Brazilian stocks faced a severe sell-off on Monday, 26 October 2026, after President Luiz Inácio Lula da Silva's surprise re-election sent a Japan-listed exchange-traded fund (ETF) plunging approximately 15%, raising fears of further losses when Brazil's domestic markets reopened.
The market turmoil followed Lula's unexpected victory over right-wing Senator Flávio Bolsonaro in Sunday's presidential run-off, reversing investors' expectations of a political shift towards tighter government spending.
