Brazil's Central Bank Bans Crypto from Cross-Border eFX Flows in Resolution 561

Brazil's Banco Central do Brasil (BCB) published Resolution BCB No. 561 on April 30, 2026, barring all virtual assets, including USDT, USDC, and Bitcoin, from being used as settlement instruments within the country's regulated eFX (electronic foreign exchange) system. The rule takes effect October 1, 2026, giving affected fintechs and payment firms roughly five months to migrate off stablecoin-based cross-border payment rails and onto traditional FX channels. [1][2]

What the Rule Actually Prohibits

Resolution 561 amends the earlier Resolution BCB No. 277 of 2022 and draws a precise line around the eFX framework, Brazil's regulatory structure for digital international payments, remittances, cross-border purchases, and withdrawals. Under the new text, the settlement leg between an eFX provider and its foreign counterparty must occur through a traditional foreign exchange transaction or through movements in a non-resident Brazilian real-denominated account held in Brazil. The resolution states explicitly that virtual assets are prohibited as a settlement option in this context. [1][3]

In practice, a remittance company operating under eFX can no longer accept reais from a Brazilian customer, convert those funds into USDT or USDC, and settle the transfer abroad via blockchain. That workflow had become standard for several major cross-border payment providers because it is faster and materially cheaper than correspondent banking. Wise, Nomad, and Braza Bank are among the firms most directly affected. Nomad had built its settlement flow around Ripple's network, converting to stablecoins for the foreign leg of transfers between Brazil and the United States. Braza Bank went further, issuing a real-backed stablecoin on the XRP Ledger to support its cross-border book. [1][2]

The regulation is carefully scoped. It does not prohibit individual Brazilians from buying, selling, holding, or transferring crypto assets. Exchanges and virtual asset service providers operating under Resolution BCB No. 521, which entered force on February 2, 2026, continue under that separate framework and are not affected by the eFX restriction. As Lucas Cury, head of Global Payments and Remittance at Mercado Bitcoin, put it, the BCB is "separating two regulatory tracks: eFX, which must now settle exclusively through traditional FX or non-resident real accounts, and crypto-remittance, which continues to operate under Resolution 521." [3]

Scale of the Market Being Targeted

The BCB's intervention targets a large and fast-growing segment. Brazil is Latin America's largest crypto market by on-chain volume and ranks fifth globally in crypto adoption according to TRM Labs. Monthly crypto transaction volumes have reached between $6 billion and $8 billion, with stablecoins representing as much as 90% of that activity, a figure BCB Governor Gabriel Galipolo cited at a Bank for International Settlements conference in Mexico City in February 2025. [4][5]

In Q1 2026, the BCB reported $6.9 billion in overseas crypto purchases by Brazilians, more than double the figure recorded in Q1 2025. Of that total, stablecoins accounted for approximately 98%, or $6.8 billion. [5]

The central bank's concern is not the existence of stablecoins but their function as invisible settlement infrastructure. When a Brazilian sends money abroad through an eFX provider using USDT on TRON, that transaction is effectively invisible to BCB oversight, sits outside the Brazilian financial system, and avoids the reporting requirements imposed on traditional FX flows. Galipolo has described the pattern as raising concerns about tax compliance and anti-money laundering controls. [4]

"The widespread use of stablecoins brings regulatory and supervisory challenges, especially in taxation and anti-money laundering areas."

Compliance Timeline and New Requirements

Resolution 561 establishes several parallel deadlines. Authorized eFX institutions must update their registration in the BCB's Unicad system by October 30, 2026. Firms currently operating eFX services without BCB authorization may continue temporarily, but must apply for formal approval by May 31, 2027. All eFX providers, authorized or in the transitional period, must use segregated accounts exclusively for client funds, file detailed monthly reports with the BCB, and comply with enhanced know-your-customer procedures. Mandatory data retention extends to ten years. [2][3]

The resolution also expands the scope of permitted eFX activities in one direction: providers can now facilitate transfers linked to financial and capital market investments in Brazil or abroad, subject to a per-transaction cap of $10,000. The same cap applies to digital payment solutions not connected to e-commerce platforms. This reflects the BCB's stated objective of broadening legitimate access to eFX while simultaneously tightening its settlement architecture. [1]

LATAM Regulatory Context

Brazil's move arrives as the wider LATAM region is crystallizing divergent regulatory approaches to stablecoins. Latin America recorded over $730 billion in crypto volume in 2025, a 60% year-on-year surge, with stablecoin transactions accounting for $324 billion of that total. Brazil alone receives roughly one-third of all LATAM crypto volume. [6]

Mexico, home to $62 billion in annual remittances and where Bitso processes approximately 10% of US-Mexico corridor transfers via crypto, operates under the 2018 Fintech Law. That law permits virtual asset operations through licensed institutions but has seen Banco de Mexico restrict banks from offering crypto directly to retail clients. Argentina, which experienced annual inflation exceeding 200% in recent years, has allowed stablecoin adoption to surge as a dollar hedge under a lighter registration regime. Neither country has moved to restrict eFX-style stablecoin settlement in the way Brazil has now done. [6]

The BCB has been building toward this point incrementally. Resolutions BCB 519, 520, and 521, published in November 2025 and effective February 2026, created the licensing framework for all virtual asset service providers. The Travel Rule for domestic VASP transfers took effect in February 2026. Resolution 561 is the next layer, drawing the boundary between the licensed VASP world and the separately regulated eFX channel. [3]

Industry associations representing more than 850 companies already pushed back in March 2026 against a separate proposal to extend Brazil's IOF financial transaction tax to stablecoin operations. The eFX ban adds a second compliance front for firms that had positioned Brazil as the gateway to broader LATAM stablecoin payment expansion.
