On April 30, 2026, the Central Bank of Brazil published in the Official Gazette the BCB Resolution No. 561, signed by the Director of Regulation Gilneu Francisco Astolfi Vivan. The headlines the next day, in crypto and mainstream media, translated the act into variations of the same sentence: "Central Bank prohibits the use of cryptocurrencies in capital transfers abroad". The sentence is, in an approximate sense, true. In technical sense, however, it blurs at least three distinctions that make practical difference for companies, lawyers, compliance officers and users — and that careful reading of the normative, combined with its framing within Brazil's regulatory agenda of 2025-2026, clarifies.
This analysis organizes what Resolution 561 actually does, what it does not do, in what tension it places other recent norms of the Central Bank itself — especially BCB Resolutions 519, 520 and 521, which we covered on April 29 — and what are the practical consequences, in chronological sequence, for actors in the Brazilian international payments and virtual assets market.
What Resolution 561 is, legally
The first technical point worthy of note: Resolution 561 is not an autonomous norm. It is, formally, an amending resolution — it alters BCB Resolution No. 277, of December 31, 2022, which implemented Law No. 14,286/2021 and established, in the dedicated chapter, the regime of the international payment or transfer service, known by the operational acronym eFX.
The eFX, in the definition of art. 49 amended by 561, is "the international payment or transfer service provided in this Title that enables" a set of specific operations: acquisition of goods and services (including via international use card), withdrawals in the country or abroad, and transfer of resources related to investment in the financial and securities market. It is the legal framework under which fintechs, processors, international card issuers, currency exchange brokers and payment institutions authorized by the Central Bank operate today the cross-border movement of Brazilian retail and mid-market.
The central point of 561 is in two articles: art. 50, with new wording, and the set of new articles (50-A, 50-B, 50-C). It is in art. 50 that the phrase that sparked the headlines sits:
"Payment or receipt between the eFX provider and its counterparty abroad must be carried out exclusively: I — through a currency exchange operation or movement in real account of non-resident held in Brazil, being prohibited the use of virtual assets."
The rule is restrictive and exhaustive. The settlement between the Brazilian eFX provider and the foreign counterparty must happen through one of two channels: formal currency exchange operation (which involves dollar, euro, or other fiat currency settled via correspondent banking or similar network), or movement in real account held in Brazil in the name of a non-resident person. Virtual asset — Bitcoin, USDT, USDC, BRZ, any of them — is off the list.
The distinction that matters: crypto as purpose vs. crypto as instrument
Honest reading of 561, however, requires introducing a distinction that many of the initial coverage did not make. The virtual asset is prohibited as a settlement instrument. It is not prohibited as the purpose of the operation.
The proof is in Annex V of Resolution 277/2022, amended by 561. Among the purpose classification codes that eFX providers must report monthly to the Central Bank via the Currency Exchange System (by the 10th of the following month, per new art. 81-A), appears, within the "Acquisition of goods and services" section:
- Code 34038 — virtual assets
The code exists because the operation it describes is permitted. In other words: a Brazilian can use eFX to buy virtual assets from a foreign counterparty — an exchange like Coinbase, Kraken, Binance international, or any other crypto provider based outside the country. What Resolution 561 prohibits is that the settlement between the Brazilian eFX provider and that foreign exchange happens in virtual asset. The foreign exchange must receive USD through traditional currency exchange, or must receive BRL in a non-resident account held in Brazil.
The distinction seems subtle. Operationally, it is decisive. Imagine two concrete structures:
- Structure A — prohibited: Brazilian customer contracts eFX provider to send US$ 9,000 abroad. The provider, instead of operating conventional currency exchange, converts BRL to USDT (or another stablecoin) on the Brazilian side via partner exchange, transfers the USDT to the foreign counterparty via blockchain, and the counterparty receives USDT that it may or may not convert to USD. Settlement between provider and foreign counterparty was in virtual asset. That is what 561 prohibits.
