By Brazil Stock Guide – São Paulo, Aug. 19, 2025 – Brazil’s benchmark stock index fell sharply on Tuesday after a Supreme Court development rattled sentiment toward financials, pushing bank shares among the session’s biggest drags.
The Ibovespa (^BVSP) closed down 2.2% at 134,294.76, after touching an intraday low of 133,996.87 and a high of 137,321.13. Trading volume totaled 20.7 billion reais before final adjustments.
The move followed remarks from Supreme Court Justice Flávio Dino asserting that foreign laws and rulings do not apply to Brazilians on Brazilian soil, a statement that sparked fresh noise for the sector. This article draws on reporting from Reuters (Paula Arend Laier, Reuters Connect).
Among individual names, bioenergy group Raízen (RAIZ4.SA) tumbled again, adding to the day’s bearish tone. Financials were cited as the principal pressure on the index, with investors reassessing legal and regulatory risk after Dino’s comments.
