Who we are

BSM is the B3 group’s self-regulation division. It has administrative and budgetary autonomy to perform surveillance activities in the markets that B3 operates by:

  • Providing guidance for B3’s markets
  • Monitoring operations, orders and transactions in trading environments
  • Auditing B3 participants
  • Operating the investor compensation mechanism (MRP)
  • Bringing administrative actions against those in breach of the rules.

Pursuant to these goals, we monitor operations, orders and trades executed in our trading environments, supervise market Participants and, if necessary, apply penalties against those who infringe regulations.

The capital market plays an important part in Brazil’s economic development. It meets a large part of companies’ financing requirements and protects against market fluctuations.

It is also an important investment alternative for individuals and corporations that want to earn from their savings. We are committed to promoting market integrity and protection for investors and other market agents. We follow the highest ethical standards in strict compliance with the laws and with market best practices.

BSM Market Supervision follows the B3 Code of Conduct, which deals in broad terms with the values that guide the B3 Group. This demonstrates how the B3 Group’s collaborators are committed to the rules of business and social ethics and to principles of transparency, equal rights, diversity and accountability, being duty bound to both internal and external compliance.
