Brazil to Flag $10K Self-Custody Crypto Transfers From Oct 1
From 1 October, crypto firms in Brazil must report transfers of $10,000 or more to or from self-custody wallets. Holding your own keys stays legal.
Brazil will start watching large crypto transfers into and out of personal wallets. From 1 October 2026, regulated crypto companies in the country must report any transfer worth $10,000 or more that goes to or comes from a self-custody wallet. The Central Bank of Brazil announced the rule on 23 September as part of a wider anti-money-laundering package.
Key takeaways
- The rule is BCB Resolution No. 588. It takes effect on 1 October 2026.
- Reports go to COAF, Brazil's financial intelligence unit.
- It applies both ways: from an exchange to a personal wallet, and from a personal wallet to an exchange.
- $10,000 is a reporting trigger, not a limit. Transfers are not blocked or capped.
- Users do not file anything themselves, and self-custody wallets do not need to be registered.
What the rule says
A self-custody wallet is one where you hold the private keys yourself, such as a hardware wallet or a mobile wallet app, rather than leaving coins with an exchange. Under Resolution No. 588, when a customer of a regulated Brazilian crypto firm sends $10,000 or more worth of crypto to such a wallet, or receives that much from one, the firm must file a specific report with COAF.
The threshold mirrors Brazil's rule for physical cash: moving $10,000 or more in banknotes in or out of the country is already reported in the same way. The central bank is treating a hop into a private wallet as a similar point where money can leave the regulated system.
A second rule in the same package, Resolution No. 584, allows firms to hold certain transfers for up to 24 hours as a precaution. That part starts on 1 January 2027.
What it does not do
The rule does not ban self-custody and does not cap how much you can move. Brazilians can still hold crypto in their own wallets and send any amount. Nothing needs to be blocked. The change is about visibility: the authorities will now see when large amounts cross the line between regulated firms and private wallets.
Why Brazil is doing this
Brazil is one of the world's biggest crypto markets and topped the latest Chainalysis adoption index, with India sixth (see our report on the 2026 index). Stablecoins make up around 80% of the transaction volume declared in the country. Since July, crypto transactions have also been reported to Brazil's tax authority through a system called DeCripto, which follows the OECD's Crypto-Asset Reporting Framework.
Money-laundering rules around the world have long had a gap at self-custody. Exchanges know their customers, but once coins reach a private wallet, the trail is harder to follow. Brazil's approach is to flag the large jumps rather than restrict wallets.
How India compares
India has no rule yet that singles out transfers to self-custody wallets by amount. But Indian exchanges registered with the FIU already follow the travel rule and know-your-customer checks, and they now report users' crypto trades to the Income Tax Department (see how that reporting works). Every sale on an Indian exchange also carries 1% TDS, which leaves a paper trail of its own.
If you move coins to your own wallet in India, keep records of every transfer: date, amount, network and wallet address. They help you work out your 30% tax correctly and answer any notice. Our guide to hot vs cold wallets explains the options for holding your own keys.