- Structure B — permitted: Brazilian customer contracts eFX provider to buy US$ 9,000 in BTC from a foreign exchange. The provider converts BRL to USD through conventional currency exchange, pays the foreign exchange in USD, the exchange delivers the BTC to the Brazilian customer (or to the wallet he indicates). The purpose of the operation was to acquire virtual asset. The settlement between provider and foreign exchange was in fiat currency. That is what 561 permits — and, more than permit, formally classifies under code 34038.
What changes, in practice, is the business model of fintechs that were building eFX architecture via crypto-rail — using stablecoin as a transparent bridge between BRL and USD to reduce cross-border settlement costs. That model, popularized in 2025-2026 by a wave of B2B products, is exactly what 561 closes. The competing model — using eFX to serve as a gateway for Brazilian customer to foreign crypto products — remains open, now explicitly regulated.
Who can provide eFX as of 561
Art. 49, § 2º, with new wording, brings the exhaustive list of who is authorized to provide the service:
- Banks;
- Caixa Econômica Federal;
- Development agencies;
- Credit, financing and investment companies;
- Securities brokers;
- Securities distributors;
- Currency exchange brokers;
- Payment institutions authorized to function by the Central Bank as electronic money issuer, post-paid payment instrument issuer, or acquirer.
Important: the list is independent of authorization to operate in the currency exchange market. That is, a payment institution authorized as electronic money issuer can provide eFX even if it is not itself authorized to operate currency exchange — as long as the settlement counterparty is an institution that operates currency exchange. The eFX, in that sense, operates as an orchestration layer.
Art. 49, § 3º, maintains the obligation to include the modality in Unicad — Information System on Entities of Interest to the Central Bank with five business days before the beginning of the provision. Institutions already authorized and already providing eFX today have until October 30, 2026 (art. 56-A) to formally include the modality in Unicad.
What happens with eFX providers today operating irregularly
Here enters one of the most consequential elements of the normative. Art. 56-B is directed to a specific universe: legal entities that today provide eFX without being framed in the list of art. 49, § 2º. That universe includes, in practice, fintechs that operate international remittance services, e-commerce platforms with embedded international payment solution, non-bank international card processors, and correlates — a relevant population, especially among Series A and Series B fintechs in the Brazilian payments market.
These legal entities have two paths:
- Request authorization from the Central Bank by May 31, 2027 to function as a payment institution in the modality electronic money issuer, post-paid payment instrument issuer, or acquirer. While authorization is not granted, they can continue providing eFX, but with material restrictions.
- Cease the provision of eFX in 30 days from the deadline (if they have not submitted a request) or from notification of denial (if they submitted and the request was denied in final decision).
The material restrictions during the authorization phase (art. 56-B, § 2º) are harsh. The legal entity in transition can only perform payment or receipt by currency exchange operation or movement of third-party interest in real account of non-resident held in Brazil. Prohibited the use of virtual assets — the same rule of art. 50, advanced to the transitional period.
In other words: the irregular fintech that intended to use the transitional window until May 31, 2027 to continue arbitraging the regime via crypto-rail does not have that window. The prohibition is immediate for all, authorized and in transition.
The structural contradiction with Resolution 519
The most philosophically uncomfortable point of Resolution 561 is what it does when read together with resolutions published by the same Central Bank six months earlier — in November 2025, in the package of BCB Resolutions 519, 520 and 521.
Resolution 519, especially, recognizes virtual asset as a legitimate vehicle for exchange operations. It disciplines the provision of virtual asset services (SPSAVs), formalizes the authorization regime for Brazilian exchanges and custodians, and — key point — makes mandatory, as of May 4, 2026 (three days after the publication of 561), the reporting of every international crypto operation to the Central Bank.
Resolution 521, complementary, formalizes the stablecoin as an eligible asset in currency exchange operations conducted by authorized institutions, with requirements for identification, traceability and counterparty authorized by the BC.
The set of these three norms, read in isolation, describes a regulator that accepts virtual asset as a legitimate financial instrument, requires traceability and supervision, and integrates the segment into the regulated Brazilian financial system. That is how most of the market read the package in November: Brazil officiated crypto.
