India's decision to allow a 0.4% fee on merchant UPI transactions above Rs 2,000 is set to reshape the economics of the country's digital payments market, potentially strengthening the position of the largest players while narrowing the room for smaller rivals. According to Bernstein estimates, PhonePe and Google Pay could together earn roughly $900 million a year from the new regime by March 2028, a windfall that would reinforce their already commanding share of India's fast-growing payments landscape.
Fee Windfall Ahead
The policy marks a notable shift in a system that has long been defined by zero-cost consumer payments and thin monetisation for app operators. UPI, or Unified Payments Interface, has become the backbone of India's retail digital payments revolution, processing billions of transactions each month and turning mobile payments into a default habit for urban and increasingly semi-urban consumers. But while the platform has delivered scale, it has not always delivered direct revenue for the companies that sit on top of it.
That is what makes the new merchant fee regime significant. By allowing a 0.4% charge on transactions above Rs 2,000, the framework creates a revenue stream that is likely to accrue disproportionately to the largest apps, which already command the most merchant acceptance, consumer traffic and transaction frequency. Bernstein's projection suggests the change could become a material earnings lever over time, especially if higher-value merchant payments continue to migrate onto UPI.
For PhonePe and Google Pay, the benefit is not only the direct fee income. The policy could also deepen network effects by making it more attractive for merchants and consumers to stay within the largest ecosystems. In payments, scale tends to compound: more users attract more merchants, more merchants attract more users, and the resulting density makes it harder for smaller applications to compete on convenience or acceptance.
Rural Push, Higher Stakes
The fee shift may also alter how payment companies pursue growth beyond India's biggest cities. Bernstein said the new regime could encourage apps to expand more aggressively in rural areas, where digital payment adoption remains uneven but is rising steadily. Rural merchant acquisition has long been a challenge because transaction values are often lower and monetisation is limited. A fee structure tied to higher-value transactions could make it more viable for payment firms to invest in merchant onboarding, field sales and local partnerships outside the metros.
That dynamic matters because India's next phase of digital payments growth is likely to come from breadth, not just depth. As UPI penetrates smaller towns and villages, the winners will be those able to combine low-friction consumer interfaces with dense merchant networks and reliable settlement. Larger platforms are better positioned to absorb the cost of expansion, subsidise adoption and cross-sell adjacent financial services.
Smaller rivals, by contrast, may face a tougher strategic choice. The new economics could push them toward focusing on higher-value transactions where fees are more meaningful, rather than competing head-on in low-ticket consumer payments. That would effectively segment the market and leave the mass retail layer even more concentrated among the incumbents.
Competition Under Pressure
The broader policy question is whether a fee regime designed to improve sustainability for payment providers will also entrench market concentration. India's digital payments system has been celebrated globally for scale, interoperability and public infrastructure design. Yet the same features that make UPI powerful can also make it difficult for new entrants to gain traction once a few platforms become the default choice for consumers and merchants.
PhonePe and Google Pay already sit near the centre of that ecosystem. If Bernstein's estimates prove directionally accurate, the new fee structure could provide them with a fresh monetisation engine at a time when investors are increasingly focused on profitability rather than user growth alone. That would likely support continued investment in merchant acquisition, product development and geographic expansion.
For policymakers, the challenge will be balancing sustainability with competition. A fee that improves the economics of the system may be defensible if it helps maintain investment and service quality. But if the result is to further cement a duopoly-like structure, regulators may eventually face pressure to ensure that smaller players are not permanently locked out of meaningful scale.
For now, the message from the market is clear: India's UPI economy is entering a new phase, and the biggest beneficiaries are likely to be the biggest names already standing at the top of the stack.
