Brazil Bars Stablecoins From Bulk Cross-Border Settlement as 1.13 Trillion Reais Market Gets New Rules

Brazil’s central bank will bar virtual assets — including stablecoins — from one specific type of international payment settlement starting October 1, closing a loophole that let currency providers route bulk cross-border flows through crypto while staying outside the formal foreign-exchange system. The move targets a settlement channel that carried a meaningful share of a market worth 1.13 trillion Brazilian reais in declared transactions over six years.

The Hook: Resolution 561 Takes Aim at One Settlement Leg

Resolution 561, published by the Banco Central do Brasil, does not ban stablecoins. What it bans is far more specific: starting October 1, the settlement leg between regulated foreign-exchange providers and their overseas counterparties can no longer run on virtual assets. That leg must instead go through a licensed FX transaction or a qualifying non-resident real account, according to CryptoSlate’s review of the rule.

For everyday users, nothing changes — individual international transfers using virtual assets remain permitted under Brazil’s existing reporting framework. What disappears is the corporate shortcut: electronic foreign-exchange providers bundling thousands of small payments together, netting the balances across a day, and then settling the difference with a foreign counterparty in stablecoins instead of through the banking system.

The Numbers Behind the Decision

The scale of stablecoin activity in Brazil explains why the central bank wanted visibility. According to the country’s tax authority, Brazilians declared 1.13 trillion reais in stablecoin transactions between August 2019 and December 2025 — roughly 72 percent of all declared crypto activity in that window. The concentration has only grown: stablecoins accounted for close to 80 percent of declared crypto volume in 2025 alone, and Tether’s USDT made up nearly 89 percent of that stablecoin total.

• 1.13 trillion reais — declared stablecoin transactions in Brazil, August 2019 to December 2025.
• ~72 percent — stablecoin share of all declared crypto activity in that period.
• ~80 percent — stablecoin share of declared crypto volume in 2025.
• ~89 percent — USDT’s share of Brazilian stablecoin volume.

The Core Conflict: Cost Savings vs. Regulatory Sightlines

Oscar Guillermo Farah Osorio, founding partner at Brazilian law firm Zanella & Farah, told CryptoSlate the rule resolves genuine ambiguity. Brazil’s 2022 virtual assets law gave the central bank authority to decide which crypto operations count as foreign-exchange activity, but detailed rules never followed — leaving a gap that some market participants used to their advantage. The eFX model suits high-volume, low-value flows like streaming subscriptions, online gaming and e-commerce particularly well, because thousands of payments can be netted into a single settlement.

The cost math behind the loophole is straightforward. Settling in stablecoins let providers dodge Brazil’s financial transaction tax on conventional FX conversions, along with correspondent-bank and SWIFT-network fees. Farah expects those real costs to eventually land on Brazilian consumers and businesses now that the shortcut is gone. Providers can still net and consolidate balances — they just have to settle through permitted channels.

Notably, independent research has questioned how big the savings actually were. A July study by the Bank of Italy tested 200-USD USDC transfers across ten international corridors, including Brazil, and found total costs ranging from 0.3 percent to nearly 9 percent, with no consistent advantage over conventional channels. The blockchain transfer itself accounted for only a marginal share of the cost — currency conversion and local payment infrastructure drove most of it. The Financial Stability Board reached a similar conclusion in July, suggesting stablecoins’ near-term value may sit inside hybrid arrangements built around existing bank money rather than as standalone global rails.

Market Implications: Brazil Tightens as the Sector Restructures

The resolution lands amid a broader regulatory squeeze in Brazil. Fewer than 10 percent of the country’s crypto firms are expected to seek licenses as an October deadline nears, and fintech Lemon announced this week it is exiting Brazil entirely over what it called disproportionate licensing costs. Resolution 561 adds a second, quieter message: Brazil is not hostile to stablecoins, but it insists they operate where regulators can see them.

Cregis CEO Shawn Yan told CryptoSlate the more consequential shift is happening inside brokers’ own infrastructure — treasury management, liquidity movement between entities and internal settlement, all invisible to end clients. As volumes grow, he argued, the question becomes how much of that infrastructure a broker wants to control directly. The core business is still foreign exchange; what is changing is the plumbing underneath it.

The Verdict

Brazil’s approach is becoming a template other emerging markets may copy: allow individual crypto transfers, license the exchanges, but refuse to let stablecoins replace the formal settlement layer for commercial cross-border flows. For holders of USDT and USDC, nothing about Resolution 561 touches personal wallets or transfers. For the payments industry, it is a reminder that the era of regulatory arbitrage in cross-border stablecoin settlement is closing — one resolution at a time. Bitcoin was trading near 81,454 USD on Saturday, with Ethereum around 2,640 USD, as markets digest a week of regulatory moves spanning Washington, Brussels and now São Paulo.
