The Unstoppable Rise of UPI
Launched in 2016 by the National Payments Corporation of India (NPCI), UPI transformed the nation's payment landscape. It allows users to instantly transfer money between bank accounts using a mobile app, making digital payments seamless, secure, and,
crucially, free for consumers and merchants. This formula has been wildly successful. In July 2026, UPI processed a staggering 23.66 billion transactions worth nearly ₹30 lakh crore. It has become the default payment method for everything from street food vendors to major e-commerce platforms, accounting for over 80% of all retail digital transactions in the country. This growth isn't just a metro phenomenon; it's rapidly expanding into Tier-2 and Tier-3 cities, making digital finance a reality for millions.
The Zero-MDR Conundrum
Herein lies the problem for payment platforms like PhonePe, Google Pay, and Paytm. The engine of UPI's success is the government's zero Merchant Discount Rate (MDR) policy, implemented in January 2020. MDR is the fee merchants typically pay to banks and payment providers for processing a digital transaction. By making it zero for UPI, the government spurred mass adoption. However, this leaves the companies that build and maintain the user-facing apps with no direct revenue from the core payment service. While the government offers some subsidies, they don't cover the full operational costs of running the vast infrastructure, which includes technology, cybersecurity, and fraud prevention. This has created a high-volume, zero-revenue situation, making the payments business itself unsustainable as a primary profit centre.
Pivoting from Payments to Platforms
Faced with this reality, digital payment companies have been forced to evolve. Their business model is no longer about earning from payments but about using their massive user base as a launchpad for other revenue streams. UPI has become a customer acquisition tool, not a profit engine. The new strategy is to cross-sell higher-margin financial products. These apps have transformed into comprehensive fintech platforms, offering services like personal loans, insurance, and wealth management products such as mutual funds and stocks. They earn commissions on these sales. Another key revenue stream is providing value-added services. For a fee, users can pay utility bills, book tickets, or recharge their phones. Companies also charge merchants for subscription services, such as providing payment devices and analytics. Advertising and promotions have also become a significant source of income, with brands paying to reach the apps' enormous and engaged user base.
The Next Frontier: Credit and Global Expansion
The evolution is far from over. The next major shift is the integration of credit with UPI. The linking of RuPay credit cards to UPI allows users to scan and pay via credit, unlocking a new corridor for high-value transactions and potential revenue. Discussions are also underway about potentially reintroducing a calibrated MDR for high-value merchant transactions, which could provide some relief to payment providers without affecting small merchants or consumers. Simultaneously, India is taking UPI to the world. NPCI is actively expanding UPI's footprint internationally, with the system already live in over a half-dozen countries, including France, Singapore, and the UAE. This expansion aims to simplify cross-border remittances and make payments easier for Indian tourists, creating another long-term growth avenue.
