The Central Bank of Brazil mandates that crypto exchanges impose a maximum 24‑hour delay on certain outbound transfers to overseas platforms and self‑custody wallets, as part of revised anti‑fraud measures.
The rule becomes effective on January 1, 2027, pursuant to Central Bank Resolution No. 584/2026, which was released on August 7.
It applies when a user deposits Brazilian reais or places cryptocurrency with an exchange, then attempts to move the funds abroad or into a wallet they control.
Transfers valued at more than $10,000 — whether executed in a single transaction or across multiple transfers within a single day — will be subject to the mandatory hold. Smaller amounts may also experience delays if an exchange deems them suspicious.
The Central Bank noted that cryptocurrencies, including stablecoins, are increasingly employed to transfer proceeds of financial fraud before victims or authorities can intervene.
The restriction is not permanent; exchanges may release a transaction earlier if their risk assessment determines no fraud indicators are present. Such decisions must be documented and communicated to the affected customer.
The directive also places greater responsibility on exchanges to assess risk based on factors such as the customer’s profile, the transaction details, the counterparty involved, and the destination jurisdiction.
