The increase came over 13 trading days and amounted to 10.02%.
It was the fourth-largest monthly increase in cash terms since 2020, when the data series began.
The rise followed the first round of Brazil’s presidential election, as investors reassessed political and economic expectations.
The start of Senator Flávio Bolsonaro’s presidential campaign and foreign investment in the exchange also contributed, according to the analysis.
Foreign investors had a net inflow of about R$10.6 million during the 13 trading days.
October’s gain was recorded before the month ended and stood R$36 billion below the largest increase in the series, set in January 2026.
