UPI transactions surge over 5 years; 12 countries adopt India’s digital payment system
The Unified Payments Interface (UPI), which completed a decade of operation in 2026, has recorded a sharp multi-year rise in transaction volume and value.
UPI transaction volumes grew roughly ten-fold over the past several years, moving from a few billion transactions annually to well over a hundred billion transactions a year.
UPI's international arm has extended the payment rails to a growing number of countries, with acceptance now live across a broadening set of markets in Asia, the Gulf and Europe.
The expansion has been driven through both merchant-acceptance tie-ups (allowing Indian travellers to pay abroad via UPI) and bilateral real-time-payment linkages between national payment systems.
UPI as India's real-time payment system
UPI is an instant, mobile-based, real-time payment system that allows fund transfers between bank accounts using a Virtual Payment Address (VPA), without requiring bank account numbers or IFSC codes to be shared with the payee. It was developed and is operated by the National Payments Corporation of India (NPCI), and it rides on the Immediate Payment Service (IMPS) settlement infrastructure while adding a unified, interoperable interface across banks. It became operational in 2016 and has since become the dominant mode of digital retail payment in India by transaction volume.
Key Details
- Operator: National Payments Corporation of India (NPCI), incorporated December 2008 as a Section 8 (not-for-profit) company under the Payment and Settlement Systems Act, 2007, jointly promoted by the RBI and the Indian Banks' Association.
- UPI became operational in 2016; regulated by the RBI under the Payment and Settlement Systems Act, 2007.
- India accounts for a very large share (roughly half) of the world's real-time payment transaction volume, per recent international data citing UPI as the world's largest real-time payments platform.
- UPI now handles a large majority of India's total digital payment transaction volume.
The reported multi-year surge in UPI transactions reflects the underlying growth curve NPCI has publicised around UPI's ten-year milestone in 2026, underscoring UPI's shift from a domestic innovation to the backbone of India's digital payments ecosystem.
NPCI International Payments Limited (NIPL) and cross-border UPI acceptance
NPCI International Payments Limited (NIPL) is the wholly owned international arm of NPCI, set up to take UPI and RuPay beyond India through two broad models: (a) merchant-acceptance partnerships that let Indian UPI users pay abroad by scanning local QR codes (e.g., via link-ups with foreign payment networks), and (b) bilateral real-time-payment interlinkages that let a partner country's own citizens use their local instant-payment app to pay into UPI-linked merchants, similar to India's own linkage with Singapore's PayNow. Countries where UPI-based payment acceptance has gone live in some form include Bhutan, Nepal, Sri Lanka, Singapore, the UAE, France, Mauritius, and Qatar, with further tie-ups (including in Southeast Asia) under active discussion.
Key Details
- NIPL: NPCI's dedicated international subsidiary for exporting UPI/RuPay payment rails.
- Two models: merchant QR acceptance abroad, and bilateral fast-payment-system interlinkage (e.g., India–Singapore UPI-PayNow linkage).
- Live markets include Bhutan (first to adopt UPI outside India), Nepal, Sri Lanka, Singapore, UAE, France, Mauritius and Qatar, among others expanding through 2026.
- Strategic goal: reduce cross-border remittance costs and position UPI as an exportable digital-public-infrastructure (DPI) model.
The reported expansion to about a dozen countries fits the pattern of NIPL's twin-track strategy, extending UPI acceptance for outbound Indian travellers while also building inbound linkages for foreign users, reinforcing India's "digital public infrastructure diplomacy."
Digital Public Infrastructure (DPI) and the India Stack
UPI is one layer of the broader "India Stack" — a set of public digital infrastructure comprising identity (Aadhaar), payments (UPI) and data-sharing consent (Account Aggregator framework) — often cited internationally as a model of "Digital Public Infrastructure" (DPI) that other countries and multilateral bodies (including the G20 during India's 2023 presidency) have referenced as a template for low-cost, interoperable, at-scale digital finance.
Key Details
- India Stack layers: Aadhaar (identity), UPI (payments), Account Aggregator/DEPA (consented data-sharing).
- G20 2023 (India's presidency) formally endorsed DPI as a policy priority for member and developing countries.
- UPI's near-zero-MDR (merchant discount rate) model has been cited as key to its scale versus card-based systems abroad.
The cross-border UPI push is consistent with India's broader diplomatic strategy of promoting its DPI stack as an export product, alongside financial-inclusion and remittance-cost benefits for the Indian diaspora in adopting countries.
- UPI became operational in 2016; NPCI (its operator) was incorporated in December 2008.
- UPI transaction volumes have grown roughly ten-fold over the past several years, crossing well over a hundred billion transactions annually.
- India's UPI accounts for close to half of the world's real-time payment transaction volume, per recent international assessments.
- UPI acceptance is live, in various forms, across roughly a dozen countries including Bhutan, Nepal, Sri Lanka, Singapore, UAE, France, Mauritius and Qatar, with further expansion ongoing in 2026.
