India's decision to allow a 0.4% fee on merchant UPI transactions above Rs 2,000 is poised to reshape the economics of the country's most important digital payments rail, and the immediate beneficiaries appear to be the incumbents already sitting at the top of the market. Bernstein estimates that PhonePe and Google Pay together could generate about $900 million in annual revenue from the new regime by March 2028, a forecast that underscores how even a modest fee change can translate into large-scale commercial advantage when applied to India's vast transaction volumes.
Incumbents Gain Scale
The policy shift matters because UPI has long been defined by zero-cost consumer payments and razor-thin monetisation for apps that built enormous user bases without a clear path to profitability. By introducing a merchant fee on transactions above a relatively high threshold, the system begins to reward scale, distribution and merchant acceptance in a way that naturally favours the largest players. PhonePe and Google Pay already command dominant positions in India's UPI ecosystem, and the new framework could entrench that lead by giving them a direct revenue stream from the very network they helped popularise.
Bernstein's estimate suggests the opportunity is not merely incremental. A $900 million annual revenue pool by March 2028 would be meaningful even for large consumer internet businesses, particularly in a market where payments have historically been used as a customer acquisition tool rather than a standalone profit engine. For the two front-runners, the fee regime could help offset the heavy costs of merchant onboarding, incentives and infrastructure, while also giving them more room to invest in product development and distribution.
Rural Push, Higher Tickets
The new structure may also alter strategic behaviour across the sector. Analysts expect payment apps to intensify their push into rural India, where merchant digitisation remains uneven and where the next wave of growth may come from first-time acceptance rather than pure transaction frequency. If the economics improve on merchant payments, platforms have a stronger incentive to recruit small businesses outside major urban centres and to widen the acceptance network that underpins UPI's long-term growth.
At the same time, the fee regime could encourage smaller rivals to focus on higher-value transactions, where the economics are more attractive and the path to monetisation is clearer. That would mark a subtle but important shift in the competitive landscape. Instead of competing purely on consumer reach or cashback-led acquisition, smaller apps may need to specialise in merchant categories, premium use cases or regional niches where they can defend margins. In effect, the market could become less about broad-based volume chasing and more about transaction quality, merchant mix and geographic depth.
Competitive Pressure Builds
For India's digital payments sector, the broader implication is that policy is beginning to reward the platforms that can convert scale into durable economics. UPI has been a public digital infrastructure success story, but its commercial model has remained underdeveloped relative to the size of the ecosystem. The introduction of merchant fees above Rs 2,000 does not overturn that model, but it does create a new layer of monetisation that may accelerate consolidation around the strongest brands.
That consolidation risk is especially relevant for smaller competitors, which may struggle to match the distribution, merchant relationships and consumer trust enjoyed by PhonePe and Google Pay. If the largest apps can monetise more effectively while continuing to expand into underpenetrated markets, the gap between leaders and challengers could widen further. For merchants, the change may be manageable at first, but over time it could influence acceptance behaviour, pricing strategies and the mix of payment methods offered at checkout.
The policy also arrives at a moment when India is trying to balance financial inclusion, digital innovation and sustainable business models for its payments infrastructure. The new fee regime suggests a willingness to let the market support the cost of scale, rather than relying indefinitely on zero-fee economics. For the dominant UPI platforms, that is a clear advantage. For the rest of the field, it is a reminder that in India's payments market, size is increasingly becoming a moat.
