India's decision to allow a 0.4% fee on merchant UPI transactions above Rs 2,000 is poised to reshape the country's digital payments market in a way that may entrench the biggest players rather than disrupt them. According to Bernstein estimates, PhonePe and Google Pay could together generate about $900 million a year by March 2028 under the new regime, a scale of monetisation that would strengthen their already commanding positions in the world's largest real-time payments system.
The policy shift marks a notable evolution in how India's Unified Payments Interface is being commercialised. For years, UPI's rapid growth was driven by zero-cost consumer adoption and a broad public-policy push to replace cash with digital transfers. That model created extraordinary transaction volumes but left payment apps with limited direct revenue from merchant flows. The new fee structure changes that equation for transactions above the threshold, opening a path for payment platforms to earn from higher-value commerce while preserving the low-friction user experience that made UPI ubiquitous.
Revenue Scale Up
Bernstein's projection underscores how lucrative even a modest fee can become when applied across India's enormous merchant payment base. PhonePe and Google Pay already dominate UPI usage, giving them the distribution, brand recognition and merchant acceptance needed to capture the bulk of incremental economics. If the fee regime holds and transaction values continue rising, the two platforms could convert scale into durable monetisation without needing to overhaul their core consumer proposition.
That advantage matters because payments in India have long been a winner-takes-most market. Network effects reward the apps that already sit at the centre of consumer and merchant behaviour, and UPI's design has amplified that dynamic. The new fee regime may therefore do less to broaden competition than to reward incumbency, since the largest players are best placed to absorb compliance, merchant integration and sales costs while still extracting meaningful revenue.
Rural Push, Higher Ticket
The policy could also alter the strategic priorities of payment companies. With revenue now more closely tied to merchant transactions above Rs 2,000, apps may have an incentive to expand deeper into rural and semi-urban markets, where digital acceptance is still uneven and transaction values can be more variable. Building merchant density outside major cities could help platforms capture new payment flows and diversify beyond crowded urban markets.
At the same time, smaller rivals may be pushed toward a different strategy: focusing on higher-value transactions where the fee economics are more attractive and where they can avoid competing head-on with the scale advantages of PhonePe and Google Pay. That could mean targeting categories such as electronics, travel, mobility, and other merchant segments where ticket sizes are naturally larger and digital checkout is already more common.
For the broader mobility and automotive ecosystem, the implications are significant. UPI has become central to how Indians pay for fuel, vehicle servicing, ride-hailing, parking and a growing range of EV-related services. If payment platforms intensify their push into merchant acceptance, the sector could see faster digitisation of everyday transport spending, especially in markets where cash still dominates smaller-ticket purchases.
Competitive Fault Lines
The deeper question is whether the new fee regime will widen the gap between the market leaders and the rest of the field. On one hand, monetisation could improve the economics of running a payments business and encourage more investment in merchant acquisition, rural distribution and product innovation. On the other hand, the largest platforms are likely to capture the greatest share of the upside, reinforcing a market structure that already tilts heavily in their favour.
That outcome would fit a broader pattern in India's digital economy: policy changes intended to sustain scale and efficiency often end up strengthening the incumbents that are already best positioned to comply and expand. For consumers, the immediate effect may be limited. For merchants, especially those handling larger ticket sizes, the new fee regime could bring a more formalised cost structure. For the payment industry, however, the stakes are much larger. India's UPI system is entering a phase where volume alone may no longer define success; the ability to monetise that volume may now separate the leaders from the rest.
