Brazil: where 90% of digital-asset flow is stablecoins, and the central bank is folding them into the rules rather than fighting them
Brazil is one of the most sophisticated markets in this series, and one of the most instructive. It is Latin America's largest economy, a genuine fintech powerhouse, and a place where stablecoins already dominate digital-asset activity. What makes it interesting is not a ban or a free-for-all, but something more mature: a central bank that has decided to treat stablecoins as a regulated part of the financial system — while drawing a firm line around how they may be used across borders.
For anyone studying how a serious, capable regulator integrates stablecoins into an existing financial system, Brazil is the case study.
Orientation: a fintech leader, not a frontier
Brazil is home to over 210 million people and the largest economy in South America. It is also, crucially, a country that has already modernised its payments system more successfully than most developed nations. Its instant-payments network, Pix, became one of the fastest-adopted payment systems in the world, and the central bank is now building Drex, an infrastructure for tokenising bank deposits and securities. This is not a country waiting for financial innovation. It is one producing it.
Against that backdrop, stablecoin adoption has been enormous. Brazil received an estimated $318 billion in digital-asset value between mid-2024 and mid-2025 — close to a third of all of Latin America's flows. And remarkably, around 90 percent of that volume is in stablecoins, with USDT and USDC the dominant instruments. Brazilians are using dollar stablecoins at vast scale, primarily as a store of value and a settlement tool, not for speculation.
The regulator's approach: integrate, don't prohibit
Here is where Brazil diverges from most of the markets I have covered. Rather than banning stablecoins or leaving them in a grey zone, the Central Bank of Brazil has built a comprehensive framework to bring them inside the regulated system.
Through a set of resolutions taking effect in 2026, the central bank established itself as the regulator of all virtual-asset service providers, with licensing, consumer-protection, anti-money-laundering, and cybersecurity requirements. Most tellingly, because stablecoins account for around 90 percent of the market, the framework treats them as foreign-exchange operations — regulating dollar stablecoins as what they functionally are in Brazil: a way of holding and moving foreign currency. Algorithmic or unbacked stablecoins, those without auditable fiat or government-bond reserves, are prohibited.
This is a regulator that looked at the data, recognised that stablecoins had become a de facto FX instrument for its citizens, and chose to regulate them as such rather than pretend otherwise. It is the most clear-eyed official response in this entire series.
The line Brazil drew
But Brazil also drew a firm boundary, and it is the one that matters most for cross-border work. The central bank banned electronic foreign-exchange providers from using stablecoins or other digital assets to settle overseas remittances. Cross-border flows must now run through regulated foreign-exchange transactions or non-resident local-currency accounts, not through a stablecoin back-end.
In other words: Brazil will let stablecoins function as a regulated FX asset domestically, but it will not allow them to become an unregulated settlement rail for cross-border payments that bypasses the formal FX system. The state wants the cross-border leg inside its supervised framework.
What it means for treasury infrastructure
Brazil teaches the same discipline that Vietnam and Indonesia did, but at a higher level of regulatory sophistication. The opportunity is not to push stablecoin settlement where the central bank has explicitly restricted it. It is to operate within Brazil's regulated framework — recognising that the central bank has created a clear, licensed structure for digital-asset activity, treats stablecoins as FX, and expects cross-border flows to run through supervised channels.
For a compliance-first treasury-infrastructure business, that is actually an attractive environment, not a hostile one. A capable regulator that has defined the rules clearly is far easier to build a durable business around than a market with no rules at all. The work in Brazil is to serve legitimate corporate and cross-border treasury needs through the regulated FX and VASP framework the central bank has built, in a market where stablecoin familiarity is already near-universal.
My read
Brazil is the most encouraging large emerging market in this series, precisely because its regulator is so capable. Pix and Drex prove Brazil can build world-class financial infrastructure, and its stablecoin framework proves it can regulate digital assets with clear eyes rather than fear. The combination of massive existing stablecoin adoption, a sophisticated regulator, and a defined legal framework is exactly the foundation on which a serious, compliant business can be built.
The discipline Brazil demands — respect the FX rules, route cross-border through supervised channels, work inside the framework — is not a constraint I object to. It is the same discipline I have argued for throughout this series. Brazil simply enforces it more competently than most. For an operator who intends to do this properly, that is a feature, not a bug.
