Brazil will require covered financial institutions to report qualifying virtual-asset transfers of $10,000 or more involving self-custody wallets to the country's Financial Activities Control Council (COAF), Brazil's financial-intelligence unit, beginning October 1, 2026. The new rule from the Central Bank of Brazil adds another layer of anti-money-laundering (AML) oversight without banning self-custody or limiting transaction amounts, and it is separate from the country's forthcoming 24-hour retention measure that starts 2027.

$10,000 Threshold Is a Reporting Trigger, Not a Cap

The Central Bank of Brazil published Resolution BCB No. 588 on September 23, amending the country's existing AML framework to add qualifying virtual-asset transfers involving self-custody wallets to mandatory reporting requirements. The reporting obligation applies from October 1, 2026.

Under the rule, transfers of $10,000 or more to or from self-custody wallets must be reported to the Financial Activities Control Council (COAF) whenever covered institutions handle the transfers in either direction. The $10,000 figure serves as a reporting trigger rather than a transaction limit or a ban on self-custody. Users can therefore continue holding and transferring cryptocurrency through wallets controlled by their own private keys.

Resolution 588 also does not require institutions to automatically block qualifying transactions. Instead, the reporting responsibility rests on institutions covered by Brazil's financial regulatory framework.

The central bank said self-custody can reduce the information available for monitoring and risk assessment. Regulated custodians, by contrast, maintain customer and transaction records within supervised financial institutions. The reporting trigger is aimed at that gap: it generates records at the point where funds move between supervised institutions and wallets operating outside the regulatory perimeter, without restricting the transfers themselves. The announcement was additionally published on the Brazilian government's official portal.

Separate From Brazil's 24-Hour Retention Rule

Resolution 588 is distinct from Resolution BCB No. 584, which introduced a different measure targeting certain crypto transfers. Resolution 584 allows qualifying outbound transactions to self-custody wallets or foreign virtual-asset providers to face temporary retention. That 24-hour retention measure begins on January 1, 2027, rather than October 1, 2026, and uses a different threshold calculation from the reporting requirement introduced under Resolution 588.

Notably, Resolution 584 permits same-day transfers by the same customer to be aggregated when determining whether its threshold is reached. Resolution 588 contains no equivalent automatic aggregation provision for its reporting trigger.

The absence of aggregation language does not remove institutions' existing obligations covering suspicious transactions. Institutions must continue assessing activity that could indicate money laundering or terrorist financing under Brazil's established AML framework.

Brazil Expands Oversight of the Crypto Market

The new requirement forms part of Brazil's broader effort to strengthen oversight of digital assets. Resolution 588 follows earlier measures covering licensing, capital requirements, governance, security and compliance for virtual-asset providers — the building blocks that brought virtual-asset activity inside Brazil's supervised financial system.

The Central Bank also issued Resolution BCB No. 589 on September 23. The measure introduces additional supervisory information requirements involving customer balances, custody positions, proof of reserves and assets committed to staking. Some provisions under Resolution 589 take effect on January 1, 2027. Meanwhile, restrictions affecting dealings with unauthorized virtual-asset service providers are scheduled to begin on November 6, 2026.

The effective dates set up a staged rollout to track: reporting on self-custody transfers starts in October 2026, restrictions on dealings with unauthorized providers follow in November, and the retention measure along with parts of Resolution 589 arrive in January 2027.

Together, the September 23 measures extend the supervisory perimeter around Brazil's virtual-asset market. For crypto users, the October rule therefore changes reporting visibility rather than self-custody access. Transfers meeting the $10,000 threshold will enter Brazil's existing financial-intelligence reporting process whenever covered institutions facilitate them.