Resolution 561, published five months later by the same BC, prohibits the use of that same virtual asset as a settlement instrument in eFX — which is, in practice, the most relevant channel of Brazilian retail cross-border. The two norms are not logically contradictory: virtual asset can be legitimate as a vehicle for currency exchange operation conducted by authorized institution (519, 521) and simultaneously prohibited as a means of settlement of eFX (561). But they live in practical tension, because most real use cases of virtual asset in cross-border payments, outside the context of institutions authorized to operate currency exchange, goes through eFX.
The functional result is the following: an institution authorized to operate currency exchange can use stablecoin as a vehicle for currency exchange operation under 519/521. An institution that operates via eFX cannot use stablecoin as a means of settlement under 561. The difference is who operates, not what is operated. And the difference is exactly where the Brazilian retail of cross-border digital payments lives.
The timing: 22, 30, 4, 1, 31
The chronology of relevant events draws a sequence that does not seem, in retrospect, accidental:
- April 22, 2026 (eight days before 561): Foxbit, Brazilian exchange, announced the launch of Foxbit Prime Desk, B2B international currency exchange platform for Brazilian companies with stablecoin settlement "invisible" to the client — exactly the crypto-rail model that 561 closes.
- April 30, 2026: Central Bank publishes Resolution 561.
- May 4, 2026 (three days later): the obligation to report international crypto operations to the BC under Resolution 519 comes into force.
- October 1, 2026: Resolution 561 enters into force.
- October 30, 2026: final deadline for authorized institutions to include eFX in Unicad.
- May 31, 2027: final deadline for irregular eFX providers to request authorization from the BC.
The period between the launch of Foxbit Prime Desk and the publication of 561 — eight days — does not necessarily mean that the Central Bank reacted specifically to one product. Normative resolutions typically have internal elaboration time exceeding months. But the market signal is unequivocal: the BC observed an emerging pattern of B2B products with crypto-rail and closed the gap before it escalated.
Who wins, who loses
The practical incidence reading divides the market into three groups.
Losers:
- B2B fintechs of cross-border via stablecoin (Foxbit Prime Desk and similar) — model needs to be redone by October 1;
- E-commerce platforms with international payment via crypto-rail — same adaptation deadline;
- Informal remittance operators who used stablecoin as bridge to reduce costs — the operation does not become illegal per se (remains possible via non-eFX channels), but loses the option to operate within the regulated regime;
- Companies that were building products under the expectation that the 519/521 framework would cover the eFX use case — will need to reposition the roadmap.
Winners:
- Traditional banks and currency exchange brokers — recover competitive advantage against fintechs that were building cost efficiency via crypto-rail;
- Payment institutions already authorized with currency exchange infrastructure — capture the market of those forced to exit;
- The B3, with its planned real stablecoin — operates within the permitted perimeter (authorized institution, domestic counterparty), avoiding the problem of cross-border crypto settlement;
- Paradoxically, the Visa, whose US$ 7 billion annually stablecoin settlement program operates between authorized institutions (credentialed acquirers and issuers) — does not go through eFX and, therefore, is not covered by 561.
Without material change:
- Brazilian individual who buys, sells or holds crypto via Brazilian exchange — outside the scope of eFX;
- Individual who sends or receives crypto via uncustodied personal wallet — also outside scope;
- Crypto operations between Brazilians — not cross-border operations;
- Brazilian individual's investment in foreign virtual asset via Brazilian SPSAV (governed by 519/521) — does not go through eFX.
What the user should do now
For different profiles, the set of practical actions from today varies.
Brazilian company that uses eFX for international payments: verify with the eFX provider which settlement model is used (conventional currency exchange or crypto-rail). If it is crypto-rail, demand from the provider a transition plan with implementation deadline before October 1, 2026. If the provider does not have BC authorization and is in the art. 56-B regime, consider migration to an authorized provider in the second half of 2026 — before the May 31, 2027 deadline that could capture intermediary institutions in irregular situation.
Brazilian individual: the change does not affect direct purchase of crypto in Brazilian exchange or cross-border sending via personal wallet. It affects only the use of eFX as a channel — products such as international credit cards offered by fintechs with cashback program in stablecoin, for example, may have operational adjustments. In terms of declaration to the BC, the obligation that enters May 4 is of the SPSAV (exchange), not the individual, except operations outside the regulated channel, which need to be declared via DCBE (Declaration of Brazilian Capital Abroad).
