Digital Currency / UPI & CBDC — UPSC Mains Model Answer

UPI is operated by the National Payments Corporation of India (NPCI), a not-for-profit entity promoted by the Reserve Bank of India and a consortium of banks. NPCI functions as the umbrella organisation for retail payment systems, providing the interoperability layer that connects banks, third-party applications, and end users seamlessly.

A Virtual Payment Address (VPA) allows a user to link multiple bank accounts, enabling flexible fund transfers without exposing sensitive account details. This design choice enhances both security and user convenience, distinguishing UPI from earlier payment instruments. Immediate fund settlement, 24×7 availability, and zero-cost person-to-person transfers have driven mass adoption across income segments.

UPI has achieved remarkable transaction volumes, making India's real-time payment system one of the largest globally by volume. This scale has reduced dependence on cash, improved tax compliance through traceable transactions, and lowered the cost of financial intermediation for small merchants and informal sector workers.

Market concentration among a few large third-party application providers raises systemic risk and competition concerns. NPCI has deliberated on market-share caps to prevent monopolistic dominance. Balancing innovation incentives with prudential regulation remains an ongoing policy challenge, particularly as UPI expands internationally through bilateral arrangements.
