Abstract

O estudo analisa a relacao de causalidade entre o indicador bursátil brasileiro em relacao a outros indicadores de bolsa de valores. Especificamente, o tempo de estudo incorpora a crise mundial causada pela covid-19 e a guerra pelo preco do petróleo. Utilizaram-se as séries diferenciadas, considerando a existencia de raiz unitária; posteriormente, realizou-se a estimacao do modelo VAR e a causalidade de Granger. Nos resultados, verifica-se que a causalidade entre o Ibovespa com o S&P500 e o Nikkei é bidirecional. Esses resultados sao consistentes ao relacionar o grau de intercambio comercial e de origem do investimento estrangeiro no Brasil. ****** En este artículo se analiza la relación causal entre el indicador de bolsa de valores de Brasil con relación a otros indicadores. El tiempo de estudio incorpora la crisis mundial causada por la COVID-19 y la guerra por el precio del petróleo. Se utilizaron series diferenciadas considerando la existencia de una raíz unitaria; luego se estimó la causalidad de Granger a partir de un VAR. Se verifica que la causalidad entre el Ibovespa con el S&P500 y el Nikkei es bidireccional. Estos resultados son consistentes al relacionar el grado de intercambio comercial y el origen de la inversión extranjera en Brasil. ****** This paper analyzes the causal relationship between the Brazilian stock market indicator and other stock exchange indicators. Specifically, the study time incorporates the world crisis caused by the covid-19 and the war over the price of oil. Were used the differentiated series considering the existence of a unit root, the VAR and Granger Causality models were subsequently estimated. The results show that the causality between the Ibovespa with the S&P500 and Nikkei is bidirectional. These results are consistent when relating the degree of commercial exchange and the origin of foreign investment in Brazil.
