UPI-ASBA implementation timeline extended to ease phased transition and ensure stakeholder readiness for retail applications. The circular extends the Phase I commencement date for implementing Unified Payments Interface (UPI) with Application Supported by Block Amount (ASBA) for retail public issue applications by three months, while Phase II and Phase III schedules remain unchanged and will begin after completion of the revised Phase I. Market intermediaries and other entities involved in public issue processing are directed to take required steps to comply, and the earlier November 1 circular is modified to that extent under the regulator's procedural powers.
