The Brazil Securities Commission (CVM) published a March 2025 roundup covering new rulemaking, supervisory guidance, enforcement actions and key reports. The main regulatory updates were a new rule to regulate innovations introduced by Law 14.711 and a targeted change to CVM Resolution 193 to facilitate voluntary adoption of CBPS 01 (IFRS S1) and CBPS 02 (IFRS S2). Supervisory circular letters set expectations for the minimum registration data for EAMOs and IOSMFs, clarified the limited liability of real estate investment fund (FII) unitholders, and announced enhancements to the E‑Net system.
