Starting October 1, 2025, the Securities and Exchange Board of India (Sebi) is introducing a new way to make payments in the securities market safer and more transparent. If you invest in stocks, mutual funds, or any market-linked product, this new move is for you. Sebi now requires all registered brokers, mutual funds, and other intermediaries to use a validated Unified Payments Interface (UPI) identification (ID) to collect payments from investors.
