Brazilian equities lose R$734bn in single day, erasing 75.5% of 2026 gains

A 12.9% drop in the market value of Brazilian listed companies on B3 wiped out R$734 billion in one day, nearly equivalent to Petrobras' market cap, and erased 75.5% of gains accumulated in 2026, per Elos Ayta. The scale of the single-day loss suggests a systemic shock, possibly a domestic political or external financial crisis, though the trigger is not specified. This marks a sharp reversal from prior gains and signals heightened market stress in Brazil.
