Brazil is leading Latin America's fintech powerhouse, with a market valued at $5.5 billion in 2025 and projected to reach $19.1 billion by 2034. The Central Bank’s instant payment system, Pix, has been instrumental in transforming Brazilian finance, processing 79.8 billion transactions annually, and potentially displacing credit cards. The White House targeted Brazil over Pix in 2026, claiming it was a barrier to US payment companies. The next step is Pix by Proximity, a tap-to-pay system that could replace credit cards for everyday transactions. Brazil's Open Finance framework, mandated by the Central Bank, has completed all four implementation phases and is now the world's most comprehensive open banking system. The country's crypto framework took effect in February 2026.
