Brazil stablecoin ban: what changed on October 1 for businesses selling to Brazilians

The news: what the Brazil stablecoin ban actually says

On April 30, 2026, the board of the Banco Central do Brasil (BCB) approved Resolution BCB 561. It rewrites the part of Resolution BCB 277/2022 that governs eFX, Brazil's regulated service for small-value international payments and transfers. That service covers Brazilians buying goods and services from sellers abroad, withdrawals in Brazil or abroad, transfers to other people and between a person's own accounts and, from now on, transfers linked to investments. The resolution was published in the official gazette on May 5 and, under its article 4, took effect on October 1, 2026 (official text of Resolution BCB 561).

The heart of it is the new article 50. Any payment or receipt between an eFX provider and its counterparty abroad must now be made "exclusively" through a foreign-exchange operation or through a non-resident account in reais held in Brazil, "sendo vedado o uso de ativos virtuais": the use of virtual assets is prohibited. When the rule was published, CoinDesk summed up the practical effect. A remittance company can no longer take a customer's reais, turn them into USDT, USDC or bitcoin, and settle the payment abroad on a blockchain (CoinDesk's report).

The rest of the resolution tightens the same service:

• Only authorized institutions may offer eFX. The list covers banks, Caixa, development agencies, credit and financing companies, broker-dealers, FX brokers, and payment institutions authorized as e-money issuers, post-paid instrument issuers or acquirers. Those already authorized must register the eFX modality in the BCB's Unicad system by October 30, 2026.
• Unauthorized providers get a runway, not an exemption. They must apply for authorization by May 31, 2027, or stop within 30 days. Until then they work under tighter limits and the same ban on settling in virtual assets.
• A US$10,000 cap applies to purchases made through a provider's digital payment solution when it isn't integrated with an e-commerce platform. The new investment transfers carry the same cap.
• Know the counterparty. The provider must have a contract with its counterparty abroad, run Brazil's anti-money-laundering customer checks on it, and keep records for ten years.

The firms that feel it first are the cross-border fintechs that had put a stablecoin leg inside their remittance and payment products to settle faster and cheaper. CoinDesk named Nomad and Braza Bank among them. The market they built on is large. According to the same report, Brazil's crypto market moves US$6 billion to US$8 billion a month, and stablecoins account for roughly 90% of that volume.

The second rule that landed the same night: self-custody transfers become reportable

October 1 brought a second change that got less attention. On September 23 the BCB issued Resolution 588, which adds a line to Brazil's anti-money-laundering rulebook, Circular 3.978/2020. Authorized institutions must report to COAF every "transferência de ativos virtuais para ou de carteiras autocustodiadas", a transfer of virtual assets to or from a self-custodied wallet, worth US$10,000 or more.

One day before it was due to take effect, the board replaced it. Resolution BCB 591, approved on September 30 and published in an extra edition of the official gazette on October 1, keeps the same threshold and scope but changes the timing. Reports for transfers made between October 1 and December 31, 2026 are filed on the first business day of January 2027 (official text of Resolution BCB 591). Some early coverage still describes the revoked version.

This sits on top of the framework that took effect on February 2, 2026. Resolution BCB 521 already treats international payments made with virtual assets as foreign-exchange operations. It requires providers to identify the owner of a self-custodied wallet, and it caps an international payment or transfer with virtual assets at US$100,000 when the counterparty isn't authorized to operate in Brazil's FX market. Two points are worth keeping straight. US$10,000 is a reporting threshold, not a limit or a ban. And a report to COAF is not an accusation.

Brazil's crypto rule calendar, October 2026 to May 2027

Put together, the resolutions form a schedule. Here is what binds whom, and when:

The analysis: Brazil took stablecoins out of the plumbing, not out of people's wallets

Read the resolutions side by side and a pattern appears. None of them regulates the token. Each one targets an intermediary at a specific moment: an eFX provider settling with a partner abroad, a supervised institution sending crypto to a self-custodied wallet or receiving it from one, a provider releasing a large withdrawal. The BCB isn't saying stablecoins are illegal. It's saying that inside the regulated payment system, the currency leg has to show up in the FX statistics, under a contract it can audit.

