Resumo

O objetivo fundamental dos bancos centrais é o controle da inflação. Para tanto, o principal instrumento de política monetária utilizado é a determinação da taxa básica de juros - denominada de Selic no Brasil. Em 2 de fevereiro de 2022, o governo eleva a taxa Selic com o objetivo de reduzir a inflação. Assim, este estudo tem por objetivo verificar se o anúncio do aumento da Selic impacta negativamente o retorno das ações, calculado a partir da variação do seu preço. Isso ocorre por meio de um estudo de evento, cuja amostra final é composta por 38 ações. Como resultado, verifica-se que mais de 80% dos CARs são negativos e estatisticamente significantes. Logo, é possível confirmar a H1 deste estudo - O anúncio do aumento da Selic impacta negativamente o retorno das ações. Este estudo contribui para a melhor compreensão dos mecanismos de transmissão de política monetária no Brasil
