Brazil’s central bank will require covered institutions to report virtual-asset transfers valued at $10,000 or more to or from self-custody wallets to the Financial Activities Control Council, known as Coaf, from October 1, 2026. Resolution BCB No. 588, published September 23, amends the country’s anti-money-laundering and counter-terrorist-financing framework under Circular No. 3,978. The measure applies to transfers in both directions and is a reporting requirement, not a ban, transaction cap or transfer freeze. The resolution does not mandate automatic aggregation of multiple transfers below $10,000, although suspicious transactions remain subject to separate monitoring and reporting obligations. A distinct anti-fraud rule, Resolution BCB No. 584, can permit up to 24-hour retention of certain outbound transfers from January 1, 2027 and aggregates a customer's transfers during one day. Resolution BCB No. 589 separately requires supervisory information on customer assets, custody, proof of reserves and staked assets from January 1, 2027, while restrictions on dealings with unauthorized virtual-asset counterparties begin November 6, 2026.
