Brazil’s central bank has introduced new rules requiring virtual asset service providers to hold certain large cryptocurrency transfers for up to 24 hours. The measure, outlined in Resolution BCB No. 584/2026 published on August 7, targets transfers exceeding the equivalent of $10,000 sent to foreign virtual asset firms or self-custody wallets.

The threshold applies to a single transaction or the combined total of a customer’s transfers in one day. Smaller transfers may also face the same delay if flagged under an institution’s risk-management policies. The rules take effect on January 1, 2027.

Scope of the New Requirements

The hold applies when a customer deposits Brazilian reais or cryptocurrency with an exchange and then seeks to send the funds abroad or to a self-controlled wallet. Institutions must notify customers when a transaction is placed on hold and document any decision to release funds earlier than 24 hours if a risk review finds no issues.

The central bank stated that the measure is precautionary and does not freeze assets permanently or block transfers indefinitely. After the review period, institutions must either release the transfer or reject it based on risk assessment criteria that consider the customer, transaction details, counterparty, and destination jurisdiction.

Virtual assets referenced to fiat currencies, such as stablecoins, fall explicitly under the rules. The central bank linked the changes to the increasing use of digital assets, including stablecoins, to move proceeds from financial scams quickly across borders before recovery efforts can succeed.

Implementation and Compliance Demands

Crypto platforms operating in Brazil must upgrade monitoring systems to identify qualifying transfers and track cumulative daily volumes per customer. Previously, transfers were often reviewed individually; the new approach requires aggregate daily analysis to detect patterns that might indicate attempts to circumvent limits.

The January 1, 2027 effective date provides time for institutions to adjust systems and procedures. The central bank retains authority to require longer holds, extend the process to lower-value transactions, or limit early releases in cases of noncompliance.

This builds on earlier regulatory steps. Since 2023, cryptocurrency exchanges and service providers in Brazil have been required to register with the central bank as part of a broader framework for overseeing the digital asset sector.

Industry Response and Context

Crypto industry groups raised concerns during a public consultation that closed on July 2. Abcrypto, an association representing firms including major international platforms, argued that the retention period would not effectively target illicit activity and could disadvantage legitimate users and institutions that rely on rapid transfers as an alternative to traditional systems.

Regina Pedroso, president of Brazilian tokenization group Abtoken, noted that the policy could raise costs for legitimate users and reduce the competitiveness of domestic exchanges.

Brazil’s cryptocurrency market has grown substantially, with on-chain activity reaching significant levels in recent periods. Authorities have pointed to rising illicit flows linked to scams, money laundering, and other activities as justification for tighter controls on cross-border movements.

The rules apply specifically to institutions within the Brazilian Payment System that handle virtual assets. Transfers below the $10,000 threshold remain outside the automatic hold requirement, though risk-based reviews can still apply.

Exchanges must ensure systems can detect both individual high-value transfers and cumulative daily activity that meets or exceeds the limit. Customers sending larger amounts abroad or to personal wallets will need to account for potential processing delays once the rules take effect.
