios direccionales en el precio del activo subyacente, sino que permiten valorar la volatilidad de este. En mercados desarrollados es posible identificar que los agentes sobrevaloran o subvaloran la...

This paper presents a methodology to estimate the intraday liquidity that systemically important entities (SIE) need to fulfill all its obligations in a timely fashion, when a simulated failure-to-pay from its main liquidity supplier by discretionary concepts of payment occurs. Using the Bank of...

En este artículo se propone un método numérico para la calibración de un modelode equilibrio general dinámico y estocástico (DSGE). Esencialmente, éste consisteen utilizar un algoritmo híbrido de optimización, primero para encontrar un estadoestacionario del modelo, y luego para...

Defining whether a financial institution is systemically important (or not) is challenging due to (i) the inevitability of combining complex importance criteria such as institutions´ size, connectedness and substitutability; (ii) the ambiguity of what an appropriate threshold for those criteria...

Este documento estudia la estabilidad del sistema de pagos (SP) de alto valor en Colombia (CUD) ante el incumplimiento de una entidad sistémicamente importante, y evalúa la capacidad de respuesta de las entidades afectadas a partir de la utilización de sus recursos y a través de los...

Operational Risk (OR) results from endogenous and exogenous risk factors, as diverse and complex to assess as human resources and technology, which may not be properly measured using traditional quantitative approaches. Engineering has faced the same challenges when designing practical solutions...

This document presents an enhanced and condensed version of preceding proposals for identifying systemically important financial institutions in Colombia. Three systemic importance metrics are implemented: (i) money market net exposures network hub centrality; (ii) large-value payment system...

The most recent episode of market turmoil exposed the limitations resulting from the traditional focus on too-big-to-fail institutions within an increasingly systemic-crisis-prone financial system, and encouraged the appearance of the too-connected-to-fail (TCTF) concept. The TCTF concept...
