Brazil’s 24-hour hold
Brazil’s Central Bank will require cryptocurrency exchanges to hold for up to 24 hours certain outbound transfers starting January 1, 2027, under Resolution BCB No. 584/2026 published on August 7, 2026.
“Resolution BCB No. 584/2026, published on August 7, 2026”
The rule applies when transactions exceed $10,000 or its equivalent, including when that threshold is reached through multiple transactions during the same day, and it also covers transfers to overseas platforms or to a self-custody wallet under the user’s control.
The Central Bank says the measure is aimed at curbing the use of digital assets in financial fraud schemes by creating a time window for detection before funds move out of investigators’ reach.
Banco Central do Brasil (BCB) rules also require providers to notify customers when a transfer is placed on hold and to maintain records of fraud attempts, incidents and corrective measures.
Providers can release a transaction before the 24-hour period expires if their risk assessment meets parameters set by the central bank.
What triggers the delay
The hold is triggered when a user deposits Brazilian reais or cryptocurrencies on an exchange and then requests to send those funds to an exchange located abroad or to a self-custody wallet under their own control.
Criptoinforme says the platform must withhold the operation for a maximum period of 24 hours when certain risk criteria established by the regulation are met, and it adds that lower-value transactions may also be delayed when exchanges detect risk signals.
BitKE similarly describes that the threshold can apply based on a customer’s total transfers during a day, while other transactions may be held for review under a provider’s risk-management procedures.
The regulation is described as preventive rather than a permanent freeze, because exchanges can authorize the transfer before 24 hours have elapsed if the operation shows no signs of illicit activity.
In addition to the $10,000 trigger, the rules place responsibility on exchanges to assess factors such as the customer profile, the characteristics of the transaction, the counterparty involved, and the destination jurisdiction of the funds.
Industry pushback and stakes
The new Brazil transfer controls have drawn criticism from Regina Pedroso, president of Abtoken, who said the policy could raise costs for legitimate users and reduce the competitiveness of Brazilian exchanges.
“The move is in response to criminals using cryptocurrencies such asstablecoinsto move money obtained via fraud”
PYMNTS frames the central bank’s move as a response to criminals using cryptocurrencies such as stablecoins to move money obtained via fraud before it can be recovered, and it says the hold is temporary.
PYMNTS also reports that exchanges must document the decision to release a transfer early and inform customers when a transaction has been placed on hold.
The Cryptonomist adds that the central bank’s stated rationale centers on timing, saying a 24-hour buffer gives banks, exchanges, and victims a fighting chance to intervene before stolen or scammed funds disappear across borders.
Across the coverage, the rule’s implementation date remains January 1, 2027, and the described compliance burden falls on virtual-asset service providers to run risk analysis and keep records of fraud or attempted fraud and corrective measures.
