Brazil's central bank will require crypto transfers above $10,000 sent to foreign virtual-asset platforms or self-custody wallets to be held for up to 24 hours before completing, under new anti-fraud rules set to take effect in October 2026. The threshold can be measured either per single transaction or against a customer's cumulative transfers within one day, closing an obvious workaround where a large transfer could otherwise be split into smaller pieces.
The central bank said the rule responds to the growing use of virtual assets, including stablecoins, to rapidly move money obtained through financial scams — a pattern regulators globally have flagged as stablecoins have become a faster settlement rail than traditional banking for cross-border transfers.
Not a freeze, but a checkpoint
Brazilian authorities were explicit that the measure is not designed to permanently block transfers. Virtual-asset service providers can release funds before the 24-hour window closes if their own internal risk checks determine the transfer is safe, giving companies a built-in mechanism to avoid delaying legitimate transactions unnecessarily. The delay functions more as a cooling-off period that gives compliance teams and, potentially, fraud victims a window to flag a transaction before it's irreversible.

Part of a broader regulatory tightening
Brazil's move fits a wider pattern of regulators treating large or cross-border crypto transfers as a fraud vector that needs friction, not just disclosure requirements. Reporting on the proposal noted the rule specifically targets transfers to platforms outside Brazil's regulatory perimeter, reflecting concern that funds moved to foreign exchanges or unhosted wallets are harder to claw back once a scam is discovered. With an October 2026 start date, exchanges and stablecoin issuers serving Brazilian customers now have roughly two months to build the delay mechanism and the risk-scoring systems needed to release funds early when appropriate.
