The Ibovespa finished slightly lower at 141,710 on Tuesday as investors awaited upcoming US inflation data, with markets largely expecting at least a 25-basis-point rate cut. On the domestic front, the Supreme Court resumed the trial of former President Jair Bolsonaro over an alleged coup attempt, adding to political uncertainty. Vale shares gained fell 0.3% amid expectations that Chinese steel furnaces will boost capacity, supporting the iron ore outlook, while Petrobras rose 0.8% as Israeli strikes in Qatar pushed crude oil prices higher. In contrast, banks mostly fell on concerns that a guilty verdict for Bolsonaro could prompt the US to sanction certain accounts of Brazilian judges and politicians.
