On November 10, 2026, Brazil’s National Monetary Council (CMN) and Central Bank approved Joint Resolution No. 21, amending the rules for Open Finance partnership agreements and facilitating data sharing by business customers. The new rules require participating institutions to assess their partners’ compliance and data protection capabilities, with certification issued by an independent auditor registered with the Brazilian Securities and Exchange Commission (CVM). Customers must provide explicit authorization in the integrating institution’s environment, and must authorize each partner separately. Partnership agreements must also provide for the prompt suspension of data sharing in the event of a security incident, and prohibit subcontracting the partnership and sharing the relevant data with third parties.
