India's decision to allow a 0.4% fee on merchant UPI transactions above Rs 2,000 is poised to do more than alter the economics of digital payments. It may also harden the market structure around the country's two most powerful consumer payment platforms, PhonePe and Google Pay, giving them a larger revenue base and more room to widen their lead over smaller competitors.
Bernstein estimates that the two apps could collectively generate about $900 million a year by March 2028 from the new merchant fee regime. That projection underscores how a policy change, designed to create a monetisation path for the UPI ecosystem, could end up reinforcing the incumbents that already command the most users, the most merchant acceptance and the strongest brand recall. In a market where scale is everything, the ability to collect fees on higher-value transactions may become a structural advantage rather than a simple revenue stream.
Scale Advantage Deepens
UPI has long been celebrated as a public digital payments rail that enabled rapid adoption without direct consumer charges. But the system's success has also created a difficult business question: how do payment apps earn sustainable revenue when the core service is free for users? The new merchant fee regime offers one answer, but not a neutral one. It rewards platforms that already sit at the center of transaction flows and have the merchant relationships to capture value quickly.
PhonePe and Google Pay are especially well placed because they dominate consumer mindshare and transaction volumes. A fee on merchant payments above Rs 2,000 could disproportionately benefit them as larger-ticket purchases increasingly move through the system. That includes categories such as electronics, travel, services and, importantly for this sector, mobility-related spending where higher-value transactions are more common than in low-ticket retail.
For the broader automotive, EV and mobility ecosystem, the implications are significant. As more vehicle purchases, charging payments, subscriptions, insurance premiums and after-sales services migrate onto digital rails, the platforms that control payment access gain leverage across the value chain. The fee regime may therefore strengthen the intermediaries that sit between consumers, merchants and mobility providers, making them even more central to the digital commerce stack.
Rural Push, Rival Pressure
The policy could also reshape competitive behaviour. Bernstein's view suggests the new fee structure may encourage payment apps to expand more aggressively into rural areas, where merchant penetration is still uneven and transaction growth remains a major opportunity. For the biggest players, rural expansion is not just about volume; it is about building a wider network that can support future monetisation as transaction sizes rise.
Smaller rivals, by contrast, may face a harsher reality. With limited scale and weaker distribution, they are likely to be pushed toward higher-value transactions if they want to participate meaningfully in the fee pool. That could force them to specialise, consolidate or seek niche use cases rather than compete head-on with the market leaders in everyday retail payments.
The result may be a more stratified UPI market: dominant incumbents capturing the bulk of the economics, while smaller players struggle to justify the cost of customer acquisition and merchant onboarding. In that sense, the fee shift could accelerate a trend already visible in India's digital payments landscape — a winner-takes-most dynamic built on network effects, merchant acceptance and trust.
Policy Meets Market Power
The government's move reflects a broader effort to make the UPI ecosystem more commercially sustainable without undermining adoption. Yet any monetisation framework in a market as concentrated as India's payments sector inevitably has distributional consequences. A fee on merchant transactions above a threshold may appear modest, but over time it can translate into meaningful revenue for the largest platforms and a widening gap between leaders and followers.
That gap matters because payment apps are no longer just payment apps. They are distribution channels, data engines and customer acquisition platforms for lending, commerce, insurance and mobility services. Whoever controls the transaction layer can influence what gets sold, how often and to whom. For PhonePe and Google Pay, the new regime may therefore do more than boost earnings. It could entrench their role as gatekeepers in India's digital economy.
For smaller competitors, the challenge is not only to survive the fee shift but to find a differentiated path in a market where scale is increasingly rewarded by policy as well as by consumer behaviour. The new UPI economics may have been designed to support the ecosystem. In practice, it may end up making the biggest players bigger.
