Ten years ago this week, a modest interface called the Unified Payments Interface went live with 21 banks and barely 90,000 transactions in its first month. Few could have guessed that it would become the engine room of India’s digital economy. Today, the platform processes, within a single day, more transactions than most countries manage in a year.

The numbers tell their own story. Annual transaction volume has climbed from 1.78 crore in FY2016–17 to over 24,162 crore in FY2025–26, an almost 13,000-fold surge. Transaction value has risen from a modest ₹0.07 lakh crore to around ₹314 lakh crore over the same period, a nearly 4,000-fold increase. The number of banks live on the platform grew from 21 in April 2016 to 741 in July 2026. Last month alone, UPI recorded a record 2,366 crore transactions, averaging 66 crore transactions every day. The International Monetary Fund has recognised UPI as the world’s largest real-time payment system by volume, accounting for close to half of all real-time payments processed worldwide.

What sets UPI apart from digital payment systems built elsewhere is not just its scale, but its architecture. Rather than concentrating volumes inside one dominant app, India built a common digital framework that any licensed player could plug into and compete through. This has kept the system open, interoperable and resistant to any single point of failure. That design choice, more than any marketing push, explains how UPI scaled to hundreds of banks and reached nearly every corner of the country within a decade.

Behind this growth sits a less discussed driver: the merchant network itself. Recent research suggests that merchant acceptance, rather than consumer enthusiasm alone, has been the real force multiplier. Districts with a denser network of merchants accepting UPI have consistently shown faster consumer adoption, demonstrating that last-mile acceptance infrastructure mattered as much as the app on a customer’s phone.

In our Bank , the number of active UPI customers grew 21 per cent year on year, from 2.29 crore in FY25 to 2.77 crore in FY26, while UPI transaction volume grew 35 per cent year on year in the last quarter, from 176 crore to 237 crore. Mobile banking users climbed 23 per cent to 2.48 crore over the same period. Taken together, 95 per cent of all customer transactions at the Bank during the quarter were carried out digitally, up from 93 per cent a year earlier. Digital channels originated business worth ₹67,327 crore during the quarter, up 16 per cent year on year.

UPI’s architecture has also started to travel. Since February 2023, UPI has been bilaterally linked with Singapore’s PayNow, allowing users of either system to send real-time, low-cost remittances. It was the first such link for India’s fast payment system.

Indian travellers can already scan a UPI QR code to pay merchants directly in Bhutan, France, Mauritius, Nepal, Qatar, Singapore, Sri Lanka and the UAE.
