Banco Central do Brasil published Resolution BCB No. 561 prohibiting settlement via virtual assets (including stablecoins) inside regulated eFX cross‑border payment rails. Payments/receipts between eFX providers and foreign counterparties must instead be executed through foreign‑exchange transactions or movements in non‑resident BRL accounts. Transitional provisions allow unapproved providers to continue until they obtain central bank approval by May 31, 2027, but they also cannot use virtual‑asset settlement. The move follows broader VASP and stablecoin tightening amid concerns about taxation, AML and monetary sovereignty; stablecoins reportedly account for about 90% of reported crypto flows.

The central bank rule explicitly disallows virtual‑asset settlement (including stablecoins) in regulated cross‑border eFX rails and forces use of FX or non‑resident BRL accounts; transitional approval deadline is May 31, 2027. The summary states stablecoins make up ~90% of reported crypto flows and the change is driven by taxation, AML and monetary‑sovereignty concerns—facts that imply reduced on‑rail crypto settlement demand.