The reasons aren't hard to find. An eFX payment settled through an FX contract leaves a record with a purpose code, a counterparty and an amount. The same payment settled in USDT leaves a transaction hash that the central bank's FX system never sees. Analysts also point to monetary sovereignty, since most stablecoins used in Brazil are dollar tokens issued by foreign companies. The resolution's annex shows exactly where the line runs. It keeps a dedicated purpose code, 34038, for eFX purchases classified as virtual assets. Buying crypto from abroad remains a recorded purchase. Using crypto as the settlement pipe is what's gone.

Two consequences follow. First, part of the price advantage some cross-border fintechs offered came from settling outside the FX market. That advantage is closing, so their costs should move toward those of traditional FX providers. Second, the demand doesn't disappear. Stablecoins are already about 90% of Brazil's crypto volume, and that money stays where it was: in people's and companies' wallets and in authorized exchanges, where the BCB can now count it.

This is the same boundary this blog traced in August with Brazil's 24-hour hold on transfers to self-custody. The regulator polices the crossing between a supervised institution and a private wallet. It doesn't dispute that the wallet exists.

Selling to Brazilians after October 1: three routes, three rulebooks

If you sell to customers in Brazil, the useful question isn't whether stablecoins are allowed. It's which route each payment takes, because the rules land on a different intermediary in each one.

Route 1: the customer pays in reais through a cross-border payment provider

This is the classic flow. The customer pays with Pix, a boleto or a bank account. An eFX provider collects the reais and settles with its partner abroad, who then pays you. Since October 1, that settlement abroad has to be an FX operation or a non-resident reais account. It can't be crypto.

If your provider sold you faster settlement, lower fees or a USDC payout option built on a stablecoin leg, ask three questions. How does the Brazilian leg settle now? Do pricing or timing change? And do any of your payment links or invoices count as a digital payment solution not integrated with an e-commerce platform, which carries the US$10,000 cap per purchase?

Route 2: the customer pays from stablecoins held at a Brazilian exchange

This isn't eFX. It's a virtual-asset transfer handled by the customer's provider under Resolution 521. When the customer sends USDT or USDC to your wallet, their exchange treats an international payment as an FX operation. It has to identify who owns the receiving self-custodied wallet, which is yours, and it applies the US$100,000 cap per operation when the counterparty isn't authorized in Brazil's FX market.

Since October 1, a transfer of US$10,000 or more gets reported to COAF. From January 1, 2027, transfers above US$10,000 to self-custodied wallets or foreign crypto firms can be held for up to 24 hours before they go out. In practice, large tickets take longer, and your customer's exchange will want to know who is being paid. A clear invoice helps them answer.

Route 3: the customer pays from their own self-custodied wallet

Wallet to wallet, with no Brazilian institution in the middle at the moment of payment. The rules still apply at the edges: where the customer's coins entered the regulated system, and where yours leave it if you convert through a Brazilian provider. If your business is in Brazil, converting stablecoins to reais through an authorized provider is itself an FX operation under Resolution 521. Your own obligations depend on where you're incorporated and what you do with the funds. That's a question for counsel, not for a payment processor.

Where Payzum fits, and where it doesn't

Payzum is a non-custodial, crypto-only payment processor. A customer's payment goes from their wallet straight to a wallet you control. Payzum never holds, pools or controls the money. It settles in crypto, with optional auto-convert to USDC or USDT so you don't carry volatility. That defines its place in the three routes:

• Route 1 isn't Payzum. Payzum doesn't take reais, doesn't operate eFX and doesn't settle fiat. If your Brazilian customers want to pay with Pix, you need an authorized eFX provider.
• Routes 2 and 3 are. Payzum serves customers who already hold stablecoins or other crypto and want to pay with them, on Ethereum, Solana, Polygon, Base, Arbitrum, Optimism, BNB Chain, Avalanche or Bitcoin.
• It isn't a way around anyone's rules. In the BCB's vocabulary, your Payzum settlement wallet is a self-custodied wallet. Your customer's exchange still identifies its owner, still reports transfers of US$10,000 or more, and from 2027 can still hold large ones. Payzum doesn't change what their provider must do.

