In 2025 Brazil's declared crypto market hit its highest level ever — about R$506bn in buy-and-sell across all channels — based exclusively on Receita Federal open data (Aug/2019 to Dec/2025), a dataset few countries publish. The defining shift is the rise of the digital dollar: stablecoins reached 80.2% of volume, with Tether (USDT) alone at 89.7% of all stablecoins. A retail base of 4.6 million monthly filers, a growing flight from domestic exchanges, and the new DeCripto reporting rule (in force July 1, 2026) complete the picture.
The rise of the digital dollar
The stablecoin share of Brazilian crypto volume jumped from 3.5% in 2019 to a peak of 91.5% in 2023. Bitcoin's 2024 rally briefly pushed it down to 75.7%, but in 2025 it climbed back to 80.2% — confirming 2024 was an exception, not an inflection. Bitcoin, 80.8% of the market in 2019, shrank to 10.6% in 2025. Within stablecoins the concentration is even sharper: USDT is 89.7% of the segment and R$326.9bn of 2025 volume on its own.
A retail base that exploded
The number of individual filers grew 34-fold in six years — from 134k per month in 2019 to about 4.6 million in 2025. The turning point was 2023, when domestic exchanges began reporting with no value threshold. At the same time, volume is migrating offshore: 36% of 2025 volume happens outside Brazilian brokers, and the 'no-exchange' channel alone is 20.8% of the total. These vectors explain the urgency of the DeCripto rule, whose monthly reporting takes effect on July 1, 2026.

- A massive retail base: 4.6 million individuals filing per month, versus 134k in 2019 — a 34× jump in six years.
- Flight from domestic exchanges: 36% of volume happens outside Brazilian brokers; the 'no-exchange' channel alone is 20.8% of the total.
