Análise da curva de cupom cambial brasileirauma aplicação da análise de componentes principais com enfâse em sua utilização para imunização de carteiras

Resumo

In this dissertation it was presented, for the first time in the Brazilian market, an application of the principal components analysis for the identification of the factors that influence the behavior of the term structure of onshore Brazilian dollardenominated interest rates, having as sample quotations of onshore Brazilian dollardenominated interest rates derivatives (BM&F contracts of DDI and FRA - Forward Rate Agreement), spot quotations of R$/US$ exchange rates and selling quotations of Ptax800, for the period between 02/01/2002 and 29/12/2005. Through the application of the technique of principal components analysis for the spot and forward curves of onshore Brazilian dollar-denominated interest rates, it was possible to observe superiority in the explanation power of the latter when compared to the former, with three principal components being responsible for more than 94% of the variability explained in the application of the principal component analysis for the forward curve. The superiority of the results obtained in the principal components analysis of the forward curve of onshore Brazilian dollar-denominated interest rates could also be observed in the visual interpretation of the components of level, slope and curvature (interpretation which could not be clearly obtained by the analysis of the graphs related to the spot curve). This work also had as an objective the analysis of the effectiveness of an application of immunization of the risk of variation in the onshore Brazilian dollar-denominated interest rates, based on the results previously obtained by the principal components analysis of the forward curve of onshore Brazilian dollar-denominated interest rates. The immunization performed demonstrated high effectiveness in the comparison between the results of the immunization object (arbitrary portfolio of DÛlarxCDI swaps) and the results of the immunization instrument (BM&F future contracts of forward onshore Brazilian dollar-denominated interest rates). This result is of great importance for the management of portfolios that contain exposure to the risk of variations in the onshore Brazilian dollar-denominated interest rates.
