India Already Dominates Global Payments — Now It Wants to Own Credit Too
In January 2026, the Unified Payments Interface processed 21.70 billion transactions — accounting for 81% of all retail digital transactions in India and 49% of all real-time payment transactions globally. No payment system in human history has scaled this far, this fast. But 2026 is the year UPI enters its next phase: after more than a year of careful experimentation, Credit Line on UPI — known as CLOU — is beginning to scale, and industry observers are calling it the most significant evolution of India's payment stack since UPI's original launch in 2016.
What Is Credit Line on UPI?
Credit Line on UPI allows banks and regulated financial institutions to extend pre-approved credit lines directly into users' UPI apps. Instead of applying for a credit card, waiting for approval, and managing a separate product, a user with CLOU can pay via UPI and have the transaction debited from a bank-sanctioned credit line rather than their savings account balance. India has approximately 75 crore active UPI users but only about 10 crore credit cardholders. CLOU essentially brings credit access to the 65 crore UPI users who have never had a formal credit product — with their UPI payment history serving as the creditworthiness data.
RBI's New Security Mandates
The Reserve Bank of India implemented mandatory two-factor authentication for all digital payments effective April 1, 2026. The new requirements add verification layers — including biometrics, PINs, or secure tokens — alongside existing OTP systems. The RBI's governance stance has also drawn attention to market concentration issues: PhonePe (backed by Walmart) and Google Pay collectively command over 80% of UPI transaction volume, a dominance that regulators have been attempting to address through market share caps that have proven difficult to enforce in practice.
UPI Goes Global: 8 Countries and Counting
Beyond India's borders, UPI is now operational or linked with payment systems in the UAE, Singapore, Bhutan, Nepal, Sri Lanka, France, Mauritius, and Qatar. The National Payments Corporation of India is in active discussions with several additional countries across Southeast Asia and the Middle East. This international expansion transforms UPI from a domestic payment rail into a genuine global infrastructure play — particularly important for India's diaspora population, which sends approximately $120 billion in remittances annually, much of which currently flows through expensive traditional wire transfer channels.
India's Fintech Sector Shifts Focus to Credit in 2026
The broader India fintech sector is experiencing a decisive pivot from payments infrastructure to credit products. Having established the world's most advanced real-time payment rail, India's fintech innovators are now building the lending layer on top of it. Companies from HDFC and ICICI to fintechs like Slice, KreditBee, and LazyPay are all developing CLOU-adjacent products. The total addressable market for digital credit in India is estimated at $1.3 trillion by 2030 — a number that contextualises why CLOU's scaling is being watched so closely by both domestic and international investors.