Compliance officer / fintech lawyer: read 561 together with Resolution 277/2022 (with amendments) and Resolutions 519, 520, 521 — not as isolated pieces. Map the product architecture against: (1) who is the provider, (2) which eFX modality is provided, (3) which current settlement instrument, (4) where the foreign counterparty is, (5) if code 34038 applies (crypto as purpose) and how it will be reported. Circular 3,978/2020, cited three times in 561 (procedures for knowing the foreign counterparty), remains the operational KYC/AML framework.
Frequently Asked Questions About BCB Resolution 561
What exactly changes with BCB Resolution 561?
BCB Resolution 561, published on April 30, 2026 and effective from October 1, 2026, amends BCB Resolution 277/2022 and prohibits the use of virtual assets as a means of settlement between eFX providers (international payment or transfer service) and their foreign counterparties. The settlement becomes mandatory via traditional currency exchange operation or movement in real account of non-resident held in Brazil. The rule is in art. 50, item I, with new wording.
Did the Central Bank prohibit the use of crypto to send money abroad?
Not in broad sense. Resolution 561 specifically prohibits the use of virtual asset as a settlement instrument in the regulated eFX channel (between the Brazilian provider and the foreign counterparty). Brazilians continue to be able to buy, hold and send crypto via national exchanges or personal wallets. What changes is the specific eFX channel, typically used by fintechs and international payment processors.
When does Resolution 561 come into force?
Resolution 561 comes into force on October 1, 2026, according to art. 4º. There are additional transitional deadlines: institutions already authorized have until October 30, 2026 to include the eFX modality in the Unicad system; irregular providers have until May 31, 2027 to request authorization from the Central Bank as a payment institution.
Can I continue buying Bitcoin or USDT on my Brazilian exchange?
Yes. Resolution 561 does not affect the purchase, sale or custody of virtual assets by an individual via Brazilian exchange (which operates under the regime of Resolutions 519, 520 and 521). The 561 specifically addresses the eFX channel for international payments and transfers.
Can I use eFX to buy crypto from a foreign exchange?
Yes, under specific conditions. Resolution 561 included code 34038 ("virtual assets") in Annex V of Resolution 277/2022, within the purpose "Acquisition of goods and services". This means that the purpose of the eFX operation can be the acquisition of virtual assets. What 561 prohibits is that payment to the foreign exchange be made in virtual asset — it must be in fiat currency (USD, EUR etc.) through traditional currency exchange. Limits: up to US$ 10,000 per operation when there is no integration with electronic commerce platform.
Who is authorized to provide eFX as of October 1, 2026?
Art. 49, § 2º, with new wording, lists: banks, Caixa Econômica Federal, development agencies, credit/financing/investment companies, securities brokers and distributors, currency exchange brokers, and payment institutions authorized by the BC as electronic money issuer, post-paid payment instrument issuer, or acquirer. Legal entities outside that list may continue providing eFX in the transitional regime of art. 56-B, but must request authorization by May 31, 2027.
What happens to fintechs that today do international remittance via stablecoin as rail?
Have until October 1, 2026 to reformulate the settlement model. After that date, settlement between the eFX provider and the foreign counterparty must be exclusively through conventional currency exchange operation or movement in real account of non-resident. The "stablecoin invisible as bridge" model — popularized in 2025-2026 by B2B products like Foxbit Prime Desk, launched on April 22, 2026 — becomes unfeasible within the eFX regime from that date.
Is there a contradiction between Resolution 561 and Resolution 519?
There is no formal logical contradiction, but there is practical tension. Resolution 519 (and 521) recognize virtual asset as a legitimate vehicle in currency exchange operations conducted by institutions authorized to operate currency exchange. Resolution 561 prohibits virtual asset as a means of settlement in the eFX channel. The two norms coexist because they address different layers of the architecture: 519/521 address SPSAVs (exchanges, custodians) and formal currency exchange operations; 561 addresses the specific eFX channel, which typically serves retail and mid-market outside the perimeter of institutions authorized to operate currency exchange.
