What we do

Working in close collaboration with Brazil’s Securities Commission (CVM) and Central Bank, our team acts to ensure that institutions and their professionals comply with market regulations. Our main activities are:

  • market surveillance – we monitor 100% of orders and trades in B3's markets in order to identify signs of irregularities;
  • auditing – we audit all B3 Participants to check their compliance with the regulations and to identify possible infractions of market rules;
  • disciplinary processes and other enforcement actions – when regulations are infringed we adopt guidance, persuasion or disciplinary measures such as letters of recommendation, letters of censure or Disciplinary Administrative Proceedings, in accordance with the severity of the irregularity that has been identified;
  • compensation of losses – we analyze and adjudicate complaints presented to the Investor Compensation Mechanism (MRP), which awards damages of up to BRL 120,000 to investors harmed by an Exchange Participant’s inappropriate activity;
  • market development – we develop education initiatives, rule enhancements and institutional relationships with market participants, regulatory bodies and international organizations.
