6. Conclusion
This paper proposes that future values of yields at different maturities be forecast by means of a FAVAR model for the level, slope and curvature of the yield curve. In particular, we estimate an augmented VAR model for a system that includes not only the Nelson–Siegel factors of the Brazilian yield curve, but also the principal components of a large number of macroeconomic and financial indicators. We show that our forecasting approach outperformsthe extant models in the literature, including the random walk benchmark, even at shorter horizons. Further analysis reveals that the use of forward-looking state variables is vital for producing better forecasts.
