Brazil's central bank has published Resolution BCB No. 584/2026, introducing a mandatory delay of up to 24 hours for certain cryptocurrency transfers exceeding the equivalent of $10,000. The rule takes effect on January 1, 2027, and applies to transfers destined for foreign virtual asset service providers or self-custody wallets.
The measure amends Resolution BCB No. 142 from 2021, which previously governed fraud prevention in payment services, extending those controls to companies providing virtual asset services. Under the new framework, the hold triggers on a single transaction above the threshold or on the cumulative value of a client's same-day operations. Transfers below $10,000 may also be paused if an institution's risk management policies flag them based on the client's profile, the transaction's characteristics, the counterparty, or the destination jurisdiction.
The central bank framed the delay as a precautionary screening window rather than a permanent restriction. Institutions must notify customers when a hold is applied and document the decision. They may release funds before the 24-hour period expires if a reasoned risk assessment finds no signs of wrongdoing; otherwise, they must either execute or reject the transfer once the window closes.
