India's latest shift in the economics of Unified Payments Interface, or UPI, is likely to strengthen the very platforms that already command the market. According to Bernstein estimates, PhonePe and Google Pay could collectively earn about $900 million a year by March 2028 under the new merchant fee regime, a development that may further entrench their lead in the country's fast-growing digital payments ecosystem.
The policy change introduces a 0.4% fee on merchant transactions above Rs 2,000, altering the long-standing assumption that UPI is a near-zero-cost rail for most users and businesses. While the charge applies only to higher-value merchant payments, the implications are broader. Payment apps with scale, distribution, and merchant relationships are better positioned to absorb the operational complexity and monetise the shift, while smaller competitors may struggle to match the economics.
Fee Regime Rewrites Incentives
The new structure marks a notable evolution in India's payments policy. UPI has been central to the country's digital public infrastructure, enabling instant bank-to-bank transfers at massive scale and helping India become one of the world's most active real-time payments markets. By adding a fee on merchant transactions above a threshold, policymakers are effectively creating a revenue pool that can be captured by the largest platforms with the deepest merchant networks.
For PhonePe and Google Pay, the opportunity is not just in direct fee income. The regime could reinforce their ability to invest in merchant acquisition, incentives, and product development at a time when scale matters more than ever. Bernstein's projection suggests that the fee shift may convert UPI from a largely utility-like service into a more commercially durable business for the dominant players.
The change also reflects a broader policy balancing act. India has long encouraged digital payments adoption through low-cost or subsidised rails, but the government and ecosystem participants are increasingly confronting the question of how to sustain infrastructure, distribution, and innovation without relying indefinitely on public subsidy. The new fee regime appears designed to preserve UPI's reach while allowing some monetisation at the top end of merchant activity.
Dominance Meets Distribution
PhonePe and Google Pay already sit at the centre of India's UPI landscape, and the new fee structure may widen the gap between them and smaller rivals. In payments, network effects are powerful: consumers follow merchant acceptance, merchants follow consumer demand, and both tend to concentrate around the most trusted and widely used apps. A fee regime that rewards transaction value rather than sheer volume may favour platforms with the broadest merchant coverage and the strongest brand recognition.
The policy could also push payment apps to expand more aggressively in rural India, where merchant digitisation remains uneven and transaction sizes are often lower. If larger platforms can build deeper rural penetration, they may secure future high-frequency users before competitors do. At the same time, smaller players may be nudged toward higher-value transactions and niche use cases, rather than competing head-on in the mass market.
That would have implications beyond payments alone. UPI has become embedded in the broader mobility and automotive ecosystem, from fuel purchases to vehicle servicing, toll-linked payments, and EV charging. As digital payment acceptance spreads across transport and mobility touchpoints, the platforms that control the payment layer gain leverage over adjacent commerce categories. For companies in automotive, EVs and mobility, the economics of UPI acceptance can shape customer experience, merchant onboarding, and transaction costs.
Smaller Rivals Face Pressure
The likely outcome is not a sudden collapse of competition, but a gradual tightening of market structure. Smaller payment apps may find it harder to justify broad consumer subsidies if the most lucrative merchant flows continue to consolidate around the largest incumbents. Some may respond by specialising in premium merchants, enterprise payments, or specific verticals where transaction values are higher and customer acquisition is more efficient.
That said, the new regime could still create room for innovation. If the fee framework encourages better monetisation, it may support investment in fraud prevention, merchant analytics, and value-added services. But the immediate strategic effect appears clear: the biggest platforms are likely to get bigger, and the economics of scale in India's digital payments market may become even more pronounced.
For policymakers, the challenge will be to ensure that monetisation does not slow adoption or reduce competition in a system that has become foundational to India's digital economy. For the market, the message is more direct. In UPI, size is increasingly becoming a moat, and the latest fee shift may turn that moat into a wider trench.
