Before joining the Ministry of Finance, Fabio Macorin served in Brazil’s Federal Police for 17 years. For a decade, he focused specifically on the investigation and prevention of banking and financial fraud. This experience helped shape his approach to betting regulation, particularly regarding anti-money laundering, financial monitoring, combatting the illegal market and inter-agency cooperation.

Brazil’s regulated betting market formally launched in 2025 and has since become one of the most closely watched regulatory initiatives in the global gaming and betting sector. Macorin, who also served as the SPA’s undersecretary for monitoring and enforcement, has been directly involved in initiatives to combat illegal operators, strengthen cooperation with financial institutions, telecommunications providers and other government authorities, as well as develop data-driven tools for regulatory oversight and enforcement.

Commenting on his election, Macorin expressed his honour at joining the IAGR board and contributing Brazil’s experience to the association’s international work.

The focus is on identifying illegal and unregulated gambling sites, operators that offer gambling services without the necessary licence, as well as sites that misuse, copy, or falsely refer to other operators’ licences.
