The Brazilian currency exchange swaps contracts （USS/Brazilian Reais） are submitted to a delta-normal VaR method, in order to evaluate the market risk of each swaps series, by modeling the variance of the daily returns, from August 1999 to January 2003. All daily returns series exhibited heteroscedasticity in the conditional variance and sudden changes in the unconditional variance. The points of changes of the unconditional variance were determined through the Iterative Cumulative Sum of Squares （ICSS） algorithm, and the conditional variance was modeled with Markov-Switching-Generalized Autoregressive Conditional Heteroscedasticity （SWGARCH） in order to capture heteroscedasticity and regime change. The results lead to two main conclusions： First, a VaR model must incorporate heteroscedasticity and regime switching in order to describe the variance of the tested series, submitted to brisk changes of economic and political scenarios. Second, a volatility-based VaR do not necessarily generate forward-looking indicators, but rather coincident indicators of possible financial vulnerabilities. The future research will evolve towards evaluating the effects of the Basel III recommendations as if they could be applied to this crisis period.展开更多

A Brazilian conjuncture analysis starts with the economic stabilization plan known as Piano Real （July, 1994） and takes account that, from 2007 onwards, the world economy is going through troubled times unchained by the international financial crisis that motivated the recent Basel Agreement （Basel III）. There are two lines of analysis： macroeconomic and marketing. From the macroeconomic approach, there are plenty models to predict money supply and monetary aggregates. From a marketing perspective, it can be inferred that technologies potentially innovatives may alter the current scenario. The financial time series chosen are： daily money supply, banking reserves, and annual inflation （monthly announced）. The first statistical and empirical evidences from the period （July, 1994 to December, 2011） show that the management of banking reserves does not interfere with the continuous growth of the monetary base plus demand deposits （M1） and cash in circulation, which possibly indicates an increasing financial inclusion. Moreover, there is no evidence that it creates inflationary pressures. The future works may require competencies pertinent to prospective finance and consumer behavior （marketing）.展开更多
