On December 12, 2024, the Ibovespa index of the Brazilian stock market experienced a significant decline, closing at 126,042 points, marking a decrease of 2.74%. This drop is attributed to a correction of excesses and rising interest rates set by the Central Bank of Brazil (Copom). Analysts noted that this was the worst single-day decline for the Ibovespa in nearly two years, reflecting broader uncertainties in the fiscal landscape. The following day, December 13, the index continued its downward trend, closing at 124,582 points, resulting in a weekly decline of 1.06%. The market's performance is heavily influenced by expectations of higher interest rates and fiscal risks, with notable contributions from major companies such as Vale.
