Resumo

Este trabalho analisa a manutenção de reservas ótimas precaucionais no país. As distintas medidas de adequação e as simulações produzidas oferecem a mesma inferência sobre a inadequação dos estoques de reservas brasileiras, mantidos em níveis aparentemente excessivos a partir de 2008. O exercício econométrico modelo de correção de erros vetorial (VEC) também não provê muito suporte à afirmação de que acumular níveis altos de reservas seja fortemente significante na determinação do risco-soberano e dos custos de financiamento externo da economia, inclusive não reduzindo a volatilidade da taxa de câmbio. Por sua vez, identificam-se custos fiscais não negligenciáveis derivados da política de esterilização

Abstract

This paper analyses the maintenance of precautionary reserve holdings in Brazil, investigating three interrelated issues. Using one optimization process, an econometric model of the expected effects of this strategy, and on a cost-benefit analysis, the optimal level for international reserves is estimated. Different adequacy measures and model-based simulations offer the same inference about the inadequacy of the Brazilian reserve holdings, which have been maintained at excessive levels since 2008. Furthermore, the econometric exercise does not provide much support for the claim that accumulating high levels of reserves is highly significant in determining sovereign risk and the nation’s external funding costs, as well as showing that reserves do not reduce exchange rate volatility. It seems, otherwise, to be related to a huge fiscal cost associated with the sterilization policy.

Keywords: Foreign reserves. External shocks. Brazilian economy.
