Resumo
O foco principal do artigo foi analisar as relações dinâmicas entre variáveis macroeconômicas e o índice de mercado do Ibovespa entre 2003 e 2023. Para isso, foi utilizada uma abordagem baseada na Teoria Macroeconômica Neo-Keynesiana e seus mecanismos de transmissão. A metodologia empírica foi baseada em um Vetor Autorregressivo (VAR) a fim de analisar a decomposição da variância do termo de erro e a Função de Resposta ao Impulso referentes ao mercado acionário doméstico.
As variáveis selecionadas para o sistema foram: Preço do barril do petróleo bruto (Brent), EMBI+ Risco-País, Taxa nominal de câmbio, Índice de Atividade Econômica do Banco Central (IBC-Br), Índice Nacional de Preços ao Consumidor Amplo (IPCA), Taxa de juros dos Certificados de Depósitos Interbancários (CDI) e o índice do Ibovespa propriamente dito.
Os resultados encontrados apontam para valores significativos de explicação da variação do Ibovespa para as variáveis de preço do petróleo, risco país, taxa de câmbio e Ibovespa. Além disso, ao analisar a Função de Resposta ao Impulso foi constatada uma reação positiva do índice frente à choques no preço do petróleo e no próprio Ibovespa. Em contrapartida, o índice reagiu negativamente a choques na taxa de câmbio e no risco país. Já para as variáveis de atividade econômica, inflação e taxa de juros não foi possível observar variações relevantes.
The main focus of this article has been to analyze the dynamic relationships between macroeconomic variables and the Ibovespa market index between 2003 and 2023. In order for that, the chosen approach was based on the Neo-Keynesian macroeconomic theory and its transmission mechanisms. The empirical methodology was based on a Vector Autoregressive (VAR) model aiming to analyse the decomposition of the variance of the error term and the Impulse Response Function (IRF) relating to the domestic stock market. The selected variables for the system were: the barrel price of Brent crude oil (Brent), EMBI+ country risk, nominal exchange rate, Central Bank Economic Activity Index (IBC-Br), Extended National Consumer Price Index (IPCA), Interbank Deposit Certificates interest rate (CDI) and the Ibovespa index itself. The results found indicate significant values explaining the variation of the Ibovespa for the variables of the oil price, country risk, exchange rate and Ibovespa. In addition, when analyzing the Impulse Response Function, a positive reaction of the index against shocks in the oil price and in Ibovespa itself was found. Notwithstanding, the index responded negatively to shocks in the exchange rate and country risk. Lastly, it was not possible to observe relevant variations for the variables of economic activity, inflation and interest rate.
