Overview
- The Central Bank of Brazil published Resolution BCB No. 584/2026 on Aug. 7, 2026, and the rule takes effect Jan. 1, 2027.
- The rule automatically applies to transfers that exceed the equivalent of $10,000 in a single transaction or in aggregated transfers by a customer in one day.
- Covered transfers to foreign virtual-asset service providers and to self-custody wallets may be held for up to 24 hours while exchanges run documented risk assessments and notify customers.
- The central bank can require longer holds, lower the $10,000 trigger, or limit early releases when it finds noncompliance, and exchanges must keep daily fraud records.
- Industry groups warn the rule will add costs and delay legitimate activity, and regulators and markets in other countries such as Japan are watching Brazil as a possible model for anti-fraud controls.
