All non-authorized payment institutions participating in PIX must submit formal BCB authorization requests by May 1, 2026. BCB Resolution 429 accelerated the original December 2026 deadline by seven months. Institutions that fail to apply face exclusion from the PIX ecosystem. The requirement applies to institutions that joined PIX from July 2024 onward without holding a formal BCB payment institution authorization.
The accreditation mandate operates alongside several other restrictions introduced since late 2025. Resolution 546, published January 22, 2026, imposed a R$15,000 per-transaction cap on non-authorized institutions and those connecting via PSTI intermediaries. Since January 1, 2026, transactional account providers must maintain minimum share capital and net equity of R$5 million. Resolution 547, published January 30, 2026, raised requirements for PSTI technology providers to a minimum R$15 million in realized capital and mandatory international security certifications.
Total SPI participants peaked at 934 in June 2025. By February 2026, that count had declined to 916. This marks the first sustained contraction since a brief dip in late 2023. The BCB has separately identified up to 31 indirect participants that failed to comply with the March 4, 2026 intermediary migration deadline. Salary accounts become eligible for PIX Automatico operations from July 2026.
