Foreign Trading Drove Brazil’s Stock Volume in 2025 as Local Institutions Sold

Key Points

• Foreign investors accounted for 62% of B3 cash-equity trading in 2025.
• They traded more than R$ 2.8 trillion ($519 billion) in stocks, up 15% from 2024.
• Net flows were smaller, and Brazilian institutional investors were net sellers.

Foreign investors dominated Brazil’s equity trading in 2025. B3 said non-resident investors traded more than R$ 2.8 trillion ($519 billion) in shares on the cash market last year, a 15% increase from 2024.

The busiest months were May at R$ 263 billion ($49 billion), April at R$ 257 billion ($48 billion), and December at R$ 255 billion ($47 billion). Foreigners represented 62% of cash-market stock trading.

Including BDRs, ETFs, and real-estate funds, foreign cash-market turnover exceeded R$ 3.5 trillion ($648 billion). Turnover is activity, not “new money.” A B3 flow tally for 2025 shows foreigners ended as net buyers of about R$ 25.52 billion ($4.73 billion).

Brazilian institutional investors were net sellers of roughly R$ 46.605 billion ($8.63 billion). Retail was net +R$ 7.029 billion ($1.30 billion). Financial institutions were net +R$ 5.473 billion ($1.01 billion). Other investors were net +R$ 8.583 billion ($1.59 billion).

Foreign flows dominate Brazil liquidity

Foreign trading clustered in the biggest names. Vale led turnover at R$ 197.7 billion ($36.6 billion), followed by Petrobras preferred shares at R$ 154.0 billion ($28.5 billion) and Itaú Unibanco at R$ 130.6 billion ($24.2 billion).

Then came Banco do Brasil at R$ 89.0 billion ($16.5 billion), B3 at R$ 87.6 billion ($16.2 billion), Bradesco at R$ 83.0 billion ($15.4 billion), Ambev at R$ 77.0 billion ($14.3 billion), Petrobras common at R$ 65.2 billion ($12.1 billion), WEG at R$ 65.1 billion ($12.1 billion), and Sabesp at R$ 64.0 billion ($11.9 billion).

Exchange comparisons underline Brazil’s liquidity. In October 2025, B3’s share-trading value was about $93.7 billion, versus Mexico at about $11.9 billion, Chile at about $5.1 billion, and Colombia at about $0.9 billion.

The same snapshot put B3 above India’s BSE at about $16.9 billion and Malaysia at about $14.2 billion. The takeaway is simple: foreigners can dominate price-setting, while domestic long-term money can step back, widening swings.
