India’s UPI accelerates global expansion with new cross-border interoperability milestones

India’s Unified Payments Interface is transforming into a model for international instant payment connectivity, with expansion into 13 countries and a strategic shift towards cross-border interoperability amid surging transaction volumes.

India’s Unified Payments Interface has reached a scale that few payment systems anywhere in the world can match, and its latest growth figures point to a new phase in its development. According to data from the National Payments Corporation of India, UPI processed 23.2 billion transactions in May 2026, worth ₹29.9 trillion, underlining how deeply the rail has been woven into everyday commerce. The scale matters because it is no longer just a domestic success story; it is becoming a model for how instant payments could work across borders.

That broader opportunity was the central theme of a Business Today report on the next stage of UPI’s expansion. The article said the real prize is interoperability, meaning the ability to connect different instant-payment systems so that money can move between countries as easily as it does within them. Boston Consulting Group’s The Burden of Proof: Global Payments Report 2026 said 137 countries had state-owned or mandated 24/7 instant-payment systems by June 2026, showing how quickly real-time payment infrastructure is spreading around the world.

UPI’s international footprint is already expanding through partnerships led by NPCI International Payments. Business Today said Indian users can now use UPI across 13 country-market arrangements, including Singapore, the United Arab Emirates, France, Mauritius, Sri Lanka, Nepal, Qatar, Greece, Cambodia and Uzbekistan. The form that connectivity takes varies by market: Singapore first supported person-to-merchant payments in August 2021 and later linked PayNow for person-to-person transfers in February 2023, while the UAE, France, Mauritius and Sri Lanka followed in 2022 and 2024. More recently, Greece added person-to-person connectivity in May 2026, Nepal expanded into person-to-person payments in June, Cambodia enabled merchant payments in June, and Uzbekistan became the latest addition.

For Indian travellers, students and business users, the practical benefit is clear: more places where they can pay without leaning on cards or cash. For merchants, direct links between payment systems can open access to foreign customers without routing every transaction through older card networks. The strategic case is even larger. BCG said domestic account-to-account systems are increasingly challenging global card networks for simple payments, although complex cross-border commerce, advanced authentication and tokenised transactions remain much harder to replace. With global payments revenue forecast by BCG to rise from nearly $2 trillion in 2025 to about $2.6 trillion by 2030, the fight is shifting from domestic payment dominance to cross-border connectivity. As Business Today put it, the next opportunity for India is not only to make UPI bigger, but to make it more connected.
