India's Unified Payments Interface has expanded to 15 new countries in its latest deployment wave, bringing the total to 32 countries where Indian travellers and NRIs can use UPI-linked accounts for real-time payments — a network covering markets from Japan and South Korea to France and the Netherlands.

Cumulative international UPI transactions have crossed ₹50,000 crore since the global rollout began in 2022, according to data from the National Payments Corporation of India. Transaction volumes are growing 340 per cent year-on-year, driven by Indian diaspora payments and a growing base of merchant acceptance abroad.

The Gulf expansion is particularly significant: the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, and Oman together account for over 10 million Indian workers whose remittances of approximately $45 billion annually represent a critical portion of India's foreign exchange receipts. UPI processing these flows at near-zero transaction cost compared to traditional remittance corridors could substantially reduce the fee burden on migrant workers.

Several countries are now examining whether to interlink their own real-time payment rails with UPI — a development that would create bilateral payment corridors without the need for dollar intermediation.
