Brazil Bans Crypto in Cross-Border Payments: Fiat-Only Rules Hit Banks, Fintechs

Brazil shuts crypto out of its official cross‑border payment pipes

Brazil’s central bank has prohibited the use of cryptocurrency for settling payments within the country’s official electronic foreign exchange system. This means banks and financial technology companies must now use traditional currency for international money transfers.

Summary

  • Brazil’s central bank has banned the use of cryptocurrencies for settlement inside regulated cross‑border payment rails, forcing banks and fintechs to use only traditional FX and real‑denominated accounts.
  • The move, formalized in a new foreign‑exchange resolution, comes as authorities say roughly 90% of reported cross‑border crypto remittances involve stablecoins, raising concerns over tax evasion, money laundering, and monetary sovereignty.
  • The rule does not outlaw crypto in Brazil, but it walls off virtual assets from the supervised eFX system that underpins formal remittance channels and instant‑payment integrations like the central bank’s Pix network.

Brazil’s central bank has created a new rule preventing official international payment systems from using cryptocurrencies to complete transfers. This strengthens the controls around how money is formally sent into and out of the country.

New FX rules wall off crypto from Brazil’s eFX rails

As reported by crypto.news, a new rule – Resolution BCB No. 521 – prevents banks, payment companies, and money transfer services from using their existing international payment systems to settle transactions involving cryptocurrencies. Essentially, it blocks crypto assets from being processed through these standard channels.

As an analyst, I’ve been following Brazil’s moves in the crypto space, and it’s interesting to see how they’re tightening regulations. Previously, they’d categorized stablecoin transactions and exchanges involving traditional currency as foreign exchange activity. Now, they’re going a step further: these digital assets are completely barred from being used for settlements within Brazil’s established electronic foreign exchange system. Essentially, they’re cutting off stablecoins from being used as a payment method within that regulated system.

Not a blanket ban, but a hard boundary

Coverage from Phemex stresses that this is not a country‑wide ban on crypto usage.

In Brazil, people and businesses can continue to buy, sell, and trade cryptocurrencies like Bitcoin and stablecoins on exchanges or directly with each other. However, they are now prohibited from using these cryptocurrencies to complete payments through officially regulated foreign exchange services.

According to Coinness, the central bank wants to make sure all international payments are processed using standard currency exchange methods or through accounts that regulators can fully monitor for money laundering prevention.

Officials are concerned that allowing banks to settle foreign exchange transactions using offshore stablecoins or other cryptocurrencies could weaken their ability to monitor money moving in and out of the country and make it harder to track taxable income.

Stablecoins, remittances, and what happens next

The rush to regulate stablecoins in Brazil is largely due to how widely they’re used. Regulators believe around 90% of cryptocurrency-based money sent into the country now uses dollar-linked tokens like USDT and USDC. The central bank is concerned this could weaken efforts to prevent money laundering and make it harder to monitor foreign exchange activity.

Brazilian and Latin American financial technology companies are quickly developing low-cost ways to send money internationally using cryptocurrency. For example, Mercado Libre is currently testing a system that allows free stablecoin transfers between Brazil, Mexico, and Chile, but users only see transactions in traditional currencies.

The new regulation seems intended to create a clear distinction: any service wanting to use the established electronic foreign exchange system must settle transactions using traditional currency, not cryptocurrencies. Companies offering crypto-based money transfers can still operate independently, but they won’t be part of the central bank’s regulated payment system.

Brazil’s handling of crypto and stablecoins is part of a growing trend among global regulators. It involves letting these markets operate, but keeping them isolated from the main financial systems used for managing money supply and international money flows. This approach aims to protect those core systems from potential risks associated with crypto.

Brazilian cryptocurrency users and developers now face the task of creating products that can succeed alongside the country’s existing payment systems, or persuading officials that a secure form of token-based transactions can be integrated into Brazil’s closely monitored financial infrastructure.