Does an individual have to do something starting with Resolution 561?
There is no direct obligation created by 561 for an individual. The obligations to report international crypto operations by an individual to the BC continue under the existing regime (DCBE — Declaration of Brazilian Capital Abroad, when applicable, and declaration on income tax as per Federal Revenue rules). The obligation to report monthly to the BC via Currency Exchange System (new art. 81-A) is of the institution that provides eFX, not the end user.
The 12 to 18 month scenario
Some testable predictions:
1. Acceleration of consolidation in the fintech currency exchange sector. Companies that were growing in B2B remittance models via crypto-rail will have two options: either request authorization as a payment institution and refactor settlement architecture by October 1, or be absorbed by already authorized institutions. Expect relevant M&A movement in the second half of 2026.
2. Growth of B3's stablecoin program. With crypto-rail in eFX blocked, the cleanest institutional alternative for digital settlement with stablecoin-like characteristics becomes the real stablecoin that B3 prepares for 2026 — operated within the perimeter of authorized institution and in domestic counterparty, completely avoiding the problem of cross-border virtual asset settlement. The timing favors B3.
3. Migration of products outside the eFX regime. Some existing B2B products may be repositioned as SPSAV (under Resolution 519) instead of eFX, avoiding the 561 prohibition. This requires substantial adjustment — SPSAVs have their own capital, governance and supervision requirements — but is technically possible for cases where the operation can be characterized as virtual asset service rather than international payment.
4. Possible public consultation on adjustments. 561 is, formally, an amendment to a pre-existing resolution. It did not go through specific public consultation before publication. As the eFX regime affects a significant set of operators and there is tension with products already in market, it is reasonable to expect public consultations in the second half of 2026 on operational adjustments — particularly regarding transitional deadlines and specific modalities of each provider category.
The ON3X perspective
Three readings to close:
1. Brazilian crypto regulation has two legal bodies that contradict on the surface and complement in essence. Read superficially, 561 seems to block crypto while 519 legitimizes it. Read with attention, the two norms operate different layers of the same agenda: integrating virtual asset into the Brazilian financial system under the control of the regulator. 519 gives access (legitimacy); 561 closes the loopholes (control). It is the same logic Brazil applied to conventional currency exchange since the 1970s — first permits, then disciplines, then closes the gaps. Whoever read the 519/520/521 package in November as "crypto liberalization" read it wrong. It was construction of complete regulatory framework, and 561 is a natural part of that framework.
2. The timing says everything about the market's state. The launch of Foxbit Prime Desk on April 22, eight days before 561, is not a conspiracy coincidence — it is market evidence. Brazilian crypto and payments companies were operating in the gray space opened between the November/2025 package and subsequent detailed regulation. 561 is the signal that gray is ending. Companies that are still building products under the premise that "there is still time" should re-read the schedule. There is not.
3. For the citizen and investor, crypto remains accessible — but consolidated Brazil is built to be watched. The structurally most important point is what this analysis has tried to emphasize from the beginning: 561 does not close crypto for the average Brazilian. He continues to be able to buy, hold, send and receive. What changes is the nature of the most-used regulated channel by mid-sized company retail — eFX — which, from October on, operates without crypto-rail. For anyone who wants to operate outside the regulated regime, the exit still exists (exchanges, personal wallets, peer-to-peer). But the regulated Brazilian digital payment regime, from PIX to BC-integrated USDC, from B3's stablecoin to post-561 eFX, is built to be permanently visible to the State. The choice that is being presented to the Brazilian market in the coming twelve months is: operate within the regime and be watched, or operate outside and lose institutional comfort. It is not a false choice — both remain viable. But it is a conscious choice that, from now on, every market player needs to make with open eyes.
Resolution 561 is, ultimately, less about crypto than about the design of the Brazilian digital payments system from 2026 to 2030. Virtual asset is just the piece that needed to be addressed. The larger piece, slowly revealed, is the entire architecture — and it is now, almost complete.
