Abstract

Utilizando dados financeiros brasileiros da BM&F, testa-se a validade do modelo de valor presente na estrutura a termo de juros, também conhecido na literatura como Hipótese das Expectativas. Estes modelos relacionam a taxa de juros de longo prazo à uma média das taxas de juros de curto-prazo mais um prêmio de risco, invariante no tempo. Associada a estes modelos está a questão da previsibilidade dos retornos de ativos financeiros ou, mais especificamente, à previsibilidade na evolução das taxas de juros. Neste artigo é realizada uma análise multivariada num arcabouço de séries temporais utilizando a técnica de Auto-Regressão Vetorial. Os resultados empíricos aceitam apenas parcialmente a Hipótese das Expectativas para a estrutura a termo de juros brasileira.
