B3 August ADTV jumps 34% to R$30.3bn; banks flag September volatility

B3's average daily trading volume rose 34% month-on-month in August to R$30.3 billion, signaling a recovery in Brazilian equity market activity. Banks, however, are bracing for increased volatility in September, likely tied to domestic political or external macro risks. The volume rebound supports B3's near-term revenue outlook, but the anticipated volatility could dampen sustained growth.
