This article aims to investigate the relationship between the term
structure of interest rates and macroeconomic factors in selected countries
of Latin America, such as Brazil, Chile and Mexico, between 2006 and 2014,
on an autoregressive vector model. Specifically, we perform estimations of
Nelson-Siegel, Diabold-Li and principal component analysis to test how the
change of macroeconomic factors, e.g. inflation, production and unemployment
levels affect the yield curves. For Brazil and Mexico, GDP and inflation
variables are relevant to change the yield curves, with the former shifting
more the level, and the latter with greater influence on the slope. For
Chile, inflation had the greatest impact on the level and, specifically for
Mexico, the unemployment variable also changed the slope of the yield
curve.
