The Unstoppable Rise of UPI
From paying for street-side chai to high-value online shopping, UPI has become the invisible lifeline of India's economy. Launched in 2016, it has witnessed exponential growth, cementing itself as one of the world's largest real-time payment systems.
In July 2026 alone, the network processed over 23 billion transactions. This widespread adoption was no accident. It was the result of a deliberate strategy to make digital payments as simple and seamless as exchanging cash, fundamentally altering consumer behaviour and bringing millions into the formal financial fold.
The Zero-Cost Conundrum
The magic of UPI for users and merchants is its cost: zero. This was achieved by eliminating the Merchant Discount Rate (MDR), a fee merchants typically pay to banks and payment processors for every digital transaction. In January 2020, the government mandated a zero-MDR policy for UPI to supercharge adoption. While the move was wildly successful in boosting transaction volumes, it created a financial paradox. The very infrastructure that supports billions of free transactions—servers, security systems, and inter-bank settlements—carries significant operational costs.
Who Actually Pays the Price?
If users and most merchants aren't paying, who is? The financial burden falls on the participants of the UPI ecosystem: the banks, payment service providers (PSPs) like PhonePe and Google Pay, and the National Payments Corporation of India (NPCI), which operates the system. These entities incur costs for every transaction they process. To offset this, the government has provided financial subsidies to the industry, but these have been viewed as a temporary solution rather than a permanent funding model, leaving a widening gap between the cost of running the system and the revenue it generates.
The Search for a Sustainable Model
The core of the problem is that while UPI is a fantastic customer acquisition tool, it is not a direct revenue stream. This has forced payment apps to innovate, turning their platforms into financial marketplaces. They now generate income by cross-selling other products like loans, insurance, and mutual funds, or by charging for value-added services such as bill payments and advertising. For these companies, UPI is the gateway, not the destination. The strategy is to build a large user base with free payments and then monetize that user base through other financial services.
A Public Good or a Commercial Service?
The government has consistently maintained that UPI is a digital public good, essential for financial inclusion and a cashless economy. This perspective clashes with the commercial realities faced by the private players who invest in and maintain the ecosystem. Recently, however, there has been a shift in conversation. A bill passed by the Lok Sabha in August 2026 enables the government to introduce a calibrated MDR for certain transactions in the future. The government has clarified that any potential fee would be nominal and targeted only at high-value merchant transactions, ensuring that person-to-person payments and small merchants remain unaffected.
