[Brazil's Central Bank May Ban the Use of Crypto Assets for Settlement in Regulated Cross-Border Payment Systems] According to a report by Cointelegraph, the Central Bank of Brazil (Banco Central do Brasil, BCB) has issued Resolution No. 561, prohibiting the use of virtual assets for settlement within the regulated international payment and transfer services (eFX) framework, further tightening the regulation of crypto assets in the cross-border payment sector. Under the new rules, payments and receipts between eFX service providers and their overseas counterparts must be completed solely through foreign exchange transactions or transfers from non-resident Brazilian real accounts, and the use of crypto assets or stablecoins for settlement is not allowed. This restriction also applies to eFX service providers that have not yet been formally included in the approved category but are in a transitional phase. These institutions must apply for authorization from the Central Bank of Brazil by May 31, 2027, if they wish to continue operations.