What Payzum changes is what happens on your side once the customer sends. The payment is final on-chain in seconds, about 0.4 seconds on Solana and about 2 seconds on Base and Polygon, and it lands in your wallet rather than in a platform balance. There are no chargebacks. Invoices expire and flag overpayments, signed webhooks tell your systems when a payment confirms, an audit log records who did what, and KYC is built into the product.

How to set up stablecoin checkout for Brazilian customers, step by step

1. Choose networks your customers' exchanges actually send on. Offer USDT and USDC on low-fee networks such as Polygon, Base and Solana, and Ethereum for larger tickets. A lot of USDT in Latin America moves on Tron, which isn't a Payzum network, so tell customers which networks you accept before they send. Our USDT vs USDC comparison covers which coin to take.
2. Connect your own wallet and decide what you hold. Every payment settles there directly. Turn on auto-convert to USDC or USDT if you want dollars rather than volatile assets.
3. Issue one checkout or invoice per order. Use hosted checkout or a drop-in plugin for your store, and Payzum invoices for B2B: a fixed amount, a receiving address and an expiry. Give large invoices a longer window, because from January 2027 your customer's exchange can hold transfers above US$10,000 for up to 24 hours.
4. Give the customer a clean record. Make sure what you send shows your business name, the order reference, the amount, the network and the address. That's what their exchange will ask about when it identifies the owner of the receiving wallet.
5. Automate fulfillment and keep the trail. Wire signed webhooks so orders ship on confirmation, and keep the audit log and the on-chain transaction hashes for your accountant.

Where this lands in practice

Three businesses, three different mixes of routes:

• A US software company with Brazilian customers. It keeps card and Pix billing through its cross-border provider (route 1) and adds USDC invoices for customers' finance teams that hold dollars on a Brazilian exchange (route 2). A US$24,000 annual plan crosses the reporting line now and the hold line in 2027, so the company sets a 72-hour expiry on those invoices and warns customers about the exchange's checks up front.
• An online store in Mexico or Portugal that ships to Brazil. Most shoppers still pay with Pix through the store's provider. A smaller group holds stablecoins and would rather pay with them. A hosted checkout on Polygon and Base serves that group, with no chargebacks on that share of sales and the money landing in the store's own wallet. It's the same setup we describe for accepting crypto payments from customers abroad.
• A Brazilian design studio billing clients abroad. Clients in the US and Europe pay USDC invoices straight to the studio's wallet, and the eFX change doesn't touch that leg. When the studio converts to reais, it does so through an authorized Brazilian provider. Under Resolution 521 that conversion is an FX operation, and a deposit of US$10,000 or more from self-custody gets reported. Payzum doesn't convert to reais, so the studio plans conversions with its accountant.

eFX provider vs. direct stablecoin payment after October 1

To be fair to the left column: for most Brazilian shoppers, Pix through a good provider is still the easiest way to pay you. A stablecoin checkout doesn't replace it. It serves the customers who already hold dollars on-chain, and it settles to you on different terms.

Fair objections

"Isn't accepting stablecoins from Brazilians a way around the new rules?"

No, and you shouldn't treat it as one. Resolution 561 governs how eFX providers settle. It doesn't stop a Brazilian from paying with crypto they hold legally. When they do, their own provider applies Resolutions 521 and 591, and Resolution 584 from 2027. A direct stablecoin payment is a different route with its own rules, not a gap in the system.

"Will Brazil ban stablecoins outright next?"

Nobody can promise what a regulator does next. The direction of the past year has been to license, measure and slow down, not to prohibit: stablecoin trading brought under FX rules in February, reporting and holds at the edge of self-custody now, authorization deadlines running into 2027. Keep your setup flexible. Accept on more than one network, and convert on a schedule.

"My provider still pays me in USDC. Is it breaking the rule?"

Not necessarily. The rule covers the Brazilian provider's settlement with its counterparty abroad, and how that counterparty pays you afterwards is a separate step. Ask your provider how the Brazilian leg settles now, and get the answer in writing.
