_*SEBI to Implement New UPI Address System for Stock Market Transactions*_ *Why in News:* SEBI announces a new UPI address mechanism set for implementation by October 1, 2025, aimed at safeguarding investors from fraudulent, unregistered entities. *Key Points:* * SEBI’s new UPI system will feature a unique identifier, @valid, combined with intermediary names and category suffixes (e.g., ‘.brk’ for brokers). * The system aims to protect investors by making it easier to identify legitimate, SEBI-registered intermediaries. * Investors will see a green thumbs-up icon for secure transactions with registered entities. * All registered intermediaries must adopt these validated UPI IDs, phasing out old ones by October 1, 2025. * Investors will still have alternative payment options but must use the new UPI ID if choosing this method. * SEBI is launching ‘SEBI Check’, a tool to verify the authenticity of UPI IDs, further ensuring secure transactions.
