RESUMO

The Expectation Hypothesis is tested on the Brazilian term-structure of interest rates, in order to verify whether the slope of the yield curve, wich is represented by the spread between short and long terms interest rates, can explain short term interest rates variations. A monthly average time series of one, three and six months interest rates were used in a single equation regression model. The results suggest that the EH can not be rejected, mostly after the Inflation Target Regime adoption, when interest rates showed lower volatility. Yet, it can be observed that strictly short term rates proved to have greater predictive ability.
