The Banco Central do Brasil will enforce three PIX regulatory deadlines within a 20-day window starting April 22. The Phase 2 mandate under BCB Resolution 541 requires all mandatory PIX participating institutions to make NFC contactless payments publicly available by that date. Twelve acquirers have confirmed NFC acceptance support, including Cielo, Stone, and Rede. Nubank launched unified NFC on April 7, joining Itau, Bradesco, PicPay, C6 Bank, and Banco Inter as issuers offering PIX por Aproximacao. The feature remains Android-only. CADE's formal investigation into Apple's NFC restrictions has produced no public resolution since the March 30 response deadline.
The May 1 accreditation deadline under BCB Resolution 429 requires non-authorized payment institutions that joined PIX from July 2024 to submit BCB authorization applications. Minimum share capital and net equity of BRL 5 million have been required since January 1, 2026. Institutions connecting via non-accredited technology service providers face a R$15,000 per-transaction cap under Resolution 546. BCB has signaled it may exclude up to 31 indirect participants that failed to migrate to compliant intermediaries by a March 4 deadline.
MED 2.0 enters production on May 11. The upgrade replaces the legacy single-account fraud recovery mechanism. Complementary participant testing began on April 13. The upgraded system enables cascade fund tracing across up to five intermediary accounts with automatic preventive blocking at each stage. Legacy MED 1.0 recovered R$459 million from R$4.9 billion in confirmed PIX fraud during 2024, a 9 percent recovery rate. Industry estimates project MED 2.0 could reduce successful fraud by up to 40 percent. Its effectiveness against social engineering scams, which account for an estimated 80 to 90 percent of current losses, remains uncertain.
The compressed compliance calendar creates overlapping burdens for smaller institutions. PIX's participant base contracted from 934 institutions in June 2025 to 916 as of February 2026. The combined weight of NFC rollout, accreditation documentation, and MED 2.0 integration may accelerate that decline among indirect participants relying on third-party technology providers now subject to their own accreditation requirements under Resolution 498.
