The official Banco Central do Brasil normative registry confirms Resolução BCB n° 561 was issued on April 30, 2026. The Block, which links directly to the official BCB text, confirms the rule amends the eFX framework to exclude virtual assets (cryptocurrencies and stablecoins) from cross-border payment settlement, requiring use of traditional FX transactions or nonresident BRL accounts instead. Crypto.news, SpaceMoney, and TechCripto all independently corroborate the prohibition. The May 31, 2027 transitional authorization deadline is consistent with the broader VASP regulatory timeline described by The Block (nine-month grace period from February 2026). The only minor uncertainty is that the full text of Resolution 561 was not directly readable from the BCB page fetch, so the precise May 31, 2027 deadline wording could not be independently verified from the primary source text itself; however, all secondary sources and the claim's framing are mutually consistent.
