Brazil’s central bank has introduced a rule that will require crypto firms to delay certain outbound transfers for as long as 24 hours before releasing them. The measure is aimed at transactions that regulators consider harder to monitor and recover once funds leave the local system.
Published on Aug. 7 as Resolution BCB No. 584/2026, the rule takes effect on Jan. 1, 2027. It updates Brazil’s 2021 fraud-prevention framework for payment providers so that it explicitly covers crypto assets and stablecoins.
Which transfers will be delayed
The hold applies when a single transfer, or a customer’s combined outbound transfers in one day, exceeds $10,000 and the destination is either a self-custody wallet or a virtual asset platform based outside Brazil.
Transfers that remain inside a regulated domestic exchange are excluded from the requirement. Movements between accounts on the same platform are also outside the scope of the rule.
How the rule is meant to work
The central bank said the requirement should function as a review period rather than a freeze. In practice, qualifying transfers are still expected to be completed, but not immediately.
Smaller transfers are not automatically exempt from scrutiny. An exchange may still delay them if its own risk controls identify suspicious activity. If a firm decides to release funds before the full waiting period ends, it must document that decision and notify the customer.
Compliance pressure on crypto firms
The resolution gives the central bank room to escalate restrictions against institutions that do not follow the requirements. According to the rule, the regulator can extend the waiting period, broaden its application to smaller transfers, or limit a firm’s ability to authorize an early release.
That structure puts the burden on crypto service providers to build and document internal processes for screening outbound transfers that fall under the new thresholds.
Fraud prevention is the stated objective
The central bank linked the measure to a pattern it says appears repeatedly in crypto-related fraud. In those cases, victims often realize they were scammed only after their funds have already been sent beyond the domestic system or into a wallet controlled solely by the sender or by a fraudster.
By inserting a mandatory delay at those exit points, the regulator is trying to create time for review before funds move to destinations that are more difficult to police or recover from once the transfer has been completed.
Next confirmed step
Resolution BCB No. 584/2026 is scheduled to come into force on Jan. 1, 2027. Until then, the confirmed change is that crypto firms operating under the framework will need to prepare for a 24-hour hold on qualifying outbound transfers to self-custody wallets and foreign platforms.
