2026-06-25 | Resolução CMN 5320The Central Bank of Brazil, acting on behalf of the National Monetary Council, mandates financial institutions and payment institutions to block accounts and halt transactions for individuals and entities operating unauthorized fixed-odds betting lotteries. Institutions must execute these blocks within twenty-four hours of receiving a notification from the Ministry of Finance's Prize and Betting Secretariat and implement procedures to prevent further irregular transactions. Failure to comply with these blocking and reporting obligations subjects the institutions to penalties established under Federal Law No. 14,790 of 2023.
