Binance will require Brazilian users to disclose the purpose and counterparty of cross-border crypto transfers starting Nov. 1. Incomplete submissions can block withdrawals or delay deposits, and the exchange will report the transactions monthly to Brazil's central bank under new foreign-exchange rules.
Binance will block withdrawals and delay deposits for Brazilian users who fail to explain cross-border crypto transfers starting Nov. 1. The exchange is adding the checks to comply with a new Brazilian central bank rule on international virtual-asset flows.
New disclosure rule takes effect Nov. 1
Binance said customers sending crypto abroad or receiving it from nonresidents must disclose the purpose of each transfer and identify the counterparty type, and corporate accounts must state whether the other party belongs to the same economic group. The exchange will report the transactions monthly to Brazil's central bank under Resolution BCB No. 521/2025, which brings international virtual-asset transfers into the country's foreign-exchange framework.
Withdrawals cannot be submitted until the questionnaire is completed. Incoming deposits can remain pending and, in some cases, get returned if users do not provide the required information. The rules cover individuals and companies moving crypto to or from nonresidents, including transfers to a customer's own accounts on foreign exchanges, while transfers between Brazilian residents stay unaffected.
Transfers of as much as $50,000 use a simplified list of ten purposes, while larger transfers require customers to pick from 96 classifications, and some international transfers are capped at $100,000 when the counterparty cannot operate in Brazil's foreign-exchange market. Self-hosted wallet transfers skip the purpose questionnaire but still require users to confirm wallet ownership.
Part of a broader surveillance push
The change extends a wider Brazilian effort to pull crypto payments, self-custody wallets and cross-border transfers deeper into financial-surveillance and foreign-exchange oversight. Regulated institutions must already report transfers worth at least $10,000 involving self-custody wallets to Brazil's Coaf by the next business day, even without a suspicious-activity flag.
Brazil has also restricted stablecoin use in a specific aggregated cross-border payment structure used by foreign-exchange providers. Stablecoin transactions accounted for about 72% of declared crypto activity between August 2019 and December 2025 in that market. Binance said the new transfer rules are separate from Brazil's Travel Rule, which phases in for domestic transactions in 2027 and international transfers in 2028. A further tightening arrives Jan. 1, when Resolution BCB 584 introduces precautionary holding procedures that can delay certain outbound transfers.
