THE EXECUTIVE VIEW

Pix changed how Brazil pays. What will Open Finance change next?

Brazil’s Open Finance story concerns the ability to use a financial history across institutions and obtain more useful services. Pix provides the adoption case through which this report examines the wider opportunity. By October 2021, 104.4 million people had sent or received Pix. By May 2025, that cumulative count reached 167.5 million. Beyond Pix examines why adoption spread, what economic research shows and whether Brazil is ready to turn Open Finance capability into consistent customer benefit.

What you’ll take away

First-year adoption and dated growth comparisons, with source notes
Charts on payment habits, age differences and platform work
Economic research on wages, deposits and credit, with its limitations
A five-journey readiness assessment and practical lessons for the UK

Based on public regulator and government sources, with official findings and CTRLALTX interpretation distinguished throughout. Research cutoff: 24 October 2026.

THREE CONNECTIONS WORTH MAKING

104.4 million people in the first year.

The October 2021 cumulative count reached 167.5 million by May 2025: 60.4% higher. The report distinguishes that reach from regular usage.

Adoption changed everyday payment behaviour.

BCB surveys show Pix use rising from 46.1% in 2021 to 76.4% in 2024. Charts examine the change and the age differences behind the average.

The next test is customer benefit.

Research on wages and financial deepening helps frame the opportunity. Irregular-income lending, trust and separate data permissions reveal what still needs to be tested.
