Developments: 3. The official Tesouro Direto mobile application for Android and iOS has been deactivated as of Monday, 17 August 2026. This deactivation is part of a transition by the Brazilian Treasury toward a new digital experience for investors, though specific details or a launch date for a replacement platform have not been released. Prior to the shutdown, the Treasury noted that the program serves approximately 3.69 million investors with roughly R$ 262.5 billion in securities. To manage public bond investments following the deactivation, users must utilize the online Portal do Investidor—accessing it via CPF, Gov.br credentials, or financial institution login details—or use the applications of authorized banks and brokerages. The Treasury has emphasized that the closure does not affect existing holdings, invested amounts, yields, or historical operation data, all of which remain unchanged on the B3 registry. Investors are not required to take any action to preserve their holdings. ## Timeline ### 2026-08-16: Tesouro Direto deactivates mobile application The Tesouro Direto app has been deactivated.
