India’s Unified Payments Interface processes over 18 billion transactions a month and has been described as India’s most consequential tech export. Examine UPI’s global footprint and the systemic risks of payment concentration.

Introduction: NPCI reported 18.4 billion UPI transactions worth ₹24.77 lakh crore in March 2025, making it the world's largest real-time retail payments rail and arguably India's most consequential tech export since its launch on 11 April 2016 by the National Payments Corporation of India.

Body: First, global footprint — UPI is live in UAE, Singapore (PayNow linkage from February 2023), France (Eiffel Tower from February 2024), Sri Lanka, Mauritius, Bhutan, and Nepal, anchoring India's digital diplomacy. Second, concentration risk — PhonePe and Google Pay together command over 85% market share against NPCI's 30% market-share cap (deferred to 31 December 2026), creating systemic single-point-of-failure risk. Third, zero-MDR for P2M up to ₹2,000 strains payment-aggregator economics; Budget 2025-26 carries a ₹1,500 crore incentive scheme.

Way forward: Operationalise the 30% cap by end-2026, expand UPI-PayNow style linkages across BIMSTEC, scale UPI Lite 2.0, and price small-merchant MDR transparently under RBI by FY27.
